Abstract
The present invention provides a wireless radio frequency ("RF") communications interface between peripherals and the host personal computer or workstation. In one embodiment, the present invention provides a wireless electronic mouse which uses an RF transmitter to transmit information unidirectionally to a receiver which is coupled to a host computer. This arrangement eliminates the need for a cable connection between the mouse and the receiver, while at the same time permitting continuous communication therebetween. The present invention also provides a method and apparatus to allow the receiver to differentiate between multiple RF wireless mice operating within the same transmission zone by a combination of providing a unique identification code to each transmitting mouse and allowing the user to choose from a plurality of transmission channels. The receiver then automatically switches to the channel selected by the user. The present invention can further receive transmissions from either one or two peripheral devices. In one device mode, the receiver filters out stray frequencies from other RF peripherals. In two device mode, the receiver has the ability to receive information…
