Abstract: A system and methodology for the detection of threat substances is described. The detector system consists of a method to evaporate the sample into a primary separator and thermal release of trapped target materials into a secondary separator like conventional GC. The GC column is thermally ramped to elute all substances and the end of the column terminates into an atmospheric pressure chemical ionization source of an axial ion mobility spectrometer (AIMS). Both polarity ions are pulsed into a single construction separator tube at different timing. Their arrival time is detected on a collector plate, which allows registering their ion mobility spectra of both polarities for a single GC peak.

Abstract: A system and a method for measuring leakage current in an electrical transmission network. The system contains a plurality of electric current measurement devices distributed along the electrical transmission network and at least one central controller. The current measurement devices measure the electric current substantially continuously or repeatedly and report to the central controller. The central controller performs analysis of the measurements of the electric current along the transmission network and calculates the leakage current.

Abstract: A method of screening aircraft passengers and/or cargo comprising loading an aircraft with passengers, cargo or both, circulating air within the aircraft so that the air is in contact with the passengers and/or cargo, expelling some of the circulated air from the aircraft, diverting a portion of the air being expelled from the aircraft through a chemical filter configured to retained evidence of a target substance, and analyzing the chemical filter to detect the presence of a target substance within the aircraft.

Abstract: The present invention is directed to a system for screening the content of the air proximate to a target for the presence of one or more illicit substances by using a chemical detector, a metal detector and a radiation detector all houses within a portable detection unit that may be carried by hand to detect threat substances on a target. The system also comprises a support module that is coupled either wirelessly or though a conduit to the portable detection unit to support the operations of the portable detection unit by proving processing and analysis of the detected results and power. The system also comprises a vacuum source for drawing air proximate to the target into the portable detection unit for vaporization and analysis. The vacuum source may be within the support module and drawing air through a hose in the conduit, or may be within the portable detection unit itself.

Abstract: The present invention is a transportable portal for screening a target, which may be a person, standing or placed inside the portal. It employs two walls with air ducts in the walls, usually two ducts per wall running from the bottom to the top of each wall, and having a number of air intakes spaced along the height of the wall. A blower module blows air downward on the target to dislodge particles and vapor, which are drawn in the air ducts and analyzed by a detection module. Each detection module may have a pre-concentrator with a nano-platinum surface for collecting and pyrolyzing samples, and chemical, optical and radiation detectors for detecting illicit materials. The portal may be disassembled or reassembled by two people using hand tools in less than one hour and then placed in a space of less than one cubic meter for transport.
