Abstract
Abstract A weapon direct fire kill simulator system in which a laser transmitter means of dual mode, narrow and broad beam projection, capability, a hit receiver-actuator means and hit indication means all fixed to a weapon to be simulated and having a trigger switch are combined with a man target means having retroreflective apparel or patches to reflect the narrow fire beam back to the hit receiver-actuator and combined also with a 360* kill detector-actuator means to receive the kill beam to actuate a kill indicator alarm also made a part of the man target wearing apparel. The invention also contemplates a timing means and adjustable range gate means to disable the system when the target is beyond the simulated weapon''s range, comparator means to eliminate noise signals below the value of the hit indicator signals, and disabling means to inactivate a man target once hit. In composite, the system provides immediate hit indication to the trainee and kill indication to the man target while also correcting for weapon characteristics.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A weapon fire kill simulator system comprising: a. laser transmitter means for producing a narrow fire beam and a wide angle kill beam, b. laser power source means and hit detector-actuator means, c. a weapon having a trigger switch and means for mounting all said above mentioned means integral with said weapon and in position to direct said laser means and said hit detectoractuator means in the direction in which said weapon is aimed, d. a man target carrying equipment including apparel or patches of retroreflective material, a 360* kill beam detector-actuator means and an alarm system actuated from said kill detectoractuator means upon energization of the latter, e. said laser means being connected for producing said fire beam when said trigger switch is closed to direct said fire beam to said target and a retroreflected fire beam from said apparel to said hit detector-actuator means, f. said hit detector-actuator means being connected to actuate said laser means to produce said wide angle kill beam to actuate said kill detector-actuator and hence said alarm system.
Claim 2
Dependent Claim
175 words
A weapon fire kill simulator system comprising: a. laser transmitter means for producing a narrow fire beam and a wide angle kill beam, b. laser power source means and hit detector-actuator means, c. a weapon having a trigger switch and means for mounting all said above mentioned means integral with said weapon and in position to direct said laser means and said hit detectoractuator means in the direction in which said weapon is aimed, d. a man target carrying equipment including apparel or patches of retroreflective material, a 360* kill beam detector-actuator means and an alarm system actuated from said kill detectoractuator means upon energization of the latter, e. said laser means being connected for producing said fire beam when said trigger switch is closed to direct said fire beam to said target and a retroreflected fire beam from said apparel to said hit detector-actuator means, f. said hit detector-actuator means being connected to actuate said laser means to produce said wide angle kill beam to actuate said kill detector-actuator and hence said alarm system.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1, including a. hit indicator means fixed to said weapon and connected to respond to actuation of said hit receiver-actuator to indicate a hit to a trainee firing said weapon.
Claim 4
Dependent Claim
30 words
Apparatus according to claim 2, in which a. said hit indicator means includes a light emitting diode counter and a light emitting diode visible lamp, both fixed to said weapon.
Claim 5
Dependent Claim
95 words
Apparatus according to claim 1, including a. AND gate means, b. range gate means comprising a timing pulse source connected to provide an initiating actuating pulse to said laser transmitter means responsive to actuation of said trigger pulse and an additional pulse of selected time length commensurate with the range of said weapon and provided as an enabling input to said AND gate to exclude from said hit indicator means any hit signal whose propagation time delay is greater than the time of laser pulse return from maximum target range of the weapon being simulated.
Claim 6
Dependent Claim
47 words
Apparatus according to claim 1, a. said hit receiver-actuator including a voltage comparator with adjustable reference voltage input to selectively adjust the sensitivity of said hit receiver-actuator to amplify only target hit signals and exclude noise level signals up to the strength of a target hit signal.
Claim 7
Dependent Claim
28 words
Apparatus according to claim 5, a. said hit receiver-actuator including an avalanche Type detector and amplifying means connected to provide a hit signal input to said voltage comparator.
Claim 8
Dependent Claim
95 words
Apparatus according to claim 6, including a. AND gate means, b. range gate means comprising a timing pulse source connected to provide an initiating actuating pulse to said laser transmitter means responsive to actuation of said trigger pulse and an additional pulse of selected time length commensurate with the range of said weapon and provided as an enabling input to said AND gate to exclude from said hit indicator means any hit signal whose propagation time delay is greater than the time of laser pulse return from maximum target range of the weapon being simulated.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 1, a. said laser transmitter means being two laser transmitters respectively for said hit and kill beams.
Claim 10
Dependent Claim
25 words
Apparatus according to claim 1, a. said laser transmitter means being a single laser of dual mode capability for producing said hit and kill beams.
