Abstract
A system for providing wire-free and contact free electric power and communication connection in a security installation between a door and a frame. The cores, windings, and control circuits of first and second transformers portions are disposed in the frame and the door, respectively. Power applied to the first transformer portion induces a voltage and current in the second transformer portion when the door is in a closed position. Fiber optic cables housed within the transformer portions transmit and receive data between the door and the frame. Power transfer occurs at 100+ KHz and data transfer is in the range of 100 K baud. The transformers portions are compactly constructed and, in one aspect of the invention, may reside in an opening normally occupied by a dead bolt. In another aspect of the invention, the transformer portions are fixed and resonating circuitry is off-tuned to optimize output levels.
