Abstract
A power conservation circuit for a hand-held motion-sensing device and a method for conserving power on such devices are provided. The present disclosure provides for sensing the movement of device by a sensor and outputting a sense signal in response to the movement, processing the sense signal output of the sensor by a processing circuit, selectively enabling and disabling power to the processing circuit () by a power management circuit and providing a signal by a motion detect circuit to the power management circuit for enabling power to the processing circuit based on the sense signal from the sensor. The motion detect circuit differentiates the sense signal from the sensor and provides a power enable signal to the power management circuit if the differentiated sense signal exceeds a signal threshold.
