Abstract
An aerosol generation system for generation of an aerosol from an aerosol-forming precursor includes an electrically operated heating system to heat the precursor to generate the aerosol; a flow path for transmission of flow, including the aerosol, to a user; the heating system arranged in fluid communication with the flow path; electrical circuitry to measure a change in a property associated with the heating system due to a cooling effect on the heating system from a user inhalation through the flow path, to determine a characteristic of the inhalation based on the measured property associated with the heating system, and to identify the user based on the determined characteristic.

An aerosol generation system for generation of an aerosol from an aerosol-forming precursor, the system comprising:
- an electrically operated heating system to heat said precursor to generate the aerosol;
- a flow path for transmission of flow to a user;
- wherein the heating system is arranged in fluid communication with the flow path;
- and
- electrical circuitry arranged to:
- measure a change in a property associated with the heating system due to a cooling effect on the heating system from a user inhalation through the flow path;
- determine a characteristic of the user inhalation based on the measured property associated with the heating system;
- and
- identify the user based on the determined characteristic.
A method of identifying a user of an aerosol generation system for generation of an aerosol from an aerosol-forming precursor, the aerosol generation system comprising an electrically operated heating system to heat said precursor to generate the aerosol, and a flow path for transmission of flow to the user, wherein the heating system is arranged in fluid communication with the flow path;
- the method comprising:
- measuring a change in a property associated with the heating system due to a cooling effect on the heating system from a user inhalation through the flow path;
- determining a characteristic of the user inhalation based on the measured property associated with the heating system;
- and
- identifying the user based on the determined characteristic.
