Patent ID: 7958758

Claim:
A locking device comprising: a key comprising a key power coil and a key data coil, wherein said key power coil and said key data coil each comprises an inductor; and an electronically-actuatable lock comprising a lock power coil and a lock data coil, said key power coil and said lock power coil being coaxial and at least partially overlapping one another when said key engages said lock, said key data coil lying in a first plane, said lock data coil lying in a second plane, said first plane and said second plane being substantially parallel to one another, wherein: the lock power coil comprises a plurality of first wire windings surrounding a longitudinal axis, the lock data coil comprises a plurality of second wire windings defining a substantially toroidal-shaped coil surrounding a central axis, and wherein the lock data coil lies in a plane substantially orthogonal both to the central axis of the lock data coil and to the longitudinal axis of the lock power coil, thereby attenuating magnetic interference between the lock power coil and the lock data coil and enabling the transmission of data and power simultaneously between the key and the lock.
