Abstract:
1. A device for wireless transmission and evaluation of signals and switching statuses from at least one mobile device ( 10 ) to a second device ( 11 ), where at least one of the devices is capable of moving over a predefined travel path, with a transmission link ( 12 ) between devices ( 10 ) and ( 11 ), with a transmission for feeding the energy supply for mobile device ( 10 ), with at least one sensor device ( 9 ), connected to mobile device ( 10 ), which brings about modulation on transmission link ( 12 ) between the two devices in accordance with a random signal string of the sensor, with a receiving device for modulation in device ( 11 ), wherein a transmission device for transmission across transmission line ( 12 ) comprises at least two coupled coil devices ( 13 , 14 ), which are mechanically and topologically independent of each other, and wherein at least one coil device ( 13 , 14 ) is constructed by plugging together individual, modular coil elements ( 2 ), in order to realize links of any length.
