Abstract (en)
[origin: EP1454769A1] The device has a transponder circuit (1) with a coil, placed on an object turned around an axis of rotation passing through the object. An interrogation circuit (3) has another coil and is placed on a structure to which the object is linked. A cross coupling coil (2) with one turn is mounted on the structure/object coaxially to the axis. The coupling coil serves as an interface of inductive coupling between the two coils.
