  • Correcting for ambient light in an optical touch-sensitive device
    Patent number: 8004502
    Abstract: The correction of an image for ambient light in an optical touch-sensitive device is disclosed. For example, one disclosed embodiment comprises integrating a first field of pixels in an image data frame for a different duration of ambient light exposure than a second field of pixels in the image data frame.

  • Method for producing attached parts for a vehicle and the thus produced attached parts
    Patent number: 8001688
    Abstract: A method for producing attached parts for a motor vehicle, for example doors, dampers, mudguards formed by internal (1) and external (2) sheets. The external sheet (2) is inward bent in the visible areas of the door or attached part, the sheet edges being practically parallel to the plane of attached parts in the invisible (not apparently visible) areas of the door or attached part. The internal sheet (1) is pushed against the external sheet (2) in a flanged area in such a way that a small accurately defined gap for laser welding is produced. The internal (1) and external (2) sheets are welded to each other in the form of an overlap joint in the opposite invisible areas, thereby compensating tolerances.

  • Multi-stroke internal combustion engine
    Patent number: 7997237
    Abstract: An example engine method utilizes a first intake valve actuated by a first camshaft once every four piston strokes and a second intake valve actuated by a second camshaft once every four piston strokes, but out of phase with the first intake valve actuation, to provide two-stroke operation. Transitions between two and four stroke operation are provided by deactivation and activation of the second intake valve. In this way, the engine may be selectively operated in a two stroke cycle or a four stroke cycle by activating or deactivating one of the intake valves while another of the intake valves continues to operate.

  • Analog-digital conversion circuit, timing signal generating circuit, and control device
    Patent number: 7999716
    Abstract: There are provided an analog-digital converter circuit capable of performing the same degree of operation as being performed at a high-frequency oscillation pulse using a low-frequency oscillation pulse without using the high-frequency oscillation pulse, a timing signal generating circuit generating a timing signal at the high frequency, and a control device using the circuits. In an analog-digital converter circuit, a periodic signal generating circuit allows the first to j-th pulse counting devices of the N pulse counting devices to count a count value X and allows the other pulse counting devices to count a count value X?1 in each sampling period by sequentially generating N serial periodic signals at a delay time interval of [approximate value of one period (T) of periodic signals]÷N. A digital signal generating circuit converts the analog signal to the digital signal.

  • System and method for reducing NOemissions during transient conditions in a diesel fueled vehicle with EGR
    Patent number: RE42609
    Abstract: The present invention is a dual-stage fuel injection strategy for compression ignition engines in which 15-40% of the fuel is injected into the combustion chamber no later than about ?20 to ?30 CA ATDC and as early as IVC. The remaining fuel is then injected in one or more fuel pulses, none of which start before about ?20 to ?30 CA ATDC. The fuel injected early in the compression stroke forms a lean mixture that burns with low soot and low NOx emissions. The combustion of that fuel serves to increase in-cylinder temperature such that the ignition delay of subsequent fuel injection pulses is short. This mode is utilized when it is predicted that a NOx spike is imminent. Various other alternative methods for reducing NOx spikes are also disclosed such as specialized EGR systems that can provide EGR with low manifold vacuum.
