Patent number: 11119761Abstract: A computer-implemented method, system and computer program product for identifying implicit dependencies between code artifacts. Co-defect association rules between code artifacts are generated, where such co-defect association rules include a prediction of how likely there will be a defect in a code artifact when there is a defect in an associated code artifact. After detecting a defect in a first code artifact, the co-defect association rules are reviewed to identify any code artifacts associated with the first code artifact. If there is a code artifact associated with the first code artifact, and if the probability of the associated code artifact being defected when the first code artifact is defected exceeds a threshold value, then a recommendation is made to the user to review not only the first code artifact that was defected but also its associated code artifact for a potential defect.Type: GrantFiled: August 12, 2019Date of Patent: September 14, 2021Assignee: International Business Machines CorporationInventors: Bo Zhang, Xianjun Zhu, Bradley C. Herrin, Liwei Wang

Patent number: 11022792Abstract: Aspects of the embodiments are directed to coupling a permanent magnet (PM) with a microelectromechanical systems (MEMS) device. In embodiments, an adhesive, such as an epoxy or resin or other adhesive material, can be used to move the PM towards the MEMS device to magnetically couple the PM to the MEMS device. In embodiments, an adhesive that is configured to shrink up on curing can be applied (e.g., using a pick and place tool) to a location between the MEMS device and the PM. As a result of curing, the adhesive can pull the PM towards the MEMS device. In embodiments, an adhesive that is configured to expand as a result of curing can be applied to a location between the PM and a sidewall of the chassis. As a result of curing, the adhesive can push the PM towards the MEMS device. The adhesive can also secure the PM in place.Type: GrantFiled: December 27, 2016Date of Patent: June 1, 2021Assignee: Intel CorporationInventors: Kyle Yazzie, Anna M.
