Patents by Inventor John Jefferies

John Jefferies has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of manufacturing circuits
    Patent number: 7642126
    Abstract: The method uses a laser beam directed through the substrate to the conductive area of the substrate in order to bond the two together.
    Type: Grant
    Filed: September 30, 2002
    Date of Patent: January 5, 2010
    Assignee: Poly-Flex Circuits Limited
    Inventors: Neil Kirby, John Jefferies
  • System and method for flattening spans
    Patent number: 6996284
    Abstract: A system and method for computing a run-length encoded raster in which spans are successively added to a raster or overlapping spans are flattened. Spans are temporarily expanded into a pixel array representing part of the raster, where entries in the pixel array are references to color values and other property data. Successive spans modify the pixel array. References in the array are then compared to run-length encode the partial raster. Remaining parts of the raster are processed similarly. In one embodiment, the array contains pointers referencing color and property information. In another embodiment, the array contains small indexes referencing a color palette.
