Abstract: A method of controlling a hot wire anemometer (HWA) of a non-nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the non-nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the non-nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the non-nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

Abstract: A device assembly includes a controller, which is configured to control the non-nicotine electronic vaping device to output an indication of a current level of the non-nicotine pre-vapor formulation in the non-nicotine reservoir of a non-nicotine pod assembly in response to determining that an aggregate amount of non-nicotine pre-vapor formulation drawn from the non-nicotine reservoir or an aggregate amount of vaporized non-nicotine pre-vapor formulation is greater than or equal to the at least one non-nicotine pre-vapor formulation level threshold.

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: At least one example embodiment provides s system for controlling a heater in a non-combustible aerosol-generating device. The system comprises a memory storing computer-readable instructions and a controller configured to execute the computer-readable instructions to cause the non-combustible aerosol-generating device to, detect an airflow in the non-combustible aerosol-generating device, apply a first power to the heater based on the detected airflow, apply a second power to the heater based on a target preheat temperature and the detected airflow being below an airflow threshold value, the application of the second power being after the application of the first power, and apply a third power to the heater based on the target preheat temperature and the detected airflow being below the airflow threshold value, the application of the third power being after the application of the second power, the third power being greater than the second power.
