Abstract: A graceful shutdown of a computer system is initiated by sending a command to an asynchronous dynamic random access memory refresh (ADR) trigger device to assert an ADR trigger. Responsive to the command, the ADR trigger device asserts the ADR trigger to initiate an ADR of a non-volatile dual in-line memory module (NVDIMM) of the computer system. In response to the ADR trigger being asserted by the ADR trigger device, an ADR of the NVDIMM is performed before completing the graceful shutdown of the computer.

Abstract: A variable damping shock absorber has a sleeve and a piston rod, one end of the sleeve being an opening and the other end being closed, one end of the piston rod being inserted through the opening and slidable in an axial direction inside the sleeve. Two sets of friction plates are arranged in the axial direction between an inner wall of the sleeve and an outer wall of the piston rod. A friction plate is fixed in the axial direction with the inner wall of the sleeve, and a sliding friction force between each friction plate set and the outer wall of the piston rod gradually decreases from the closed end to the opening end of the sleeve. The structure can ensure that the damping force is variable under different load and rotational speed conditions.
