  • Device for transporting a medium and assembly method
    Patent number: 11939997
    Abstract: A device for transporting a medium includes at least one channel which extends in an axial direction and through which the medium is guided. The channel is enclosed by an electrically conductive inner envelope that is connected to a first potential equalization conductor. An electrically conductive outer envelope is provided between the channel and an electrically conductive outer casing and is connected to an electrically conductive second potential equalization conductor. Arranged between the channel and the outer envelope is an electrically insulating intermediate layer which is produced from heat-insulating material.

  • Method and apparatus for controlling a relay
    Patent number: 11367579
    Abstract: In a method for controlling a relay with a relay contact, switching as an opening operation or a closing operation at the relay is temporally captured with respect to accurate opening or closing of the relay contact in comparison with a switching voltage zero crossing of a switching voltage to be switched. An actual switching time is determined and is corrected by means of further capturing of switching operations. A microcontroller is used for this purpose, and the signals can be digitally captured, that is to say at an A/D input.
