Abstract: A method of producing a permanent magnet includes forming a magnetisable workpiece by additive manufacturing and forming the permanent magnet by partitioning the magnetisable workpiece. The additive manufacturing includes steps of forming a first powder layer by depositing a first powder, the first powder being ferromagnetic; forming a first workpiece layer of the magnetisable workpiece by irradiating a predetermined first area of the first powder layer by means of a focused energy beam to fuse the first powder in the first area; and repeating the above steps multiple times to form further workpiece layers of the magnetisable workpiece. The permanent magnet is formed by partitioning the magnetisable workpiece, where an exposed surface of the permanent magnet formed by the partitioning is non-parallel to the first workpiece layer, and where the permanent magnet produces an external magnetic field having a magnetic field strength of at least 1 kA/m.

Abstract: An arrangement (2) to calibrate a capacitive sensor interface (1) includes a capacitive sensor (10) having a capacitance (cmem, cmemsp, cmemsm) and a charge storing circuit (20) having a changeable capacitance (cdum, cdump, cdumm).

A control circuit (60) is configured to trim the capacitance (cdum, cdump, cdumm) of the charge storing circuit (20) such that the level of the output signal (Vout) tends to the level of zero.

Abstract: A MEMS sensor (1) comprises a MEMS transducer (10) being coupled to a MEMS interface circuit (20). The MEMS interface circuit (20) comprises a bias voltage generator (100), a differential amplifier (200), a capacitor (300) and a feedback control circuit (400). The bias voltage generator (100) generates a bias voltage (Vbias) for operating the MEMS transducer. The variable capacitor (300) is connected to one of the input nodes (I200a) of the differential amplifier (200). At least one of the output nodes (A200a, A200b) of the differential amplifier is coupled to a base terminal (T110) of an output filter (110) of the bias voltage generator (100). Any disturbing signal from the bias voltage generator (100) is a common-mode signal that is divided equally on the input nodes (I200a, I200b) of the differential amplifier (200) and is therefore rejected.

Abstract: An annular combustor includes an inner liner shell and an outer liner shell defining an interior volume through which combustion gases flow in a gas flow direction from a forward end to an aft end. A cooling shroud is attached radially outward of the inner liner shell, forming a cooling passage between the inner liner shell and the cooling shroud. The cooling passage directs air in an air flow direction opposite to the gas flow direction. The cooling shroud is assembled from circumferentially adjoined cooling shroud segments, and the distance between the cooling shroud segments and the inner liner shell is greater at the forward end than at the aft end. Fastening elements are distributed across an axial length of the cooling shroud segments in circumferentially staggered rows. Each forwardmost fastening element is disposed immediately adjacent to a curved portion at the forward end of each respective cooling shroud segment to reduce vibration.
