Abstract: The present disclosure relates to example terminal unlocking methods. One example method includes controlling, by at least one processor of a terminal using an analog front end (AFE), a transmit electrode of the terminal to send a bioelectric current. A communications connection is established between the terminal and a band when a receive electrode receives the bioelectric current. The terminal then receives an unlocking password sent by the band and performs unlocking according to the unlocking password.

Abstract: The present disclosure relates to a system for determining a location of an in-water object. The system includes a first wearable device and at least three sensors. Each sensor is placed in water, and is configured to emit an electrical signal. The first wearable device is located on a to-be-located object, the to-be-located object is placed in the water, and the first wearable device is configured to: separately determine received signal strength indicator RSSI values of received electrical signals emitted by the at least three sensors, determine a distance between the first wearable device and each sensor according to the determined RSSI value, determine a location of the first wearable device in the water according to a pre-measured location of each sensor and the determined distance between the first wearable device and each sensor, and use the location as a location of the to-be-located object in the water.

Abstract: The present disclosure relates to a power management circuit including a control circuit, a first switch module, a second switch module, and a voltage conversion circuit. A first input end of the control circuit receives a main battery activeness detection signal, a first output end is connected to an enabling end of the second switch module which is connected to the voltage conversion circuit and an energy recovery component, and a second output end is connected to an enabling end of the first switch module which is connected to the voltage conversion circuit, a secondary battery, and a main battery. According to the received activeness detection signal, a channel used by the energy recovery component to charge the secondary battery is connected, or a channel used by the secondary battery or the energy recovery component to charge the main battery is connected.

Abstract: The present disclosure relates to a wearable device and a wearable device charging method. The device includes a connector, a charging module, and a battery. The connector includes a first input end, a second input end, a first output end, and a second output end. The first input end is configured to receive a current signal, and the second input end is configured to receive a voltage signal. The first output end is connected to the charging module, and the charging module and the second output end are connected to the battery. The connector determines, according to the voltage signal of the second input end, whether the current signal is to be transmitted by the first output end or to be transmitted by the second output end to cause the wearable device to charge the battery according to the current signal directly or by the charging module.
