Patent number: 11941444Abstract: Examples described herein include automated discovery of hardware resources of nodes of a container cluster to facilitate pod scheduling. According to an example, discovery pods are launched on respective nodes of the container cluster. The discovery pods are privileged pods with an ability to query respective operating systems of respective nodes regarding hardware associated with the respective nodes. Information regarding local block devices associated with the respective nodes are discovered by the discovery pods running thereon. Scheduling of storage system pods on nodes of the container cluster that satisfy storage characteristics specified by respective pod requests are facilitated by creating a raw block persistent volume (PV) for each of the discovered local block devices or a subset thereof.Type: GrantFiled: August 27, 2021Date of Patent: March 26, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Skyler Thomas, Mark A.

Patent number: 9846469Abstract: A fault tolerant power supply system includes at least one load switch circuit configured to connect, using a main switch, an input voltage to an output node of the load switch circuit when the load switch circuit is turned on and at least one power channel coupled to the load switch circuit to receive the input voltage. The power channel is configured as a buck converter and includes at least a high-side power switch and a low-side power switch. The fault tolerant power supply system is configured to measure a current flowing through the main switch of the load switch circuit, to determine that the current flowing through the main switch of the load switch circuit has exceeded a current limit threshold, and to disable the main switch of the load switch circuit and the low-side power switch of the power channel in response to the determination that the current flowing in the main switch has exceeded the current limit threshold.Type: GrantFiled: May 16, 2016Date of Patent: December 19, 2017Assignee: Alpha and Omega Semiconductor IncorporatedInventors: Mark Tomas, Zhiye Zhang, Allen Chang, Kuang Ming Chang, Gilbert Lee, Son Tran

Publication number: 20030120181Abstract: The present invention provides a medical guide wire and a method of making same in which, an elongated solid core wire is made of NiTi alloy with a Ni content of about between 55.0 and 56.5 wt % and a reverse martensitic transformation start temperature (As) in the fully annealed state of not more than 55° C. The wire has been thermomechanically processed to exhibit a work-hardened pseudoelasticity. After the last full annealing to regain workability, the wire is cold drawn with a significant amount of cold reduction of greater than 35%, but preferably greater than 38% The entire guide wire is subjected to the same heat treatment. The wire is formed into an elongated solid core. The heating step includes passing the wire through a tube furnace at substantially 280° C. to 370° C. The entire guide wire is subjected to the same heat treating step. The guide wire has centerless grinding performed at an appropriate stage to provide a taper section and a distal section.Type: ApplicationFiled: November 4, 2002Publication date: June 26, 2003Applicant: Memry CorporationInventors: Mark Toma, John Tommessilli, Scott Carpenter, Jesse Perez
