  • Publication number: 20250236454
    Abstract: An electrical control box for superconducting magnet transportation and a device for transporting a superconducting magnet, relating to the field of superconducting magnet transportation, are configured to transport the cryogenic superconducting magnet. The electrical control box for superconducting magnet transportation is provided to address the problem that rated load capacity requirement of the transport apparatus is too high while transporting the superconducting magnet. A function of one input to two outputs is implemented through a power supply distribution module to supply power to a helium compressor and a refrigerator respectively to align with the common practice of transport personnel. In addition, a delay module is arranged in a power supply output connected to the helium compressor to provide power to the helium compressor later than the refrigerator, i.e., the start-up of helium compressor and the refrigerator are asynchronous.

  • Patent number: 12276805
    Abstract: The present invention relates to a method and system for actively adjusting diopter of a head-mounted display, and a head-mounted display. The method includes the following steps: adjusting a relative distance between a displaying component of the head-mounted display and an optical component by a motor driving component; presetting a mapping relationship between a diopter value and a motor pulse number; accordingly converting into a control signal for the motor driving component according to the mapping relationship; and actively adjusting the relative distance between the displaying component of the head-mounted display and the optical component by the motor driving component according to the control signal. A target diopter value is inputted and converted into a corresponding control signal. The motor driving component actively adjusts the relative distance between the displaying component of the head-mounted display and the optical component according to the control signal.
