Patent number: 11922123Abstract: Techniques for automatically switching between chatbot skills in the same domain. In one particular aspect, a method is provided that includes receiving an utterance from a user within a chatbot session, where a current skill context is a first skill and a current group context is a first group, inputting the utterance into a candidate skills model for the first group, obtaining, using the candidate skills model, a ranking of skills within the first group, determining, based on the ranking of skills, a second skill is a highest ranked skill, changing the current skill context of the chatbot session to the second skill, inputting the utterance into a candidate flows model for the second skill, obtaining, using the candidate flows model, a ranking of intents within the second skill that match the utterance, and determining, based on the ranking of intents, an intent that is a highest ranked intent.Type: GrantFiled: September 30, 2021Date of Patent: March 5, 2024Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Vishal Vishnoi, Xin Xu, Elias Luqman Jalaluddin, Srinivasa Phani Kumar Gadde, Crystal C.

Publication number: 20210252151Abstract: The blood-brain barrier (BBB) excludes most drugs and poses a significant challenge to treat brain diseases. Current methods for BBB opening yield modest outcomes in clinical applications due to safety and toxicity. This disclosure relates to methods of optically opening the BBB by laser excitation of tight-junction targeted nanoparticles to induce BBB transient opening. The excitation of plasmonic nanoparticles produces localized effects such as nanoscale heating and photomechanical force leading to BBB transiently opening to allow macromolecules across it. The safe and predictable platform for brain drug delivery will improve therapies for brain disease such as cancers, infections and neurologic disorders.Type: ApplicationFiled: June 14, 2019Publication date: August 19, 2021Applicant: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Zhenpeng QIN, Xiaoqing LI, Xiuying LI, Shashank SIRSI, Heather HAYENGA, Edward PAN, Robert BACHOO

Publication number: 20130272785Abstract: A system includes a rotary machine. The rotary machine has a spline joint coupling first and second rotary components. The spline joint has a male spline portion and a female spline portion. The male spline portion includes a first plurality of spline teeth spaced circumferentially apart from one another about a longitudinal axis of the spline joint. The female spline portion includes a second plurality of spline teeth spaced circumferentially apart from one another about the longitudinal axis of the spline joint. The first plurality of spline teeth and the second plurality of spline teeth extend axially along the longitudinal axis. At least one tooth of the first or second plurality of spline teeth has at least one groove extending crosswise relative to the longitudinal axis. The at least one groove is disposed at an intermediate axial position between opposite axial ends of the at least one tooth.Type: ApplicationFiled: April 11, 2012Publication date: October 17, 2013Applicant: General Electric CompanyInventor: Edward Pan
