Abstract: A aerosol-generating system includes a liquid storage portion, a liquid pressure sensor within the liquid storage portion, and a control unit that is in communication with the pressure sensor. The aerosol-generating system further includes an atmospheric pressure sensor in communication with the control unit. The atmospheric pressure sensor is configured to sense the atmospheric pressure of the environment. The control unit is configured to receive the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor. The control unit is further configured to determine the fill level of the liquid aerosol-forming substrate based on a comparison of the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor.

Abstract: An electrically operated aerosol-generating system may be configured to detect adverse conditions (e.g., a dry heater). The system may comprise an electric heater comprising at least one heating element for heating an aerosol-forming substrate, a power supply, and electric circuitry connected to the electric heater and to the power supply and comprising a memory. The electric circuitry may be configured to measure an initial electrical resistance (R1) of the electric heater; measure a subsequent electrical resistance of the electric heater after the measurement of the initial electrical resistance; determine the difference (ΔR) between the initial electrical resistance and the subsequent electrical resistance; determine that an adverse condition is present if the difference is greater than a maximum threshold value (ΔRmax) or less than a minimum threshold value (ΔRmin) stored in the memory; and control a power to the electric heater and/or provide an indication if the adverse condition is present.

Abstract: An aerosol-generating device includes an interface, one or more pairs of conductors, and electrical circuitry. The interface is configured to receive at least a portion of a consumable. The consumable comprises one or more conductive portions arranged to identify the consumable. The one or more pairs of conductors define at least a portion of one or more circuits. The one or more pairs of conductors are selectively electrically couplable with the one or more conductive portions of the consumable if the consumable is received by the interface. The electrical circuitry is configured to identify the consumable based on completion of the one or more circuits defined by the one or more pairs of conductors and the one or more conductive portions if the consumable is received by the interface.

Abstract: An aerosol-generating article may comprise a liquid storage portion containing a liquid aerosol-forming substrate, and a hydrochromic material provided on the liquid storage portion. The hydrochromic material has a first colour when in the presence of or when in contact with the liquid aerosol-forming substrate and a second colour when in the absence of or when not in contact with the liquid aerosol-forming substrate. An aerosol-generating system may comprise the aerosol-generating article, an aerosol-generating element, and an aerosol-generating device. An aerosol-generating device may comprise an electrical power supply, an electronic photosensor, and a controller configured to control a supply of electrical power from the electrical power supply based on a value of an optical property sensed with the electronic photosensor.

Abstract: Systems, devices, and methods may control total particulate matter (TPM) production based on air flow rate and TPM density. TPM density is a TPM production rate per flow rate of gas through an aerosol-generating device. The systems, devices, and methods may measure, or sample, air flow during a puff or draw on an aerosol-generating device. The aerosol-generating device may, in turn, adjust the production of the TPM based on the measured air flow rate and a selected, or desired, TPM density, which may be pre-set in the device and/or subsequently set as desired.
