Abstract

A robust, wireless sensor system providing a low cost method of tracking people such as sex offenders, child molesters, etc., after their release from prison or other confinement, which protects society from such individuals and lessens their ability to repeat such offenses. The system and method of the invention can also be used to locate kidnapped persons, people buried in snow avalanches, missing or dead soldiers, etc. The system utilizes RFID tags placed on people or in specified locations and RFID transmitters that can resonate with the tagged people or objects. Such a trigger recognition arrangement combined with communication of information from the triggering can be used to obtain a signal alerting the transmitter carrier that the tagged object or person is nearby. The triggering action can also initiate a sequence of information transfers in which the transmitter broadcasts to a central command that a particular transmitter is or was in proximity to a specific object or person, and allows the command center to order the dispatch of authorized personnel, such as policemen, military personnel, emergency rescue workers, etc. to the triggering location.

Claims

1. A wireless tracking system, comprising:

one or more objects or people tagged with RFID devices, TT,

an active RFID transmitter-receiver, AT, that can communicate with the TT'"'"'s when it comes in close proximity to them,

a transmitter adapted to send to a central command unit, a CC, a signal identifying the TT and the AT once they establish communication with each other,

a central command unit, CC, adapted to receive identifying information from the AT'"'"'s, compare the information to data bases, make proper conclusions and alert authorities of occurrence details, and

an authority entity or entities, AE, adapted to receive signals from the CC and dispatch response personnel to the location of the occurrence.

2. The system of claim 1 wherein the AT is attachable to a person.

3. The system of claim 1 wherein the AT is attachable to a person and is equipped with a tamper sensor so that if the AT is deactivated or removed in an unauthorized way, it alerts the CC.

4. The system of claim 1 wherein the power source of the AT is attachable to a person and alerts its carrier and/or the CC when available power gets low and the battery needs recharging.

5. The system of claim 1 wherein the TT and/or the AT are adapted to provide location information associated with an alarm.

6. The system of claim 1 further comprising a means of identifying the location, wherein said means comprise a global positioning system (GPS) embedded in the AT.

7. The system of claim 1 where at least one of the TT'"'"'s comprises a passive RFID.

8. The system of claim 1 where at least one of the TT'"'"'s comprises an active RFID.

9. The system of claim 1 wherein the signal from the AT is transmitted to the CC wirelessly directly or via one or more interim transfer stations or repeaters.

10. The system of claim 1 wherein the AT comprises:

a transmitter that connects the AT wirelessly, via a telephone line or via another form of hard wire to a central control room.

an active RFID source that continually interrogates and area close to the AT looking for other RFID devices,

an RFID receiving antenna that accepts the signal from the excited TT.

a temper-sensor that activates the transmitter if the AT is removed or tampered with, and

a battery alert to inform a wearer that his AT battery is approaching an exhausted state and needs to be replaced and alert the CC where the wearer is, the status of his battery and the need that for battery replacement, optionally with a further alert to the wearer that if the battery is not replaced within a predetermined time, then a further alarm may be issued and accompanied by dispatch of police authorities.

11. The system of claim 1 wherein the CC contains a data base containing relevant information of all potential offenders, as a Criminals Data Base (CDB).

12. The system of claim 1 wherein the CC contains a data base containing relevant information of all tags placed in various locations or on people, and relevant information associated with each TT, so that it can be made available to the EA when an alarm occurred, as a Target Tags Data Base (TTDB).

13. The system of claim 1 wherein the CC contains a data base containing the relevant information of all responsible parties associated with specific TT'"'"'s, as an Associates Data Base (ADB)

14. The system of claim 1 wherein the CC contains a data base containing a map of its jurisdiction area defining and associated AE'"'"'s with specific locations, and defining priorities or order of AEs to be called in a case of an alarm, as an Associates Map Data Base (AMDB).

15. The system of claim 1 wherein the CC contains a data base containing relevant information of all potential authorities and AE, their capabilities and specific responsibilities relative to specific potential victims and/or responsibility to specific potential crime locations, as a Police Data Base (PDB).

16. The system of claim 1 wherein the CC routinely polls some or all of the ATs associated with it to determine that they are functioning, their locations, the strength of their batteries and/or other relevant information.

17. The system of claim 1 wherein the CC contains an algorithm for associating a specific AE with specific locations in the CC jurisdiction area and having the ability to supply the AE with information on potential offenders, potential victims and other relevant information, as they are being dispatched to the alert location.

18. The invention of claim 1 wherein the CC contains an algorithm associating specific AT with specific locations in the CC jurisdiction area and having the ability to warn AEs that a potential offender is in a forbidden zone, and to alert a potential offender that he is in a forbidden zone and thus should leave before AE personnel enter said zone.

19. The system of claim 1 wherein the ATs are placed on known sex offenders or child molesters to permit them freedom while protecting the community.

20. The system of claim 1 wherein TT are adapted to be placed on a threatened victim to alert the AE and the potential victim that a threatening party came into close proximity to the threatened victim.

21. The system of claim 1 wherein TT is placed in specific locations in dwellings or work places or cars of a threatened victim or on other locations associated with the threatened victim to alert police and the threatened victim if a threatening party comes in a close proximity thereto.

22. The system of claim 1 wherein TT'"'"'s are placed on people and/or on their clothing, while present in a danger zone in which they are susceptible to being kidnapped, to permit search parties equipped with a TA to locate them.

23. The system of claim 1, where the TT'"'"'s are placed on soldiers, news reporters, or contractors to facilitate a search for them.

24. The system of claim 1 wherein the TT'"'"'s are placed on mountain climbers, skiers, or hikers to facilitate locating them when lost or isolated from discovery.

25. The system of claim 1 wherein the TT'"'"'s are placed on children to facilitate locating them when lost or missing.

26. The system of claim 1 wherein the TT'"'"'s are placed on persons in a nursing home to facilitate locating them when they are lost or missing.
