  • Patent number: 6553372
    Abstract: A natural language information retrieval (NLIR) system employing a hash table technique to reduce memory requirements and a proxy process module to improve processing speed on multi-processor platforms. The NLIR system includes a Dynamic Link Library (DLL) search engine annex that implements a number of improvements that allow the preexisting natural language processing (NLP) core code module to operate sufficiently fast in a limited-memory environment. The improvements relate to (1) reducing storage requirements, (2) increasing processing speed, (3) improved operation on multi-processor platforms, and (4) a trouble-shooting mechanism. The NLIR system includes three modes of operation. First, during index processing, the NLIR system prepares documents for NLP searching to create a group of searchable documents.

  • Patent number: 5684510
    Abstract: A method of displaying characters on a pixel oriented grayscale display device having a predetermined pixel resolution employing parametric, geometric glyph descriptors is disclosed. The process supports a client process that passes a request for a particular font and a physical character height for the displayed characters as well as the physical resolution expressed in pixels for unit length. A character space height value in pixels is determined and compared to selected values to determine whether the character space height in physical pixels falls into one of three distinct ranges. If within the smallest range, no hinting or grid fitting is performed and the physical pixel coordinates of a scaled glyph descriptor are scan converted using subpixel coordinates. The on subpixels within each pixel are counted to provide a grayscale value for illuminating that particular pixel.
