Patents by Inventor Grant Plummer

Grant Plummer 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).

  • Processing system for remote chemical identification
    Publication number: 20050154539
    Abstract: A fourth embodiment of the present invention is a method of generating a temperature compensated absorbance spectrum. The method includes the steps of: a. providing a sample spectrum and an estimated temperature of a backdrop object; b. from a set of known temperature spectra related to a known background temperature, selecting at least two known temperature spectra representing a background temperature above and below the estimated temperature; c. comparing the sample spectrum to the known temperature spectra in order to determine a sample background spectrum; and d. calculating an absorbance spectrum from the sample spectrum and the background spectrum.
    Type: Application
