Abstract: A substrate (100) comprising a sheet of either a glass, a glass ceramic, or a ceramic and having increased edge strength. A polymeric edge coating (120) prevents creation of strength limiting defects along the edges of the substrate and protects the bend strength of the edges. The substrate may also have at least two parallel high strength edges (110, 112) and an edge coating (120) of a polymeric material covering at least a portion of each of the high strength edges to preserve the high strength edges from the introduction of defects and damage to the edges. Each of the two parallel high strength edges has a bend strength that is capable of less than about 2% failure probability at a stress level of 200 MPa over a test length of 50 mm. A method of making the substrate is also provided.

Abstract: Packages and methods of packaging a plurality of glass sheets provide a stack of glass sheets with an interleaf protective sheet positioned between each adjacent pair of glass sheets. An outer portion of each interleaf protective sheet is bent over a portion of the peripheral edge of one of a corresponding adjacent pair of glass sheets to discourage relative shifting of the glass sheets with respect to one another. The stack of glass sheets are sandwiched between pressure members of an outer housing such that the pressure members each apply a support pressure that is distributed over an outer surface of a corresponding one of the pair of outermost glass sheets of the stack of glass sheets.

Abstract: A synthetic acceleration shape bound primitives composing a 3-D scene, and is defined using a group of fundamental shapes arranged to bound the primitives, and for which intersection results for group members yield an ultimate intersection testing result for the synthetic shape, using a logical operator. For example, two or more spheres are used to bound an object so that each of the spheres is larger than a minimum necessary to bound the object, and a volume defined by an intersection between the shapes defines a smaller volume in which the object is bounded. A ray is found to potentially intersect the object only if it intersects both spheres. In another example, an element may be defined by a volumetric union of component elements. Indicators can determine how groups of shapes should be interpreted. Synthetic shapes can be treated as a single element in a graph or hierarchical arrangement of acceleration elements.

Abstract: An apparatus for redirecting a glass ribbon assembly from a first glass conveyance path to a second glass conveyance path. The apparatus includes a glass ribbon assembly source for providing the glass ribbon assembly including a flexible glass substrate that includes a first surface and a second surface that extend between a first edge and a second edge, first and second handling tabs affixed to the flexible glass substrate edges, and a primary roll member located downstream of the glass ribbon assembly source. The first glass conveyance path extends from the glass ribbon assembly source to the primary roll member, and the second glass conveyance path extends from the primary roll member in a downstream direction. Contact surfaces of the primary roll member are tangential to the first and second glass conveyance paths, and the second glass conveyance path is non-planar with the first glass conveyance path.

Abstract: An implantable medical lead may include a longitudinally extending body, an electrical conductor, an electrical component, and a weld. The longitudinally extending body includes a distal end and a proximal end. The electrical conductor extends through the body between the proximal end and the distal end. The electrical component is on the body and includes a sacrificial feature defined in a wall of the electrical component. The sacrificial feature includes a region that continues from the wall of the electrical component and a side that is isolated from the wall of the electrical component via a void defined in the wall of the electrical component. The weld is formed at least in part from at least a portion of the sacrificial feature. The weld operably couples the electrical component to the electrical conductor.

Abstract: A method and system is provided to separate calcium carbonate inorganic eggshell from the inner lining of organic protein-based membrane in eggshell by-product. The method involves three phases: mechanical agitation/separation, functional chemical digestion and refining chemical digestion. In the mechanical stage, agitation and sieving are used to remove large pieces, and the majority of, membrane material. In the functional chemical digestion stage, the by-product is processed through at least one basic solution to remove additional organic membrane and impurities. In the refining chemical digestion stage, the remaining organic membrane and impurities are removed. The purified calcium carbonate is then rinsed and dried, in preparation for further refinement and processing to finished goods specifications.

Abstract: A method of forming a flexible glass-polymer laminate structure includes heating a polymer layer to an elevated temperature of greater than 20° C. and below a working temperature of a flexible glass substrate adjacent the polymer layer. The flexible glass substrate has a thickness of no more than about 0.3 mm. The flexible glass substrate is shaped with the polymer layer at the elevated temperature. The polymer layer is cooled below the elevated temperature such that the flexible glass-polymer laminate structure maintains a non-planar formation.

Abstract: A profiler for a ray tracing renderer interfaces with the renderer to collect rendering information, such as ray definition information, a pixel origin, objects hit, shader invocation, and related rays. In an interface, an artist views a simplified 3-D scene model and a rendered 2-D image. A pixel in the 2-D image is selectable; the profiler responds by populating the simplified 3-D scene with rays that contributed to that pixel. Rays can be displayed in the simplified 3-D scene to visually convey information about characteristics of each ray, such as whether the ray intersected an object, portions of the scene where it is occluded, and a direction. Statistics can be produced by the profiler that convey information such as relative computational complexity to render particular pixels. The profiler can step through multiple passes (e.g., multiple frames and passes of a multipass rendering), and the UI can allow pausing and stepping.
