Patent number: 10282320Abstract: An electronic memory arrangement having at least three memory areas, a memory control unit, and a writing memory-accessing unit configured to carry out write access. A reading memory-accessing unit is configured to carry out read accesses. The memory control unit determines read and write access to the at least three memory areas, and the memory control unit is configured such that after the writing of a first data packet to one of the three memory areas, a following second data packet to be written is written to one on the three memory area to which read access does not place simultaneously during the write access of the second data packet.Type: GrantFiled: July 22, 2011Date of Patent: May 7, 2019Assignee: CONTINENTAL TEVES AG & CO.

Patent number: 8718894Abstract: A communication system having at least one first and a second communication unit. The first communication unit has a counter memory unit which stores a counter value, and is designed such that the occurrence of a first communication event prompts the counter value in the counter memory unit to be changed in a defined first manner. At least the occurrence of a defined reference event is followed by the counter value in the counter memory unit being changed in a defined second manner. In the course of a second defined communication event, the first communication unit transmits the current counter value in the counter memory unit to the second communication unit.Type: GrantFiled: February 3, 2010Date of Patent: May 6, 2014Assignee: Continental Teves AG & Co. oHGInventors: Jörn Schriefer, Jürgen Scherschmidt, Thomas Peichl

Publication number: 20110183529Abstract: An electric connector with a tolerance compensator, includes a plug-in part and a counter part. An electric connection is established when the plug-in part including at least one electrically conductive pin is plugged into the counter part in the z-direction of a Cartesian coordinate system. The counter part has volume elastic properties, is electrically conductive and forms a predetermined volume. The counter part is limited in the z-direction by, respectively, one contact surface. In order to establish an electric connection, the at least one electrically conductive pin is aligned essentially in the counterpart in the z-direction and traverses a contact surface in an essentially perpendicular manner. The volume area of the counter part is calculated such that the pin reaches the volume allowing a reliable electric connected to be established, in the framework of a permitted path tolerance in the x- and/or y-direction when plugging together.Type: ApplicationFiled: May 13, 2009Publication date: July 28, 2011Applicant: Continental Teves AG & Co. oHGInventors: Andreas Heise, Wolfgang Käfer, Jürgen Scherschmidt, Jörn Schriefer
