摘要： Using the same image sensor to capture both a two-dimensional (2D) image of a three-dimensional (3D) object and 3D depth measurements for the object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor generates a multi-bit output in the 2D mode and a binary output in the 3D mode to generate timestamps. Strong ambient light is rejected by switching the image sensor to a 3D logarithmic mode from a 3D linear mode.

摘要： Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

摘要： A pull roll apparatus and method are described herein that can control a cross-draw tension and a down-draw tension of a glass sheet while manufacturing the glass sheet. In one embodiment, the pull roll apparatus includes a first driven stub roll pair, a second driven stub roll pair and a control device (e.g., PLC) that controls the first and second driven stub roll pairs while a first edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the first driven stub roll pair and while an opposing second edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the second driven stub roll pair. If desired, the pull roll apparatus may include a pulling roll assembly (located below the first and second driven stub rolls) or another set of driven stub roll pairs (located below the first and second driven stub roll pairs).

摘要： A pull roll assembly is described herein that is used to draw a glass sheet. The pull roll assembly includes a first roll assembly, a second roll assembly and a device (e.g., differential drive, sensor(s)). The device enables one to control the first and/or second roll assemblies based in part on pulling forces (e.g., glass contact normal force and/or required sheet pulling force) associated with a glass sheet while the glass sheet is being drawn between the first and second roll assemblies. A glass manufacturing system and method for using the pull roll assembly are also described herein.

摘要： Low-defect crystals are grown in a closed ampoule under a layer of encapsulant. After crystal growth, the crystal is separated from the melt and moved into the layer of encapsulant and cooled to a first temperature at which crystal growth stops. The crystal is then moved into the inert gas ambient in the ampoule and further cooled. The crystal can be separated from the melt by decanting the melt into an adjacent reservoir or by rotating the ampoule to rotate the crystal into the encapsulant layer.

摘要： Sheet glass of commercial quality is made by a Pittsburgh Process without using a shutoff. Instead, means are used to seal the kiln from the tank, and a water-cooled pipe is submerged in the glass and lowers suitably the flow; throughout ratio. The submerged pipe has a diameter of 1.2 to 5 inches and it is located so that it obstructs the return flow, being positioned so that its top is not above the midpoint of the depth of the glass, and so that its bottom is at least one-fifth of the depth of the glass above the bottom. In this way the benefits of having no shutoff are obtained; lower costs, and an avoidance of defects in the products caused by shutoff.
