System and method for conserving power for devices
First Claim
1. A device comprising:
- a sensor that senses movement of the device and outputting a sense signal in response to the movement;
a motion detect circuit coupled to the output of the sensor, the motion detect circuit receiving the sense signal from the sensor and outputting a power enable signal if the sense signal exceeds a threshold value;
a power management circuit coupled to the motion detect circuit, the power management circuit receiving the power enable signal from the motion detect circuit (420) and outputting a power signal to initiate a power up mode as a result of receiving the power enable signal; and
a processing circuit, coupled to the power management circuit and the sensor, the processing circuit, the processing circuit receiving the power signal along with receiving and processing the sense signal,wherein the sense signal, in response to movement, first, initiates the power up mode and, second, provides an input that defines a specific command for a graphic user interface.

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 (404) 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.
