Abstract: A backing structure of an antenna reflector for satellite communication to increase the stiffness and the frequency of the antenna reflector, having a deployable panel attached to a spacecraft at a hinge/gimbal interface and a plurality of hinge-release points. The backing structure has a plurality of first ribs and second ribs protruding from the deployable panel and extending substantially across the center of mass of the deployable panel. The first ribs connect the hinge-release mechanism points across a center of mass of the deployable panel, and the second ribs connect the hinge/gimbal interface point to the hinge-release mechanism points, which allows improved hinge-release mechanism attachment with a nut.

Abstract: A sighting device for use with an archery bow for hunting or target purposes, utilizing light emitting diodes which are battery operated and the intensity of which may be varied manually. The light emitting diodes are mounted at the ends of sighting pins which may be adjusted both vertically and horizontally, to compensate for distance and windage. The light emitting diodes are shaped so as to protrude beyond the end of the sighting pins and thus under bright ambient light conditions function to gather and disperse said ambient light even though not electrically energized.
