  • Patent number: 10436538
    Abstract: A slide for an automatic pistol includes a cavity, a housing in the cavity, a laser module at least partially received in the housing, a power source, circuitry, and a striker. The slide has a first mode in which it emits laser light and a second mode in which it does not emit laser light. The striker has a first position in which it does not cause the laser module to emit laser light. When the pistol's trigger is pulled, the pistol's firing pin contacts the striker and moves the striker backwards from the first position to a biased position. When the firing pin moves out of contact with the striker, the striker moves forward to a second position and causes the circuitry to transmit power from the power source to the laser module, which causes the laser module to emit laser light.

    Abstract: A firearm training apparatus and method provides simulated weapon realism that places higher priority to shot placement by using a culminated laser beam with specific target areas to achieve marksmanship accuracy. Trainee shooters can visually observe hits by an LED in the target area and hear an alarm sound when another trainee is hit. Stress and reaction to stress is achieved through the use of a TENS (transcutaneous electrical nerve stimulation) units in vests worn by the trainees. Greater realism is achieved by eliminating special safety equipment required with projectile systems, and focus on weapon accuracy and firing characteristics.

  • Patent number: 4234911
    Abstract: An optical apparatus adapted for insertion into the open end of a hand-gun barrel. A piezoelectric crystal produces an output signal in response to the hammer impact to cause an LED to be intermittently operated by an oscillator powered by batteries and produce pulses of light which are directed by a lens onto a target. The oscillator is also coupled to a counter which is reset by the crystal output and which disables a gate between oscillator and LED upon a first count and enables a gate connecting the counter reset to the crystal upon a second count.

  • Patent number: 4172274
    Abstract: This invention relates to an improved construction for a gun barrel bore illuminator, which provides non-glare illumination for the interior of a gun barrel bore. The non-glare illumination facilitates visual inspection of the bore, allowing the inspector to look directly into the muzzle of the gun barrel. The illuminator includes an electric light bulb socket, adapted to be positioned in the breech end of the gun barrel. A light bulb is mounted in the electric light bulb socket to provide a light source. An electric power source is connected to the light bulb to cause the light bulb to emit light. A switch is interposed between the power source and the light bulb to control the electric power to the light bulb. A translucent light diffuser encloses the light bulb to diffuse the light from said light bulb along the bore to provide non-glare illumination of the bore.

  • Patent number: 4136956
    Abstract: An integrated attaching and aligning apparatus for mounting a laser shot simulator or the like in gun barrels of different calibers with a barrel member of two coaxial sections which slides into the gun barrel. A first resilient ring is removably mounted about the first section at one end for engaging and centering the barrel member in the gun barrel. A second resilient ring is removably mounted on an inside barrel between the two sections at the other end of the barrel member so that axial force applied to the second ring by the second section deforms the second ring against the gun barrel to center the barrel member in the other end. A laser source receiver and lens are adjustably mounted within the barrel member.
