Abstract

An RFID-based induction heating/vending system for quickly and efficiently heating, vending, and recollecting stadium seats (10) or other objects. The system includes a plurality of objects each including an induction-heatable body (22), a charging/vending station (12) for heating and vending the objects; a self-serve warming station (14) that may be used by consumers to reheat their objects; and a check-out station (16) that automatically collects objects from consumers after use.

Claims

1. A method of vending thermal seats, the method comprising the steps of:

providing a plurality of thermal seats, each seat having an RFID tag associated therewith, and each seat including —

an induction-heatable body including a plurality of discrete induction-heatable elements, each including graphite material, and heat retentive synthetic resin material located adjacent the elements and operable to serve as a heat sink upon magnetic induction heating of the elements, the elements characterized by the property of substantially simultaneous heating thereof by an externally applied magnetic field, and

a cover surrounding the body and including a cushioning component over the body and presenting a seating surfaces;

heating one of the seats for a customer;

storing customer-specific information in the RFID tag of the seat; and

providing a check-out station for return of the seat after the customer'"'"'s use thereof, the station including a seat-receiving housing and an RFID tag reader operable to obtain information from the RFID tag when the customer deposits the seat in the housing and, in response to the obtainment of information, generating a receipt for the customer confirming return of the seat.

2. The method as set forth in claim 1, further including the step of reading information from the RFID tag of the seat to obtain information to be used when heating the seat.

3. The method as set forth in claim 1, wherein the heating step is performed with a magnetic induction heater.

4. The method as set forth in claim 1, further including the step of providing a self-serve warming station for use by the customer in reheating the seat after the seat has been vended.

5. A system for heating, vending, and collecting thermal seats, the system comprising:

a plurality of magnetic induction-heatable thermal seats, each of the thermal seats including —

an induction-heatable body including a plurality of discrete induction-heatable elements, each including graphite material, and heat retentive synthetic resin material located adjacent the elements and operable to serve as a heat sink upon magnetic induction heating of the elements, the elements characterized by the property of substantially simultaneous heating thereof by an externally applied magnetic field, and

a cover surrounding the body and including a cushioning component over the body and presenting a seating surface;

a charging/vending station for heating and vending the thermal seats; and

a check-out station for collecting the thermal seats after they have been used by consumers.

6. The system as set forth in claim 5, each of the thermal seats further including an RFID tag operable to store information thereon.

7. The system as set forth in claim 6, the charging/vending station including —

a plurality of magnetic induction cooktops for heating the thermal seats,

an RFID reader for reading information from the RFID tags of the thermal seats, and

a credit card reader in communication with the RFID readers for delivering customer information to the RFID readers to be written to the RFID tags.

8. The system as set forth in claim 6, the check-out station including —

a substantially enclosed housing having at least one chute formed therein for receiving thermal seats returned by consumers,

an RFID reader positioned in the vicinity of the chute to read the RFID tags of the returned thermal seats,

a control unit for obtaining information from the RFID reader, and

a receipt printer coupled with the control unit for printing receipts when the thermal seats are returned.

9. The system as set forth in claim 5, further including a self-serve warming station including a plurality of magnetic induction cooktops for use by consumers to reheat thermal seats after the seats have been vended.

10. A method of vending thermal seats, the method comprising the steps of:

placing a thermal seat having an RFID tag associated therewith on a magnetic induction heater, wherein each of the seats includes —

an induction-heatable body including a plurality of discrete induction-heatable elements, each including graphite material, and heat retentive synthetic resin material located adjacent the elements and operable to serve as a heat sink upon magnetic induction heating of the elements, the elements characterized by the property of substantially simultaneous heating thereof by an externally applied magnetic field, and

a cover surrounding the body and including a cushioning component over the body and presenting a seating surface;

reading the RFID tag with an RFID tag reader associated with the heater;

heating the seat based at least partially upon information read from the RFID tag;

writing customer information onto the RFID tag with the RFID tag reader; and

removing the thermal seat from the magnetic induction heater and giving it to a consumer.

11. The method as set forth in claim 10, further including the step of reading information from the RFID tag of the seat to obtain information to be used when heating the seat.

12. The method asset forth in claim 10, wherein the heating step is performed with a magnetic induction heater.

13. The method as set forth in claim 10, further including the step of providing a self-serve warming station for use by the customer in reheating the seat after the seat has been vended.
