  • Patent number: 10303941
    Abstract: Provided are methods and systems for identifying location of light sources from airborne aircraft. Light sources are ground based and may be low power lasers and other like devices. An aircraft equipped with a detecting module, such as a camera of a ground maneuver camera system, may defect light source output and associate this output with the relative position of the aircraft to the light source. This information may be analyzed together with aircraft location information (at the time of light source detection) to generate a light source location estimate. In some embodiments, other information, such as transmission from other aircraft and/or ground based nodes can be used. The estimate may be transmitted to a ground based node, such as a law enforcement unit. The data from multiple aircraft and/or ground based nodes may be aggregated to more precisely identify the light source location.

    Abstract: An improved theater geometry which is capable of providing improved image resolution and improved image contrast over prior systems is achieved with a unique projection geometry and image re-mapping technique. The projected image is provided with a continuously variable image resolution and brightness over the surface of a preferably dome-shaped screen which is to receive the image, concentrating the resolution and the brightness of the image within the central field-of-view of viewers that are unidirectionally seated in the theater, and sacrificing resolution and brightness toward the outside edges of the viewers' field-of-view. The result is a more efficient use of available projector resolution and brightness, an increase in the number of quality seats available in the theater, and an enhanced image contrast due to reductions in the light which is scattering from image elements to the rear of the screen.

A two position beam splitter is arranged so that in a projector operating mode, the beam splitter is positioned out of the target projector image light path, and in a projector maintenance mode, the beam splitter is positioned in the image light path. A photo-sensitive array is positioned relative to the beam splitter such that light from the display screen is redirected from the light path onto the array. During the maintenance mode, reference light points are generated on the display screen, and the target projector is precisely aligned by use of processing the images captured by the array to calculate an error signal representing the distance between the light point image and the center of the array.

  • Patent number: 5224860
    Abstract: A "hardware-in-the-loop" simulator (10) for training people in the use of a missile system to teach target acquisition, missile launch, and missile guidance under simulated battlefield conditions. A battlefield environment (E) including at least one target (T) movable therewithin is created by a simulation module (12). Missile system hardware (H) including the missile acquisition, tracking, and guidance portions is provided. An interface module (20) converts signals produced by the simulating module to an infrared image acceptable by the hardware. The resultant image represents a field-of-view (FOV), including the target, within the battlefield environment. An image module (32) produces a dynamic image representative of the missile's position in the field-of-view. This image is observable by the hardware which utilizes it to determine the position of the missile relative to the target. The hardware also determines if a missile guidance signal is to be sent to the missile to guide it to the target.

  • Patent number: 4941263
    Abstract: An optical system for aiding the driver of a vehicle in judging the proximity of the forward end of the vehicle to an object directly in front of the vehicle, particularly when parking close to a wall or barricade or when pulling up close to another vehicle stopped at an intersection. An illuminated target and a mirror mounted beneath opposite sides of the dashboard are used to reflect an image of the target off the interior surface of the windshield at a location so that the reflected image is in the normal field of view of the driver. A virtual image of the target is perceived by the driver to emanate from a position above the forward end of the vehicle. The driver may gradually advance the vehicle until the virtual image appears to the driver to be juxtaposed with the object at which time there will be a predetermined minimum safe distance between the forward end of the vehicle and the target.
