Patent number: 12171885Abstract: One of the significant challenges to translation of intravenously administered nanomaterials has been complement-mediated infusion reactions which can be lethal. Slow infusions can reduce infusion reactions, but slow infusions are not always possible in applications like controlling bleeding following trauma. Nanocapsules based on polyurethane are introduced as candidates that do not substantially activate complement protein C5a and the PEGylation and functionalization of the nanocapsules with the GRGDS peptide to create a new class of hemostatic nanomaterials is disclosed. Advantageously, the nanocapsules substantially avoid complement-mediated infusion reactions, promote faster clotting than controls, maintain maximum clot firmness, and do not activate pro-inflammatory cytokines.Type: GrantFiled: July 15, 2022Date of Patent: December 24, 2024Assignee: UNIVERSITY OF MARYLAND, BALTIMORE COUNTYInventors: Erin Lavik, Nuzhat Maisha

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

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: 11859716Abstract: A tidal current energy converter including an infinitely variable transmission (IVT) control system and a hybrid vertical axis wind (or water) turbine (VAWTs) apparatus. The hybrid VAWT apparatus includes a modified-Savonius (MS) rotor in the central region and a straight bladed H-type Darrieus rotor in the surrounding annular region. The IVT control system includes a nonlinear closed-loop control combined with an integral time-delay feedback control to adjust a speed ratio of the IVT. A speed ratio control for an IVT system involves a forward speed controller and/or a crank length controller for different speed ranges. The time-delay control is designed to reduce speed fluctuations of the output speed of an IVT with an accurate speed ratio. The speed ratio of an IVT with the disclosed control strategy can achieve an excellent tracking response for the desired constant output speed and reduce speed fluctuations of the output speed of an IVT by the time-delay feedback control.Type: GrantFiled: April 19, 2022Date of Patent: January 2, 2024Assignee: University of Maryland, Baltimore CountyInventors: Weidong Zhu, Gang Li, Meilin Yu, Xuefeng Wang
