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: 11958209Abstract: A delignified wood material is formed by removing substantially all of the lignin from natural wood. The resulting delignified wood retains cellulose-based lumina of the natural wood, with nanofibers of the cellulose microfibrils being substantially aligned along a common direction. The unique microstructure and composition of the delignified wood can provide advantageous thermal insulation and mechanical properties, among other advantages described herein. The thermal and mechanical properties of the delignified wood material can be tailored by pressing or densifying the delignified wood, with increased densification yielding improved strength and thermal conductivity. The chemical composition of the delignified wood also offers unique optical properties that enable passive cooling under solar illumination.Type: GrantFiled: September 14, 2018Date of Patent: April 16, 2024Assignee: UNIVERSITY OF MARYLAND, COLLEGE PARKInventors: Liangbing Hu, Tian Li, Jianwei Song, Chaoji Chen

Patent number: 11944540Abstract: Described herein are devices and methods for mitral valve repair. The devices and methods implant a plurality of distal anchors at an annulus of the mitral valve (e.g., the posterior annulus) and tension artificial chordae to pull the portion of the annulus toward an opposite edge and inward into the ventricle. This can effectively reduce the size of the orifice and increase coaptation. The delivery devices can be configured to be actuated to form a distal anchor made of a pre-formed knot. The delivery devices deliver the pre-formed knot in an elongate configuration. Actuation of the delivery device causes the pre-formed knot to transition from the elongate configuration to the deployed configuration by approximating opposite ends of a suture coupled to a coiled configuration to form one or more loops. After formation of the knot, the delivery device can be withdrawn.Type: GrantFiled: September 4, 2020Date of Patent: April 2, 2024Assignees: University of Maryland, Baltimore, Harpoon Medical, Inc.Inventors: Michael Nicholas D'ambra, Felino V.

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: 11931600Abstract: Techniques are presented for optimizing a treatment plan for charged particle therapy. The method includes obtaining medical image data voxels inside a subject in a reference frame of a radiation source that emits a beam of charged particles at multiple tracks with a controlled emitted energy at each track. Hydrogen density (HD) is determined based on the medical image data. Stopping power ratio (SPR) along a first beam having a first track and first emitted energy is calculated based on HD. A range to a Bragg peak is calculated along the first beam based on the SPR and the first emitted energy. The first beam track or the first emitted energy, or both, is modified based at least in part on the beam range to determine a second track and second emitted energy. Output data that indicates the second track and second emitted energy are sent.Type: GrantFiled: March 11, 2019Date of Patent: March 19, 2024Assignee: University Of Maryland, BaltimoreInventors: Byong Yong Yi, Ulrich Langner, Sina Mossahebi, Chaitanya Kalavagunta

Patent number: 11921113Abstract: The present invention provides for excitable molecules positioned near metallic structures, wherein the metallic structures have a particles size from about 1 nm to 1000 nm and wherein the excitable molecules have fluorescence, phosphorescence or alpha-fluorescence emissions that are altered due to positioning near the metal structures. The emission spectra are distorted on either the blue or red edges in a range from 1 to 10 nm thereby changing the color of emissions. Further, the width of the emission spectrum is modified either by narrowing or broadening depending on the material of the metallic structures and type of excitable molecule.Type: GrantFiled: July 16, 2019Date of Patent: March 5, 2024Assignee: UNIVERSITY OF MARYLAND, BALTIMORE COUNTYInventor: Chris D.

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

Patent number: 11921013Abstract: A one-dimensional (1D) and two-dimensional (2D) scan scheme for a tracking continuously scanning laser Doppler vibrometer (CSLDV) system to scan the whole surface of a rotating structure excited by a random force. A tracking CSLDV system tracks a rotating structure and sweep its laser spot on its surface. The measured response of the structure using the scan scheme of the tracking CSLDV system is considered as the response of the whole surface of the structure subject to random excitation. The measured response can be processed by operational modal analysis (OMA) methods (e.g., an improved lifting method, an improved demodulation method, an improved 2D demodulation method). Damped natural frequencies of the rotating structure are estimated from the fast Fourier transform of the measured response. Undamped full-field mode shapes are estimated by multiplying the measured response using sinusoids whose frequencies are estimated damped natural frequencies.Type: GrantFiled: October 21, 2022Date of Patent: March 5, 2024Assignee: UNIVERSITY OF MARYLAND, BALTIMORE COUNTYInventors: Weidong Zhu, Linfeng Lyu
