Abstract: Processes and devices by which a brittle material substrate may be edge formed and finished to simultaneously remove corresponding damage remaining on the edges in the areas formed by cutting and separation while imposing a desired edge profile and achieving a desired mechanical edge strength. Processes of the present disclosure may include a chemical and mechanical brush polishing process configured to shape and/or polish a surface of one or more thin substrates. A plurality of substrates may be arranged in a stacked configuration, and engineered interposer devices may be arranged between the stacked substrates. The interposers may provide between the substrates and may direct filament placement during brushing so as to guide material removal on the substrate edges. Substrate edge profile shapes, including symmetric and asymmetric profiles, may be formed by strategic manipulation of interposer properties including dimensions, mechanical features, material properties, and positioning.

Abstract: The method of controlling service load selectively by session in the telecommunications charging system is designed to ensure stable system operation even when the load exceeds the system's capacity. The method consists of three steps: Step 1: the charging system determines the overload status of the system; Step 2: The charging system selectively bypass or accept request according to conditions and has a status memory; Step 3: The charging system analyzes and reprocesses the saved charging requests.

Abstract: A method for processing a transparent workpiece includes forming a contour of defect in the transparent workpiece and separating the transparent workpiece along the contour using an infrared laser beam. During separation, the method also includes detecting a position and propagation direction of a crack tip relative to a reference location and propagation direction of an infrared beam spot, determining a detected distance and angular offset between the crack tip and the reference location of the infrared beam spot, comparing the detected distance to a preset distance, comparing the detected angular offset to a preset angular offset, and modifying at least one of a power of the infrared laser beam or a speed of relative translation between the infrared laser beam and the transparent workpiece in response to a difference between the detected distance and the preset distance and between the detected angular offset and the preset angular offset.

Abstract: A device for locating target points on a magnetic resonance image of the brain of a subject includes a trained neural network configured to receive as input a 3D MR image of the brain of a subject, and to output the location, on the image, of at least one determined brain target point. The neural network includes a plurality of processing stages. Each processing stage processes an image at a respective resolution, and the processing stage of lowest resolution outputs an estimate of the location of each target point. Each other processing stage is configured to receive, from a lower resolution processing stage, an estimate of the locations of the target points, crop the input image to a smaller region surrounding each estimated target point, determine an updated estimate of the location of each target point, and provide the updated estimation to the processing stage of the next higher resolution.

Abstract: A method for laser processing a transparent workpiece includes forming a contour line in the transparent workpiece and directing an infrared laser beam output by an infrared beam source through an a focal beam adjustment assembly and onto the transparent workpiece along the contour line to separate the transparent workpiece along the contour line. The infrared laser beam forms an annular infrared beam spot on a surface of the transparent workpiece. The infrared laser beam includes an entrance beam diameter upstream the afocal beam adjustment assembly and an exit beam diameter downstream the afocal beam adjustment assembly. The annular infrared beam spot includes an inner diameter, an outer diameter, and an annular thickness. Further, the focal beam adjustment assembly includes one or more adjustable optical elements. Moreover, adjusting the one or more adjustable optical elements alters the exit beam diameter, thereby altering the annular thickness of the annular infrared beam spot.

Abstract: The invention provides an energy dispersion device, spectrograph and method that can be used to evaluate the composition of matter on site without the need for specialized training or expensive equipment. The energy dispersion device or spectrograph can be used with a digital camera or cell phone. A device of the invention includes a stack of single- or double-dispersion diffraction gratings that are rotated about their normal giving rise to a multiplicity of diffraction orders from which meaningful measurements and determinations can be made with respect to the qualitative or quantitative characteristics of matter.

Abstract: The invention is a method for Web authors to include a redirection tag in an HTML data object tag that redirects an application program to an alternative source file that stores underlying data associated with an HTML data object that a user has selected to import into the application program. Typically, HTML data objects in Web page are stored in HTML format. However, when a user selects an HTML object to import, they generally expect to import the data in the format that it was originally created in, such as XML. The redirection tag “redirects” the application program to an alternative source file where the underlying data is stored in a rich format, such as XML. The application program then imports the underlying data of the HTML data object from the alternative source file.

Abstract: A circuit is designed with a detector circuit (700) coupled between a supply voltage terminal (705) and a reference voltage terminal (755). The detector circuit produces a first control signal in response to a detected mode and produces a second control signal in response to another mode. A first circuit (205, 207) including a delay circuit receives the first control signal and a third control signal. The delay circuit produces a fourth control signal at an output terminal (215) in response to the first and third control signals. A second circuit (203) receives the second control signal and the third control signal. The second circuit produces the fourth control signal at the output terminal in response to the second and third control signals.
