The present disclosure relates to a heating system comprising: a heating arrangement for heating a process medium; an inverter configured to receive an input direct-current voltage from a power supply and to produce an intermediate alternating-current voltage; a transformer configured to receive the intermediate alternating-current voltage produced by the inverter and to supply an output alternating-current voltage to the heating arrangement; a sensor arrangement configured to generate a first sensor output signal indicative of a thermodynamic parameter of the process medium or the heating arrangement; and a controller configured to control the inverter based on the first sensor output signal.

A cartridge for an aerosol-generating system includes a sensor including a capacitor with a first capacitor plate and a second capacitor plate, a storage portion for storing an aerosol-forming substrate, and a vaporizer. The storage portion is between the first capacitor plate and the second capacitor plate. The permittivity of the liquid storage portion changes upon a change of the volume f the liquid aerosol-forming substrate held in the liquid storage portion. The sensor is configured to measure the capacitance of the capacitor. The measured capacitance relates to a corresponding permittivity of the aerosol-forming substrate held in the storage portion so that the amount of the volume of the aerosol-forming substrate held in the storage portion is determinable from the measured capacitance.

An aerosol generating apparatus comprises: a power source; a load configured to have a resistance value that varies according to a temperature and generate an aerosol by atomizing an aerosol source or heating a flavor source when supplied with power from the power source; a sensor configured to include a resistor connected in series to the load and output a measurement value that is a current value of a current flowing through the resistor or a voltage value of a voltage applied to the resistor; and a control unit configured to control power supply from the power source to the load and receive output from the sensor, wherein the resistor has a resistance value that is set such that responsiveness of a change in the measurement value to a change in a temperature of the resistance value belongs to a prescribed range.

Features relating to a vaporizer body are provided. The vaporizer body may include an outer shell that includes an inner region defined by an outer shell sidewall. A support structure is configured to fit within the inner region of the outer shell. The support structure includes a storage region defined by a top support structure, a bottom support structure, a bottom cap, and a gasket. An integrated board assembly is configured to fit within the storage region of the support structure. The integrated board assembly may include a printed circuit board assembly formed of multiple layers that form a rigid structure and that include an inner, flexible layer. A first antenna is integrated at a proximal end of the flexible layer, and a second antenna is integrated at a distal end of the flexible layer.

An electronic stove incorporates a cylindrical outer shell and a concentric copper heater core. A foil heater surrounds the copper heater core and a heater control PCB carried in the outer shell is connected to the foil heater. A battery assembly has a cylindrical second outer shell carrying a battery pack. A power controller carried in the second outer shell is connected to the battery pack. A connector carriage is engaged between the battery assembly and cylindrical outer shell, extending through the shell of the battery assembly and received in the cylindrical outer shell aligned proximate a lower surface of the first outer shell whereby the lower surfaces of the first outer shell and the second outer shell are in planar alignment. A first contact set of a connector is connected to the heater control PCB. A second contact is connected to the power controller.
