Abstract: The heating engine control circuit includes a rail converter circuit and a gate driver circuit. The rail converter circuit is configured to convert a power supply voltage into a power signal based on a vaping enable signal, the vaping enable signal being a pulse width modulated signal. The gate driver circuit includes an integrated gate driver. The integrated gate driver is configured to control application of power to a heater of the non-nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

Abstract: A non-nicotine pod assembly for a non-nicotine e-vaping device may include a pod body and a connector module. The pod body has an upstream end and a downstream end and is configured to hold a non-nicotine pre-vapor formulation. The upstream end of the pod body defines a cavity. The connector module is configured to be seated within the cavity of the pod body. The connector module may include an external face and a side face. The external face of the connector module includes at least one electrical contact and defines a pod inlet. The side face of the connector module defines at least one module inlet. The side face of the connector module faces a sidewall of the cavity in the pod body when the connector module is seated within the cavity.

Abstract: A capsule for an aerosol-generating device may include a housing defining inlet openings, outlet openings, and internal channels between the inlet openings and the outlet openings. The internal channels are configured to hold an aerosol-forming substrate. The housing is configured to facilitate a heating of the aerosol-forming substrate via conduction and/or convection so as to generate an aerosol.

Abstract: A method of controlling a heater of a nicotine e-vapor device includes detecting, from a removable pod included in the nicotine e-vapor device, power information indicating a first power level and a second power level; and supplying power to the heater based on the detected power information by determining a first amount of power based on the first power level, supplying the first amount of power to the heater during a first operation mode of the heater, determining a second amount of power based on the second power level, and supplying the second amount of power to the heater during a second operation mode of the heater, the second amount of power being higher than the first amount of power.
