Abstract

A security system for infants having a tuned fixed frequency coil affixed to an infant'"'"'s diaper. A detector for detecting when the tuned coil is in physical proximity or the absence of physical proximity to the detector. An alarm system is in communication with the detector to indicate when the coil is detected by the change in proximity of the infant by the monitoring of the location of the coil.

Claims

1. A surreptitious security system for infants comprising:

tuned coil means inconspicuously affixed to the diaper of an infant;

detector means for detecting when said tuned coil means affixed to the infant is in physical proximity to said detector means; and

alarm means for indicating when said detector means has detected said tuned coil means.

2. The invention claimed in claim 1, wherein said tuned coil means is affixed to the infant'"'"'s diaper.

3. The invention claimed in claim 2, wherein said tuned coil means affixed to the infant'"'"'s diaper is disposable.

4. The invention claimed in claim 2, wherein said tuned coil means is adhesively affixed to the infant'"'"'s diaper in an inconspicuous manner.

5. The invention claimed in claim 1, wherein said security system is used in a hosptial.

6. The invention claimed in claim 5, wherein said detector means is positioned at entrances and exits of the hospital.

7. The invention claimed in claim 1, wherein said alarm means emits an audible sound.

8. The invention claimed in claim 1, wherein said alarm means is a visual indicator.

9. A surreptitious security system for infants comprising:

sensor means affixed to the garment of an infant;

detector means for detecting when said sensor means is not in physical proximity to said detector means; and

alarm means for indicating when said detector means has detected when said sensor means is not in physical proximity to said detector means.

10. The invention claimed in claim 9, wherein the sensor means is affixed to the infant'"'"'s diaper.

11. The invention claimed in claim 10, wherein said sensor means affixed to the infant'"'"'s diaper is disposable.

12. The invention claimed in claim 10, wherein said sensor means is adhesively affixed to the infant'"'"'s diaper.

13. The invention claimed in claim 12, wherein said sensor means is adhesively affixed to the infant'"'"'s diaper in an inconspicuous manner.

14. The invention claimed in claim 9, wherein the security system is used in a hospital.

15. The invention claimed in claim 14, wherein said detector means is positioned at points of ingress and egress of the hospital.

16. The invention claimed in claim 9, wherein said alarm means emits an audible sound.

17. The invention claimed in claim 9, wherein said alarm means is a visual indicator.

18. A surreptitious security system for humans wearing clothing for use in a building, comprising:

a sensor means in a packet affixed to the clothing of a human, said packet positioned to the clothing in an inconspicuous location;

detector means for detecting the proximity to said sensor means affixed to the clothing of humans; and

alarm means in communication to said detector means indicating that the sensor means in said packet affixed to the humans is in proximity to said detector means.

19. A surreptitious security system for humans wearing clothing for use in a building, comprising:

sensor means in a packet affixed to the clothing of a human, said packet positioned to the clothing in an inconspicuous location;

detector means for detecting the proximity to said sensor means affixed to the clothing of the human; and

alarm means in communication to said detector means indicating that the sensor means in said packet affixed to the human is in proximity to said detector means.

20. An apparatus for detecting the movement of an infant within a predetermined area using a sensing system that causes an alarm, comprising:

detectable means inconspicuously affixed to the diaper of an infant for triggering the sensing system and causing the alarm when the detectable means enters the predetermined area.

21. An apparatus for detecting the movement of an infant within a predetermined area using a sensing system that causes an alarm, comprising:

detectable means inconspicuously affixed to the diaper of an infant for triggering the sensing system and causing the alarm when the detectable means leaves the predetermined area.
