  • Man down detector
    Patent number: 9269252
    Abstract: A man down indicator includes a gas detector which includes a motion sensor. A separate wearable element also includes a motion sensor. The element is wirelessly coupled to, and paired with, the detector. In responsive to a lack of sensed motion at both detector and the element, a pre-alarm condition is initiated for a predetermined period of time by circuitry carried by one of the detector, or the element. Unless interrupted, when the pre-alarm condition terminates, a man down alarm is generated.

  • Integrated IR source and acoustic detector for photoacoustic gas sensor
    Patent number: 8695402
    Abstract: A photoacoustic gas detector includes an integrated source, infrared filter and an acoustic sensor. The source, filter and acoustic sensor can be integrated onto one or more semiconductor substrates, such as silicon. Processing circuitry can also be integrated onto the substrate. Further, the source, filter and acoustic sensor can be integrated into a single component package, such as a metal can transistor package.
