Wireless mouse apparatus
First Claim
1. In a computer system comprising a computer having a keyboard and a display device connected to the computer, an improved position indicator means comprising:
- a mouse having means responsive to movement thereof over a support surface for generating electrical signals indicating the position of the mouse;
power source means carried by the mouse;
circuit means, including a selectable frequency-setting means, carried by the mouse and powered by said power source means for generating frequency modulated radio signals corresponding to said electrical signals;
an antenna within said mouse for transmitting said generated radio signals; and
processing means associated with said computer for receiving the transmitted radio signal and converting said radio signal into a display on said display device, said power source, circuit means, and antenna being cooperatively arranged to provide a transmitting output sufficient to effectively transmit said signals to said processing means to cause said display to be accurately positioned on said display device corresponding to the positioning of said mouse notwithstanding changes in the directional positioning and noncontinuity in the line-of-sight path between said antenna and the processing means.
