Latest Patents

Walter Feulner holds a patent for a method and apparatus for monitoring and evaluating the quality of color. This invention involves the use of color control strips that are monitored by a light beam. The light beam reflects off successive increments of the patches of the strip and passes through filters in a filter wheel. The resulting color density signals are stored in memories, with each memory dedicated to a specific color. When the memories reach capacity, the oldest stored signal is erased to make room for new data. A microcomputer evaluates the stored profiles, discarding certain signals and processing the remaining ones to determine the boundaries between neighboring patches. This evaluation process includes comparing the oldest and most recent signals to ascertain color density at the center of each patch.
