Abstract: A system and method for efficiently determining trajectory and/or location of a device (or user thereof). In a non-limiting example, rotation matrix coefficients may be analyzed in conjunction with stepping information to determine device trajectory and/or location. The system and method may, for example, be implemented in a MEMS sensor system, for example comprising a MEMS gyroscope, MEMS accelerometer, MEMS compass and/or MEMS pressure sensor.

Abstract: A sensor may be automatically calibrated during manufacture by providing a sensor processing unit having an integrated sensor, performing a check to determine if the integrated sensor has been previously calibrated upon a reset. When it has been determined the integrated sensor has not been previously calibrated, an automated calibration pattern may be imparted to the sensor so that a calibration parameter is determined.

Abstract: In a method of motion sensor calibration, a motion with which to calibrate a motion sensor is determined. The motion sensor is controlled by a sensor processor and the motion sensor is comprised within a user interface that is coupled with a gaming engine. The sensor processor and the gaming engine coordinate regarding the motion. The sensor processor monitors the motion sensor for evidence of the motion made as a user input via the user interface in response to game content implemented by the gaming engine, based on the coordination, to incite the motion. The sensor processor calibrates the motion sensor with the motion.

Abstract: A system and method for classifying a position of a device may include processing one or more respective signal characteristics of one or more signals indicative of device orientation to determine a position of a device relative to a user. In a non-limiting example, various aspects of this disclosure include analyzing, over time, one or more characteristics of a first signal indicative of the alignment of a first device axis with a reference direction and one or more characteristics of a second signal indicative of the alignment of a second device axis with the known direction, and determining the position of the device based at least in part on such analysis. One or more analyzed signals may, for example, correspond to and/or be derived from MEMS sensor signals.

Abstract: Systems and devices are disclosed for communicating between a portable device and a first base station. A wireless communications link may be established between the portable device and the first base station. Sensor data indicative of motion of the portable device relative to the first base station may be obtained, such that communication parameters may be adjusted based at least in part on the motion sensor data.
