  • Patent number: 12109784
    Abstract: Tie layers and structures that exhibit superior properties and that provide desirable optical properties when incorporated into laminates, such as windshields, windows or other glazings containing a holographic optical element (HOE) are disclosed. The tie layers, when used in a laminate in conjunction with the HOE film, optionally with additional polymer layers, maintain and do not detract from the HOE film properties.

  • Publication number: 20240239084
    Abstract: Windshields are disclosed herein having an optical path, that include an inner rigid substrate, optically adjacent a first wedge polymer layer, that serves to reflect a primary image. A reflective layer is also provided, positioned in the optical path between the first wedge polymer layer and a second wedge polymer layer. The windshields are further provided with an outer rigid substrate, optically adjacent the second wedge polymer layer. The first wedge polymer layer causes visible light reflected from the reflective layer to overlap the primary image, and the second wedge polymer layer causes visible light reflected from an outer face of the outer rigid substrate to overlap the primary image.

  • Publication number: 20240004114
    Abstract: Display systems and methods are disclosed for displaying images, while preventing or reducing unintended viewing. A projector is provided that emits light toward a viewing surface at three discrete wavelength ranges to create an image. A light-absorbing substrate is also provided, disposed between the viewing surface and the unintended viewer, incorporating narrow-band absorbers that selectively absorb light within the three wavelength ranges, thus reducing or eliminating the image perceived by the unintended viewer.

  • Patent number: 9242401
    Abstract: The present invention is directed to the use of injection molding to form polymeric interlayers directly between two rigid substrates that are positioned so that after injection of the melted polymeric material and after cooling, the resulting multiple layer panel functions as a safety panel that can be used in any appropriate conventional safety glazing application. Methods of the present invention utilize a relatively low molecular weight polymer, multiple injection points, mold compression, and/or a heated substrate in order to facilitate the injection of polymer into the relatively narrow space between glazing substrates that is typically found in safety glazings.

  • Patent number: 8124868
    Abstract: The present invention provides a thin film photovoltaic module that has a protective substrate, such as glass, that has been contoured to define a space that allows air to avoid entrapment by a bus bar on the thin film photovoltaic device. The contouring of the protective substrate greatly facilitates the deairing and lamination of the module because it reduces or eliminates the amount of trapped air during lamination. Photovoltaic modules of the present invention can be processed with a minimum of waste caused by deairing and related lamination problems.
