  • Patent number: 7949453
    Abstract: A method controlling a clutch arrangement that serves, in a powertrain of a motor vehicle, for the transmission of a torque from an input element to an output element. Starting from an activated state of the clutch arrangement, a respective estimated torque value is calculated in repeating calculation cycles. A torque build-up value is calculated in dependence on at least one speed difference value. A torque reduction value is calculated in dependence on at least the last calculated estimated torque value. The estimated torque value is re-calculated on the basis of the last calculated estimated torque value by up integration of the calculated torque build-up value and down integration of the calculated torque reduction value. The recalculated estimated torque value is compared with a torque threshold value. The clutch arrangement is deactivated when the recalculated estimated torque value is below the torque threshold value.

  • Patent number: 7944774
    Abstract: A method for marine seismic surveying includes towing seismic sensors in a plurality of streamers in the water, actuating a seismic energy source in the water at selected times and detecting seismic signals at the sensors resulting from the actuation of the source. A data trace is created for each of the detected signals. At least one Fresnel zone is determined for at least some of the seismic data traces. A contribution of each of the traces to each one of a plurality of bins defined in a predetermined pattern is computed, based on the Fresnel zone associated with each trace. Based on the computed contributions, a maximum lateral distance between corresponding seismic sensors is determined that will result in a contribution sum above a selected threshold.

  • Patent number: 7936640
    Abstract: Methods of processing seismic data to remove unwanted noise from meaningful reflection signals are provided for. Assembled seismic data are transformed from the offset-time domain to the time-slowness domain using a Radon transformation. Preferably, the Radon transformation is applied within defined slowness limits pmin and pmax that will preserve coherent noise, and according to an index j of the slowness set and a sampling variable ?p; wherein j = p ma ? ? x - p m ? ? i ? ? n + 1 ? ?sec ? / ? m ? ? ? p , ?p is from about 0.5 to about 4.0 ?sec/m. The coherent noise content of the transformed data is then enhanced, and the primary reflection signal content diminished by filtering at least a subset of the transformed data.

  • Patent number: 7937202
    Abstract: The computer 26 sends actuating signals to the resistive device 38 to resist the occupant input to the accelerator 22, but only when the vehicle speed exceeds a threshold while the seat belt 24 is not fastened about the occupant 28. This invention is characterized by applying the resistance and adjusting the threshold in proportion to the number of times the seat belt 24 is not fastened while the vehicle speed exceeds the threshold compared with the number of times the vehicle 20 exceeds the threshold speed. Also, the threshold may be adjusted so resistance may be applied at speeds that would normally be acceptable to have the seat belt 24 unfastened when the vehicle 20 is operated at these speeds too often.

    Abstract: A vehicle recognition allowing device is provided which allows the recognition of a traveling state of a vehicle, including a two-wheeled vehicle to be recognized and does not require a sophisticated image processing function. When a change in the speed, traveling state or both of the vehicle is detected by a traveling state detecting part, flickering frequencies of respective infrared ray markers are increased or decreased to a frequency corresponding to the change in speed, traveling state or both. Alternatively, flickering duty ratios of the respective infrared ray markers can be changed to a duty ratio corresponding to the new speed, traveling state or both.

  • Patent number: 7925408
    Abstract: During the standstill state maintenance control executed by an electric parking brake system, the moving force-based target tension Frefb is determined based on the inclination angle of a vehicle and the shift position each time the predetermined program is executed, and the tentative target tension Fref(n) in the current routine is set to a smaller value from among the moving force-based target tension Frefb and the maximum value Fmax. The control target tension Fref(n)* is set to a larger value from among the control target tension (the final target tension) Fref(n?1)* in the immediately preceding routine and the tentative target value Fref(n). Even if the tentative target tension Fref(n) is smaller than the control target tension Fref(n?1)*, the control target value Fref(n)* is not set to a value smaller than the control target tension Fref(n?1)*.

  • Patent number: 7920959
    Abstract: A method and an apparatus is provided for determining the velocity vector, speed, and direction of moving vehicles traveling on roadways which change elevation and have curves. A camera mounted above a roadway observes at least one vehicles traveling in different directions on different roads. Each pixel in the two-dimensional optical image is mapped into a three-dimensional real world location to enable the moving vehicles to be analyzed in the three-dimensional real world as they travel on roads, which may change elevation and may have curves. The estimated vehicle velocities may be displayed on an image near the moving vehicle. Individual images with vehicle velocities may be posted on an Internet site. The sequence of optical images, or streaming video, with the displayed vehicle velocities may also be used for television news programs that show traffic moving on the roadways.
