Abstract

A device and method for protecting personal property. The device includes a movement detection system and an alarm adapted to signal when the device has moved beyond a predetermined position from a reference point.

Claims

1. An alarm system, comprising:

a motion detector adapted to measure acceleration;

a controller adapted to calculate displacement of said motion detector from a reference point based at least in part on the acceleration of said motion detector; and

an alarm adapted to transmit a signal when said motion detector has moved beyond a predetermined position from the reference point.

2. The system of claim 1, wherein said controller is adapted to dynamically determine the displacement of said motion detector from the reference point.

3. The system of claim 1, wherein said motion detector includes a MEMS sensor arrangement.

4. The system of claim 1, wherein the predetermined position forms at least a portion of a sphere around the reference point and said controller is adapted to activate said alarm when said motion detector moves beyond the sphere.

5. The system of claim 1, wherein the predetermined position is generally in a single plane containing the reference point.

6. The system of claim 1, wherein said alarm is adapted to transmit a light signal.

7. The system of claim 1, wherein said alarm is adapted to transmit an audio signal.

8. The system of claim 1, wherein said motion detector, said controller and said alarm are physically connected to one another.

9. The system of claim 1, wherein said system is formed as a self-contained unit, further comprising a connector for attaching said unit to an object.

10. The system of claim 1, further comprising a biometric reader adapted to arm said alarm.

11. A container, comprising:

a body having a storage compartment; and

a movement detection system having a motion detector, a controller adapted to calculate displacement of said body from a reference point based at least in part on acceleration of said body, and an alarm adapted to transmit a signal when said body has moved beyond a predetermined position from the reference point.

12. The container of claim 11, wherein said movement detection system is integrally formed with said body.

13. The container of claim 11, further comprising a biometric reader adapted to arm said alarm.

14. A method for alerting a person to movement of an object beyond a preset boundary, comprising:

measuring acceleration of the object from an initial reference point to at least in part determine the displacement of the object from the initial reference point;

comparing the displacement of the object relative to the preset boundary; and

producing a signal if the object crosses the preset boundary.

15. The method of claim 14, wherein the step of measuring includes dynamically measuring the acceleration of the object from the initial reference point.

16. The method of claim 14, further comprising re-setting the boundary.

17. The method of claim 14, wherein the object is a container.

18. The method of claim 14, wherein the preset boundary is at least in part spherical.

19. The method of claim 14, wherein the step of measuring includes measuring generally only along a single plane.

20. The method of claim 14, wherein the step of producing a signal includes producing an audio signal.
