Abstract: Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.

Abstract: Apparatus and method for testing a sheet of brittle material comprising the steps of measuring one or more edge features of a sheet of brittle material, imparting a bend to the sheet of brittle material and producing relative motion between the sheet and the bend such that the bend traverses the sheet. A stress can be induced in the sheet as a function of the relative motion and imparted bend, wherein the induced stress corresponds to a predetermined strength value, and the measured one or more edge features can be correlated with the strength value.

Abstract: An apparatus for testing the edge strength of a discrete sheet of material such as glass where the sheet has an irregular free-form shaped outline is disclosed. The apparatus can include a plurality of assemblies configured for selectively applying a 3-point bending load on an edge of the sheet of material in a test region of the apparatus, a detection mechanism that optically measures strain in the sheet of material in the region, and a processor that determines the stress in the sheet based on the measured strain by calculating the stress that would be required to produce the measured strain in the sheet of material.

Abstract: Disclosed herein are apparatuses and methods for measuring electrostatic charge on a surface of a substrate. The apparatuses comprise a substrate mounting platform, a substrate contacting component, and at least one voltage sensor, wherein the apparatus is programmed to independently control the rotational and translation velocity of a roller and/or to measure a voltage of the substrate at multiple points to produce a two-dimensional map of voltage for at least a portion of the substrate.

Abstract: Methods of processing or modifying a glass substrate such as a glass sheet are disclosed. A method includes contacting at least one of opposing major surfaces of the glass sheet with a fluid applicator apparatus and a liquid etchant composition including acetic acid, ammonium fluoride, and water, the contacting conducted at a predetermined transfer rate of the liquid etchant to the at least one of the opposing major surfaces. The predetermined liquid transfer rate is controlled to adjustably texture the at least one of the opposing major surfaces and provide a textured major surface, wherein when the textured major surface and a planar surface are placed in contact, there is an adhesion force between the textured major surface and the planar surface, and wherein the adhesion force is within a target adhesion force range.
