Abstract
An aerosol provision device includes a microphone configured to detect a flow of air in the device and to output corresponding airflow detection signals to control circuitry. The control circuitry is configured to determine a duration of an inhalation by a user of the aerosol delivery device based on the airflow detection signals received from the microphone.
Claims22
An aerosol provision device comprising:
- a microphone configured to detect a flow of air in the aerosol provision device and to output corresponding airflow detection signals to control circuitry;
- and
- control circuitry configured to determine a duration of an inhalation by a user of the aerosol delivery device based on the airflow detection signals received from the microphone.
The aerosol provision device of claim, wherein the control circuitry is configured to detect a first phase of the inhalation and a second phase of the inhalation based on the airflow detection signals, wherein the first phase of the inhalation occurs until the airflow detection signals are above a phase threshold, and the control circuitry is configured to alter the phase threshold based on the determined default inhalation behavior.
An aerosol provision system comprising:
- a microphone configured to detect a flow of air in the aerosol provision device and to output corresponding airflow detection signals to control circuitry;
- and
- control circuitry configured to determine a duration of an inhalation by a user of the aerosol provision device based on the airflow detection signals received from the microphone.
A method of determining a duration of an inhalation by a user of an aerosol provision device comprising:
- receiving airflow detection signals from a microphone configured to detect a flow of air in the aerosol provision device;
- and
- determining a duration of an inhalation by a user of the aerosol provision device based on the airflow detection signals received from the microphone.
A non-transitory computer readable storage medium comprising instructions which, when executed by a processor, cause the processor to perform a method comprising:
- receiving airflow detection signals from a microphone configured to detect a flow of air in the aerosol provision device;
- and
- determining a duration of an inhalation by a user of the aerosol provision device based on the airflow detection signals received from the microphone.
