Abstract: A substantially spherical multi-blade wind turbine (SSMBWT) includes: (a) a plurality of multifunctional blades (2); and (b) a rotating axis (3) configured to rotate when the blades capture wind and for coupling to a power generator (4a), wherein each multifunctional blade (2) comprises three integrated functional sections (2a, 2b, 2c), wherein each functional section has a different shape and is configured to guide and evacuate incoming airflow and to capture wind energy from different anisotropic directions, ranging from around to above and below the body of the substantially spherical multi-blade wind turbine (SSMBWT).

Abstract: A multilevel semiotic and fuzzy logic user and metadata interface means includes: an interactive user interface means comprising at least one multilevel semiotic means addressable by a user and a fuzzy logic descriptor set module for storing multiple fuzzy logic descriptor sets; a metadata layer for linking said multilevel semiotic means to interactivity points present in content of the multimedia representation and defined by the metadata layer such that each level of each of the multilevel semiotic means identifies an interactivity point in the content and allows by selection of the interactivity point to perform a selectively varying content manipulation and to receive a resulting interactive presentation of content according to the selection: and a user control device for addressing the multilevel semiotic means.
