    The system, except for the seismic controller, was designed in-house by Patrick Laplace as a light-weight, high-performance shake table primarily targeted for experiments involving vertical excitation including but not limited to seismic qualification testing. The table is comprised of a 10ft x 10ft (3m x 3m), 7-ton platen and can carry a
