  • Patent number: 7903285
    Abstract: What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.

  • Patent number: 7902462
    Abstract: This invention is a novel saddle that comes in two embodiments, a vertical saddle and a horizontal saddle. Each saddle is configured to hold a power harness (or assembly of wires) and a signal harness, also an assembly of clustered wires. The saddle eliminates or greatly reduces the occurrence of electrical cross talk between these two harnesses by electrically insulating them from each other while securing each in place by a spring holder. These saddles greatly reduce electrical interference while significantly reducing installation time of the assembly. While this invention is described as used in a xerographic system, the saddle can be used in any system containing large bundles of electrical wires or cables.
