  • Patent number: 10508054
    Abstract: A vehicle glazing includes on its surface to be exposed to the exterior atmosphere, at least in a zone not wiped by the windscreen wipers, a mineral oxide layer of 0.1 to 20 ?m thickness, 30 to 90% of the volume of which consists of 20 to 300 nm open pores that are distributed uniformly throughout the thickness of the layer, and almost all of which are connected to one another, the internal and external surface of the layer being functionalized with a compound containing a perfluoroalkyl or alkyl functional group, then saturated with a hydrophobic oil that impregnates the functionalized porous layer and forms a film on the surface thereof, the at least one zone being located facing a detecting device such as an anti-collision/obstacle-detecting/security video camera, or similar, placed in the interior of the vehicle, in particular on the face of the glazing.

  • Patent number: 9846265
    Abstract: A transparent layered element with diffuse reflection properties includes two outer layers made of dielectric materials having substantially the same refractive index and a central layer intercalated between the two outer layers, formed either from a single layer which is a dielectric layer with a refractive index different from that of the outer layers or a metallic layer, or from a stack of layers which includes at least one dielectric layer with a refractive index different from that of the outer layers or a metallic layer. The upper outer layer is a sol-gel layer including a silica-based organic/inorganic hybrid matrix.
