Sensing of a magnetic target
The present invention relates to the sensing of a magnetic target. The apparatus (110) comprises a magnetic target (120) for generating a magnetic field that is uniform and concentric about a central axis of the target (120); an array (140) of three-axis digital magnetic compasses (210) for sensing...

| Zusammenfassung: | The present invention relates to the sensing of a magnetic target. The apparatus (110) comprises a magnetic target (120) for generating a magnetic field that is uniform and concentric about a central axis of the target (120); an array (140) of three-axis digital magnetic compasses (210) for sensing the magnetic field; and a processor for finding intersection points of vectors from the compasses to the target (120). The vectors lie in a global X-Y plane that is normal to the central axis. Each vector indicates a direction of sensed magnetic field from one of the compasses to the magnetic target (120).
本发明涉及磁性目标的感测，其中公开了种装置(110)包含：磁性目标(120)，用于产生均匀的并且关于该目标(120)的中心轴线同心的磁场；三轴数字磁性罗盘的阵列(130)，用于感测该磁场；以及处理器(140)，用于找到从罗盘(210)到目标(120)的矢量的交点。所述矢量位于垂直于中心轴线的全局X-Y平面中。每个矢量指示从罗盘(210)中的个到磁性目标(120)的被感测磁场的方向。 |
