  • Publication number: 20200341173
    Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between a light input surface and a light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, the alternating transmissive regions and absorptive regions have a transmission as measured with a spectrophotometer at a viewing angle of 0 degrees of at least 35, 40, 45, or 50% for a wavelength of the range 320-400 nm (UV) and/or at least 65, 70, 75, or 80% for a wavelength of the range 700-1400 nm (NIR). In another embodiment, the absorptive regions block light at the light input surface and light output surface and the maximum surface area that is blocked is less than 20% of the total alternating transmissive regions and absorptive regions. Also described are various optical communication systems comprising the light control films described herein and methods.

  • Publication number: 20200326118
    Abstract: A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.

  • Publication number: 20200316239
    Abstract: A system and methods for sterilizing and drying contaminated articles, particularly medical articles, and more particularly the hollow internal areas of medical instruments or lumens of medical endoscopes. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power connected to the plasma generator applies an electrode energy density between the electrode and the shield. A source of a sterilizing gas precursor provides a flow of the sterilizing gas precursor through the plasma generator to generate a plasma, thereby forming a sterilizing gas including acidic and/or oxidizing species. The contaminated article is exposed to the sterilizing gas for a time sufficient to achieve a desired degree of sterilization. A turbulent flow of a drying gas is used to dry the contaminated article alternately with the exposure of the contaminated article to the sterilizing gas.

  • Patent number: 10378813
    Abstract: A fluid control film is provided that includes fluid control channels extending along a channel longitudinal axis. Each of the fluid control channels has a surface and is configured to allow capillary movement of liquid in the channels. The fluid control film further includes a hydrophilic surface treatment covalently bonded to at least a portion of the surface of the fluid control channels. The fluid control film exhibits a capillary rise percent recovery of at least ten percent. Typically, the hydrophilic surface treatment includes functional groups selected from a non-zwitterionic sulfonate, a non-zwitterionic carboxylate, a zwitterionic sulfonate, a zwitterionic carboxylate, a zwitterionic phosphate, a zwitterionic phosphonic acid, and/or a zwitterionic phosphonate. A process for forming a fluid control film is also provided.

  • Publication number: 20190134243
    Abstract: A system and methods for sterilizing or disinfecting articles, particularly the hollow internal areas of medical instruments are disclosed. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power is connected to the plasma generator for applying an electron energy density between the electrode and the shield. A source of gas comprising water vapor, oxygen and nitrogen provides a flow of gas between the electrode and the shield, to form a plasma containing acidic and/or oxidizing species. In the exemplary system, the temperature at the shield's surface is <150° C. when the electron energy density is >0.05 eV/molecule of the gas. Also disclosed is a method for disinfecting an article contaminated with a bio-film or spores, by exposing the contaminated article to the plasma for an exposure time sufficient to achieve at least 2-log10 reduction in colony forming units.
