  • Fiber optic sensors for gas turbine control
    Patent number: 6599028
    Abstract: An apparatus for detecting flashback occurrences in a premixed combustor system having at least one fuel nozzle includes at least one photodetector and at least one fiber optic element coupled between the at least one photodetector and a test region of the combustor system wherein a respective flame of the fuel nozzle is not present under normal operating conditions. A signal processor monitors a signal of the photodetector. The fiber optic element can include at least one optical fiber positioned within a protective tube. The fiber optic element can include two fiber optic elements coupled to the test region. The optical fiber and the protective tube can have lengths sufficient to situate the photodetector outside of an engine compartment.
    Type: Grant
    Filed: June 9, 1999
    Date of Patent: July 29, 2003
    Assignee: General Electric Company

  • Audience measurement system employing local time coincidence coding
    Patent number: 6519769
    Abstract: The present invention provides a system for recording a viewer's television viewership habits. Sensors monitor the audio signal, synchronization signal, and video signal emanating from the television. A time coincidence channel tag is mixed with the transmitted television audio or video signal at a dwelling by a master unit. Then by matching the channel tag of the viewed channel with the channel tag, an accurate identification of the viewed channel can be made.

    Filed: November 9, 1998
    Date of Patent: February 11, 2003
    Assignee: General Electric Company
    Inventors: Michael Robert Hopple, Richard Louis Frey, Donald Thomas McGrath, Robert John Dunki-Jacobs
  • Television viewership monitoring system employing audio channel and synchronization information
    Patent number: 6112053
    Abstract: The present invention provides an system, apparatus, and method of recording a viewer's television viewership habits. Sensors passively monitor the audio signal and video signal emanating from the television. By matching the audio signal in the source and emanating from the television and by matching television frame synchronization signal and the television source synchronization signal an unambiguous identification of the viewed channel is made.
