Abstract: A first-order resistor-inductor (RL) circuit is allowed to alternate a direct-current excitation response and a zero-input response so that a direct-current magnetic field generated by an inductor magnetizing coil changes alternately in magnetic field intensity with a change in magnitude of current. After a testing object is placed in the direct-current magnetic field changing alternately in magnetic field intensity, the testing object is magnetized and also causes a change in inductance of the magnetic field. Whether a change occurs in electromagnetic properties of the testing object can be determined and detected by detecting the inductance change of the magnetizing coil or detecting electrical characteristic change caused by the inductance change of the magnetizing coil, thereby determining whether quality defects such as steel wire cracks and wire breakage in a steel wire rope occur. Alternatively, the properties such as a sectional area or a zinc layer thickness can be analyzed.

Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.
