Patent number: 11842436Abstract: Techniques are disclosed relating to arbitration for computer memory resources. In some embodiments, an apparatus includes queue circuitry that implements multiple queues configured to queue requests to access a memory bus. Control circuitry may, in response to detecting a first threshold condition associated with the queue circuitry, generate a first snapshot that indicates numbers of requests in respective queues of the multiple queues at a first time. The control circuitry may generate a second snapshot that indicates numbers of requests in respective queues of the multiple queues at a second time that is subsequent to the first time. The control circuitry may arbitrate between requests from the multiple queues to select requests to access the memory bus, where the arbitration is based on snapshots to which requests from the multiple queues belong. Disclosed techniques may approximate age-based scheduling while reducing area and power consumption.Type: GrantFiled: August 1, 2022Date of Patent: December 12, 2023Assignee: Apple Inc.Inventors: Winnie W. Yeung, Leela Kishore Kothamasu, Zelin Zhang, Guanlan Xu, Eddie M. Robinson

Patent number: 11630926Abstract: The present invention discloses an optimization method for a screen surface dynamic load of a vibrating screen. The method includes the following steps: step 1. selecting design variables, and establishing an experimental matrix; step 2. performing a response curved surface experiment; step 3. establishing two double-objective optimization models and solving the same to obtain two groups of Pareto solution sets, wherein the solution sets respectively represent screening efficiency optimization paths of the vibrating screen under the conditions of a high screen surface dynamic load and a low screen surface dynamic load; and step 4. calculating an optimization space for a screen surface dynamic load under a high screening efficiency. According to the method of the present invention, the screen surface dynamic load can be directly reduced, and the service life of the screen surface and the whole vibrating screen is prolonged.Type: GrantFiled: July 21, 2022Date of Patent: April 18, 2023Assignee: Wuhan University of Science and TechnologyInventors: Lei Wang, Yuyao Guo, Zelin Zhang, Xuhui Xia, Jie Long, Xiang Liu, Weimin Jing, Xuguo Yan, Baotong Chen, Tong Wang, Jianhua Cao, Huan Zhang, Jinliang Zhou, Wu Guo

Publication number: 20210241178Abstract: Embodiments discussed herein facilitate determination of risk of relapse of AML post-transplant. One example embodiment is a method, comprising: accessing a digital whole slide image (WSI) comprising a post-transplant bone marrow aspirate from a patient that has acute myeloid leukemia (AML); segmenting one or more myeloblasts on the digital WSI; extracting one or more features from the segmented one or more myeloblasts; providing the one or more features extracted from the segmented one or more myeloblasts to a trained machine learning model; and receiving, from the trained machine learning model, an indication of a risk of relapse of the AML.Type: ApplicationFiled: February 4, 2021Publication date: August 5, 2021Inventors: Anant Madabhushi, Sara Arab Yarmohammadi, Zelin Zhang, Patrick Leo, Leland Metheny, Howard Meyerson

Patent number: 10555866Abstract: A collapsible wheeled walker with two side frames and two height adjustable upper body supports. The apparatus includes a plurality of wheel direction locks each coupled to a wheel and adapted to lock the wheel in fixed moving direction or to release the wheel to turn freely. The apparatus may include a seat that is slidably attached to the two side frames and is movable between a front position for walking inside the frames and a rear position sitting. The apparatus may be converted to a transport chair by locking front wheel and releasing the rear wheels, and sliding the movable seat to the rear position. It may include an X-folder that facilitates collapsing the walker to a small footprint. It may also include two forearm gutters as part of the upper body supports that give the user an upright walking posture for health benefits.Type: GrantFiled: January 15, 2018Date of Patent: February 11, 2020Assignee: ProtoStar, Inc., a Delaware CorporationInventors: Yichuan Pan, Peter James Fellingham, Zelin Zhang, David Allen Purcell, David Michael Petersen, Scott Allen Rieger
