Abstract: Disclosed are a rotating shaft mechanism and a foldable mobile terminal. The rotating shaft mechanism provided in the embodiments of this application is mainly applied to a foldable mobile terminal, so as to implement unfolding and folding of two main body parts of the foldable mobile terminal. When the elastic support member is in a compressed state, at least some segments of the first part and the second part overlap in a floating direction, and the second part provides a compressed deformation space for a part or all of the first part. In this way, a height of the elastic support member in overall compression and deformation is reduced, and an ultra-thin design requirement of the foldable mobile terminal is met.

Abstract: This application provides a folding assembly and a foldable electronic device. The folding assembly is applied to a foldable electronic device, and is configured to carry a flexible display screen. The folding assembly includes a shaft base, a first housing, and a second housing. The first housing and the second housing are respectively disposed on both sides of the shaft base. A door plate swing arm is located above the shaft base and is disposed on each of both sides of a center line of the shaft base, one end of each door plate swing arm is rotatably connected to the shaft base, and the other end of each door plate swing arm is rotatably connected to the first housing or the second housing.

Abstract: A sampling assembly and a sampling method are provided. A self-calibration unit controls a first switch to be turned on, to enable a first sampling signal to be input to a sampling unit. The sampling unit processes the first sampling signal to obtain a second sampling signal, and outputs the second sampling signal to the self-calibration unit. The self-calibration unit controls the first switch to be turned off, controls a second switch to be turned on, and outputs a first calibration signal to the sampling unit. The sampling unit processes the first calibration signal to obtain a second calibration signal, and outputs the second calibration signal to the self-calibration unit. The self-calibration unit determines an error signal based on the first calibration signal and the second calibration signal. The self-calibration unit obtains a calibrated third sampling signal based on the second sampling signal and the error signal.

Abstract: A security control method for a social network user, a social application device and a terminal are provided. The method includes: when information is exchanged between users, a local-end social application acquires the security control authority of a local-end user set by an opposite-end user, and the local-end social application controls, according to the security control authority of the local-end user, the copying operation and the screen capturing operation of the local-end user on the information exchanged.

Abstract: A power sourcing equipment (PSE) chip, and a Power over Ethernet (PoE) device and method are provided, which can determine a status that a peer end is connected to a powered device (PD) when four cable pairs are used to supply power. The PSE chip includes a channel controller, a first channel detector, and a second channel detector. The channel controller sends detection voltages along a first and a second groups of cable pairs in an Ethernet twisted pair; determines a first impedance and a second impedance according to the detection voltages and corresponding currents that are detected; and determines that a first group or a second group of cable pairs is connected to a valid PD according to the impedances and a preset range.
