Abstract: Apparatus and methods for detecting concealed personal security threats may comprise conventional mirrors and less conventional arrays of Hall-effect sensors and/or magnetometers, preferably at least two axis or three axis sensors or sensors mounted back-to-back. The concealed personal security threats may comprise, for example, sticky devices consisting of geographic position sensors for covertly broadcasting motor vehicle location data, of so-called Improvised Explosive Devices (IED's) which may be covertly or openly affixed to, for example, the undercarriages of motor vehicles using strong magnets and later exploded, the former giving away private location information, the latter causing damage to the motor vehicles to which they are affixed and sticky containers for hiding contraband among other “sticky devices.” Magnetic fields detected by, for example, arrays of Hall-effect sensors and the like may be quantified and stored in processor memory as a vehicle magnetic field signature.

Abstract: 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.

Abstract: Apparatus and methods for detecting concealed personal security threats may comprise conventional mirrors and less conventional arrays of Hall-effect sensors, soft iron cores, magnetometers and the like, preferably at least two axis sensors. The concealed personal security threats may comprise, for example, sticky devices consisting of geographic position sensors for covertly broadcasting motor vehicle location data, of so-called Improvised Explosive Devices (IED's) which may be covertly or openly affixed to, for example, the undercarriages of motor vehicles using strong magnets and later exploded, the former giving away private location information without the knowledge of a driver or passengers and the latter causing damage to the motor vehicles to which they are affixed and potentially harming a driver, passengers and nearby persons and sticky containers for hiding items among other sticky devices. A sticky container may be used to contain, for example, a vehicle ignition key or contraband.

Abstract: 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.
