Abstract: Fluid treatment elements substantially inhibit electrical charge imbalances and/or build-ups of electrical charges. A fluid treatment element may comprise a multilayer composite including an electrically conductive fibrous matrix, having an upstream side and a downstream side, disposed on a porous substrate, also having an upstream side and a downstream side, which supports the fibrous matrix. The fibrous matrix may include a combination of conductive and nonconductive fibers, wherein the conductive fibers include metal fibers and substantially inhibit an electrical charge and/or build-up of electrical charge. The conductive metal fibers of the electrically conductive fibrous matrix may comprise less than about 50% by weight of the conductive and nonconductive fibers and may have diameters in the range from about 1 ?m or less to about 10 ?m.

Abstract: A fluid treatment element for treating a fluid flowing through the element comprises a first conductive layer and a second conductive layer electrically connected to the first conductive layer. The element further comprises a nonconductive porous treatment medium between the first and second conductive layers. The first and second conductive layers are positioned to offset electrical imbalances caused by fluid flowing through the nonconductive porous treatment medium.

Abstract: The present invention provides methods and fluorescent compounds that facilitate detecting and labeling of a fusion protein by being capable of selectively binding to an affinity tag. The fluorescent compounds have the general formula A(B)n, wherein A is a fluorophore, B is a binding domain that is a charged chemical moiety, a protein or fragment thereof and n is an integer from 1-6 with the proviso that the protein or fragment thereof not be an antibody or generated from an antibody. The present invention provides specific fluorescent compounds and methods used to detect and label fusion proteins that contain a poly-histidine affinity tag. These compounds have the general formula A(L)m(B)n wherein A is a fluorophore, L is a linker, B is an acetic acid binding domain, m is an integer from 1 to 4 and n is an integer from 1 to 6.

Abstract: A card guide is used in guiding a circuit board with respect to a chassis. The card guide includes a guide rail extending along the card guide in a first direction, an end portion configured for removably attaching the card guide to the chassis, and a finger extending in a second direction. The finger has a shape and size to allow interconnection with an adjacent card guide. The finger defines an endpoint of a space allowing airflow in a third direction past the card guide.

Abstract: An apparatus and method for mincing a gel includes a gel mincing tube and a mesh material. The mesh material extends across the end of the tube. To subdivide a gel using the mincing apparatus, a gel is placed upon the mesh material in the mincing tube, the mincing tube, mesh material and the gel are spun in a centrifuge, forcing the gel through the mesh material so that the gel is subdivided into generally uniform smaller fragments. The mesh material may be secured to a tube in the form of a nesting tube. The nesting tube nests within the opening of a recovery vessel. The mesh material may be placed in series with a conditionally porous membrane in the nesting tube. Centrifuging the nesting tube and the recovery vessel subdivides gel material into fragments by forcing the gel through the mesh material. The gel subsequently falls upon the membrane, and may be treated on the membrane to extract or otherwise treat analytes in the gel material.

Abstract: What is disclosed is a computer-implemented method for generating a right transfer instruction regarding a transferable right in a priced item. The process includes the steps of graphically presenting a chart of a price of the priced item versus time; and setting a trigger control overlaid on the chart that is responsive to the price to initiate the right transfer instruction when the price reaches a predetermined relationship to a particular price for the priced item.

Abstract: A method and system for analyzing power distribution in an integrated circuit chip includes dividing a clock cycle of the integrated circuit chip into a plurality of time periods, dividing the integrated circuit chip into a plurality of cells, performing a static timing analysis for the plurality of cells to obtain current waveform data for each cell and each time period, and performing a power distribution analysis using the current waveform data.

Abstract: Synchronous timing techniques provide redundant reference frequencies to enable a packet switching system to continuously generate one or more master clock frequencies when an original reference frequency is lost or unavailable.

Abstract: An integrated circuit includes a CPU, a power management unit and plural functional units each dedicated to executing different functions. The power management unit controls the threshold voltage of the different functional units to optimize power/performance operation of the circuit and intelligent power management control responds to the instruction stream and decodes each instruction in turn. This information identifies which of the functional units are required for the particular instruction and by comparing that information to power status, the intelligent power control determines whether the functional units required to execute the command are at the optimum power level. If they are, the command is allowed to proceed, otherwise the intelligent power control either stalls the instruction sequence or modifies process speed.
