  • Systems and methods of automatic navigation on the world wide web
    Patent number: 7529808
    Abstract: Disclosed are systems and methods of automatic navigation on the world wide web. A server receives an anonymous signal from a browser, and selectively determines a resource identifier corresponding to one of the plurality of Internet domains, by accessing data structures that are stored apart from the browser. The server generates a signal corresponding to the resource identifier, and sends the signal, to allow the browser to access a signal associated with the resource identifier.

  • Driveline shift quality in variable valve engine equipped drivelines
    Patent number: 7462129
    Abstract: In one example, a method for controlling powertrain operation in a vehicle is provided, the powertrain having an engine and an automatic transmission, the engine having at least an electrically actuated cylinder valve. The method includes changing gears from a first discreet gear ratio to a second discreet gear ratio of the transmission; and increasing engine torque during a torque phase of said gear change by changing operation of the electrically actuated cylinder valve, and decreasing engine torque during an inertia phase of said gear change.

  • System and method for reducing vehicle acceleration during engine transitions
    Patent number: 7426915
    Abstract: A method for controlling an engine to reduce vehicle shuffle mode vibration during mode transition. The engine includes multiple cylinders, each with at least one electrically actuated valve, and the engine operates in a first mode having a first number of firing cylinders and a second mode having a second number of firing cylinders. The method comprises transitioning the engine from operating in the first mode to the second mode; adjusting at least a valve timing or lift of one of a last cylinder to be fired in said first mode and a first cylinder to be fired in said second mode to temporarily adjust a cylinder torque and thereby reduce vehicle shuffle mode vibration.
