Vorrichtung zur Übertragung von Daten innerhalb eines Systems zur berührungsfreien induktiven Energieübertragung

摘要

The device uses a primary current conductor (2,7,8) to transfer data in addition to energy. Data are inductively coupled into and out of the primary current conductor. Forward and return conductors or only one of these are used for coupling data in and out. Different logic states are transferred by coupling different frequencies.
