  • Publication number: 20240175324
    Abstract: The disclosure discloses a penetrating cushion damping device comprising a penetrator, and belongs to the field of in-situ penetrating exploration of extraterrestrial celestial bodies. A magnetic conductor encloses the non-penetrating end of the penetrator, a drag plate connected to the penetrator is provided at the lower end face of the magnetic conductor, and a magnetic source structure for generating magnetic force on the magnetic conductor is provided in the non-penetrating end of the penetrator. The disclosure utilizes the penetrating cushion anti-drag mode with the drag plate and the electromagnetic structure, which is self-adaptive to the flight penetration speed and compact in structure, reduces the jump probability, and further reduces the cushion resistance after the speed is reduced.

  • Patent number: 11581735
    Abstract: Provided are a method and apparatus for dynamically controlling electrical loads, a storage medium and an electronic apparatus. The method includes that: a current capacity balance of a user sub-region is acquired from an intelligent electricity monitoring and metering terminal through a mobile terminal; when the current capacity balance is smaller than a load power of an electric consumption device to be started in the user sub-region, a regional coordination control apparatus or a server is requested through the mobile terminal to adjust and increase a capacity allocated for the user sub-region, such that a capacity balance will be greater than or equal to the load power; and whether to allow to start the electric consumption device is determined according to a decision replied by the regional coordination control apparatus or the server.
