Abstract

A programmable security system and method for protecting an item of merchandise includes a programming station, a programmable key and a security system. The programming station generates a security code and communicates the security code to a memory of the programmable key. The programmable key initially communicates the security code to a memory of the security device and subsequently operates the security device upon a matching of the security code in the memory of the security device with the security code in the memory of the programmable key. The programmable key may also transfer power via electrical contacts or inductive transfer from an internal battery to the security device to operate a lock mechanism. The security code may be communicated by wireless infrared (IR) systems, electrical contacts or inductive transfer. A timer inactivates the programmable key and/or the security device after a predetermine period of time. A counter inactivates the programmable key after a predetermined maximum number of activations.

Claims

1. A programmable security system for protecting merchandise comprising:

a programmable key having a memory for storing a security code and a power source; and

a security device having a memory for storing the security code;

wherein the programmable key is configured to transfer power from the power source to the security device,

wherein the security device is configured to be operated using power transferred from the programmable key to the security device when the security code stored in the memory of the security device matches the security code stored in the memory of the programmable key.

2. The programmable security system of claim 1,

wherein the programmable key comprises means for inducing a magnetic field and the security device comprises means for inducing an electrical current from the magnetic field;

and

wherein the programmable key is adapted to transfer power from the programmable key to the security device via the magnetic field induced in the programmable key and the electrical current induced in the security device.

3. The programmable security system of claim 1, further comprising a programming station configured to generate the security code and having a memory for storing the security code.

4. The programmable security system of claim 3, wherein the programming station is configured to initially communicate the security code to the programmable key to be stored in the memory of the programmable key.

5. The programmable security system of claim 1,

wherein the programmable key comprises a ferrite core and a conductive wire forming a plurality of windings about the ferrite core and electrically connected to the power source of the programmable key such that passing an electrical current through the conductive wire of the programmable key induces a magnetic field in the programmable key;

wherein the security device comprises a ferrite core and a conductive wire forming a plurality of windings about the ferrite core such that the magnetic field in the programmable key induces an electrical current in the conductive wire of the security device; and

wherein the programmable key is adapted to transfer power from the programmable key to the security device via the magnetic field induced in the programmable key and the electrical current induced in the security device.

6. The programmable security system of claim 1, wherein the security device is configured to communicate with the programmable key to receive the security code from the programmable key.

7. The programmable security system of claim 1, wherein the programmable key is configured to transfer power inductively to the security device.

8. The programmable security system of claim 1, wherein the programmable key is configured to transfer power to the security device via one or more electrical contacts.

9. The programmable security system of claim 1, wherein the security device does not have an internal power source.

10. The programmable security system of claim 1, wherein the power source is a rechargeable battery.

11. The programmable security system of claim 1, further comprising a charging station configured to charge the power source of the programmable key.

12. The programmable security system of claim 11, wherein the charging station is configured to charge the power source of the programmable key inductively.

13. The programmable security system of claim 1, wherein the programmable key comprises a housing enclosing the memory and the power source, wherein the housing comprises a transfer end configured to transfer power to the security device.

14. The programmable security system of claim 13, wherein the housing comprises an actuator configured to be manually actuated for initiating communication with the security device.

19. The method of claim 13, further comprising communicating the security code from the memory of the programmable key to the memory of a security device.

15. A method for protecting merchandise, comprising:

storing a security code in a memory of a programmable key;

storing the security code in a memory of a security device;

determining whether the security code stored in the memory of the security device matches the security code stored in the memory of the programmable key;

transferring power from a power source of the programmable key to the security device; and

operating the security device using power transferred from the programmable key to the security device when the security code stored in the memory of the security device matches the security code stored in the memory of the programmable key.

16. The method of claim 15, further comprising:

inducing a magnetic field in the programmable key; and

inducing an electrical current in the security device from the magnetic field,

wherein the transferring comprises transferring power from the programmable key to the security device via the magnetic field induced in the programmable key and the electrical current induced in the security device.

17. The method of claim 15, further comprising generating the security code in a programming station and storing the security code in a memory of the programming station.

18. The method of claim 17, further comprising communicating the security code from the memory of the programming station to the memory of a programmable key.

20. The method of claim 15, wherein the transferring comprises transferring power inductively from the programmable key to the security device.
