Anode applicators include consumable anodes, that can be operated in a non-stationary mode and are insensitive to orientation, are used in selective platingbrush electrodeposition of coatings or free-standing components. The floor anchor comprises a hollow shaft segment having an external thread at least in segments, and a head segment adjacent to the shaft segment and facing downward in the anchored state in the floor. A context of the first change is determined. In another exemplary embodiment, operation of the transponder-reader payment system may be controlled by an activation circuit. The device has the advantages of applicability to lightweight, thin and low-voltage driving displays, good luminescent capacity attenuating little even in long-term driving operation, and good durability.
