In various embodiments, an electronic module features a first cavity in a first side of a substrate, a fill hole extending from the first cavity, and a second cavity in a second side of the substrate. Cooling is achieved by coherent scattering, where the frequency of the emitted radiation exceeds the frequency of the illumination radiation. Wave energy is captured as the float is displaced vertically and horizontally in response to wave action extending the hydraulic cylinder that in turn forces fluid under high pressure to the float where appropriate valves, hydraulic accumulators, and variable displacement hydraulic motors are arranged to drive electric generators. The backstop intercepts the baseball thrown through the zone assembly. The first dome has an outer surface that includes a truncated sphere characterized by a center for the spherical portion of the surface, and the die is situated at a position below the center.
