Patent number: 11943340Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.Type: GrantFiled: April 19, 2019Date of Patent: March 26, 2024Assignee: Intel CorporationInventors: Bo Cui, Cunming Liang, Jr-Shian Tsai, Ping Yu, Xiaobing Qian, Xuekun Hu, Lin Luo, Shravan Nagraj, Xiaowen Zhang, Mesut A.

Patent number: 11905585Abstract: A novel medium heavy alloy (MHA) a composition designed and processed such that the MHA has properties comprising a tensile strength of about 1527 MPa, a proof strength of about 1337 MPa, and an impact toughness of about 180 J, when the MHA is forged, and the tensile strength of about 1746 MPa, the proof strength of about 1571 MPa, and the impact toughness of about 55 J, when the MHA is agedly treated. The superior strength-toughness is attributed to the face-centered cubic matrix and/or the nano-sized secondary phases. The superior dynamic performance is attributed to the widening of adiabatic shear bands.Type: GrantFiled: May 4, 2020Date of Patent: February 20, 2024Assignee: NORTHWESTERN UNIVERSITYInventors: Xiaobing Hu, Shaozun Liu, Chunxu Wang, Yong Li, Vinayak P.

Publication number: 20220213569Abstract: An ultra-high strength steel (UHSS) includes a composition designed and processed such that the UHSS has properties comprising a tensile strength of about 2020 MPa, a yield strength of about 1781 MPa and a fracture toughness of about 105 MPa·m1/2. The composition incudes Co no more than 8 wt % of the UHSS. The excellent mechanical performance of the UHSS is achieved by nanoscale ?-NiAl and M2C precipitates. The strength and toughness of the UHSS are comparable to those of the commercially used Aermet100 and M54 steels, while the cost of the UHSS is extremely low because of low Ni—Co concentration. This notable cost advantage makes the novel UHSS very competitive for potentially broad applications as structural components in the field of aerospace.Type: ApplicationFiled: May 4, 2020Publication date: July 7, 2022Inventors: Xiaobing Hu, Shaozun Liu, Chunxu Wang, Yong Li, Vinayak P.

Patent number: 7726946Abstract: A hub mounting assembly for mounting a plurality of impellers onto a shaft has a first hub ring and a second hub ring. A first key piece is adapted to engage with the shaft and engage with at least one of the hub rings, and a first lock pin is adapted to engage with the shaft and engage with at least one of the hub rings. In the installed state, the first hub ring is adapted to be fastened to the second hub ring, to trap the key piece and lock pin in a position so that the hub rings together form a hub that is locked against rotation and axial movement with respect to the shaft.Type: GrantFiled: November 16, 2006Date of Patent: June 1, 2010Assignee: SPX CorporationInventors: Xiaobing Hu, Robert Blakley, Rory Heinlein

Patent number: 7488137Abstract: A hub for removable mounting onto a shaft has an inner sleeve having a first end and a second end, and having a substantially cylindrical inner diameter and having an outer surface having a threaded region and a tapered conical surface located substantially near the first end. An outer hub has an inner surface with a threaded region threadably engagable with the threaded region of the inner hub, and a inner tapered conical surface configured to cam along the tapered outer surface of the inner hub. The hub can be locked at a desired axial location or the shaft by engaging the threads to cause the cam surfaces to constrict the diameter of the first end so it frictionally locks onto the shaft.Type: GrantFiled: December 30, 2004Date of Patent: February 10, 2009Assignee: SPX CorporationInventors: Xiaobing Hu, Anthony C.
