Abstract

A system for location of assets on a premises is described. The system uses identifiers attached to a group of one or more assets along with mobile sensor packages. Each mobile sensor package contains components for data processing, data exchange, and storage. The sensor package also contains a sensor for reading identifiers and a location tool. The mobile sensor packages are attached to each mover of assets on the premises.

Claims

1. A multi-level system for location of assets on a premises comprising:

identifiers attached to a group of one or more assets located on an enclosed interior area of the premises;

wherein said assets are undergoing motion; and

mobile sensor packages wherein each said mobile sensor package comprises data processing, data exchange, and storage components, a sensor for reading identifiers and each mobile sensor package further comprises a location tool within the premises;

wherein at least one mobile sensor package is attached to each mover of assets on the premises;

wherein said location tool comprises an ultra-wide band active tag which communicates with ultra-wide band readers located at fixed points within the interior of the premises; and

wherein said sensor packages collect information from said identifiers.

2. The system of claim 1 wherein said identifiers comprise passive RFID tags.

3. The system of claim 1 wherein said mobile sensor package reader of identifiers comprises an array of antennas for reading passive RFID tags.

4. The system of claim 3 wherein said array of antennas is constrained to read just RFID tags in a specific nearby location.

5. The system of claim 1 wherein said mobile sensor package provides to an external data store lists of assets being carried by the mover carrying said mobile sensor package.

6. The system of claim 5 wherein said external data store also comprises a list of a time and a location for each asset group.

7. The system of claim 1 wherein said data exchange system comprises a wireless link between each mobile sensor package and a location system.

8. The system of claim 7 wherein said system provides for current positions of assets within the premises by combining each mobile sensor package data storage contents using the wireless link of each mobile sensor package.

9. The system of claim 1 wherein the readers of ultra-wide band active tags are located in known locations within said premises.

10. The system of claim 1 wherein said location tool triangulates the location of each mobile sensor package while said mobile sensor package is in motion.

11. The system of claim 1 wherein said identifiers comprise bar codes, image detection, or combination of detection of unique identifiers.

12. A multi-level method of tracking contents of a premises, the method comprising:

attaching identifiers to a group of one or more assets located on an enclosed interior area of the premises;

wherein said identifiers comprise passive identifiers;

attaching mobile sensor packages to each mover of assets on the premises;

wherein each said mobile sensor package comprises data processing, data exchange, and storage components, a sensor for reading identifiers and each mobile sensor package further comprises a location tool within the premises;

wherein said location tool for each sensor package comprises an ultra-wide band active tag and wherein said premises further comprises readers of said ultra-wide band active tags at known locations;

taking an initial inventory of stationary assets within the premises;

moving assets within the premises only using movers which are equipped with mobile sensor packages; and

reading the identifiers on the assets while moving said assets by a mover, recording the location of each group of assets as each group of assets moves through the premises.

13. The method of claim 12 wherein said identifiers comprise passive RFID tags.

14. The method of claim 12 wherein said mobile sensor package reader of identifiers comprises an array of antennas for reading passive RFID tags.

15. The method of claim 14 wherein said array of antennas is constrained to read just RFID tags in a specific nearby location.

16. The method of claim 12 wherein said mobile sensor package provides to an external data store lists of assets being carried by the mover carrying said mobile sensor package.

17. The method of claim 16 wherein said data exchange system comprises a wireless link between each mobile sensor package and a location system.

18. The method of claim 12 wherein said data exchange system comprises a wireless link between each mobile sensor package and the location system.

19. The method of claim 12 wherein the readers of ultra-wide band active tags are located in known locations within said premises.

20. The method of claim 12 wherein said identifiers comprise bar codes, image detection, or combination of detection of unique identifiers.
