Patent ID: 8145931

Claim:
An imaging device, comprising: at least one interface; and a processor communicatively coupled with the interface, wherein under control of the processor the imaging device compiles over multiple weeks for each of a plurality of discrete time slices each bounded by a particular start and end time on a particular day of the week usage statistics for the time slice based on jobs received on the interface during the time slice, selects a power save entry timeout value and a power save exit timeout value for each time slice based on the usage statistics compiled for the time slice, initiates a power saving sequence during each time slice based on the power save entry timeout value selected for the time slice, initiates a wakeup sequence during each time slice based on the power save exit timeout value selected for the time slice and automatically combines at least two consecutive ones of the time slices into a larger time slice in response to determining that differences in the usage statistics compiled for the consecutive time slices are statistically insignificant, whereupon the larger time slice replaces the consecutive time slices in the plurality of discrete time slices for which power save entry timeout values and power save exit timeout values are selected.
