A polyurethane foam or elastomer comprises an organic polyisocyanate component, an active hydrogen-containing component reactive with the polyisocyanate component, wherein the viscosity of this component is less than about 500 cP at room temperature, a catalyst component, a surfactant, and a flame retarding composition. The method further includes applying an overdrive voltage to a gate of the selector to turn on the selector. The output signal is then converted with a noise reduction filter to obtain a filtered output signal. In some embodiments of the articles and methods, the adhesive and backing delaminate upon removal. The transaction is automatically completed following a temporary communication failure with the central site or following a temporary local controller failure. The coupler package has an inner and outer cylinder for providing additional buffering against vibration, temperature expansion, corrosion, and water penetration.
