Abstract

Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a receiving member, a conductive bolt member adapted to be snap-locked into the receiving member, and a plastic encapsulant which tethers the bolt member to the receiving member. The encapsulant can contain an electrically conductive medium, such as a wire, which runs from the receiving member to the second end of the bolt. A sensory circuit disposed within the receiving member can be 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 present time and/or date in memory. An RFID transponder disposed within the encapsulant or the receiving member can then transmit the recorded date/time to an RFID interrogator if a dispute subsequently arises as to when the lock had been broken.

Claims

1. A lock device comprising:

a bolt member having a first end and a second end;

a receiving member configured to receive first end of the bolt member;

an encapsulant having a first end physically connected to the receiving member and a second end physically connected to the second end of the bolt member;

a sensory circuit disposed within the encapsulant and between the first and second ends of the encapsulant and configured to form a continuous electrical pathway that electrically connects the bolt member and the receiving member, wherein the sensory circuit is configured to detect an interruption of the continuous electrical pathway;

a conductive medium disposed within the encapsulant that connects the receiving member to the second end of the bolt member, wherein, within the encapsulant, the sensory circuit is coupled to the conductive medium, wherein the electrically conductive pathway is formed from the conductive medium and the sensory circuit when the first end of the bolt member is received by the receiving member; and

a communication circuit coupled to the sensory circuit and configured to transmit data indicative of the detected interruption.

2. The lock device of claim 1, further comprising a memory configured to store the data indicative of the detected interruption in response to detecting the interruption.

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

4. The lock device of claim 1, wherein the communication circuit is configured to transmit the data indicative of the interruption in response to a query.

5. The lock device of claim 4, wherein the sensory circuit is configured to store a unique identifier associated with the lock device, and the communication circuit is further configured to transmit the identifier in response to the query.

6. The lock device of claim 4, wherein the sensory circuit is configured to store information with respect to at least one of a nature of a shipment or one or more contents of the shipment, and the communication circuit is further configured to transmit at least a portion of the information in response to the query.

7. The lock device of claim 4, wherein the sensory circuit is configured to store a unique identifier associated with the lock device and 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 the communication circuit is further configured to transmit the identifier and the log in response to the query.

8. The lock device of claim 1, wherein the communication circuit comprise transponder including a radio frequency identification (RFID) chip and an antenna, and wherein the transponder is configured to transmit the data indicative of the detected interruption over a wireless connection.

9. The lock device of claim 1, wherein the communication circuit comprises a serial bus configured to transmit the data indicative of the detected interruption over a wired connection.

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

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

12. The lock device of claim 1, wherein the continuous electrical pathway is formed in response to the receiving member receiving the bolt member.

13. The lock device of claim 11, wherein the encapsulant is configured to tether the bolt member to the receiving member and comprises an electrically conductive medium connected to receiving member and the bolt member.

14. A method comprising:

detecting an interruption of a continuous electrical pathway electrically connected to a second end of a bolt member and a receiving member configured to receive a first end of the bolt member, the continuous electrical pathway electrically formed from a conductive medium and a sensory circuit when the first end of the bolt member is received by the receiving member, the sensory circuit disposed within an encapsulant connected to the receiving member and the second end of the bolt member and disposed between a first end of the encapsulant physically connected to the receiving member and a second end of the encapsulant physically connected to the second end of the bolt member, the conductive medium disposed within the encapsulant and connects the receiving member to the second end of the bolt member, and the sensory circuit is coupled to the conductive medium within the encapsulant; and

transmitting data indicative of the interruption.

15. The method of claim 14, storing, in a memory, the data indicative of the detected interruption in response to detecting the interruption.

16. The method of claim 14, further comprising transmitting the data indicative of the interruption in response to a query.

17. The method of claim 15, further comprising:

storing a unique identifier associated with the sensory circuit, and

transmitting the identifier in response to the query.

18. The method of claim 15, 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.

19. The method of claim 15, 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.
