An apparatus is provided that includes a wave generator, plurality of transducers and processing device. The circuit board includes a substrate, a waveguide line and a laminated waveguide. A first light filter system is positioned at a light-input end of the device, and a second light filter system is positioned at a light-output end of the device, whereby the plurality of filters systems provide to a viewer a sensation of full color, including from red to blue with white and black. This two component system is designed for installation at wall-to-deck junctures by incorporating a form of a wall \u201csaddle\u201d flashing having one or more wall plates with attached \u201cL\u201d flashing extension with cleats and cover plate extensions. Further, the method includes increasing a time period of a sleep timer of the wireless end node when the missed acknowledgment counter value equals a missed acknowledgment threshold.
