Patent number: 11599437Abstract: A mechanism is provided for automatically detecting, diagnosing, transporting, and repairing devices having failed during burn-in testing. Embodiments provide a system that monitors devices undergoing burn-in testing and detecting when a device or a component within a device fails the burn-in test. Embodiments can then alert burn-in-rack monitor personnel of the device failure. Embodiments can concurrently determine the nature of the failure applying a machine learning-based prediction model against log files associated with the failed device. The diagnosis along with a recommended repair strategy can be provided to the repair center as an aid in accelerating the repair process. In addition, the diagnosis can be used to order parts for the repair from a parts depot. In this manner, embodiments can reduce the time for detection, diagnosis, and repair of the failed device.Type: GrantFiled: February 22, 2021Date of Patent: March 7, 2023Assignee: Dell Products L.P.Inventors: Yun Xi, Yu Huang Lin, Meng Meng Jiang, Wen Sen Que, Hua Shan Liang, Mu Shou Lan, Zhi Jian Weng, Lang Lin

Patent number: 11593229Abstract: Data protection methods and systems for a storage environment are provided. A first-in-first out (FIFO) structure stores a logical representation of a first storage location that retains previous data for a data container, after new data for the data container is stored at a second storage location. The FIFO structure also stores a logical representation of a file system tree structure that is stored in persistent storage, after a consistent point operation. In response to an event, the file system tree structure is selected, based on the file system tree structure being closest to a transaction. A snapshot is generated using the file system tree structure. Thereafter, the data container is restored from the snapshot or from a copy of the snapshot.Type: GrantFiled: September 23, 2020Date of Patent: February 28, 2023Assignee: NETAPP, INC.Inventors: Vikhyath Rao, Nikul Y.

Patent number: 11573846Abstract: Techniques for predicting failure mode specific reliability characteristics of tangible equipment using parametric probability models are disclosed. In some example embodiments, a computer system receives a model training configuration entered via a user interface, trains a failure curve model for a selected failure mode of a selected equipment model based on the model training configuration at a time indicated by training schedule data, and generates analytical data for the selected failure mode of the selected equipment model using the trained failure curve model. The failure mode corresponds to a specific way in which the equipment model is capable of failing. In some example embodiments, the training of the failure curve model comprises determining a shape parameter and a scale parameter for the failure curve model based on a fitting of failure event data to a continuous probability distribution, and storing the parameters for use in generating the analytical data.Type: GrantFiled: June 20, 2022Date of Patent: February 7, 2023Assignee: SAP SEInventor: Rashmi B.

Patent number: 11573872Abstract: In various examples, one or more components or regions of a processing unit—such as a processing core, and/or component thereof—may be tested for faults during deployment in the field. To perform testing while in deployment, the state of a component subject to test may be retrieved and/or stored during the test to maintain state integrity, the component may be clamped to communicatively isolate the component from other components of the processing unit, a test vector may be applied to the component, and the output of the component may be compared against an expected output to determine if any faults are present. The state of the component may be restored after testing, and the clamp removed, thereby returning the component to its operating state without a perceivable detriment to operation of the processing unit in deployment.Type: GrantFiled: December 20, 2021Date of Patent: February 7, 2023Assignee: NVIDIA CorporationInventors: Jonah Alben, Sachin Idgunji, Jue Wu, Shantanu Sarangi

Patent number: 11544165Abstract: To locate an intermittent fault in a communication structure of an aircraft comprising pieces of equipment that are interconnected by cabling forming a plurality of communication media that are shared, an analyzer retrieves an error report relating to transmission errors observed on each of said communication media, performs a count of the transmission errors, per type of error and per communication chain, computes a median of the counts for communication chains comprising the same pair of wired pieces of equipment, and when, for a communication chain, the count exceeds a threshold equal to the median plus a predefined margin, generates an alarm indicating detection of an intermittent fault in association with the communication chain that led the threshold to be exceeded. Thus, intermittent faults are easily located and repaired.Type: GrantFiled: June 24, 2020Date of Patent: January 3, 2023Assignee: AIRBUS OPERATIONS SASInventors: Philippe Passemard, Alvaro Ruiz Gallardo
