Glenn Calvert 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).

  • Devices and methods for determining the amount of energy absorbed during irradiation
    Patent number: 6979829
    Abstract: Devices and methods are disclosed for determining the amount of energy absorbed during irradiation. Such devices comprise a material that absorbs radiation in a quantifiable manner and a cooling agent to maintain the temperature of that material within a predetermined range, and may be used to determine the amount of energy absorbed during irradiation, for example during sterilization of a biological material.
    Type: Grant
    Filed: April 23, 2003
    Date of Patent: December 27, 2005
    Assignee: Clearant Inc.
    Inventors: Glenn Calvert, David Clark, Martin J. MacPhee, Randall Kent, Anna L. McBain, Bryant O. Pearce
  • Methods for sterilizing biological materials by irradiation over a temperature gradient
    Patent number: 6908591
    Abstract: Methods are disclosed for sterilizing tissue to reduce the level of one or more active biological contaminants or pathogens therein, such as viruses, bacteria, (including inter- and intracellular bacteria, such as mycoplasmas, ureaplasmas, nanobacteria, chlamydia, rickettsias), yeasts, molds, fungi, spores, prions or similar agents responsible, alone or in combination, for TSEs and/or single or multicellular parasites. The methods involve sterilizing one or more tissues with irradiation.
