  • Patent number: 10681668
    Abstract: Methods and apparatuses for device location are described. In one example embodiment, an apparatus and method for determining a location of a mobile device is presented using a single narrowband radio system. In one implementation, Bluetooth is utilized. Using the single base operating with the narrowband radio, the location of the mobile device is found by applying both angle determination and distance determination. Using phased array antennas, the angle between receiver and base is determined. The distance is determined using a time-of-flight method based on phase comparison and phase lock loop techniques which can be applied in narrowband radio transceivers.

  • Patent number: 9844700
    Abstract: An avalanche self-rescue device uses an MEMS accelerometer and possibly a gyroscope in order to determine its orientation relative to the gravitational horizon. Whenever the device is oriented vertically with respect to the gravitational horizon (pointing gravitationally upwardly), a speaker emits a tone to so indicate and possibly a light illuminates in conjunction with the sound output. A different tone and possibly a different light output may be dispensed whenever the accelerometer is not oriented vertically with respect to the gravitational horizon. The device can be a standalone device, incorporated in an item of clothing, safety equipment, etc., or integrated into another electronic device such as a rescue beacon or a cellular phone.

  • Patent number: 9823332
    Abstract: A mobile device includes a chemical sensor to detect chemicals in the environment in which the mobile device is present. The detected chemicals are analyzed and used to generate a chemical characteristic of the environment. The chemical characteristic of the environment is used to determine location related data for the mobile device. For example, an implemented within or remote chemical characteristic database that stores chemical characteristics associated with location related data may be searched based on the chemical characteristic of the environment to determine the location of the mobile device. The location related data may be a location of the mobile device or assistance data that may be used to assist in generating a more accurate position fix, e.g., using a satellite positioning system. The location related data may simply whether the mobile device is inside or outside or the floor of a multi-floor building.

  • Patent number: 7970081
    Abstract: A wireless communication device uses a time-invariant delay-Doppler channel response estimate for received signal demodulation. The device provides coherent signal demodulation by accounting for frequency and time selectivity in a land-based mobile communication environment, which arise mainly because of delay and Doppler shifts, respectively. In one embodiment, the wireless communication device includes a channel estimator that estimates channel response in a wireless communication network by estimating a delay-Doppler response of a wireless communication channel to obtain a delay-Doppler channel response estimate and converting the delay-Doppler channel response estimate to a time-varying channel response estimate, e.g., a time-varying frequency or impulse response. The delay-Doppler response may be estimated in a continuous or discrete domain.

  • Patent number: 7847729
    Abstract: A handheld electronic device, such as a GPS-enabled wireless communications device with an embedded camera, a GPS-enabled camera-phone or a GPS-enabled digital camera, determines whether ephemeris data needs to be obtained for geotagging digital photos taken with the device. By monitoring user activity with respect to the camera, such as activation of the camera, the device can begin pre-acquisition of a GPS position fix by obtaining needed ephemeris data before the photograph is actually taken. This GPS pre-acquisition improves the likelihood that a position fix (GPS lock) is achieved by the time the photo is taken (to enable immediate geotagging). Alternatively, the photo can be geotagged retroactively by appending the current location to the metadata tag associated with the digital photo. An optional acquisition status indicator can be displayed on a user interface of the device to indicate that a position fix is being obtained.

    Abstract: Devices and methods are described for determining position information without broadcast ephemeris data for extended time periods. A server or client device receives or collects historical state data of satellites of a satellite-based positioning system and generates predictions of future satellite trajectories for future time periods. When a server generates the predictions, the predictions are subsequently transferred to a client device. The client device selects predictions appropriate to time of interest. The time can be any time during a period of at least seven calendar days. The client device reconstructs satellite states using information on the predictions and uses the reconstructed satellite states to acquire satellite signals as appropriate to the current location and time of the client device.

  • Patent number: 6657587
    Abstract: A tracking system uses a miniaturized geographic position determination and communications module, preferably in the form of a thin capsule, enabling the enclosure to be hidden in very small spaces, including personal concealment. Electronic circuitry and a thin, rechargeable battery are contained within the enclosure, the circuitry including a global positioning satellite receiver, a communications transceiver, and a controller. The controller causes the global positioning satellite receiver to receive and decode a signal relating to the geographic position of the module; cause the communications transmitter to communicate the geographic position information to a remote location; and disable the global positioning satellite receiver and communications transceiver when not in use so as to conserve power.

    Abstract: A position identification system, that employs satellite navigational or similar positioning technology is provided. In one embodiment, the position identification system includes a receiver for receiving position signals from a positioning system; an orientation device that is configured to rotate about at least one axis; a pointing element coupled to the orientation device to provide indication of a direction to a desired position; and a processor that is coupled to the receiver to receive the position signals. The processor computes a current position of the position identification system based upon the position signals. The processor directs the orientation device, based upon the current position and the desired position, with the pointing device tracking the direction to the desired position as the current position changes. Using the positioning system, a pointing device is used to identify the direction to the desired location to the user of the positioning system.

  • Patent number: 6456931
    Abstract: The present invention provides a computer implemented method and apparatus for providing a directional arrow to intermediate locations to aid a user of a vehicle navigation system. According to one aspect of the present invention, a vehicle navigation system is provided and includes a processor configured to determiner the vehicle location from location data generated by a plurality of sensors. Where the location data does not correspond to map data in a map database, a directional indicator is generated on the display to indicate a first location corresponding to the map data. In one embodiment, the first location corresponds to a road segment in the map database nearest the vehicle location. In another embodiment, the processor is configured to identify an intermediate location on the route and generate a directional indicator on the display which indicates the direction to the intermediate location.

    Abstract: The invention specifies a method for navigating a vehicle, in which a change in the vehicle's direction is ascertained by integration of a signal indicating a speed of change in direction. To this end, the result of the integration is corrected by the following steps: a) The absolute direction of the vehicle at a first instant is determined using external auxiliary means; b) The absolute direction of the vehicle at a second instant is determined using external auxiliary means; c) The difference between the absolute directions is ascertained; and d) The result of the integration is normalized to this difference. The method enables the determination of directions more accurately.
