Abstract: A conductive material includes a graphene-nanonsheet material, with charge-storage material in voids in and/or coating the graphene material. The charge-storage material may include any of a variety of types of carbon, including carbon black, acetylene black, furnace black, carbon fibers, carbon nanotubes, graphene in the form of wrinkled sheets of graphene, carbon nano-onions, or hydrothermal-synthesized nanospheres of carbon material. Alternatively, the charge-storage material may be non-carbon pseudocapacitive materials. Also, the charge-storage material may involve Faradaic processes similar to those observed with battery electrodes. The conductive material may be formed or placed on a conductive or a dielectric substrate. One or more gaps may be formed in the conductive material, with the conductive material forming two or more electrodes. The electrodes may then be covered with an electrolyte material, to produce an electric double layer capacitor.

Abstract: An electrical connector having a plurality of contacts divided into three groups based on height and location where the first group is tall in a peripheral array, the second group is short in the peripheral array and the third group is short in a smaller inner array. A first electrically conductive plate is mounted to the first group of contacts and fastened by screws which are received in central longitudinal threaded holes in the first group of contacts. In a like manner, a second electrically conductive plate is connected to the third group of contacts using screws which are received in central longitudinal holes of the short contacts. Each of the plates has a central opening which is fitted with a screw which allows electrical connections to be made with other circuitry or components.
