Abstract

An intrusion detector for a vehicle, such as the trailer of a tractor-trailer combination. The detector, which is attachable to the vehicle, includes a carbon dioxide detector responsive to the concentration of carbon dioxide in a compartment of the vehicle. The intrusion detector generates an alarm if the carbon dioxide concentration in the compartment exceeds a predetermined level.

Claims

1. An intrusion detector for a vehicle, the detector being attachable to the vehicle, wherein the intrusion detector comprises a carbon dioxide detector responsive to the presence of carbon dioxide in a compartment of the vehicle, and wherein the intrusion detector is operable to generate an alarm if the concentration of carbon dioxide in the compartment exceeds a selected level.

3. An intrusion detector according to claim 1 wherein the intrusion detector is adapted to be mounted on the exterior of the vehicle and wherein a duct is provided whereby air from the compartment may be passed to the carbon dioxide detector.

4. An intrusion detector according to claim 3 and further including a fan adapted to pass air from the compartment to the carbon dioxide detector.

5. An intrusion detector according to claim 1, and wherein said detector includes a battery which is connectable to be charged from a power supply of the vehicle.

6. An intrusion detector according to claim 1, and wherein said selected level of carbon dioxide is at least 2000 ppm.

7. An intrusion detector according to claim 1, and wherein the alarm includes at least one of an audible alarm, a visual alarm, and the transmission of an alarm message.

8. An intrusion detector according to claim 1, and further including an auxiliary detector responsive to the presence of a person to the compartment.

9. An intrusion detector according to claim 8, and wherein the auxiliary detector comprises a PIR detector.

16. An intrusion detector according to claim 8, and wherein the auxiliary detector comprises a microwave detector.

17. An intrusion detector according to claim 6, and wherein said selected level of carbon dioxide is at least 2500 ppm.

18. An intrusion detector according to claim 6, and wherein said selected level of carbon dioxide is at least 3500 ppm.

19. In combination with a vehicle having a compartment, an intrusion detector attached to said vehicle, said intrusion detector including a carbon dioxide detector responsive to a predetermined concentration of carbon dioxide in said compartment for generating an alarm.

20. A vehicle with an intrusion detector, according to claim 19, and wherein said vehicle comprises a trailer for a tractor-trailer combination.

21. A vehicle with an intrusion detector, according to claim 19, wherein said intrusion detector is mounted on an exterior of said vehicle, and wherein said intrusion detector is connected through a duct to said compartment.

22. A vehicle with an intrusion detector, according to claim 21, and wherein said intrusion detector further includes a fan mounted to cause a flow of air from said compartment through said carbon dioxide detector.

23. A vehicle with an intrusion detector, according to claim 21, and wherein said predetermined carbon dioxide concentration is at least 2000 ppm.

24. A vehicle with an intrusion detector, according to claim 22, and wherein said predetermined carbon dioxide concentration is at least 2500 ppm.

25. A vehicle with an intrusion detector, according to claim 22, and wherein said predetermined carbon dioxide concentration is at least 3500 ppm.
