Abstract
Based on bounds of a period of reduced operation for a base device, a base device generates a power management message for transmission to a peripheral device. In the power management message, the base device inserts bounds of a period of reduced operation for the peripheral device. As a result, the periods of reduced operation conserve battery power in both devices and the two devices may reestablish a communications channel upon reaching the end of the period of reduced operation and resuming normal operations.
Claims21
A method of managing power at a peripheral device, said method comprising:
- receiving, from a base device, a power management message, said power management message including an indication of bounds of a period of reduced operation for said peripheral device;
- according to said indication:
- reducing operation of said peripheral device at a first time;
- and
- resuming operation of said peripheral device at a second time.
A peripheral device comprising:
- a processor adapted to:
- receive, from a base device, said power management message, said power management message including an indication of bounds of a period of reduced operation for said peripheral device;
- and
- according to said indication:
- reduce operation of said peripheral device at a first time;
- and
- resume operation of said peripheral device at a second time.
A computer readable medium containing computer-executable instructions that, when performed by processor in a peripheral device, cause said processor to:
- receive, from a base device, a power management message, said power management message including an indication of bounds of a period of reduced operation for said peripheral device;
- said instructions causing said processor to, according to said indication:
- reduce operation of said peripheral device at a first time;
- and
- resume operation of said peripheral device at a second time.
