Abstract

Apparatuses, systems, and/or methods for providing an induction heating system are disclosed. The induction heating system includes an induction power supply and an induction heating tool configured to receive induction-type power from the induction power supply through one or more ports. The ports may be part of the induction power supply and/or an associated junction box. The induction heating tool may include a heating coil attached to one or more plugs via one or more cables. The ports of the induction power supply and/or junction box are configured to receive the plugs of the induction heating tool. A communication device may be positioned adjacent the ports. The communication device may be configured to read data from one or more memory devices of the induction heating tool (e.g., in/on the plugs) via close proximity communication.

First claim

What is claimed is:

1. An induction heating system, comprising:
an induction power source configured to generate induction-type power;
an induction heating tool configured to use the induction-type power to perform a heating operation;
a memory device attached to the induction heating tool, wherein the memory device is configured to store data relating to the induction heating tool; and
a communication device associated with the induction power source, wherein the communication device is configured to read the data from the memory device using a close proximity communication protocol when the memory device is in close proximity, wherein the data comprises an amount of time the induction heating tool has been in use, and wherein a user interface is configured to deliver an alert in response to the amount of time meeting or exceeding a threshold.

2. The induction heating system of claim 1 , further comprising a port of the induction power source, or of a junction box in electrical communication with the induction power source, the port being configured for an electrical connection with the induction heating tool, the induction heating tool configured to receive the induction-type power through the electrical connection with the port, the communication device being retained proximate the port, and the memory device being attached to the induction heating tool such that the memory device is in close proximity to the communication device when the electrical connection is established between the induction heating tool and the port.

3. The induction heating system of claim 1 , wherein the memory device is an NFC tag, and the communication device is an NFC interrogator.

4. The induction heating system of claim 1 , wherein the memory device is an RFID tag, and the communication device is an RFID interrogator.

5. The induction heating system of claim 1 , wherein the induction heating tool includes an electrically conductive portion configured to conduct the induction-type power to perform the heating operation, the memory device being electrically insulated from the electrically conductive portion.

6. The induction heating system of claim 2 , further comprising control circuitry configured to
determine whether the electrical connection has been established between the induction heating tool and the port,
in response to determining the electrical connection has been established, track an amount of time the electrical connection between the induction heating tool and the port is maintained, the communication device being configured to update the data stored by the memory device, using the close proximity communication protocol, based on the amount of time.

7. A method, comprising:
storing data relating to an induction heating tool in a memory device attached to the induction heating tool, the data comprising an amount of time the induction heating tool has been in use:
reading the data from the memory device via close proximity communication using a communication device associated with an induction power supply, wherein the induction power supply is configured to generate induction-type power and provide the induction-type power to the induction heating tool, the induction heating tool configured to use the induction-type power to perform a heating operation; and
delivering an alert in response to the amount of time the induction heating tool has been in use meeting or exceeding a threshold.

8. The method of claim 7 , further comprising writing data to the memory device via close proximity communication using the communication device.

9. The method of claim 7 , wherein the memory device is an RFID tag.

10. The method of claim 7 , wherein the communication device is an RFID interrogator.

11. The method of claim 7 , wherein the induction heating tool includes an electrically conductive portion configured to conduct the induction-type power to perform the heating operation, the memory device being electrically insulated from the electrically conductive portion.

12. The method of claim 7 , wherein the memory device is an NFC tag.

13. The method of claim 7 , wherein the communication device is an NFC interrogator.

14. An induction heating system, comprising:
an induction power source configured to generate induction-type power;
an induction heating tool configured to use the induction-type power to perform a heating operation;
a port of the induction power source, or of a junction box in electrical communication with the induction power source, the port being configured for an electrical connection with the induction heating tool, and the induction heating tool configured to receive the induction-type power through the electrical connection with the port;
a memory device attached to the induction heating tool, wherein the memory device is configured to store data relating to the induction heating tool; and
a communication device associated with the induction power source, the communication device being retained proximate the port, and the memory device being attached to the induction heating tool such that the memory device is in close proximity to the communication device when the electrical connection is established between the induction heating tool and the port, wherein the communication device is configured to read the data from the memory device using a close proximity communication protocol when the memory device is in close proximity.

15. The induction heating system of claim 14 , further comprising control circuitry configured to:
determine whether the electrical connection has been established between the induction heating tool and the port, and
in response to determining the electrical connection has been established, track an amount of time the electrical connection between the induction heating tool and the port is maintained, the communication device being configured to update the data stored by the memory device, using the close proximity communication protocol, based on the amount of time.

16. The induction heating system of claim 14 , wherein the memory device is an NFC tag, and the communication device is an NFC interrogator.

17. The induction heating system of claim 14 , wherein the memory device is an RFID tag, and the communication device is an RFID interrogator.

18. The induction heating system of claim 14 , wherein the data comprises an amount of time the induction heating tool has been in use, and wherein a user interface is configured to deliver an alert in response to the amount of time meeting or exceeding a threshold.

19. The induction heating system of claim 14 , wherein the induction heating tool includes an electrically conductive portion configured to conduct the induction-type power to perform the heating operation, the memory device being electrically insulated from the electrically conductive portion.
