Abstract: An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.

Abstract: Medical adhesive articles include a layer of adhesive and a modified substrate layer where the layer has a plurality of cuts arrayed in a pattern that may be random or the pattern can be arrayed along at least one axis. The cuts are gaps, but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, and at least some of the cuts become gaps that are visible to the naked eye and form apertures when the adhesive article is in a stressed state. The adhesive articles can be used to adhere a medical device to skin.

Abstract: A method for filtering airborne particulates is described. The method includes providing an exhaust hood, and the exhaust hood defines an intake and the exhaust hood being adapted to receive airborne particulates via the intake. The method also includes conveying a portion of a filter media from a media source area to an active media area, transferring the portion of the filter media from the active media area to a media discard area, the media discard area and the media source area being disposed on substantially opposed sides of the active media area, and severing the portion of the filter media in the media discard area from a remainder of the filter media.

Abstract: Filter assemblies are described. In particular, a filter securement assembly for receiving and retaining a filter media in an exhaust hood is disclosed, the filter securement assembly being releasably securable to the exhaust hood, includes a filter frame, a cover and a face forming a portion of the cover, the face defining a plurality of apertures therethrough, the apertures forming at least 50% of a face surface area.
