Abstract: A method includes generating motion data by receiving a gyroscope data from a gyroscope sensor, performing integration using the gyroscope data and generating an integrated gyroscope data using a first processor. The method further includes receiving a data from one or more sensors, other than the gyroscope sensor, and performing sensor fusion using the integrated gyroscope data and the data to generate motion data using a second processor.

Abstract: In a method of sensor output configuration, sensor output specifications for a plurality of sensor clients of a sensor are acquired. A first sensor output specification for a first of the sensor clients defines a first value for a sensor parameter. A second sensor output specification for a second of the sensor clients defines a second value for the sensor parameter. The first value and the second value are different. A sensor processing unit, which includes the sensor, is configured based on the sensor output specifications to: simultaneously provide an output of the sensor to the sensor clients according to the first value while a first operational condition is met; and simultaneously provide the output of the sensor to the sensor clients according to the second value while a second operational condition is met, wherein the first operational condition and the second operational condition are different.

Abstract: Systems and methods are disclosed for characterizing motion of a device by taking the difference between pairs of sensor signal samples and comparing an expected higher order moment for the differences determined from an observed first order moment for the differences and/or an observed second order moment for the differences and the observed higher order moment for the differences. A determination of whether the device is experiencing motion may be made based on a comparison of the difference of the moments to a threshold.

Abstract: In a method of inferring ambient atmospheric temperature, an acoustic signal is emitted from a speaker. A first sample of the acoustic signal is captured with a first microphone spaced a first distance from the speaker. A second sample of the acoustic signal is captured with a second microphone spaced a second distance from the speaker. The second distance is greater than the first distance, and a difference between the first distance and the second distance is a known third distance. A time delay in the acoustic signal is determined between the first sample and the second sample. An ambient temperature of the atmosphere through which the acoustic signal traveled is inferred based on a relationship between the time delay and temperature for the acoustic signal over the third distance.
