  • Patent number: 11314508
    Abstract: Technologies that are well-suited for use in size, weight, and power (SWAP)-constrained environments are described herein. A host controller dispatches data processing instructions to hardware acceleration engines (HAEs) of one or more field programmable gate arrays (FPGAs) and further dispatches data transfer instructions to a memory controller, such that the HAEs perform processing operations on data stored in local memory devices of the HAEs in parallel with other data being transferred from external memory devices coupled to the FPGA(s) to the local memory devices.

  • Publication number: 20210047577
    Abstract: Provided herein are lubricant compositions comprising renewable base oils as embodied by hydrocarbon mixtures with controlled structure characteristics in combination with lubricant additives that address performance requirements and stricter environmental and fuel economy regulations. The lubricant composition provides performance in the cold crank simulated viscosity (CCS) vs Noack volatility relationship, which allows for the formulation of lower viscosity engine oils with improved fuel economy, improved fuel economy retention, and retained LSPI prevention additionally conferring improved characteristics to other devices or apparatus requiring lubrication.

  • Patent number: 10086246
    Abstract: Golf clubs formed from bulk-solidifying amorphous metals (i.e., metallic glasses) having high elastic modulus and fracture toughness, and to methods of forming the same are provided. Among other components, the golf club materials disclosed enable fabrication of flexural membranes or shells used in golf club heads (drivers, fairways, hybrids, irons, wedges and putters) exhibiting enhanced flexural or bending compliance together with the ability to deform plastically and avoid brittle fracture or catastrophic failure when overloaded under bending loads. Further, the high strength of the material and its density, comparable to that of steel, enables the redistribution of mass in the golf club while maintaining a desired overall target mass.

  • Patent number: 9963763
    Abstract: Methods and apparatus for forming high aspect ratio metallic glass, including metallic glass sheet and tube, by a melt deposition process are provided. In some methods and apparatus a molten alloy is deposited inside a tubular channel formed by two concentrically arranged substrates, and shaped and quenched by conduction to the substrates in a manner that enables the molten alloy to vitrify prior to undergoing substantial shear flow. The deposition method allows the molten alloy to be deposited and formed while being quenched, without undergoing substantial shear flow.

  • Patent number: 9845523
    Abstract: The disclosure is directed to a method of forming high-aspect-ratio metallic glass articles that are substantially free of defects and cosmetic flaws by means of rapid capacitive discharge forming. Metallic glass alloys that are stable against crystallization for at least 100 ms at temperatures where the viscosity is in the range of 100 to 104 Pa-s are considered as suitable for forming such high-aspect-ratio articles.
