Abstract: Provided are adhesive-backed films and related methods useful in laser cutting a substrate protected by an adhesive-backed film. The adhesive-backed film includes a base layer comprised of a polymer and having opposing first and second major surfaces and an adhesive layer comprising a pressure-sensitive adhesive directly or indirectly coupled to the second major surface. An infrared absorber is present in one or both of the polymer and the pressure-sensitive adhesive, and the adhesive-backed film is sufficiently transparent to enable visual inspection of a surface having the adhesive-backed film disposed thereon.

Abstract: A method for coupling a tube to a tube fitting includes radially outwardly expanding a tubular compression collar from a constricted state to an expanded state, the compression collar having a throughway extending there through and being made of a resiliently flexible material. An end of the tube is inserted within the throughway of the expanded compression collar, the tube bounding a passageway. A tube fitting is inserted within the passageway of the tube. The compression collar is allowed to resiliently rebound back towards the constricted state so that the compression collar pushes the tube against the tube fitting.

Abstract: Lightguides and methods for making and using the same are disclosed. A structured layer is provided with light extractors formed on a structured surface thereof. In some cases, the structured layer is removably laminated onto a substrate to provide uniform light extraction. In some cases, indicia are cut out of the structured layer and laminated onto the substrate. In some cases, the structured surface of the structured layer is selectively filled to form a pattern for light extraction. In some cases, a tool for producing a structured layer has a region of structures selectively filled to form a pattern for light extraction on the produced structured layer.
