Abstract

A method of controlling access to a movable container, the method comprising controllably locking the container using an electronically actuated locking mechanism; storing in a memory a desired geographical location; determining the geographical location of the container; and enabling the locking mechanism to unlock the container if the determined geographical location matches the desired geographical location. A secure cargo transportation system comprises a vehicle including an enclosure having an opening; a door movable relative to the opening between a closed position, wherein the door restricts access to the enclosure; and an open position; an electronically actuable lock configured to selectively lock or unlock the door relative to the enclosure; a memory supported by the vehicle and configured to store a location coordinate; and a global positioning system supported by the vehicle and coupled to the memory and to the lock, and configured to enable the lock to unlock the door if the vehicle is within a predetermined distance of the location coordinate.

Claims

1. A method of controlling access to a movable container by a processor coupled to the movable container, the method comprising:

controllably locking the container using an electronically actuated locking mechanism in response to a command from the processor;

storing in a memory a desired geographical location in response to a command from the processor;

determining the geographical location of the container;

comparing, in the processor, the geographical location of the container and the desired geographical location; and

enabling the locking mechanism to unlock the container in response to the processor determining that the determined geographical location is within a predetermined distance from the desired geographical location.

2. A method in accordance with claim 1 wherein the step of determining the geographical location of the container comprises using a global positioning system.

3. A method in accordance with claim 2 wherein the global positioning system is movable with the container.

4. A method in accordance with claim 2 wherein the global positioning system is in communication with the memory and the locking mechanism.

5. A method in accordance with claim 2 wherein the global positioning system communicates with the locking mechanism via radio frequency to enable the locking mechanism to unlock the container if the determined geographical location matches the desired geographical location.

6. A method in accordance with claim 2 wherein the global positioning system is electrically wired to the locking mechanism.

7. A method in accordance with claim 1 and further comprising, before, the storing step, the step of receiving the desired geographical location via wireless communication.

8. A method in accordance with claim 1 and further comprising, before the storing step, the step of receiving the desired geographical location via microwave.

9. A method in accordance with claim 1 and further comprising, before the storing step, the step of receiving the desired geographical location via radio frequency.

10. A method in accordance with claim 1 wherein the step of storing in a memory a desired geographical location comprises storing coordinates of at least three geographical points, and wherein the step of enabling the locking mechanism to unlock the container if the determined geographical location matches the desired geographical location comprises enabling the locking mechanism to unlock the container if the determined geographical location falls within an area defined by the coordinates.

11. A method in accordance with claim 1 wherein the step of storing in a memory a desired geographical location comprises storing data representing a point, and storing data representing a radius, and wherein the step of enabling the locking mechanism to unlock the container if the determined geographical location matches the desired geographical location comprises enabling the locking mechanism to unlock the container if the determined geographical location falls within an area defined within a radius about the point corresponding to the stored radius.

12. A method in accordance with claim 1 wherein the step of determining the geographical location is repeated multiple times.

13. A method in accordance with claim 1 wherein the step of determining the geographical location is repeated periodically.

14. A method of controlling access to a movable container, the method comprising:

using an electronically actuated locking mechanism to lock the container;

storing in memory a plurality of geographical areas through which it is desired that the container travel;

logging the geographical location of the container at each of a plurality of different times; and

enabling the locking mechanism to unlock the container if the container passed through each of the geographical areas stored in the storing step.

15. A method in accordance with claim 14 wherein the storing step further comprises defining an order of geographical areas, and wherein the step of enabling the locking mechanism to unlock the container comprises enabling the locking mechanism to unlock the container if the container passed through each of the geographical areas in the defined order.

16. A method in accordance with claim 14 wherein the storing step further comprises defining an order of geographical areas, including defining a final destination geographical area, and wherein the step of enabling the locking mechanism to unlock the container comprises enabling the locking mechanism to unlock the container if the container passed through each of the geographical areas in the defined order and is in the final destination geographical area.

17. A secure cargo transportation system comprising:

a vehicle including an enclosure having an opening;

a door movable relative to the opening between a closed position, wherein the door restricts access to the enclosure, and an open position;

an electronically actuable lock configured to selectively lock or unlock the door relative to the enclosure;

a global positioning system supported by the vehicle and coupled to the memory and to the lock, and configured to enable the lock to unlock the door if the vehicle is within a predetermined distance of the location coordinate.

18. A system in accordance with claim 17 and further comprising a wireless receiver supported by the vehicle and coupled to the memory and configured to transfer to the memory a location coordinate received from a remote transmitter.

19. A system in accordance with claim 17 wherein the electronically actuable lock is actuable in response to a digital key.

20. A system in accordance with claim 17 wherein the global positioning system includes the memory.

21. A system in accordance with claim 17 wherein the global positioning system communicates with the locking mechanism via radio frequency to enable the lock to unlock the door if the vehicle is within a predetermined distance of the location coordinate.

22. A system in accordance with claim 17 wherein the global positioning system is electrically hardwired to the locking mechanism.

23. A system in accordance with claim 17 and further comprising a microwave receiver supported by the vehicle and coupled to the memory and configured to transfer to the memory a location coordinate received via microwave from a microwave transmitter.

24. A system in accordance with claim 17 wherein the global positioning system comprises a processor configured to determine if the vehicle is within a predetermined distance of the location coordinate.

25. A secure cargo transportation system comprising:

a vehicle including an enclosure having an opening;
