Cables incorporating discontinuous shielding elements are described. The family includes at least two engine configurations selected from a single cylinder, V-type, inline, opposed, W-type, and radial configurations. The first thermal energy extraction structure is configured to extract a first portion of thermal energy from the first electrical component through the first thermally conductive film layer and the first thermally conductive structure. A lever is pivotally secured to the tube and has a catch selectively engaging into the pipe for detachably securing the pipe to the tube. The other end of the first transistor, the other end of the second transistor, the other end of the third transistor, and the other end of the fourth transistor are coupled to generate an output end.
