Abstract: A downhole power generation system includes a generator that generates AC input power having a variable input voltage that varies based on a rotational rate of a turbine, which in turn is based on a variable flow rate of a fluid flow. An active rectifier converts the AC power having the variable input voltage to DC power having a constant output voltage. This may increase the range of usable input voltages and decrease a number of flow kits used in a downhole drilling assembly.

Abstract: A computer-implemented technique for accessing textures by a graphics processing unit (GPU), includes determining a frequency with which a first texture is expected to be accessed by an application executing on a GPU, determining a frequency with which a second texture is expected to be accessed by an application executing on the GPU, determining to load memory address information associated with the first texture into a GPU register when the frequency is greater than or equal to a threshold frequency value, determining to load memory address information associated with the second texture into a buffer memory when the frequency is less than the threshold frequency value, receiving a draw call utilizing the texture, rendering the draw call using the first texture by accessing the memory address information in the GPU register, and the second texture by accessing the memory address information in the buffer memory.

Abstract: A light weight insulator blanket capable of repetitive use of extended duration as a cover, gasket, or the like for a vessel or conduit used in transporting, storing or processing molten or non-molten metal, particularly iron or steel, and in similar applications, including a principal insulator layer of a light weight, flexible, fibrous ceramic material having one or both surfaces covered by a thick protective layer of a light weight, flexible fibrous metallic material such as high-temperature stainless steel wool, monel metal wool, or a multi-layer knitted or woven material; the layers are securely bound to each other by metallic fastening means such as high temperature stainless steel wire stitching, staples, or rivets.
