Abstract

A container seal device is provided that comprises a seal device for a shipping container, comprising a first unit that is affixed to a shipping container. A control system is contained in the first unit containing a control system. A second unit is provided that is configured to engage with an element of a door of a shipping container to which the first unit is affixed and to electrically connect with the control system in the first unit. The control system in the first unit is configured to detect a breach of the second unit indicative of access being made to the shipping container.

Claims

1. A seal device for a shipping container, comprising:

a first unit that is affixed to a shipping container, the first unit containing a control system; and

a second unit that is configured to engage with an element of a door of a shipping container to which the first unit is affixed and to electrically connect with the control system in the first unit;

wherein the control system in the first unit is configured to detect a breach of the second unit indicative of access being made to the shipping container.

2. The device of claim 1, wherein the first unit comprises an electrical connector and the second unit comprises an electrical connector that mates with the electrical connector of the first unit.

3. The device of claim 2, wherein the control system of the first unit comprises a main controller that detects when the second unit is electrically connected to the first unit and establishes an armed state during which the main controller monitors conditions of the second unit to detect a breach of the second unit that is indicative of access to the shipping container to which the first unit is attached.

4. The device of claim 3, wherein the second unit comprises a cable comprising a first end and a second end, wherein the first end of the cable is connected to the electrical connector of the second unit, and the first unit comprises a housing that contains the control system and comprises passageway that is configured to permit the second end of the cable to pass through but which prevents the cable from being withdrawn from the passageway once it has been inserted without cutting the cable, and wherein the main controller establishes the armed state once the cable has been inserted into the passageway.

5. The device of claim 4, wherein the cable comprises one or more conductors and/or optical fibers, and the main controller monitors the one or more conductors and/or optical fibers to detect when the cable is cut.

6. The device of claim 3, wherein the control system of the first unit comprises global positioning system (GPS) device that receives global positioning signals in order to determine a position of the shipping container to which the first unit is affixed, and one or more communication modules capable of wireless communication for transmitting the position of the shipping container.

7. The device of claim 6, and further comprising at least one sensor that is coupled to the main controller in the first unit and which detects a condition indicative of a intrusion into the shipping container.

8. The device of claim 6, wherein the at least one sensor comprises an acoustic sensor that monitors vibrations in a wall of the shipping container.

9. A container monitoring system comprising an administration facility and the seal device of claim 6, wherein the administration facility communicates with the seal device in order to track conditions of the seal device including the geographical position of the seal device and occurrence of a breach of the second unit during the armed state.

10. The system of claim 9, wherein the main controller in the first unit generates a disarming confirmation message for transmission via one of the communication modules to the administration facility upon determining that the seal device has been breached at a geographical position where a breach of the seal device is authorized.

11. The system of claim 9, wherein the administration facility transmits a disarm message to the first unit, and wherein the main controller of the first unit is responsive to the disarm message to activate a visual indicator on the first unit.

12. The system of claim 11, wherein the memory of the second unit stores data indicating which of a plurality of function types the seal device is to perform when the second unit is electrically connected to the first unit, and wherein the main controller in the first unit generates one or more disarm identifiers for the seal device depending on the function type the seal device is configured to perform.

13. The device of claim 1, wherein the second unit is configured for a single use and is disposable after the single use.

14. The device of claim 1, and further comprising a digital camera coupled to the main controller of the first unit, wherein the digital camera is positioned in the first unit so as to capture images of a person attempting access into the container through the container door or interacting with the first unit or second unit.

15. An apparatus, comprising:

a housing unit that is configured to attach to a shipping container, wherein the housing unit contains a control system comprising one or more wireless communication modules;

a seal unit comprising an engaging member that is configured to engage with a portion of a door mechanism of a shipping container to which the housing unit housing is attached, and an electrical connector attached to the engaging element and configured to electrically connect to the control system in the housing unit;

wherein the control system in the control unit housing detects a breach of the seal unit that is indicative of access being made to the shipping container and transmits a message indicating the breach via the one or more wireless communication modules.

16. The apparatus of claim 15, wherein the control system of the housing unit comprises a main controller that establishes an armed state when the seal unit electrically connects to the control unit and thereafter monitors conditions of the seal unit to detect a breach of the seal unit indicative of access to the shipping container.

17. The apparatus of claim 15, wherein the seal unit comprises a power source that supplies electrical power to the control system when connected thereto.

18. The apparatus of claim 17, wherein housing unit comprises a power source to power the control system when the seal unit is not electrically connected to the control system, and wherein the power source of the control system is rechargeable by said power source in the seal unit when the seal unit is electrically connected thereto.

19. An apparatus comprising:

first means for housing a control system and for attaching to a door of a shipping container, wherein the first means comprises means for determining a position of the first means and means for wireless communicating information stored in the control system of the first means to a remote location;

second means for engaging with an element of the door of a shipping container and for electrically connecting with the control system of the first means;

wherein the control system in the first means being configured to detect a breach of the second means indicative of access being the shipping container.

20. The apparatus of claim 19, and further comprising means for sensing an intrusion into the shipping container, and wherein said control system generates a message for transmission to a remote location via said means for wireless communicating.

21. The apparatus of claim 19, wherein said first means further comprises means for capturing a digital image outside of said first means of a person attempting access into the container or interacting with said apparatus.

22. The apparatus of claim 19, wherein the second means comprises an elongated cable and one or more electrical conductors and/or optical fibers contained in the elongated cable, and wherein the control system monitors a signal representing a characteristic of the one or more electrical conductors and/or optical fibers to detect said beach.

23. The apparatus of claim 19, wherein said control system stores an identifier assigned to said first means and said second means comprises a memory that stores an identifier assigned to said second means.

24. A container monitoring system comprising an administrative facility and the apparatus of claim 19, wherein the administration facility communicates with the apparatus in order to track conditions of the apparatus including the geographical position of the apparatus and occurrence of said breach.

25. The system of claim 24, wherein the administration facility stores data containing identifiers for the first means and for the second means, and user party identifiers that are associated with said identifiers for the first means and the second means.
