Abstract: A control unit for use in the engine compartment or in the transmission of a motor vehicle. The control unit has a line section for an engine or transmission fluid, a circuit carrier, and a base plate. The base body is mounted on the base plate. The circuit carrier is arranged between the base body and the base plate. The base body has a plurality of parallel channels each having a respective outlet. At least one of the plurality of parallel channels forms a portion of the line section. A separate cover is mounted on the base body, the cover having a single inlet coupled to the plurality of parallel channels. The cover is, other than only the inlet, connected to the base body in a fluid-tight manner, and the inlet is the only fluid passage through the cover.

Abstract: A method to compensate for the magnetic field heterogeneity inside an object of investigation in a MR device obtains an uncorrected magnetic field distribution of the object and executes an MR sequence with a desired k-space coverage by applying RF pulses to generate a transverse magnetization within the object. MR signal data is recorded, magnetic field shimming parameters are dynamically updated and MR signal data are reconstructed to produce images or localized spectroscopic data. Artifacts in a reconstructed image resulting from an uncorrected magnetic field distribution are suppressed by temporally separating MR signals originating from at least two different sub-volumes within a volume of transverse magnetization by generating a nonlinear phase distribution within the object and by dynamically updating shimming parameters to compensate for the field inhomogeneity distributions within the different sub-volumes in the volume of transverse magnetization.

Abstract: A controller for a motor vehicle with a carrier plate for receiving a component carrier with a component carrier foot. The carrier plate has a recess through which the component carrier can be passed and which is suitable for receiving the foot, wherein the dimensions of the recess in the region of the component carrier and in the region of the foot in the X/Y-direction correspond to maximum admissible dimensions of the component carrier and of the foot (5) in the X/Y-direction. In the Z-direction, a pressing geometry is arranged on the recess or on the foot such that after establishing a positive-fit or non-positive connection between the carrier plate and a system interface, the pressing geometry or a part that is arranged opposite the pressing geometry is in such a deformed state that the foot is in the recess in a fixed state and without play.

Abstract: A sensor arrangement has a sensor element. A contact element is in electrical contact on the one hand with the sensor element and on the other with contact pins. The contact element is insert moulded with a plastic body. Affixing positions to which the contact element has been affixed, and on which the contact element is exposed respectively have one collar made of plastic material which runs around the exposed areas of the contact element. A sensor arrangement results for which the cost of manufacture is lower than that of the prior art, while the same security against unwanted electrostatic discharging or against the formation of an unwanted short circuit remains.

Abstract: An arrangement of an electronic component in a plastic housing, including a cover and a lower part, and to a method for fixing the electronic component in the housing. The cover is connected to the lower part and exerts a pre-defined force (F) on the electronic component. The cover is designed such that the influence of the height tolerance (dh) of the electronic component on the force (F) can be compensated to the effect that, once the cover has been mounted, the force (F) applied to the lower part is in a pre-defined force range (B).

Abstract: A housing for retaining an electronic component, including a lid and a lower part made of synthetic material, wherein the lid is joined in a force-fit manner to the lower part by clamping geometry, and in order to affix the electronic component in position, the lid applies a specified force (F) to the electronic component after being joined to the lower part due to its design. Here, the lid is designed in such a manner that the force (F) applied lies within a specified force range (B), and that the clamping geometry comprises a groove on the lower part and a ridge on the lid which grips into the groove, wherein a clamp web on the lower part or on the lid is arranged in such a manner that the lid is removably clamped to the lower part after being joined to the lower part with a force (F) which acts parallel to the clamping force (KF).

Abstract: The pursuit for ever higher field strengths and faster data acquisitions has led to the construction of coil arrays with high numbers of elements. With the SENSE technique it has been shown, how the sensitivity of those elements can be used for spatial image encoding. A method in accordance with the present invention, largely abstains from using encoding gradients. The resulting sensitivity encoded free induction decay (FID) data is then not used for imaging, but for determining field inhomogeneity distribution. The method has therefore been termed SSH for Sense SHimming.
