A cordless mouse with an upper and lower housing. The lower housing includes a hole for receiving a ball which extends through the hole in the bottom of the mouse. The upper housing is uniquely provided with a cavity for receiving a battery, with a portion of the cavity extending over the ball.

Mouse with battery compartment on top

A method and apparatus for establishing a standardized communications protocol for wireless communications between a host and one or more peripheral devices such as joysticks, mice, gamepads, remote controllers or other devices including establishing a standard message format for messages communicated between a host and the peripheral devices, establishing a plurality of unique data types for associated peripheral devices, and prioritizing communications between the host and such peripherals to permit rapid and effective communication therebetween.

Wireless peripheral interface

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 from two RF peripherals, while filtering out other stray RF peripherals operating in the same transmission zone. This allows a user to use the same receiver for one peripheral, such as a mouse, for detailed work and another peripheral for other types of special applications, such as a pointing device for software presentations. The present invention further provides for a power consumption minimization method in the wireless peripheral.
