Abstract: A method for aligned parking of a trailer. The method includes: determining a topography of a ground surface of an environment of the trailer; determining a distance of contact points of at least two wheels of an axle of the trailer; determining at least one pair of target positions on the ground surface of the environment of the trailer, for transversely aligned parking of the trailer, on the basis of the distance of the contact points of the at least two wheels of the axle of the trailer and the topography of the ground surface of the environment of the trailer; and providing the at least one pair of target positions, for aligned parking of the trailer.

Abstract: In an electrode combination for a radiation head for the generation of electromagnetic radiation comprising an anode means having a tip end component and a cathode means, the tip end component comprising a material able to facilitate, in response to a predetermined pulse voltage applied between the anode means and cathode means, the generation of electromagnetic radiation, the improvement wherein the electrode combination comprises a trigger electrode, the tip end component, the cathode means and the trigger electrode being spaced apart from each other by a respective predetermined distance.
