Abstract

The device fixed to the rotating body comprises one or two flexible bands with either linear conductors perpendicular to the flexible direction of the band and interconnected so that a single phased current circulates in them due to induction by the magnets on the crown when the moving body rotates, or a transformer secondary having turns parallel to primary turns wound on the crown of the independent structure. A second annular zone has light transmitters which transmit radially towards the photosensitive layer on the independent body. A third annular zone amplifying, filtering and processing signals from remote sensing elements, prepares signals for modulating the light transmitters etc.
