Kenneth Russell Ossman 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).

  • Systems and methods for increasing or optimizing the optical contrast response of multiple colors
    Patent number: 8075084
    Abstract: Methods and systems are provided to increase or optimize the illumination used with a sensor to measure printed ink colors on a substrate at high speed (up to 3 m/s) and high resolution. By modifying the number of light sources, their wavelengths and/or their relative intensities, the optical contrast can be increased or optimized to yield a higher signal-to-noise ratio and improved accuracy for the measurement of multiple colors. In one implementation, multiple LEDs with selected output peak wavelength may be used to achieve higher contrast imaging for each color.
