Title: Electrochemical fuel cell stack with an improved compression assembly
Inventor: RONNE JOEL A
IPC: H01M8/04
Filed: 1998-07-16
Granted: 2008-01-29
Abstract: An electrochemical fuel cell stack with an improved compression assembly comprises a tension member which is electrically non-conductive and preferably non--metallic. The tension member can be made from a composite material which has similar expansion and contraction properties as the stack materials, thereby reducing undesirable fluctuations in the compressive force applied to the stack. An improved apparatus for securing the improved tension member to the rest of the compression assembly is also provided. Preferred embodiments of an improved compression assembly employ a collet and wedges to grip the tension member and compress a resilient member which imparts a tensile force to the tension member and a compressive force to the fuel cell assemblies. In other embodiments, an improved compression assembly employs a unitary resilient member and fastener in combination with a tension member. The improved apparatus is easier to assemble in high speed manufacturing processes because the compression assembly can be assembled or installed using the same machinery which is used to compress the stack in one fixturing because the compression assembly is assembled by being stacked in essentially the same direction as the other fuel cell components. An improved method of assembling a compression assembly for an electrochemical fuel cell stack is also provided.

Abstract: A method and system for input/output control in a multiprocessor system having multiprocessors coupled to a system memory via a common wide bus. The common wide bus is subdivided into multiple sub-buses which may be accessed individually or in groups by a selected processor, or individual sub-buses may be accessed by multiple processors simultaneously in response to one or more transfer requests. In response to a transfer request having a data address associated therewith, a particular target device is identified. The data address is then written into an address queue. Thereafter, one or more of the multiple sub-buses are utilized to transfer data to or from a single processor in response to a transfer request from a single processor. In response to a transfer request from multiple processors, one or more of the multiple sub-buses may be utilized separately to simultaneously transfer data to or from multiple processors.

Abstract: A partition system includes a freestanding partition system having a pocket-defining partition, and a pocket door slidably supported on the partition system for movement into and out of the pocket. The door includes a door frame having a bottom section defining a cavity that opens downwardly, and a stiff plate-shaped light seal is operably positioned in the cavity for vertical movement by gravity between different positions as the light seal engages and rides along a floor surface. The door includes an adjustable door frame having a rectangular shape with generally square corners and straight sides, but a trailing stile of the door frame is longitudinally adjustable such that, when adjusted, the rectangular shape changes to an orthogonal shape where at least one of the sides of the door frame is angularly distorted from the rectangular shape. This allows the door frame to be adjusted to better fit a door opening. The door further includes offset wheels that engage interior surfaces in the pocket-defining partition to accurately locate the door in the pocket to prevent damage, despite very low clearance. The door further includes a leading vertical side edge having a non-planar mating surface shaped to mateably dovetail into and engage an abutment surface on a lock jamb of the partition system in a manner that prevents light from leaking between the surfaces when the door is in a closed position.

Abstract: A method of determining the color and profile of a target surface involves scanning the target surface with an incident light beam containing a plurality of component wavelengths, forming a beam of light reflected from the target surface and synchronized with the incident beam; and splitting the reflected beam into separate sub-beams of different wavelengths. The sub-beams are directed onto a sensor array to permit their relative positions to be determined as the incident beam moves over the target surface. A portion of the reflected beam is directed onto a color sensitive photodetector to obtain data representative of the approximate color composition of the reflected beam. The color and profile of the target surface is determined from the relative positions of the sub-beams on said sensor array using the data representative of the approximate wavelength composition to resolve ambiguities in the results. The split portion of the reflected beam can also be sampled at a higher rate than the sensor array to obtain information about the appearance of the surface at a higher resolution than possible with the sensor array alone.
