Scoring system for shooting gallery
First Claim
1. A scoring method for determining which one of several guns has been fired, and for determining which one, if any, of several targets has been struck by the fired gun, comprising the steps of:
- sensing in chronological order the identities of successively triggered guns;
generating each time a gun is triggered a FIRE signal associated with the gun triggered, the FIRE signal having a preset duration and being initiated when the gun is triggered, unless the immediately preceeding FIRE signal is still present, in which case initiation of the later FIRE signal is delayed until termination of the earlier FIRE signal, the triggered gun being fired upon initiation of the later FIRE signal;
sampling the targets, starting the sampling a preset time after initiation of each FIRE signal and continuing until a struck target has been found or until all of the targets have been sampled;
sensing the identity of the struck target; and
,associating the identity of the struck target with the identity of the gun associated with the current FIRE signal.

Abstract
An electronic system especially advantageous for use in a shooting gallery of the type in which the guns project beams of light instead of bullets employs an electronically gated target polling systems to enable each fired gun to be credited unambiguously with a score based on which target, if any, is struck by the gun fired. All the photosensors on the targets are polled during a particular very short time interval after any of the guns has been triggered; extraneous light occurring at other times is not registered. When a gun is fired, the system initiates generation of cosmetic action such as recoil, simulated explosion, and ricochet sound, and the system decrements a rounds remaining counter. When a target hit is registered, the system initiates target effects, and increments a score counter associated with the gun fired by a target-dependent amount. A large number of guns and targets can be accommodated.
