Patent number: 12236363Abstract: Described herein are systems and methods for providing a natural language comprehension system that employs a two-stage process for machine comprehension of text. The first stage indicates words in one or more text passages that potentially answer a question. The first stage outputs a set of candidate answers for the question, along with a first probability of correctness for each candidate answer. The second stage forms one or more hypotheses by inserting each candidate answer into the question and determines whether a sematic relationship exists between each hypothesis and each sentence in the text. The second processing circuitry generates a second probability of correctness for each candidate answer and combines the first probability with the second probability to produce a score that is used to rank the candidate answers. The candidate answer with the highest score is selected as a predicted answer.Type: GrantFiled: June 24, 2022Date of Patent: February 25, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Adam Trischler, Philip Bachman, Xingdi Yuan, Alessandro Sordoni, Zheng Ye

Patent number: 12067490Abstract: Examples of the present disclosure provide systems and methods relating to a machine comprehension test with a learning-based approach, harnessing neural networks arranged in a parallel hierarchy. This parallel hierarchy enables the model to compare the passage, question, and answer from a variety of perspectives, as opposed to using a manually designed set of features. Perspectives may range from the word level to sentence fragments to sequences of sentences, and networks operate on word-embedding representations of text. A training methodology for small data is also provided.Type: GrantFiled: October 17, 2022Date of Patent: August 20, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Adam Trischler, Zheng Ye, Xingdi Yuan, Philip Bachman

Patent number: 12057796Abstract: Systems and methods for monitoring and suppressing a back EMF generated by an ESP motor when the ESP system is moved in a well. Embodiments provide both electrical braking to reduce the rotation of the motor (and corresponding back EMF) and warnings to alert users to hazardous conditions caused by the back EMF. One embodiment includes an ESP system having a permanent magnet motor, a back EMF safety system, and a power cable connected between them. The proximal ends of the cable's conductors are connected terminals of the back EMF safety system, which has switches that are closed to short circuit the conductors so that back EMF currents from rotation of the motor induce electrical braking in the motor. Currents and phase-to-phase voltages on the conductors are monitored to detect overcurrent and overvoltage conditions that may trigger alarms or other actions.Type: GrantFiled: January 18, 2022Date of Patent: August 6, 2024Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Yong Li, Zheng Ye, Charles Collins

Patent number: 12038013Abstract: An electrical submersible well pump assembly has shaft couplings. One of the couplings has a lower hub that rotates in unison with the motor shaft and an upper hub that rotates in unison with the pump shaft. A helical spring clutch engages both hubs when the motor shaft is being driven by the motor. Ceasing driving rotation of the motor shaft causes the spring clutch to disengage from the upper hub, enabling the pump shaft to rotate the upper hub without rotating the lower hub.Type: GrantFiled: July 27, 2022Date of Patent: July 16, 2024Assignee: BAKER HUGHES OILFIELD OPERATIONS, LLCInventors: Zheng Ye, Randal Perisho

Patent number: 11795951Abstract: A submersible well pump has a rotatable drive shaft extending through pump stages. Each of the stages has a diffuser, an impeller and a bushing fixed for non-rotation in the diffuser. A thrust member has a lower side in sliding rotating engagement with the upward facing surface of the bushing. The bushing and the thrust member are of a harder material than the diffuser and the impeller. A drive member of a softer material than the thrust member is in engagement with the thrust member and has a drive member bore through which the shaft extends. A key extends through the shaft groove, the impeller groove and the drive member groove to cause the impeller and thrust member to rotate with the shaft.Type: GrantFiled: May 4, 2021Date of Patent: October 24, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS, LLCInventors: Zheng Ye, Ignacio Martinez, Risa Rutter, Mark Paquette

Patent number: 11795962Abstract: An electrical submersible well pump assembly (ESP) has a spring brake having helical turns mounted between the shaft and one of the housings. The spring brake allows free rotation of the shaft in a driving direction and stops the shaft from rotating in a reverse direction. The spring brake may have one end be affixed to the housing to rotate in unison in both directions. Alternately, the spring brake may have one end affixed to the shaft for rotation with the shaft. Further, the spring brake could be free of being connected to either the shaft or the housing. A shear member may be mounted between the shaft and the housing to prevent any rotation of the shaft during run-in.Type: GrantFiled: April 16, 2021Date of Patent: October 24, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS, LLCInventors: Randal Perisho, Zheng Ye

Publication number: 20230070148Abstract: An auto-engageable coupling is disclosed for use in a pumping system that includes an electric motor and a pump driven by the electric motor. The auto-engageable coupling permits the transfer of torque from the motor to the pump, but prevents the pump from applying torque to the motor. In some embodiments, the auto-engageable coupling includes a drive plate connected to a motor shaft and a reaction plate connected to an output shaft. The drive plate and reaction plate are only coupled together to transmit torque from the motor to the pump when the motor is activated and rotating in a first, intended direction. When the motor is not activated and the pump is forced to rotate in a first direction, the drive plate and the reaction plate are disengaged to prevent the delivery of torque from the pump to the motor.Type: ApplicationFiled: September 6, 2022Publication date: March 9, 2023Applicant: Baker Hughes Oilfield Operations LLCInventors: Zheng Ye, David Tanner
