1. A remote control for use with an apparatus for positioning a cursor on a monitor screen in which the apparatus includes a plurality of radiation detectors and a mechanism that determines a position at which to place the cursor by comparing signals from the detectors;

  • said remote control comprising;

    a user operable switch having first and second states;

    a signal generator that produces an alternating signal which alternates at a given frequency;

    a first means for producing a first signal formed by pulses of the alternating signal which pulses of the first signal occur at a first rate;

    a second means for producing a second signal formed by pulses of the alternating signal which pulses of the second signal occur at a second rate; and

    a radiation emitter connected to said first and second means for producing signals, said emitter producing a beam of radiation which is modulated by the first signal in response to said switch being in the first state, and producing a beam of radiation which is modulated by the second signal in response to said switch being in the second state.
