    Abstract: A glass article comprises a glass substrate having a first major surface and a second major surface, the second major surface being opposite the first major surface. An opaque layer is disposed on the second major surface. The opaque layer comprises an optical density of greater than 3.0 such that portions of the glass substrate covered by the opaque layer comprise an average optical transmission of less than or equal to 0.5% for light from 400 nm to 700 nm. Within a sensor region of the glass article, the opaque layer comprises a plurality of ablated portion such that an average optical transmission of the glass article within the sensor region is greater than or equal 1.0% for the light from 400 nm to 700 nm as a result of the plurality of ablated portions.

    Abstract: Systems, devices, and techniques for manufacturing a crystalline material (e.g., large crystal material) through the solid state conversion of a polycrystalline material are described. A device may be configured to concurrently heat a volume of ribbon, such as an alumina ribbon, using multiple heat sources. For example, a first heat source may heat a first volume of the ribbon and a second heat source may concurrently heat a second volume, for example, within the first volume, where the ribbon may comprise polycrystalline material. The concurrent heating may drive grain growth in the polycrystalline material in at least the second volume, which may convert the polycrystalline material to crystalline material having one or more grains that are larger than one or more grains of the polycrystalline material. The processed ribbon may include a large crystal material or a single crystal material.

    Abstract: An extrusion system (100) includes at least one sensor (102, 104) to detect localized presence of oil (701) on an exterior surface (715) or skin of wet extrudate material (714 e.g., ceramic material having a honeycomb cross-sectional shape), and at least one infrared emitting device (106, 108) configured to impinge infrared emissions on at least a portion of the exterior surface responsive to one or more sensor signals. Localized impingement of infrared emissions may reduce presence of oil streaks (701) without undue differential drying of the extrudate skin (715), and avoid surface fissures that would otherwise result in fired ceramic bodies. Separately controllable infrared emitters (502), or at least one controllable infrared blocking or redirecting element (603), may be used to impinge infrared emissions on selected areas. A humidification section (120) arranged downstream of infrared emitters (106, 108) may be used to at least partially rehydrate the wet extrudate material, if necessary.

    Abstract: An invention disclosure discloses a composite structure. The composite structure includes a substrate layer (120), a conductive layer (140) and an overlayer (160). The substrate has a first face (124) and a second face (122). The conductive layer has a first face (148) and a second face (149). The first face of the conductive layer is disposed on the at least a part of the second face of the substrate layer. A portion (144) of the conductive layer has a resistivity at least about ten times higher than an adjacent region (146) on the conductive layer. The overlayer may have a first face (162) and a second face (166). The first face of the overlayer is disposed on at least a part of the second face of the conductive layer such that the conductive layer is disposed between the overlayer and the substrate layer. The substrate layer comprises a material that is optically transparent over at least a part of the electromagnetic spectrum from about 180 nm to about 20 μm. The conductive layer comprises a layer having a thickness of about 10 nm or greater and having a resistivity of about 10 Ohm-cm or less. The conductive layer comprises a material that may be optically translucent or opaque over at least a part of the electromagnetic spectrum from about 180 nm to about 20 μm.

    Abstract: A method for forming ion-exchanged regions in a glass article by contacting an ion source with at least one surface of the glass article, forming a first ion-exchanged region in the glass article by heating a first portion of the glass article with a laser, and forming a second ion-exchanged region in the glass article. Characteristics of the first ion-exchanged region may be different from characteristics of the second ion-exchanged region. A depth of the ion-exchanged region may be greater than 1 μm. A glass article including a first ion-exchanged region, and a second ion-exchanged region having different characteristics from the first ion-exchanged region.
