Abstract
An isolation system includes a housing that contains an electromagnet, a sensor and a controller. The housing is mounted underneath a table top of an isolation table (or other structure requiring isolation from a second body), and target elements, such as permanent magnets, are associated with the frame of the table in proximity to the housing. The sensor provides an input signal representative of motion of the table to the controller, which generates a control signal for the electromagnet to produce a force acting on the target element. The housing can be attached to the table top with magnets, which facilitate installation. The housing provides a unit that is simple to install, is unobtrusive, and advantageous for retrofitting existing isolation tables.
