Abstract
Abstract A laser operated transmitter is attachable to the barrel of gun and comprises a battery operated power supply; a first, hit-code pulse generating circuit capable of driving a laser optical system and producing a beam simulating a projectile hitting a photodetector target system; and a second inhibit-code pulse generating circuit, synchronous with the hit-code pulse generating circuit, driving a light emitting diode and producing a hit-code inhibiting wide-angle beam aimed towards a photodetector target system worn by the shooter of the gun.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
109 words
A laser operated small arms transmitter attachable to the barrel of a gun for producing a coded laser beam simulating the trajectory of a projectile comprising: a laser optical means including hit code pulse generating means and an internal power source means and an internal power source means whereby said laser optical means produces a beam simulating a projectile directed toward a photodetector target system; a light emitting diode optical means including a second inhibit code pulse generating means whereby a hit code inhibiting wide angle beam, synchronous with said hit code pulses, is produced and directed towards the photodetector target system worn by the shooter of the gun.
Claim 2
Dependent Claim
109 words
A laser operated small arms transmitter attachable to the barrel of a gun for producing a coded laser beam simulating the trajectory of a projectile comprising: a laser optical means including hit code pulse generating means and an internal power source means and an internal power source means whereby said laser optical means produces a beam simulating a projectile directed toward a photodetector target system; a light emitting diode optical means including a second inhibit code pulse generating means whereby a hit code inhibiting wide angle beam, synchronous with said hit code pulses, is produced and directed towards the photodetector target system worn by the shooter of the gun.
Claim 3
Dependent Claim
82 words
A laser operated small arms transmitter according to claim 1 whereby said hit pulse generating means includes means to produce a code comprising a plurality of bit slots wherein at least one bit slot is not filled and said second inhibit code pulse generating means includes means to produce a code comprising a plurality of bit slots wherein all the bit slots are filled with bits, said bits having an energy level at least as high as the hit code pulse bits.
