Abstract

A simulated fire and hit indicator apparatus and method includes two opponent stations having a gun device and a target device and a master control unit. Each gun device generates a dispersed trigger-active signal and a focused bullet signal; preferably in the form of a modulated pulse burst powering infrared emitters. Detectors, preferably in the form of phototransistors, are mounted in each target to sense the bullet signals and each operates to produce a hit signal when struck by an opponent's bullet signal. The trigger-active signals are detected, again preferably by phototransistors, and produce fire signals corresponding to respective gun devices. Each station includes processing circuitry to produce uniform pulse bursts representative of the fire and hit signals of the station, and the signals may be mixed and may be used to enable a radio transmitter that broadcasts the fire and hit data to a receiver on the master control. The master control includes decoding circuits to separate the data into component signals corresponding to the fire and hit status of each station. The master control outputs all fire data, but includes logic circuits that prohibit output of a later received hit signal and implements output for an earlier received hit signal. Accordingly, the method comprises the production and processing of these various signals.
