A connection system has two connectors connected to each other by a plurality of differential signal pairs. The antenna is configured to receive the radio signal. The client product scans all frequencies at a predetermined interval for explicit information on regulation-conformant methods of operation, including frequencies and output power levels. In addition, less time and inventory are required, thereby reducing labor and expenses. Also, the interior volume of the crucible is made to have height to width ratio of 0. Position sensitive triggering of a laser can be used to generate laser beam pulses to melt and recrystallize semiconductor material at precise locations on the surface of the workpiece while it is translated on a motorized stage.
