Patent number: 12280429Abstract: A system and method of additive manufacturing is disclosed herein which when run or performed form a product with a powder-based additive manufacturing device by adding sequential layers of material on top of one another. As each sequential layer of material is added, the system and method can include monitoring the sequential layer with a defect analysis subsystem to detect whether the sequential layer has any defects. For a detected defect, it can be determined whether defect correction is required. For a required defect correction, one or more correction parameters for the required defect correction can be identified; and a correction command including the one or more correction parameters can be sent to the additive manufacturing device, the correction command causing the additive manufacturing device to help correct the detected defect in the sequential layer according to the correction parameters prior to moving on to a next sequential layer.Type: GrantFiled: August 15, 2023Date of Patent: April 22, 2025Assignee: Sentient Science CorporationInventors: Jingfu Liu, Behrooz Jalalahmadi, Ziye Liu, Andrew Vechart, Xiawa Wu

Patent number: 12135009Abstract: A method and a system for estimating remaining components life of an operational wind turbine from actual wind turbine operation conditions after it was commissioned, using a data acquisition module configured to measure real historical data of said operational wind turbine, and an additional state detection unit configured to identify historical states of operation. The method comprises extracting historical data from the data acquisition module at time intervals, identify operational states of the wind turbine, validate the identified operational states and identify uncertain data that do not match. Next, simulate a turbine model for each operational state identified and wind condition thereof at each time interval, and calculate a fatigue equivalent load for each operational state and wind condition.Type: GrantFiled: April 1, 2019Date of Patent: November 5, 2024Assignees: ACCIONA GENERACIÓN RENOVABLE, S.A., SENTIENT SCIENCE CORPORATIONInventors: Adrijan Ribaric, Juan Gallego-Calderon, Mercedes Irujo Espinosa De Monteros

Patent number: 11835030Abstract: Embodiments disclosed herein may include methods, systems, and tangible, non-transient, computer-readable media having instructions thereupon for determining a damage state of a wind turbine gearbox. A method performed, executed on a processor of a system, or implemented by a processor as instructions, may comprise producing a damage state diagnostic, producing a damage progression model for the wind turbine gearbox using operational data and a state transition function, and combining the damage state diagnostic with the damage progression model using a hybrid prognostics model to produce a probability distribution of a current damage state estimate.Type: GrantFiled: December 31, 2019Date of Patent: December 5, 2023Assignees: Sentient Science Corporation, Acciona EnergiaInventors: Vijayant Kumar, Nathan Bolander, Gunther Auer, Inigo Zalacain, Mercedes Irujo, Enrique Iriarte

Patent number: 11238196Abstract: A system and method for determining surface contact fatigue life may use a finite element method to determine when components, such as a power transmission component, may fail in operation. The method may generate a finite element model based on the material parameters related to a power transmission component, generate a surface pressure time history for a loading event based on one or more loading parameters, determine, based on the surface pressure time history for a loading event, a finite element solution that describes stress in the grain structure, calculate damage in the finite element solution using a damage model, and determine whether a damage threshold is exceeded.Type: GrantFiled: November 12, 2019Date of Patent: February 1, 2022Assignee: Sentient Science CorporationInventors: Nathan Bolander, Rajasekhar V.
