US Patent 7725094 Power prioritization among functions of a multi-function device

A device can provide a first function and a second function. The first function can have a higher priority for power than the second function. An input element can receive an indication of a remaining capacity of a power source for the device. A comparison element can compare the indication of the remaining capacity of the power source to a power threshold associated with the second function. A control element can initiate a power control action with respect to the second function if the indication of the remaining capacity of the power source is below the power threshold.
