Abstract

Apparatus for generating a pulsed triggering signal for use with a computer game system including a joystick. The apparatus includes a detection unit for detecting a coordinate signal between a joystick output port and a game input port of a computer, and a pulse generation unit for generating a pulsed triggering signal responsive to the detected coordinate signal.

Claims

1. Apparatus for generating a pulsed triggering signal for use with a computer game system including a joystick, said apparatus comprising detection means for detecting a coordinate signal between a joystick output port and a game input port of a computer, and pulse generation means for generating a pulsed triggering signal responsive to said detected coordinate signal.

2. An apparatus as claimed in claim 1, wherein said pulse generation means includes pulse shaping means for generating a pulsed signal responsive to said coordinate signal, and frequency divider means for dividing the frequency of said generated pulsed signal and for producing said pulsed triggering signal.

3. An apparatus as claimed in claim 1, wherein said apparatus further includes filtering means for filtering said coordinate signal and producing a coordinate activity indicator signal representative of whether the coordinate signal is active.

4. An apparatus as claimed in claim 3, wherein said apparatus further includes supplemental oscillator means for providing an oscillating signal.

5. An apparatus as claimed in claim 3, wherein said apparatus further includes selection means for selecting either said pulsed triggering signal or said oscillating signal as the pulsed triggering signal responsive to said coordinate activity indicator signal.

6. An apparatus as claimed in claim 1, wherein said apparatus further includes a plurality of detection means for detecting a plurality of coordinate signals between a joystick output port and a game input port of a computer, and a plurality of pulse generation means for generating a plurality of pulsed triggering signals responsive to said detected coordinate signals.

7. An apparatus as claimed in claim 6, wherein said apparatus further includes selection means for selecting between said plurality of pulsed triggering signals responsive to said coordinate signals.
