Abstract: An arrangement for a switching function unit for Ethernet having a number of active components of the Ethernet which are combined by a switching function unit to form a functional unit; and at least three mutually independent power supplies for supplying power to the active components, wherein a first of the at least three power supplies is a local power supply for the switching function unit, a second of the at least three power supplies is a first extraneous power supply via Ethernet for the switching function unit, and a third of the at least three power supplies is a second extraneous power supply via Ethernet for the switching function unit.

Abstract: A secured bearing arrangement for at least one journal of a universal joint, said journal being rotatable about an axis of rotation while being mounted in a housing. The bearing arrangement comprises at least one universal joint housing that is provided with at least one bore which extends in the direction of an axis and has an internal surface as a bearing surface. A bearing bush which has a bearing axis and inside which the journal is mounted so as to be rotatable about its axis or rotation, is mounted on the internal surface within the bore. A securing element allows the bearing bush to be secured within the bore in one axial direction of the bearing axis, said one axial direction facing away from the journal. The securing element is disposed between the mounted bearing bush and the universal joint housing in a radial direction of the bearing axis while being connected to the universal joint housing between the mounted bearing bush and the universal joint housing.

Abstract: To create a connection between different mobile radio systems, data transmission between a first mobile services switching center (2GMSC) of a first mobile radio system (2G) and a second mobile services switching center (3GMSC) of a second mobile radio system (3G) is proposed, whereby the mobile services switching centers are connected through an interface (A*), via which useful data is transmitted at a variable useful data transmission rate, in which the useful data is transmitted within data frameworks including a definite pre-determined number of data fields, whereby, depending on the amount of useful data to be transmitted, at least one part of the data fields is first specified with the useful data and then the remaining part of the data fields is specified with dummy bits. Thus, a transmission channel which uses a fixed gross transmission rate (e.g., 64 kbit/s), but a variable useful data transmission rate (0-57.6 kbit/sec) is created.

Abstract: A retaining system for passengers of an automotive vehicle in which an impact element, which is movable toward the part of the body to be retained in case of a crash, is fixed to the vehicle in front of the passenger of the vehicle and is moved into position to block the space in front of the seat on which the passenger is seated only in a crash situation. This retaining system is intended to prevent the so-called "submerging" effect, by which a passenger slides into the space in front of the seat upon which the passenger is seated in a crash situation. The retaining system includes an impact element which is swingable toward the passenger about an axis which extends transversely to the longitudinal axis of the vehicle. If the interior design of the vehicle requires, the impact element can be arranged to undergo translatory movement in the direction of the passenger in addition to the swinging movement.

Abstract: A bumper system including an extendable bumper resiliently disposed in the direction of impact. The system is compact and, even at elevated impact speeds, protects the automotive vehicle against damage. The bumper is extended by an adequate amount before or during the situation of danger. A progressive damping characteristic and a suitable drive to quickly extend and to safely return the bumper are provided.

Abstract: An occupant safety device for automotive vehicles is proposed which saves mounting space and which is comprised of a roll bar (2, 33, 34) allowing both to be brought into its extended final operative position by a signal being generated in the event of severe impact by means of elastic prestressing means (13, 27) and to be adjusted into the extended final operative position or into the final lowered position by means of an additional drive (5, 6, 7, 8, 9, 17, 18), the movement of the roll bar (2, 33, 34) taking place substantially in a plane which runs at right angles relative to the longitudinal axis of the vehicle, and that at least one headrest (15) is provided at the roll bar (2, 33, 34).

Abstract: A lift-up sun roof, in particular for automotive vehicles, featuring a simple design and a low overall height is proposed, with a rigid cover (2) which in its closed position closes a roof opening in a roof area (1) and which is guided at lateral guide rails (5, 6) by means of siding elements (4) and is raisable with one end above the stationary roof area (1) or, at option, slidable below the said roof area (1) upon lowering of one end. In this configuration, the connection between said cover (2) and said sliding element (4) is envisaged to be effected through a lever (7, 15, 16) which is pivotable about the longitudinal axis of said guide rail (5, 6), the angle of pivoting being determined by a control ramp (9).
