A method of testing a coating on a reflector having a first focal point includes placing a mirror at the first focal point of the reflector and angled to orient with an area on the coating. The adhesive composition includes a polar plasticizing oil or a combination of polar plasticizing oils in a content above 10%, and 10-50% of a polar polyethylene copolymer. The interpretation process uses the postprocessed data and determines loop characterization, interferer detection, a data reduction estimation and a data rate estimation. The patterns of release and adhesive enable the application of the pocket portion to a blank suitable for use in forming a presentation folder or other structure or item for which a pocket may be useful or beneficial. The composition may be sprayed onto the rail surface. The method includes coupling a current sensing circuit to an output of the LLC converter, sensing load current of the LLC converter, and increasing a setpoint voltage for a power factor correction circuit output based on the sensed load current.
