20090252196 | Passive Microwave Fire and Intrusion Detection System Including Black Body and Spectral Emission at the Hydrogen, Hydroxyl and Hydrogen Chloride Lines - A passive microwave receiver array, operating in the one meter to sub-millimeter wavelengths range and including an internationally protected range of frequencies of varying bandwidth, may be used for fire and intrusion detection. One or more receiver arrays can be used to provide a plurality of frequency ranges that can be detected. In an interior installation, one or more receiver arrays can be placed inside a wall made of non-metallic substance and capable of passively receiving frequencies at less than 3 GHz. In other embodiments, the receiver and array can be in the form of a hand-held or wearable device. This method and apparatus achieves high performance by exploiting conventional low noise amplification block conversion circuits and provides the detection of thermal signals through clear, smoky, misty, or environmentally untenable conditions as well as the detection of fire and intrusion events via black box or spectral line emission at hydrogen, hydroxyl radical or HCl spectral line emission where an HCl spectral line detector may be mounted on a wall or pole and have line-of-sight view of an intruder or fire. | 10-08-2009 |
