  • Patent number: 5980254
    Abstract: A weapons training range provides a simulated weapons use scenario including return fire. A microprocessor selects branches from a multi-branch program and causes an image projector to project subscenarios on a display screen visible to a participant. In response to the subscenarios, the participant fires at projected threats. Return fire simulators positioned behind the display screen return fire toward the participant. Obstructions are placed in the weapons range to provide cover for the participant. A video camera and X-Y position sensor identify the X-Y location of the participant and try to detect exposed portions of the participant. Based upon the identified X-Y location and any detected exposed portions, the microprocessor aims the return fire simulators to provide simulated return fire. To simulate real world aiming, the microprocessor induces time-based and response-based aiming errors.

  • Patent number: 5947738
    Abstract: A simulated weapon includes a pressure switch within the simulated weapon's barrel. The pressure switch responds to pressure changes within the weapon barrel to activate a light emitter. In response, the light emitter emits a beam of light that simulates weapon fire by indicating the aim of the simulated weapon. Pressure changes within the barrel are induced by a conventional air cartridge that emits a blast of air when struck by the firing pin of the simulated weapon. The user can thus produce the simulated fire by activating the simulated weapon's trigger to trip the hammer and drive the firing pin into the air cartridge. In another embodiment, the simulated weapon activates a nonlethal pyrotechnic round. Simulated fire is produced in response to detection of the recoil, force, or pressure change produced by the pyrotechnic round. The simulated weapon may be a pistol, rifle or any other conventional hand held weapon.
