摘要： In a method for detecting working states of I/O pins of electronic components, a signal is transmitted between at least two of the I/O pins. A probe of an oscilloscope is connected to an I/O pin. A waveform of the signal through the I/O pin is detected. Charges are transmitted to the probe. A working state of the I/O pin is determined by detecting whether the waveform of the signal through the I/O pin is changed when the charges are transmitted to the probe.

摘要： An electronic device includes a charging socket, a protection circuit, and a battery. The charging socket includes a charging pin. The charging pin is detachably connected to a charging plug of a power supply device, receives power from the power supply device, and transmits the power to the battery. The protection circuit is connected between the battery and the charging socket, and controls whether the battery is electrically connected to the charging pin. During a process of disconnecting the charging socket from the charging plug, the protection circuit disconnects the battery from the charging pin before the charging pin is disconnected from the charging plug.

摘要： A switching power supply includes an input terminal, a voltage converter, a feedback circuit, and a pulse width modulation (PWM) controller. The input terminal receives a first direct current (DC) voltage. The voltage converter transforms the first DC voltage into a second DC voltage and provides the second DC voltage to a load via transmission lines. The feedback circuit is configured for detecting voltage lost across the transmission lines. The PWM controller controls the voltage converter to adjust the second DC voltage according to the voltage loss.

摘要： An communication circuit of a communication device includes an interface unit, a direct current (DC) control circuit, a voice output circuit includes a voice input terminal, and a voice receiving circuit includes a voice output terminal. The interface unit outputs human speech and receives human speech from another communication device. The DC control circuit provides a constant current for the optocoupler circuit. When the outgoing human speech is coupled to the DC control circuit by a first optocoupler and sent to another communication device and incoming human speech is transmitted from the other communication device via the DC control circuit and a second optocoupler, echoes and extraneous noise in the speech is reduced.

摘要： A method for controlling an electronic device is provided. The electronic device has a child mode and an adult mode. The method includes capturing a touch image of a finger contacting with a touch screen when a touch operation is applied to unlock the touch screen. An area value of a touch image of the finger contacting with the touch screen is calculated based on the captured touch image and compared with one or more predefined area values. The user is determined to be a child or an adult according to the comparison result. The electronic device is controlled to alternatively enter the adult mode or the child mode based on the determination result.
