Abstract
A device for generating a magnetic field in a goal area with at least two coils arranged in parallel to a goal area defined and bounded by a goal, wherein a first coil is attached in an area behind the goal and a second coil is attached closer to the goal than the first coil or identical to the goal, wherein the first coil and the second coil respectively have a coil impedance, wherein the coil impedance of the second coil is set so that a magnetic field of the second coil generated due to a magnetic field of the first coil reduces the magnetic field of the first coil at a location within the second coil by at least 20%.

- and
- a device for evaluating information about the magnetic field to obtain information about the position of the movable object in the goal area.
A method for determining information about a position of a movable object in a goal area in which at least two coils are attached in parallel to a goal area defined and bounded by a goal, wherein the first coil is attached in an area behind the goal and a second coil is attached closer to the goal than the first coil or identical to the goal, wherein the first coil and the second coil respectively comprise a coil impedance, wherein the coil impedance of the second coil is set so that a field of the second coil generated due to a magnetic field of the first coil reduces the magnetic field of the first coil at a location within the second coil by at least 20%, comprising:
- generating a magnetic alternating field using the first coil;
- providing information about the magnetic alternating field which the movable object experiences at the position in the goal area;
- evaluating the information about the magnetic alternating field to obtain information about the position of the movable object in the goal area.
A computer program embodied within a computer readable medium and having a program code for performing the method for determining information about a position of a movable object in a goal area in which at least two coils are attached in parallel to a goal area defined and bounded by a goal, wherein the first coil is attached in an area behind the goal and a second coil is attached closer to the goal than the first coil or identical to the goal, wherein the first coil and the second coil respectively comprise a coil impedance, wherein the coil impedance of the second coil is set so that a field of the second coil generated due to a magnetic field of the first coil reduces the magnetic field of the first coil at a location within the second coil by at least 20%, comprising:
- generating a magnetic alternating field using the first coil;
- providing information about the magnetic alternating field which the movable object experiences at the position in the goal area;
