Patent number: 11642067Abstract: Examples include receiving and storing samples of target frequency bands filtered from EEG measurement of a subject's brain waves in an NFB training session. In an example, upon storing a time window of the samples, unsupervised adaptive adjusting an NFB reward threshold is automatic. The adjusting includes, in examples, determining neuromarker values in the time window, which indicate peak values of the target frequency bands over the time window. The adjusting computes the mean value of the neuromarker values and, utilizing same, automatically proceeds to unsupervised computing an adaptive adjusted reward threshold. The unsupervised computing, in examples, includes a multiplication product of a reward threshold adjustment factor, a training protocol value, and the computed mean value of the neuromarker values. Examples proceed to communicating the adaptive adjusted reward threshold to a controller for threshold based feedback reward to the NBF subject.Type: GrantFiled: August 15, 2022Date of Patent: May 9, 2023Assignee: King Abdulaziz UniversityInventors: Ubaid M.

Patent number: 10619933Abstract: A syngas cooler system includes a pressure vessel, a conduit, a plenum, a plenum, a conduit, and a bellows assembly. The pressure vessel includes a throat and a dome adjacent to the throat. The throat includes an area of excess heat, and the dome includes an area of deficient heat. The plenum extends between the throat and the bellows assembly. The bellows assembly is coupled at least partially within the dome. The conduit is coupled to the plenum for channeling a flow of purge fluid from external to the pressure vessel into the plenum such that purge fluid transfers heat from the area of excess heat into the area of deficient heat to facilitate reducing temperature differential stresses within the dome and the pressure vessel.Type: GrantFiled: July 26, 2017Date of Patent: April 14, 2020Assignee: Air Products and Chemicals, Inc.Inventors: James Michael Storey, Alex Clinton Solomon, Benjamin Campbell Steinhaus, Judeth Brannon Corry, Steven Craig Russell, Robert Henri Gauthier, Yasir Hafeez Abbasi, Lien-Yan Chen

Patent number: 9739539Abstract: A system for preheating a pressure vessel includes a throat including an area of excess heat and a dome having an area of deficient heat. The throat includes a conduit extending from a pressure vessel opening to the pressure vessel interior. A plenum is defined between the throat and a seal within the dome. The throat extends from the dome toward a dome floor. The floor is substantially perpendicular to the throat. A conduit is coupled to the plenum and channels a flow of purge fluid into the plenum wherein heat from the throat is transferred to the flow of purge fluid and carried by the flow of purge fluid into the area of deficient heat via a gap defined between the seal and the floor such that the flow of purge fluid reduces temperature differential stresses within the pressure vessel and purges the area of deficient heat.Type: GrantFiled: May 16, 2014Date of Patent: August 22, 2017Assignee: General Electric CompanyInventors: James Michael Storey, Alex Clinton Solomon, Benjamin Campbell Steinhaus, Judeth Brannon Corry, Steven Craig Russell, Robert Henri Gauthier, Yasir Hafeez Abbasi, Lien-Yan Chen
