Abstract
An electronics support apparatus for rotating electronics is provided that eliminates the need for electrical contact brushes and/or reduces the number of inductive power coupling coil pairs required to provide power to the rotating electronics. With the apparatus, a single inductive power coupling coil pair is utilized in which the coils are oriented at approximately 90 degrees, i.e. at a right angle, to each other, e.g., the “outer” coil (secondary transformer coil) is oriented approximately 90 degrees to the “inner” coil (primary transformer coil). A transformer core, or “elbow core,” having an approximately 90 degree bend is provided for coupling the magnetic energy of the primary transformer coil with the secondary transformer coil, thus imparting or coupling energy simultaneously through 2 axes of motion.
