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: This application provides a downlink transmitting system and a switching method. The downlink transmitting system includes at least one digital intermediate frequency module group, at least one Tx port group, a plurality of PAs, at least one switching switch, and an antenna array. The plurality of PAs are connected to the antenna array. The plurality of PAs are connected to all Tx ports included in the downlink transmitting system in a one-to-one correspondence. The at least one digital intermediate frequency module group is in a one-to-one correspondence with the at least one Tx port group. Each Tx port group is connected to each digital intermediate frequency module in a corresponding digital intermediate frequency module group through one switching switch. Each Tx port group includes a plurality of Tx ports.

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.
