  • Method and apparatus for producing duplication- and imitation-resistant identifying marks on objects, and duplication- and duplication- and imitation-resistant objects
    Patent number: 7188258
    Abstract: A method (and system) for guaranteeing authenticity of an object, includes providing a sample of material obtainable only by at least one of chemical and physical processes such that the sample is random and not reproducible, associating a number reproducibly to the sample by using a specific reader, and forming at least one coded version of the number, the at least one coded version being obtained by a key signature, and the version being recorded into an area of the object.
    Type: Grant
    Filed: September 17, 1999
    Date of Patent: March 6, 2007
    Assignee: International Business Machines Corporation
    Inventors: Gaurav Aggarwal, Nabil Mahmoud Amer, Vernon Ralph Austel, Pradeep Kumar Dubey, Ashutosh Kulshreshtha, Marco Martens, Bruce Albert Scott, Sean William Smith, Charles Philippe Tresser, Robert Jacob von Gutfeld, Steve Harris Weingart, Chai Wah Wu
  • Dual gate field effect transistor utilizing Mott transition materials
    Patent number: 6365913
    Abstract: A Field effect transistor semiconductor switch in which the channel of same is made from materials having an electrical conductivity which can undergo an insulator-metal transistor (i.e., Mott transition) upon application of an electric field. The channel contains the Mott material in which the charge carriers, either holes or electrons, are strongly correlated. The Mott transition determines the metal-insulator switching and is demonstrated to be controlled by an external gate electrode.

    Inventors: James Anthony Misewich, Alejandro Gabriel Schrott, Bruce Albert Scott
  • Process of optically printing highly conductive character utilizing a medium containing a halogenated hydrocarbon photoactivator and a tetrathiafulvalene or a related compound thereof
    Patent number: 4082552
    Abstract: A method of optically printing conductive characters using charge transfer compounds is provided. The method is characterized by depositing an organic .pi. electron donor compound dissolved in a halogenated hydrocarbon (halocarbon) on a suitable substrate and selectively exposing the so coated substrate to actinic radiation to obtain a permanent, highly conductive, image.
    Type: Grant
    Filed: February 17, 1977
    Date of Patent: April 4, 1978
    Assignee: International Business Machines Corporation
    Inventors: Edward Martin Engler, Frank Benjamin Kaufman, Bruce Albert Scott
  • Method of depositing metal conducting patterns on large area surfaces
    Patent number: 4052272
    Abstract: A method of depositing conducting patterns on a large area surface is disclosed. The method is characterized by photochemically depositing an electrically conducting organic .pi.-electron donor compound on an insulating surface and selectively depositing a metal onto the established conductive pattern while simultaneously removing the organic film.
