Patent number: 7486040Abstract: A motor control circuit for supplying power to a DC motor which drives a mechanism having a driven shaft, the control circuit having a parallel combination of a capacitor and switch in series with the DC motor. When the movement of the driven shaft is obstructed, the motor driver and the switch are synchronized in a manner to first charge the capacitor and then to reverse the voltage generated by the motor driver to momentarily double the voltage applied to the DC motor so that the increased torque of the DC motor is able to overcome the obstruction. The mechanism having a shaft driven by the DC motor may be, for example, an ETC valve or a window regulator.Type: GrantFiled: August 22, 2006Date of Patent: February 3, 2009Assignee: Delphi Technologies, Inc.Inventor: Charles R.

Patent number: 7486005Abstract: An electrical connector arrangement for a piezoelectric actuator (10) having a stack (26) of one or more piezoelectric elements, the electrical connector arrangement including positive and negative terminals (30, 32) for connection with distribution electrodes (44a, 44b) of the piezoelectric stack (26). Each of the positive and negative terminals (30, 32) has a lower end face (30d, 32d) which locates adjacent to an upper end face of the stack (26), in use, and a radially outer contact face (30e, 32e) for contact with the distribution electrodes (44a, 44b). The terminals (30, 32) also connect with an external voltage supply, in use. A block (30c, 32c) of each terminal (30, 32) defines the radially outer contact face (30e, 32e) for the stack distribution electrodes (44a, 44b) and thus provides a robust terminal structure.Type: GrantFiled: May 11, 2005Date of Patent: February 3, 2009Assignee: Delphi Technologies, Inc.Inventor: Manfred Kolkman

Patent number: 7486835Abstract: A system and method for enhancing the contrast within an image. An enhanced image can be generated in a real-time or substantially real-time manner from an initial image. The pixel values of the initial image can be used to populate a histogram or otherwise serve as the basis for subsequent processing. A valley can be identified within the range of pixel values for use as a stretch metric used by a stretch heuristic to expand the contrast of the pixel values in the initial image by expanding the range of pixel values associated with the pixels in the histogram. In some embodiments, the initial image is first divided into image regions that are each associated with individualized processing. A bilinear interpolation step can then be performed to smooth the integrated image after the individualized processing is used to stretch the pixels within the individual image regions.Type: GrantFiled: March 17, 2005Date of Patent: February 3, 2009Assignee: Delphi Technologies, Inc.Inventors: Yan Zhang, Ronald M.
