Abstract

A tamper-proof motion and tampering alarm for a pneumatic tired vehicle consists of a motion detector, tampering detectors, radio transmitter, and power supply. All of these are mounted inside the pressurized tire of the vehicle. Any unauthorized motion or tampering with the tire will cause the alarm to be activated at a distant remote site by way of radio signal through the dielectric tire.

The control unit consists of a radio receiver, alarm, system interfaces, and power supply. The system can be enabled and securely disenabled by use of prearranged and encrypted radio signals.

Claims

1. A tampering and theft alarm system for a vehicle having at least a pneumatic tire, said system comprising:

(a) a vehicle unit mounted within a pneumatic tire of a vehicle and including means for detecting an unauthorized movement of the vehicle and generating an alarm signal in response to the unauthorized movement of the vehicle, a first transmitter for transmitting the alarm signal, a first receiver for receiving an enabling or disenabling signal, means responsive to the enabling or disenabling signal for enabling or disenabling, respectively, said detecting means, and a first power source operably connected to said detecting means, said first transmitter, said first receiver and said enabling or disenabling means;

(b) a control unit remote from the vehicle and including a second receiver for receiving the alarm signal from said first transmitter, alarm means operably connected to said second receiver for being responsive to the received alarm signal, a second transmitter for transmitting the enabling or disenabling signal to said vehicle unit, and a second power source operably connected to said second receiver, said alarm means, and said second transmitter;

(c) whereby when the detecting means is enabled by the enabling signal from said control unit and when said detecting means detects unauthorized movement of the vehicle, said vehicle unit transmits an alarm signal to said control unit thereby activating said alarm means and warning a person in the vicinity of said control unit of the unauthorized movement of the vehicle.

2. A system as in claim 1, wherein:

(a) said detecting means includes a motion sensor.

3. A system as in claim 1, wherein:

(a) said detecting means includes a vibration sensor.

4. A system as in claim 1, wherein:

(a) said detecting means includes an internal pressure sensor.

5. A system as in claim 1 wherein:

(a) said detecting means includes a motion sensor and a plurality of vibration and internal pressure sensors.

6. A system as in claim 1, wherein:

(a) said enabling and disenabling means includes a processor.

7. A system as in claim 1, wherein:

(a) said vehicle unit includes means for informing a user when said detecting means is enabled or disenabled.

8. A system as in claim 1 wherein:

(a) said control unit includes means for encrypting the disenabling signal; and

(b) said vehicle unit includes means for deciphering the encrypted disenabling signal.

9. A system as in claim 1, wherein:

(a) said first power source includes a rechargeable battery.

10. A system as in claim 9, wherein:

(a) said first power source includes a generator for charging said battery.

11. A system as in claim 1, wherein:

(a) said alarm means includes an audible alarm.

12. A tampering and theft alarm system for a vehicle having at least a pneumatic tire, said system comprising:

(a) at least one alarm sensor disposed within a pneumatic tire of a vehicle for detecting an unauthorized movement of the vehicle and for generating an alarm signal in response to the unauthorized movement of the vehicle;

(b) a first processor disposed within the tire and operably connected to said at least one alarm sensor for enabling or disenabling said alarm sensor in response to an enabling or disenabling signal, respectively;

(c) a first transmitter disposed within the tire and operably connected to said first processor for transmitting the alarm signal when said first processor determines that the alarm sensor is enabled;

(d) a first receiver disposed within the tire and operably connected to said first processor for receiving the enabling or disenabling signal;

(e) a rechargeable battery disposed within the tire and operably connected to said at least one alarm sensor, said first transmitter, said first receiver and said first processor;

(f) a control unit remote from the vehicle and including a second receiver for receiving the alarm signal from said first transmitter, an alarm operably connected to said second receiver and responsive to the received alarm signal, a second processor for generating the enabling or disenabling signal, a second transmitter for transmitting the enabling or disenabling signal to said first receiver, and a power source operably connected to said second receiver, said alarm, said second transmitter, and said second processor;

(g) whereby when said at least one alarm sensor is enabled by the enabling signal from said control unit and when said alarm sensor senses the unauthorized movement of the vehicle, said first transmitter transmits an alarm signal to said control unit, thereby activating said alarm and warning a person in the vicinity of said control unit of the movement of the vehicle.

13. A system as in claim 12, wherein:

(a) said at least one alarm sensor includes a motion sensor.

14. A system as in claim 12, wherein:

(a) said at least one alarm sensor includes a vibration sensor.

15. A system as in claim 12, wherein:

(a) said at least one alarm sensor includes an internal pressure sensor.

16. A system as in claim 12, and including:

(a) a plurality of said at least one alarm sensor including a motion sensor and a plurality of vibration and internal pressure sensors.

17. A system as in claim 12, wherein:

(a) said second processor includes means for encrypting the disenabling signal; and

(b) said first processor includes means for deciphering the encrypted disenabling signal.

18. A system as in claim 12, and including:

(a) a counterweight disposed within the tire for balancing the tire.

19. A system as in claim 12, and including:

(a) a generator for charging said battery.

20. A system as in claim 12, wherein:

(a) said alarm includes an audible alarm.
