Patent number: 11457691Abstract: A method, computer program product, and a system where a processor(s), in a computing environment comprised of multiple containers comprising modules, includes a processor(s) continuously obtaining pressure data from pressure sensors embedded in electrostatic dissipative (ESD) footwear. The processor(s) determines that the obtained pressure data indicates a pressure level of a pre-determined threshold and the given threshold is sustained for a pre-determined interval of time in some of the items. The processor(s) accesses one or more voltage sensors embedded in each item of the items and obtains voltage data by utilizing an ESD floor that the items are in contact with as a ground reference. The processor(s) validates functionality of some of the items and functionality of the ESD floor, based on monitoring the voltage data from the one or more voltage sensors.Type: GrantFiled: December 30, 2020Date of Patent: October 4, 2022Assignee: International Business Machines CorporationInventors: Ho-Yiu Lam, John Thomas Kinnear, Jr., Sia Kai Julian Tan

Patent number: 11257001Abstract: An enhanced prediction model utilizing product life cycle segmentation and historic prediction data for generating more accurate future failure rates. Input data is segmented into groups based on failure modes of a corresponding life cycle. A prediction model such as Weibull analysis is implemented for each segmented group. Historical prediction data is also segmented into groups. Prediction parameters for each group of segmented historical prediction data are compared with one another and the comparisons are then used to adjust the prediction parameters generated from the segmented groups of input data. Updated parameters for the input data are then output thereby generating a new future failure rate.Type: GrantFiled: October 9, 2018Date of Patent: February 22, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lu Liu, Sia Kai Julian Tan, Kevin A. Dore, II, Steven Hurley, Jr.
