Abstract: A semiconductor module includes a substrate composed of electrically insulating material. A structured metal layer for contact with an electrical component is applied to a top side of the substrate. The structured metal layer is applied to the substrate only in a central region of the substrate, so that an edge region which surrounds the central region and in which the structured metal layer is not applied to the substrate remains on the top side of the substrate. A contact layer for making contact with a cooling body is situated opposite the structured metal layer and applied to a bottom side of the substrate in the central region. A structured supporting structure is further applied to the bottom side of the substrate in the edge region and has a thickness which corresponds to a thickness of the contact layer.

Abstract: A method and apparatus for determining a trajectory of a robot's end effector are disclosed. In an embodiment, the apparatus includes a force obtaining device to obtain a collision force of the end effector of the robot, caused by a collision of the end effector upon the collision being detected; and a trajectory determining device to determine a second trajectory of the end effector based on the collision force of the end effector obtained, and based on a recorded first trajectory of the end effector. The recorded first trajectory is a trajectory recorded before the collision, and the second trajectory is a trajectory determined after the collision. As such, an efficient protection for the robot and its working environment at the moment of collision may be achieved.

The elevated pressure reduces power consumption for the cell at least in part by reducing the formation of gas bubbles, which typically leads to increased resistance and an increased power output.

Abstract: A method is for displaying position information relating to a position of a region of interest of a patient relative to an examination unit of an imaging apparatus. A first examination plane is assignable to the examination unit and a camera is disposed relative to the examination unit such that, via a lens of the camera, three non-collinear reference points lying in a first reference plane parallel to the first examination plane are mapped to three collinear first image points lying on a first line. In an embodiment, the method includes capturing a camera image of the region of interest via the camera; displaying a positioning image, the positioning image including the camera image; and displaying first marking information relating to a position of the first line in the positioning image.

Abstract: The embodiments relate to a method for producing a digital volume model of a body volume by a sensor device, which sensor device includes a plurality of radiation sensors, of which each produces a pixel value in a projection. In order to produce the volume model, a plurality of projections from different projection angles (a) are produced and the volume model is computed from sensor positions of the radiation sensors and pixel values of the radiation sensors. For at least one projection angle (a), the sensor positions are corrected by a respective correction vector for rigid motion compensation. The problem addressed is that of also compensating the non-rigid motion of the body volume (i.e., the deformation) in the computation of the volume model.
Abstract: A turbine assembly with a hollow aerofoil having a main cavity with an impingement tube, insertable inside the main cavity for impingement cooling of an inner surface of the main cavity, and a platform at a radial end of the hollow aerofoil, and a cooling chamber for cooling the platform arranged relative to the hollow aerofoil on an opposed site of the platform. The cooling chamber is limited at a first radial end by a wall segment of the platform and at an opposed radial second end from a cover plate. The impingement tube extends in span wise direction through the cooling chamber from the platform to the cover plate and restricts a sub-cavity of the main cavity. The wall segment includes an entry aperture for a cooling medium to enter from the cooling chamber of the platform into the sub-cavity of the hollow aerofoil.
Abstract: Shear wave characteristics are estimated from analytic data. Measures of displacement are converted into complex representations. The magnitude and/or phase components of the complex representation may be used for estimating various characteristics, such as velocity, center frequency, attenuation, shear modulus, or shear viscosity. The zero-phase of the phase component represents an occurrence of the shear wave at that location.

Abstract: A system and method for optimizing customer magnetic resonance systems is provided. An automation system gathers data from a geographically dispersed network of installed magnetic resonance systems, which data is mined and analyzed in order to recognize patterns about the best practices of the installed base. Customer-specific variables for customer magnetic resonance systems are then optimized, based on the recognized patterns. More particularly, customer specific protocols and hardware/software configurations can be calculated and optimized, by making use of data mined from best-in-class customers having similar profiles.
Abstract: Pose of a probe is detected in x-ray medical imaging. Since the TEE probe is inserted through the esophagus of a patient, the pose is limited to being within the esophagus. The path of the esophagus is determined from medical imaging prior to the intervention. During the intervention, the location in 2D is found from one x-ray image at a given time. The 3D probe location is provided by assigning the depth of the esophagus at that 2D location to be the depth of the probe. A single x-ray image may be used to determine the probe location in 3D, allowing for real-time pose determination without requiring space to rotate a C-arm during the intervention.
