Plankton....RE: image noted, that would be "fig.1" unchanged..of the patent. Where item 21(micro-controller) as a whole, stays intact....as further referenced on page one of the patent.

Reference page one ..along with "fig.1' for a complete picture of what item 21 is.

Item 21 represents micro controller(21) and control circuitry(21) as a complete Processor concept....tied to the as needed distributive device power-source.
