Abstract: An electrically operated aerosol-generating system may include a liquid storage portion configured to store a liquid from which aerosol may be generated, an electric heater, a capillary wick extending between the liquid storage portion and the electric heater and configured to convey liquid from the liquid storage portion to the electric heater and electric circuitry connected to the electric heater. The electric circuitry may be configured to: activate the electric heater for a first heating time period in response to an input to vaporize liquid in the capillary wick, activate the electric heater for a second heating time period upon the elapse of a first cooling time period after the first heating time period, record a temperature measurement of the electric heater during the second heating time period, and determine an amount of liquid in the liquid storage portion based on the temperature measurement.

Abstract: An aerosol-generating system includes a cartridge and an aerosol-generating device configured to receive the cartridge. The cartridge includes a cartridge housing and a cartridge aerosol-forming substrate within the cartridge housing. The cartridge housing has a first end, a second end, a first side between the first end and the second end, and at least one aperture on the first side. The aerosol-generating device includes a device housing, a liquid aerosol-forming substrate, an electric heater, a power supply, and a controller. The device housing defines a cavity, a cavity air inlet, and a cavity air outlet. The cavity is configured to receive the cartridge such that an airflow from the cavity air inlet to the cavity outlet flows through the cartridge via the at least one aperture during an operation of the aerosol-generating system.

Abstract: The aerosol-generating device includes a housing, a mouthpiece on an end of the housing, a first and second receiving chamber defined within the housing, where the first and second receiving chambers receive and accommodate a first and second consumable. A selection member is arrangeable in a first position and a second position, where the first position establishes a first airflow passageway that traverses through the first receiving chamber while circumventing the second receiving chamber, and the second position establishes a second airflow passageway that traverses through the second receiving chamber while circumventing the first receiving chamber. The method includes providing at least two consumables in a housing, establishing an airflow through a selected one of the at least two consumables while circumventing the airflow from passing through a non-selected one of the at least two consumables, and guiding the airflow to an outlet opening of a mouthpiece.

Abstract: A vapor-generating system includes a cartridge, a vapor-generating device and a piercing element. The cartridge includes a cartridge housing configured to hold a solid vapor-forming substrate within the cartridge housing interior, a liquid storage housing configured to hold a liquid vapor-forming substrate within the liquid storage housing interior, and a frangible seal on the liquid storage housing. The vapor-generating device includes a device housing at least partially defining a cavity, an electric heater, and a power supply. The piercing element is configured to pierce the frangible seal of the cartridge to expose the liquid storage housing interior to be in fluid communication with the electric heater based on the vapor-generating device coupling with the cartridge such that the device housing at least partially receives the cartridge into the cavity. The electric heater is located externally from the piercing element.

Abstract: A cartridge for an aerosol-generating system includes a liquid storage portion configured to store a liquid aerosol-forming substrate. The liquid storage portion includes one or more flexible walls and is configured to change at least one of the shape and the size of the liquid storage portion upon a change of the volume of the liquid aerosol-forming substrate held in the liquid storage portion. The cartridge includes a sensor configured to detect data of a physical property. The data relates to at least one of a corresponding shape and a corresponding size of the liquid storage portion so that the volume of the liquid aerosol-forming substrate held in the liquid storage portion is determinable from the measured data.
