Automatic determination of the position of an object

Abstract

The disclosure 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.

What is claimed is: 
     
         1 . A goal of a sports field having two posts and a crossbar, wherein:
 the posts and the crossbar are composed of electrical conductive material;   the posts extend essentially at least to the surface of the sports field;   a conductor loop which encompasses at least a part of the goal of the sports field, the conductor loop being punctuated by at least one electrical non-conductive element.   
     
     
         2 . The goal of a sports field according to  claim 1 , wherein the conductor loop encompasses and is composed of the posts, the crossbar and at least a part of the sports field arranged between the posts and wherein the at least one non-conductive element is part of the goal of a sports field, the at least one non-conductive element being a connecting element arranged in between one post and the crossbar or an element which is dividing a post or the crossbar. 
     
     
         3 . The goal of a sports field according to  claim 1 , wherein the at least one non-conductive element is part of the sports field, which is arranged in an area of the sports field adjacent to a post and in particular a bracket of the post. 
     
     
         4 . The goal of a sports field according to  claim 1 , wherein the goal within the area of the conductor loop is in part, specifically predominantly, made of at least one conductive material and at least one non-conductive material. 
     
     
         5 . A sports field goal comprising:
 at least two posts extending to at least a surface of a field;   a crossbar coupled to the at least two posts;   wherein the at least two posts and the crossbar are made of electrical conductive material; and   a conductor loop which encompasses at least a part of the sports field goal, the conductor loop being punctuated by at least one electrical non-conductive element.   
     
     
         6 . The sports field goal according to  claim 5 , wherein the conductor loop comprises conductive soil. 
     
     
         7 . The sports field goal according to  claim 5 , wherein the conductor loop comprises a bracket extending retral from the sports field goal. 
     
     
         8 . The sports field goal according to  claim 5 , wherein the conductive loop comprises circular bearings of mesh extending backwards. 
     
     
         9 . The sports field goal according to  claim 5 , wherein the at least one electrical non-conductive element is made of plastic. 
     
     
         10 . The sports field goal according to  claim 5 , wherein the at least one electrical non-conductive element is made of a non-conductive fiber composite material. 
     
     
         11 . The sports field goal according to  claim 5 , wherein the at least two posts and cross bar are made of aluminum. 
     
     
         12 . The sports field goal according to  claim 5 , wherein the at least one electrical non-conductive element is made of a non-conductive fiber composite material.
