  • Article identification reader, marker element for article identification and method of article identification
    Patent number: 10325439
    Abstract: A reader for article identification comprises one or more solenoids configured to generate a magnetic field for locally exciting portions of a marker element carrying at least one data feature as the marker element moves through the magnetic field and for causing the marker element to generate a varying magnetic field; and one or more giant magnetoimpedance (GMI) sensors upstream of the one or more solenoids configured to detect the varying magnetic field and produce output based on the varying magnetic field.
    Type: Grant
    Filed: July 5, 2016
    Date of Patent: June 18, 2019
    Assignee: Custom Security Industries, Inc.
    Inventors: Morton Roseman, Piotr Rudkowski, Grazyna Rudkowska, Arthur Yelon, David Menard, Stephan Brauer

  • Ceramic fibers, and methods, machines and compositions of matter for making same
    Patent number: 5605870
    Abstract: A free formed ceramic filament has a small, uniform diameter throughout and is substantially 100% dense, made from a material which exhibits a viscosity of less than 10 poise and has a physical structure that is partially amorphous with the balance, made up of complex crystals which are less than about 5 microns or substantially made up of complex crystals which are less than substantially 5 microns and has an outer surface which is substantially smooth throughout, except for a substantially linear matt surfaced line, which extends longitudinally along the outer surface of the filament.
