  • Publication number: 20240122507
    Abstract: 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.

  • Patent number: 11718839
    Abstract: 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.

  • Publication number: 20160056061
    Abstract: Embodiments of the present invention generally relate to a method and apparatus for ex-situ cleaning of a chamber component. More particularly, embodiments of the present invention generally relate to a method and apparatus for endpoint detection during ex-situ cleaning of a chamber component used in a semiconductor processing chamber. In one embodiment, a system for cleaning parts disposed in a liner with a cleaning fluid is provided. The system comprises a portable cart, a liquid particle counter (LPC) carried by the portable cart, the LPC configured for detachable coupling to a fluid outlet port formed through the liner, the LPC operable to sample rinsate solution exiting the line, and a pump carried by the portable cart and configured for fluid coupling to the liner in a detachable manner, the pump operable to recirculate rinsate solution through the liner.

  • Patent number: 8146642
    Abstract: 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.
