A quantified symbol stream is sampled, using the quantified symbols prior to the current symbol, to generate a modeling value that characterizes the stream. The system stores a plurality of patient medical records on a medical information database via a medical information server connected to a network. The phase monitor and protection circuit ascertains and transmits generator rotational motion for use by the monitoring and control circuit in discerning the various operating conditions. The device includes a first optical-signal duplicating unit and an optical-signal selecting unit.
