A floating floor assembled from an array of interconnected subunits, each of which includes a stone, ceramic or porcelain tile and a one-piece polymeric plastic substrate to which the stone, ceramic, or porcelain tile is bonded. The method and apparatus allow a simultaneous quantitative and objective assessment of the strength of the muscular contraction through the use of a pressure sensor, without interfering on or modifying the conventional manual muscle test. The bottom surface is sloped downward from the inner edge to the outer edge. The outer jacket layer is applied by pressure extrusion, such that the spaces in the layer are almost filled by the material of the outer jacket layer, and the layer adheres to the inner sheath layer. The linkage moves the pedestal transversely through the load lock support surface opening to pick up the work piece from the support surface prior to treatment. The system and method includes an image management engine and graphical user interface that allows a user to manage, manipulate, edit and store the images in the electronic device.
