Publication number: 20240122507Abstract: An example method includes generating a signal correlated with blood perfusion or SpO2 of a subject at a location and orientation on a body of the subject; determining a signal quality and/or signal strength of the signal; and in dependence on the signal quality and/or signal strength, either indicating that at least one of the location or the orientation is acceptable for placement of a biosensor on the body of the subject or prompting the subject or other person to reposition the biosensor. The biosensor may be part of a chest sensor device that includes: an adhesive with a liner having pull tabs for easy removal when the chest sensor device is positioned at a desired location; a finger grip to facilitate removal of the chest sensor device from the subject after a period of use; and/or wraparound fingers to secure the chest sensor device to the adhesive.Type: ApplicationFiled: October 17, 2022Publication date: April 18, 2024Inventors: Henry Do, Harley Gordon White, Zongde Qiu, David Jonq Wang, Alexander Katsis, Thomas Dietiker

Patent number: 11718839Abstract: A composition and method for preventing and treating infections caused by enveloped viruses, such as SARS-CoV-2 virus. The invention includes compounds having a catalytic domain of a glycosidase and a binding domain that binds the compound to the surface of the targeted virus. The invention also includes a pharmaceutical formulation comprising the compound and a pharmaceutically acceptable carrier to deliver the active portion of the compound to the infecting virus within an infected human or animal. The pharmaceutical formulation can be an inhalant or a nasal spray to the infected human or animal. The invention also includes methods of using a glycosidase or the catalytic part of a glycosidase to deactivate enveloped virus by removing glycans from the viral surface protein.Type: GrantFiled: July 16, 2021Date of Patent: August 8, 2023Assignee: ILLINOIS INSTITUTE OF TECHNOLOGYInventors: Oscar Juarez, Karina Tuz, David Do Le Minh

Patent number: 8146642Abstract: A laser strikes and aseptically heats or sterilizes the end of two flexible tube ends for connection. Tube holders are pushed toward each other to bring the tube ends into contact. A weld detector checks the characteristics of the weld. A laser optics assembly may be used to chance the direction of the lacer and focus the laser at the tube ends. In addition, a crimping device is used to compress a single flexible tube for disconnection. The laser strikes the compressed area. The crimping device continues to pinch the area and forms a seal in the tube. The tube is separated into two tube segments, each segment has a sealed end.Type: GrantFiled: October 23, 2008Date of Patent: April 3, 2012Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Frank J.
