Abstract: Disclosed is a supportive chair for sitting comfortably at low heights above and relative to the ground. Preferably, the chair comprises a primary seating surface and a secondary seating surface curving around the rear of the primary seating surface to provide additional support for the user. It is preferred that the secondary seating surface be inwardly and downwardly sloped and provide a low lateral boundary for the user, thereby promoting proper alignment of the buttocks on the primary seating surface. Thus, the chair raises the buttocks and hips of the user off of the seating level, creating a relative height difference between the hips and legs. This raising of the hips relative to the legs creates a sitting posture that promotes vertical back alignment. As a result, the user is able to comfortably maintain this position with a reduced amount of back muscle strain, allowing prolonged comfortable seating periods.

Abstract: The present invention is an interface between a piece of baggage and a preconcentrator. The baggage-preconcentrator interface is able be secured to the opening in the baggage, such as an opening created by a zipper. The baggage-preconcentrator interface provides a convenient entry point from which to extract air from the interior of baggage. The shape of such interface corresponds to that of the preconcentrator, which collects constituents of air. The preconcentrator is inserted into the baggage-preconcentrator interface and an air sample is extracted from the interior of the baggage and through both the interface and the preconcentrator. As the air is extracted, the constituents of air collect in the preconcentrator. After collecting the constituents, the preconcentrator is inserted into a testing unit capable of detecting trace amounts of explosives, such as an ion trap mobility spectrometer. The testing unit analyzes the constituents and determines whether any of them are explosive.

Abstract: The present invention is a novel collection device that allows constituents of air to collect on a test strip included within the collection device. Specifically, the collector allows a removable test strip to be inserted in the collector while an air sample passes therethrough. Thereafter, the test strip is removed from the collector and analyzed to determine the constituents of air that passed through the test strip and collector. When using the collector to inspect for trace amounts of explosives within a piece of baggage, the collector is connected to a baggage-collector interface because the shape of the baggage-collector interface corresponds to that of the collector. The baggage-collector interface is secured to the baggage and an air sample is extracted from the interior of the baggage and through both the interface and the collector, including the test strip. As the air is extracted, the constituents of air collect on the test strip.
