Patent number: 11963791Abstract: A method for training an algorithm for predicting a knee adduction moment (KAM) includes, while each subject walks over forceplates, capturing kinematic data, generating first ground reaction force (GRF) data, generating second GRF data, and generating reference KAM data based on the kinematic data and the first GRF data. While repeatedly training the algorithm by incrementing i by one, the method performs generating a model, which predicts reference KAM data, validating the predicted reference KAM data based on reference KAM data of the subjects other than the i-th subject, adjusting internal parameters by minimizing an error between the predicted KAM data and reference KAM data of the subjects other than the i-th subject, and producing an accuracy score for the model based on an error between the predicted reference KAM data and the reference KAM data of the i-th subject.Type: GrantFiled: January 25, 2022Date of Patent: April 23, 2024Assignee: University of Maryland, College ParkInventors: Yunjung Heo, Jumyung Um, Jae Kun Shim, Samantha Snyder, Ross Miller

Patent number: 11933747Abstract: The system for in-situ real-time measurements of microstructure properties of 3D-printing objects during 3-D printing processes. An intensive parallel X-ray beam (with an adjustable beam size) impinges on a printing object and is diffracted on a crystal lattice of the printing material. The diffracted radiation impinges on a reflector formed with an array of reflector crystals mounted on an arcuated substrate. The diffracted beams reflected from the reflector crystals correspond to the diffraction intensity peaks produced by interaction of the crystal lattice of the printing material with the impinging X-ray beam. The intensities of the diffraction peaks are observed by detectors which produce corresponding output signals, which are processed to provide critical information on the crystal phase composition, which is closely related to the defects and performance of the printing objects.Type: GrantFiled: June 28, 2018Date of Patent: March 19, 2024Assignees: University of Maryland, College Park, Advanced Analyzer Labs., Inc.Inventors: Peter Zavalij, Huapeng Huang, Lester W.

Patent number: 11922110Abstract: Systems and techniques for generating responsive documents are described. Digital content is organized into a structure that defines how content is presented when a document is displayed by a computing device. To generate the responsive document, relationships are defined among different digital content objects, such as groups of content objects to be presented together and content objects that are to be presented as alternatives of one another. Responsive patterns are assigned to grouped content objects, where each responsive pattern defines different layout configurations for displaying grouped content objects based on computing device display characteristics. In some implementations, multiple responsive patterns are assigned to a single content group and individual responsive patterns are associated with activation ranges for display characteristics that activate the responsive pattern.Type: GrantFiled: November 24, 2021Date of Patent: March 5, 2024Assignees: Adobe Inc., University of Maryland, College ParkInventors: Vlad Ion Morariu, Yuexi Chen, Christopher Alan Tensmeyer, Zhicheng Liu, Lars Niklas Emanuel Elmqvist
