Abstract:
1. A system for controlling motion, the system comprising: a stage having four corners, a generally planar upper surface, front and rear edges resiliently supported for generally rectilinear movement of the upper surface along a motion control axis lying in the plane of the upper surface and perpendicular to the front and rear edges of the stage, and opposite side edges, each having a laterally extending wing formed thereon and defining a cutout at each of the four corners of the stage; and, a snubber assembly surrounding the periphery of the stage and having four mesas formed thereon, each of the mesas extending generally perpendicular to the plane of the upper surface of the stage and into a corresponding one of the cutouts of the stage and being configured to cooperate with adjacent edges of the stage and the wings so as to limit movement of the upper surface of the stage to substantially rectilinear movement along the motion control axis.
