ABSTRACT:
A device for automatic transmission of information includes an information emitter and an information seeker wherein the information is transmitted from the emitter to the seeker in response to an interrogating signal from the information seeker. The emitter relies for transmission on energy which is extracted from the interrogating signal. The emitter is provided with several resonant circuits, each of which generates an information signal component. The information carrying signal comprises a multitude of such signal components. From the information carrying signal the information is captured by detection in the information seeker of the respective information signal components.
