Abstract: In a preferred embodiment, a portable display is formed of a plurality of assembleable panels, each of panels having a plurality of edge portions secured together with corner connectors to form a rectangular framework. Panelar sheet material extends over two side of the framework and polyurethane foam in injected into the interior space. Panel connector portions, either of the sliding type, or the peg or plug-in type secure the panels together to form the display. In a preferred embodiment, each panel has four corners each with corner components that engage with the edge portions, preferably by insertion into receiving openings in said edge portions. Said corner components having a receptacle exposed at each corner to permit either connection with plug-in components, for example, panel connectors for vertical stacking of panels or accessory brackets.

Abstract: A portable display formed of a plurality of assembleable panels having wire management permitting concealment of wire for powering accessories within the junctures between panels. In a preferred embodiment, the panel edges have edge portions formed with outwardly facing channels defining or including wire conduits. Panel connector portions, either of the sliding type, or the peg or plug-in type secure the panels together to form the display. In a preferred embodiment, each panel has four corners each with corner components that engage with the edge portions, preferably by insertion into receiving openings in said edge portions. Said corner components having a receptacle exposed at each corner to permit either connection with plug-in components, for example, panel connectors for vertical stacking of panels or with accessory brackets.

Abstract: An object-based computerized graphics system for reproducing an image on a display device having a plurality of scan lines upon each of which a plurality of pixels are reproducible. The system includes information-providing means for providing graphic object information for at least one graphic object intended for reproduction, the graphic object comprising an outline representation of the graphic object. The outline representation is formed from at least two curve fragments, each curve fragment being defined by a single non-parametric quadratic polynomial. Also included in the system is rendering means for rendering the at least one graphic object. The rendering means is configured to determine, for each curve fragment, a first intersection between each curve fragment and a scan line of the display device. The rendering means is also used to determines using two computer-implemented mathematical operations, each subsequent intersection between each curve fragment and other ones of the scan lines.
