    Abstract: 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.

    Abstract: Aspects of the disclosure relate to computing device technologies, such as systems, methods, apparatuses, and computer-readable media for improving orientation data. In some embodiments, a magnetic vector filter receives magnetometer data from a magnetometer and gyroscope data from a gyroscope and determines the magnetic vector. In another embodiment, a gravity vector filter receives accelerometer data and gyroscope data and determines the gravity vector. Further techniques are described for adjusting filter parameters, based at least in part on the detected change in the variability of the first signal parameter. Furthermore, orientation may be synchronized to a common sensor input, such as a gyroscope.

    Abstract: 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.

    Abstract: Systems and methods are described for operating motion sensors in a power-efficient manner. An example technique described herein includes obtaining, at a motion sensor, first indications of sensed motion of a device associated with the motion sensor; integrating, at the motion sensor, the first indications of the sensed motion to obtain integrated motion information; generating, at the motion sensor, second indications of the integrated motion information; and sampling, at a processor disparate from the motion sensor, selective ones of the second indications. Another example technique includes obtaining a first indication of a motion state anomaly associated with motion of a mobile device and causing a gyroscope associated with the mobile device to transition between a first operating mode and a second operating mode in response to the first indication, where the first operating mode is a reduced-power mode compared to the second operating mode.
