Abstract: A dosing unit for dosing fluids includes a fluid guiding module having a fluid inlet and a fluid outlet, a solenoid valve for controlling or regulating a fluid flow through the fluid guiding module, and a dosing tip, the fluid outlet of the fluid guiding module leading to the fluid inlet of the dosing tip, and the dosing tip having an elastic, self-closing outlet nozzle. Furthermore, a dosing station and a dosing tip are specified.

Abstract: An audio decoder configured to produce an audio signal from a bitstream containing audio frames includes: a core band decoding module configured to derive a directly decoded core band audio signal from the bitstream; a bandwidth extension module configured to derive a parametrically decoded bandwidth extension audio signal from the core band audio signal and from the bitstream, wherein the bandwidth extension audio signal is based on a frequency domain signal having at least one frequency band; and a combiner configured to combine the core band audio signal and the bandwidth extension audio signal so as to produce the audio signal; wherein the bandwidth extension module includes an energy adjusting module being configured in such way that in a current audio frame in which an audio frame loss occurs, an adjusted signal energy for the current audio frame for the at least one frequency band is set.

Abstract: A calibration tool for fabricating disk springs. The tool includes a circular cylindrical tool body having an insertion bevel at its face end portion for receiving and centering a workpiece within an inner circumferential enveloping surface of the tool body. A tool surface at the inner circumferential enveloping surface aligns the workpiece relative to a forming tool disposed within the inner circumferential enveloping surface. The tool surface includes a first portion having an inner diameter that increases in size along the axial longitudinal direction of the tool body, and a second portion with an inner diameter that decreases in size along the axial longitudinal direction of the tool body.
