  • Patent number: 10466219
    Abstract: A vapor sensor comprises a housing with an inlet opening in fluid communication with a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to an output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.

  • Patent number: 9658198
    Abstract: A method for identifying and quantitatively analyzing an unknown organic compound in a gaseous medium. More specifically, the method provides a gas sensor array (120a, 120b, 120c, 120d) coupled to a diluting channeling gas inlet (105) with a honeycomb configuration. Each sensor (120a, 120b, 120c, 120d) in the array receives the test gas after successive dilutions. Detected gas are identified by correlating the responses of each sensor with its associated dilution.
