A production line for carrying out machining and cleaning operations on rectangular frameworks, is provided. A handheld device is capable of communicating with the data processing apparatus. One end of the flexible printed circuit board has plurality of feeder wires that connect to one of the terminal lands of each of the recording elements. An extension of the actuation sleeve over the atraumatic forceps jaws proximal ends may be configured to gradually close the atraumatic forceps jaws wherein the atraumatic forceps jaws initially contact at the atraumatic forceps jaws distal ends. The cMUT allows variable operation voltage by requiring only one AC component. The conductive line includes a conductive layer and a barrier layer separating the conductive layer from a portion of the semiconductor device.
