Abstract (en)
[origin: WO2008119479A1] In order to determine a position of a mobile object relative to a surface within a movement range that comprises a ground which the surface intersects along a line of intersection, a magnetic field of a first elongate magnetic field-generating object which is located at a first distance from the line of intersection is measured, and a magnetic field of a second elongate magnetic field-generating object that is located in or on the ground, at a second distance on another side of the line of intersection, is measured. Based on a comparison between the measured magnetic fields, it is determined whether the mobile object is located in front of or behind the surface. A generator that triggers the magnetic field-generating objects in a multiplex mode is provided for distinguishing which magnetic field-generating object generates which magnetic field. The magnetic field-generating objects can comprise forward conductors of a conductor loop, oppositely wound coils, or forward/return conductor combinations having a magnetically shielded return conductor.
