Abstract: Systems and methods in which a thermal conductive composite comprises a non-uniform heat absorption profile of a thermal reactive material are described. Thermal conductive composites herein may be utilized in thermal regulatory modules with a gradient structure configured to transfer heat energy away from an area near a heat source to an area with a relatively large latent heat absorbing capacity. Thermal conductive material may be provided in a frame structure having lower porosity in a first region more near a heat source and higher porosity in a second region more distant from the heat source. A thermal reactive material may be deposited so as to be disposed within the pores of the thermal conductive material frame structure wherein the density of the thermal reactive material in the first region of the thermal conductive composite is lower than that at the second region of the thermal conductive composite.

Abstract: Technologies are provided for generating optimized sets of client rendering options for renderable content items (such as images, videos, text, and audio). Rendering optimization parameters for a renderable content item can be determined by assessing the performance of processing requests and rendering content items using different file formats, quality settings, and/or other settings for the renderable content items. The rendering optimization parameters can then be used in combination with a rendering specification that is defined by a developer (such as an application developer, web page designer, or the like) in order to create an optimized set of client rendering options. The set of client rendering options can then be transmitted to one or more client computing devices. A client computing device that receives the set of client rendering options can select one or more of the options in order to render the renderable content item.

Abstract: To provide more test data during the manufacture of non-volatile memories and other integrated circuits, machine learning is used to generate virtual test values. Virtual test results are interpolated for one set of tests for devices on which the test is not performed based on correlations with other sets of tests. In one example, machine learning determines a correlation study between bad block values determined at die sort and photo-limited yield (PLY) values determined inline during processing. The correlation can be applied to interpolate virtual inline PLY data for all of the memory dies, allowing for more rapid feedback on the processing parameters for manufacturing the memory dies and making the manufacturing process more efficient and accurate. In another set of embodiments, the machine learning is used to extrapolate limited metrology (e.g., critical dimension) test data to all of the memory die through interpolated virtual metrology data values.
