Contactless battery charging apparel

Image Number 9 for United States Patent #7994752.

A sequential power transmission between a portable user-carried battery and first and second independent accessories. At least one primary inductive coupling coil is mounted on an article of apparel worn by the user, so as to place a primary coil adjacent a first intermediary inductive coupling coil on the first independent accessory. The energizing of the first intermediary coil energizes a second intermediary coil on the first independent accessory. The second intermediary coil, when energized, energizes a secondary coil on the second independent accessory for powering the use, including the charging of the batteries of that accessory.
