Abstract

A container has a base, sides and a top, the base, sides and top together defining a void within which items can be located in use, an electromagnetic shield fully surrounding at least part of the void to provide an electromagnetic shield between an exterior of the container and items located within the said part of the void, an antenna located within the said part of the void and a signal generator connected to the antenna and operable to apply a signal to the antenna to cause the transmission of an impeding signal within the said part of the void to impede the reception of signals transmitted from locations external to the container by items located within the said part of the void.

Claims

1. A container comprising a base, sides and a top, the base, sides and top together defining a void within which items can be located in use, an electromagnetic shield fully surrounding at least part of the void to provide the electromagnetic shield between an exterior of the container and items located within the said part of the void, an antenna located within the said part of the void and a signal generator connected to the antenna and operable to apply a signal to the antenna to cause a transmission of an impeding signal within the said part of the void to impede a reception of signals transmitted from locations external to the container by items located within the said part of the void.

2. A container according to claim 1, wherein the container comprises an airfreight container.

3. A container according to claim 2, wherein the container comprises a unit load device.

4. A container according to claim 1, wherein the sides and top of the container are rigid.

5. A container according to claim 1, wherein at least one of the sides is of a flexible material.

6. A container according to claim 1, wherein the electromagnetic shielding layer is applied to a surface of, or contained within, each of the sides, the top and the base.

7. A container according to claim 1, wherein a material of the sides, base and top serves as the shield.

8. A container according to claim 7, wherein the material comprises aluminum.

9. A container according to claim 1, wherein all parts of the shield layer are electrically connected to one another.

10. A container according to claim 1, wherein the signal generator is located within the container.

11. A container according to claim 1 and further comprising an internal power supply operable to supply power to the signal generator.

12. A container according to claim 11, wherein the power supply comprises a rechargeable battery.

13. A container according to claim 1, and further comprising a control panel accessible from the exterior of the container for controlling an operation of the signal generator.

14. A container according to claim 1, wherein the base, sides and top of the container are of materials selected to provide ballistics protection.
