Publication number: 20130042079Abstract: A method for processing data of a control unit in a data communication device, which has a first memory area and a second memory area, and is connected to the control unit through an interface. Data from the control unit is transmitted to the data communication device through the interface. A value is stored identically in the first memory area and in the second memory area. The data communication device tests whether a first trigger is present, and if present, storage in the first memory area is discontinued, or the trigger class of the first trigger is tested and storage in the first memory area is discontinued only in the presence of a predefined trigger class. Subsequently, values of the data are read out from the first memory area, whereby values arriving chronologically after the first trigger are stored in the second memory area by the data communication device.Type: ApplicationFiled: August 9, 2012Publication date: February 14, 2013Inventors: Marc Dressler, Bastian Kellers, Daniel Hofmann, Thorsten Hufnagel

Publication number: 20050242525Abstract: An inventive hot gas seal for sealing an opening, e.g. a gap or hole, in a heat shield element or between heat shield elements of a heat shield or a liner comprises at least one resilient portion for providing a force which is designed such that the hot gas seal can be held in said opening by said force and/or that the sealing efficiency of the hot gas seal is increased by said force. Thus, further means for holding the seal in place and/or for increasing the sealing efficiency are not necessary. The invention is particularly useful if the design of said resilient portion is such that the force provides a holding action and increases the sealing efficiency, at the same time.Type: ApplicationFiled: April 30, 2004Publication date: November 3, 2005Inventors: Stefan Dahlke, Jesse Eng, John Glessner, Daniel Hofmann, Roland Liebe, Kenneth Tamaddoni-Jahromi
