A method for sensing a container includes: charging an induction heating circuit; sensing a current applied to the induction heating circuit, converting a current value of the current into a first voltage value; comparing the first voltage value with a resonance reference value; generating a resonance of the current; sensing a resonant current generated in the induction heating circuit; converting the resonant current into a second voltage value; comparing the second voltage value with a count reference value; generating one or more output pulses; comparing a count of the one or more output pulses with a reference count, or comparing an on-duty time of the one or more output pulses with a reference time; and based on (i) the comparison of the count with the reference count or (ii) the comparison of the on-duty time with the reference time, determining whether an object is present on a working coil.

Various smart package configurations may include a package intelligence and communication module (PICM) intelligently interacting with smart heating appliances and users. A thermodynamic load profile may correlate thermodynamic response characteristics of the package and be stored in or associated with a unique identifier in the PICM.

Conductors for use in heating systems are provided. The conductors are configured to have an extended current path for the current and increased resistance as seen by the current. The heating system may be an induction system. For example, the conductor may comprise a conductive material having a surface which faces an induction coil of an oscillating circuit. This surface may have a predetermined pattern of peaks and valleys. The peaks and valleys form a non-linear current path for the induced current when exposed to an electromagnetic field generated by the oscillating circuit. Other conductors such as a heat pipe may be used. The pipe may have walls with varying thicknesses over its length. The varying thicknesses may include a first thickness and a second thickness which alternate. The heat pipe may be used in an induction or direct contact heating system where AC is directly applied to the pipe.

A method for controlling an induction heating device includes supplying current from a D.C. power supply into a resonant load and emitting the current from the resonant load. The current is directionally conducted from the output node of the resonant load to a switching node downstream from the output node. The current conducted through the resonant load is controlled with a switching device.

A liquid heating device, for use with an induction hob, comprises a liquid heating vessel and a ferromagnetic heating plate (5) arranged to be located inside the vessel adjacent to the base (3) of the vessel.
