A method and system for processing a silicon thin film sample on a substrate. A portion of one of the conduits is equipped with a system for detecting the presence of the biofilm on the surfaces of the portion itself. The reflective screen may be embodied by at least one layer of metallic material with a thickness of the order of 500 \u212b to 2000 \u212b. The receiving station may also determine which of the plurality of MPDUs were successfully or not successfully received from the transmitting station. The stent can be detached by injecting a pressurized fluid through the channel of the probe thereby forcing the distal end of the stent to pop off. The X table moves back and forth in parallel with the rows of cylinder bores.
