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: In addition to providing for vision and protection from the external elements, various other features, such as lighting, cameras, sensors and displays have been integrated within automotive glazings. Some of these require a laminate with an offset between the edges of at least two of the glass layers to accommodate components and/or connectors. When the edge of one glass layer is offset, such that it is no longer substantially captured by the mounting means used to install the glazing in the vehicle, the mechanical strength is reduced. To compensate, the remaining layer must be made stronger, usually by increasing the thickness. Even when compensated, the security of the glazing remains compromised as the smaller glass layer is not directly connected to the vehicle. If the larger glass layer should break, the opening may be left unprotected. By providing an innovative integrated reinforcement in the offset portion, a secure, stronger and lighter laminate can be obtained.

Abstract: It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).

Abstract: The present invention discloses an automotive switchable glazing that changes the visible and near infrared light transmittance properties of the glazing with passive materials. Opposite to expensive technology such as active switchable materials, the 5 level of darkness of the thermochromic materials of the present invention can be dynamically controlled by means of including thermochromic materials placed in contact with any of the interior surfaces of the outer or the inner glass layers, in combination with a plastic layer placed in contact with any of the interior surfaces of the outer or the inner glass layers. The visible light transmittance of the automotive 10 switchable glazing of the present invention ranges from 0.1% to 10% in the visible spectrum. Likewise, the near infrared light transmittance is between 20% to 80% in the near infrared spectrum.

Abstract: The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result a high level of distortion in the camera field of view. The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by creating an obscuration, after heating and bending of the glass, by printing the obscuration on one or more of the surfaces of the bent glass in or near the camera field of view (camera obscuration) or / and in the edges of the windshield (black band) rather than printing and firing an enamel frit on the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.

Abstract: The laminated glass panoramic roof is a popular option offered on a growing number of automobiles. Much of its appeal comes from the open airy feel that it imparts upon the cabin and the sleek modern appearance that it gives to the vehicle. However, as the quantity, brightness and the size of instrument and information displays has increased reflected light, from the panoramic roof, has become more and more of a concern. The invention, through the application of glass surface treatments in combination with glass compositions and plastic interlayers, significantly reduces these reflections improving the interior aesthetic of the laminate.

Abstract: The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves for full autonomous capability, the number of cameras required is increasing. At the same time, windshields, where many of the cameras are mounted are 5 becoming larger and more complex in shape. This presents problems in the area of camera optics. For one, the camera is looking out through at least two layers of bent glass bonded together by a third layer of plastic. Mismatches in the refractive index can result in a double image. The curvature of the glass turns the window into a lens and, in conjunction with the often low installation angle, can reduce the optical clarity of the camera field of view. The 0 laminate of the invention has a cutout in the area of the camera(s) on the interior glass layer where the cameras are mounted. The cameras are mounted directly to the glass via a bracket or adhesive or to a thin transparent insert. The glass can also be fitted with a lens system optically bonded to the glass for even better performance. The result is a laminated glazing with superior optical quality.

Abstract: As the use of laminated glass in vehicles has extended beyond just the windshield, the total glazed area and size of the glass parts has been increasing. It is also noted that the thickness of the glass decreasing with the introduction of new technologies such as chemical tempering being used as the automotive OEMs strive to reduce weight to improve efficiency. Unfortunately, as the mass of the glazing decreases and the area increases, the sound dampening ability of the glazing decreases. The invention substantially improves acoustic performance by distributing the mass of the laminated glass across three equivalent layers rather than just two as in a conventional laminate.
