Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.

Abstract: A shower rod mounting assembly is provided with a flexible substrate having a first side and a spaced apart second side. A reversible dry adhesive layer at least partially covers the first side of the substrate to attach the flexible substrate to a surface and leave the underlying surface unmarked after removal. The reversible adhesive retains an adhesion property for a plurality of adhesion cycles. A receptacle is mounted to the second side and is adapted to receive an end of a shower rod. A boss extends from the substrate with a track formed therein with an opening to receive an end of a shower rod. A biasing member extends from the substrate adjacent to the opening to retain the end of the shower rod after installation.

Abstract: A swatch assembly includes a substrate with a decorative sample thereon, and an adhesive layer at least partially covering the substrate. The adhesive layer is a reversible adhesive configured to releasably and temporarily attach the design swatch to an underlying surface, leave the underlying surface unmarked after removal, and retain an adhesion property for a plurality of adhesion cycles. A design system includes a first design swatch with a first substrate and a first adhesive layer being a reversible adhesive, and a second design swatch with a second substrate and a second adhesive layer being a reversible adhesive. A display apparatus for a design swatch includes a substrate layer, an adhesive layer being a reversible adhesive, and an attachment feature supported by the substrate layer and configured to receive a design swatch for display against an underlying surface.

Abstract: A stencil includes a substrate defining at least one aperture extending therethrough. The at least one aperture provides a template for painting a design on an underlying surface. The stencil is also provided with an adhesive layer at least partially covering one side of the substrate. The adhesive layer is a reversible adhesive configured to temporarily attach the stencil to an underlying surface and leave the underlying surface unmarked after removal. The reversible adhesive retains an adhesion property for a plurality of adhesion cycles.
