Publication number: 20240154495Abstract: A permanent magnet (PM) motor is provided to facilitate air movement through heat rejection equipment. The PM motor has a body, an upper bearing housing positioned on and extending upwardly from a top surface of the body, a shaft connected to and extending from the upper bearing housing and in communication with a fan, and a lower bearing housing positioned on and extending downwardly from a bottom surface of the body opposite the top surface.

Publication number: 20240085964Abstract: A system and method for updating power supply voltages due to variations from aging are described. A functional unit includes a power supply monitor capable of measuring power supply variations in a region of the functional unit. An age counter measures an age of the functional unit. A control unit notifies the power supply monitor to measure an operating voltage reference. When the control unit receives a measured operating voltage reference, the control unit determines an updated age of the region different from the current age based on the measured operating voltage reference. The control unit updates the age counter with the corresponding age, which is younger than the previous age in some cases due to the region not experiencing predicted stress and aging. The control unit is capable of determining a voltage adjustment for the operating voltage reference based on an age indicated by the age counter.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Sriram Sambamurthy, Sriram Sundaram, Indrani Paul, Larry David Hewitt, Anil Harwani, Aaron Joseph Grenat, Dana Glenn Lewis, Leonardo Piga, Wonje Choi, Karthik Rao

Patent number: 11886224Abstract: A processing unit of a processing system compiles a priority queue listing of a plurality of processor cores to run a workload based on a cost of running the workload on each of the processor cores. The cost is based on at least one of a system usage policy, characteristics of the workload, and one or more physical constraints of each processor core. The processing unit selects a processor core based on the cost to run the workload and communicates an identifier of the selected processor core to an operating system of the processing system.Type: GrantFiled: July 31, 2020Date of Patent: January 30, 2024Assignee: Advanced Micro Devices, Inc.Inventors: Leonardo De Paula Rosa Piga, Karthik Rao, Indrani Paul, Mahesh Subramony, Kenneth Mitchell, Dana Glenn Lewis, Sriram Sambamurthy, Wonje Choi

Patent number: 9347251Abstract: The invention is a simple, low-cost, mechanical device to be inserted in the hinge area of an open door of a parked vehicle to keep the door open while people or equipment are added to or removed from the automobile. A particular use of the invention is as a safety mechanism to hold the passenger-side door open while a disabled passenger is assisted in exiting the vehicle without the care-giving individual having to hold the door open or having the door slam shut on the disabled person. After this use, the device may be removed and stored in the glove compartment for easy access.Type: GrantFiled: November 29, 2015Date of Patent: May 24, 2016Inventor: Jerry Glenn Lewis
