System for Providing Power and Data Transmission Between a Door and a Frame
First Claim
1. A system for providing electric power and communication from a first object to a second object wherein at least one of said first and second objects is moveable with respect to the other, said system comprising:
- a transformer assembly including a first transformer portion having a first coil winding and a second transformer portion having a second coil winding, wherein said first transformer portion is configured for being disposed in said first object and wherein said second transformer portion is configured for being disposed in said second object;
a first element configured for receiving said first transformer portion on said first object, said first element including a first contact surface;
a second element configured for being slidably disposed in said second object and for receiving said second transformer portion, said second receiver element including a second contact surface;
a biasing member configured for biasing said second contact surface toward said first contact surface so that said second contact surface engages said first contact surface to define a predetermined gap between said first transformer portion and said second transformer portion;
wherein, when said first contact surface is engaged with said second contact surface, an application of a first alternating electric current through said first coil winding induces a second alternating current in said second coil winding.

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.

8. A system for providing electric power and communication from a first object to a second object wherein at least one of said first and second objects is moveable with respect to the other, comprising:
-
a) a first transformer portion disposed on said first object adjacent said second object and having a first core half, a first coil winding and a first fiber optic cable; b) a second transformer portion disposed on said second object adjacent said first object and having a second core half, a second coil winding and a second fiber optic cable; c) first circuitry connected to said first transformer portion; and d) second circuitry connected to said second transformer portion; wherein application of a first alternating electric current through said first coil winding induces a second alternating current in said second coil winding, and wherein light emission from one of said first or second fiber optic cables and receipt of said light emission by the other of said first or second fiber optic cables defines a communications signal between said first object and said second object. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for providing electric power and communication from a first object to a second object wherein at least one of said first and second objects is moveable with respect to the other, comprising:
-
a) a first transformer fixedly disposed on said first object adjacent said second object and having a first core and a first coil winding; b) a second transformer fixedly disposed on said second object adjacent said first object and having a second core and a second coil winding; c) first circuitry connected to said first transformer; and d) second circuitry connected to said second transformer; wherein application of a first alternating electric current through said first coil winding induces a second alternating current in said second coil winding and wherein a first resonance frequency of said first transformer is off-tuned from a second resonance frequency of said second transformer. - View Dependent Claims (17, 18, 19, 20)
