METHOD FOR REDUCING POWER CONSUMPTION AND SENSOR MANAGEMENT SYSTEM FOR THE SAME
First Claim
1. A method of reducing power consumption of an electronic device, the electronic device including a plurality of sensors, the method comprising the steps of:
- receiving sensed information from the sensors within a predetermined time period;
judging whether the electronic device is under a stationary state within the predetermined time period according to whether a data variation of the sensed information received within the predetermined time period exceeds a preset error value; and
if yes, controlling a portion of the sensors to enter into a sleeping state or a low-power consumption state.

Abstract
A method of reducing power consumption of an electronic device, the electronic device including a plurality of sensors, the method comprising the steps of: receiving sensed information from the sensors within a predetermined time period; judging whether the electronic device is under a stationary state within a predetermined time period according to a data variation of the sensed information received within the predetermined time period; and controlling a portion of the sensors to enter into a sleeping state or a low-power consumption state when the electronic device is under the stationary state within the predetermined time period.
