    摘要: Method for cutting a glass layer having a first surface a second surface. The method includes moving a first laser beam, which is generated by a pulsed laser, along a cutting line, where material modifications are produced in the interior of the glass layer between the first surface and the second surface; moving a second laser beam along the cutting line where the glass layer is heated by the laser radiation; and cooling the glass layer along the cutting line, where the glass layer breaks along the cutting line.

    摘要: A material includes a transparent substrate coated with a stack of thin layers acting on infrared radiation including at least one functional layer. The stack includes a carbon-based upper protective layer within which the carbon atoms are essentially in an sp2 hybridization state and the upper protective layer is deposited above at least a part of the functional layer and exhibits a thickness of less than 1 nm.

    摘要: A windshield with an electrically controllable sun visor is described. The windshield includes an outer pane and an inner pane that are bonded to one another via an intermediate layer. According to one aspect, a functional element with electrically controllable optical properties is incorporated into the intermediate layer and above a central field of vision. The functional element is connected to the outer pane via a region of a first thermoplastic layer, and is connected to the inner pane via a region of a second thermoplastic layer. According to another aspect, the region of the first thermoplastic layer and/or the region of the second thermoplastic layer is tinted or colored.

    摘要: A projection arrangement for a head-up display (HUD) is presented. The arrangement has a vehicle windshield that includes an outer pane and an inner pane bonded to one another via a thermoplastic intermediate layer. The vehicle windshield has an upper edge, a lower edge, and an HUD region. The arrangement also has a projector that is aimed at the HUD region to generate a virtual image perceivable by an observer situated within an eyebox. According to one aspect, the windshield has an HUD reference point, at which a central beam running between the projector and the center of the eyebox strikes the inner pane. According to another aspect, the thickness of the thermoplastic intermediate layer in the vertical course between the upper edge and the lower edge in at least a section corresponding to the HUD region is variable according to a wedge angle.
