Abstract: This invention provides a mounting structure 10 for releasably securing an auditorium seating unit to the floor. The mounting structure includes a bracket support 12 which is a rectangular casing 32 equipped with openings 40 & 42 interconnected with a pathway slot 46. The mounting structure includes a plate member 16 that is permanently part of the leg or stanchion of the seating unit. The plate member has a stud fastener 52 and a nut/bolt arrangement 62 that depends from the plate member and are received in the openings 40 & 42. The stud 52 and the nut/bolt arrangement 62 are received in the pathway slot 46 and the fasteners 52 & 62 are guided into the openings 40 & 42. The stud 52 and nut/bolt 62 secure the seating unit to the bracket support 12. Cover plates 114 serve to cover the exposed bracket support 12 absent the seating unit 28. The plate member is equipped with a guide element 102 to facilitate locating the openings when restoring the seating unit to this auditorium.
Abstract: An integrated dual day night backlight includes a flat channel light source with an auxiliary night light source suitably filtered to remove infrared components from the illumination. In alternative embodiments, the night light can be a separate bulb or it can be separate light channels within the flat channel source. The night illumination is directed through the edge of the light transmissive face plate that covers the main or day channel. The light directing means can be an inner reflecting surface of the face plate or can be a separate reflective element that redirects the illumination from the night channel through the edge of the transmissive face plate.

Abstract: A digital address filter is provided which converts straight-line and arc analog stroke data into digitized images which comply with Bresenham raster display criteria and can be displayed on a raster scanned monitor or LCD. Data collected over a preselected (M pixel.times.M pixel) spatial window are repetitively matched against a set of pixel template patterns permitted by the Bresenham criteria. After each full-frame iteration, the display pixel(s) corresponding to the best-fit templates are lighted.
