Abstract:
1. A target device for use in a weapons simulation system including a weapon simulator having a trigger, a firing chamber arranged for firing a blank cartridge responsive to actuation of the trigger, and a transmitter arranged to emit a light signal responsive to actuation of the trigger, the light signal comprising a beam of pulsed light defining one or more activation codes, each of prescribed duration, the target device comprising: a sensor array comprising a plurality of photodiodes arranged to generate respective output signals responsive to light received thereon; a processor associated with the sensor array so as to be arranged to receive the output signals from the photodiodes of the sensor array; the processor being arranged to determine that the sensor array has been hit by the weapon simulator in response to a first portion of one activation code being received by one of the photodiodes and at least one second portion of said activation code being received by different one of the photodiodes in which the first portion and said at least one second portion correspond to an entirety of one activation code and in which the first portion and said at least one second portion are received within the respective prescribed duration; and an output arranged to output a hit signal in response to determination by the processor that the sensor array has been hit by the weapon simulator.
