ABSTRACT:
A paintball gun trigger system includes a trigger, an emitter arranged to emit light and collector arranged to receive an amount of the light that varies with the position of the trigger and produce a signal that varies with the position of the trigger. A controller is arranged to determine from the signal when the trigger has been pulled and released. In one embodiment, the light beam from the emitter is pulsed on and off and the signal from the collector is sampled at regular intervals. Variations in the pulsed collector signal are used to detect when the trigger has moved to a pulled position and a released position, and when the collector is swamped with light from another source.
