Abstract: Hydrosilylatable compositions employ ruthenium compounds with a ligand sphere comprising at least two independent carbon ?-bonded ligands, at least one of these ligands being selected from the group consisting of ?6-bonded arene ligands, ?6-bonded triene ligands, ?4-bonded 1,5-cyclooctadiene ligands and ?4-bonded 1,3,5-cyclooctatriene ligands as a hydrosilylation catalyst.

Abstract: Organosilanes are prepared efficiently by hydrosilylation of an alkene in the presence of iridium compounds as catalysts and an inorganic, metal organic, or organic oxidant as cocatalyst. side reactions and catalyst deactivation are thereby minimized.

Abstract: A data-processing system having at least one operating memory holding operating data is provided with a protection unit having an execution environment protected from unauthorized access. At least one monitoring logic in the execution environment is connected to the operating memory for monitoring unauthorized modifications, access, or similar protection violations of the operating data stored in the operating memory and for generating an output on detection of such a protection violation. A protection logic in the execution environment holds replacement data capable of replacing the operating data and is connected to the monitoring logic for, on generation of the output, providing to the operating memory the replacement data for the operation or for a substitute operation of the data-processing system.

Abstract: A vehicle having electrical or electronic components connected to a communication network also has a security unit connected to the network. This security unit in turn has at least one cryptography module connected to the communication network and with which cryptographic codes are generated, stored, managed or processed and at least one coordination module for the coordination of individual modules within the security unit.

Abstract: A method for authenticating a software package, which is provided by a software supplier and which contains a software component that can be loaded into a terminal. The software component is provided with a first authentication suffix, which is verified in order to carry out an authenticity test in the terminal. A higher-level authenticating site is provided, performing authenticating measures on the software package to increase security, wherein the measures performed by the higher-level authenticating site include providing the software package with at least one second authentication suffix instead of the first authentication suffix after successful checking of the software package provided by the software provider and including the first authentication suffix in addition to the software component of the software package.

Abstract: The invention relates to a vehicle seat comprising at least one gas spring (9) which damps vibration and adjusts the seat height, said gas spring being arranged between a seat frame (1) and a base frame (2), and comprising a valve arrangement (43, 44) for adjusting the pressure in the gas spring (9) and a compressor (45) assigned to the vehicle seat (17, 20, 23), said compressor having a drive motor for feeding compressed gas to the gas spring (9), wherein a belt roller device comprising a belt (11) rolled around an axle (12) is arranged between the seat frame (1) and the base frame (2), the first end (11a) of said belt being attached to a belt roller mechanism (10) arranged on the seat frame (1) and the second end (11b) of said belt being attached to the base frame (2), and a detector (16) which detects a belt rolling movement is attached to the seat frame (1).
