Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
82 words
Apparatus for controlling the individual firing of a number of pyrotechnic devices for simulating the effect of gun fire on a target, comprising: sensing means mounted to said target for generating a signal in response to a hit on said target; means for detonating said pyrotechnic devices; control means responsive to said sensing means for actuating said means for detonating, said control means including means actuated by successive signals from said sensing means for controlling the detonation of respective individual pyrotechnic devices.
Claim 2
Dependent Claim
82 words
Apparatus for controlling the individual firing of a number of pyrotechnic devices for simulating the effect of gun fire on a target, comprising: sensing means mounted to said target for generating a signal in response to a hit on said target; means for detonating said pyrotechnic devices; control means responsive to said sensing means for actuating said means for detonating, said control means including means actuated by successive signals from said sensing means for controlling the detonation of respective individual pyrotechnic devices.
Claim 3
Dependent Claim
65 words
Apparatus as in claim 1 wherein said means actuated by successive signals from said sensing means is a stepping switch having a number of output contacts, said means for detonating includes individual detonating devices each respectively connected to a respective one of said number of pyrotechnic devices, and a respective one of said output contacts is connected to a respective one of said detonating devices.
Claim 4
Dependent Claim
29 words
Apparatus as in claim 2 further comprising a power source; and a key operated safety switch for interconnecting said stepping switch and said sensing means to said power source.
Claim 5
Dependent Claim
36 words
Apparatus as in claim 1 wherein said sensing means is connected to said target by a sound-conducting path and generates said signal in response to the sound transmitted therethrough consequent upon a hit on said target.
