  • Patent number: 7649416
    Abstract: Sharing one or more load inductors comprises receiving a first input signal at a first terminal of a first amplifier and amplifying the first input signal using the first amplifier. The first amplifier is coupled to one or more load inductors at a second terminal of the first amplifier and is coupled to one or more dedicated source inductors at a third terminal of the first amplifier. Also, a second input signal is received at a first terminal of a second amplifier amplifying the second input signal using the second amplifier. The second amplifier is coupled to the one or more load inductors at a second terminal of the second amplifier and is coupled to one or more dedicated source inductors at a third terminal of the second amplifier.

  • Patent number: 6796146
    Abstract: A method and apparatus for manufacturing patterned glass sheets. In certain embodiments, the resulting glass sheets have a pattern defined therein which is designed so as to simulate conventional glue chipped glass sheets or antique glass. A heated glass ribbon exits a furnace or melter and proceeds through a nip defined between opposing rollers. Pressure on one or both of the rollers in the direction of the nip, combined with a glue chipped simulating pattern or antique pattern defined in an exterior surface of at least one of the rollers, causes the pattern to be transferred from the roller(s) into/onto a surface(s) of the hot glass ribbon. After being patterned, the glass ribbon is annealed and cut into a plurality of different sheets.

  • Patent number: 6237056
    Abstract: A high speed board-to-board data transfer system capable of data transfer over single ended ribbon cable between a slave device and a master device. A slave device comprises a plurality of drivers generating clock signals at above 40 MHz connected to cable connector pins by a trace line through a series termination resistor. A master device comprises a plurality of receivers corresponding to the drivers connected to cable connector pins through a trace line. The ribbon cable is a single-ended ribbon cable using a ground-signal-ground configuration. The drivers, trace lines, resistors, cables, and receivers are chosen to provide reliable data transfer above 40 MHz, preferably between 40 MHz and 80 MHz. Preferred master and slave devices comprise VESA VIP 2.0 masters and slaves transmitting high quality video.

  • Patent number: 5177194
    Abstract: A multi-step process for purifying an immune serum globulin fraction from a crude plasma protein fraction involves precipitating non-serum globulin proteins from an aqueous suspension of the crude plasma protein fraction using a protein precipitant, adding a virus-inactivating agent to the clarified immune serum globulin-containing liquid, absorbing the immune serum globulins onto a cation exchange resin and washing non-serum globulin contaminants from the resin, subjecting the eluate to ultrafiltration to concentrate the immune serum globulins and separate them from low molecular weight species, contacting the concentrate with an anion exchange resin to absorb non-serum globulin contaminants, passing the imune-serum globulins through the anion exchange resin under conditions that leave non-serum globulin contaminants bound to the resin, and subjecting the filtrate to a molecular washing step to produce a purified immune serum globulin fraction.

  • Patent number: 3991450
    Abstract: A method of separating apertured shadow mask flats after annealing in which a stack of thin flats is passed through a roller leveler, with the rollers set apart by a dimension slightly less than the thickness of the stack.
