Abstract: The invention relates to a method for analysis of magnetic fields or signals used for the determination of the position of an object, wherein two temporally to each other shifted magnetic signals or fields are generated by two conductors arranged at least in part or completely separated from each other. The magnetic fields generated by the conductors are consecutively being captured by at least one and preferably three sensors arranged orthogonally to each other and determining from the captured signals information for determining the position of the object carrying the sensors relative to the conductors.

Abstract: A method for deciding whether a movable object has been brought through a goal having a goal area defined by the goal, an internal magnetic field being measurable, within the goal area or in parallel with the goal area, which is larger than an external magnetic field present outside the goal area, the method including a step of generating the internal magnetic field within the goal, a step of providing information about a magnetic field experienced by the movable object, and a step of evaluating the information about the magnetic field to provide a goal statement by means of a detection that the movable object has passed through the internal magnetic field.

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%.
