Abstract: An x-ray tube unit includes an x-ray tube unit housing, in which a vacuum housing is disposed, which includes a high-voltage component. The vacuum housing includes an insulating medium circulating in the x-ray tube unit housing flowing around it. Further, a cathode module and an anode are disposed in the vacuum housing, the cathode module lying at high voltage and including an emitter which emits electrons when heating current is fed to it.

Abstract: An x-ray tube has a backscatter electron trap to prevent extra focal radiation caused by backscattered electrons from the focal spot from passing through the beam exit window to an exterior of the x-ray tube. The backscatter electron trap has a surface that faces the x-ray beam in the x-ray tube. No portion of that surface is visible both from an arbitrary point in the x-ray beam outside of the x-ray tube and from an arbitrary point at the focal spot.

Abstract: A computed tomography system has a gantry with a rotor side that can be rotated around a system axis during operation, at which at least one x-ray tube is mounted. To cool the at least one x-ray tube a liquid cooling system is equipped with a fluid volume filled with cooling liquid, the fluid volume extends over distances of different sizes from the system axis. The fluid volume is located on the rotor of the gantry and thus is exposed to centrifugal force during operation. To increase pressure in the cooling system, a flexible compensation volume and a movable mass element that rotate with the gantry are provided. The mass element is arranged such that the centrifugal force acting on the mass element during operation causes pressure to be exerted on the cooling liquid.

Abstract: A parking brake device for motor vehicles is described, having an operator control element and at least two electromechanical actuators for generating a parking braking force at in each case one wheel of the motor vehicle, and having in each case one wheel actuation unit per electromechanical actuator, and a further control unit. The further control unit is connected here, on the one hand, to the operator control element and, on the other hand, in parallel to each wheel actuation unit via at least one parking brake data bus. The further control unit applies control signals to the wheel actuation units, and a safety element is provided which ensures reliable operation of the parking brake device with wheel control units with, in each case, one microcontroller.

Abstract: The present invention relates to a correction of image status information assigned on a local basis to a video image. Upon evaluating a predefined image portion comprising a plurality of image elements, incorrect determinations are detected and eliminated.

Abstract: The present invention enables to determine a film mode characteristic for individual image areas in order to appropriately reflect local image characteristics. By detecting the image characteristics on a local basis, a picture improvement processing achieves better results as artefacts due to the application of a wrong global improvement processing are avoided.

Abstract: The present invention enables an improved film mode determination, in particular for border areas of moving objects. This is achieved by a film mode extrapolation. The film mode indication of the current block is extrapolated in accordance with a motion vector determined for the identical block. In this manner, the accuracy of the film mode determinations for the current image can be improved and image processing yielding improved picture quality can be improved accordingly.

The removal of irregularities enables a respective improved image processing, for instance, interpolation processing during up-conversion.

Abstract: A blank for forming a parallelepipedal box or a parallelepipedal box element is constructed with a removal strip in such a manner that parallel tear lines extend through three connected wall sections of the blank. The tear lines end in one wall section at an articulation area. The tear lines delimit the removal strip which can be torn out of a finished pack or box and upon which a pulling force can be exerted in such a manner that the removal strip is bent about the articulation area, thus causing objects to be lifted from the box by the removal strip.

Abstract: An inverted U-shaped hollow rectangular tube has clamps at its ends for securing the same to the rain gutter of a vehicle. Openings in the tube removably receive selected load supports and a slide bar in the tube engages the load support to prevent its removal. Locks prevent release of the slide bar and cover the clamps to prevent their unauthorized release.
