Patent number: 11944390Abstract: Systems and methods are provided in which an intraoperative video feed is augmented with one or more virtual display features based on a detected orientation and position of the tracked medical instrument. In some example embodiments, the virtual display features may be employed to represent, in an augmented video feed, information associated with a previously-detected intraoperative position and orientation of the tracked medical instrument. The virtual display element may be employed, for example, to facilitate the alignment of an untracked medical instrument with a previously determined intraoperative position and orientation of the tracked medical instrument. In other example embodiments, the virtual display element may be dynamically displayed in a fixed spatial relationship relative to the tracked medical instrument.Type: GrantFiled: April 8, 2019Date of Patent: April 2, 2024Assignee: 7D Surgical ULCInventors: Adrian Mariampillai, Victor X. D. Yang, Kenneth Kuei-Ching Lee, Michael K. K. Leung, Beau Anthony Standish

Publication number: 20240024033Abstract: Systems and methods are provided that facilitate an intraoperative assessment of registration associated with a trackable reference frame. An initial position of the landmark is identified and an initial position and orientation of the trackable reference frame is determined. The position and orientation of the trackable reference frame is subsequently trance and estimated updated position of the landmark is determined by maintaining a fixed three-dimensional offset between the landmark and the trackable frame of reference. An annotation indicating the estimated updated position of the landmark is displayed, such as within an intraoperative image acquired by a camera having a known spatial relationship with the tracking system. A user may visually observe a registration error by observing a lack of spatial concordance between the actual location of the landmark the estimated updated location as indicated by the annotation. The annotation may be generated based on previously acquired surface data.Type: ApplicationFiled: August 19, 2021Publication date: January 25, 2024Inventors: THOMAS ANTHONY WELLS-QUINN, ADRIAN MARIAMPILLAI, MICHELLE MAY SEE LEUNG, KENNETH KUEI-CHING LEE, JULIA MARIE PRINCE, MICHAEL K.K.

Patent number: 11663402Abstract: An approach for a fast and accurate word embedding model, “desc2vec,” for out-of-dictionary (OOD) words with a model learning from the dictionary descriptions of the word is disclosed. The approach includes determining that a target text element is not in a set of reference text elements, information describing the target text element is obtained. The information comprises a set of descriptive text elements. A set of vectorized representations for the set of descriptive text elements is determined. A target vectorized representation for the target text element is determined based on the set of vectorized representations using a machine learning model. The machine learning model is trained to represent a predetermined association between the set of vectorized representations for the set of descriptive text elements describing the target text element and the target vectorized representation.Type: GrantFiled: July 21, 2020Date of Patent: May 30, 2023Assignee: International Business Machines CorporationInventors: Chao-Min Chang, Kuei-Ching Lee, Ci-Hao Wu, Chia-Heng Lin

Patent number: 11017083Abstract: Provided are systems, methods, and media for multiphase graph partitioning for malware entity detection. An example method includes receiving an input string associated with the malware entity. A determination is made as to whether the input string includes a symbolic word, a non-symbolic word, a symbolic phrase, or a non-symbolic phrase. A branching graph is formed based on a combination of the input string and a plurality of stored strings that are each associated with the malware entity to determine whether the input string is a valid detection name of the malware entity, in which the branching graph is formed by at least performing a first graph partitioning stage and a second graph partitioning stage. The input string is then labeled based on the formed branching graph and then outputted to a malware detection engine.Type: GrantFiled: October 17, 2018Date of Patent: May 25, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ci-Hao Wu, Ying-Chen Yu, June-Ray Lin, Hsieh-Lung Yang, Chen-Yu Huang, Chia-Heng Lin, Kuei-Ching Lee

Patent number: 10973581Abstract: Disclosed are systems and methods for obtaining a structured light reconstruction using a hybrid spatio-temporal pattern sequence projected on a surface. The method includes projecting a structured light pattern, such as a binary de Bruijn sequence, onto a 3D surface and acquiring an image set of at least a portion of this projected sequence with a camera system, and projecting a binary edge detection pattern onto the portion of the surface and acquiring an image set of the same portion of the projected binary pattern. The acquired image set of the binary pattern is processed to determine edge locations therein, and then employed to identify the locations of pattern edges within the acquired image set of the structured light pattern. The detected edges of the structured light pattern images are employed to decode the structured light pattern and calculate a disparity map, which is used to reconstruct the 3D surface.Type: GrantFiled: June 16, 2017Date of Patent: April 13, 2021Assignee: 7D SURGICAL INC.Inventors: Adrian Mariampillai, Kenneth Kuei-Ching Lee, Michael Leung, Peter Siegler, Beau Anthony Standish, Victor X.

Publication number: 20160158886Abstract: The present disclosure relates to the field of laser induced modification and processing of materials. Modification is achieved by confining laser-material interaction within an array of narrow zones characterizing an optical interference profile. Disclosed is a method of laser induced modification of a material comprising applying at least one laser pulse to the material, the at least one laser pulse being incident on the first interface of the material, wherein the material is selected on the basis that it can support an optical interference pattern such that a thin volume at a site of at least one intensity maxima of the optical interference pattern is characterized by a laser intensity above a threshold value to responsively produce the laser induced modification of the material at a location relative to the first interface.Type: ApplicationFiled: July 22, 2014Publication date: June 9, 2016Inventors: Kitty KUMAR, Kenneth Kuei-Ching LEE, Jun NOGAMI, Peter R.
