International Classification:

A61M 1500

US Classification:

12820315, 12820312, 12820323

Abstract:

A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from the larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater air flow and powder dispersion, without any increased effort by the patient.

International Classification:

F23R003/40

US Classification:

60775, 60777, 60723, 60 395, 60 3955, 95 54

Abstract:

Provided is a combustion engine having a combustion chamber. The combustion engine comprises an engine housing having an air intake port, a mixed conductor, a water intake port, an exhaust turbine and a hydrogen compressor assembly. The air intake port provides air to the mixed conductor which provides an oxygen-pure fraction of air to the combustion chamber by conducting oxygen ions in the air from a retentate side to a permeate side when the oxygen partial pressure on the permeate side is less than that on the retentate side. The water intake port provides water to the combustion chamber for combustion with hydrocarbon fuel and the oxygen-pure fraction of the air to produce exhaust fluid. The exhaust fluid expands in the exhaust turbine causing the turbine rotor to rotate producing mechanical energy. The hydrogen compressor assembly extracts hydrogen from the exhaust fluid and provides hydrogen to the exhaust turbine.

International Classification:

A47B 95/00

US Classification:

2483451, 293128

Abstract:

A padding protective arrangement for furniture includes an elastic connective member and a plurality of cushioning pads. The elastic connective member has first and second end connecting portions, and a connector provided on the first end connecting portions. Each of the cushioning pads has a thickness larger than that of the elastic connective member, and a through mounting slot formed on the cushioning pad, wherein the elastic connective member is arranged to penetrate the cushioning pads at the respective mounting slot in such a manner that the first and the second end connecting portions are detachably connecting with each other by the connector to define a cushioning loop within the elastic connective member and the cushioning pads, wherein the cushioning loop is arranged to fittedly encircle a rim portion of the furniture for providing a cushion effect to absorb shock when a user accidentally hits the rim of the furniture.

International Classification:

G01R 31/02

US Classification:

324760, 324755, 361704

Abstract:

An electronic device burn-in thermal management system includes Burn-in-Boards (BIBs) with quick disconnect connectors to easily connect and disconnect the BIB () from liquid cooling lines () in a rack that can hold one or more BIBs. The BIB () may include liquid cooled heat sinks () embedded in the BIB sockets () in order to cool the electronic devices undergoing burn-in test (DUT). This arrangement allows the DUT to make positive thermal contact with the heat sink when it is mounted in the BIB socket and allows the user to remove the BIB () quickly after completing a test to load the next batch of DUTs onto a separate BIB.
