Abstract:
An orthogonal projection concealment apparatus comprising,a mobile platform equipped withan internal power source, communicating power by and connected by appropriate wiring means toa power controller, communicating power by and connected by appropriate wiring means toa pixel array on said mobile platform surface consisting of a multiplicity of pixels, and said mobile platform further equipped withat least one means of sensing and manually inputing digital estimates of observer position and distance, andat least one means of sensing digital estimates of background distance automatically, andat least one means of continuously capturing digital background images,all means communicating electronic data by and connected by appropriate wiring means to said internal power source and additionally to,a microchip driven computing device, communicating data input by and connected by appropriate wiring means to said power controller, and said computing device comprising,a pixel location database, andprogrammed means of observer visible pixel selection, andgray-scale determination means of occulted background position, andpositional algorithmic computational means, andprogrammed means whereby said power controller activates an individual pixel to project an orthogonal image of a portion of said occulted background perpendicular to the observer in his line of sight, whereby the summing of the orthogonal images of all portions of said occulted background produces a concealed orthogonal projection of the total occulted background.
