Zusammenfassung: | Methods, apparatuses, and systems for detecting a stray magnetic field are provided. An example apparatus may include a first magnetic sensor element at a first position relative to a magnetic field source to detect a target magnetic field emitted by the magnetic field source, a second magnetic sensor element at a second position relative to the magnetic field source to detect the target magneticfield emitted by the magnetic field source, and a processor element electronically coupled to the first magnetic sensor element and the second magnetic sensor element. In some examples, the processorelement may be configured to: receive a first output from the first magnetic sensor element, receive a second output from the second magnetic sensor element, and detect the stray magnetic field interfering with the target magnetic field based at least in part on the first output and the second output.
本发明提供了用于检测杂散磁场的方法、装置和系统。示例性装置可包括第一磁性传感器元件、第二磁性传感器元件和处理器元件,该第一磁性传感器元件位于相对于磁场源的第一位置处,以检测由该磁场源发射的目标磁场;该第二磁性传感器元件位于相对于该磁场源的第二位置 |
