Abstract

Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a bolt member having a conductive medium running the axial length of the bolt, and a receiving member for locking the bolt into place. A battery-driven sensory circuit including a memory means, a processor, and a timing circuit can be disposed within the receiving member such that a continuous circuit is formed from one circuit pin over the conductive medium through the length of the bolt and back to a second pin. The sensory circuit is configured to sense whether the circuit has been interrupted (e.g., if the bolt has been cut). In the event of an interruption, the circuit can record the time and/or date in memory. This information can then be transmitted to an RFID reader/interrogator if a dispute arises as to when the lock had been broken.

Claims

1. A lock device comprising:

a bolt member comprising a first end and a head at a second end;

a circuit comprising at least one electrical contact adapted to electrically interface with a first end of a bolt member to form a continuous circuit by an electrically conductive pathway running along the axial length of the bolt member and terminating at the head, wherein the circuit is adapted to detect an interruption in the continuous circuit; and

a transponder coupled to the circuit and configured to store data indicative of the interruption in response to detecting the interruption of the continuous circuit.

2. The lock device of claim 1, wherein the data comprises at least a date and a time of the interruption.

3. The lock device of claim 1, wherein the transponder coupled is configured to transmit the data in response to a query.

4. The lock device of claim 3, wherein the transponder is further configured to:

store a unique identifier associated with the lock device, and

transmit the identifier in response to the query.

5. The lock device of claim 3, wherein the transponder is further configured to:

store information with respect to at least one of the following;

a nature of a shipment, or one or more contents of the shipment; and

transmit at least a portion of the information in response to the query.

6. The lock device of claim 3, wherein the transponder is further configured to:

store a unique identifier associated with the lock device;

periodically receive and store information related to multiple transit locations and/or multiple handling parties of a container comprising the lock device to create a log; and

transmit the identifier and the log in response to the query.

7. The lock device of claim 3, wherein the transponder includes a radio frequency identification (RFID) chip, and wherein the transponder is configured to transmit the identifier over a wireless connection.

8. The lock device of claim 3, wherein the transponder is connected to a serial bus, and wherein the transponder is configured to transmit the identifier over a wired connection.

9. The lock device of claim 1, wherein circuit is adapted to detect that the continuous circuit is shorted.

10. The lock device of claim 1, wherein circuit is adapted to detect that the continuous circuit is open.

11. The lock device of claim 1, further comprising a receiving member adapted to receive a first end of the bolt member that, in response to receiving the first end of the bolt member, forms the continuous circuit.

12. The lock device of claim 1, wherein a transponder is configured to store a date and time that the continuous circuit is shorted or opened.

13. The lock device of claim 12, wherein the transponder is further configured to:

store a unique identifier associated with the lock device;

periodically receive and store information related to multiple transit locations and multiple handling parties of a container comprising the lock device to create a log; and

transmit the unique identifier, date and a time of the interruption, and the log in response to a query.

14. The lock device of claim 1, wherein the electrically conductive pathway is positioned at a radial edge of the bolt member.

15. A method comprising:

detecting an interruption of a continuous circuit in a lock device, the lock device comprising the continuous circuit between a bolt member and a circuit, the bolt member comprising a first end and a head at a second end, the circuit comprising at least one electrical contact adapted to electrically interface with a bolt member to form the continuous circuit by an electrically conductive pathway running along the axial length of the bolt member and terminating at the head; and

storing data indicative of the interruption in response to detecting the interruption.

16. The method of claim 15, wherein the data comprises at least a date and a time of the interruption.

17. The method of claim 15, further comprising transmitting the data in response to a query.

18. The method of claim 17, further comprising:

storing a unique identifier associated with the lock device, and

transmitting the identifier in response to the query.

19. The method of claim 17, further comprising:

storing information with respect to at least one of the following;

a nature of a shipment, or one or more contents of the shipment, and

transmitting at least a portion of the information in response to the query.

20. The method of claim 17, further comprising:

storing a unique identifier associated with the lock device;

periodically receiving and storing information related to multiple transit locations and/or multiple handling parties of a container comprising the lock device to create a log; and

transmitting the identifier and the log in response to the query.
