  • Patent number: 11857689
    Abstract: Described are light generating devices employing ultraviolet (UV) light emitting diodes and one or more UV active materials, such as UV reflective materials, UV scattering materials, and UV transparent materials. A UV light generation system, may include a plurality of UV light emitting diodes arranged across a surface having a diffuse UV reflective layer. The UV light generation system may be arranged to enclose a fluid pathway or may be arranged as a liner of a container or vessel for use in disinfecting, purifying, or sterilizing fluid, particles or objects in the fluid pathway, container, or vessel by exposure of the fluid, particles or objects to UV light generated by the UV light emitting diodes.
    Type: Grant
    Filed: November 2, 2022
    Date of Patent: January 2, 2024
    Assignee: W.L. Gore & Associates, Inc.

  • Publication number: 20070226976
    Abstract: An improved ultrasound transducer assembly, e.g. a thickness-mode transducer assembly includes a plurality of elements comprising piezoelectric material, and a backing material disposed adjacent to a back surface of the plurality of elements. The piezoelectric material and backing material define at least a portion of a side surface, wherein an electrically conductive material is disposed upon and in contact with at least a portion of the side surface. The elements may comprise one or a plurality of front electrodes, and one or a plurality of back electrodes, wherein the front electrode(s) is electrically interconnected to the electrically conductive material disposed on the side surface portion. In a mass processing method, a plurality of thickness-mode ultrasound probe transducer assemblies may be produced, wherein a plurality of interconnected transducer subassemblies comprising a mass backing are processed in tandem.
