Abstract

Systems, apparatuses, and methods are provided herein for securing merchandise. In one embodiment an apparatus for securing merchandise comprises a locking mechanism limiting access to one or more items, one or more optical sensors configured to detect a plurality of wavelengths and an intensity associated with each wavelength from at least one light beam emitted by an optical key, and a control device comprising a control circuit and a memory device. The control device being configured to store a lock code comprising a plurality of wavelength values and a plurality of intensity values each associated with a wavelength value on the memory device and determine whether to release the locking mechanism based on whether intensities of each of the plurality of wavelengths detected by the one or more optical sensors match the lock code.

First claim

What is claimed is:

1. A system for securing items comprising:
a communication device configured to communicate with:
a plurality of optical keys, each optical key comprises one or more light sources configured to emit at least one light beam; and
a plurality of optical locks, each optical lock comprising one or more optical sensors configured to detect a plurality of wavelengths and an intensity associated with each wavelength; and
a control circuit coupled to the communication device and configured to:
receive an unlock request associated with an optical key;
determine a lock code for an optical lock, wherein the lock code comprises a plurality of wavelength values and a plurality of intensity values each associated with a wavelength value; and
send the lock code to at least one of the optical key and the optical lock to allow the optical key to access items secured by the optical lock.

2. The system of claim 1 , wherein at least one of the one or more optical sensors comprise a spectrometer.

3. The system of claim 1 , wherein the optical lock comprise a plurality of sensors arranged in a pattern matching a pattern of light sources in the optical key.

4. The system of claim 1 , wherein the unlock request comprises one or more of an identifier of a user making the unlock request, an authentication code, and an optical lock identifier, a location of the optical key, and a merchandise identifier.

5. The system of claim 1 , wherein the lock code further comprises a modulation scheme and the optical lock is further configured to determine whether to release a locking mechanism based on whether a modulation of the at least one light beam from the optical key matches the modulation scheme in the lock code.

6. The system of claim 1 , wherein the optical lock uses a rotating lock code and the control circuit determines the lock code based on a current date and/or time.

7. The system of claim 1 , wherein the lock code is determined based on an identifier associated with the optical lock.

8. The system of claim 1 , wherein the lock code comprises a one-time use code.

9. The system of claim 1 , wherein the control circuit is further configured to log accesses of the plurality of optical locks.

10. The system of claim 1 , wherein the control circuit is further configured to log a number of items removed from or added to a locked space associated with the optical lock.

11. A method for securing items comprising:
receiving, at a control circuit and via a communication device, an unlock request associated with an optical key among a plurality of optical keys configured to emit at least one light beam;
selecting, with the control circuit, an optical lock based on the unlock request, wherein the optical lock is selected from a plurality of optical locks each comprising one or more optical sensors configured to detect a plurality of wavelengths and an intensity associated with each wavelength;
determining, with the control circuit, a lock code for the optical lock, wherein the lock code comprises a plurality of wavelength values and a plurality of intensity values each associated with a wavelength value; and
send, via the communication device, the lock code to at least one of the optical key and the optical lock to allow the optical key to access items secured by the optical lock.

12. The method of claim 11 , wherein at least one of the one or more optical sensors comprise a spectrometer.

13. The method of claim 11 , wherein the optical lock comprise a plurality of sensors arranged in a pattern matching a pattern of light sources in the optical key.

14. The method of claim 11 , wherein the lock code further comprises a modulation scheme and the optical lock is further configured to determine whether to release a locking mechanism based on whether a modulation of the at least one light beam from the optical key matches the modulation scheme in the lock code.

15. The method of claim 11 , wherein the unlock request comprises one or more of an identifier of a user making the unlock request, an authentication code, and an optical lock identifier, a location of the optical key, and a merchandise identifier.

16. The method of claim 11 , wherein the optical lock uses a rotating lock code and the control circuit determines the lock code based on a current date and/or time.

17. The method of claim 11 , wherein the lock code is determined based on an identifier associated with the optical key.

18. The method of claim 11 , wherein the lock code comprises a one-time use code.

19. The method of claim 11 , further comprising:
logging accesses of the plurality of optical locks.

20. The method of claim 11 , further comprising:
logging a number of items removed from or added to a locked space associated with the optical lock.
