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.

First claim

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.
