Appl. No.:

10/194477

Inventors:

Yu Jin Li - El Monte CA 91731

International Classification:

B60J 1100

US Classification:

296 951, 296136, 16037021

Abstract:

A foldable vehicle window shading device includes a central hub having a receiving cavity, and a plurality of folding arms radially extended from the central hub, a plurality of elongated elements extended from the central hub to the folding arms respectively, and an awning shelter supported by the folding arms for sheltering the vehicle window. Each of the folding arms includes a plurality of tubular members wherein a tension portion of the respective elongated element is slidably passed through the tubular members in such a manner that when shortening the length of each tension portion of the elongated elements, the tubular members of each folding arm are tensionally coupled with each other ends to ends to outwardly extend the folding arm from the central hub, so as to tensionally stretch out the awning shelter.

Abstract:

This disclosure relates to compositions and methods of their use in detection and identification of a chordopoxvirus in a sample, such as diagnosis of an infection in a subject. The compositions and methods allow for detection and identification of all non-avian low-GC content chordopoxviruses, identification of most known high-GC content chordopoxvirus, and species-specific detection of Canarypox virus, Fowlpox virus, and Sealpox virus.

US Classification:

482128, 482133

Abstract:

A chair-like exercising apparatus comprises a back, a seat, front legs, rear legs, and resistance element(s) which provide a broad range of resistance force adjustable by the user for the back extension exercise. The chair back pivotally connects to the rear legs directly, and pivotally connects to the front legs or rear legs through the resistance element(s). The resistance element comprises a compress-coil-spring cylinders (or constant-force-spring devices) and the cylinder holders (or the device holders). The resistance level of the back extension exercise is adjusted by switching the interchangeable compress-coil-spring cylinders (or constant-force-spring devices) of appropriate loads inside the cylinder holders (or device holders). A user sits on the chair and sway backward to perform back extension exercise after selecting an appropriate resistance level based on his/her physical condition. The apparatus is simple, affordable and can be used as a regular chair in its locked position. A regular back extension exercise with proper resistance force strengthens the low back muscles (erector spinae), improves and prevents the low back pain symptoms.

Abstract:

A toothbrush with pressurized toothpaste dispenser for dispensing toothpaste by pressing a release valve. The inventive device includes a toothbrush having a handle portion and a brushing portion. The handle portion has a hollow interior with a paste conduit extending from it into the brushing portion. The paste conduit is in communication with a paste nozzle that extends outwardly of the brushing portion. The brushing portion has a plurality of bristles that extend outwardly from it and surround the paste nozzle. The hollow interior of the handle portion of the toothbrush is adapted to receive toothpaste. The interior has a forward biasing portion that urges toothpaste held in the hollow interior of the handle portion into the paste conduit. A paste dispensing valve is in communication with the paste conduit.

Abstract:

A real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay that utilizes multiplex primers and probes with degenerate nucleotides to detect divergent species of lyssavirus is described. The probes used in the RT-PCR assay target a highly conserved region at the 5′ end of the lyssavirus genome and are modified with either a minor groove binder (MGB) or locked nucleic acid (LNA) nucleotides to increase their melting temperature. The described assay detects all known lyssavirus species with a sensitivity and specificity superior to traditional hemi-nested PCR and the direct fluorescent antibody (DFA) test.

Inventors:

Yu LI - Johns Creek GA, US

International Classification:

A61M 3/02

Abstract:

A portable contact-washing device allows a user to wear a single-use finger cover for contact washing of rectal area using water that is delivered to the finger pad area through micro tubing by a mini water pump. This contact wash uses a limited amount of water for a sufficient hygienic wash to the rectal area after a bowel movement without causing irritation which is often associated of using toilet paper. The contact washing process is efficient and requires a small volume of water, and the contact-washing device is highly portable and easy to use outside of home. The finger cover may be made of biodegradable material and will be discarded after the use.
