A low mass electric linear motor having a magnet assembly with a plurality of magnets fixed to a base member. An ultra-wideband transmission is encoded by positioning bipolar pulse pairs. The system automatically generates complex content from protocol elements in the database, and can render overlapping sets of protocol elements differently at different locations in the document. The bus line or the lines isare monitored by the at least one receiving subscriber for an overshoot or undershoot of voltage levels.
