  • Patent number: 10287537
    Abstract: In a clarification method for a beverage liquid, in particular for producing beer, the beverage liquid, after it passes through a fermentation stage, is subjected to a clarification which serves for removing active haze components from the beverage liquid, and fed to a maturation vessel in which the beverage liquid is stored for a maturation time. In a further method step, the beverage liquid is charged with at least one pectin-containing clarification agent for increasing a filtration performance. In this case it is provided that the pectin-containing clarification agent is introduced into the beverage liquid on the path from the fermentation stage to the maturation vessel and the pectin present therein, before the feed to the maturation vessel, is at least for the most part removed again from the beverage liquid.

  • Patent number: 10151783
    Abstract: An apparatus and a method for determining an antenna characteristic of an antenna under test in free space is disclosed. Measurement results of a transmitted power of a measurement signal transmitted between the reference antenna and an antenna under test are detected, wherein detecting takes place in the frequency domain. The detected measurement results are transformed into the time domain and a time-domain filter is applied to the measurement results converted into the time domain. A filter width of the time-domain filter is determined in dependence on a spatial distance between the reference antenna and the antenna under test. Measurement result portions that result due to a multipath propagation of the measurement signal between the reference antenna and the antenna under test are reduced or removed.

  • Patent number: 9945891
    Abstract: A charge measuring device detects focused ion beam attacks on an integrated semiconductor circuit with a capacitor, a field effect transistor, and a charge collecting device all manufactured in the integrated semiconductor circuit and insulated from additional circuit elements. A first pole of the capacitor is conductively connected to the charge collecting device and a gate of the field effect transistor. When a voltage is applied to the second pole of the capacitor, a drain source current flows through the field effect transistor, and a relationship between the voltage and the drain source current is ascertained. A comparison of the relationship with a previously ascertained relationship indicates a change of the charge quantity stored in the capacitor by the charge collecting device.
