Abstract: Described herein is a rapid coupled enzymatic assay to detect polycyclic aromatic hydrocarbon (PAH) compounds in samples. The method uses a detection composition that includes: a buffered solution comprising NADH; naphthalene dioxygenase, naphthalene 1,2-dihydroxy-1,2-dihydronaphthalene dehydrogenase, and 1,2-dihydroxynaphthalene dioxygenase. The presence of PAH is determined by noting a color change of the detection composition, either visually or spectrophotometrically.

Abstract: There is provided a portable, lightweight, trauma treatment and patient monitoring device. The device comprises a base having a top surface and a pair of housings each having an inner surface. The housings are in pivotal communication with the base to enable selective articulation between a closed orientation and an open orientation. In the closed orientation, the inner surfaces of the housings are substantially parallel to the top surface of the base. In the open orientation, the pair of housings are in spaced opposed relation to each other and the inner surfaces are substantially perpendicular to the top surface of the base. The device also includes at least one bay located within at least one of the pair of housings. The bay is capable of receiving at least one medical monitoring/treatment device.

Abstract: A self-tightening device for fastening two structures together includes a female component and a male component where the female component is capable of receiving the male component. The female component includes a moveable member, an energy storing mechanism and a retaining mechanism. The movable member is movable between an unlocked position and a locked position. The energy storing mechanism has stored energy for causing the moveable member to move from the unlocked to locked position when the energy in the energy-storing mechanism is released. The retaining mechanism holds the energy-storing mechanism in the stored-energy state until the retaining mechanism is released.

Abstract: A storage assembly has a plurality of panels that are assembled to form a plurality of storage spaces, a plurality of connectors for coupling adjacent panels to form the plurality of storage spaces, and at least one tray positioned inside one of the storage spaces. Each connector has a generally circular body having a plurality of spaced-apart scalloped regions, with a recess provided at each of the locations of the scalloped regions. The storage system includes a caster having a wheel and a caster frame. The caster frame has a body, a bore provided therethrough for receiving the wheel, and at least two spaced-apart passages formed in the circumference of the body.

Abstract: Embodiments of the present invention are directed to a portable computer, such as a laptop or notebook computer, a subnotebook computer, a personal digital assistant, a wireless phone or the like, that can be set up in a closed configuration, a laptop configuration or a tablet configuration. The portable computer may include a base unit having a primary input device, such as a keyboard or pointing device, and a display unit having a display device. The base unit and the display unit may be coupled so that the display unit can be moved relative to the base unit to place the portable computer in a desired configuration.

Abstract: A headset adapted for use with a cellular telephone comprises an earphone shaped to fit in the ear of a user, an earphone arm extending from the earphone to an earphone arm pivot end, a support protrusion extending from the earphone arm pivot end to rest under the ear of the user when wearing the headset, a telescoping arm extending from a microphone to a microphone arm pivot end, the microphone arm pivot end pivotally connected to the earphone arm, the telescoping arm having an arcuate shape.

Abstract: A modular shelving assembly has at least three spaced poles, each having a connector, a first post unit and a second post unit. Each post unit has first and second opposing ends, with a first protrusion extending radially inwardly from the hollow interior surface of the first post unit adjacent the first end thereof, and a second protrusion extending radially inwardly from the hollow interior surface of the second post unit adjacent the second end thereof. Each connector has first and second opposing ends, a first track provided adjacent the first end of the connector and a second track provided adjacent the second end of the connector. Each of the first and second tracks has a leg portion extending from one of the first or second end of the connector, and a foot extending from the leg portion.

Abstract: A dress or clothing form includes a sheet metal back to which are attached a plurality of reinforcing strips. A support rod is carried on one of the reinforcing strips and on the back. Leg supports are attached to the back to which are attached a pair of flat leg panels. Front and back molded plastic body panels are secured by fasteners to the metal back and similar molded front and back leg panels are secured to the flat leg panels. The support rod includes a large diameter portion at its top which includes a tapered surface. This surface mates with a socket on a support arm attached to a stand for supporting the form at the desired height. The stand includes telescoping members each including a rack with one member including a gas spring connected to a pinion positioned between the racks. The gas spring is arranged to essentially balance the weight of the dress form and garment so that a worker can move it up and down with little effort.

Abstract: Disclosed is a novel process and product involving the manufacture in advantageously high yields of imidazole compounds corresponding to the general formula: ##STR1## wherein a preferred embodiment of the process comprises contacting a diamine salt of the formula ##STR2## with a biscarbonyl compound of the structure ##STR3## in an acid medium, wherein R, R.sub.1 and R.sub.2 each represents hydrogen or any group which does not hinder the cyclization reaction or lead to degradation of the reactants or imidazole products, and A.sup.- is an anion equivalent such as that of mineral acids, sulfonic acids and carboxylic acids.

Abstract: Containers or pods for photographic processing material, having strong seals along certain edge areas, and relatively weaker seals along other edge areas. The weaker seals are designed to open and distribute material over a sheet of film and/or paper when pressure is applied within a camera. The weak seal material is a thermoplastic crosslinked homopolymer of a norbornene compound having the structure: ##STR1## wherein R' is selected from the group consisting of a hydrogen atom, a monovalent aliphatic group of from 1 to 4 carbons, and a phenyl group, R" is selected from the group consisting of a hydrogen atom and a monovalent aliphatic group of from 1 to 2 carbons, and n is 0 to 3. Seals made with these homopolymers are highly resistant to the dissolving action of aromatic alcohols such as benzyl alcohol.
