  • Patent number: 6778183
    Abstract: A method and apparatus that allows a display device to adaptively and automatically control display contrast and color is disclosed. The method and system in accordance with the present invention can be described by the following sequential process: 1. Separating an input image data value into its luma and chroma components. 2. Collecting the luma distribution data over the entire image or a specified window. 3. Analyzing the luma distribution. 4. Generating an appropriate contrast control response that modifies the input luma component to generate an output luma component, on a pixel by pixel basis. 5. Analyzing the input luma component and the output luma component, and an input chroma component, to generate an appropriate modification for the chroma component, on a pixel by pixel basis.

  • Publication number: 20040036696
    Abstract: An apparatus and method for allowing color adjustments in display devices is disclosed The apparatus comprises a multi-resolution structure for providing color adjustments; and an interpolator for interpolating at least one offset of the multi-resolution structure. An apparatus and method in accordance with the present invention uses a combination of color look-up tables with different levels of resolution, followed by interpolation to provide a display process which has high resolution but utilizes minimal memory. In so doing, memory is used for high-resolution areas only where needed. The multi-resolution structure is a very good approximation to the theoretical mapping table in the areas where it is needed. At the same time, since the high resolution areas are localized, a significant reduction in memory storage is possible.

  • Publication number: 20040000482
    Abstract: Methods for removing a non-enveloped virus from a sample containing a target compound and non-enveloped virus contamination place the sample containing the target compound in a solvent chamber of an electrophoresis apparatus having a cathode and an anode, and a first solvent chamber being separated from a second solvent chamber by a separation barrier that has a defined pore size. The solvent chambers and the separation barrier are located between the cathode and anode.

  • Patent number: 5731278
    Abstract: Low cost, highly aqueous, thickened heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of surfactant materials, a formate-based viscosity-enhancing agent, a selected type of thickening perfume and relatively large amounts of water. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.

  • Patent number: 5587356
    Abstract: Low cost, effective aqueous heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of an anionic/nonionic-based suffactant system along with a protease-containing enzyme component, a low-cost viscosity-enhancing agent and relativly large amounts of water. The anionic component of the surfactant system comprises a combination of alkyl sulfate and alkyl ether sulfate. The nonionic component of the suffactant system comprises fatty alcohol ethoxylates. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.
