An apparatus has a pump module providing pump energy, a resonator and a controller. The roller includes a generally elongated substantially cylindrical tube. The tibial component includes a Morse taper cavity on one piece of the tibial component and a Morse taper extension on another member of the component for receipt therein. To assure that the residual static electricity is discharged completely, the length of time t1 is determined to meet the size of the cathode-ray tube. In various exemplary embodiments, substrates of varying sizes and types can be registered into common sets using the systems and methods of this invention. In addition, since the sound generator according to the present invention does not access a parameter memory when downloading, previously processed data is not erroneously handled, and there is no need to rewrite new data to an internal memory after the download operation is completed.
