Abstract: An electronic device includes an electronic component with a mating surface. A thermal interface sheet is attached to the mating surface. A substrate carries the electronic device and includes a face. The electronic component is secured to the substrate with the thermal interface sheet positioned between the mating surface and the face. The mating surface is relatively less flat than the face and the mating surface is relatively smoother than the face.

Abstract: A carbon foam battery useful for electrical applications is disclosed which includes a relatively low conductivity low density high porosity carbon foam.
Abstract: A system and method for monitoring the operating parameters of an electric arc furnace having a primary electrical circuit comprising a primary current transformer. The method includes monitoring the furnace's primary current transformer; collecting data therefrom; transmitting the collected data to a server having an operatively connected monitor; and displaying the collected data on the monitor in substantially real-time. The server also collects information about the performance of the furnace from a programmable logic computer and information entered manually by an operator at a furnace monitoring viewer system, which may also be displayed in substantially real-time on the monitor.
