Abstract: A volumetric three-dimensional light-emitting display, comprising an array of emitters arranged, as defined by the relative positions of the emitters' centerpoints, in a close-packed relationship; and an array of conductors in electrical contact with the array of emitters. The array of emitters may for example comprise conventional RGB stacks or similar full-color assemblages or four different-colored emitters.

Abstract: A system and method for processing an existing document (e.g., a patent) to discern useful information (e.g., key text items) and/or relevant locations (e.g., where such information was not originally expressly displayed) in the document, and alter the document by selectively adding discerned useful information to relevant locations. Also, a method and system for preparing a revised drawing from an existing drawing by processing the existing drawing to discern graphically distinct parts of the drawing and selectively insert desired symbolic references to discerned parts, and/or to discern existing text references and selectively replace them with symbolic references; and/or to discern extraneous and/or non-conforming drawing elements and selectively eliminate, modify, or replace them.
