Abstract:
1. A method, comprising: computing a metric based on a multi-axis accelerometer signal to remove an acceleration due to gravity, wherein the multi-axis accelerometer signal comprising a separate, single axis accelerometer signal corresponding to each axis of the accelerometer; setting a bandwidth of a hardware gyroscope filter based on only a subset of the single-axis accelerometer signals and the computed metric; low-pass filtering, by said hardware gyroscope filter, a signal from a multi-axis gyroscope; wherein setting the bandwidth of the hardware gyroscope filter comprises determining whether the only a subset of the single-axis accelerometer signals is less than or greater than threshold; and wherein computing the metric comprises computing at least one of variances of the only a subset of the single-axis accelerometer signals, standard deviations of the only a subset of the single-axis accelerometer signals, and a square root of a value based on the only a subset of the single-axis accelerometer signals less a gravitational constant.
