Abstract:
A system for detecting a specific relative position between a reader and a receiver, including: an inductive contactless receiver including an antenna winding and a circuit for selectively modulating a load; an inductive contactless reader including: a transceiver antenna circuit having nonzero mutual inductance with the antenna winding for the position, a communication circuit connected to the transceiver antenna circuit, a receiver antenna circuit having mutual inductance with the antenna winding that exhibits a minimum for the position, and a processing circuit for: identifying presence of a receiver by detecting nonzero mutual inductance between the transceiver antenna circuit and an antenna winding, and detecting a mutual inductance minimum between the receiver antenna circuit and an antenna winding.
