A system is provided that includes a base unit that is operable to transmit data wirelessly. Compression to two contacts breaks the breakable coating exposing an electrically conducting material which makes contact with the first and second contacts. When in the first state, the insulative materials may be processed or support layers or structures which are being processed. An activating lever is linked to the stabilizing bar to move the bar into the raised or the lowered position. Second, for the quality measurement, the tool processes the reconstructed data by critical bands, which can differ from the quantization bands used to compress the data.
