  • Two-axial alignment of magnetic platelets
    Patent number: 8137762
    Abstract: A method of planarizing a plurality of orientable non-spherical flakes supported by a longitudinal web is disclosed. A web supporting a coating of field orientable non-spherical flakes is placed between magnets so that the fields from the magnets traverse the web. First and third magnets are provided on one side of a feedpath and a second magnet is provided between the first and third magnets on the other side of the feedpath.
    Type: Grant
    Filed: August 17, 2009
    Date of Patent: March 20, 2012
    Inventors: Vladimir P. Raksha, Paul G. Coombs, Charles T. Markantes, Wilfred C. Kittler, Jr., Dave Williams, John D. Sonderman, Cornelis Jan Delst

  • Variable filter-based optical spectrometer
    Patent number: 6785002
    Abstract: An optical spectrometer uses a tapered Fabry-Perot type variable optical filter in conjunction with an optical detector array. The filter can be a long-pass, short-pass, or narrow bandpass filter. The stability of the variable optical filter allows high resolution, depending on the number and spacing of the detectors used. In a further embodiment, signal-processing techniques are used to enhance the resolution of the spectrometer beyond the measured response.

  • Variable filter-based optical spectrometer
    Publication number: 20020131047
    Abstract: An optical spectrometer uses a tapered Fabry-Perot type linear variable optical filter in conjunction with an optical detector array. The filter can be a long-pass, short-pass, or narrow bandpass filter. The stability of the variable optical filter allows high resolution, depending on the number and spacing of the detectors used. In a further embodiment, signal-processing techniques are used to enhance the resolution of the spectrometer beyond the measured response.

  • High ratio planetary drive system and method for vacuum chamber
    Patent number: 5124013
    Abstract: A high ratio planetary drive system, a vacuum processing chamber system incorporating the planetary drive system, and a method of operating the system are disclosed. The planetary drive system provides relatively slow planetary workpiece rotation for effecting processing (deposition and reaction) of thin films, in particular, optical thin films, with complete film oxidation, controlled film uniformity, reduced bearing wear and reduced heat dissipation.
