Abstract

A security device is provided including a security lock configured to retain an object when locked, a receiver configured to receive a security code transmission, and processing circuitry configured to transition the security lock between a locked state and unlock permissive state based on receipt of a security code. The security lock may initially be set to the unlock permissive state. At the first instance in which a security code is received, the processing circuitry may transition the security lock to a key permissive mode in which the security lock transitions to a locked state and in response to a subsequent receipt of the security code the security lock transitions to the unlock permissive state.

Claims

1. A security device comprising:

a security lock configured to retain an object when locked;

a receiver configured to receive a security code transmission; and

processing circuitry configured to transition the security lock between a locked state and an unlock permissive state based on receipt of the security code;

wherein the security lock is initially set to the unlock permissive state;

wherein at a first instance in which the security code is received, the processing circuitry transitions the security lock to a key permissive mode and the security lock transitions to a locked state; and

wherein in response to a subsequent receipt of the security code the security lock transitions to the unlock permissive state.

2. The security device of claim 1, wherein the security lock is configured to, in response to the subsequent security code receipt, remain in the unlock permissive state for a predetermined period of time, and wherein the security lock is configured to transition to the locked state in response to an expiration of the predetermined period of time.

3. The security device of claim 1, wherein the security code is transmitted on a frequency in an audible frequency band.

4. The security device of claim 1, wherein the security code is transmitted on a frequency in a frequency band including 4 kHz.

5. The security device of claim 1, wherein the security lock comprises a magnetic security lock.

6. The security device of claim 1, wherein the security lock further comprises a lanyard configured to encompass at least a portion of the object.

7. The security device of claim 1 further comprising:

an alarm configured to occur in response to removal of the security device without unlocking the security lock.

8. The security device of claim 1, wherein the processing circuitry is configured to:

store the security code to a memory at the first instance in which the security code is received; and

compare a received security code to the security code stored in the memory;

wherein the transition from the locked state to the unlock permissive state is in response to the received security code matching the security code stored in memory.

9. The security device of claim 1, wherein the security lock is a tube lock.

10. A security system comprising:

a security device comprising;

a security lock configured to retain an object when locked;

a receiver configured to receive a security code transmission; and

processing circuitry configured to transition the security lock between a locked state and unlock permissive state based on receipt of a security code;

wherein the security lock may initially be set to the unlock permissive state;

wherein at a first instance in which a security code is received, the processing circuitry may transition the security lock to a key permissive mode and the security lock transitions to a locked state; and

wherein in response to a subsequent security code receipt the security lock transitions to the unlock permissive state; and

a release device configured to cause a transmission of the security code.

11. The security system of claim 10, wherein the security device is configured to, in response to the subsequent security code receipt, remain in the unlock permissive state for a predetermined period of time, and wherein the security device is configured to transition to the locked state in response to an expiration of the predetermined period of time.

12. The security system of claim 11, wherein the predetermined period of time is about 30 seconds to 60 seconds.

13. The security system of claim 10, wherein the security code is transmitted on a frequency in an audible frequency band.

14. The security system of claim 10, wherein the security code is transmitted on a frequency in a frequency band including 4 kHz.

15. The security system of claim 10, wherein the security lock comprises a magnetic security lock.

16. The security system of claim 10, wherein the security lock further comprises a lanyard configured to encompass at least a portion of the object.

17. The security system of claim 10, wherein the security device further comprises an alarm configured to occur in response to removal of the security device without unlocking the security lock.

18. The security system of claim 10, wherein the processing circuitry is configured to:

store the security code to a memory at the first instance in which the security code is received; and

compare a received security code to the security code stored in memory;

wherein the transition from the locked state to the unlock permissive state is in response to the received security code matching the security code stored in memory.

19. The security system of claim 10, wherein the release device is further configured to unlock the security lock when the security lock is in the unlock permissive state.

20. The security system of claim 10, wherein the security lock is a tube lock.
