    • An integrated system of sensors that can be used to detect a direction of an externally applied magnetic field is disclosed. In one embodiment, the system can be incorporated into a compact package that can be used within an electronic device. A processor can use signals provided by the sensor system to provide an indication of the direction of the externally applied magnetic field. In one embodiment, the sensors can take the form of analog sensors such as Hall Effect sensors configured in such a way that the direction of the externally applied magnetic field can be deduced based in part upon detection signals provided by the Hall Effect sensors. In one embodiment, the Hall Effect sensors can be stacked one atop the other in such a way that relative signal strength of the detection signals from the sensors can indicate the direction of the externally applied magnetic field.
    • 公开了一种可用于检测外部施加磁场方向的传感器集成系统。 在一个实施例中,该系统可以被并入可以在电子设备内使用的紧凑型封装中。 处理器可以使用由传感器系统提供的信号来提供外部施加的磁场的方向的指示。 在一个实施例中,传感器可以采取模拟传感器的形式,例如霍尔效应传感器的配置,使得可以部分地基于由霍尔效应传感器提供的检测信号来推导外部施加的磁场的方向。 在一个实施例中,霍尔效应传感器可以以这样的方式堆叠在一起,使得来自传感器的检测信号的相对信号强度可以指示外部施加的磁场的方向。
