  • Publication number: 20190064310
    Abstract: A system for displaying a plurality of targets and detecting the path of a projectile is provided. In a preferred embodiment, the system comprises an enclosed space with a plurality of walls wherein the walls are coated with an anti-reflective coating; a screen for displaying a plurality of targets within the enclosed space; a first area scan camera and a second area scan camera positioned on a first side of the screen, wherein the first area scan camera is positioned at a first corner of the screen and is looking at a detection zone in front of the first side of the screen and the second area scan camera is positioned in an adjacent second corner and is looking at the detection zone; a first directional light source that spans a length of the screen and is positioned outside a field of view of the first area scan camera and second area scan camera, wherein the first directional light source is directed to project light across the first side of the screen through the detection zone.

  • Patent number: 5816817
    Abstract: A method and apparatus for simultaneously training multiple trainees in the use of simulated weapons, which method defines a set of image shapes and assigns each image shape to a different simulated weapon capable of generating a light beam, at a selected wavelength, having the assigned image shape. By collecting data under control conditions and evaluating a set of parameters that uniquely identifies each image shape and by comparing the resulting "control parameters" to the same set of parameters evaluated under training conditions (thereby, producing "on-line parameters") each image shape produced during a training session is identified and associated with a simulated weapon. The method enables an expanded number of trainees to be simultaneously trained, by employing the same set of image shapes produced and detected at different wavelengths.
