Abstract: Apparatuses and methods of the present disclosure integrate a non-intrusive current sensor in the form of a current mismatch sensor into a power module having paralleled semiconductor structures or components. The current mismatch can be detected by the current sensor by monitoring a magnetic flux density between the paralleled components or devices.

Abstract: In a method for masking one or more regions surrounding an anatomical region of interest for each of one or more MRI images obtained from MRI imaging data, the one or more regions surrounding the anatomical region of interest are masked based on control data determined for identifying the anatomical region of interest in the MRI imaging data. The MRI imaging data may be obtained during an MRI exam of a patient for a measurement volume including the anatomical region of interest. The anatomical region of interest may be ascertained before performing the MRI exam.

Abstract: A door handle for actuating a mortise lock of a door with an output shaft and a handle facing away from the door. The output shaft and the handle have a common rotation axis and are connected to one another via an electromechanical clutch. The output shaft has a recess, on the side facing the handle, dimensioned for a coupling element that is axially displaceable between open and closed positions with a motor, while the handle has a receptacle dimensioned to accommodate the coupling element opposite to the recess. The door handle is particularly reliable when the motor drives a coupling (auxiliary) shaft on which and/or in which at least one coil spring is disposed non-rotatably and coaxially with respect to the stator of the motor. The auxiliary shaft has at least one protrusion engaging in an intermediate space between two neighbored windings of the coil spring to displace the coil spring axially as a result of rotation of the auxiliary shaft.

Abstract: The invention relates to a method for the manufacture of a ceramic component of desired final geometry using at least a cellulose-containing semi-finished moulded part, which is pyrolysed in non-oxidizing gas atmosphere. In order to manufacture complex components, it is suggested that at least two semi-finished moulded parts are firmly joined either in raw form or after at least partial carbonisation. The joined moulded parts are subsequently machined to achieve the desired final geometry or a geometry corresponding to the desired final geometry plus the machining allowance. Then, the carbon parts are available after carbonisation of the moulded parts in non-oxidizing atmosphere. Alternatively, these can be converted into a CMC composite material in a non-oxidizing gas atmosphere by a metal infiltration process with simultaneous reactive joining of at least two moulded parts.

Abstract: Aqueous dispersion containing a metal oxide powder with a fine fraction and a coarse fraction, in which—the metal oxide powder is silicon dioxide, aluminum oxide, titanium dioxide, zirconium dioxide, cerium oxide or a mixed oxide of two or more of the aforementioned metal oxides,—the fine fraction is present in aggregated form and has a mean aggregate diameter in the dispersion of less than 200 nm,—the coarse fraction consists of particles with a mean diameter of 1 to 20 ?m, —the ratio of fine fraction to coarse fraction is 2:98 to 30:70, and—the content of metal oxide powder is 50 to 85 wt. %, referred to the total amount of the dispersion. The aqueous dispersion is produced by a process comprising the steps:—production of a fine fraction dispersion by dispersing the pulverulent fine fraction in water by means of an energy input of at least 200 KJ/m3?, and—introducing the coarse fraction in the form of a powder into the fine fraction dispersion under dispersing conditions at a low energy input.
