An anti-short-circuit detection apparatus includes a probe, a detection resistor, a switching circuit, and a detection circuit. The probe is disposed between a power port and a ground port. A first terminal of the detection resistor is electrically coupled to a power circuit of the user terminal, and a second terminal of the detection resistor is electrically coupled to the probe. The switching circuit is electrically coupled to the first terminal of the detection resistor and a processor of the user terminal and is configured to perform switching to be grounded or ungrounded under the control of the processor. The detection circuit is electrically coupled to two terminals of the detection resistor and the processor, and is configured to trigger the processor to control the user terminal to issue a short-circuit warning or turn off the power circuit when the short-circuit current is not zero.

Embodiments disclose a blood pressure parameter detection method. The method includes: detecting, by user equipment UE, an electrocardiogram ECG signal of a user by using a first ECG contact and a second ECG contact that are connected to an ECG detection circuit of the UE; when determining that the detected ECG signal matches a pre-stored reference ECG signal, enabling, by the UE, a photoplethysmogram PPG detection circuit, and detecting a PPG signal of the user by using a PPG detection point connected to the PPG detection circuit; and when determining that the detected PPG signal matches a pre-stored reference PPG signal, enabling, by the UE, a blood pressure detection application, and processing the detected ECG signal and the detected PPG signal by using the blood pressure detection application to obtain a blood pressure parameter of the user.

Blood pressure parameter detection method and user equipment

A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program.

The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program. It can be learnt from above that, the terminal can determine, according to a variation in light intensities, whether the terminal is blocked by clothes, and close the target program. This reduces running power consumption of the terminal and increases a standby time of the terminal.

Embodiments of the present invention a power supply circuit of a power amplifier and a terminal, relating to the communication field. The power supply circuit of the power amplifier includes a direct current/direct current converter chip, where the direct current/direct current converter chip includes an input pin, an inductance pin, and a feedback pin, and the input pin is connected to a power supply and the inductance pin is connected to a voltage input end of the power amplifier through an LC storage circuit.
