Patents by Inventor Joseph J. Reczek

Joseph J. Reczek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optically configurable charge-transfer materials and methods thereof
    Patent number: 11222249
    Abstract: The present invention relates to an optical code including a film of a charge-transfer material, as well as methods thereof. Described herein are optical codes having anisotropic and/or isotropic regions within the film, which can be provided in a pattern that serves as an optical code.
    Type: Grant
    Filed: April 20, 2021
    Date of Patent: January 11, 2022
    Assignee: National Technology & Engineering Solutions of Sandia, LLC
    Inventors: Bryan James Kaehr, Joseph J. Reczek
  • Polarization-based coding/encryption using organic charge-transfer materials
    Patent number: 11151345
    Abstract: A charge-transfer material enables patterning approach where the polarization angle in stand-alone films can be precisely defined at the single pixel level and reconfigured following initial alignment. This capability enables new routes for non-binary information storage, retrieval, and intrinsic encryption, and it suggests future technologies such as photonic chips that can be reconfigured using non-contact patterning.
    Type: Grant
