    Abstract: An electrically operated aerosol generating system may include a storage portion configured to store an aerosol forming substrate, at least one heating element configured to heat the aerosol forming substrate, a sensor configured to detect an activation of the system, a clock, and electric circuitry connected to the sensor. A usage parameter associated with operation of the system may be measured and compared, to a threshold value. A usage profile of the system may be determined based on the comparison. Such operations may be repeated at different times of day. An operating mode of the system may be selectively executed based on the determined usage profile associated with the current time of day. A monitoring procedure may be ended when the measured usage parameter exceeds a threshold value, and the duration of the monitoring procedure may be compared to a threshold duration to determine the usage profile.

    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: A cartridge for an aerosol-generating system includes a sensor including a capacitor with a first capacitor plate and a second capacitor plate, a storage portion for storing an aerosol-forming substrate, and a vaporizer. The storage portion is between the first capacitor plate and the second capacitor plate. The permittivity of the liquid storage portion changes upon a change of the volume f the liquid aerosol-forming substrate held in the liquid storage portion. The sensor is configured to measure the capacitance of the capacitor. The measured capacitance relates to a corresponding permittivity of the aerosol-forming substrate held in the storage portion so that the amount of the volume of the aerosol-forming substrate held in the storage portion is determinable from the measured capacitance.

    Abstract: An aerosol-generating device comprises a device housing comprising a first receiving chamber configured to receive and accommodate a first consumable and a second receiving chamber configured to receive and accommodate a second consumable. The device further comprises a power source in an internal space defined by the device housing and a controller configured to control aerosolization of an aerosol-forming substrate in a consumable in one of the first receiving chamber and in the second receiving chamber. At least the second receiving chamber includes electrical contacts configured to be detachably connected to a battery based on the separate power source being in the second receiving chamber such that the electrical contacts provide additional power from the separate power source to the aerosol-generating device.
