  • Patent number: 10081266
    Abstract: Embodiments of the present invention provide a measuring device with a receiver coil array and evaluator. The receiver coil array is configured to detect three magnetic field components of a magnetic field of a conductor loop array generated by an electric alternating current signal and to provide a magnetic field component signal for each of the detected three magnetic field components. The evaluator is configured to evaluate the magnetic field component signals in order to determine the phase relation to the electric alternating current signal allocated for the magnetic field component signals, wherein the phase relations each include coarse position information of the conductor loop array relative to the conductor loop array and wherein the evaluator is configured to determine a resulting intersection of the coarse position information, wherein the resulting intersection includes or results in fine position information of the receiver coil array relative to the conductor loop array.

  • Patent number: 9795829
    Abstract: Embodiments relate to a concept for determining a transit of a movable object through a detection area within a detection plane. At least one exciter antenna provides an exciting electromagnetic field. The exciting electromagnetic field or at least one spatial component thereof has a field strength above a field strength threshold in the detection area. The exciting electromagnetic field is capable of exciting the movable object to emit an electromagnetic response signal comprising information on a position of the movable object. At least one sensor antenna comprising a magnetic core receives the electromagnetic response signal. The at least one magnetic core is positioned in a region of the exciting electromagnetic field where the field strength of the exciting electromagnetic field or the at least one spatial component thereof is below the field strength threshold.
