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.

Abstract: A system for projecting an image of a target is provided. In one embodiment, the system comprises a rail having a longitudinal axis; a target carrier coupled to the rail such that the target carrier can translate along the longitudinal axis of the rail; a motor and motion controller coupled to the target carrier wherein the motor is configured to cause the target carrier to translate along the longitudinal axis of the rail; a projector carrier coupled to the rail and held in fixed relational position to the target carrier; and a projector affixed to the projector carrier and oriented to point back towards the target carrier. In some embodiments, one or more cameras may also be added to the target carrier, projector carrier, or both.

Abstract: A patch antenna for operation within a high temperature environment. The patent antenna typically includes an antenna radiating element, a housing and a microwave transmission medium, such as a high temperature microwave cable. The antenna radiating element typically comprises a metallization (or solid metal) element in contact with a dielectric element. The antenna radiating element can include a dielectric window comprising a flame spray coating or a solid dielectric material placed in front of the radiating element. The antenna element is typically inserted into a housing that mechanically captures the antenna and provides a ground plane for the antenna. Orifices or passages can be added to the housing to improve high temperature performance and may direct cooling air for cooling the antenna.

Abstract: A single triac on a heat sink is replaced by a plurality of lower rated current, parallel connected triacs for carrying the same total current as the single triac. The plural devices are spaced apart as far as possible, within the confines of an insulation back cover, to reduce the thermal gradient across the heat sink and to reduce the input thermal power to the heat sink. Thermally conductive compressive sheets thermally couple the flat heat sink to a face plate on the side of the heat sink opposite to the side receiving the triacs.
