Abstract: A ground contact unit for a vehicle battery charging system, having a ground-side base and an upper outer wall, wherein a receiving space in which at least one printed circuit board is positioned is formed between the base and the outer wall, and having a plurality of contacts provided on the outside of the outer wall for contacting vehicle-side mating contacts, the contacts being electrically conductively connected to the printed circuit board by means of electrical lines, wherein the lines are formed, at least in sections, by flexible, freely extending contact bridges which are configured to undergo a spring deflection toward the base.

Abstract: An emitter arrangement contains at least one emitter and at least one vaporizer element spaced apart therefrom. At least one of the emitters contains at least one emission surface made of at least one first electron emission material and lies at a first potential. At least one of the vaporizer elements contains one evaporation surface made of at least one second electron emission material and lies at a second potential. Thus, the emitter arrangement has a compact configuration and a longer lifetime with simultaneously good emission properties.

Abstract: An emitter has a basic unit with at least one emission surface. Accordingly, the basic unit has deep structuring in a region of the at least one emission surface. More specifically, the basic unit has the deep structuring on both a front side and on a rear side in the region of the emission surface for improving emission properties.

Abstract: A method and a device to offset stack pages of successive print or copy jobs that are supplied to a page output unit as a page stream. The pages of the successive second job are offset stacked over the pages of the preceding first job and are spatially displaced with regard to the pages of the first job. After the offset stacking of the first job, the uppermost page of the first page stack is mechanically fixed to the first page stack.
