Abstract: A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized.

Abstract: An image processing system for a motor vehicle, includes a camera system, an image processing module having a data interface for receiving image data produced by the camera system, a memory unit for storing an image processing program, an image processor unit for processing the image data, a display unit for displaying the processed image data, and a miniature computer. At least one of the image processor unit and the display unit are disposed in the miniature computer.

Abstract: The invention comprises a set of two composite masonry blocks, a wall block and an anchor block to construct retaining walls. The wall block is generally trapezoidal in shape and has: a decorative front face opposite and generally parallel to a rear face which defines a key way. The wall block has a top surface which is opposite and generally parallel to a bottom surface. The wall block has side faces which are not parallel so that the width of the rear face is shorter than the width of the front face. An alignment and locking ledge projects downward from the bottom surface and extends across the rear face. The anchor block comprises a first end plate which is opposite and generally parallel to a second end plate. Two parallel side plates extend between and are perpendicular to the first and second end plates. The side plates and the first and second end plates define a central passage.
