  • Patent number: 12241174
    Abstract: A method used to repair a workpiece through a combination of laser and an electrochemical reaction is provided. A tool anode is arranged on the back side of the workpiece and is spaced therefrom. A laser beam is focused on an outer surface of the workpiece to realize localized repairing on the back side. The method realizes localized coating repairing on the back side of the workpiece through coordination between the thermal effect of the laser and the electrochemical deposition based on the characteristic of high thermal conductivity of the workpiece. The electrodeposition reaction does not occur in regions that do not need to be repaired. The operating process is simple, the cost of the plating solution is largely reduced, and the problem that the coating on the inner wall of the thin-walled workpiece is difficult to repair due to stripping is solved.

  • Patent number: 12073243
    Abstract: Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.
