Abstract: A sealing device for sealing a pipeline arrangement, a method for the production of a sealing device, and a pipeline system including a sealing device and a pipeline arrangement. The sealing device includes a seal and data medium assigned to the seal with electronic data memory to which seal specific information can be or is written.

Abstract: A main shaft for a transmission or a countershaft for a transmission shall be constructed in an especially light-weight manner. The transmission of high torques, such as is the case for the main shaft or countershaft for a transmission, is problematic when the base body of the shaft consists of a fiber composite material. A metal element (20, 22) is now laminated into the base body, and a gearwheel (28, 30) can then be connected to this metal element (20, 22) in a force-fit manner, so that high torques can be transmitted.

Abstract: An access control unit to interface one ATM core network and at least one bidirectional access network is provided, which includes means to perform ATM signalling and resource management to provide dynamically adjustable ATM switched virtual connections (SVC) for subscribers connected to the access network. The central access control unit processes ATM signalling and resource management to enable e.g. switched virtual connection over HFC. During the ATM signalling phase the applications negotiate the required resources which the central access control unit of HFC extracts. The central access control unit has the ability to allow or reject a connection (SVC) setup. As soon as the a new SVC is established the access control unit performs on the ATM layer the installation of the negotiated ATM connection values (VPI (virtual path identifier), VCI (virtual channel identifier), . . . ) at the different involved HFC network elements.

Abstract: In a communications system the allocation of available resources is done by means of time frames of variable length. Adaptive reserving of resources is carried out in cycles. Calculation of the current time frame length is based, for example, on the current amount of traffic. In a communications system with low traffic volume short time frames are used for short access delays and short access times. In a communications system with high traffic volume long time frames are used taking into account a predetermined maximum time frame length, in order on the one hand to increase fairness and on the other hand to increase the system performance. A resources allocating or assigning algorithm is used, which carries out dynamic allocation or assignment of resources by suitable choice of time frame lengths. A time slot of a predetermined length, for example, acts as basic unit.
