Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

F41F 2700

US Classification:

434 18

Abstract:

A recoil simulator is disclosed in which one end of a flexible cable is ached to a weapon and the other end to a system comprising a rotating shaft and a clutch. As the trigger of the weapon is pulled a signal is produced which activates the clutch. The clutch creates a sudden pull on the end of the flexible cable simulating recoil.

International Classification:

F41G 326

US Classification:

434 22

Abstract:

The apparatus is an interactive, scenario based simulator for training a weapons team in close encounter combat. Employed is a large screen projection system, a plurality of trainee positions, and means to remove aggressor images when neutralized by the team, to provide an apparent threat to the trainees from the simulated aggressors, and to track each trainees performance throughout the training scenario.

International Classification:

F41G 326

US Classification:

434 22

Abstract:

A linear motion and pop-up target training system is disclosed for training a marksman to fire a simulated weapon. Located upon the terrain surface of a modelboard are six pop-up targets and three bi-directional linear motion targets, each of which emits, when activated by a first microprocessor computer, a pulsed beam of infrared light. Mounted upon the weapon is a sensor which will sense the pulsed beam of infrared light emitted by the activated target. The sensor then supplied to a rifle electronics circuit an analog signal proportional to the amount of light received by the sensor, and the rifle electronics circuit converts the analog signal to a digital logic signal to be supplied to a second microprocessor computer. The second microprocessor computer then processes the digital logic signal in accordance with a predetermined computer program so as to determine whether the marksman has scored a hit, a miss, or a near miss upon the activated target.

International Classification:

F41G 326

US Classification:

434 22

Abstract:

The invention is a marksmanship trainer that can accommodate a plurality of trainees. The trainer includes a long range light pen to measure sighting accuracy and tracking steadiness. It is set with the sight of a simulated or operational weapon, and achieves resolution to the pixel level by using telescope optics and special purpose circuitry in addition to its computer board. Each trainee is provided with a raster scan display and a computer that provide a target image and corrective feedback to the trainee. Bridge configured dual strain gauges are used to sense breathing, and a force sensing resistor is used to monitor trigger squeeze. Recoil is simulated mechanically, and a simulated report of the weapon is provided through a headset. The feedback of corrective action is provided aurally/graphically from a stored expert library.

Appl. No.:

Albert H. Marshall - Orlando FL
Randy R. Fields - Winter Park FL

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

F41G 326

US Classification:

434 22

Abstract:

A marksmanship training system has been developed which depends upon the mal levels of infrared radiation emitted from warm-blooded animals, such as humans. An infrared detector is mounted upon a simulated rifle or unloaded real rifle, or other weapon. This detector is mounted with IR lenses in such a way that a positive indication is given when the rifle is pointed at a suitable infrared emitting animal target. A second detector indicates when the trigger of the weapon is pulled. If a trigger pull is detected at a time when an animal infrared signal is present, the system generates an electronic pulse indicating that a target hit has occurred. This pulse may be used to drive a visible or audible signaling device to inform the user of success.

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

F41J 508

US Classification:

434 20

Abstract:

A simulated thermal sight utilizes a computer to store digitized video data erived from photographs of actual thermal images. The computer inserts video images formed from the data into optical telescopes, via a miniature TV and mirror system, to simulate a thermal image for a trainee. An IR detector and emitter, whose location corresponds to the apparent location of the thermal image, are used to measure aim error and provide an input to the computer.
