An enclosure for a gas detector including an easily removable and replaceable battery/sensor holder and a battery absence indicator. The enclosure includes a flat first panel adapted to be fastened into a ceiling, a second panel spaced from the first panel to contain the gas detecting apparatus and a sidewall closing between the edges of the panels. A specially configured opening is provided to allow sound from an audio alarm to exit the enclosure. Another opening in the second side panel is configured to receive and retain a battery holder through a cooperating bayonet type arrangement of radial protrusions on the holder and notches in the sides of the opening. A tube is contained in the opening in such a way as to permit the tube to extend when the holder is removed to signal the absence of the holder. The tube is pushed back into the enclosure when the battery/sensor holder is inserted. One or more protrusions may house a gas detection cell so that the cell is automatically inserted between a light emitting means and a light detecting means when the batter/sensor holder is inserted.

The present invention is a new sensor system with catalyst for control and one with a dummy catalyst. An apparatus and method for rapidly determining the concentration of CO, water vapor, and temperature. One of the major reasons to rapidly determine a small but sudden rise CO is for fire detection. The combination of the CO, followed by rapid relative humidity rise is a clear indication of possible fire or an appliance malfunction, blocked flu or other combustion process gone awry. If the incident is accompanied by ions or particles that would be smoke from a fire. The signal from the CO determined by numerically compensating for humidity changes. Any one or two parameters could cause an increase the sensitivity of the other in a fire detector such as combination CO, relative humidity, temperature and smoke detector. Another application for rapid CO detection is in a vehicle to protect the occupants from a catastrophic CO event. The preferred embodiment by means of optically monitoring the control and CO responding sensors that respond to the CO by means monitoring the optical change to the humidity in one and humidity and CO in the other and provide a means to remove the humidity.

The present invention relates to a biomimetic sensor for detecting the presence of airborne toxins, such as carbon monoxide, mercury, ethylene oxide, volatile organic materials, and hydrogen sulfide. The biomimetic sensor, which has a functional life of at least one year, comprises a porous, semi-transparent substrate into which is impregnated a self-regenerating chemical sensor reagent. The response of the biomimetic sensor mimics the human response to such toxins, with respect to sensitivity and affinity. The extended functional lifetime of the biomimetic sensor and the mimicking of the human response to the toxins are achieved by the use of a molecular encapsulant that encapsulates at least one component of the chemical sensor reagent.
