Abstract

A system and method for acquisition management of subject position information that utilizes radio frequency identification (RF ID) to store position information in position tags. Tag programmers receive position information from external positioning systems, such as the Global Positioning System (GPS), from manual inputs, such as keypads, or other tag programmers. The tag programmers program each position tag with the received position information. Both the tag programmers and the position tags can be portable or fixed. Implementations include portable tag programmers and fixed position tags for subject position guidance, and portable tag programmers for collection sample labeling. Other implementations include fixed tag programmers and portable position tags for subject route recordation. Position tags can contain other associated information such as destination address of an affixed subject for subject routing.

Claims

1. A method of providing position guidance to a subject with respect to an area, the method comprising:

receiving via radio frequency signals position information from a position tag associated with a fixed location in the area, the position tag programmed via radio frequency signals with the position information by a remote programmer; and

directing movement of the subject within the area based upon the received position information.

2. The method of claim 1, further comprising sending information request signals from a point of origination, and

responding to the signals by the position tag when the position tag is located within a predetermined maximum distance from the point of origination.

3. The method of claim 1 wherein the received position information includes position coordinates relative to other fixed positions within the area.

4. The method of claim 1 wherein directing movement of the subject within the area further includes providing instructions intelligible to a human.

5. The method of claim 1 wherein directing movement of the subject within the area further includes providing instructions intelligible to a robot.

6. The method of claim 1 wherein directing movement of the subject within the area further includes providing instructions intelligible to a vehicle.

7. The method of claim 1 wherein the received position information includes information from the United States Department of Defense managed Global Positioning System (GPS).

8. The method of claim 1 wherein the position tag further stores a timestamp.

9. The method of claim 1 wherein the position tag is a beam powered passive tag.

10. The method of claim 1 wherein the position tag is a battery-powered semi-passive tag.

11. The method of claim 1, further comprising:

positioning the position tag in a stationary position.

12. A method of routing a subject from an origination to a given destination through a network of nodes connected together by paths, the method comprising:

programming by a remote programmer via radio frequency signals a position tag to store position information related to the given destination;

affixing the position tag to the subject;

requesting the position information of the given destination stored in the position tag when the subject reaches a node;

receiving a continuous wave backscatter signal from the position tag including the position information; and

when the node is not the given destination according to the received position information, sending the subject to another node according to the received position information.

13. The method of claim 12 wherein the sending is further according to principles of operations research.

14. The method of claim 12, further comprising sorting subjects according to position information related to destinations of the subjects received via radio signals from position tags attached to the subjects.

15. The method of claim 12 wherein the position tag further stores information for at least one of origination, sender, and receiver.

16. The method of claim 12 wherein the position tag is a beam powered passive tag.

17. The method of claim 12 wherein the position tag is a battery-powered semi-passive tag.

18. The method of claim 12 wherein the position information is received by the remote programmer from a Global Positioning System (GPS).

19. A method of providing position guidance to a subject with respect to an area, the area having position tags dispersed therein, the method comprising:

programming by a remote programmer via radio frequency signals each of the position tags with position information associated with its fixed location, the position information including position coordinates relative to other fixed locations within the area;

receiving via radio frequency signals position information from a position tag associated with a fixed location in the area; and

directing movement of the subject within the area based upon the received position information.

20. A position guidance system to provide guidance to a subject with respect to an area, the system comprising:

means for programming a position tag associated with a fixed location in the area with position information via radio frequency signals;

means for extracting position information from radio frequency signals sent by the position tag; and

means for directing movement of the subject within the area based upon the extracted position information.

21. The system of claim 20 wherein the means for programming is a remote programmer.

22. The system of claim 20, further comprising:

means for sending information request signals from a point of origin; and

means for responding to the radio frequency signals sent by the position tag.

23. The system of claim 22 wherein the means for responding is configured to respond when the position tag is located within a predetermined distance from the point of origin.

24. The system of claim 20 wherein the extracted position information includes position coordinates relative to other fixed positions within the area.

25. The system of claim 20 wherein the means for directing movement comprises means for providing instructions intelligible to a human.

26. The system of claim 20 wherein the means for directing movement comprises means for providing instructions intelligible to a robot.

27. The system of claim 20 wherein the means for directing movement comprises means for providing instructions intelligible to a vehicle.

28. The system of claim 20 wherein the extracted position information includes information from the United States Department of Defense Global Positioning System (GPS).

29. A routing system to route a subject from an origination to a given destination through a network of nodes connected together by paths, the system comprising:

remote means for programming, via radio frequency signals, a position tag affixed to the subject with position information related to the destination, the position tag being configured to store the position information;

means for requesting the stored destination information from the position tag when the subject reaches a node;

means for receiving a continuous wave backscatter signal from the position tag, the signal including the position information; and

means for selectively sending the subject to another node based on the received position information.

30. The system of claim 29 wherein the means for selectively sending is configured to employ principles of operations research.

31. The system of claim 29, further comprising:

means for sorting subjects according to position information related to destinations of the subjects received via radio frequency signals from position tags attached to the subjects.

32. The system of claim 29 wherein the position tag is configured to store information for at least one of origination, sender and receiver.

33. A system for providing guidance to a subject with respect to an area, comprising:

a plurality of position tags dispersed within respective fixed locations within the area;

remote means for programming, via radio-frequency signals, the position tags with position information associated with their respective fixed location, the position information including position coordinates relative to other fixed locations within the area;

means for receiving, via radio-frequency signals, position information from a position tag in the plurality of position tags; and

means for directing movement of the subject within the area based on the received position information.
