CO exposure is a serious public health problem in the U. S. , causing both morbidity and mortality (lifetime mortality risk approximately 10 ). Sparse data from population-based CO exposure assessments indicate that approximately 10% of the U. S. population is exposed to CO above the National Ambient Air Quality Standard. No CO exposure measurement technology is available for affordable population-based CO exposure assessment studies. Two CO measuring devices, an occupational CO dosimeter (LOCD) and an indoor air quality (IAQ) passive sampler, were designed, developed, and tested both in the laboratories and field. Time-weighted-average CO exposure of the compact diffusion tube sampler containing a selective and non-regenerative palladium-molybdenum based CO sensor is quantified by using a simple spectrophotometer. Both devices are capable of measuring CO exposure precisely with relative standard deviation of less than 20% and with bias of less than 10%. Results indicated that the CO exposure distributions measured by LOCD has a precison of about +/-1 ppm.

Photon generating devices produce predetermined radiation spectral output and heat for a variety of applications including lighting and electric power generation, and provide photons to enhance chemical and physical reactions. Such a device comprises an emitter which contains metal oxides, means to heat the emitter sufficiently to produce large number of photons of a desired spectral output, and an optical means for directing the photons to various targets. In one embodiment, the device includes a thermal input device, a light pipe having a low emissivity, and an emitter coating of superemitter material which is thermally stimulated to emit radiation of a specific wavelength above a threshold temperature. An intermediate layer may be used to bond the emitter coating to the light pipe or other optical device where desired. Another embodiment comprises coating blackbody emitters onto transparent optical waveguides, such as light pipes, and heating the coating to emit photons into the light pipes which are directed to a target, and further comprises a means to select a particular target.

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.

A carbon monoxide (CO) detection system is connected into an anesthesia gas delivery system. The system comprises, among other things, a CO sensor unit containing an inexpensive, replaceable sensor that detects the presence of CO in anesthesia, an in-line adapter that exposes the detection unit to the main stream of the gas and can be placed in a variety of different locations along the gas stream and a side-stream adapter for the removal and analysis of gas stream samples using a CO sensor unit outside of the main gas stream. There is also apparatus capable of measuring the response of the sensors to CO exposure, and data acquisition and a data processing unit for storing, processing and displaying the CO sensor response data. In a preferred embodiment there is a carbon monoxide detection system comprising a detection unit including a sensor unit and a measurement unit. The sensor unit detects carbon monoxide based on the change or rate of change of the optical characteristics of the sensor unit.

The present invention provides very small low cost apparatus and method for determining the concentration and/or hazard from a target gas by means of optically monitoring one or more sensors that responds to carbon monoxide. The apparatus comprises a photon source optically coupled to the sensor and the photon intensity passing through the sensor is quantified by one or more photodiode(s) in a system, so that the photon flux is a function of at least one sensor's response to the target gas, e.g., transmits light through the sensor to the photodiode. The photocurrent from the photodiode is converted to a sensor reading value proportional to the optical characteristics of the sensors and is loaded into a microprocessor or other logic circuit. In the microprocessor, the sensor readings may be differentiated to determine the rate of change of the sensor readings and the total photons absorbed value may be used to calculate the CO concentration.

A superemissive combustion device of this invention comprises a porous distributive layer and an apparatus for delivering a fuel/oxidizer mixture to an upstream face of the porous distributive layer. A superemissive advanced emissive matrix in is disposed within an active flame zone downstream from the porous distributive layer. The emissive matrix is in the form of a three dimensional matrix of radiating bodies that is optically thin to electromagnetic radiation. The emissive matrix is either formed from or includes a coating of a superemissive material that is selected to emit photons within a predetermined wavelength range when thermally stimulated. The emitted photons are received by one or more photovoltaic cells disposed adjacent the matrix.
