Abstract: The invention relates to a method for testing an electrode arrangement (1) for generating a non-thermal plasma, having the following steps: determining at least one power parameter which characterizes a plasma power of the electrode arrangement (1); comparing the at least one power parameter with at least one predetermined target parameter value, and obtaining a comparison result; assessing the functionality of the electrode arrangement (1) on the basis of the comparison result, and preferably selecting at least one action according to the comparison result.

Abstract: The invention relates to an apparatus for influencing the movability of a door which can be moved between a closed position and an open position, in particular of a motor vehicle, which apparatus comprises a sensor system for determining the door position and/or the door moving speed, an actuating device for setting a resistance to movement of the door, and a control device for controlling the actuating device as a function of the determined door position and/or the door moving speed.
