This invention generally relates to automated shade systems. The transformer includes a bobbin; a magnetic core assembly partially sleeved by the bobbin; a first primary winding coiled around the bobbin; a secondary winding coiled on the first primary winding; and a first shielded element disposed between the first primary winding and the secondary winding for disconnecting the EMI transmission from the first primary winding to the secondary winding. The merging of faces reduces the number of vertices needed. To open the container and cap assembly, the tear strip is pulled across the label to separate the two panels of the label. The light enters a decentered prism through a surface and is reflected successively by surfaces. An information receiving apparatus is mounted on each automobile running on the ground and it receives the multiplexed information.
