Abstract

A detection system for an enclosed container includes many nanosensors for detecting materials harmful to human beings within an enclosed container and transmitting a signal representing a condition thereof. The nanosensors are carried on a carrier material, such as a corrugated sheet. At least one detection device detects a condition of the nanosensors and outputs a signal responsive thereto, which can be received by a monitoring system external to the container. Containers which have harmful materials within them can be inspected or stopped before entering the country.

Claims

1. A detection system for an enclosed container, comprising:

many nanosensors for detecting materials harmful to human beings within an enclosed container and transmitting a corresponding resonance frequency, the nanosensors being carried by a carrier material; and

at least one detection device which detects a condition of the nanosensors and outputs a signal responsive thereto.

2. The detection system of claim 1, wherein the carrier material is ridged.

3. The detection system of claim 1, wherein the carrier material is a sheet material.

4. The detection system of claim 1, wherein the carrier material is carried by at least one support member.

5. The detection system of claim 1, wherein the carrier material sandwiched between rigid support members.

6. The detection system of claim 4, wherein the carrier material and support members define through passages between them for passage of fluid therethrough.

7. The detection system of claim 1, wherein the nanosensors are applied to the carrier material by at least one of silk screen printing, ink jet printing, and electrophotography.

8. The detection system of claim 1, further comprising a strip and wherein the detection device and carrier material are supported on the strip.

10. The detection system of claim 8, wherein the radiation detection system comprises scintillators.

11. The detection system of claim 7, wherein the strip further comprises an adhesive for mounting the detection system to a wall of the container.

12. The detection system of claim 7, wherein the detection device includes at least one metal stud embedded in a sticky side of the strip for contacting walls of the container to facilitate and improve transmission of resonant frequencies from the detection device inside a container.

13. The detection system of claim 1, wherein the detection device comprises at least one of:

a sensor which detects the transmitted resonant frequencies; and

a transmitter which transmits signals in response to the detected transmitted resonant frequencies.

14. The detection system of claim 1, wherein the detection device includes an encrypted serial numbered (ESN) computer chip which stores and transmits information about an encrypted serial number that is specific to the one or more particular detection devices.

15. The detection system of claim 1, wherein the detection device includes a global positioning system computer chip for identifying at least one of origin and travel of the detection device and container to which the detection device is attached.

16. The detection system of claim 1, wherein the detection device includes a power source.

17. The detection system of claim 1, wherein the detection device is calibrated to produce and transmit a distinct resonant frequency which is independent of any other frequencies transmitted by the detection device.

18. The detection system of claim 1, wherein the nanosensors are designed to detect one or more harmful materials selected from the group consisting of harmful explosives, chemicals, biological materials, radioactive materials, and illegal drugs.

19. The detection system of claim 1, wherein at least some of the nanosensors are designed to detect heat.

20. The detection system of claim 1, in combination with a monitoring device for receiving signals from the detection device and translating such frequencies into digital readouts on the monitoring device and/or transmitting information about the containers based on the signals to a computer device or printer at a remote location.

21. The detection system of claim 1, further comprising a transponder mounted to a door of the container which transmits signals from the detection device to an external monitoring device remote from the container.

22. In combination, the detection system of claim 1 and an enclosed container to be monitored for said harmful materials.

23. The detection system of claim 21, wherein the container is a cargo container in which foreign products and foodstuffs are shipped into the United States of America.

24. In combination:

a) a cargo container in which any suitable cargo is placed for transport from one place to another place;

b) a detection system disposed in the container for detecting tampering with the container, the detection system including a nanonsensor assembly comprising a ridged carrier material supporting numerous nanosensors which are designed to transmit a predetermined frequency;

c) means of storing and transmitting information about the condition of the nanosensors and optionally a serial number specific to the detection system using an ESN computer chip; and

d) a power source for operating the detection system.

25. The combination of claim 24, further comprising a global positioning computer chip for identifying at least one of origin and travel of the container.

26. The combination of claim 24, further comprising means outside the container for receiving resonant frequencies transmitted from inside the container or signals generated by the detection system in response thereto.

27. A method for detecting harmful materials comprising:

forming a nanosensor assembly including positioning a carrier material supporting nanosensors adjacent a support member to provide a series of hollow passages through which detectable materials are carried by a through flow of air,

positioning the assembly in an enclosed container; and

monitoring signals output by the nanosensors in response to the detectable materials with a monitoring device external to the container.
