RFID device with two-stage power harvesting
Disclosed is a method of gathering data from a hybrid RFID chip to determine usage of an item or article of clothing using a mobile device like a phone, laptop, or tablet. The hybrid RFID chip consists of a processor, a memory, a radio transceiver, a power harvesting antenna, and an impedance circuit that converts ambient radio frequency (RF) energy to electrical energy. The RFID chip receives a first power level from ambient RF energy and periodically broadcasts an identity. The mobile device can receive the broadcast identity, store the identity, transmit the identity and location to a remote server, and receive a notification message from the remote server. The remote serve can determine usage of the item or article of clothing by comparing current records to previous records of RFID chip identity, location, and mobile device application identity.
1. A method of determining usage of an article based on communicating data from a User Equipment (UE), comprising:
receiving, by a monitoring application executing on a User Equipment (UE), a Radio Frequency Identification (RFID) message from a plurality of RFID tags;
storing an application data package, by the monitoring application, in non-transitory memory on the UE;
establishing a communication session by the monitoring application with a remote application executing on a remote network via a wireless connection with a wireless protocol to a wireless receiver communicatively coupled to the remote network;
sending the RFID message from the monitoring application to the remote application;
writing a current data record, by the remote application, into non-transitory memory on the remote network, wherein the current data record comprises an application data set, a current data hash, and a previous data hash;
determining an event record, by the remote application, by comparing the application data set of the current data record to an application data set of a previous data record; and
sending an event notification, by the remote application, to the monitoring application executing on the UE.
2. The method of claim 1 , wherein the wireless receiver is an access point or an access node.
3. The method of claim 1 , wherein the application data package comprises an RFID message, an application identification, a date stamp, a timestamp, and a location data set by the UE.
4. The method of claim 1 , wherein the RFID message comprise at least one of an RFID identification and an RFID information.
5. The method of claim 1 , wherein the remote network comprises a virtual network function located on a slice of a 5G network.
6. The method of claim 1 , wherein the current data hash is determined by a hash function of the application data set by the remote application, wherein the current data hash is written to the current data record by the remote application, wherein the previous data hash is a current data hash from a previous data record, wherein the previous data hash is written to the current data record by the remote application, and wherein the current data record is sequential to the previous data record.
7. The method of claim 1 , wherein the plurality of RFID tags comprise hybrid RFID chips that operate in two different modes.
8. The method of claim 1 , wherein at least one of the plurality of RFID tags is retained in an article.
9. The method of claim 8 , wherein the article is made from textile fabric.
10. The method of claim 9 , wherein the event record comprises an indication of a usage of the article.
11. A User Equipment (UE), comprising:
at least one processor;
at least one non-transitory memory; and
a monitoring application stored in the at least one memory, that when executed by the at least one processor:
receive a Radio Frequency Identification (RFID) message from a plurality of RFID tags,
store an application data package in the at least one non-transitory memory on the UE,
establish a communication session with a remote application executing on a remote network via a wireless connection with a wireless protocol to a wireless receiver communicatively coupled to the remote network,
send the RFID message to the remote application, and
write a current data record into non-transitory memory on the remote network, wherein the current data record comprises an application data set, a current data hash, and a previous data hash, and wherein the remote application determines an event record by comparing the application data set of the current data record to an application data set of a previous data record, and
receives an event notification from the remote application.
12. The UE of claim 11 , wherein the wireless receiver is an access point or an access node.
13. The UE of claim 11 , wherein the application data package comprises an RFID message, an application identification, a date stamp, a timestamp, and a location data set by the UE.
14. The UE of claim 11 , wherein the RFID message comprise at least one of an RFID identification and an RFID information.
15. The UE of claim 11 , wherein the remote network comprises a virtual network function located on a slice of a 5G network.
16. The UE of claim 11 , wherein the current data hash is determined by a hash function of the application data set by the remote application, wherein the current data hash is written to the current data record by the remote application, wherein the previous data hash is a current data hash from a previous data record, wherein the previous data hash is written to the current data record by the remote application, and wherein the current data record is sequential to the previous data record.
17. The UE of claim 11 , wherein the plurality of RFID tags comprise hybrid RFID chips that operate in two different modes.
18. The UE of claim 11 , wherein at least one of the plurality of RFID tags is retained in an article.
19. The UE of claim 18 , wherein the article is made from textile fabric.
20. The UE of claim 18 , wherein the event record comprises an indication of a usage of the article.
