Abstract

A portable alarm system includes a cigarette lighter socket mount which is useful to deploy a flexible beam structure in cantilever. An electrical board mounted eccentrically from the other end of the beam structure then provides the torsional and bending motions that are inducted in the course of illegal entry, these motions then being sensed by tank circuits connected to corresponding comparators. The output of each comparator is then combined in a logical AND and OR combination that is manually selected by a switch to turn on a sending unit that then communicates with a remote device like a pager.

Claims

1. An alarm system deployable from the cigarette lighter socket of a motor vehicle and conformed to sense motions imparted to said vehicle in the course of an intrusion and to issue an alarm signal to a remote paging unit, comprising:

a flexible beam structure deployable in cantilever from said lighter socket and including a magnetic portion adjacent said lighter socket; and

an electrical assembly secured to the free end of said beam structure and including a tank circuit means deployed in inductive proximity with said magnet to sense the movement of said electrical assembly relative said magnet, said electrical assembly further including a remote sending unit operatively connected to said tank circuit means for issuing said alarm signal upon the exceedance of said movement above a selected level.

2. Apparatus according to claim 1, wherein:

said movement of said electrical assembly includes at least a bending mode and a torsional mode each of a fundamental frequency different from the other; and

said tank circuit means includes individual tank circuits each conformed to sense a the exceedance of the amplitudes of the respective one of said fundamental frequencies of each said modes.

3. Apparatus according to claim 2, further comprising:

logic means interposed between said tank circuit means and said remote sending unit for logically combining the exceedances sensed by said individual tank circuits.

4. Apparatus according to claim 3, wherein:

said logic means is conformed to combine said exceedances in a logical AND combination.

5. Apparatus according to claim 3, wherein:

said logic means is conformed to combine said exceedances in a logical OR combination.

6. Apparatus according to claim 3, wherein:

said logic means is conformed to combine said exceedances in a logical AND and a logical OR combination.

7. Apparatus according to claim 6, further comprising:

a manually operable selection switch interposed between said logic means and said remote sending unit for accommodating manual selection of either one of said logical AND or said logical OR combinations.

8. Apparatus according to claim 1, wherein:

said magnetic portion includes an electromagnet.

9. An alarm system deployable for charging from an electrical outlet and conformed to sense motions imparted to a secured container in the course of an intrusion and to issue an alarm signal to a remote paging unit, comprising:

a flexible beam structure deployed in cantilever and including a magnetic portion adjacent one end thereof;

an electrical assembly secured to the other end of said beam structure and including a tank circuit means deployed in inductive proximity with said magnet to sense the movement of said electrical assembly relative said magnet, said electrical assembly further including a remote sending unit operatively connected to said tank circuit means for issuing said alarm signal upon the exceedance of said movement above a selected level; and

electric power storage means connected to said electrical assembly and conformed for connection to said electrical outlet.

10. Apparatus according to claim 9, wherein:

said movement of said electrical assembly includes at least a bending mode and a torsional mode each of a fundamental frequency different from the other; and

said tank circuit means includes individual tank circuits each conformed to sense a the exceedance of the amplitudes of the respective one of said fundamental frequencies of each said modes.

11. Apparatus according to claim 10, further comprising:

logic means interposed between said tank circuit means and said remote sending unit for logically combining the exceedances sensed by said individual tank circuits.

12. Apparatus according to claim 11, wherein:

said logic means is conformed to combine said exceedances in a logical AND combination.

13. Apparatus according to claim 11, wherein:

said logic means is conformed to combine said exceedances in a logical OR combination.

14. Apparatus according to claim 11, wherein:

said logic means is conformed to combine said exceedances in a logical AND and a logical OR combination.

15. Apparatus according to claim 14, further comprising:

a manually operable selection switch interposed between said logic means and said remote sending unit for accommodating manual selection of either one of said logical AND or said logical OR combinations.

16. Apparatus according to claim 9, wherein:

said magnetic portion includes an electromagnet.
