Abstract: The method includes first arranging a liquid storage portion to hold a liquid aerosol-forming substrate, second arranging a wick and an aerosol generator to communicate the liquid aerosol-forming substrate from the liquid storage portion and at least partially vaporize the liquid aerosol-forming substrate, third arranging a tilt sensor to sense an angle of orientation value of the liquid storage portion, and configuring at least one processor of an electrical circuit to monitor the angle of orientation value as sensed by the tilt sensor to determine a depletion value of the liquid aerosol-forming substrate based at least in part on the angle of orientation value, while the aerosol-generating device is in any physical orientation.

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: An aerosol-generating system may include a cartridge, a vaporiser section configured to receive the cartridge, and a power supply section configured to supply electrical power to the vaporiser section. The cartridge may include a cartridge housing containing a solid aerosol-forming substrate and defining a cartridge air inlet that extends through a wall portion of the cartridge housing. The vaporiser section may include a vaporiser housing containing an electric heater and a liquid aerosol-forming substrate and defining a vaporiser air outlet that extends through a wall portion of the vaporiser housing. The cartridge wall portion is configured to abut the vaporiser wall portion when the cartridge is received within the vaporiser section. The cartridge configured to be rotatable with respect to the vaporiser section to vary the amount of overlap between the cartridge air inlet and the vaporiser air outlet.

Abstract: An aerosol-generating system (includes a cartridge, a liquid aerosol-forming substrate, and an aerosol-generating device. The cartridge includes a cartridge housing and a solid aerosol-forming substrate. The aerosol-generating device includes a cavity configured to receive at least a portion of the cartridge, an airflow inlet, and an airflow sensor. The airflow sensor is in fluid communication with the airflow inlet and the cavity). The aerosol-generating device includes a bypass air inlet in fluid communication with the cavity, an electric heater configured to heat the liquid aerosol-forming substrate, a power supply, and a controller. The aerosol-generating system is configured so that the cartridge housing substantially prevents airflow through the bypass air inlet when the cartridge is received within the cavity.

Abstract: An element for an aerosol-generating system, a cartridge for an aerosol-generating system, and an aerosol-generating system, wherein the element, the cartridge and the aerosol-generating system each include a storage portion for storing an aerosol-forming substrate and a manually operated disabling mechanism for rendering the element, the cartridge, or the aerosol-generating system irreversibly inoperable. The element, the cartridge, and the aerosol-generating system may include an aerosol generator and one or more air passages. The disabling mechanism may be configured to render at least one of the storage portion, the aerosol generator, and the one or more air passages irreversibly inoperable.
