Abstract: A motor-pump assembly for providing pressure for a motor vehicle brake system actuation device with a pneumatic brake booster, including a pump and an electric motor driving the pump. The pump is a double diaphragm pump with two opposing working diaphragms each clamped between a pump housing and a working chamber cover to delimit a working chamber and which are movable by a crank drive having an eccentric and connecting rods. The connecting rods each have a connecting rod shank and a connecting rod eye and are mounted movably on the eccentrics by roller bearings. To provide a motor-pump assembly which meets requirements relating to acoustic comfort, a resilient decoupling is provided between each connecting rod eye and the roller bearing, which damps transmission of vibrations to the roller bearing in the connecting rod shank which occur on a force direction change on the rotation of the crank drive.

Abstract: A file namespace hierarchy bypass and method to access files are provided. The bypass can be employed, for example, as a computer-readable medium with instructions for generating a unique identifier associated with a file and instructions for accessing the file based on the unique identifier and a specified search space. A computer-readable medium having instructions for obtaining the unique identifier and specified search space associated with the file and instructions for generating a path designation by combining the unique identifier and the specified search space used to access the file may also be employed. The method for bypassing the namespace hierarchy of the file, for example, may include passing the unique identifier and specified search space to a program and accessing the file based on a path designation generated by the program by combining the unique identifier and specified search space.

Abstract: A file stream exchange system and method are provided. The system can be employed, for example, with a storage system that supports transactions as a primary mechanism and employs a rich type system. The system provides a mechanism for the storage system to provide reliable updates to file streams while preserving the common criteria for security. The system employs a unique way of remapping the file-streams associated with the file-backed items that eliminates the need for copying over basic attributes, security information and timestamps etc. Significantly, the system does not rename the files involved in the operation nor does the system rely on attribute tunneling to copy over any subset of attributes for the completion of the task. The system includes a replace stream component which is a kernel mode mechanism that allows transactional exchange of stream data of two file-backed items without violating the common criteria for security.

Abstract: A technique is provided whereby a stream of data located in a first storage location is registered for migration administration and according to preset criteria, portion(s) of the stream of data that are suited to another storage location are migrated to maximize system storage efficiencies. The file system may have use of facilities that enable the monitoring of files/streams that have been registered for migration administration or files/streams may be polled according to preset criteria. If the stream of data has portions to migrate to another storage location, the hierarchical storage management (HSM) system migrates the data to the other storage location, such as to long term or off-line storage, and preserves the data relationships of the stream via metadata. The technique allows for multiple volumes to be spanned by the migration target location, and multiple file systems may service the source and target.

Abstract: A vehicle includes four wheels, a drive axle, a power train which connects a vehicle engine to the drive axle via a transmission, a clutch, and an axle differential, a brake system, which may brake at least the wheels associated with the drive axle independently of the other wheels, a steering system which includes a manual steering device, at which a driver may set a steering angle for steerable wheels, and a control system, which brakes at least the drive axle wheel inside the curve and generates a steering-supporting braking torque on this wheel below a predefined vehicle velocity and as of a predefined steering angle. In order to improve the steering support, the control system monitors the status of the transmission and/or the clutch, the control system actuating the brakes of the appropriate wheel as a function of this status in order to generate the steering-supporting braking torque.
