  • Patent number: 6906550
    Abstract: A terminator circuit for use on a pin of an integrated circuit (IC) is disclosed. A preferred embodiment of the present invention includes a clamp circuit that turns on when the voltage at the pin exceeds a threshold value (either an upper or lower bound). Logic and biasing circuitry are used to allow multiple modes of operation by adjusting the threshold values. A particular mode may be selected at any given time so as to strike an appropriate balance between signal quality and power consumption with respect to a particular terminator or set of terminators. This prevents excessive power consumption due to terminator circuitry at inactive or infrequently active IC pins.

  • Patent number: 6887949
    Abstract: A hydrido-silicone is incompletely reacted with (preferably) a long chain olefin under hydrosilylation conditions to produce a partially substituted hydrido-silicone that is further reacted under hydrosilylation conditions with a vinyl containing MQ resin to partially consume the remaining hydride species which is then reacted under hydrosilylation conditions to consume the remaining hydride species with a long chain di- or multi-alkenyl silicone to produce a composition that is useful as an anti-mist agent in the coating of flexible supports.

  • Publication number: 20050004569
    Abstract: A bipolar electrosurgical instrument having a pair of relatively moveable jaws, each of which includes a tissue contacting surface. The tissue contacting surfaces of the jaws are in face-to-face relation with one another, and adjacent each of the tissue contacting surfaces are first and second spaced-apart electrodes that are adapted for connection to the opposite terminals of a bipolar RF generator so as to generator a current flow between the electrodes. The first and second electrodes of one jaw are in offset opposed relation, respectively, with the first and second electrodes of the other jaw. A cutting portion is provided between the jaws. The cutting portion is moveable to provide the instrument with a scissors-like capability or a grasper-like capability, depending on the position of the cutting portion.

  • Publication number: 20050001520
    Abstract: A display case comprises a first section having a top wall, a bottom wall and a back wall connected between the top and bottom walls, and, a second section having opposed side walls with a front wall connected between them. The second section slides into engagement with the first section to form a closed interior. The bottom wall of the first section is integrally formed with a bracket which includes first and second arms connected in an inverse, L-shape, with one of the arms oriented parallel to and spaced from the bottom wall to form a space within which a shelf is received. A thumb screw or other mounting device extends through the bracket arm to engage the shelf and secure the display case thereto.
