International Classification:

E05C 1754

US Classification:

292339, 292262, 292DIG 15, 16 82

Abstract:

The invention relates to an apparatus for holding a door. The apparatus includes a door mounting plate configured to be mounted on the door. The door mounting plate is arranged to extend perpendicularly from the door and includes a door binding portion. The apparatus further includes a rigid body member arranged to be coupled to a floor and to extend perpendicularly from the floor wherein the body member is substantially immovable by a force exerted by the door. The apparatus additionally includes a locking member coupled to the body member. The locking member is disposed substantially perpendicular to the body member and has a locking member binding end configured to engage with the door binding portion.

H02H 9/08

US Classification:

361 939

Abstract:

A load current is limited to a safe level with a current protection logic circuit within a first selected interval after detection of a fault condition. The current protection logic circuit returns the load current to a normal level within a second selected interval after correction of the fault condition, wherein said safe level is less than one half of the normal level. The current protection logic circuit is a feature of a high side driver comprising at least two source drivers, each source driver being configured to switch an electrical load to a common power supply, and comprising a respective current protection logic circuit.

Appl. No.:

9/316971

Inventors:

David Truong - San Jose CA

Assignee:

International Business Technology Corporation - San Jose CA

International Classification:

A62C 502

US Classification:

239310

Abstract:

Methods and apparatus for generating a small, maneuverable stream of filtered fluid without benefit of a pump or electrical power are disclosed. According to one aspect of the present invention, a spray nozzle apparatus for dispensing a maneuverable stream of fluid, that originates from a fluid source at a first pressure includes an adapter assembly, a nozzle subassembly, and a flexible tubing. The adapter assembly is mechanically coupled to the fluid source, and is arranged to allow the fluid to flow from the fluid source through the adapter assembly. The nozzle subassembly dispenses the fluid at a second pressure, and includes a fluid intake end and a fluid dispensing end. The fluid dispensing end allows the fluid to flow therethrough in a small, stream-like configuration at the second pressure, and is in fluid communication with the adapter assembly. The flexible tubing allows the fluid to flow through, and is coupled to the fluid intake end of the nozzle subassembly. In one embodiment, the spray nozzle apparatus includes a filter that is in fluid communication with the flexible tubing and the adapter assembly.

Appl. No.:

8/608518

Inventors:

David Truong - San Jose CA

Assignee:

International Business & Technology Corporation - San Jose CA

International Classification:

E05C 304

US Classification:

292202

Abstract:

The present invention relates, in one embodiment, to an apparatus for holding a door. The apparatus includes a body member and a blocking member rotatably coupled to the body member. The coupling is such that when the body member is positioned vertically in front of the door, the blocking member is disposed in one of a first blocking position and a second blocking position. The blocking member, in the first blocking position, contacts the door to hold the door at a first predefined position. The apparatus, when the blocking member is in the second blocking position, contacts the door to hold the door at a second predefined position. The door is opened further in the second predefined position than in the first predefined position.
