    • An exemplary earphone detecting circuit includes a signal input terminal, a voltage dividing circuit, a detecting circuit, and a signal output terminal connected electronically in that order. The signal input terminal is connected to an earphone jack of a portable electronic device. The signal output terminal is connected to a microcontroller of the portable electronic device. When the portable electronic device receives a call, the signal input terminal receives a signal and transmits the received signal to the detecting circuit through the voltage dividing circuit, the detecting circuit processes the signal transmitted to the signal output terminal to be constant.
    • 示例性的耳机检测电路包括以该顺序电连接的信号输入端子,分压电路,检测电路和信号输出端子。 信号输入端子连接到便携式电子设备的耳机插孔。 信号输出端子连接到便携式电子装置的微控制器。 当便携式电子设备接收到呼叫时,信号输入端接收信号,并通过分压电路将接收到的信号发送到检测电路,检测电路将传输到信号输出端的信号处理为恒定。

    • In a near-field communication (NFC) service protection method of the mobile device, the mobile device includes an NFC controller, one or more security elements, a global positioning system (GPS) and a storage system. The method sets a security code for an NFC service of each of the security elements according to the geographic location of the mobile device as acquired by the GPS, and stores a security protection of the NFC service corresponding to each of the NFC services into the storage system. After an NFC service is selected from one of the security elements, and the NFC service is performed by executing an NFC application corresponding to the NFC service through the NFC controller. In addition, the method deletes the security code of the NFC service to disable the security protection of the NFC service when the NFC service needs to disable the security protection.
    • 在移动设备的近场通信(NFC)服务保护方法中,移动设备包括NFC控制器,一个或多个安全元件,全球定位系统(GPS)和存储系统。 该方法根据由GPS获取的移动设备的地理位置,为每个安全元件的NFC服务设置安全代码,并将对应于每个NFC服务的NFC服务的安全保护存储到存储器中 系统。 在从安全元件之一选择NFC服务之后,并且通过经由NFC控制器执行与NFC服务相对应的NFC应用来执行NFC服务。 此外,当NFC服务需要禁用安全保护时,该方法删除NFC服务的安全代码以禁用NFC服务的安全保护。
