Abstract
Abstract A microphone on a firearm detects the fall of the hammer and a pulse output is processed to be passed only as a result of closure of a randomly operated gate. A pulse passing through said gate encounters a selectively variable delay then directs a voltage pulse to a trainee operating the rifle, to provide a stimulus to simulate the recoil of the weapon.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
Anti-flinch training apparatus comprising: microphone means adapted to be mounted on a firearm to detect the impact of a firearm hammer and means to generate a first pulse in response thereto; gate means connected to receive said pulse; randomly operable means for sequentially and cyclically rendering said gate means and conductive and nonconductive; and further means operable in response to a first pulse passed by said gate means for applying a voltage pulse to a trainee operating said firearm.
Claim 2
Dependent Claim
79 words
Anti-flinch training apparatus comprising: microphone means adapted to be mounted on a firearm to detect the impact of a firearm hammer and means to generate a first pulse in response thereto; gate means connected to receive said pulse; randomly operable means for sequentially and cyclically rendering said gate means and conductive and nonconductive; and further means operable in response to a first pulse passed by said gate means for applying a voltage pulse to a trainee operating said firearm.
Claim 3
Dependent Claim
24 words
Apparatus as defined in claim 1 wherein said randomly operable means comprises a blocking oscillator having means for selectively varying its frequency of operation.
Claim 4
Dependent Claim
36 words
Apparatus as defined in claim 1 wherein said further means includes selectively variable delay means for delaying the application of said voltage pulse to a trainee, after passage of said first pulse through said gate means.
Claim 5
Dependent Claim
69 words
Apparatus as defined in claim 3 wherein said delay means includes a latching gate arranged to be rendered conductive by a first pulse passing said gate means, an astable multivibrator for feeding timing pulses through said latching gate and a shift register, arranged to receive timing pulses from said astable multivibrator, and means responsive to the output of said shift register for directing said voltage pulse to said trainee.
Claim 6
Dependent Claim
17 words
Apparatus as defined in claim 4 wherein the frequency of operation of astable multivibrator is selectively variable.
