Patent number: 11957447Abstract: Systems and devices for detecting and characterizing stratified fluid and/or aerosol particles and droplets, and methods of use thereof to, for example, diagnose and prognose respiratory diseases and disorders are provided. The systems typically include optoelectronic sensors for detecting foreign particles like bacteria and pollutants in the air (i.e., the aerosol) based on light scattering. Information collected in this way can be used to, for example, detect or identify respiratory maladies and determine the effectiveness of methods of treatment thereof.Type: GrantFiled: June 18, 2020Date of Patent: April 16, 2024Assignee: UNIVERSITY OF GEORGIA RESEARCH FOUNDATION, INC.Inventors: Venkata Sreerama Narasimha Rao Tatavarti, Ramana Murthy Pidaparti, Sanjay Sarma Oruganti Venkata

Patent number: 11901476Abstract: The present invention utilizes epitaxial lift-off in which a sacrificial layer is included in the epitaxial growth between the substrate and a thin film III-V compound solar cell. To provide support for the thin film III-V compound solar cell in absence of the substrate, a backing layer is applied to a surface of the thin film III-V compound solar cell before it is separated from the substrate. To separate the thin film III-V compound solar cell from the substrate, the sacrificial layer is removed as part of the epitaxial lift-off. Once the substrate is separated from the thin film III-V compound solar cell, the substrate may then be reused in the formation of another thin film III-V compound solar cell.Type: GrantFiled: February 8, 2021Date of Patent: February 13, 2024Assignee: MICROLINK DEVICES, INC.Inventors: Noren Pan, Glen Hillier, Duy Phach Vu, Rao Tatavarti, Christopher Youtsey, David McCallum, Genevieve Martin

Publication number: 20230174254Abstract: Systems and methods are presented including solar cells or solar sheets having textured coversheets that provide increased light collection efficiency. Some embodiments include a textured solar sheet configured for installation on a surface of a UAV or on a surface of a component of a UAV. The textured solar sheet includes a plurality of solar cells and a polymer layer to which the plurality of solar cells are attached. Some embodiments include a kit for supplying solar power in a battery-powered or fuel cell powered unmanned aerial vehicle (UAV) by incorporating flexible, textured solar cells into a component of a UAV, affixing flexible, textured solar cells to a surface of a UAV, or affixing flexible, textured solar cells to a surface of a component of a UAV. The kit also includes a power conditioning system configured to operate the solar cells within a desired power range and configured to provide power having a voltage compatible with an electrical system of the UAV.Type: ApplicationFiled: October 7, 2022Publication date: June 8, 2023Inventors: Christopher Youtsey, Mark Osowski, Rao Tatavarti
