Abstract: A firearm simulation system for enhanced firearms training comprises at least one weapon with a mechanically activated laser. The system includes a normally closed laser activation circuit used in conjunction with a recoil kit. The normally closed laser activation circuit comprises a conductive seal, a ball bearing, and a recoil spring. The recoil spring presses or urges the ball bearing into contact with the conductive seal. The function of the laser activation circuit is mechanically triggered and the laser activation circuit is electrically connected to a light source (e.g., a laser light) and configured to activate the light source, simulating a projectile being fired from a weapon. When the trigger of the simulated weapon is pulled, a striker pin dislodges the ball bearing, moving it out of its original position is contact with the conductive seal. The displacement of the ball bearing by the striker pin, away from the conductive seal, creates an open circuit.

Abstract: A firearm training simulation system for simulating the impact of one or more projectiles impacting a user includes an electrical impulse element configured for physical contact with the user. A controller is in communication with the electrical impulse element. The controller enables receipt of a signal for activating the electrical impulse element to deliver one or more electrical pulses to the user. Each electrical pulse simulates an impact of a projectile on the user.

Abstract: A threat fire simulation system (40) for simulating a projectile impacting a user (26) includes an electrical impulse element (44) configured for physical contact with the user (26). A controller (42) is in communication with the electrical impulse element (44). The controller (42) enables receipt of a signal (54) for activating electrical impulse element (44) to deliver a non-disabling electrical pulse (46) to the user (26). The electrical pulse (46) simulates an impact of the projectile on the user (26).

Abstract: In an arcade system (20), an interface circuit (38) is configured for communication with a PC (40) and one or more peripheral devices (59). The interface circuit (38) adapts a PC-based application (64), installed on and executable from the PC (40), to an automated format in order to include arcade-style features, such as video and audio cues, fee prompts, timing cues, and so forth. The interface circuit (38) includes a processor (66) in communication with a plurality of inputs and outputs on the interface circuit (38). A memory (68) is coupled to the processor (66) and includes a user-configurable control program (74) executable on the processor (66). The user-configurable control program (74) selectively translates the data received from the peripheral devices (59) to a data format that is recognized by the PC-based application (64) and selectively enables the transfer of the data from the peripheral devices (59) to the PC (40).

Abstract: A high sensitive water entry alarm system which prevents outside noise from falsely triggering the alarm system. A transmitter generates ultrasonic timed acoustic bursts at a fixed frequency when it is submerged in water. A receiver located in the body of water senses for acoustic signals similar in characteristic to the transmitter signal. A comparing circuit coupled to the receiver compares the acoustic signals received by the receiver to a reference signal having the same fixed frequency as the transmitter signal. The comparing circuit also measures the duration of the acoustic signals received by the receiver. The comparing circuit will generate a alarm signal which will sound off an audible alarm only when the acoustic signal received by the receiver has the same fixed frequency and is transmitted in controlled burst at the same timed intervals as the transmitter signal.
