Abstract: The present disclosure relates to a method for detecting unauthorized data traffic in a packet-oriented data network of a motor vehicle, wherein at least one data packet is read out of the data network by a processor circuit, and header data of each data packet is checked for link information indicating that the data packet belongs to a communication link that is permitted for the operation of the motor vehicle. If the data packet is recognized as belonging to a permitted communication link, payload data of the data packet is checked to determine whether data values of the payload data have a value profile that is provided for the communication link. If a permitted communication link or a permitted value profile for the data packet is missing, a detection signal is generated to identify the data packet as unauthorized data traffic.

Abstract: Device for extracting condensates, inside the internal cavity of a cylinder, including a partition disposed in front of an end of the internal cavity. An orifice is positioned between the internal cylindrical wall and the periphery of the partition enabling condensates to pass and to be atomized behind the partition where they are evacuated at the shaft of the cylinder. The cross-section of the opening, between the partition and the cylinder, is a function of the diameter of the cylinder. In cylinders of large diameter, the peripheral rim of the partition may be composed of serrations which, at the same time, also serve to center the partition in the cylinder.
