Abstract: This application provides a method for identifying a terminal device and a communications apparatus. A core network element obtains classification information for classifying a terminal device, and then determines, based on the classification information and a parameter of a first terminal device, a type of the first terminal device, to identify the first terminal device. In this process, the core network element identifies the first terminal device in a supervision area by using the classification information and the parameter of the first terminal device, to identify a terminal device that is not registered in a supervision system, thereby improving security of the terminal device.

Abstract: A sliding sheet includes a fabric layer is disclosed. The fabric layer includes warp yarns and weft yarns. The warp yarns are interlaced with the weft yarns. The sliding sheet has a first edge extending in a length direction of the sliding sheet. The warp yarns are bent toward a middle portion of the first edge. A method for manufacturing the sliding sheet is also disclosed. An auxiliary yarn is woven with the warp yarns and the weft yarns to form a fabric raw layer. A tension for weaving the auxiliary yarn is adjusted so that the tension of the auxiliary yarn is greater than the tension of the warp yarns, thereby bending the warp yarns in the fabric raw layer toward the auxiliary yarn. The fabric raw layer is heated to fix the shape of yarns, and cut into the fabric layer to form the sliding sheet.

Abstract: A power inverter includes primary switches, a transformer, a rectifier, a high voltage (HV) bus, an H-bridge, a detector, and a feedback controller. The transformer receives a switched direct current (DC) signal from a battery. The H-bridge outputs an AC signal to a stepped load. The detector detects a step-up load change by monitoring the stepped load. The feedback controller regulates a duty cycle of the AC signal, thereby reducing total harmonic distortion (THD) affecting the power inverter and the stepped load. The feedback controller further regulates the duty cycle of the AC signal by temporarily setting the primary switching duty cycle at a maximum allowable level in response to the step-up load change.
