  • Patent number: 8101709
    Abstract: The present invention involves synthesizing conducting polymer nanofibers by mixing an oxidant solution with a monomer solution, which includes a monomer and an oligomer of the monomer that is used as an initiator. The oxidant solution includes an oxidizing agent, or oxidant, such as ferric chloride to oxidize the monomer, the oligomer, or both, and begin polymerization. By including an initiator in the form of the oligomer, which may have a lower oxidation potential than the monomer, the rate of polymerization is accelerated, resulting in the nanofibrous morphology. Therefore, the conducting polymer nanofibers may be synthesized without the use of surfactants, hard templates, or seeds, resulting in a simplified and accelerated polymerization process, which enhances homogenous nucleation of the conducting polymer nanofibers.

  • Patent number: 8097799
    Abstract: This invention relates to providing a plectrum holder device that may be easily attached to a guitar at the desired location of the guitar player. More particularly, this invention relates to providing a system for retaining multiple plectrums close to the surface of a guitar, in a low profile configuration, in a convenient location for easy access by the guitar player. Also, a guitar comprising the plectrum holder may still fit in its guitar case due to the low profile of the plectrum holder. Further, the plectrum holder holds picks of a variety of shapes and sizes.

  • Publication number: 20110214024
    Abstract: A technique for collecting and correlating locking data collects and correlates information on a plurality of programs waiting on or holding a plurality of resources in a multi-computer database system. The technique identifies a program executing on one computer of the multi-computer database system that is waiting on a resource. The technique also identifies a second program, executing on another computer, as the ultimate holder of the resource. An operator display screen displays information corresponding to the first program and the second program. The operator display screen may be switched between a multiline display format and a single line display format. The collection, identification, and display of the locking data is performed periodically, to allow the operator to discover locking problems and take a desired corrective action.

  • Publication number: 20110113401
    Abstract: A method of generating a circuit design comprising a T-coil network includes determining inductance for inductors and a parasitic bridge capacitance of the T-coil network. The parasitic bridge capacitance is compared with a load capacitance metric that depends upon parasitic capacitance of a load coupled to an output of the T-coil network. An amount of electrostatic discharge (ESD) protection of the circuit design that is coupled to the output of the T-coil network and/or a parameter of the inductors of the T-coil network is selectively adjusted according to the comparison. The circuit design, which can specify inductance of the inductors, the amount of ESD protection, and/or the width of windings of the inductors, is outputted.
