| 20080309488 | PASSIVE MICROWAVE FIRE AND INTRUSION DETECTION SYSTEM - 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 array can be used to provide a plurality of frequency ranges that can be detected. In an interior installation, one or more receiver array can be placed inside a wall. 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 through a non-metallic wall. | 12-18-2008 |
| 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 |
| 20100069782 | Passive Microwave Assessment of Human Body Core to Surface Temperature Gradients and Basal Metabolic Rate - A passive microwave thermography apparatus uses passive microwave antennas designed for operation, for example, at WARC protected frequencies of 1.400 to 1.427 GHz and 2.690 to 2.70 GHz (for core body gradient temperature measurement) and 10.68 to 10.700 GHz or higher microwave frequency (for surface body gradient temperature measurement) and a related directional antenna or antenna array to measure microwave radiation emanating from an animal, especially, a human body. The antennae may be radially directed toward a point within or on the surface of a human body for comparison with known temperature distribution data for that point and a given ambient temperature. Each frequency band may provide a plurality of adjacent noise measuring channels for measuring microwave noise naturally emitted by the human body. The apparatus measures short-term changes in, for example, core and body surface temperatures to establish a basal metabolic rate. Changes in core body temperature may be stimulated by the administration of food or certain organic and drug-related substances or stress to induce a change in basal metabolic rate over time. These changes correlate directly with a human subject's metabolism rate at rest and under certain dietary constraints and can be used to determine courses of treatment for obesity, metabolic disease, and other disorders. The apparatus can also be used to remotely monitor patients and subjects without physical contact. | 03-18-2010 |
| 20100079282 | PASSIVE MICROWAVE SPEED AND INTRUSION DETECTION SYSTEM - A passive microwave receiver, receiving a WARC protected frequency of 1420 MHz may be used for fire, temperature speed detection 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 automobiles and intruders via black box emission. A passive microwave detector may be used at a highway where the highway intersects an associated antenna lobe for a distance, mounted on a wall or pole and have line-of-sight view of an intruder or automobile. | 04-01-2010 |

| 20110155397 | PASSIVE MICROWAVE SYSTEM AND METHOD FOR PROTECTING A STRUCTURE FROM FIRE THREATS - An automatic fire suppression system used to provide protection of window glass and other structural elements in aircraft terminals which are exposed to exterior fires caused by natural, accidental, or intentional events comprises a directional passive microwave receiver, a central processor for processing received microwave signals over time and comparing the received signals over time with thermal event signatures stored in memory to selectively actuate a sprinkler system for protecting the window glass in the vicinity of an identified fire event. The memory may further store a model of the aircraft terminal, and the processor utilizes a fire dynamics simulator to simulate a thermal event at the terminal. A related fire suppression process involves the detection of incipient fires through an array of exterior passive microwave heat sensor fire detectors connected to an electronic control processor which identify zones such as 30 to 100 linear foot zones of exterior glass surface and automatically initiates an array of quenching sprinkler heads applying water to the exposed surfaces of glass and other structural elements in response to detection of an identified fire event by its signature. | 06-30-2011 |
