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.

Abstract: A vapor generator assembly for an e-vaping device may include a reservoir configured to hold a pre-vapor formulation, a vaporizer assembly configured to heat pre-vapor formulation drawn from the reservoir to form a vapor, and an air intake assembly configured to direct ambient air into the vaporizer assembly. The air intake assembly may at least partially define an air inlet that extends at least partially around an outer surface of the vapor generator assembly. The air inlet may be an arcuate air inlet or an annular air inlet. The air intake assembly may at least partially define an inlet channel extending from the air inlet into an interior of the vapor generator assembly to at least partially establish fluid communication between the arcuate air inlet and the vaporizer assembly. The inlet channel may extend coaxially in relation to a longitudinal axis of the vapor generator assembly.

Abstract: A non-nicotine pod assembly includes a non-nicotine reservoir to hold non-nicotine pre-vapor formulation, and a heater configured to vaporize non-nicotine pre-vapor formulation drawn from the non-nicotine reservoir. A device body is configured to engage with the non-nicotine pod assembly, and includes a controller. The controller is configured to cause the device body to detect a fault event at the non-nicotine electronic vaping device, classify the fault event as one of a plurality of types of fault events, and perform at least one consequent action based on the classification of the fault event.

Abstract: A non-nicotine e-vaping device may include a device body configured to receive a non-nicotine cartridge. The non-nicotine cartridge includes a non-nicotine pre-vapor formulation, a wick, and an integral heater-thermocouple. The wick is configured to transport the non-nicotine pre-vapor formulation by capillary action. The integral heater-thermocouple includes a first segment made of a first alloy and a second segment made of a second alloy. The device body includes a power supply, at least one sensor, and a controller. The power supply is configured to deliver electrical energy to the integral heater-thermocouple to heat the non-nicotine pre-vapor formulation to generate a non-nicotine vapor. The at least one sensor is configured to measure a voltage difference between the first segment and the second segment of the integral heater-thermocouple during such heating. The controller is configured to adjust the electrical energy to the integral heater-thermocouple based on the measured voltage difference.

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.

Abstract: A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.
