Claim:
1. A system for mitigating vibration of a mass, comprising: an elastic membrane enclosing at least one interior space and having an outer surface, an enclosing material to enclose the elastic membrane to limit a degree of expansion of the elastic membrane; a mass sensing device having a sensing surface for sensing a mass of the load, the mass sensing surface coupled between the load and the pallet; at least one port coupling the outer surface to the at least one interior space, wherein the at least one port provides a source of fluid ingress into the interior space and fluid egress out of the interior space; an electronic fluid pump having a nozzle coupled to the at least one port, the electronic fluid pump to modulate an amount of fluid in the interior space to adjust the packing density of granular material; and a computing device coupled to the mass sensing device and the electronic fluid pump, the computing device to receive an input from the mass sensing device and to drive a control input of the pump to regulate, in response to the input, the amount of fluid in the interior space; a granular material distributed within the at least one interior space, wherein the granular material includes a volume of free flowing macroparticles, the volume of free flowing macroparticles selected support the mass; wherein the computing device continuously receives input from the mass sensing device and, in response to a change in the relative mass of the load, automatically adjusts a packing density of the granular material between a first jammed state having a first packing density of granular materials and a second jammed state having a second packing density of granular materials to reduce vibration of the load.
