SYSTEM AND METHOD FOR SELECTIVELY ACTIVATING A COMMUNICATION DEVICE
First Claim
1. A power management system for an electronic device, comprising:
- a microprocessor controlling said device;
an accelerometer; and
a power application operating on said microprocessor to place said device in one of a plurality of power consumption modes by monitoring signals from said accelerometer and changing modes within said plurality of power consumption modes based on said signals, said power application providing instructions to said microprocessor toplace said device in a higher power state than a low power state when said device is in a stationary state at a resting location and said accelerometer provides a first signal indicating a subsequent movement of said device from said resting location to a first location in a spaced relationship from said resting location and then activate a backlight for said device when placed in said higher power state; and
place said device in said low power state from said higher power state upon receipt of a signal indicating return of said device from said first location to around said resting location, said signal being derived from data from said accelerometer, and then deactivate said backlight.

Abstract
The disclosure provides a system and method for detecting activation of a communication device via passive means, For the system and method, the device comprises a casing for housing a display and a keyboard; a microprocessor controlling aspects of the keyboard and display; a passive usage sensor; and a power application operating on the microprocessor. The power application monitors the usage sensor for a signal indicating movement of the device from a resting location when the device is in a low power mode and upon detection of the signal for provides power to at least one additional element in the device.

9. A method of selectively placing an electronic device in one of a plurality of power consumption modes, comprising:
-
monitoring a sensor in said device for a first signal indicating movement of said device from a resting location when said device is operating in both a low power state and a stationary state; placing said device in a higher power state from said low power state when said device is stationary and said sensor provides a first signal indicating subsequent movement of said device and then activating a backlight for said device when said device is in said higher power state; and placing said device in said low power state from said higher power state upon receipt of a signal from said sensor indicating return of said device at or near said resting location and deactivating said backlight. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
