摘要： A method for measuring the optical quality of a delineated region of a glazing, the delineated region being intended to be placed in front of an acquiring or measuring device such as a camera. The method is particularly suitable for measuring the optical quality of a delineated region of a transportation-vehicle glazing, such as an airplane or automobile windshield, in front of which an optical device for recording images or a device for measuring the environment outside the vehicle is placed with a view to enabling operation of an advanced driver-assistance system of the vehicle.

摘要： A method for driving an electro-optical functional layer by a control, the functional layer being applied on a substrate and being variable in its transmissive and/or reflective properties by applying an electric field, the control unit having a supply voltage input and a feed output, and a voltage measuring system and an energy store, includes measuring a voltage actually available at the supply voltage input, if the available voltage is greater than a reference value, driving the functional layer with an AC voltage via the feed output, the energy store being charged at least in sections, if the available voltage is less than or equal to a reference value, driving the functional layer with a DC voltage via the feed output. At least part of the energy for the driving is drawn from the energy store. The DC voltage is less than the peak value of the AC voltage.

摘要： A laminated glazing unit includes at least one first sheet of glass and one second sheet of glass glued to one another via a first adhesive interlayer, the first sheet of glass being intended to constitute the surface of the laminated glazing unit in contact with the outside atmosphere, in which the laminated glazing unit further includes, between the first sheet of glass and the second sheet of glass, an LOC (Localizer) antenna receiving between 100 and 120 MHz and a GLIDE (Slope) antenna receiving between 320 and 340 MHz, each antenna having dimensions that are sufficiently small not to hamper the vision, even to be practically invisible through the laminated glazing unit.

摘要： A method for separating a laminated glass panel including a film and at least two glass sheets, with the film being interposed between the two glass sheets, the method including weakening the mechanical properties of the panel using the energy of a laser beam along a predetermined separation line, by guiding the laser beam along the separation line, the separation line separating the panel into at least two pieces, wherein a laser device is used to provide the laser beam, the laser device providing a Bessel laser beam with a wavelength to which the glass sheets and the interlayer are transparent, wherein the length of the laser beam is at least equal to 80% of the thickness of the panel and the ratio of the scanning speed to the operating frequency is a value between two and seven times the diameter of the central lobe of the Bessel beam.

摘要： A projection assembly for a head-up display (HUD) includes a windshield, including an outer and inner pane joined to one another via a thermoplastic intermediate layer, and having an HUD region; and a projector directed at the HUD region. The radiation of the projector is predominantly p-polarised, and the windshield is provided with a reflective coating, which is suitable for reflecting p-polarised radiation. The reflective coating has exactly one electrically conductive layer and arranged one above and one below the electrically conductive layer are two dielectric layer sequences, each including n low-optical-refraction layers having an index of refraction less than 1.8 and (n+1) high-optical-refraction layers having an index of refraction greater than 1.8, arranged alternatingly in each case, wherein n is an integer greater than or equal to 1.

摘要： A material includes a transparent substrate coated with a functional coating, including, consecutively from the substrate, an alternation of three silver-based functional metal layers and four dielectric coatings (Di1, Di2, Di3 and Di4) which each have an optical thickness Eo1, Eo2, Eo3 and Eo4, each dielectric coating comprising at least one dielectric layer so that each functional metal layer is arranged between two dielectric coatings. The dielectric coating Di1 has an optical thickness Eo1 of less than 80 nm. The dielectric coating Di2 has an optical thickness Eo2 of less than 160 nm. The dielectric coating Di3 has an optical thickness Eo3 of less than 160 nm. The dielectric coating Di4 has an optical thickness Eo4 of less than 60 nm. Eo2/Eo1 is greater than 1.70 including this value. The thickness of the second functional metal layer is less than 12 nm. The thickness ratio Ag3/Ag1 is ≥1.20.
