  • Patent number: 7135884
    Abstract: An integrated device includes a voltage mode transmit driver for matching an output impedance to an output transmission line based on a binary code, an input termination module configured for matching an input impedance to an input transmission line based on an input impedance calibration value using thermometer-based decoding. The voltage mode transmit driver includes, for each differential output signal, a resistor network circuit having pull-up circuits and pull-down circuits for changing the voltage on the differential output signal, and having binary weighted resistance values relative to each other. The input termination module includes pull-up circuits and pull-down circuits having inverse hyperbolic resistance values relative to each other, and using thermometer-based decoding to ensure a linear change in input impedance during transitions in the input impedance calibration value.

  • Publication number: 20030152726
    Abstract: Polyester containers having a reduced coefficient of friction (“COF”) are produced by increasing the surface roughness of the polyester using either thermal crystallization or solvent crystallization. Because the low COF reduces or eliminates friction between polyester containers, the containers do not become entangled and disrupt the manufacturing process. As a result, the containers move easily through typical conveying and filling lines in manufacturing processes that use the containers.
