Abstract: Aspects of the invention are related to a method for synchronizing a first sensor clock of a first sensor. The exemplary method comprises: correcting the first sensor clock for a first time, transferring data from the first sensor, and correcting the first sensor clock for a second time, wherein a time interval between two corrections of the first sensor clock is selected such that the first sensor clock is sufficiently aligned with a processor clock of a processor over the time interval.

Abstract: Techniques for compensating for inertial and/or magnetic interference in a mobile device are provided. The mobile device can include a vibration motor to vibrate the device, a processor, and can include an inertial sensor and/or a magnetometer. The processor can be configured to actuate the vibration motor to induce vibration of the mobile device, to measure motion of the mobile device with the inertial sensor of the device to produce sensor output data and/or to measure a magnetic field generated by the vibration motor to produce magnetometer output data, and to compensate for the vibration of the inertial sensor induced by the vibration motor to produce compensated sensor output data and/or to compensate for a magnetic field generated by the vibration motor when the vibration motor is actuated to produce compensated magnetometer output data.

Abstract: Systems, apparatus and methods for populating and using a pressure database to determine an altitude of a unit with an unknown altitude are presented. A pressure from one or more barometric pressure sensors linked to respective base stations are interpolated to determine a reference pressure (e.g., at sea level) at arbitrary coordinates (x,y) having pressure reading. For example, a mobile station at the arbitrary coordinates (x,y) records a pressure at the mobile station. A difference between this pressure at the mobile station and the interpolated reference pressure is determined, which may directly be interpreted as a defined altitude of the mobile station.

Abstract: A method of controlling power consumption of a voice activation system in a mobile platform includes monitoring one or more sensors of the mobile platform. Next, it is determined whether a microphone of the mobile platform is concealed or obstructed in response to the monitoring of the one or more sensors. If so, the mobile platform transitions one or more components of the voice activation system from a normal power consumption power state to a low power consumption state.

Abstract: Disclosed embodiments pertain to the measurement of heart rate in the presence of motion and noise. Spectral peaks in measurements by an optical sensor are compared with spectral peaks obtained from a motion sensor signal measurements, to obtain a fundamental frequency in the optical sensor signal, where the fundamental frequency is associated with a user's heart rate. A first heart rate may be estimated based on the fundamental frequency. A variety of quality metrics may be determined for the first heart rate estimate. A second estimated heart rate may be determined based by processing a frequency domain representation of the optical sensor signal based on a frequency domain representation of the motion sensor signal. One or more of the previously determined quality metrics may be dynamically adjusted based on a comparison of first and second estimated heart rates.

Abstract: Disclosed is an apparatus and method for classifying a motion state of a mobile device comprising: determining a first motion state associated with a highest probability value and with a first confidence level greater than a first threshold; entering the first motion state; while the first motion state is active, determining a second motion state associated with a highest probability value and with a second confidence level greater than the first threshold, the second motion state being different from the first motion state; determining whether the second motion state is to be entered; and in response to determining that the second motion state is to be entered, entering the second motion state.
