Abstract: A data processing device is described with a memory and a first and a second data processing component. The first data processing component comprises a control memory comprising, for each memory region of a plurality of memory regions of the memory, an indication whether a data access to the memory region may be carried out by the first data processing component and a data access circuit configured to carry out a data access to a memory region of the plurality of memory regions if a data access to the memory region may be carried out by the first data processing component; and a setting circuit configured to set the indication for a memory region to indicate that a data access to the memory region may not be carried out by the first data processing component in response to the completion of a data access of the first data processing component to the memory region.

Abstract: One aspect relates to a computer system including a first data processing unit, a second data processing unit and a data transmission/memory device. The data transmission/memory can transmit sets of data from the first data processing unit to the second data processing unit. The data transmission/memory device includes a first memory region and a second memory region.

Abstract: The cache memory is particularly suitable for processing images. The special configuration of a memory field, an allocation unit, a write queue, and a data conflict recognition unit enable a number of data items to be read out from the memory field simultaneously per cycle, in the form of line or column segments. The format of the screen windows that are read out can change from one cycle to another. With sufficient data locality, time-consuming reloading operations do not damage the data throughput since the access requests are pipelined.

Abstract: A truck for a railway vehicle has a truck frame with four individual wheels, which are mounted so that they can rotate around horizontal axles, and whereby one wheel pair is driven. To be able to negotiate tight curves with minimal wear, maximum safety and low construction costs, and to be able to achieve higher speeds on straight segments of track, the driven wheel pair can be steered radially with respect to the curve around a common vertical axis as a function of a setpoint determined by a sensor system, while the non-driven individual wheels are combined into a self-steering individual wheel module so that they can each pivot around their own vertical axes, and can be coupled together so that they are synchronized by means of a steering device.

Abstract: On a railway vehicle with a car body and a truck with an undercarriage, the car body is supported on the truck by means of connecting devices. To achieve increased operating safety even in the event of a malfunction or failure of the connecting devices, the actuator is fastened rigidly on one end to the truck, and is connected to the car body by means of the mechanical series system consisting of a ball-and-socket joint and a sliding connector.

Abstract: The apparatus has a multiplicity of control modules which are assigned to a multiplicity of processing modules for driving purposes. These separate control modules are driven by a superordinate controller and are synchronized by a common synchronization unit on the basis of, by way of example, handshake lines and semaphores. The effect achieved by such an apparatus is that the transmission bandwidth between an external instruction memory and the large-scale integrated system can be reduced, and the total power loss can be lowered by intermittently disconnecting processing modules which are currently not needed. Furthermore, such an architecture supports the separate development of control programs for the individual control modules.

Abstract: A coupling element unit with spring action is located between a car body and an undercarriage of a railway vehicle. To largely relieve the coupling element unit from forces that act at a right angle to the suspension direction, a sliding adapter is provided that has two sliding elements and that can be displaced with respect to one another parallel to a floor of the car body.

Abstract: A rail vehicle equipped with a support actuator of variable vertical length mounted between a vehicle body and a running gear located underneath. In order to maintain an operational supporting device and adequate ride comfort after a failure or overload of the support actuator, an emergency spring coaxial with the support actuator is provided, which only becomes effective when the stroke of the support actuator falls short of a preset value.

Abstract: A running gear for a rail vehicle having sprung longitudinal members of plastic, connected to one another by means of a cross-member structure and at their free ends to axle-boxes for rail wheels. In order to obtain optimal stability of the wheelset guidance with reduced loading of the sprung longitudinal members, the longitudinal members each has at least two flexural springs between the ends of which in each case an axle-box is fixed in symmetrical arrangement.

Abstract: A multiple-unit railway vehicle having three car bodies where the respective neighboring car bodies are each connected in a pivoting manner to one another by means of a single coupling, and each car body sits only on one two-axle truck. In the vicinity of the respective center pivot and possibly also on the trucks, there are actuator elements that are used to influence the articulation angle between the longitudinal axes of the car bodies.

Abstract: The subject matter of the application essentially relates to a matrix array of processor units, each processor unit having, in addition to an arithmetic logic unit and a result register bank, a further arithmetic logic unit, a multiplier/adder unit, a storage unit of a distributed screen section buffer and a local general purpose memory. The processor is distinguished by a high processing speed in conjunction with a small chip area and enables real-time processing even in the case of computation-intensive image processing methods such as 2D convolution, Gabor transformation, Gaussian or Laplacian pyramids, block matching, DCT or MPEG2.

Abstract: A bogie for rail vehicles, in particular a driven bogie, with a bogie frame, includes two or more wheelset units each of which comprises at least one drive unit and/or brake unit. The wheeset units are connected with the bogie frame via a primary suspension. A secondary suspension connects a vehicle body with the bogie frame. A rigid connecting link extends from at least one of the wheelset units for connecting the bogie to the vehicle body. The rigid connecting link is coupled to the wheelset unit at its virtual center of rotation. Where practical, the center of rotation and the center of mass are coincident to minimize the moment of inertia of the wheelset units.
