    Abstract: As car manufacturers have worked to improve the fuel efficiency of their vehicles, one of the areas where they have been able to make major improvements has been aerodynamics. As most of the drag is the result of the frontal area of the vehicle, the installation angle of the windshield has been getting smaller and smaller to facilitate the smooth displacement of air. One of the drawbacks of this approach is that the light reflected back to the driver by the windshield increases as the installation angle decreases and the incidence angle increases. At high incidence angles, the intensity of the reflection may become objectionable. The invention reduces reflection at high incident angles by means of an anti-reflective layer and a polarization layer.

    Abstract: The increase in the electronic content of automotive glazing has expanded, from just components mounted to the glass, to components which are an integral permanent part of the glass. One component, which is becoming more and more common, is the camera. The use of camera-based safety systems, requiring a wide field of view and a high level of optical clarity, is growing at a rapid rate. As the industry moves towards full autonomous capability, the number of cameras and the resolution of the cameras are both increasing. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. The windshield, as an integral part of the camera lens system, is less than optimal. The light has to pass through layers of glass and plastic leading to distortion, attenuation, color shift and double image as well as calibration issues. The effects of the windshield on the optical quality are mitigated by the invention by integrating the camera into the laminate.

    Abstract: The present invention discloses a vehicle glazing having a sharply curved portion and the method for bending such glazing. The sharply curved portion of the glass may extend along the surface of the glass. The sharply curved portion is obtained by locally heating by means of a laser source, heating the portion of the glass to a temperature sufficiently high enough to allow said portion of glass to bend. In preferred embodiments, the sharply curved portion comprises a first bent portion described by a first radius and a second bent portion described by a second radius, wherein the point where the radiuses of the first and second bent portions change their orientation generate an inflection point. The radius of curvature of the first and second bent portions is of less than 150 mm.

    Abstract: The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. This presents problems in the area of camera optics. Variations in the thickness of the glass and the plastic layer, surface mismatch, surface texture and the design curvature of the glass in conjunction with the often low installation angle, can reduce the optical clarity of the camera optics. These optical aberrations are further exacerbated during the lamination process when the layers are bonded together under pressure. The laminate of the invention utilizes a cutout in the plastic bonding layer in side of the laminate, preferable in the camera field of view. A laminating resin is used to fill the gap left by the cutout between the two glass layers.

    Abstract: Glazing mounting systems, that make use of an adhesive to bond the glazing to a vehicle opening, require an obscuration to hide the adhesive from view and to protect the adhesive from ultra-violet radiation. An enamel ink is typically used to print the obscuration on the glass. However, glass with certain types of coatings and glass which will be chemically tempered is not compatible with enamel frits. Organic inks can be used but are expensive, difficult to work with and not as durable as an enamel frit. The obscuration of the present invention is produced by replacing the printed obscuration with an insert, which serves the same function of an obscuration printed on the glass, which is laminated as a part of the glazing.
