ABSTRACT:
A system that allows inductive connectors to be electrically coupled without having to mechanical align the same. The connectors have a primary coil coupled to a secondary coil. The primary coil transmits either power or digital signals to the secondary coil. The power induced onto the secondary coil is a function of the distance between coils. The farther apart the coils are, the less power is transmitted to the secondary coil. To insure that the proper level of power is received by the secondary coil, a feedback circuit is incorporated to vary the output of power on the primary coil as a function of the voltage induced onto the secondary connectors. If connectors are spaced apart beyond a predetermined distance, the feedback system increases the power on the primary coil.
