Abstract
A temperature-regulating induction heating system is provided which comprises an induction heater (,) having apparatus (,) for receiving RFID transmissions and an induction heatable object (,) with an RFID tag (,). The heater (,) includes a component (,) for generating a magnetic field, control circuitry including a microprocessor (,) coupled with the component (,) for selectively initiating and terminating generation of a magnetic field; the receiving apparatus (,) provides information to the microprocessor (,) causing initiation of a heating algorithm for the object (,). In preferred forms, the tag (,) and apparatus (,) are designed for two-way information transfer, thereby permitting continuous updating of the information carried by tag (,). In this way, if induction heating of the object (,) is interrupted, it maybe resumed to nevertheless achieve a desired regulation temperature. Advantageously, the RFID tag (,) and apparatus (,) operate during intermittent interruption of the primary magnetic field of the heater (,) to eliminate transmission interference. The tag (,) may be equipped with one or more thermal switches (,) to provide better temperature control.
