  • Patent number: 6571299
    Abstract: A wireless, remote, programmable keyboard input system for computers is provided. A single receiver is capable of simultaneous receipt of RF ID-Code transmissions from multiple remote transmitters, is plugged into the keyboard port of the central processing unit of a computer. The computer's standard keyboard is then plugged into the receiver and remains fully functional. The RF ID-Code of each button of each remote hand held transmitter is a unique fixed code. The receiver in this system is programmed by associating, in the receiver's memory, a unique transmitter button ID-Code with the scancode or modified scancode of a key or modified key from the standard keyboard of the computer. When the receiver, in the operation mode, recognizes that RF ID-Code from that transmitter button, it pulls the associated scancode or modified scancode from its memory and sends it off to the CPU of the computer.
