Patents by Inventor Marye A. Fox

Marye A. Fox 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).

  • Optoelectric memories with photoconductive thin films
    Patent number: 5424974
    Abstract: Methods and apparatii are described for information storage in photoconductive film of single layer composition by irradiation of memory elements simultaneously with application of an electric field. Information is stored as trapped charge accumulations in the film when the irradiation is removed, but trapped charge can be released by subsequent irradiation. Repeated information storage, followed by erasure, returns the films to their original state without degradation.
    Type: Grant
    Filed: July 5, 1994
    Date of Patent: June 13, 1995
    Assignee: Board of Regents, The University of Texas System
    Inventors: Chongyang Liu, Horng-long Pan, Allen J. Bard, Marye A. Fox

  • Multielectrode photoelectrochemical cell for unassisted photocatalysis and photosynthesis
    Patent number: 4793910
    Abstract: A multielectrode photoelectrochemical cell in which at least contains two bipolar electrode panels for photoelectrochemical reactions such as water photolysis to produce H.sub.2 O.sub.2 without external bias. In one embodiment of the present invention, a bipolar TiO.sub.2 /Pt multielectrode photoelectrochemical cell was fabricated with five panels in series. The cell permitted unassisted photolytic (Xe lamp) water splitting to produce H.sub.2 and O.sub.2 with H.sub.2 O.sub.2 molar ratio of 2.4/1.
