Abstract: The invention relates to a device comprising two table-like supporting plates, which serve as operating and functional units. The supporting plates each have a longitudinal and transversal extension, are arranged parallel to one another in a frame that can be immobilized in a fixed manner, and are each mounted so that they can spatially move with three-dimensional degrees of freedom that are independent of one another. In addition, a motor-operated drive is provided that can set the supporting plates in oscillatory motion at least in a one-dimensional direction and independent of one another.
