Patent number: 10184893Abstract: Examples relate to providing hyperspectral scanning of a surface. In some examples, motion capture data of unobstructed portions of the surface are captured, and spectral data of the surface are captured through a slit assembly and diffraction grating. The motion capture data are processed to determine a movement of a scanning device. At this stage, the spectral data are translated and rotated based on the movement of the scanning device to generate images that each correspond to a different color channel.Type: GrantFiled: February 27, 2015Date of Patent: January 22, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Charles M Santori, James William Stasiak, Garry Hinch

Patent number: 9313360Abstract: Certain methods and systems are described for encoding data in an image. According to an example, a set of metamers under a first set of conditions may be determined that vary under a second set of conditions. These may be used to generate a set of color mappings for a sampled color value, each color mapping being used for a different data value in the data. As such the data values may be detectable when the image is observed under the second set of conditions but not detectable when the image is observed under the first set of conditions.Type: GrantFiled: July 30, 2014Date of Patent: April 12, 2016Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Morovic, Jan Morovic, Peter J.

Patent number: 9256815Abstract: Certain methods and systems are described that allow the spectral control of a print output. A plurality of colorants are used where one or more colorants contain nanoparticles. Each colorants has a specified spectral range corresponding to the constituent nanoparticles. To print with these colorants a spectral separation may be used that maps an input color with associated spectral information or direct spectral information to print control data, the print control data having defined values for depositions with each combination of the colorants. The spectral separation may be constructed by characterizing a set of spectral Neugebauer primaries for the plurality of colorants.Type: GrantFiled: July 30, 2014Date of Patent: February 9, 2016Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Morovic, Jan Morovic, Peter J.
