  • Publication number: 20160225925
    Abstract: A conductive paste composition comprises (i) an inorganic powder comprising at least a conductive powder, (ii) at least one microgel polymer, and (iii) a solvent. The paste composition may be used in a process for manufacturing an electrical device comprising: preparing a substrate; applying the conductive paste onto the substrate in a preselected pattern; and heating the applied conductive paste to form a conductive structure that provides an electrode for connecting the device. The paste composition beneficially permits the formation of narrow, high aspect ratio features in the conductive structure.

  • Patent number: 8049605
    Abstract: Aspects of the present invention are directed at allowing a vehicle to idle for a predetermined amount of time before shutdown. In accordance with one embodiment, a method is provided that accepts input from the vehicle operator to initiate a countdown to vehicle shutdown. When the input is received, a countdown is initiated that is regularly updated to reflect the passage of time. During the countdown, a vehicle ignition bus is maintained in an active state and a countdown value that reflects the time remaining before shutdown is presented on a graphical display. Then, in response to expiration of the countdown, the method allows the vehicle ignition bus to transition into an inactive state.

  • Publication number: 20090299113
    Abstract: A method for purifying liquid alkanes, especially dicyclic alkanes, for use in immersion lithography is provided. The method produces alkanes having absorbance at 193 nm of ?0.1/cm, and residue of ?100 ppm. The liquid alkane compositions are useful as immersion liquids in photomicrolithography employed for production of electronic circuits.

  • Patent number: 7507522
    Abstract: The present invention relates to novel unsaturated polycyclic compounds containing two fluoroalcohol substitutents. This invention also relates to homopolymers and copolymers derived from such unsaturated polycyclic compounds. The copolymers are useful for photoimaging compositions and, in particular, photoresist compositions (positive-working and/or negative-working) for imaging in the production of semiconductor devices. The polymers are especially useful in photoresist compositions having high UV transparency (particularly at short wavelengths, e.g., 157 nm) which are useful as base resins in resists and potentially in many other applications.

  • Publication number: 20080306636
    Abstract: Aspects of the present invention are directed at an enhanced display for presenting tachometer information. In accordance with one embodiment, a method is provided that causes an electronic control unit associated with a dashboard display to present the current engine speed (e.g. RPM) relative to an optimal range in which fuel efficiency is maximized. More specifically, the method includes obtaining a set of tachometer data at the electronic control unit that defines the lower and upper limits of the optimal range in which fuel efficiency is maximized. Periodically, the current engine speed may be obtained by the electronic control unit associated with the dashboard display. Then, the method causes the current engine speed to be presented on the graphical display relative to the lower and upper limits of the optimal range.

  • Publication number: 20060106725
    Abstract: A software program on the computer system is represented by an icon, which is displayed to a user within one of several available icon-level graphical user interfaces (GUIs) of the operating system (OS). In addition to the standard icon displayed in the icon-level GUI, a license status symbol is associated/affiliated with the icon. The license status symbol indicates the license status of the particular application, from among shareware, un-licensed, valid license, expired license, expiring license, time to license expiration, and/or evaluation license. Each different license status is represented by a unique/identifiable license status symbol, and each application existing in one of these license status on the computer system are represented by its icon and associated/affiliated license status symbol. By viewing the icon and associated/affiliates license status symbol, a user is able to identify the specific license state of the application without having to open/run the application.

  • Patent number: 7039147
    Abstract: Delay locked loop circuitry for generating a predetermined phase relationship between a pair of clocks. A first delay-locked loop includes a delay elements arranged in a chain, the chain receiving an input clock and generating, from each delay element, a set of phase vectors, each shifted a unit delay from the adjacent vector. The first delay-locked loop adjusts the unit delays in the delay chain using a delay adjustment signal so that the phase vectors span a predetermined phase shift of the input clock. A second delay-locked loop selects, from the first delay-locked loop, a pair of phase vectors which brackets the phase of an input clock. A phase interpolator receives the selected pair of vectors and generates an output clock and a delayed output clock, the amount of the delay being controlled by the delay adjustment signal of the first delay-locked loop circuitry.

  • Publication number: 20060019609
    Abstract: A method, apparatus, and computer instructions for a communications device transferring data. A signal strength is received for a communications link used to transfer data to a destination. In response to the signal strength less than a threshold, the data is cached in the communications device to form cached data. In response to a loss and reestablishment of the communications link, the cached data is sent to the destination.
