Patent ID: 7321755

Claim:
A system for managing power in a wireless interface system that services communications between a wirelessly enabled host and at least one user input device, comprising: a wireless interface unit that wirelessly interfaces with the wirelessly enabled host, wherein the wireless interface unit comprises: an analog module including a transceiver unit, a baseband core digital module further comprising: a transceiver operation detector operable to detect operation of the transceiver unit, and a voltage regulator control signal generator operable to generate a voltage regulator reference control signal corresponding to the operational status of the transceiver; a clock generator operable to generate first and second clock signals corresponding to a first operating state wherein the transceiver is operational and a second operating state wherein the transceiver is turned off; a processing unit operably coupled to the wireless interface unit, said processing unit operable to use said reference control signal to generate a low power mode signal; and a power management unit operably coupled to the wireless interface unit, the processing unit, and the clock generator, wherein the power management unit is operable to receive said low power mode signal and to control the power consumption of the wireless interface unit by providing a first power level to the clock generator when low power mode signal is in a first state and providing a second power level to the clock generator when the low power mode signal is in a second state.
