Wireless mouse
First Claim
1. A communication system for receiving signals representing displacement action of a peripheral device comprising:
- a first peripheral device, havinga first non-volatile memory device for storing a first identifier;
a first signal generator for generating a first displacement signal based upon a displacement action of said first peripheral device and for generating a first identification signal; and
a first transmitter, coupled to said first signal generator, for transmitting a first electromagnetic data signal, said first electromagnetic data signal having said first identification signal and said first displacement signal; and
a receiving unit having;
a second non-volatile memory device;
a signal receiver, for receiving said electromagnetic data signal; and
a processor, disposed to receive said first electromagnetic data signal from said signal receiver, for locking said first peripheral device with said receiving unit when said receiving unit is in a lock-on mode to identify said first identifier as a first of one or more authorized peripherals, and storing a signal representing said first identifier in said second non-volatile memory device, and for processing electromagnetic data signals transmitted only from said authorized peripherals.

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 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.

17. A method for locking a first peripheral device, having a first identifier, to a receiving unit and for receiving signals representing displacement action of the first peripheral device, the method comprising the steps of:
-
generating a first identification signal by the first peripheral device; transmitting a first signal representing said first identification signal from said first peripheral device; receiving said first signal by said receiving unit; identifying said first identifier as representing said first peripheral, and storing a signal representing said first identifier in a first non-volatile memory device of said receiving unit if said receiving unit is in a lock-on mode to identify said first peripheral as a first of one or more authorized peripherals; and processing signals transmitted only from said one or more of said authorized peripherals. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
