Title:
POWER SAVING SCHEDULER FOR TIMED EVENTS
Document Type and Number:
WIPO Patent Application WO/2009/148472
Kind Code:
A3
Abstract:
The disclosed system and methods include a power saving scheduler (40) that maintains timed events in an event table (42). Each timed event has an associated tolerance period within which the event should begin execution following a trigger, and a timestamp indicating a scheduled execution time for the event. When a device (10) is in a low-power sleep mode, a trigger may wake up the device to a wake state. The power saving scheduler then accesses the event table of upcoming timed events, and reorders the event table from the event having the shortest tolerance period to the event having the longest tolerance period. Each event for which the timestamp is within the tolerance period as measured from the trigger time is executed. After a plurality of such events is executed, the device may return to the sleep mode.
