Electric vehicle charging apparatus and methods are described which allow the sharing of charge current between multiple vehicles connected to a single source of charging energy. In one embodiment, a wind resistant exterior covering includes a first panel fastened to a substrate and a second panel fastened to the substrate. The shroud is made of a material meeting at least UL Standard 94HB, and at least its inner surface is non-reflective to hide the shroud structure when viewed through openings in the grille. The spring constant of the micromirror structure can be designed independently of the stiffness of the mirror-surface. An electrical stringed musical instrument in combination with the pickup unit cavity is additionally provided. The user interface includes a receiving mechanism configured to receive the anomaly-detection outcomes, a display that displays the anomaly-detection outcomes at a first resolution, and a command-receiving mechanism configured to receive commands from the user.
