Embodiments of a article including include a substrate and a patterned coating are provided. In one or more embodiments, when a strain is applied to the article, the article exhibits a failure strain of 0.5% or greater. Patterned coating may include a particulate coating or may include a discontinuous coating.

Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.

A projection arrangement for a head-up display, including a composite pane, including an outer pane and an inner pane, which are joined to one another via a thermoplastic intermediate layer, having an upper edge and a lower edge and an HUD region; an electrically conductive coating on the surface of the outer pane or the inner pane facing the intermediate layer or provided within the intermediate layer; and a projector that is aimed at the HUD region; wherein the light of the projector has at least one p-polarised portion and wherein the electrically conductive coating has, in the spectral range from 400 nm to 650 nm, only a single local reflection maximum for p-polarised light, with this maximum in the range from 510 nm to 550 nm.

A window is designed to prevent or reduce bird collisions therewith. In certain example embodiments, the window may be an insulating glass (IG) window unit, or alternatively a monolithic window. In IG window unit embodiments, the IG window unit includes first and second substrates (e.g., glass substrates) spaced apart from one another, wherein at least one of the substrates supports both a patterned ultraviolet (UV) absorbing coating for absorbing UV radiation, and a UV reflecting coating for reflecting UV radiation, so that a more contrasting UV image is emitted/seen and birds are capable of more easily seeing the window and avoiding collisions therewith. By making the window more visible to birds, bird collisions therewith and bird deaths can be reduced.
