Abstract:
As the automotive industry moves towards full autonomous vehicles, one of the leading enabling technologies to emerge has been camera-based vision. The ideal location for the main cameras is near the top center of the windshield. This give a broad forward field of view and the existing wiper and defroster systems can be used to keep the field of view clear. However, the optical quality of the typical soda-lime windshield degrades over time as the surface of glass reacts with the elements and is abraded by the wipers, dust and debris. A small chip, that would normally not be a problem anywhere else in the windshield, requires replacement or repair of the windshield if it is in the camera area. The laminate of the invention replaces the outer glass layer with one that is substantially more resistance to abrasion and weathering than standard soda-lime glass resulting in improved optical durability.
Abstract:
Functional layers do not have a good performance at lower temperatures. This limitation is overcoming by combining the functional layers with a resistive heating circuit. The heating circuit uses minimal power to maintain the glazing at or above the temperature required for acceptable operation.
Abstract:
Principles and embodiments of the present disclosure relate to unique asymmetric laminates and methods that produce the laminates where the laminate includes an external glass substrate having a thickness (t o ) and an internal glass substrate comprising a strengthened glass substrate having a thickness (t i ) in a range from about 0.05 mm to about 1 mm such that t o /t i is in a range from about 3 to about 20.
Abstract:
A laminated glazing comprising a first ply of glazing material and a second ply of glazing material joined by at least one ply of adhesive interlayer material is disclosed. The first ply of glazing material comprises a sheet of glass having a first composition and the second ply of glazing material comprises a sheet of glass having a second composition different to the first composition. The laminated glazing has (i) a peripheral region extending around the periphery of the laminated glazing, the laminated glazing having a surface compression stress in the peripheral region and (ii) an edge compression, wherein the magnitude of edge compression is greater than the magnitude of the surface compression stress in the peripheral region. A method of making such a laminated is provided. A glass sheet suitable for being incorporated in such a laminated glazing is also disclosed.
Abstract:
A laminate structure having a first glass layer, a second glass layer, and at least one polymer interlayer intermediate the first and second glass layers. In some embodiments, the first glass layer can be comprised of a strengthened glass having first and second surfaces, the second surface being adjacent the interlayer and chemically polished and the second glass layer can be comprised of a strengthened glass having third and fourth surfaces, the fourth surface being opposite the interlayer and chemically polished and the third surface being adjacent the interlayer and having a substantially transparent coating formed thereon. In another embodiment, the first glass layer is curved and the second glass layer is substantially planar and cold formed onto the first glass layer to provide a difference in surface compressive stresses on the surfaces of the second glass layer.
Abstract:
The disclosure is directed to a transparent armor laminate having a glass, glass ceramic or ceramic strike face layer, one or a plurality of glass, glass ceramic ("GC"), ceramic ("C") or polymeric ("P") backing layer behind the strike face layer, one or a plurality of spall catcher ("SC") layers behind the backing layer(s), and a thin cover glass layer laminated to the strike face, the thin layer being the first layer to be impacted by any incoming projectile or debris. The cover glass has a thickness =3mm. In another embodiment the cover glass thickness is =1mm. Additionally, a defrosting/defogging element is laminated between the cover glass and the strike face.
Abstract:
A heatable glazing is disclosed in which electrical heating elements such as fine wires are connected to a bus bar. The resistance of the bus bar is chosen such that, at the supply voltage of the installation, the bus bar provides heating of a portion of the glazing in which it is located.
Abstract:
Laminated glazing consisting of at least two glass sheets, and a method for making same, are disclosed.
