Fuses, and optionally metal pads, are formed over a layer of low k dielectric material structure having first openings lined with conductive barrier material and filled to form metal interconnects in the upper surface of the low k dielectric material. The hopper has a body having an open top and plurality of walls, at least one guide extending between at least two of the plurality of walls, and an indicator to provide indication that the hopper contains a first and a second predetermined volume of aggregate. Secure message interchange between the examining attorneys and between defending attorneys is provided along independent communication links and using encryption. In an additional embodiment, the dielectric layer can have a dielectric constant that changes in a predetermined fashion between at least a portion of the induction coil and the conductive member to allow for a uniform current distribution in the resonator device. The guard structure is disposed in a plane above the conductive surfaces such that the conductive surfaces are not completely covered by the guard structure.
