| 20090091403 | CONTACTLESS TRANSMISSION OF A DIFFERENTIAL SIGNAL BETWEEN A TRANSMITTER AND A RECEIVER - A method for the contactless transmission of at least one differential signal between a transmitter and a receiver given the existence of at least one common-mode noise signal, which has a low frequency in comparison with at least one signal to be transmitted, is provided. The suppression of at least one common-mode noise signal within the receiver a ground reference potential assigned to the receiver is separated into two ground reference potentials decoupled from one another. At least one common-mode noise signal may be suppressed by a filter unit at the input of a receive amplifier of the receiver. | 04-09-2009 |
| 20090257206 | HOLDING APPARATUS - The invention specifies a holding apparatus comprising a support element and a circuit board. A trench for receiving the circuit board is embodied in the support element. At least one first clamping element is arranged on one or both longitudinal sides of the circuit board and/or at least one second clamping element is arranged in the trench. As a result, the circuit board received by the trench is fixed in the trench in a clearance-free fashion. | 10-15-2009 |
| 20100226479 | MULTICATHODE X-RAY TUBE - An improved x-ray tube that includes a plurality of cathodes in a region under vacuum is provided. Several wirelessly activatable elements, which are each assigned to a cathode or a group of cathodes, are arranged in the region under vacuum and make an electrically conducting connection of the cathode or the group of cathodes to a cathode control voltage line when receiving a control signal from outside of the region under vacuum. A system that includes the improved x-ray tube and several transmitter elements for the wireless activation of the wirelessly activatable elements is also provided. | 09-09-2010 |

| 20090251871 | RETAINING FACILITY FOR PRINTED CIRCUIT BOARDS ON CURVED SURFACES - A retaining facility for clearance-free fixing of a printed circuit board onto a one-dimensional curved surface is provided. In the direction of curvature of the one-dimensional curved surface, a tensile or compressive force acts on the printed circuit board or on at least one first connection device connected to the latter, with the printed circuit board being bent and pressed onto the curved surface. In this way the printed circuit board is held solidly and with little vibration on the surface even when acted on by centrifugal forces. | 10-08-2009 |

| 20090130885 | PLUG CONNECTION DEVICE DESIGNED TO CONNECT TWO FUNCTION ELEMENTS FOR SIGNAL AND POWER TRANSMISSION - A plug connection device that connects two function elements for signal and power transmission between the function elements, in particular for medical applications, has connection components fashioned for capacitive connection of the function elements. | 05-21-2009 |
| 20090212774 | ANTENNA ARRANGEMENT FOR A MAGNETIC RESONANCE APPARATUS - In an antenna arrangement for a magnetic resonance apparatus and a method for acquiring magnetic resonance signals, which has at least four individually operable antenna conductor loops arranged like a matrix in rows and columns, wherein two antenna conductor loops adjacent in a row or in a column are inductively decoupled from one another; and wherein two antenna conductor loops diagonally adjacent to one another in adjacent rows and columns are capacitively decoupled from one another. | 08-27-2009 |
| 20110221441 | LOCAL COIL FOR A MAGNETIC RESONANCE DEVICE - A local coil for a magnetic resonance device includes a connector apparatus for establishing a connection to a plug-in station on a patient couch and at least one storage facility. The storage facility may be used to read out by way of the connection and may store at least one non-modifiable data item describing a property of the local coil. The storage facility may include at least one detection facility for acquiring measurement values describing the state of the local coil and at least one evaluation facility configured to modify the readout address of the storage facility as a function of the measurement values. | 09-15-2011 |

| 20100154414 | INTERNAL COMBUSTION ENGINE WITH EXHAUST GAS TURBOCHARGER - An internal combustion engine with an exhaust gas manifold, an exhaust gas line, an exhaust gas turbocharger, by which the compressor provided to charge combustion air for the internal combustion engine is driven, and a bypass line, which branches from the exhaust gas line and in which a power turbine is arranged, wherein a short-circuit line branches from the bypass line and leads to a section of the exhaust gas line located downstream of the exhaust gas turbocharger. In addition, a first valve is positioned in the section of the exhaust gas line located downstream of the exhaust gas turbocharger in such a way that exhaust gas leaving the exhaust gas turbocharger is diverted into the short-circuit line and then to the power turbine. | 06-24-2010 |
