Abstract

The present invention provides a method and system for determining a near-field communication interaction in a wireless tracking mesh network. The present invention preferably utilizes near-field communication devices in conjunction with tracking tags to transmit signals for reception by sensors stationed throughout a facility which form a mesh network and forward the signals to an information engine for analysis. Bearers of the near-field communication devices preferably include individuals, objects, assets and rooms of the facility.

Claims

1. A system utilizing near-field communications, the system comprising:

a mesh network comprising a plurality of sensors located in a facility for infrastructure-based real-time location tracking of objects and users in the facility, each of the plurality of sensors communicating with other sensors of the plurality of sensors utilizing a medium range wireless communication format, wherein each of the plurality of sensors operates in a geo-spatially fixed physical location in the facility;

a plurality of near-field communication devices, each of the plurality of near-field communication devices operating on a low power short-range wireless communication format and a medium range wireless communication format which is different than the low-power short-range wireless communication format, each of the plurality of near-field communication devices comprising a transceiver for transferring interaction data from one near-field communication device to another near-field communication device when the near-field communication devices are within a predetermined distance of each other, and a transceiver for transmitting a signal to at least one of the plurality of plug-in sensors, the signal comprising the interaction data and positioning data; and

an information engine in communication with the mesh network, the information engine processing the interaction data and positioning data.

2. The system according to claim 1 wherein the near-field communication data comprises a number of previous interactions between the near-field communication devices within a predetermined time period.

3. The system according to claim 1 wherein a bearer of a near-field communication device is at least one of a medical professional, a patient, an asset, an object, an area of the facility, or a host for a tag.

4. The system according to claim 1 wherein the interaction data is used to authenticate a user for access to at least one of or a combination of a computer, a medical equipment, a protected area of the facility, a medication drawer, or a patient'"'"'s room.

5. The system according to claim 1 wherein the interaction data comprises at least one of or a combination of a previous location of the first bearer, a previous location of the second bearer, a current location of the first bearer, a current location of the second bearer, and a number of other objects located near the interaction.

6. A system for determining a business relationship between individuals within a facility, the system comprising:

a plurality of first near-field communication devices, each of the plurality of first near-field communication devices having bearer of the near-field communication device, each of the plurality of first near-field communication devices operating on a low power short-range wireless communication format and a medium range wireless communication format which is different than the low-power short-range wireless communication format;

a plurality of second near-field communication devices, each of the plurality of second near-field communication devices representing an object, each of the plurality of second near-field communication devices operating on a low power short-range wireless communication format and a medium range wireless communication format which is different than the low-power short-range wireless communication format;

a mesh network comprising a plurality of sensors located in a facility for infrastructure-based real-time location tracking of objects and users in the facility, each of the plurality of sensors communicating with other sensors of the plurality of sensors utilizing a medium range wireless communication format, wherein each of the plurality of sensors operates in a geo-spatially fixed physical location in the facility; and

an information engine in communication with the mesh network, the information engine obtaining data on a near-field communication interaction between either plurality of first near-field communication devices or at least one first near-field communication devices and a second object, the near-field communication interaction comprising a position location of the interaction and a duration of the interaction.

7. The system according to claim 6 wherein the second object is fixed or mobile.

8. The system according to claim 6 wherein the near-field communication data comprises a number of previous interactions between the near-field communication devices within a predetermined time period.

9. The system according to claim 6 wherein a bearer of a near-field communication device is at least one of a medical professional, a patient, an asset, an object, an area of the facility, or a host for a tag.

10. The system according to claim 6 wherein a near-field communication interaction occurs when the near-field communication devices are within a predetermined distance of each other.

11. The system according to claim 6 wherein the near-field communication interaction data further comprises a number of previous interactions between the first person and the second person within a predetermined time period.

12. The system according to claim 6 wherein each of the first plurality of near-field communication devices is mounted on a corresponding identification card or is an identification card.

13. The system according to claim 6 wherein the near-field communication interaction data further comprises at least one of or a combination of a previous location of the first object, a current location of the first object, a previous location of the second object, a current location of the second object, and the number of other objects located near the interaction.

14. A method for determining a business relationship between individuals within a facility, the method comprising:
