Patent number: 8049605Abstract: 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.Type: GrantFiled: January 21, 2011Date of Patent: November 1, 2011Assignee: PACCAR IncInventors: Martin Jay Caspe-Detzer, Andrew Joseph Ressa, Phu Vi Tran, Ian David O'Connor, John William Espinosa, Paul Stephen Crowe

Patent number: 7507522Abstract: 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.Type: GrantFiled: May 17, 2005Date of Patent: March 24, 2009Assignee: E.

Publication number: 20080306636Abstract: 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.Type: ApplicationFiled: June 6, 2007Publication date: December 11, 2008Applicant: PACCAR INCInventors: Martin Jay Caspe-Detzer, Andrew Joseph Ressa, Phu Vi Tran, Ian David O'Connor, John William Espinosa, Paul Stephen Crowe

Publication number: 20060106725Abstract: 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.Type: ApplicationFiled: November 12, 2004Publication date: May 18, 2006Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Paul Finley, Daniel Nguyen, Kim-Khanh Tran, Vi Tran

Patent number: 7039147Abstract: 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.Type: GrantFiled: February 14, 2003Date of Patent: May 2, 2006Assignee: Rambus Inc.Inventors: Kevin S.
