  • Patent number: 5999799
    Abstract: A method and apparatus for preventing the loss of a remote control input device used with a stationary device provides the stationary device with a transmitter and a signal generator that generates signals transmitted by the transmitter. The remote control input device communicates wirelessly with the stationary device, and has a wireless signal receiver that receives the signals from the signal generator, and a distance warning circuit. A distance warning output signal is produced by the distance warning circuit when the input device is beyond a specified distance from the stationary device, as a function of the signals received by the wireless signal receiver. The remote control input device also has an indicator that produces a human-perceptible distance warning signal in response to the production of the distance warning output signal by the distance warning circuit.
