Abstract: Systems, devices, and methods of protecting sensitive equipment against vibrations, mechanical shocks, and earthquakes. A support device includes a lower fixed or non-moving frame, and an upper movable frame. The two frames are connected via four dampers, at or near their four corners; and also by four generally-vertical cables or wires that together with the supported device operate as an inverted pendulum or an upside-down pendulum in response to incoming vibrations or applied forces. The dampers, as well as the inverted pendulum created by the cables, dissipate and absorb vibration energy and mechanical shocks. Optionally, the entirety of the support device has not more than four dampers. Optionally, the entirety of the support device has or not more than eight dampers, wherein four of the eight dampers are not connected to the vertical cables, and four other of the eight dampers are connected to lower ends of the four vertical cables.

Abstract: System, device, and method of reinforcement for raised-floors and for equipment thereon. A system includes a vertical support member to fixedly connect to a top-tier of a raised-floor and to a bottom-tier of the raised floor. The vertical support member includes an internal rod surrounded by an external pipe. The internal rod and the external pipe are connected via a top-side cap and a bottom-side cap. A modular-length slanted support member is further connected to the vertical support member. The slanted support member is fixedly connected to the bottom-tier of the raised floor, or to another, neighboring, vertical support member.
