Abstract: A method and system for identifying an object in one space monitored by at least one radar transceiver. The method comprises storing intervals of critical distance values (10) associated with the position of a fixed object upon which a time-varying radio signal shadow may be generated, which may be confused with a moving object. Through successive radar detections, the signals are processed and generate a measurement range profile (40), from which a background range profile (41) is extracted to obtain an object range profile (50). The distance of a possible detected object (60) is determined from the analysis of the object range profile. If the distance of the object (4) is external to the critical intervals (51), the object is classified as valid (55). If the distance is internal to the intervals, the detected object may be a shadow and unless further checks are performed, its presence is not indicated.
Abstract: Context sensitive communication augmentation is disclosed. A user equipment (UE) can receive a trigger related to determining a context of a UE. The trigger can be manual, automatic, or remote. In response to receiving the trigger, the context of the UE can be determined based on sensor data. The sensor data can be received from a sensor of the UE or another sensor. Based on the context of the UE, a metric related to a communication modality of the UE can be determined. The metric can be communicated to another device. Information related to the context of the UE, including location information, can be communicated to the other device. A communication modality can be selected based on the metric relate to the UE and communication modalities of the other device. The metric can be updated based on changes in the context of the UE, allowing for updating the communication modality.
Abstract: Systems, methods, and computer program products for transmitting data between devices are disclosed. A device may utilize a standardized communication system (“SCS”) to transmit data directly between devices including an SCS. The SCS may discover available devices. The SCS may determine available transmission paths between a first device and a second device. The SCS may select a transmission path between the first device and the second device, and the SCS may transmit data from the first device to the second device using a standardized communication protocol (“SCP”). The first device may transmit a message to the second device. The first device may edit the message after the transmitting. The second device may delete the original message. The second device may store the edited message.
Abstract: An axial displacement judgment device has a first detector acquiring a first detection value from a G sensor which detects an acceleration applied to a radar device, a second detector acquiring a second detection value from a YG sensor which detects the acceleration applied to a vehicle body, and a difference calculator calculating a detection difference value, which is a difference between the first detection value and the second detection value, every first period. The device further has an average difference value calculator calculating an average difference value as an average value of the detection difference values calculated during an acquisition period including the first periods, a deviation calculator calculating a difference standard deviation of the detection difference values calculated during the acquisition period, and a judgment section detecting occurrence of an axial displacement of the radar device based on the average difference value and the difference standard deviation.
Abstract: Method, systems, and computer-readable media for receiving, from an application instance operating on a client device, information that indicates a client device identifier, a wireless proximity beacon identifier, and a proximity of the identified client device to the identified wireless proximity beacon. From the received information, a determination is made whether the proximity of the identified client device to the identified wireless proximity beacon satisfies a threshold proximity. Based at least on the determination, an action is determined that the application instance operating on the identified client device is permitted to perform while the proximity of the identified client device to the identified wireless proximity beacon satisfies the threshold proximity. Information is transmitted to the identified client device that enables the application instance operating on the identified client device to perform the action.

Abstract: A method and system of reliably detecting a reactive jamming attack and estimating the jammer's listening interval for exploitation by a communication system comprises channelizing one or more signals of interest (SOI), channelizing one or more signals of unknown origin (SUO), identifying frequency support patterns for the SOI and SUO using Bayes thresholds, comparing SOI and SUO detection map histories, and determining a percent match, where a match percentage above a specified minimum indicates a reactive attack. Edge detection can be used to enhance jammer support. Embodiments further detect reactive jammer adaptation to changes in the SOI's frequency support. Embodiments include detectors that are insensitive to jammer modulation and/or signal type. A jammer reaction delay and/or size and periodicity of receive window can be detected. Embodiments determine if a jammer is copying and retransmitting the SOI's waveform(s), and/or if the jammer is anticipatory.

Abstract: Generating signals from non-GNSS transmitters, and processing the signals using a GNSS positioning module. Systems and methods identify a chipping rate, identify a PN code length, generate a PN code that has a length equal to the identified PN code length, generate a positioning signal using the identified chipping rate and the generated PN code, and transmit the positioning signal from the transmitter. The PN code length may produce, at the identified chipping rate, a PN code duration that is equal to or is a multiple of a PN code duration used in a GNSS system, the identified chipping rate may be equal to or a multiple of a chipping rate used in a GNSS system, and the identified PN code length may be equal to or a multiple of a PN code length used in a GNSS system.

Abstract: A method for ascertaining a useful width of a segment of a street, including traveling the street in a first direction of travel and ascertaining of parking spaces on the basis of echo profiles of an ascertaining device situated in an ascertaining vehicle; ascertaining of lateral distances between the ascertaining device and parked vehicles at both sides of the street, at least one ascertaining of parking spaces and lateral distances being carried out to the right of the ascertaining vehicle, and at least one ascertaining of the parking spaces and lateral distances being carried out to the left of the ascertaining vehicle; and ascertaining of the useful width from the ascertained lateral distances.
Abstract: The invention is directed to a wireless communication device that includes: a radio unit for performing wireless communications with at least one external device; at least one battery for supplying power to the wireless communication device; and at least one processing unit for controlling the radio unit, wherein the at least one processing unit, includes: host processing unit configured to control execution of one or more active state operations; and a secondary processing unit, coupled to the host processing unit and the radio unit, configured to control execution of one or more low-priority operations while the host processing unit is powered down, wherein the secondary processing unit is further configured to determine if an active-state operation is pending, and if it is determined that an active state operation is pending, to power up the host processing unit to control execution of the active state operation.
Abstract: A mobile phone (mobile electronic device) includes an acceleration sensor that detects an acceleration, a communication module that performs communication, and a controller. When the number of steps based on the acceleration detected by the acceleration sensor has reached a first step count during an ON-state of the communication function of the communication module, the mobile phone shifts from a stop state to a walking state. The controller maintains the ON-state of the communication function of the communication module when the mobile phone shifts from the stop state to the walking state. The controller turns OFF the communication function of the communication module when the number of steps based on the acceleration has reached a second step count larger than the first step count.
