A detector for detecting vapors emitted from analytes includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume therebetween. The pump communicates with the housing for moving a carrier sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the analyte delivered by the carrier as the carrier passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a detector, and a convertor assembly.

A portal is provided with a detector for detecting trace amounts of substances of interest that may be retained on the surface or interior of a vehicular subject. The portal relies upon the continuous process by which microscopic flakes of dust, dirt, pollen, and other surface and interior contaminants as well as adsorbed analyte media and analyte vapors continuously separate from the surface of vehicular subjects and escape from the interior of vehicular subjects. The portal further leverages the existence of a vehicular thermal plume consisting of a layer of warm air adjacent to the vehicular subject. The warm air rises in the cooler surrounding air and transports the microscopic flakes of surface contaminants, desorbed analyte, and analyte vapors upwardly. The portal capitalizes on this phenomenon by providing at least a partial enclosure with a funnel-shaped collector above the vehicular subject. A low speed flow of relatively dense cool air may be introduced into the portal to buoyantly lift the warmer air of the vehicular thermal plume upwardly. The air stream defined by the vehicular thermal plume and the contaminant particles, analyte media, and analyte vapors therein moves to a trap in the funnel-shaped collector above the portal. The trap cooperates with a detector for detecting the presence of molecules of interest.

A detector for detecting vapors emitted from energetic compounds includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume there between. The pump communicates with the housing for moving a carrier gas sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the energetic compound delivered by the carrier gas as the carrier gas passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a light detector, and a convertor assembly.

An adapter device for downloading stored data from a pager device to a digital computer. A pager device with holster includes an interface circuit board with transmission circuitry, either wired or wireless, for downloading logic level signal, data stored in the pager to a host digital computer for input via the RS-232C interconnect.
