     * streams data when the device is in motion, and stops streaming data

     * when the device is stationary.

     * Generally this kind of sensor would consume less power than the generic

     * accelerometer sensor, and hence can be used in applications that do not

     * require accelerometer streaming when device is stationary, such as the

     * screen auto-rotation.
