Title: Cell stack system block
Inventor: BACKSTROM ANDREAS KARL
IPC: H01M8/02
Filed: 2010-07-14
Abstract: A system block (10) for mounting one or more cell stacks consists of two opposed half-blocks (12, 14) between which is sandwiched at least one separation plate (16). Each half-block (12, 14) comprises a flat plate and a multiplicity of protruding ribs. The ribs may be formed by injection moulding. The protruding ribs on an inner surface, that is a surface that faces the separation plate, define flow channels for fluids, while protruding ribs (20) on an opposite, outer surface of a half-block (12) define locating recesses or sockets for connection to cell stacks or to fluid flow ducts. At least some of the flow channels communicate with apertures in the flat plate of the half-block or apertures in the separation plate (16), and the cell stacks communicate with some of these apertures. The system block (10) enables fluids such as liquid electrolyte, hydrogen and air, to be supplied to and removed from one or more fuel cell stacks, while only requiring a single external connection for each fluid to or from the system block.

Title: Method and arrangement for short coherence holography
Inventor: KORNER KLAUS
IPC: G01B9/021
Filed: 2011-12-23
Abstract: The invention relates to a method and arrangement for short coherence holography for distance measurement, for profile detection and/or for 3D detection of one or more object elements and/or object areas and/or objects or for readout of holographic volume memories with a holographic interferometer and with at least one short coherence light source. For each optically detected object element in the hologram the holographic interferometer has an optical path difference clearly unequal to zero. For optical detection of the object in the form of holograms at least one spectrally integrally detecting, rastered detector is arranged. According to the invention the short coherence light source with frequency comb is designed with the optical delay length Y1. Detected holograms are digitally reconstructed. Relative distances of object elements with respect to one another or also absolute distances relative to a reference in the arrangement for holographic interferometry are digitally calculated from the hologram reconstructions, so that finally a 3D point cloud of object elements and/or object areas and/or objects is produced. Using the approach according to the invention it is also possible for data to be read out optically in parallelised form from holographic volume memories or three-dimensionally structured signatures.

Filed: 2015-09-28
Abstract: A graphics processing pipeline comprises a tessellation stage 10 to tessellate a patch representing an object to be rendered, so as to generate positions for a set of vertices for one or more output primitives. The pipeline also includes a primitive assembly stage 20 to assemble one or more output primitives for processing using (1) the positions for a set of vertices generated by the tessellation stage and (2) pre-defined information defining the connectivity between at least some of the vertices of the set of vertices. As such, the tessellation stage need not define the connectivity between the vertices, and may only calculate some connectivity information, or none at all. The tessellation stage may only calculate connectivity information between the vertices of the outer primitives, and not those of the inner primitives, which may be provided by the pre-defined information. The pre-defined information may comprise one or more lists of vertices, each list listing vertices in an order in which the vertices should be joined up to produce output primitives.
