  • Patent number: 8695989
    Abstract: 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.

  • Publication number: 20130041550
    Abstract: A method is provided for processing data in an influencing device, whereby the influencing device is connected to a vehicle control unit and to a data processing unit. The vehicle control unit and the influencing device are disposed in a motor vehicle or, for example, on a test bench in a laboratory. A first program runs in the vehicle control unit. Data are exchanged according to an XCP protocol and/or a CCP protocol between the data processing unit and the influencing device. The influencing device has a second execution unit, which executes predetermined data processing steps more rapidly than the first execution unit. The data exchanged by the XCP protocol or the CCP protocol are checked for a predetermined criterion and, based on the result of the check, the data are processed either in the first execution unit or in the second execution unit.

  • Publication number: 20130042079
    Abstract: 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.

  • Publication number: 20040038194
    Abstract: A method simultaneously detects and captures double-stranded DNA sequence. The method includes providing a sample. The next step is adding a forward primer for the double-stranded DNA sequence and a reverse primer for the double-stranded DNA sequence; either the forward primer or the reverse primer have a capture agent, the other has a detection agent. The next step is replicating the double-stranded DNA sequence. The next step is binding the capture agent to a capture medium. The next step is rinsing the sample. The next step is detecting the detection agent. The method also can be applied to double-stranded DNA that has been reverse-trasncripted from single-stranded RNA.
