The present invention discloses a nano-cluster that includes a plurality of nano-particles, wherein the nano-particles can disperse in response to an environmental cue. At least one brake element is automatically activated by applying a predetermined brake force, and a predetermined decision torque level is applied to the rotation component by means of the power source, wherein the decision torque level is indicative for the braking capacity of said at least one brake element when said predetermined brake, force is applied. The hydraulic continuously variable transmission includes a fixed-displacement swash plate plunger pump and a variable displacement swash plate plunger motor, which are connected through a closed hydraulic circuit. An assembly drawing of the blood circuit obtained by combining the selected unit components, a full length and an amount of filled blood are displayed on a display by using the database.
