Abstract: Disclosed is a method for selecting a cosmetic product, and a method for image acquisition and image processing for the selection method, including: acquiring an image of a person in a controlled lighting environment, and measuring and recording the colorimetric coordinates of the person's face; processing the image to determine an absolute value of the skin tone; correlating the absolute value with a usage color map established for each of multiple cosmetic products of a database by measuring the color of each cosmetic product under its conditions of use, and to determine a personalized color matrix; extracting, from the database, the cosmetic product(s) whose color measurement is part of the personalized color matrix; using an information medium, presenting the product(s) included in the personalized color matrix; and optionally selecting the preferred product(s) chosen by the person from those that are part of the personalized color matrix.

Abstract: A transparent article having a face provided with a nano structure, wherein a top part of the nano structure has hydrophobic properties and a remaining part of the nanostructure confers antifog properties to said face of said transparent article.

Abstract: An article having a nanotextured surface with hydrophobic properties, said nanotextured surface comprising an array of pillars (71) defined by a surface fraction (?s) of the pillars, a pitch (P) of the pillars and an aspect ratio (H/2R) of the pillars, wherein: —the surface fraction (s) is equal or greater to 2% and equal or less to 80%; —the pitch (P) is equal or less to 250; —the aspect ratio (H/2R) is equal or less to 2.4, where H is the height of the pillars and R is the radius of the pillars; —the pitch (P), the height (H), the radius (R) are expressed in nanometers (nm); —the nanotextured surface comprises at least partially a hydrophobic material.

Abstract: A thin soft magnetic film combines a high magnetization with an insulating character. The film is formed by nitriding Fe-rich ferromagnetic nanograins immersed in an amorphous substrate. A selective oxidation of the amorphous substrate is then performed. The result is a thin, insulating, soft magnetic film of high magnetization. Many types of integrated circuits can be made which include a component using a membrane incorporating the above-mentioned thin film.

Abstract: A radiofrequency device may include an electrically conducting element associated with at least one continuous magnetic element. The first continuous magnetic element may include a substrate coated with a magnetic film having a granular structure, with grains that are inclined to the normal to the substrate, or a columnar texture inclined to the normal of the substrate.
