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. |

DETAILED DESCRIPTION A simulated weapon according to one aspect of the invention includes a pressure sensor carried by a frame and coupled to a light emitter that emits a light beam in response to detected pressure changes.
The simulated weapon may include a frame shaped according to a conventional firearm, such as a pistol or a rifle.
The pressure sensor is mounted within the barrel of the simulated weapon and includes a spring-driven plunger mechanism.
A gas cartridge shaped according to conventional ammunition is placed within the gun barrel and activated by a firing pin controlled by the simulated weapon's trigger.
When the gas cartridge is activated, the cartridge releases gas to pressurize the barrel and activate the pressure sensor.
In response to activation of the pressure sensor, the optical emitter emits a beam of light outwardly from the simulated weapon.
Like a conventional weapon, the simulated weapon preferably emits a loud "report" as the gas is expelled from the gas cartridge.
Additionally, the expulsion of gas from the gas cartridge preferably causes a recoil of the simulated weapon, further simulating actual weapon fire.
Also, the gas cartridges may be sized and shaped like conventional ammunition and are ejected from the simulated weapon with a conventional ejector mechanism producing debris similar to that of conventional weapons.
Thus, the simulated weapon can produce sound, recoil, and debris in a conventionally sized, untethered weapon, without the danger, complexity and cost of emitting and tracking lethal or nonlethal projectiles.
In a weapons training environment according to the invention, a participant aims the simulated weapon at a projected image and activates the simulated weapon, causing the simulated weapon to emit a beam of light.
Optical detectors detect light spots produced by the light beams.
A microprocessor-based central controller then determines the accuracy and timeliness of the participant's fire by comparing the location of the light spot to a desired impact location
