In-situ polymerized polymer film facilitates improved paint film appliques with reduced defects. The paint film appliques comprise the in-situ polymerized polymer film as a carrier layer. The carrier layer is colored and, preferably defect-free.

There is described a contact lens package containing a bowl for holding a contact lens and a flange around the bowl which may be made from a different polymer material than the bowl. The packages comprise at least one interface tab with at least one slot so that the second polymer material forming the flange can encapsulate the tab providing a mechanical interlock displaying good flexural strength.

A catheter for delivering fluids includes a hollow tube having a proximal section, a distal section, and an elongated lumen that extends through the proximal and distal sections of the hollow tube. One or more fluid openings are formed in the distal section of the hollow tube, which are in fluid communication with the elongated lumen of the hollow tube. A visible marker collar is secured to an outer surface of the hollow tube and is located at a junction of the proximal and distal sections of the hollow tube. A visible marker filament is disposed within the elongated lumen of the hollow tube and extends between the junction of the proximal and distal sections of the hollow tube and a distal end of the hollow tube. The visible markers are used to identify a soaker region of the catheter used to infuse fluids or drain fluids from a patient.

Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. Formation of printed objects having various colors may sometimes be desirable. Thermoplastic particulates incorporating a color-changing material capable of forming different colors under specified activation conditions may impart different colors to a printed object. Such particulate compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer and a color-changing material associated with the thermoplastic particulates, wherein the color-changing material is photochromic and thermochromic. Conjugated diynes, such as 10,12-pentacosadiynoic acid or a derivative thereof, may be particularly suitable color-changing materials having photochromic and thermochromic properties for forming a range of colors upon a printed object. Nanoparticles, particularly silica nanoparticles, associated with an outer surface of the thermoplastic particulates may enhance the brightness of the color obtained under various activation conditions and afford coloration permanence.

A photochromic polyurethane laminate that is constructed to solve certain manufacturing difficulties involved in the production of plastic photochromic lenses is disclosed. The photochromic laminate includes at least two layers of a resinous material and a photochromic polyurethane layer that is interspersed between the two resinous layers and which contains photochromic compounds. The polyurethane layer is formed by curing a mixture of a solid thermoplastic polyurethane, at least one isocyanate prepolymer, at least one photochromic compound, and a stabilizing system.

The present disclosure relates to a battery module that includes a housing having a first protruding shelf along a first perimeter of the housing, a second protruding shelf along a second perimeter of the housing, where the first and second protruding shelves each include an absorptive material configured to absorb a first laser emission. The battery module also includes an electronics compartment cover configured to be coupled to the housing via a first laser weld, and a cell receptacle region cover configured to be coupled to the housing via a second laser weld. The electronics compartment cover has a first transparent material configured to transmit the first laser emission toward the first protruding shelf and the cell receptacle region cover has a second transparent material configured to transmit the first laser emission or a second laser emission toward the second protruding shelf.

A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

A heat transferable label component for a garment or other clothing item or article is disclosed which is preferably produced using all digitally controlled manufacturing methods. The label component comprises a carrier layer, a release layer, an optional primer layer, a color design layer, a transition layer and at least one adhesive layer. The color design layer displays an image on the label, and the transition layer fixates the image and renders it wash and/or wear resistant. The at least one adhesive layer is positioned on the transition layer, and is preferably applied thereto via a selective laser sintering (SLS) process, wherein a powder layer is spread on the surface and fused with a laser. The adhesive layer can be a double layer comprising a white reactive adhesive layer that undergoes a crosslink reaction to become a thermoset and a substantially clear thermoplastic adhesive layer.

Color-selective waveguides, methods for fabricating color-selective waveguides, and augmented reality (AR)/mixed reality (MR) applications including color-selective waveguides are described. The color-selective waveguides can advantageously reduce or block stray light entering a waveguide (e.g., red, green, or blue waveguide), thereby reducing or eliminating back-reflection or back-scattering into the eyepiece.
