    • A detection system determines the position of an object moving along a first direction. The system includes a magnetic field source generating a magnetic field signal and a magnetic field detection system coupled to the object. The detection system includes a source interface module with magnetic field sensors positioned a known distance apart along a second direction different from the first direction. Each sensor detects the magnetic field generated by the magnetic field source and generates a magnetic field signal. A processing module processes the magnetic field intensity signal produced by the source interface module. The processing module generates data for each sensor in the source interface module, which is made up of points representing peak magnetic field and sensor location along the second direction. The points are compared to determine the distance of the object from the magnetic field source along the second direction.
    • 检测系统确定沿着第一方向移动的对象的位置。 该系统包括产生磁场信号的磁场源和耦合到该物体的磁场检测系统。 检测系统包括源接口模块,其具有沿着不同于第一方向的第二方向定位成已知距离的磁场传感器。 每个传感器检测由磁场源产生的磁场并产生磁场信号。 处理模块处理由源接口模块产生的磁场强度信号。 处理模块为源接口模块中的每个传感器生成数据,该数据由表示峰值磁场和沿着第二方向的传感器位置的点组成。 比较点以确定物体沿着第二方向与磁场源的距离。
