    摘要： Methods and apparatus are described herein for calibration and correction of non-constant sensor errors, and in particular non-constant compass errors, that are based in part on changing software and hardware modes of a host device. The non-constant errors induced in the sensor by each mode and combination of modes is determined in a calibration that may be determined during pre-production testing of one or more host devices. The calibration results can be incorporated into software and/or hardware of the host device. During normal operation, a sensor correction can be applied to sensor measurements based in part on the active mode or combination of modes.

    摘要： A multi-dimensional sensor, a magnetometer or accelerometer, is calibrated based on the raw data provided by the sensor. Raw data is collected and may be used to generate ellipse or ellipsoid parameters, for a two-dimensional or three-dimensional sensor, respectively. An offset calibration factor is calculated based on the raw data, e.g., the determined ellipse or ellipsoid parameters. A sensitivity calibration factor is then calculated based on the offset calibration factor and the raw data. A non-orthogonality calibration factor can then be calculated based on the calculated offset and sensitivity calibration factors. Using the offset, sensitivity and non-orthogonality calibration factors, the raw data can be corrected to produce calibrated data.

    摘要： A homography between two captured images of a planar object is decomposed into at least one possible solution, and typically at least two ambiguous solutions. The ambiguity between the two solutions is removed, or a single solution validated, using measurements from orientation sensors. The measurements from orientation sensors may be used by comparing at least one of the yaw, pitch, and/or roll angles derived from a relative rotation matrix for the one or more solutions to a corresponding at least one of the yaw, pitch, and/or roll angles derived from the measurements from the orientation sensors.

    摘要： A mobile station determines its position using measured parameters of a wireless signal to improve a satellite positioning system (SPS) enhanced dead reckoning based position estimate. The mobile station uses SPS enhanced dead reckoning to estimate a current position. The mobile station receives wireless signals and measures, e.g., received signal strength and/or round trip time, which is compared to a database to derive a wireless signal based position estimate. The SPS enhanced dead reckoning position estimate and the wireless signal based position estimate may then be fused using corresponding confidence levels. The database may be generated and stored in the mobile station. In another embodiment, the database is generated and stored on an online server that may be accessed by mobile stations.

    摘要： Techniques for using measurements made by UEs to improve network performance are described. In one aspect, RF parameters of cells may be determined by taking into account mobility of the UEs. Mobility information for the UEs may be determined based on measurement report messages (MRMs) sent by these UEs for handover. RF parameters such as antenna down-tilt, antenna orientation, antenna pattern, and/or pilot power of the cells may be determined based on the mobility information for the UEs. In another aspect, the RF parameters of cells may be dynamically adjusted based on loading conditions of cells. In yet another aspect, the location of a UE may be determined based on an MRM sent by the UE for handover. The MRM may include timing measurements for multiple cells. The location of the UE may be determined based on the timing measurements.
