An internet based archive system for personal computers comprising a personal computer, an internet connection to an archive server, and an archive server. A reservoir tank with graduations thereon is provided with appropriate water lines for filling the reservoir tank with a desired amount of measured and tempered water. a component B with recesses and a component W with bumps. This change with time of the compression wave velocity andor the relative energy of the ultrasound waves andor the frequency spectra of the ultrasound waves is approximated through a compensating function, preferably the Boltzmann function. A reconfiguration device receives input from a user specifying the data pattern and action, processes the input to generate the configuration information necessary to reprogram the PLD, and transmits the configuration information to the packet processor for reprogramming thereof.
