Publication number: 20240127878Abstract: Memory devices and methods of operating memory devices in which refresh management operations can be scheduled on an as-needed basis for those memory portions where activity (e.g., activations in excess of a predetermined threshold) warrants a refresh management operation are disclosed. In one embodiment, an apparatus comprises a memory including a memory location, and circuitry configured to determine a count corresponding to a number of activations at the memory location, to schedule a refresh management operation for the memory location in response to the count exceeding a first predetermined threshold, and to decrease the count by an amount corresponding to the first predetermined threshold in response to executing the scheduled refresh management operation. The circuitry may be further configured to disallow, in response to determining that the count has reached a maximum permitted value, further activations at the memory location until after the count has been decreased.Type: ApplicationFiled: October 27, 2023Publication date: April 18, 2024Inventors: Timothy B. Cowles, Dean D. Gans, Jiyun Li, Nathaniel J. Meier, Randall J. Rooney

Patent number: 11924305Abstract: A computer-implemented method, an apparatus, and a computer program product for edge node autonomy. For a first edge node of a plurality of edge nodes in a federation in a distributed computing framework, one or more processors receive a request to be sent to a central node in the distributed computing framework. The one or more processors determine whether the federation is connected to the central node. In response to determining that the federation is not connected to the central node, the one or more processors determine whether a controller capable of processing the request is available in the federation. In response to determining that the controller capable of processing the request is available in the federation, the one or more processors notify the controller to process the request.Type: GrantFiled: June 29, 2022Date of Patent: March 5, 2024Assignee: International Business Machines CorporationInventors: Peng Li, Guang Ya Liu, Xun Pan, Hai Hui Wang, Xiang Zhen Gan

Patent number: 10877053Abstract: A method of determining an analyte concentration in a sample by a sensor is disclosed. The method includes analyzing a sample signal generated by the sensor for an analyte being measured. If the sample signal is normal, the method includes comparing the sample signal with a first reference signal of a reference solution measured prior to measuring the sample in order to determine the analyte concentration. If the sample signal is abnormal, the method includes comparing the sample signal with a calculated reference signal point obtained by interpolation between the first reference signal and a second reference signal of the same reference solution measured after measuring the sample. Various methods of determining and handling errors based on signal patterns are also disclosed.Type: GrantFiled: March 5, 2018Date of Patent: December 29, 2020Assignee: Roche Diagnostics Operations, Inc.Inventor: Li Gan
