Abstract: An energy supply unit includes a primary coil which is at least indirectly connected to an energy source. In a secondary coil which is at least indirectly connected to the control circuit, and an insulating section formed between the primary coil and the secondary coil. The auxiliary energy is transmitted via the insulating section by way of a magnetic alternating field. The energy supply unit further includes a first carrier plate, a primary coil embodied as a flat coil situated on the first carrier plate, a second carrier plate, and a secondary coil embodied as a flat coil situated on the second carrier plate. The insulating section is embodied as an interferric space formed between the primary coil and the secondary coil.

Abstract: The invention relates to a waiting time prediction system for visualizing waiting times until the arrival of at least one vehicle (2), in particular a vehicle of the public transit system, at at least one station stop (5). Hardware and/or software expenses are minimized by including the following components: a first device for determining position data of the vehicle (2), a second device for calculating the remaining expected driving time until the arrival of the vehicle (2) at the station stop (5) based on the measured position data of the vehicle (2) and the known coordinates of the station stop (5), and first and second transmission means for transmitting information from the first device to the second device and from the second device to a station stop display (4), wherein the station stop display (4) can be controlled by this second transmission means to indicate the waiting time.
