Abstract: A monitoring apparatus for monitoring of an electrical energy source features one measuring circuit for each pole of the energy source, which is designed to connect the particular pole via a voltage divider to the reference potential.

Abstract: An antenna features a plurality of single emitters which in the x- and y-direction form an antenna array with an aperture. The single emitters are separated from each other by separating walls. At least a portion of the separating walls features an interference site that interrupts the otherwise planar aperture in the z-direction. However, the separating walls which cross the x-direction (and thus separate neighboring single emitters in the x-direction) differ from the separating walls in the y-direction with respect to their wall thickness. In addition, the single emitters feature a separation in the x-direction of less than A. The x-, y- and z-directions are each aligned orthogonal to each other. Due to the asymmetrical wall thickness the single emitters in the x-direction can be placed more closely to each other, so that when using the phase-controlled single emitters the emission characteristic can be displaced in this x-direction.

Abstract: The present disclosure relates to a process for integrally joining an electrical line to an electric contact part by means of a material bond. An exposed end of the line is inserted into a receiving sleeve of the contact part.

Furthermore, the disclosure also concerns an electrical line arrangement which is manufactured with the aid of the metal filler material.
