A new and distinct Echeveria cultivar named \u2018ECRAQ03-0\u2019 is disclosed, characterized by a non-branching rosulate plant form, long pink scape, unique leaf margin coloration and tight leaf edge undulations. To this end, an image filter is arranged in an intermediate focusing plane, and a matrix of microlenses is arranged at a distance from the image filter, with each microlens that is associated with an opening of the image filter. Clock signals are generated by a clock control circuit of the control circuit. The jet inhibits migration away from the suction surface of a clearance vortex formed by leakage of air over the tip of the rotor blade. The blocking portion moves slidably within an O-ring that prevents loss of pressure from the artificial airway system.
