  • Networked miniature chemical optical sensors
    Patent number: 6700484
    Abstract: A network for detecting a substance includes at least two detectors that are capable of transmitting a signal, and a remote station capable of receiving the signal. The detectors are adapted to detect a substance and transmit data that indicates the presence of that substance to the remote receiving station.
    Type: Grant
    Filed: December 7, 2000
    Date of Patent: March 2, 2004
    Assignee: Texas Instruments Incorporated
    Inventors: Dwight Urban Bartholomew, Diane L. Arbuthnot
  • Miniature chemical optical sensor in a can
    Publication number: 20020070364
    Abstract: A vapor detector is disclosed, that includes a chemically sensitive waveguide and a light detector coupled to the waveguide. The light detector is adapted to respond to light transmitted through the waveguide. Vapors reacting with the waveguide reflect light transmitted through the waveguide. The light detector recognizes changes in the transmitted light to identify the vapor that reacted with the waveguide.
    Type: Application

  • Wave-guided miniature spectrophotometer transducer
    Publication number: 20020071625
    Abstract: A spectrophotometer transducer is disclosed that includes a chemically sensitive wave-guiding thin film and a light detector coupled to the wave-guiding thin film. The light detector is adapted to respond to light transmitted through the wave-guiding thin film. Vapors reacting with the wave-guiding thin film reflect light transmitted through the wave-guiding thin film. The light detector recognizes changes in the transmitted light to identify the vapor that reacted with the wave-guiding thin film.
