Abstract

An apparatus monitors the movement of a person through an exit. The apparatus comprises an electronic article surveillance system adapted to generate an electromagnetic field at the exit and a tag worn by the person. The tag is responsive to the electromagnetic field. It is caused to alarm upon departure of the person from the exit. The tag is further provided with an alarm means for alarming the electronic article surveillance system.

Claims

1. A tag adapted to be worn by a person, for monitoring movement of the person through an exit having an electronic article surveillance system, comprising:

a. antenna means for receiving an electromagnetic field generated by said electronic article surveillance system;

b. alarm means for sounding an alarm;

c. detecting means for detecting said electromagnetic field, said detecting means causing said alarm means to sound an alarm upon detection of said electromagnetic field;

d. power means, for powering said tag;

e. housing means for encasing said antenna means, said detecting means, said alarm means, and said power means; and

f. attaching means for attaching said housing means to said person,

whereby upon detection of said electromagnetic field, said detecting means causes said alarm means to sound an alarm.

2. An apparatus, for monitoring movement of a person through an exit, comprising:

a. an electronic article surveillance system for generating an electromagnetic field at said exit and detecting a preselected disturbance in said electromagnetic field produced by passage of an article surveillance system tag therethrough; and

b. a tag worn by said person, said tag being powered and having an alarm means responsive to said electromagnetic field for generating a signal that reproduces said preselected disturbance;

whereby said tag will alarm and trigger said electronic article system alarm on departure of said person from said exit.

3. A tag adapted to be worn by a person, for monitoring the movement of the person through an exit having an electronic article surveillance system that generates an electromagnetic field at said exit and detects a preselected disturbance in said electromagnetic field produced by passage of an article surveillance system tag therethrough, comprising:

a. antenna means for receiving the electromagnetic field generated by said electronic article surveillance system;

b. alarm means for sounding an alarm;

c. detecting means for detecting said electromagnetic field, said detecting means causing said alarm means to sound an alarm upon detection of said electromagnetic field;

d. power means, for powering said tag;

e. housing means for encasing said antenna means, said detecting means, said alarm means, and said power means; and

f. attaching means for attaching said housing means to said person;

said tag further comprising;

g. generating means responsive to said electromagnetic field for generating a signal that reproduces said preselected disturbance; and

h. switching means for switching said antenna between said detecting means and said generating means,

whereby upon detection of said electromagnetic field, said detecting means causes said alarm means to sound an alarm and said switching means to connect said antenna to said generating means, causing said electronic article surveillance system to alarm.

4. A tag as recited by

claim 3

, further comprising resetting means for resetting said alarm.

5. A tag as recited by

claim 3

, wherein said battery is rechargeable.

6. A tag as recited by

claim 3

, further comprising:

a. generating means for generating a signal from an electronic article surveillance marker; and

b. transmitting antenna means for transmitting said mimicking signal,

whereby upon detection of said electromagnetic field, said detecting means causes said alarm means to sound an alarm and said generating means to generate said signal to said transmitting antenna means causing said electronic article surveillance system to alarm.

7. A tag, as recited by

claim 3

, wherein said person is a vulnerable person.

8. A tag, as recited by

claim 3

, wherein said person has an infirmity.

9. A tag, as recited by

claim 8

, wherein said person has a mental disability.

10. A tag, as recited by

claim 9

, wherein said person is a hospital patient.

11. A tag, as recited by

claim 9

, wherein said person is an Alzheimer'"'"'s patient.

12. A tag, as recited by

claim 3

, wherein said person is a low risk inmate of a detention center.

13. A method, for detecting the movement of a person through an exit provided with an electronic article surveillance system that generates an electromagnetic field at said exit and detects a preselected disturbance in said electromagnetic field produced by passage of an article surveillance system marker therethrough, comprising the steps of:

a. attaching to said person a tag responsive to the electromagnetic field generated by said electronic article surveillance system at said exit;

b. receiving said electromagnetic field; and

c. sounding an alarm on said tag in response to application of said electromagnetic field and generating a signal that reproduces said preselected disturbance, thereby triggering an alarm on said electronic article surveillance system.

14. A tag, as recited by

claim 13

, wherein said person is a vulnerable person.

15. A tag, as recited by

claim 13

, wherein said person has an infirmity.

16. A tag, as recited by

claim 15

, wherein said person has a mental disability.

17. A tag, as recited by

claim 16

, wherein said person is a hospital patient.

18. A tag, as recited by

claim 16

, wherein said person is an Alzheimer'"'"'s patient.

19. A tag, as recited by

claim 13

, wherein said person is a low risk inmate of a detention center.
