SYSTEM AND METHOD FOR BATTERY CONSERVATION IN A PORTABLE DEVICE

摘要

A hand-held device, such as a remote control, has a time-limited feature, such as backlight illumination, that is caused to be activated upon the occurrence of a triggering event sensed by a triggering sensor, such as a motion sensor. The hand-held device functions to disable and/or downwardly adjust a time period during which the time-limited feature will be allowed to be active upon a future occurrence of a triggering event in response to the device determining that a predetermined number of trigger events sensed via the triggering sensor are false trigger events. The time-limited feature may be disabled by disabling the triggering sensor.
