  • Patent number: 12213089
    Abstract: A method and an apparatus for signal synchronization are disclosed. The method for signal synchronization includes: A self-synchronizing first terminal device broadcasts first synchronization information, determines whether the first terminal device and a second terminal device have implemented signal synchronization when receiving second synchronization information sent by the second terminal device, and determines, based on a determining result, whether to synchronize with the second terminal device. This reduces a probability of communication interruption caused by synchronization source switching by the first terminal device after the second terminal device performs synchronization by using the first terminal device as a synchronization source. The method for signal synchronization may be applied to scenarios such as the intelligent driving, intelligent connected vehicles, and internet of vehicles.

  • Patent number: 11664256
    Abstract: The application discloses a placement system for a door of a wafer pod, including a loadport. A docking interface is formed in the loadport, a placement mechanism is arranged on one side surface of the loadport, and includes a swing component, a follower component, and a docking plate. The swing component and the follower component are respectively connected to the docking plate, and the swing component can drive the docking plate to place the docking plate obliquely above the docking interface. By utilizing the space at the top of the loadport, the structural layout of the loadport is more reasonable; and the docking plate is placed nearly horizontally after the door is placed at a designated position, and provides a supporting force to the door, so that dependence on the vacuum suction is decreased, thereby avoiding the influences due to fluctuations of air pressure.
