Abstract: A charging station for an electric vehicle includes a passive alignment mechanism that includes a longitudinal translation stage that allows motion in a longitudinal direction, a charging plug connected to the passive alignment mechanism, and a releasable connector. The releasable connector resists motion of the longitudinal translation stage in a connected position when a magnitude of an external force applied in the longitudinal direction is below a threshold. The releasable connector moves from the connected position to a released position to allow motion of the longitudinal translation stage when the magnitude of the external force applied in the longitudinal direction is above the threshold.

Abstract: A solar tracking system for mounting on a roof having one or more rooftop planar surfaces includes an array of solar tracking assemblies for at least one of the one or more rooftop planar surfaces, each array of solar tracking assemblies mountable at substantially the same orientation on the rooftop planar surface, each solar tracking assembly including a mounting structure, a steering mechanism, and one or more energy converting units that convert solar energy into electrical energy, the steering mechanism supported at least in part by the mounting structure and the one or more energy converting units steered by the steering mechanism; a drive mechanism that drives multiple steering mechanisms of the array of solar tracking assemblies; and a control processor that controls the drive mechanism so that the one or more energy converting units follow the sun.
