Abstract: The present invention relates to an apparatus for water descaling. The system comprises hydrodynamic cavitation reactors with a cavitator selected from the group consisting of an orifice plate, venturi and a rotating cavitator, in combination with an infrared radiation emitter. Combination of hydrodynamic cavitation reactor with infrared radiation achieves effective salt precipitation from the hard water with reduced pressure drop and reduced number of recirculation, resulting in higher savings due to reduced energy costs.

Abstract: A user-friendly graphical user interface is proposed to enable creation of a playlist of data elements of any type. A graphical object is displayed representing a content based logical map arranged in two or three dimensions and defining characteristics at predefined coordinates. A trajectory defined by a mathematical spline function and having a start point, an end point and one or more intermediate points is drawn and can be changed by moving the steering point of at least one of the start point and the end point. The data elements for the playlist are selected by searching in meta-data for characteristics that best match the characteristics of points along the trajectory.

Abstract: The invention enables music tracks in a playlist to be explored using a unique music genogram data format. The invention further enables a user to map an emotional trajectory on the emotion wheel as a basis for the generation of the playlist with music tracks. The invention provides for a unique visualization of the playlist using the emotional wheel representation. A user will be given the option to specify an initial mood and a destination mood. The trajectory between the initial mood and the destination mood may be steered through the emotions falling in-between. The thus obtained mood trajectory is then populated by music tracks to form a playlist.

Abstract: A device for purifying water includes: a reactor housing having an inlet opening for supplying polluted water and an outlet opening for draining the purified water from the reactor housing; hydrodynamic cavitation means arranged in the reactor housing for causing cavitation in the polluted water; main light means for irradiating the polluted water with ultraviolet light, wherein the main light means provide a polychromatic and/or monochromatic pulsed ultraviolet light, which is synchronized selectively with the specific cavitation event(s) in the polluted water.
