  • Patent number: 10711427
    Abstract: A cavity-type load box includes an oil cavity unit. The oil cavity unit includes a sealing plate with a U-shaped section and two flat plates with edges wrapped in the sealing plate and is provided with an oil injection structure. Liquid oil injected from the oil injection structure flows into the oil cavity unit. The edges of the two flat plates are wrapped in the sealing plate with the U-shaped section, so that after the liquid oil enters an oil cavity via the oil injection structure, the sealing plate is stretched under the pressure of the liquid oil to cause deformation of the oil cavity. As a stress required for deformation of the sealing plate is very small, the pressure generated by the liquid oil directly acts on an object on the upper or lower surface of the cavity-type load box, and accordingly, the object s pushed.

  • Patent number: 10306073
    Abstract: A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.
