Abstract:
1. A system for transferring information related to an object in an electromagnetic field, comprising: a conductor arrangement which includes multiple conductor components which form an electromagnetic field, and a transmitter associated with the object, the transmitter comprising a microcontroller with impedance altering means for altering an impedance between the object and at least a specific one of the conductor components closest to a position of the object, wherein the impedance altering means is adapted to modulate the electromagnetic field between the specific one of the conductor components closest to the position of the object, and also between the object and other conductor components which are further away from the position of the object, wherein the system is adapted to locate the position of the object in an area of the conductor arrangement by measuring the impedance between the specific one of the conductor components and the other conductor components of the conductor arrangement.
