Detecting and characterizing impacts using saturation data of a low-g accelerometer

Abstract

Techniques for detecting and characterizing impacts using saturation data of a low-g accelerometer are disclosed. A system for detecting impacts using a low-g accelerometer includes an accelerometer, one or more memory devices, and a processor. An acceleration measurement of an axis of the accelerometer that indicates that the axis is saturated is obtained. A direction of acceleration in the axis is obtained based on the acceleration measurement. A saturation period for the axis is determined. A determination of whether the saturation period satisfies a duration threshold is made. In response to the saturation period satisfying the duration threshold, an impact is detected and a record of the detected impact based on the direction of acceleration is stored in the one or more memory devices.
