Patents by Inventor Frederick B. Sherburne

Frederick B. Sherburne has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4163328
    Abstract: An electro-optical apparatus for marksmanship training wherein a simulated cene is presented on a screen by a motion picture projector. The marksman or trainee operates a weapon, which includes a module to develop a laser beam, to simulate firing at a target on the scene. The apparatus provides an improved optical system including a dichroic mirror which permits the light which projects the target scene to pass through the mirror for providing an improved scene illumination while reflecting substantially all the laser beam energy to activate a target hit detector.
    Type: Grant

  • Patent number: 4161070
    Abstract: A system for facilitating the training of a trainee to operate a target refinder. The system includes a slide (or film) projector for projecting a battlefield scene including one or more targets onto a viewing screen. The slide includes data annotated thereon corresponding to the range of the target; the target range is communicated to an operating console. A rangefinder simulator includes a means for generating a laser beam. In operation, the trainee sights the target, sets the range gate and fires the laser beam. When the laser beam hits the target, the console displays the proper range data which is then compared to the range set on the simulator by the trainee.

  • Patent number: 4137651
    Abstract: An electro-optical system for weapons training, consisting of a low-power e-safe laser beam simulating the weapon's fire, a realistic moving target scene projected by a moving picture projector or slide projector onto a screen, a laser beam hit detector based upon a second projector, and a display board for displaying the hits and attempts of each trainee. Multi-station operation is accomplished by a digitally multiplexed time sharing system which allows each laser beam to fire only during a discrete time interval regulated by encoder pulses transmitted by radio. The laser beam detector is synchronized with the film of the target projector and acts as an annotated mask, this mask being opaque except for transparent areas corresponding to the target areas projected by the projector. A properly aimed laser beam will pass through the transparent area of the mask and be counted as a hit by the hit detector.
