e command says "no" (disabling of/ban on action), all SFU would be inactive and no result of action produced. In the presence of external influence and if the command says "yes" (permission for action), all SFU would be active and the result of action produced. The "capacity" of the composite SFU is 4 times higher than the "capacity" of simple SFU. SFU is activated through the inputs of command of their control blocks. Every simple SFU has its own DPC and DPC common for all of them. Uncontrollable and controllable SFU may be used to build other (Composite) SFU, more powerful than single SFU. In the real world there are few simple SFU which bring about minimal indivisible result of action. There are a lot more of composite SFU. For instance, the cartridge filled with grains of gunpowder is a constituent part of SFU (SFU for a shot), but its explosion energy is much higher that that of single grain of gunpowder. The composite SFU flow diagram is very similar to that of simple SFU. It is only quantity variance that stipulates the difference between the composite and simple SFU. Simple SFU contains only one SFU, just SFU itself, whereas the composite SFU contains several SFU, so there is a possibility of strengthening of the result of action. Thus, simple and composite SFU contain two types of elements: executive elements (effectors performing specific actions for the achievement of the system's preset ovearll goal) and the elements of management (block) (DPC, the analyzer-informant and the stimulator activating SFU). Composite SFU has the same control block as the separate SFU, i.e. the elementary one with direct positive (guiding) connection (DPC). Composite SFU perform based on the "all-or-none" principle, too, i.e. they either produce maximal result of action in response to external influence or wait for this external influence and do not perform any actions. Composite SFU only differ from simple SFU in the force or amplitude of reaction which is proportional to the number of simple SFU. If the domino dices are placed in a sequential row the result of their action would be the lasting sound of the falling dices which duration would be equal to the sum of series of drops of every dice (Extension of duration of the result of action). If the domino dices are placed in a parallel row the result of their action would be the short, but loud sound equal to the total sound volume resulting from the drop of each separate dice (capacity extension). The performance cycle of an ideal simple and composite SFU is formed by micro cycles: perception and selection of external influence by the "X" receptor and decision-making; influence on the executive elements (SFU); response/operation of executive elements (SFU); function termination. The "X" receptor starts to operate following the onset of external influence (the 1 st micro cycle). Subsequently some time would be spent for the decision-making, since this decision itself is ...
