  • Patent number: 10472702
    Abstract: Differing from traditional alloys often containing one primary elemental composition, the present invention reforms a conventional superalloy to a high-entropy superalloy by redesigning the elemental compositions of the conventional superalloy based on a mixing entropy formula. Particularly, this high-entropy superalloy shows advantages of light weight and low cost under the premise of containing a low amount of expensive metal composition. The proposed high-entropy superalloy of the present invention comprises a primary elemental composition and at least one principal strengthening elemental composition, wherein the primary elemental composition has a first element content of at least 35 at % and each of the principal strengthening elemental compositions have a second element content of over 5 at %.

  • Publication number: 20190259130
    Abstract: Methods, apparatuses, and computer program products for overlaying multisource media in VRAM are described. The primary media source is rendered in VRAM by an application program, and then the secondary media source(s) are rendered and blended to the primary source in VRAM at the same location of the primary source in VRAM, so no extra buffer is needed. This improves system performance and reduces power consumption, through reduced system bus, system memory, and CPU usage.

  • Publication number: 20190040500
    Abstract: The present invention discloses a new alloy design of precipitation strengthened high entropy superalloy (HESA), which is composed of at least one principal element, a plurality of base element, and at least one precipitation strengthening element for controlling the elemental segregation between the high-entropy matrix and ordered precipitate. Through the addition of the precipitation strengthening element, while substituting the same amount of the principle element, not only the ordering energy and the volume fraction of strengthening precipitates, but also the mechanical strength of the alloy can be apparently elevated. Therefore, this newly-developed precipitation strengthened HESA can further improve the thermal capability and mechanical properties from the previously proposed high-entropy alloys.

  • Patent number: 9800183
    Abstract: An inverter electrically operatively connected to an electric machine and in communication with a controller is described. The inverter is electrically connected to a high-voltage DC power bus. A method for controlling the multi-phase inverter circuit includes monitoring, via the controller, a rotational speed of the electric machine during operation of the inverter in an over-modulation mode. The inverter is commanded to operate in a linear modulation mode when the rotational speed is within a speed range associated with objectionable audible noise generated by operating the electric machine in the over-modulation mode.
