The single chip sensor is positioned on the interlayer component such that a transmission from the single chip sensor passes through the third glass component and does not pass through the first glass component.

A manufacturing method for a laminated glass in which a plurality of glass plates are laminated, includes a first main forming step of heating a first glass plate to a first softening point or higher to perform a main forming; a second main forming step of heating a second glass plate to a second softening point or higher to perform the main forming; a first finish forming step of bending and forming the first glass plate into a desired shape; and a second finish forming step of bending and forming the second glass plate into a desired shape. The first and second main forming steps are performed by using a same forming die. A first condition for lowering a temperature of the first glass plate to below the first softening point and a second condition for the second glass plate are different from each other.

Methods are provided for fabricating electrochromic devices that mitigate formation of short circuits under a top bus bar without predetermining where top bus bars will be applied on the device. Devices fabricated using such methods may be deactivated under the top bus bar, or may include active material under the top bus bar. Methods of fabricating devices with active material under a top bus bar include depositing a modified top bus bar, fabricating self-healing layers in the electrochromic device, and modifying a top transparent conductive layer of the device prior to applying bus bars.

A composite glass pane having a first glass pane, a second glass pane, and an intermediate layer arranged between the first and second glass panes is described. The intermediate layer includes one cover layer based on a thermoplastic polymer, and a border seal. The first glass pane is arranged with an offset relative to the second glass pane, the intermediate layer is cut back along at least one edge of the composite glass pane by a border distance, and the border seal is arranged in a border gap delimited by the first glass pane, the second glass pane and the intermediate layer. The border seal contains a polymer fusible with a polymer of the cover layers.

A pre-stressed structure and a method for forming a pre-stressed structure are provided. The pre-stressed structure comprises a panel including a first region pre-stressed into a condition of membrane tension, resulting in the panel having increased transverse stiffness. The pre-stressed structure may further comprise a second region pre-stressed into a condition of membrane compression. The panel may be a plate or a shell and may form part of an insulating glass unit, which in turn may form part of a curtainwall unit.

A method for determining pane thicknesses and a wedge angle of a coated windshield for a projection arrangement of a head-up display. A wedge angle and a combination of glass thicknesses are determined by means of which the glass ghost image and the layer ghost image are optimally reduced. The method proceeds from a starting thickness of the two glass panes of the windshield for which that wedge angle is determined, in an iterative process, that represents an optimal compromise between the minimization of the glass ghost image and the minimization of the layer ghost image. Then, the glass thicknesses are determined varied within a specified range for each combination of the optimal wedge angles. Thus, it is possible, iteratively, to identify that combination of glass thicknesses that results in the least occurrence of ghost images, in addition to the associated optimal wedge angle.

An improved laminated assembly comprising functional elements with connections extending outside of the laminated assembly preventing air, moisture and water from entering the assembly as well as a method to prevent air, moisture and water from entering a laminated assembly.
