Abstract

Systems, methods, apparatuses, and computer readable media are disclosed for improving, in some examples, registration of radio frequency tags with a location system. Example embodiments may include a method for registering a participant with a radio frequency (RF) location tag. The method may include determining tag derived data from the one or more registered RF location tags, identifying at least one unregistered RF location tag, determining an identity of a participant for registration with the unregistered RF location tag based at least in part on the tag derived data from the one or more registered RF location tags, and registering the unregistered RF location tag with the participant.

First claim

That which is claimed:

1. A method for registering an unregistered radio frequency (RF) location tag carried by a participant using one or more registered RF location tags carried by the participant, the method comprising:
receiving first blink data from the one or more registered RF location tags;
determining first tag location data based on the first blink data received-from the one or more registered RF location tags;
receiving second blink data from the unregistered RF location tag;
determining second tag location data based on the second blink data received from the unregistered RF location tag;
determining, using a processor, an identity of the participant for registration with the unregistered RF location tag based at least in part on the first blink data received from the one or more registered RF location tags;
comparing the first tag location data and the second tag location data to a threshold value; and
registering the unregistered RF location tag with the participant when the comparison of the first tag location data to the second tag location data satisfies the threshold value.

2. The method of claim 1 , further comprising receiving tag registration information for the one or more registered RF location tags, wherein the identity of the participant is further determined based at least in part on the tag registration information.

3. The method of claim 1 , further comprising:
determining a first motion vector for the participant based on the first tag location data;
determining a second motion vector for the unregistered RF location tag based on the second tag location data; and
determining to register the unregistered RF location tag with the participant further based on comparing the first motion vector with the second motion vector.

4. The method of claim 1 , further comprising:
receiving a plurality of tag association models associated with a plurality of participants, wherein each tag association model comprises a number of RF location tags associated with each respective participant; and,
determining the identity of the participant based at least in part on the tag association model associated with the participant.

5. The method of claim 4 , wherein each tag association model further comprises one or more relative spatial locations between RF location tag locations associated with each respective participant, and wherein the method further comprises:
determining the identity of the participant based at least in part by comparing the second tag location data of the unregistered RF location tag with the first tag location data of the one or more of the registered RF location tags and further with the relative spatial locations of the RF location tag locations of the tag association model corresponding to the participant.

6. The method of claim 1 , wherein the first blink data comprises information sufficient to determine whether the one or more registered RF location tags is registered, and the method further comprises determining the identity of the participant based at least in part on determining that the participant has less than a minimum number of registered RF location tags registered to the participant.

7. The method of claim 1 , wherein the unregistered RF location tag comprises an ultra-wideband (UWB) transmitter.

8. The method of claim 7 wherein the UWB transmitter is configured to transmit a plurality of time of arrival (TOA) timing pulses.

9. The method of claim 7 wherein the UWB transmitter is configured to transmit an information packet comprising 112 bits.

10. An apparatus for registering an unregistered radio frequency (RF) location tag carried by a participant using one or more registered RF location tags carried by the participant, the apparatus comprising a processor coupled to a memory, the memory comprising instructions that, when executed by the apparatus, configure the apparatus to:
receive first blink data from the one or more registered RF location tags;
determine first tag location data based on the first blink data from the one or more registered RF location tags;
receive second blink data from the unregistered RF location tag;
determine second tag location data based on the second blink data from the unregistered RF location tag;
determine an identity of a participant for registration with the unregistered RF location tag based at least in part on the first blink data from the one or more registered RF location tags;
compare the first tag location data and the second tag location data to a threshold value; and
register the unregistered RF location tag with the participant when the comparison of the first tag location data to the second tag location data satisfies the threshold value.

11. The apparatus of claim 10 , wherein the apparatus is further configured to receive tag registration information for the one or more registered RF location tags, and wherein the identity of the participant is further determined based at least in part on the tag registration information.

12. The apparatus of claim 10 , wherein the apparatus is further configured to:
determine a first motion vector for the participant based on the first tag location data;
determine a second motion vector for the unregistered RF location tag based on the second tag location data; and
determine to register the unregistered RF location tag with the participant further based on comparing the first motion vector with the second motion vector.

13. The apparatus of claim 10 , further configured to:
receive a plurality of tag association models associated with a plurality of participants, wherein each tag association model comprises a number of RF location tags associated with each respective participant; and,
determine the identity of the participant based at least in part on the tag association model associated with the participant.

14. The apparatus of claim 13 , wherein each tag association model further comprises one or more relative spatial locations between RF location tag locations associated with each respective participant, and wherein the apparatus is further configured to:
determine the identity of the participant based at least in part by comparing the second tag location data of the unregistered RF location tag with the first tag location data of the one or more of the registered RF location tags and with the relative spatial locations of the RF location tag locations of the tag association model corresponding to the participant.

15. The apparatus of claim 10 , wherein the first blink data comprises information sufficient to determine whether the one or more registered RF location tags is registered, and the apparatus is further configured to determine the identity of the participant based at least in part on determining that the participant has less than a minimum number of registered RF location tags registered to the participant.

16. The apparatus of claim 10 , wherein the unregistered RF location tag comprises an ultra-wideband (UWB) transmitter.

17. The apparatus of claim 16 wherein the UWB transmitter is configured to transmit a plurality of time of arrival (TOA) timing pulses.

18. The apparatus of claim 16 wherein the UWB transmitter is configured to transmit an information packet comprising 112 bits.

19. A computer program product comprising a non-transitory computer readable storage medium for registering an unregistered radio frequency (RF) location tag carried by a participant using one or more registered RF location tags carried by the participant, the non-transitory computer
