Benjamin T Marshall 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).

  • Gas filter correlation radiometry method and system using a dissimilar gas to detect a target gas
    Patent number: 8289518
    Abstract: A Gas Filter Correlation Radiometer (GFCR) system and methods of using same are provided. The system's GFCR instrument includes a gas cell. A gas in the gas cell has a chemical composition that is different than that of a target gas in an atmospheric region being examined by the GFCR instrument. The gas included in the gas cell also possesses light absorption features with a portion thereof being at least partially correlated with light absorption features of the target gas. Measurement viewing(s) made with the GFCR instrument provide for at least one positive correlation for the portion of the at least partially correlated features so that the GFCR instrument generates a signal indicative thereof used in a gas filter correlation radiometry application.
