ALEXANDRIA, Va., Jan. 11 -- Xerox, Norwalk, Conn., has been assigned a patent (8,351,080) developed by Palghat Ramesh, Pittsford, N.Y., and Peter Paul, Webster, N.Y., for "least squares based coherent multipage analysis of printer banding for diagnostics and compensation."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method, system, and computer program product for estimating a banding profile in an image printing system is disclosed. The method includes obtaining image data across multiple measurement intervals by one or more sensors; combining the image data with timing information into a coherent signal by a processor; estimating periodic and aperiodic components of the coherent signal using least squares estimation by the processor, wherein the periodic component represents a banding profile; and wherein at least the periodic component is used to generate an output."
The patent application was filed on Sept. 8, 2009 (12/555,308). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,351,080&OS=8,351,080&RS=8,351,080
