Electronic firing rate controller for remote operation of an automatic firing weapon
An electronic apparatus for controlling a firing rate of an automatic firing weapon having an actuator operating a trigger mechanism of the weapon, the weapon exhibiting a natural free-running firing rate when triggered. An output driver element provides a drive signal for the actuator, a first single pulse generator element having a single pulse output coupled to an input of the driver element and generating a single pulse of a duration shorter than a time period of the natural free-running firing rate in response to a single pulse generator element input, and a pulse train generator element having a single pulse output coupled to an input of the first single pulse generator element and providing the first single pulse generator element a train of pulses spaced in time a spacing period exceeding the time period of the natural free-running firing rate in response to a pulse train generator element input.
1. An electronic apparatus for controlling a firing rate of an automatic firing weapon having an actuator adapted to operate a trigger mechanism of said weapon, said weapon exhibiting a natural free-running firing rate when held triggered, said apparatus comprising
an output driver means (SDRV) adapted to provide a drive signal (Q) for said actuator,
a first single pulse generator means (MMV 1 ) having a single pulse output (Q 1 ) coupled to an input (A) of the output driver means and adapted to generate a single pulse of a duration shorter than a time period of said natural free-running firing rate in response to a single pulse generator means input (T S ), and
a pulse train generator means (AMV 1 ) having a single pulse output (Q 2 ) coupled to an input (A 1 ) of said first single pulse generator means and adapted to provide to the first single pulse generator means a train of pulses spaced in time a spacing period exceeding said time period of said natural free-running firing rate in response to a pulse train generator means input (1/T R ).
2. The electronic apparatus of claim 1 , further comprising a trigger switch (T) adapted to provide to a mode selector (M) a trigger signal in response to an operation of said trigger switch, said mode selector adapted to couple said trigger signal to first (FSU), second (SSC) and third (MSC) mode selector outputs, said first mode selector output coupled to said input (A) of the output driver means, said second mode selector output coupled to said input (A 1 ) of the first single pulse generator means, and said third mode selector output coupled to an input (A 2 ) of the pulse train generator means to provide said pulse train generator means input.
3. The electronic apparatus of claim 2 , further comprising a second single pulse generator means (MMV 2 ) having a single pulse output (Q 3 ) coupled to the input (A 2 ) of the pulse train generator means and adapted to generate a single pulse of a duration longer than said spacing period of coinciding pulses of said train of pulses, and said mode selector further adapted to couple said trigger signal input to a fourth (BSC) mode selector output coupled to a control input (A 3 ) of said second single pulse generator means.
