Abstract: Making a glass-based article having a coating and a target shape which comprises a planar central portion and a perimeter portion which borders at least part of the planar central portion and extends out of the plane of the planar central portion, the perimeter portion having a perimeter edge and a target edge-to-opposite edge dimension. The method includes forming a glass-based part to provide an initial formed part having an initial three-dimensional shape that is different from the target shape for at least the target edge-to-opposite edge dimension. Applying a coating to the initial formed part to form the glass-based article having a coating, the coating imparting a stress to the initial molded part that causes a calculated, warp-induced change to the initial shape.

Abstract: A strain relief boot and a fiber optic cable assembly are described. The strain relief boot has a first conduit made of at least a first material. The first conduit has a front segment and a rear segment. The rear segment includes at least one discontinuity to make the rear segment more flexible than the front segment. The rear segment also includes at least one projection extending outwardly from the rear segment at a location adjacent to the at least one discontinuity. The strain relief boot also has a second conduit made from at least a second material that is less rigid than the first material. The second conduit at least partially surrounds at least the rear segment of the first conduit and extends rearwardly of the first conduit.

Abstract: Methods for compensating for the warp exhibited by three-dimensional glass covers as a result of ion exchange strengthening are provided. The methods use a computer-implemented model to predict/estimate changes to a target three-dimensional shape for the 3D glass cover as a result of ion exchange strengthening. The model includes the effects of ion exchange through the edge of the 3D glass cover. In an embodiment, the inverse of the predicted/estimated changes is used to produce a compensated (corrected) mold which produces as-molded parts which when subjected to ion exchange strengthening have shapes closer to the target shape than they would have had if the mold had not been compensated (corrected).
