柔性磁芯电子标记物
摘要：
本发明提供了用于标记不可见制品的电子标记物和制备电子标记物的方法。所述标记物包括由柔性且有时高磁导率的磁性材料制成的芯和围绕所述芯设置的螺线管。电容器与所述螺线管电耦合，并且所述标记物被调谐成响应于特征谐振频率下的信号。所述标记物可以被附接到内埋地下的导管。所述标记物还可以包括射频标识芯片。
摘要（英）：

An electronic marker and method of making an electronic marker for marking obscured articles. The marker includes a core made of flexible, and sometimes high permeability magnetic material and a solenoid disposed around the core. A capacitor is electrically coupled with the solenoid, and the marker is tuned to respond to a signal at a characteristic resonant frequency. The marker can attached to a conduit to be buried underground. The marker can further include a radio frequency identification chip.
