Abstract: The present invention relates to a wind apparatus to maximize the amount of kinetic energy associated with an air flow captured over time by said wind apparatus. In particular, said wind apparatus comprises at least one wind system, wherein said wind system comprises at least one a bladed device provided with one or more blades and configured to be electronically controlled so that its aerodynamic behaviour changes over time based on the action exerted by said air flow on said one or more blades of said bladed device.

Abstract: The present invention relates to a method for modifying at least one video frame of a digital video stream to be displayed on a display area. Each correction scheme has one or more specific digital filters based on visual defects perceived by a person with respect to a video frame portion, is configured when predetermined conditions are met and reconfigured whenever the origin position of an eye reference system associated with a respective eye is different from the position of the same origin in said predetermined conditions and/or the orientation of said eye reference system is different from the orientation of the same eye reference system in said predetermined conditions.
