20100056902PATIENT POSITIONING COUCH AND MEDICAL DEVICE WITH A PATIENT POSITIONING COUCH - A patient positioning couch includes an illumination apparatus having at least one light source that is arranged in the patient positioning couch. The patient positioning couch is capable of being placed in an examination area of a medical device. Through the arrangement of the at least one light source of the illumination apparatus of the patient positioning couch, it is always ensured that the illumination does not lose its location relative to a patient or another object positioned on the patient positioning couch, even if the position of the patient positioning couch changes, e.g. if the patient positioning couch is moved into or out of the examination area. At the same time an especially space-saving illumination of the examination area can thus be achieved.03-04-2010
20100109668Medical Examination or Treatment Facility, in Particular a Magnetic Resonance Facility - A medical examination or treatment facility is proposed. The medical examination or treatment facility, which is a magnetic resonance facility in particular, comprises a main unit and a support structure that can be fastened to the main unit, the support structure being a profile frame structure. Because of their particular form profile frames allow a wide range of components to be fastened without major outlay. They are simple, stable and flexible to use and allow a significant cost reduction compared with conventional steel structures. The profiles in the profile frames allow changes to be made easily to the arrangement of fastened parts at any time by moving fastening units in the profile frames.05-06-2010
20100310304METHOD FOR THE RELEASABLE FASTENING OF A COMPONENT TO AN APPARATUS AND CORRESPONDINGLY CONFIGURED FASTENING SYSTEM - A method and a fastening system for the releasable fastening of a component to an apparatus are described. Here the fastening system comprises a detent spring arranged on the apparatus, a detent pin with a groove arranged on the component and a Bowden cable arranged on the apparatus. If the component is fastened to the apparatus, the detent spring locks in the groove in a locking position. The Bowden cable is connected to the detent spring such that when pulling on the Bowden cable, the detent spring releases from the locking position in the groove, as a result of which the fastening of the component to the apparatus is released.12-09-2010
20110291656MAGNETIC RESONANCE APPARATUS COMPRISING A FASTENING ELEMENT FOR ATTACHING A NOISE-INSULATING ELEMENT AND A METHOD FOR ATTACHING A NOISE-INSULATING ELEMENT - A magnetic resonance apparatus is provided. The magnetic resonance apparatus comprises a gradient coil unit, a housing cover and a noise protection unit which has at least one noise-insulating element which is arranged between the gradient coil unit and the housing cover for deadening an operating noise of the gradient coil unit. The magnetic resonance apparatus also comprises at least one fastening element for attaching the at least one noise-insulating element. The fastening element engages in a connection with the gradient coil unit for attaching the at least one noise-insulating element.12-01-2011
20120018593CABLE TRANSPORT CARRIER FACILITY AS WELL AS A SYSTEM WITH A MEDICAL IMAGING FACILITY AND A CABLE TRANSPORT CARRIER FACILITY - A cable transport carrier facility is proposed. The cable transport carrier facility is designed for transport of system cables installed on a medical imaging facility and is able to be installed on the medical imaging facility. The cable transport carrier facility has at least one component which is made at least partly of an organic material.01-26-2012
20120046537Medical Imaging Device - A medical imaging device having a tubular receiving region to receive a patient on a patient couch is proposed. The medical imaging device has a wall at least partially enclosing the receiving region. The medical imaging device features a film disposed on the wall at least partially enclosing the receiving region for generating at least one virtual image. The virtual image refers to a visual mapping of a light-reflecting object and/or an illuminated object.02-23-2012

20090044212Assembly with a vibration-isolated cover - An inventive vibration-generating device comprises a cover and isolating device arranged between the cover and the assembly. The isolating device reduces the propagation of vibrations from the vibration-generating assembly to the outer casing of the cover and is hereby supported according to the embodiment so that they float in relation to the assembly and/or the cover.02-12-2009
20090121088Pipe/cable enclosure and method for enclosing pipes and cables - The invention relates to a pipe/cable enclosure for pipes and cables of a medical diagnostic device, said enclosure surrounding the pipes/cables running from the diagnostic device to a partition wall and having at least one folding wall element with folds which, in the assembled state, is disposed folded at the folds around the pipes/cables, thus surrounding the pipes/cables.05-14-2009
20090178255Retaining device - An inventive retaining device which can be adjusted in three spatial directions, in particular for fastening a first component to a second component, includes a first plate, which can be fixedly connected to the second component, as well as a second plate, which can be adjusted in a first spatial direction relative to the first plate, and a third plate, which can be adjusted in a second spatial direction relative to the second plate and a centering pin, which can be fixedly connected to the first component and can be adjusted in a third spatial direction relative to the third plate. The inventive retaining device allows a particularly flexible regulation of tolerances and facilitates an assembly and/or disassembly of the components.07-16-2009
20090260917Cladding part for component - The invention relates to a cladding part for components. The cladding part has at least two areas with different vibration damping properties. The different areas make it possible in a simple manner to meet partly conflicting requirements for cladding parts of the components in an optimum manner. The components include medical examination devices.10-22-2009

20090131243METHOD FOR THE REACTIVATION OF THERMALLY AGED NITROGEN OXIDE STORAGE CATALYTIC CONVERTERS - Nitrogen oxide storage catalysts are used for removing the nitrogen oxides present in the lean-burn exhaust gas of lean-burn engines. Here, the purifying action is based on the nitrogen oxides being stored in the form of nitrates by the storage material of the storage catalyst during a lean-burn operating phase of the engine and the previously formed nitrates being decomposed in a subsequent rich-burn operating phase of the engine and the nitrogen oxides which are being liberated again being reacted with the reducing exhaust gas constituents over the storage catalyst to form nitrogen, carbon dioxide and water. Storage catalysts are thermally aged by high temperatures. The aging is due to sintering of the catalytically active noble metal components of the catalyst and to formation of compounds of the storage components with the support materials. According to the invention, the formation of compounds of the storage materials can be largely reversed by treatment of the storage material with a gas mixture comprising nitrogen dioxide and/or carbon dioxide and water vapor at temperatures of from 300 to 500° C. The reactivation can be carried out either directly on the vehicle by setting appropriate exhaust gas conditions or during a routine service by removal of the catalyst from the vehicle and treatment with a gas mixture in an appropriate apparatus.05-21-2009
