BACKGROUND OF THE INVENTIONModern mobile devices provide many functionalities including telephony (e.g., cellular phone, VOIP), PDA (personal digital assistance) (e.g., contact/address list, games, photos), network connectivity (e.g., Internet web browser, email, short message service (SMS), mapping/location services). Generally, the mobile device user explicitly controls which applications/functionalities to use at a given moment. For example, the user might use SMS services (or texting) at any location where there might be network connectivity. Given that the network connectivity has become more prevalent, the mobile device users tend to use the functionality of mobile devices in more places and situations.
An example of these mobile device functionalities is the text messaging (or texting) which is a communication method between mobile devices over cellular networks wherein short written messages are exchanged between mobile telephone devices, using a communication service standard commonly known as SMS. Given the gateways between the IP networks and telephone networks, one or more SMS users may be on one or both types of networks. This messaging service has been extended to Multimedia Messaging Service (MMS) to include multimedia messages, e.g., containing video, still image, and sound.
This method of communication and its underlying technology has grown to such a great level that it has become one of the most widely used form of mobile communication in the world, wherein almost every mobile phone service provider has made it available to its users as part of its service, covering several billions active users, spanning almost every age group.
The typical mobile device (shown schematically in
Typically, DSP performs under the control of microprocessor/controller (615), and may further be coupled to an application specific integrated circuit (ASIC) block (614), where it can help with the operation of DSP in some application specific functions in the background, as known to those skilled in the art. RF interface block which is coupled to DSP, receives digitally processed base band signal from DSP, and it for example performs quadrature (complex) modulation on the digital base band signal, converts the modulated digital signal to analog form, using digital-to-analog converter, and sends the modulated analog signal to transmitter block (618) for further frequency up conversion to radiofrequency (RF), for wireless transmission through power amplification block (621) and antenna (622).
In the receiving side of mobile telephone system, downlink wireless RF signals are received by the receiver block (619) via the antenna. Receiver block amplifies the received RF signal through an automatic gain control unit, down converts the amplified RF signal to intermediate frequency (IF) by mixing it with a locally generated reference signal (620), and passes the IF signal on to interface block (616) for quadrature (complex) demodulation, with filtering and analog-to-digital conversion as is well-known to those skilled in the art.
Digital signal processor (DSP) block receives the digitized IF signal from the interface block and performs various signal processing techniques such as demodulation, equalization, error detection/correction, and signal detection, and forwards the detected signal (i.e. voice) to audio interface block, to be converted to analog voice, amplitude controlled (i.e. amplified or attenuated) and sent to the speaker block.
As those skilled in the art recognize, most of the above operation is performed under the control of microprocessor/controller block (615). In a typical mobile telephone system, as depicted above, microprocessor/controller block performs such functions as level 2/3 protocol, radio services management, man/machine interface, operating system (OS) software, and short message service (SMS). The operations of both keyboard and display (617) are under the control of the microprocessor/controller. Mobile devices also include local memory/storage (623) used by the processor and/or other components of the system.
As is known to those skilled in the art (and from sources such as printed publications or online technical articles, e.g., WIKIPEDIA® (An Internet community information web site)), during the text messaging, microprocessor/controller receives alphanumeric information from the keyboard, uses SMS services software embedded in its memory, converts the alphanumeric information into short message format, and typically sends the generated message to DSP to be processed and sent over the control channel to a short message service center (SMSC), which provides a store-and-forward mechanism to forward the text messages to the intended recipient.
Although this method of communication service has provided unprecedented level of mobile phone subscriber service, it may be desirable to limit/disable the use of some of mobile device features which could cause distraction to the user when the user is engaged in another activity. For example, statistics indicate that the likelihood of being involved in a traffic accident, while driving and using a handheld device, is four times more than any other situations. One the other hand, it may be desirable to enable other mobile device features based on occurrence of events related to the user or environment. For an example, this invention addresses controlling the mobile device features, such as SMS, while the user is in a vehicle.
SUMMARY OF THE INVENTIONThis invention provides for controlling mobile device functions and features. For example, an embodiment of this invention limits or disables the use of some of mobile device features which could cause distraction to the user when the user is engaged in another activity. An embodiment of this invention enables other mobile device features based on occurrence of events related to the user or environment.
An embodiment of this invention addresses controlling the mobile device features, such as SMS, while the user is in a vehicle.
An embodiment of this invention restricts the ability of the driver of a vehicle to text while the vehicle is in motion, by automatically disabling the texting ability of mobile device within and around perimeter of driver's seat, while the vehicle is in motion.
Other variations, examples, improvements, detection mechanisms, models, techniques, calculations, verification mechanisms, and features are also described in details.
In one embodiment of this invention, as illustrates in
In one embodiment, when localized transmitter/transceiver (e.g., 108) is activated (e.g., by turning on the vehicle (e.g., ignition) and setting the gear outside of Park position), the localized transmitter/transceiver sends a code.
In one embodiment, when the RF signal level received (400) by the mobile device from a localized transmitter/transceiver (e.g., 108) is above a threshold signal level power, the mobile device decodes (or processes as in another embodiment) a code sent by the localized transmitter/transceiver. In one embodiment, the effective range (e.g., 102) of transmitter/transceiver is set so that within the effective range, the received power level by a mobile device (e.g., 126) is above the threshold signal power level, while substantially outside the effective range (e.g., at 120, 122, or 124), the received power level by the mobile device from the localized transmitter/transceiver (108) is lower than the threshold signal level power.
As illustrated by
In one embodiment, the duration of the feature modification is a set (450) to a period of time (e.g., 30 seconds).
In one embodiment, upon occurrence of other events (e.g., an emergency event indicated by a signal/input to the mobile device), the disabled or limited feature of the mobile device is restored. In one embodiment, when user dials an emergency number or the mobile device enters an emergency mode, the disabled or limited feature of the mobile device is restored.
In one embodiment, when the code received from the localized transmitter/transceiver indicates e.g., an enabling event, the mobile device terminates the period of feature modification and restores the corresponding feature/functionality. For example, if the driver sets the vehicle on the Park position, the localized transmitter/transceiver sends an enabling code to the mobile device indicating that the feature (e.g., SMS) can be restored. In an embodiment, where a status of vehicle (such as speed) is used to determine the modification of a feature, when the vehicle comes to full stop, the limited feature becomes enabled again (e.g., after a predefined period of time such as 10 seconds), e.g., by sending an enabling code to the mobile device from a localized transmitter.
In one embodiment, the configurations and rules are dynamically configurable via the user interface on the car computer/control, the mobile device, or a remote server (e.g., a web server). In one embodiment, the operational settings (e.g., how often the code is transmitted by the transceivers (e.g., every 15 seconds)) is also configurable via a control panel (e.g., attached to a localized unit via a car computer panel, or via the mobile device).
In one embodiment, when the mobile device receives a code indicating an event to modify (e.g., limit/disable) a feature (e.g., SMS), and the feature is already modified (440) (e.g., SMS is already disabled/limited, e.g., due to prior code transmission), the remaining time period for maintaining the feature modification is extended to a predefined time period (e.g., 460). In one embodiment, the extending time period is the same as the original time period for feature modification. In another embodiment, the extending time period is shorter or longer than the original time period for feature modification. For example, in one embodiment, upon receiving the code from the localized transmitter/transceiver, the SMS feature of the mobile device is disabled/limited for 30 seconds. If after 25 seconds, similar code is again received by the mobile device, the remaining 5 second turns to 30 seconds, in an embodiment for which the original time period is the same as the extending time period for the feature modification. However, in one embodiment, when the extending time period (e.g., 4 seconds) is shorter than the original (e.g., 30 seconds), the remaining time is extended if the remaining time is less than the extending time period. In this example, the remaining time period remains as 5 seconds because it is more than 4-second extending time period. In one embodiment, the remaining time is tracked in a variable (memory location). In one embodiment, the expiration time is stored in a variable (memory location). In one embodiment, the remaining time is updated periodically or the expiration time is checked against the current time (e.g., from local system or synchronized from network via NTP) periodically to determine when expiration is reached.
In one embodiment, one or both of the original time period and the extending time period for the feature modification are configurable on the mobile device. In one embodiment, one or both of these time periods are transmitted to the mobile device via the localized transmitter/transceiver. In one embodiment, the mobile device receives one or both of these time period values from a push (or pull) service from the corresponding telephone carrier or from a server in network or Internet.
In one embodiment, the mobile device is equipped with GPS (Global Positioning System) service or receives its (or vehicle's) position from another GPS system (e.g., from a GPS service on the vehicle or an emergency service provider on the vehicle). In one embodiment, the mobile device or the computer/GPS on the vehicle (periodically or on-demand) determine the locality/jurisdiction/state/country by using mapping/address/location services (e.g., via Internet or a local database). In one embodiment, a change in locality/jurisdiction/state/country is identified by comparing subsequent GPS readings. In one embodiment, upon a change in locality/jurisdiction/state/country, the original time period and the extending time period for the feature modification corresponding to current locality/jurisdiction/state/country is determined, e.g., by querying a local database or downloading data from a service from Internet, and these time values (or other parameters provided by the service, e.g., speed limits) are used subsequently to modify the mobile device feature.
In one embodiment, when and how long to maintain the feature modification is determined by a set of rules and configuration values, which are executed in a rule-based engine (e.g., in a mobile device, vehicle computer, or a server on a network). In one embodiment, the rules are downloaded upon querying by the mobile device or the vehicle's computer based on the geography (e.g., location of the vehicle or mobile device), type of the vehicle, and/or one or more attributes of the driver or passenger(s) (e.g., age, occupation, or exemptions).
In one embodiment, when the mobile device (e.g., 126) whose one of its features is already modified, leaves the effective range of a localized transmitter/transceiver (e.g., 108) or does not receive a further code indicating extension of the feature modification period, the modified feature is restored to previous state when the remaining modification period is over.
In one embodiment, the mobile device keeps monitoring (e.g., 430) for an RF signal from a localized transmitter/transceiver. For example, in one embodiment, a program/task running on the mobile device periodically checks for such signal or is notified by an underlying hardware/firmware/operating system/RF modules that a signal has been received. In one embodiment, the communication between the local transceiver and the mobile device is performed through BLUETOOTH® (A wireless technology protocol) (or related) technology.
In one embodiment, when the signal monitoring application receives a code from a localized transmitter/transceiver, it modifies or triggers modification of a mobile device feature/function (e.g., SMS). In one embodiment, the signal monitoring application is integrated part of function/feature to be modified (e.g., integrated or a module of SMS application). In such an embodiment, a tight integration between the signal monitoring module and core functionality control enables one to modify the functionality directly, e.g., via non-public API (Application Programming Interface) or direct calls. In one embodiment, the signal monitoring application and the feature/function to be modified are not as tightly integrated. In such an embodiment, there are various methods that the feature modification may be achieved. For example, the triggering application (i.e., the signal monitoring application) calls one or more APIs of the triggered application (i.e., SMS application), to modify the feature. In such an embodiment, the triggered application supports modification of the feature via those APIs. In one embodiment, the triggering application modifies configuration data (1360) used by the triggered application and/or other underlying software/firmware/hardware. For example,
In one embodiment, the triggering application identifies (e.g., by querying the OS) the applications/processes that provide the feature to be modified, for example, by using the signatures of those triggered applications. In one embodiment, the triggering application terminates the identified triggered applications (if they are running), e.g., by sending a command to the OS or using an inter-process messaging. In one embodiment, the triggering application prevents launching of the triggered applications via the mobile device user interface, e.g., by temporary disabling access to the triggered application. In one embodiment, the triggering application sends messages via an inter-process messaging to affect the behavior of the triggered application and modify a feature supported by the triggered application.
As illustrated in
In one embodiment, the multiple transmitters/transceivers are positioned so that their effective ranges map the interior of the vehicle where the driver and passengers might be located (and hence, the potential location of the mobile device(s)). In one embodiment, the power level settings of the multiple transmitter/transceivers are adjusted so that their effective ranges better map the interior of the vehicle, in order to make a more accurate determination of the mobile device location especially close to the driver seat (212). For example, in one embodiment, the front transmitters/transceivers (204, 230) are placed close to mirrors (210 and 218) to reduce overlap between their corresponding effective ranges. In one embodiment, the back transmitter/transceivers (232, 234) are placed behind or above the back seat at the left and right sides of the vehicle.
In one embodiment, one or more transmitters/transceivers (e.g., 236) is placed, e.g., about the center of the vehicle. In one embodiment, such a transmitter is used to calibrate the power level of the other transmitters/transceivers (e.g., 204, 230, 232, and 234). In an embodiment, the power level output of the localized transmitters/transceivers are adjusted based on an RF calibration. This, for example, helps keeping the effective ranges stable by keeping the power levels stable, when the output power levels of these transmitters/transceivers tend to drift over time. In one embodiment, additional transmitters/transceivers (e.g., 236) help better position the mobile device.
In one embodiment, a transceiver 236 has a higher effective range than the other local transmitters (e.g., 204, 230, 232, and 234). In an embodiment, the mobile device makes the data communication with transceiver 236, while it determines the received power level signals from transmitters 204, 230, 232, and 234, as well as their unique identifiers. Based on these received power levels, the mobile device determines within which effective range(s) it is located, and the mobile device communicates the corresponding identifier(s) to transceiver 236. In one embodiment, transceiver 236 provides the data to a localized unit, and the localized unit provides a code to be sent to the mobile device via transceiver 236. A localized unit is installed on the vehicle, e.g., behind control panel, dashboard, trunk, floor, etc. In one embodiment, transceiver 236 is wired to the localized unit for signaling and power. In one embodiment, transceiver 236 is integrated with the localized unit. In one embodiment, a localized unit uses a processor/controller to perform logical and other calculations, control the transmitters/transceivers, communicate with the mobile device via transceiver(s), and receive data/status from vehicle's computer/control or sensors.
In one embodiment, as depicted in
In one embodiment, e.g., as illustrated in
In one embodiment, the mobile device location is determined by using the localized transmitters/transceivers. In one embodiment, the location of the mobile device is determined based on the relative timing of signal from the mobile device to the transceivers. In such an embodiment, using the radio wave as media, the time resolution is in order of 1 nsec or less, and the transceiver(s) have stable clocks/reference signal generator (e.g., with low phase noise). For example, one transceiver (e.g., 336) provides a reference RF signal for the other transceivers (304, 330, 332, 334, and 336) to obtain and compare with signals from the mobile device (326).
In an embodiment, the location of the mobile device is determined based on the relative signal power levels from the local transmitters/transceivers, measured at the mobile device. In one embodiment, the power levels are measured at the local transceivers for the signals from other transceivers and the mobile device. Based on the antenna configurations of the transceivers (and other obstacles), a transmitter's signal power level attenuation is dependent on the distance to the transmitter. For example, with the geometric expansion of the radiated wave front, the free space attenuation is given by r2·(4π)2/λ2, where r is the distance to the transmitter and λ is the wavelength of the radiation.
In one embodiment, the relative power levels measured at the mobile device or the local transceivers are used to estimate the relative distances of the mobile device to the local transmitters/transceivers. For example, assuming the attenuation is inversely proportional to r2, in one embodiment, the ratio of distances of the mobile device to two transmitters is proportional to the inverse square root of the ratio of their corresponding signal power level measurements at the mobile device. In one embodiment, once the ratio of distances of the transmitters from the mobile device is determined (for example, by a program on the mobile device or the localized unit), the position of the mobile device is determined with respect to the transmitters.
Given that the attenuation has strong dependence on the distance from the transmitter, in one embodiment, the distance of the mobile device to each transmitter is estimated based on the signal power level received from the transmitters to the mobile device. To help the accuracy of the estimation, in one embodiment, the power level measurement by the mobile device is calibrated by placing the mobile device at one or more predetermined locations with respect to the transmitters during a calibration procedure. For example, in one embodiment, the calibration is performed by placing the mobile device close to the steering wheel, close to dashboard at the front passenger area, on back seats, or in the area between the front and back seats. The calibration is stored (e.g., in the mobile device and associated with the vehicle (300) identification), and it is used to determine the location of the mobile device at a later time. In one embodiment, the calibration program may be run, e.g., in factory, during installation by using a typical or the same mobile device, by authorized personnel, the user, or service repair staff, and the calibration data may be on the mobile device, electronically sent to the user for installation of the mobile device, placed on a server accessible via Internet, for later retrieval, stored on a non-volatile memory/storage of localized unit or accessible to localized unit (such as vehicle's computer/control system).
In one embodiment, the output signal power level of each transmitter/transceiver is measured by other transceiver(s) in order to baseline the relative power output from each transmitter/transceiver, given that the locations of the local transmitter(s)/transceiver(s) remain fixed with respect to each other. For example, the signal output power of transmitter/transceiver 304 is measured by one or more of transceivers 330, 332, 334, or 336. Comparing these power measurements with a set of previously calibrated power measurements provides the amount of deviation in transmitted output power from transmitter/transceiver 304, since the prior calibration. For example, if signal power from transmitter/transceiver 304 (as measured by other local transceivers) has dropped 2 dB (compared to the that during calibration), while the output signal power level out of transceiver 330 (as measured by other transceivers) has increased 1 db since calibration, then in one embodiment, the relative output signal power measurements of the transceivers 304 and 330 (at the mobile device) is adjusted 3 dB compared to that during the calibration. Then, in one embodiment, the adjusted measured transmitted output signals (i.e., adjusted by 2 dB and 1 dB, respectively) and/or the adjusted ratio of the transmitted output power signals (i.e., adjusted by 3 dB) are used as correction factors in estimating the distance of the mobile device to the transmitters.
In one embodiment, the baseline power output measurement(s) of each local transmitter/transceiver (as measured by other local transceivers) is communicated to the mobile device via a transmitter/transceiver (e.g., 336) (or used by localized unit), and the deviations of these baseline power levels from those of the calibration are used as correction factors when determining the distances (or relative distances) of the mobile device to the local transmitters/transceivers. In one embodiment, during calibration of the transmitters/transceivers, the output signal power levels of local transmitters/transceivers are measured at some predefined distance(s) to the transmitters (e.g., 2 feet and 4 feet), in addition to the measurements at the output signal power levels by the other local transmitters/transceivers. This measurement aids in determining more accurate measurement of the distance to each transmitter by providing direct sample point(s) linking the transmitter output power to the distance.
For a (hypothetical) example in an embodiment, as illustrated in
In an embodiment, the analysis considers/assumes n number of transceivers (e.g., n=5, in
In one embodiment, the analysis assumes a blockage between the individual transmitters and receivers (i.e., not specific to individual receivers or transmitters). In an embodiment, the blockage matrix Bij (1≦i, j≦n, e.g., expressed in dB) would represent the blockage between the ith transmitter/transceiver and the jth receiver/transceiver. In one embodiment, diagonal terms are set to zero (i.e., Bii=0). In such embodiment, there are n. (n−1) variables in the blockage matrix. In one embodiment, the off-diagonal terms are symmetric, i.e., Bij=Bij, reflecting an assumption that the signal attenuation is symmetric with respect to the direction of signal propagation between transceivers. In such an embodiment, there are n. (n−1)/2 blockage variables. In one embodiment, there are n number of transmission power drift variables, with Di representing the power drift for the ith transmitter (e.g., in dB) since its calibration. In one embodiment, there are n. (n−1)/2 blockage variables Bij and n number of transmission power drift variables Di. Therefore, in such an embodiment, there are n. (n+1)/2 number of variables. In one embodiment, there are n. (n−1) power deviation data points (as explained above). Therefore, for n≧3, there will be the same or more number of data points than variables, providing a redundancy for cross checking or averaging the results. (For example, for n=5, there are 15 variables and 20 power deviation data points.) For n<3, in one embodiment, other estimations, assumptions, diagnostic information (e.g., the input/settings/readings) from transceivers are used to estimate the variables. In one embodiment, given that all the values of power drift and blockages can be increased by same factor without affecting the perceived power measurement, there is an additional normalizing equation (constraint) that would supplement the number of power deviation data points. In another words, the values of the blockage variables and power drifts may be normalized, e.g., based on the smallest blockage value. In such an embodiment, for n<3 (e.g., n=2), instead of just assuming two power drift variables (D1 and D2) and one common blockage variable (B12), the additional normalization constraint provides that B12 be zero if both D1 and D2 have the different signs (in dB), or one of D1 or D2 be zero if they have the same sign in dB. In one embodiment, the values or allowed/estimated ranges for Dis are determined based on preconfigured values/limits, and/or readings/settings/input to the transceivers. These would provide additional constraint to reflect more accurately the determination of the power drift and/or the blockage in the system.
In one embodiment, if the power output of the local transmitters/transceivers, their receiving antennas and power measurements, and their propagation obstacles are similar, the ratio of measured signal power level (by the other local transceivers) should track as expected with the distance to each transmitter. In one embodiment, a consistent large deviation (e.g., drop) in the power measurement by other transceivers indicate that the transmitter is not working properly or it is blocked by an unusual obstacle. Therefore, in one embodiment, the user is notified via communications from the localized unit to the mobile device (or the vehicle's computer system) in order to notify the user through a user interface (e.g., audio and/or visual) about the issue. In one embodiment, the blocked transmitter is identified to the user by its location on the vehicle, e.g., by matching its identifier with its location using a query on a preconfigured table(s) having the transmitters/transceivers IDs and their installed locations and/or description. Such table(s) is stored/maintained on localized unit, the mobile device, and/or a remote server accessible via the mobile device and/or the localized unit (for example through its own communication device, the vehicle's computer/communication system or the mobile device).
In one embodiment, the blockage variables and/or power drift variables are calculated based on the calibration and baseline data measurements. In one embodiment, the user is notified about abnormal blockage or power drift via a user interface (e.g., on the mobile device or car computer/control system) or by email, SMS, or other communication means/mediums. In one embodiment, identifying data and information are sent from the localized unit to the vehicle computer/control or the mobile device. In one embodiment, if the blockage amount is more than a preconfigured threshold, the user is warned about the blockage and/or its location based on the identity of the transmitter(s)/transceiver(s). For example, the user may be warned that there is an object blocking the transceiver on the right side of the back seat (e.g., 332 in Blocks 382 and 386). Or the user may be warned that there is a blockage, between front passenger and left back seat transceivers (i.e., 330, and 332). This could occur when for example a large metallic object is placed on the front passenger side seat. In one embodiment, if the calculated power drift and/or the amount of blockage are more than their respective thresholds, those measurements affected by the power drift and/or blockage are disregarded when estimating the distance of the mobile device to the transmitters/transceivers. In one embodiment, if the amount of power drift is less than a threshold, the localized unit adjusts (e.g., increases or lowers) the power output setting on the particular transmitter (e.g., in multiple steps with baseline re-measurements). In one embodiment, the statistics of the adjustment and/or power measurements are kept in memory/storage or sent to a server or the mobile device, for further analysis such as identification of degradation in the system.
In one embodiment, the vehicle sensors, such as weight monitoring on seats (e.g., as used to detect a seated passenger), are used to estimate the approximate blockage expected from the passenger(s), or used to check/validate the blockage variables obtained, e.g., from baseline measurements. In such an embodiment, the sensor data may be used directly or via the vehicle's computer system. In one embodiment, the vehicle/sensor status and data is sent to the localized unit or to the mobile device (e.g., after determining that the mobile device corresponds to the vehicle, via e.g., owner, or a family plan).
In one embodiment, the power drift and blockage factors are used to adjust the measured transmitted signal power of the localized transmitters/transceivers at the mobile device. The output power transmitted by the local transmitters/transceivers may be different even during their calibration; therefore, the output signal power of the local transmitters/transceivers (during calibration) measured at some predefined distance(s) to the transmitters (e.g., 2 feet and 4 feet) are used to better estimate the mobile device distance (or relative distances) to the transmitters. For example, in one embodiment, assume that it is estimated that the output power of transmitters 304 and 330 have drifted by −2 dB and +1 dB, respectively (e.g.,
In one embodiment, as illustrated in
In one embodiment, once the distances of the mobile device are approximated with respect to the local transmitter/transceivers, a triangulation technique is used to map the location of the mobile device compared to features of the vehicle, based on the locations of the transmitters/transceivers with respect to the vehicle (e.g., see
In an embodiment, the accuracy of locating the mobile device is enhanced by using the same mobile device or similar tool to measure the transmitted output power of the local transmitters/transceivers at certain distance(s) from the transmitters, during the calibration. This is because, in the embodiment, the measured power levels by the mobile device (e.g., at or about the same time as the baseline measurements) is compared with the calibrated values to attribute the deviation to the spatial dependence of the wave form attenuation. If the device(s) used during the calibration phase is different from the mobile device in measuring the transmitted signal power of the transceivers (e.g., due to the antenna size, other calibrations, or internal power gain/amplification), the difference in the power readings between two devices (i.e., calibrating device and the mobile device) can cause an offset in the perceived distance from the transmitter. For example, if the power readings differ by 3 dB (i.e., about twice as much), the offset in the distance estimation would be about 41% (=10(3 dB/20 dB)). Due to the logarithmic dependencies, small deviations in power readings do not significantly impact the distance estimation. For coarse measurements and location of the mobile device within or about a vehicle, in an embodiment, the tolerances can also be applied when defining the triggering regions (e.g., 390), for example, by expanding/inflating its boundaries.
In one embodiment, the power measurements of the transceivers output signal by the mobile device and the calibrating tool(s) are converted to power density measurement, based on the rating and specifications of the measuring tools and device. By normalizing the power values to power densities, in one embodiment, the peculiarities of the measuring devices are effectively masked from the analysis. For example, instead of measure the output power as dBm, in one embodiment, the measured value is converted to, for example, dBm/cm2 to reflect the power density. In an embodiment, the measured power densities are similarly adjusted for power drift and blockage estimations. In one embodiment, the transceivers' measurements of other transmitters/transceivers transmitted output signal power during calibration or baseline measurements are also similarity done based on power density.
In one embodiment, the output power transmitted by a local transmitter is estimated by utilizing the circuitry and meters on the transmitter itself. A prior calibration and rating can also be used to estimate the transmitter output power based on the settings and/or input to the transmitter. In such an embodiment, the measurement of the transmitter's output at predefined distance(s) from the transmitter (during calibration) may become optional or require less number of measurements, as an alternative way to measure and monitor the transmitter's output power is provided by the transmitter itself. In an embodiment, the output power levels (and/or the settings and input parameters) of the transmitters/transceivers are stored during the calibration phase. In one embodiment, the transmitted signal output power of a transmitted is converted to a power density value at a given distance (e.g., 2 feet) from the transmitter based on the type of the transmitter and/or known or estimated theoretical/empirical power density vs. distance relationships.
In one embodiment, the mobile device distances to the local transmitters are estimated based on the power ratios received from multiple local transmitters. In one embodiment, as illustrated in
In one embodiment, the location of the mobile device is determined by using the calculated ratio of the distances of the mobile device to the transmitters/transceivers. For example, as illustrate in
Note that since here k<1, then γ>1 and a<lc and 0<lc−R<a.
In special case where the distant ratio is 1, both lc and R tend to infinity, as γ tends to infinity and k tends to 1. In this case, the locus of points having same distance to the fixed points simple becomes the perpendicular bisector of segment joining the fixed points.
Similarly, the ratio of distance of the mobile device (326) to another pair of transceivers (e.g., 332 and 334 pair) is used to determine the corresponding locus of points having the same distant ratio to the fixed points (332 and 334). The locus of these points, as depicted in
In one embodiment, intercepting a circle (e.g., 368) associated with a pair of transceivers (e.g., 304 and 330 pair) with another circle (e.g., 374) associated with another pair (e.g., 334 and 332 pair) narrows and limits the possible locations (e.g., 326 and 320) of the mobile devices with respect to the transceivers, as the intercept points of the circles. For example, considering 4 transceivers (
In one embodiment, a hybrid approach is taken to determine the location of the mobile device. For example, two (or three) circles associated with two (or there) transceiver pair are intercepted to determine a narrowed potential locations for the mobile device. Then, a transceiver (e.g., 336) is used to determine the distance to the mobile device using a power level approach. This way, for example, one embodiment discriminates between the potential locations of the mobile device (e.g., 326 and 320) by comparing the estimated (based on power level) distance from the mobile device to the transceiver (336) to the distances (350 and 353) from the transceiver (326) to the potential locations (326 and 320, respectively) of the mobile device.
In one embodiment, the power levels (or density) transmitted by the local transceivers are mapped for each transceiver on and/or around vehicle, e.g., by using actual measurements during calibration, empirical results, simulation, and/or estimations, with/without passengers or with different arrangements of passenger seating. Based on this power level mapping, a set of contour maps are generated to reflect a loci of points having the same ratio of the power (or density) between the two transceivers (pair) for a set of ratios (e.g., expressed in dB). Then, in an embodiment, the contours are used to map, e.g., by interpolation or extrapolation between contour lines, to determine a contour representing the determined distance ratio corresponding to the transceiver pair. Then, in one embodiment, such interpolated/extrapolated contour lines from multiple transceiver pairs are superimposed to determine their intercept points as potential location of the mobile device. In previous examples, the contour lines were represented by intercepting circles. In one embodiment, the location of the mobile device is estimated as an average location of a cluster of intercept points that are closely located with each other. In one embodiment, if the contours (or circles) do not actually intercept, a stand-in pair of intercept points which define the shortest segment connecting the contours (or circles) are used instead.
Similarly, in one embodiment, the signal power levels are measured and calibrated under various occupancy of the vehicle and this data is used later to determine the location of the mobile device by looking up the determined power levels/ratios in the gathered data and performing interpolation/extrapolation on the gathered data points.
In one embodiment, for example using BLUETOOTH® (A wireless technology protocol) or similar technology, for establishing the transceiver rangers (e.g., 102) or used to locate the mobile device within a vehicle (e.g.,
Generally, when a transceiver attempts to participate in a power-controlled link with another transmitter, it needs to measure its receiver signal strength and determine if the other transmitter should modify its output power level. This is achieved for example via Receiver Signal Strength Indicator (RSSI). The instructions for modifying the transmission power are provided by the LMP (
In one embodiment, directional transceivers/transmitters are used to tailor the ranges (e.g., 102) and coverage. Due to its angular dependence of their signal power, the distance of the mobile device to the transmitter may not be accurately estimated in all directions only based on the measured power level measured at the mobile device. In one embodiment, the transmitted power is lowered to limit the size of range. In one embodiment, overlapping (directional) ranges are established (e.g., in a checkerboard pattern) by multiple transceivers, so that by identifying which transceivers cover the mobile device, it is effectively determined in which overlapped portion of the corresponding ranges, the mobile device is potentially located.
In one embodiment, as illustrated in
As shown in
In an embodiment, other or additional vehicle status (e.g. speed), road status (e.g., rainy), passenger status, and/or information (e.g., from vehicle's sensors such as outside lighting) are used to send an appropriate code to the mobile device. In an embodiment, where only one code is sent to the mobile device (e.g., indicating modification of a feature), logically or physically, the selection step (e.g., via MUX (804)) may be implemented differently or eliminated.
Similarly, as shown in
In one embodiment, the mobile device sends a message to a remote server/service when modifying a feature. For example, in one embodiment, when disabling SMS feature on the mobile device, the mobile device sends a message to SMSC to store (i.e., to hold) the incoming messages, until the hold is removed, e.g., by sending another message to SMSC to forward the messages to the mobile device.
In one embodiment, the communication can go between 1058 and 1074 (or between 1074 and 1052), instead of (or in combination with) communication between 1054 and 1074.
In one embodiment, a first mobile device (e.g., 202) functionality is limited/disabled/modified due to its entrance in effective range of transceiver 204 (close to the driver's side). As the result a message is sent to, for example, a remote server/service/SMSC to flag the first mobile device as modified featured. In addition, the vehicle/transceiver ID associated with the first mobile device is also sent and stored at the remote service (e.g., in a database), as described earlier. As shown in
Similarly, in one embodiment, the status of each mobile device (e.g., 226 and 222) are determined, and the function or message tasks are forwarded to 222, by the central server. Mobile device 226 is deactivated, partially or fully, e.g. at least for the functions that were forwarded to mobile device 222. The identification steps are done at steps 500 and 530, and the decision steps are done at steps 510 and 540, with decisions to keep monitoring at steps 520 and 550, and final step of forwarding the tasks at step 560.
In an embodiment, where one mobile device is shared between the driver and one or more passengers, (e.g., a mobile telephone belongs to the driver originally), and it is within the feature deactivation/disabling range of the driver seat, as determined by any of the methods mentioned in this disclosure, such as using items 204 and 230 for transmitter/transceiver (as an example), or ranges 202 and 231, for the driver and passenger, and a mobile device, e.g., item 226 in
In one embodiment, when the phone moves back, from range 231 to range 202 (e.g., handed from a passenger on seat 214 to the driver on seat 212), then a message is sent to the center, a server, or SMSC, to update that the mobile device (e.g., a cellular phone) is now within a feature deactivation/disabling range, and thus, the system does not let the driver use e.g., the texting functionality from then until the situation changes again, in the future.

Note that the teaching in this disclosure also applies to any wavelength, RF, infrared, X-ray, microwave, radio waves, laser, other parts of electromagnetic spectrum, visible, or invisible parts, plus sonar, radar, Doppler effect, sound waves, shock waves, or ultrasound waves. In one embodiment, an array of antennas is located on the top of the roof of the car, or inside the door of the car. The teaching in this disclosure also applies to the reflection, transmission, refraction, or emission, by/from/deflected by/through antennas, objects, human, users, drivers, passengers, telephones, tags, smart cards, IDs, RFID, or mobile devices, either active or passive (no battery or power, for example), and detected or received by some other dishes, antennas, detectors, sensors, CCDs, sensitive films, sensitive transistors or diodes, recording media, storage media, counter, accumulator, lenses, or semiconductor layers, to find/determine the location of users, telephones, and other objects, in the car or at other places.
In one embodiment, the sensor/transceiver or multiple sensors/transceivers are placed in a vehicle (moving object, or any object, in general). In one embodiment, the RFID (active or passive) technology is used, and RFID transceiver(s) are placed at the steering wheel, dashboard of the car, roof, door(s), mirror (center one, or on the side of the car), sun-visors, or other locations in the car. In one embodiment, the one or more sensors or detectors are placed near the driver or closer to the driver of the car. In one embodiment, a range threshold (e.g.,
In one embodiment, an array of antennas is used, to make the signal directional. In one embodiment, the transceivers are placed at the ceiling of the vehicle or close to the floor (e.g., under the seats).
In one embodiment, the driver is excluded, but others on the car are not excluded, to perform a task (or have an option or functionality on the mobile device) or send/receive some signal or information. In one embodiment, some locations in the car are designated as hotspots, to be excluded, or to be included, to perform a task or receive some signal or information. In one embodiment, some locations in the car are designated as hotspots, in combination with a context (for example, the type of message, the sender, the identity of the receiver, the time of the message, the length of the message, or the content of the message, such as Private Message, Emergency Message, Financial Message, or “For The Person Named Joe Smith Message”), to be excluded (e.g. cannot do it), or to be included (e.g. can do it, or vice versa), to perform a task (or receive some service) or receive some signal or information.
Note that “can-do-it” situation can be generalized to all these situations. The user (limiting in terms of time or number of functions and tasks):
-
- can do it,
- or partially do it,
- or with limited option do it,
- or sometimes can do it,
- or conditionally can do it,
- or can do it as a group,
related to a task, sending or obtaining an information or warning message, or disabling or enabling some functions, options, displays, turning on devices or circuits, or menu.
In one embodiment, a context alone (or in combination with the other parameters) is the deciding factor for the determination, to be excluded, or to be included, to perform a task or receive some signal or information. In one embodiment, the identity (e.g. by name, subject to verification, by biometrics, PKI/private/public key, symmetric encryption, smart card, PIN/code, personal ID/password, or their combinations), or the position of the person (e.g. parent (of the driver or user), mother, father, guardian, owner of the business/car, boss, family member, an adult, police, authority figure, owner of the car, power-of-attorney, proxy, or court-appointed person), is the determining factor (alone, or in combination), to be excluded, or to be included, to perform a task or receive some signal or information.
In one embodiment, the biometrics includes the conventional identification methods, such as face recognition, knuckle recognition, eye recognition, iris recognition, finger-print, finger recognition, signature, voice recognition, handwriting recognition, or pattern recognition, for identification or verification of the presence of the user/driver/passengers in the car, located at various point(s) in the car, for various seats/user(s), with one or more sensors or cameras in the car, and a central processing unit, in the same car, or in a remote location.
In one embodiment, for train, metro, or any public transportation means, the operator's usage can be blocked, and at the same time, a message/warning will be sent to the main station about the attempt or the actual usage of the operator, with proper recordation in a central server, with a time-stamp and number of occurrences. It can cause the emergency brake, disabling the control from operator side, or transferring the control to the headquarters.
In one embodiment, the message or warning can go to the same user, and/or his/her parents, his/her boss, third party (e.g. police), or anybody designated by the user or others. It can be in the form of each or combination of the following: text, telephone call, ring, audio, multimedia, movies, video, siren, vibration, light, flashing light, smell (e.g. releasing/spraying a sharp smell, from a chemical reservoir, container, or box, to warn or shake the user), voice message (standard or customized warnings, by user's voice or others'), predetermined message, customized message, real-time message, automatically conference call initiation, giving options on the user's telephone or computer/computing device, giving options on another person's telephone or computer/computing device, and/or specific music, song, sound, or note, for a specific situation, customized or assigned to, by the user or a third party, to remind the person or user about the specific situation. For example, a specific sound or music may/can/will remind or signal the boss (e.g. owner of the shipping company) that the user/driver/operator number 5 (e.g. among/out of his 25 drivers) has activated the warning or message.
In one embodiment, the following one or more conditions (or their inverse or negative logic counterparts) must be met, to activate the warning or message, to cause an action or task, or to start, enable, stop, or disable a function or task (e.g. stop getting and/or sending text messages and/or voice messages, or both, except, e.g., for to/from emergency numbers (911) or parents' number(s), or alternatively, with no exception, as another embodiment), for user or a third party, determined in real-time or pre-determined before, by user, system, government, laws, rules, or third party:
-
- ignition is on,
- the key is in ignition slot,
- the car is in the Parking mode,
- the car is in the Drive or Reverse mode, but otherwise stopped by applying brakes,
- the car is moving,
- the car is slowing down (or deceleration),
- the car is speeding up (or acceleration),
- the hand-brake is applied,
- the car is stopped, but the engine is running at idle,
- the tires or wheels are sliding or rotating,
- the speedometer shows a non-zero value,
- the engine speed (RPM, round per minute) shows a non-zero value, and/or
- the car is in the Drive or Reverse mode, and also moving.
The conditions above can be AND-ed, OR-ed, NOR-ed, XOR-ed, or logically combined in other forms, to set more or fewer constraints or conditions on the user or driver, in terms of functions available to the user, regarding his mobile device, PDA, laptop, computer, GPS system, multimedia display, DVD player, CD or CD-ROM player, radio, cell or mobile phone, pager, walkie-talkie, computing device, communication device, or any other device or appliance available as mobile or in the car (or even limiting the functions of the car, such as limiting the gears on the gearbox or stick shift, stopping or slowing the engine, stopping the gas supply, turning off the radio, or similar functions in the car). One can customize the conditions above, for example, one can set the following, as the condition (rule-based condition can be downloaded automatically or pushed from a server maintained, e.g., by a government entity/agency):
IF
-
- (The speed of the car is more than 3 miles per hour, AND (the handbrake is not applied, OR the car engine is running, OR the car is not in the “Parking” mode, OR the car key is in the ignition OR activated remotely (for keyless ignition systems)))
THEN
-
- (Disable the texting function in the phone,
- AND send a message to the central location, informing the parents,
- AND turn off/disable the radio, DVD player, and TV in the car,
- AND turn on the headlights on the car, automatically.)
Thus, any kind of condition and restriction/consequences can be applied in the logic of the operation, as long as there is a sensor or device to detect that condition, and there is a switch or controller to disable/enable/control/adjust the outcome, equipment, or parameters. One CPU, server, or central computer in the car (or remotely) can control and adjust all parameters and equipment, sending multiple signals and warnings to different locations for various tasks and acknowledgements (as an example).
In one embodiment, the choices or options are all disabled, partially disabled, all enabled, partially enabled (e.g. disabling text, but still enabling voice functions, or hands-free options), or time-delayed (for example, after the car and/or engine stops (either or both, for different embodiments), enabling the text functionality, delivering the message, or turning on the telephone).
In one embodiment, the BLUETOOTH® (A wireless technology protocol), using a universal code, can be used for transmission and communication between the devices and the telephone. The application can run in the cell or mobile phone, or alternatively, in a central place or server, as a remote location, for example. In one embodiment, the application can run in the background, and checking periodically for the status, to activate or deactivate some function(s)/option(s) or do some task(s). In one embodiment, the telephone is a “smart” device, i.e. all or most of the decisions and processing units are in the handset, itself. In one embodiment, the telephone is a “dumb” device, i.e. all or most of the decisions and processing units are in the central location, e.g. on a server, or at the headquarters, e.g. in a remote place, such as at the telephone company. In one embodiment, the software or updates are pushed from carriers, telephone, car, rental, or service companies (or local/state/federal governments), to individual devices or telephones. In one embodiment, the user downloads the codes or execution software, using hash function or encryption, for security, from a web site or a central place/server.
In one embodiment, the command or the signal from the processing unit forces the engine or car to stop, or put on the brakes for the car, slowly or immediately, or prevent/restrict texting or telephone functions, partially or fully (e.g. turn off the texting unit, or the phone altogether, on the first try, or on the second/third try, by the user, for example, or restricting more on the subsequent tries, for the functionality of the phone or texting, as another example, which requires a counter to count the number of attempts).
In one embodiment, the system is in an enclosure which is tamper-proof. The state or the federal government can check the functionality of the system, on a yearly mandatory basis, so that nobody can open the enclosure or change any settings or parameters within that.
The ID/verification for a person and phone can be obtained from the phone, in one embodiment. In one embodiment, the ID of a person can come from a separate tag, driver's license, key chain, magnetic strip, RFID (passive or active), or smart card (or similar or conventional method/source), while, as a separate (different) source, the telephone ID comes from the telephone (or yet another/third source).
In one embodiment, if the unit is functioning or malfunctioning, the indicator on the car shows to the user, using lights or LEDs, or sound/voice. The police can monitor the status of the unit, or if it functioning properly (e.g. if it was tampered with), using the sensors or signals monitoring the doors, seals, or caps, on the box or enclosure, to find such a status, whenever the car goes for yearly inspection or stopped for any traffic violation, in the close proximity with the police detector or police car. This can be done using, for example, a complete circuit going through the door of the disclosure. So, whenever somebody opens the disclosure, the circuit becomes open, and that can trigger a magnet/wire coil (that feeds from the same circuit) to stop working, causing a metal rod or bar to move a certain direction or drop, by gravity, after the magnet ceases its support or pull on the metal bar or rod, and also, causing some other circuit sending a signal, indicating such tampering and action, to a detector or a central location, such as police. Similar types of tamper-proofing and/or detection have been done by others, and we incorporate any conventional tamper-proofing art here.
In one embodiment, the authorities or authorized personnel can check whether the transceivers are turned on by measuring residual signal power levels around and in proximity to the vehicle.
In one embodiment, tamper proofing is applied to the software modules running on the mobile device and/or localized unit. The tamper checking is performed, for example, when connecting to the service provider/carrier, by downloading a tamper checking software/code/script from the carrier to the mobile device. In one embodiment, the tamper checking software when running on the mobile device checks the feature limiting features of the mobile device (e.g., the triggering program) by use of methods such as determining hash representation of the code and comparing with that from the remote server.
In one embodiment, for the parents, the restriction can be higher than those imposed by the states or federal government, for the children under 18, or above age 18, to drive the car, based on the age and experience, as set by parents. This can also depend on the range of driving, distance from the house (e.g., determined by using GPS), mileage per day (e.g., by using a counter), time of day (more restriction at night), maximum speed, and maximum weight for the cargo for the car. For example, the younger the driver, the more restrictions on the driver, and the less functionality of the telephone, in addition, to limiting the speed of the car, or at least, warning the kid or parents about the high speed (or recording those events with timestamp for future inspection by parents, for exceeding age-related speed limitations or local speed limits).
The cars nowadays have a sensor, based on the weight or pressure, or temperature, which can detect the presence of a person on a seat. In one embodiment, this can be used for detection of the passengers, i.e. the number and positions. For example, if a kid (the driver of a car) has a passenger in front, then if that passenger is identified as a parent/guardian (e.g., based on biometrics or smart card), then he has fewer restrictions, but if that person is not his parents, he will have more restrictions on his telephone functionalities, compared to that of driving alone. In one embodiment, in order to identify the passengers, their mobile devices and their locations are recognized via the local transceivers, the localized unit, and the mobile device(s). Based on the identifications of the mobile devices (e.g., cellular telephone numbers or other identifying features such as SIMS), the identity of the holders are determined. In one embodiment, this method is combined with other identification methods for additional checks.
The rules and restrictions can be updated crossing state lines or boundaries for local governments/cities, downloaded on a kiosks or terminals, remotely, in proximity of the kiosks or terminals (while stopping or moving), by radio signals or magnetic/optical transmission of data (or even cable connections, if the car is stopped to update from those kiosks or terminals). Those rules can also be updated at the yearly inspection stations by the local governments, for all cars.
In one embodiment, the busses and trucks have more restrictions than cars for texting or telephone functions. At dark or night, there are more restrictions than during the daytime. In one embodiment, the family plan for telephone company dictates the rules, or who can change them (rules and restrictions on the usage of phones), with some password or other ID verification techniques. In one embodiment, this system can be integrated with GPS, satellite transmissions, and emergency road services, such as On-Star service. In one embodiment, the settings are done at the factory, based on destination market, according to local rules.
In one embodiment, the following is disabled/enabled/modified, as one feature or combinations:
-
- keyboard,
- text processing unit,
- text display unit,
- text storing unit,
- text receiving,
- text sending,
- voice receiving, and/or
- voice sending.
In one embodiment, the drunk driver detection, already on the market, can be combined with our system, to report sick, drunk, sleeping, or texting driver, based on the breath analysis/chemical analysis, eye patterns, blinking patterns, breathing patterns, and position of the head for the driver, using face analysis and various pattern recognition methods in the market.
In one embodiment, if the driver receives the text, it will automatically go to one of the passengers, or a designated one(s), based on the identity, telephone ID or number, or the position of the passenger in the car, or the combination of the above. These rules can be predetermined, or set real-time, during driving, by one of the passengers, for example.
In one embodiment, the system periodically searches/detects to see if it is within the range or not, to turn it back on again. For example, after disabling the text earlier, when the car is stopped, or the driver or telephone is removed from the car (when the system detects such a status), the system turns on the texting functions back on again, so that the telephone is fully functional again.
In one embodiment, the presence/identity of the user is determined by triangulation from multiple sensors, or multiple directive antennas, or RFIDs, or magnetic tags, or smart phones, or smart cards, or multiple antennas. In one embodiment, the face recognition or conventional feature/pattern recognition techniques are used for identification of all passengers or driver.
In one embodiment, using multiple sensors, detectors, antennas, tags, reflectors, dishes, transmitters, or receivers, at different locations (in the car, boat, airplane, train, or other vehicles, for personal or commercial use), one can determine the locations of the multiple users/phones in a car (for example). The intensity measurement and/or distance measurement are applied here.
In one embodiment, in each region of the car, there is a set of sensors or transmitters, to detect the presence of a passenger on that area or seat. That will give a binary (Yes/No) answer for the “presence” variable for each seat. This way the passengers for each seat are determined locally. In one embodiment, the passengers for each seat are determined globally, from all the sensors in the car, using the distances or ratios, for example, for intensities, to determine who is in what seat, or which seats are unoccupied.
In one embodiment, 2 kinds of triangulation methods are used, each or both together: (1) based on the relative intensities, (2) based on the delays and timings. When one has the extra points of reference (or redundant antennas or detectors/transmitters/receivers or directional antennas or array of antennas), the extra information can be used to interpolate or extrapolate the other data, to check the validity of the other data, or to average the data, to reduce errors or get a better location or relative position information.
In one embodiment, the microprocessor or controller periodically reads the decoded sequence from the receiver/decoder, and compares it with a stored code. If the decoded code matches a predefined correct code, the microprocessor or controller performs one or more of the following operations:
-
- Inhibits the display from displaying any sent texts.
- Inhibits texting operation, by disabling the texting function of the mobile device.
- Sends a signal to SMSC to withhold sending text messages to the mobile device, until further notice, and meanwhile, to store the incoming text messages, as one option, if the user desires.
As soon as the mobile device is out of transmitter range and receiver fails to detect the transmitted signal, the microprocessor or controller resets mobile device's texting operation back to normal.
In one embodiment of the invention, the transmitter encodes a predetermined sequence and transmits it through inductive antenna to transceiver unit located in front of steering wheel of the vehicle, the vehicle ceiling over driver's head, or the dashboard section in front of the driver. As the mobile device comes within the reception range of transceiver, transceiver receives the transmitted signal through inductive antenna, decodes the transmitted sequence in the decoder block, and after verification of the decoded sequence, for example, by comparing with a replica of the sequence in its memory, generates a logic 1 bit, to logically AND it with ignition and not-park signals, to enable a transmitter. The transmitter encodes a second predetermined sequence, different from the first predetermined sequence, and transmits it through inductive antenna block to transceiver. Receiver block in transceiver decodes the second sequence, which in turn is read by microprocessor/controller, to disable the display/keyboard, for the user.
Another embodiment employs BLUETOOTH® (A wireless technology protocol) technology operating either over a dedicated channel or a plurality of channels. A transmitter transmitting a dedicated code is installed, as in previous embodiments above, within the steering wheel of vehicle or in another location in the vehicle, in the close vicinity of the driver's seat. Similar to the previous embodiments, when a mobile phone device comes within the reception range of the BLUETOOTH® (A wireless technology protocol) transmitter, the BLUETOOTH® (A wireless technology protocol) receiver of the mobile phone device receives the transmitted code, decodes it, and subsequent to verification, initiates a command sequence in the microprocessor or controller, to disable texting operation, and in addition, to send a message, through the control channel to SMSC, to store and withhold sending the messages destined for that mobile phone device.
In one embodiment, where the speed information is not directly available from the vehicle, the speed dependent rules related to the feature modification may be applied by directly/indirectly estimating the speed of the vehicle. For example, in one embodiment, a GPS or a triangulation technique is used to estimate the location of the vehicle (e.g., using the mobile device being carries in the vehicle) at various times (e.g., sampled every 10 seconds). The speed of the car and/or the direction (vector) is determined by comparing the consecutive location of the vehicle and elapsed time between their sampling using known methods. In one embodiment, the sampling time is reduced if the speed increases or variation in speed along the consecutive points are beyond a threshold.
As one embodiment,

IF the time is after 9 pm,
THEN the telephone voice function is deactivated;
UNLESS the call comes from the parents cell number or home number.
The Combinational Rules can be any logical combinations, such as the following, as one condition:
((a OR b OR c) AND (d XOR e)),
where a, b, c, d, and e are the statements, such as:
“The road is dark.”
or
“The road is wet.” (e.g., wet and slippery, due to rain)
Federal government rules can be set up to override local rules, and vice versa, according to the laws enforced. Contract-based rules can come directly from a contract, specifying the time of restrictions, the range of restrictions, distances, and other parameters, which is spelled out in a contract between a business owner and the hired drivers for his trucks, as an example.
Emergency condition rules may override all others, in terms of police calling or 911-calls, or any forward calls, showing the Context or Content flag (as a header information) as being the emergency type.
Sensors to measure the temperature and humidity/rain, inside and outside of the car, or current information/forecasts from web sites or weather channel can be fed into the Environment-based module, to find the corresponding rule(s) for that specific weather condition, as an example, and supply that rule(s) to Rule priority and combination logic module, as shown in

In one embodiment, biometrics or other types of identification is used to identify the driver (e.g., by using a finger print scanning device located at or near the steering wheel, ignition button or other controls). Based on the driver's identification, information such as rules/configurations are queried from a database(s) in one embodiment. The associated mobile devices are identified (e.g., by their service carrier and cellular telephone number) based on the driver's identification, e.g., by querying the identification database(s). In one embodiment, the gathered information is provided to an Action Controller module to effectuate modifications on features/functionalities of vehicle and/or the mobile device(s) based-on rules and environmental context.
One can use a separate code for personal identification of the user, as an example. Each telephone can have a universal or a unique code for identification of the telephone. The user code and telephone codes can be added or combined. In one embodiment, the directional antennas are used, for detection of the location of the users or phones. In one embodiment, the messages are re-routed or stored in a remote place. In one embodiment, multiple points/transceivers of the car are used for sending signals, and also multiple points are used for receiving the signals or reflections of the signals. In one embodiment, the software and instructions/codes are stored on a magnetic or storage media, such as hard drive or memory stick, to be run by a computing device or processor, to implement the methods and steps taught in this disclosure.
In one embodiment, the signal or task or message is forwarded to multiple users, who may in the car, or may be outside of the car, away from the driver of the car, e.g. in another car. In one embodiment, for position detection, for user or phone, one can use a beacon using sound, light, or flashing light, or tags using RFID, to find and identify the objects. The range for detection can be expressed as length, e.g. feet or meter, or as voltage or current for the threshold of the detected signal, as detected by the detectors, sensors, or receivers, based on their prior calibrations, so that it can be mapped to corresponding distances, in terms of meter or feet, for the thresholds, for the detection purposes, for users or phones.
In one embodiment, GPS is used to find the relative or absolute positions of objects. In one embodiment, one can turn off or on a device, such as phone or a module in the phone, or with a timer, with delay, or gradually reduce the voltage or current to zero, e.g. using a slide or variable resistor. In one embodiment, the monitoring is done using a continuous or periodic schedule, triggered by a clock, for example, or manually, by a user or third party, so that if the phone is in/out of the range, or crosses the boundaries, it can be detected in its new status and position.
In one embodiment, RF communication is used between components, or any other parts of spectrum. In one embodiment, the restriction on speed of car is applied for the young driver. In one embodiment, the notifications can go from the reverse directions as well, based on teachings above, i.e. from device A to B, as an example, rather than device B to A, as in the teaching above, or going through a proxy, sending a notification to the server or central location, e.g. for status/location of the phone, e.g. notification that if the phone is in the range, or if it is outside the range.
In one embodiment, a time difference between 2 or more reflected signals, with respect to a base time of another signal, e.g. original signal, can be used to find the time delay, or distance differences between different objects, based on the speed of light or sound, as the source, to pinpoint different objects in the car, and find/independently verify the position of users and phones.
In one embodiment, the features to be disabled or modified/limited are speed dependent (i.e. the speed of the vehicle), or based on the age of the driver. In one embodiment, the expiration time or extension time periods for modifying a feature can be speed dependent, for example, for different ranges of speed, different ranges/classes of features are disabled/modified, e.g. for low speed range, sending SMS is disabled, and at higher speed range, receiving SMS is disabled, as well.
In one embodiment, Multimedia messaging service (MMS), movies, video, songs, lectures, books, text, and recorded voices can also be applied to this teaching here. In one embodiment, a computer readable media is used to store the data or executable codes to run the software for the implementation of the methods and steps of this invention.
In one embodiment, when a user plugs the phone to a battery charger at a vehicle, the mobile device recognizes the power plug attachment event and inquiries the user to indicate whether the current location is in a vehicle (on mobile device user interface or on the car user interface, for example), and/or whether the user intends to drive. If the user indicates YES, the mobile device modifies the features, such as disabling SMS and/or a message is sent to SMSC or a remote service to withhold messages and/or calls. In one embodiment, the mobile device user interface does not let the user proceed, until the user answers the inquiry, or the power cord is unplugged.
In one embodiment, once the mobile device receives a message indicating total shut-down from the localized transceiver, it turns itself off, after e.g. verifying the associate ID with the transceiver. For example, this is used in a theater setting, to reduce the unwanted/disturbing calls during presentation.
In one embodiment, instead of the SMS messages at SMSC, the SMS messages are stored on the mobile device, and the response that the user cannot respond in person is sent to the sender. In one embodiment, SMSC sends similar message to the sender, when storing and not forwarding the messages to the mobile device, due to modification of the feature on the mobile device. In one embodiment, the SMSC keeps track of the enablement and modification times of the mobile device and the senders, so that it would send the automatic response to a sender only once, if the feature has not since been enabled. This prevents a possible infinite loop of messages between disabled senders and receivers.
In one embodiment, when the modifying feature is receiving telephone calls, special answering reply is used at the answering service, to indicate to the caller that, e.g. “The callee is currently driving, and cannot accept a phone call.”. In one embodiment, once the mobile device features is being modified, the mobile device (or localized unit) sends a message to a service at the telephone service provider with a code indicating e.g. to modify the reply message, in answering service and/or hold incoming calls and direct them straight to the answering service. In one embodiment, the telephone service sends a message to the mobile device, indicating that a call went straight to the answering service, e.g. indicating to the user with a special audio tone/sound.
In one embodiment, when the modifying feature relates to phone calls or messaging, and a car is equipped with hands-free telephone and messaging features, then messages and/or calls are forwarded to the hands-free device, for example, by forwarding the messages/calls from the service provider/carrier, to the phone number or SIP address or other identifications, associated with the hands-free device.
In one embodiment, when modifying a feature on a mobile device, if a 2nd mobile device is available, the limited functionality is used on the 2nd mobile device, by forwarding calls and/or messages to the 2nd mobile device, directly, from the limited mobile device, e.g. via a communication link, such as BLUETOOTH® (A wireless technology protocol). In one embodiment, when the limitation is lifted, the on-going calls remain connected on the 2nd mobile device, for continuity, by e.g. continue to forward voice data from the 1st mobile device to the 2nd. On the completion of the phone call, the new calls would not be forwarded to the 2nd mobile device. In one embodiment, the limited feature mobile device recognizes other mobile devices, e.g. in a piconet, established via BLUETOOTH® (A wireless technology protocol), and queries a preconfigured list of trusted mobile devices to determine whether the calls or messages can be forwarded to the 2nd mobile device. In one embodiment, there is a priority settings used to determine which mobile device among available ones in the piconet should get the forwarded messages/calls. In one embodiment, the forwarding number/person's name/ID, corresponding to the 2nd mobile phone, is entered/specified on-demand in real-time, by the user or authority, e.g. on 1st mobile device, or from a car/vehicle. In one embodiment, the proximity (the nearest phone to the driver, or the closest passenger detected, for example, based on the RF power level, or based on location determination by other methods, mentioned here in this disclosure) is used to identify/assign the 2nd mobile phone, for this purpose.
In one embodiment, the sound goes from top speakers in the car for telephone voice or music to speakers on the foot-level, underneath, or transfer the sound to speakers on the back seats, to focus/de-focus and alert the user or listener/driver about the telephone, or put more focus on the road, to prevent accidents.
In one embodiment, the smart cards or tags/magnetic IDs are read by a reader, in contact or remotely, to identify the person, or role, e.g. parent, based on a connected database, e.g., to show the relationships between people, e.g. names of children and parents, connected/referred to, in the database, or otherwise, found on the smart cards or tags of the parent or child, e.g. mentioning the ID card or number/code for the other person, i.e. the child or parent, respectively, pointing to the other person, as a method of verification or locating the other person, to activate the rules and proximity conditions, e.g. when the passenger is the parent, and the driver is the kid, in which case some restrictions on the kid is relaxed, or e.g. the calls are forwarded to the parent's phone automatically. In one embodiment, when two cards are in the vicinity of each other, they signal each other, to recognize each other (having antennas, and also power source, at least on one of them), for the conditions mentioned above, to recognize that the parent is sitting next to the kid/driver.
Wherever a vehicle is used in this disclosure, the teaching may be generalized to other enclosures such as train, airplane, boat, metro-rail, bus, trucks, air-borne or sea-borne vessel, or air-traffic controller or un-manned airplane controller seating areas.
The tasks in this disclosure can be implemented/performed by software/hardware/firmware or a combination, in a local, central, or remote location, partially or fully.
This invention can apply to any functions for any mobile device. It does not have to be limited to a vehicle or car. The driver can be generalized as the user. The passenger can be generalized as the 2nd class of users. The parents can be generalized as authority, police, owner, boss, or government.
