    Abstract: Power switch units for microelectronic devices are disclosed. In one aspect, a microelectronic device may include a functional circuit, and a power switch unit to switch power to the functional circuit on and off. The power switch unit may include a large number of transistors coupled together. The transistors may include predominantly positive-channel, insulated gate field effect transistors, which have a gate dielectric that includes a high dielectric constant material. Power switch units having such transistors may tend to have low power consumption. In an aspect, an overdrive voltage may be applied to the gates of such transistors to further reduce power consumption. Methods of overdriving such transistors and systems including such power switch units are also disclosed.

    Abstract: A prepolymer system has a monomeric isocyanate content of no greater than about 10% by weight based on 100 parts by weight of the prepolymer system. The prepolymer system comprises a diluent component and a prepolymer component different than and separate from the diluent component. The diluent component has an excess of isocyanate (NCO) functional groups, and comprises the reaction product of a monohydric isocyanate-reactive component and an excess of a first isocyanate component. The first isocyanate component comprises monomeric isocyanates reactive with the monohydric isocyanate-reactive component. The prepolymer component also has an excess of NCO functional groups, and comprises the reaction product of a polyol component and an excess of a second isocyanate component. The prepolymer system can be used to prepare foams via reaction with water. The foams have low density and have excellent adhesion and sound dampening properties for use in cavities of automobile bodies.
