  • Magnetically controlled gas detectors
    Patent number: 9557306
    Abstract: Non-contact magnetic, optical or RF control elements can be used to control various operational aspects, or parameters of a gas detector. The detector can be placed in a low current, or sleep, mode wherein the operational life-time is not reduced by the duration of the sleep mode. Instructions can be coupled to the detector magnetically, optically, or via RF to alter set points or other operating parameters. Information as to bump tests can also be coupled to the detector.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: January 31, 2017
    Assignee: Honeywell International Inc.
    Inventors: Clive Warden Kennard, Stephen D. Worthington, Brandon Eble, Tak G. Saruwatari, Sean E. Stinson
  • Detector with integrated sensor platform
    Patent number: 9368012
    Abstract: An integrated system platform includes a sensor containing an embedded microcontroller and associated circuitry for providing safety critical functionality. Signal conditioning circuitry is coupled to the sensor along with gas concentration determining circuitry, alarm status circuitry and fault status evaluation circuitry. Wherein the sensor is operational with a main control module and at least one alarm output device.
