Abstract: A power transfer system for imparting power to at least one functional element, such as a movable glass-containing functional element, such as a sliding glass door. The power transfer system preferably includes a magnetic induction power transfer mechanism with a power transfer circuit having first and second separated coils, and a resonant circuit power driver having a resonant frequency. The power transfer mechanism is designed to apply power to the functional element and/or to other devices or systems connected to it. The power transfer system may include an electronic feedback mechanism with an electronic feedback circuit for sensing a predetermined condition concerning the functional element.
