Abstract
A wireless pointing device includes a push button switch, an optical sensor circuit, and a processor. The processor is configured to transmit to the optical sensor circuit a logic high signal in response to depression of the push button switch for a period greater than or equal to the predetermined first period of time and to transmit a logic low signal in response to depression of the push button switch for a period less than the predetermined first period. The optical sensor circuit responds to the logic high signal by entering a power saving mode wherein an optical sensor in the optical sensor circuit is decoupled from a power source.
