A communications system connected via a bus capable of transmitting multiplexed packets of control signals and AV signals while providing an environment, which is the same as an environment where connections are made using analog signal lines. The microstimulator forms a hermetically sealed structure. The structure can be used to create a field effect transistor. The plurality of piggyback substrates are processed, while attached to the carrier wafer, to produce a plurality of integrated circuit devices. The socket defined at the free end of the second end portion of the capstan is axially aligned with the longitudinal axis of the capstan. One of a plurality of management tools is launched to perform a selected one of the management tasks for the workstation.
