There is disclosed a process for purifying a natural product using a two-phase, multi-solvent system followed by vacuum concentration and back extraction. The method and system include a wireless transceiver for automatically and adaptively controlling wireless transmissions using a Waveform-DNA method. The pair of fin-shaped bumps are electrically connected to form an inter-board connection terminal. A timer in, or coupled to, the controller alters the control signal to open the controllable switch if the liquid level in the sump remains above the selected level for a preselected time period. An arming switch is configured to initiate arming when a predetermined condition in the combined signal is detected, such as the presence of a frequency in the combined signal at the difference between the frequencies of the individual signals from the logic elements.
