Abstract: Provided are systems for and methods of providing an integrated drain system and shower base. The drain system comprises a bonding flange drain that has a flange defining a drain opening, a substrate encompassing the outer portion of the flange and supporting the flange, and a waterproof membrane having a fibrous surface. A bonding material couples the membrane to the substrate. A drain tube having an inner rim and operable to removably seal with the lower end of the bonding flange drain using a coupling interface that includes a silicon seal.

Abstract: An air cleaner includes a rear filter receiving air from the outer environment, an ionizer grid connected to a high voltage power supply and having wires extending between opposite sides of a frame such to emit positively charged ions and apply an electrostatic charge on the air received from the rear filter; a collector grid connected to ground and having wires extending between opposite sides of a frame, the combination of the ionizer and collector grids causing the air to move toward the collector grid; a front filter collecting contaminants suspended in the air received from the collector grid; and an apparatus frame housing the rear filter, the ionizer and collector grids, and the front filter, wherein the frames of the ionizer and collector grids are suspended within the apparatus frame with isolating members made of a non-arc tracking material, such to minimize coronal discharge and reduce audible noise.

Abstract: A method for the selective encapsulation of electronic components on a printed circuit board comprising, in one embodiment, the steps of delivering the printed circuit board to an encapsulating nest at room temperature; damming the target areas with a dam resin having a latent curing agent and deposited in the shape of walls of predetermined heights, according to the desired fill heights; dispensing a fill resin to fill the dammed areas; and curing the dam and fill resins for a suitable amount of time. In a different embodiment, the invention comprises the additional steps of laying resin beads, each in a position corresponding to the footprint of each target component; and of positioning the target components over the beads and soldering the components.
