A system including at least one detector and a central station in two-way communication with the detector is provided. The detector can include an ambient condition sensing element, a motion sensor, control circuitry, and two-way communications hardware. The control circuitry can determine an alarm event based on a first signal received from the ambient condition sensing element and can transmit an alarm signal to the communications hardware during the alarm event. The control circuitry can also determine a man-down event based on a second signal received from the motion sensor and transmit a man-down alarm signal to the communications hardware during the man-down event. The two-way communications hardware can transmit at least one of the gas alarm signal and the man-down alarm signal to a remote location, and the two-way communications hardware can receive a status inquiry from the remote location.

Systems and methods for robust man-down alarms

A sensor system having an analyte modulator, detector and a pump. The concentration of an analyte sample may be modulated at one time constant. The detector may have an output with a drift at another time constant. The one time constant may be shorter than the latter time constant. The latter time constant may be substantially removed from the detector output with a discriminator. A reservoir may receive high concentrations of analyte from the modulator, before analyte is forwarded to the detector and pump via analyte conveyance lines and valving. The modulation or pre-concentration of analyte in the sensor system may entail shorter times and smaller volumes than those needed by the detector. Such mismatches may be alleviated via accumulation of analyte in the reservoir prior to being forwarded to the detector.

A removable utility attachment apparatus for use with a conventional ironing board whereby said apparatus provides multiple storage compartments in which safety pins, straight pins, clothes pins, buttons, and various other ironing accessories may be stored for easy access. The apparatus also provides a hanger bar below the ironing board surface upon which clothes hangers may be hung.
