US Patent:

7629067, Dec 8, 2009

Filed:

May 18, 2007

Appl. No.:

11/750833

Inventors:

Clint A. Beliveau - Bend OR, US
Scott C. Elliot - Bend OR, US
Vernon Wade Popham - Bend OR, US

Assignee:

Idatech, LLC - Bend OR

International Classification:

H01M 8/04
G01M 3/04
G08B 21/00

US Classification:

429 22, 73 405 R, 340605

Abstract:

Liquid leak detection systems, and fuel cell systems and hydrogen-producing fuel processing systems containing the same. The liquid leak detection systems are adapted to detect liquid leaks from the fuel cell and/or fuel processing systems and to respond thereto, such as by interrupting the delivery of liquid reactants, by generating an alert, by transitioning the fuel processing system to a different operating state, and/or by shutting down the fuel processing and/or fuel cell system. The liquid leak detection systems may include a controller and at least one liquid detector, and in some embodiments may include a cover. In some embodiments, the liquid detector includes a signal emitter and a signal detector. In some embodiments, the liquid detector includes at least a pair of spaced-apart conductive members that nominally define an open circuit. In some embodiments, the cover is adapted to repel water and/or includes conductive particulate.

Filed:

May 15, 2000

Appl. No.:

09/571956

Inventors:

Clint A. Beliveau - Beaverton OR
Wallace D. Doeling - Hillsboro OR

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H05K 710

US Classification:

361767, 361795, 361764, 174255, 257723, 257703

Abstract:

A printed circuit board structure is provided where there is a circuitized dielectric substrate having a plurality of signal traces thereon. The circuitized substrate has first and second opposite faces. An ASIC chip assembly is mounted on the first face and connected to the surface by solder connections. Preferably, the ASIC chip assembly is mounted on the substrate as an IC chip mounted on a chip carrier with the chip carrier being mounted to the circuit board by solder connections, preferably in the form of a ball grid array. In one embodiment, a discrete signal termination device is provided which is disposed on the second face of the circuitized substrate directly opposite the ASIC chip assembly. In another embodiment, a discrete signal termination device is disposed between the ASIC chip assembly and the printed circuit board. The signal termination device includes a plurality of planar resistors embedded in a dielectric material with the resistors being electrically connected to the signal lines on the circuitized substrate, preferably by solder connections, again in the form of a ball grid array.
