Power Control For An Aerosol Delivery Device
An aerosol delivery device is provided. The aerosol delivery device includes a power source, an aerosol production component, a sensor to produce measurements of atmospheric air pressure in an air flow path through at least one housing, and a switch coupled to and between the power source and the aerosol production component. The aerosol delivery device also includes processing circuitry that determines a difference between the measurements of atmospheric air pressure and a reference atmospheric air pressure. Only when the difference is at least a threshold difference, the processing circuitry outputs a signal to cause the switch to switchably connect and disconnect an output voltage from the power source to the aerosol production component to adjust power provided to the aerosol production component to a power target that is variable according to a predetermined relationship between the difference and the power target.

- 1. An aerosol delivery device comprising:
at least one housing; and within the at least one housing, a power source configured to provide an output voltage; an aerosol production component powerable to produce an aerosol from an aerosol precursor composition; a sensor configured to produce measurements of atmospheric air pressure in an air flow path through the at least one housing; a switch coupled to and between the power source and the aerosol production component; and processing circuitry coupled to the sensor and the switch, and configured to at least:
determine a difference between the measurements of atmospheric air pressure from the sensor, and a reference atmospheric air pressure; and only when the difference is at least a threshold difference,
output a signal to cause the switch to switchably connect and disconnect the output voltage to the aerosol production component to power the aerosol production component for an aerosol-production time period, the switch caused to switchably connect and disconnect the output voltage to adjust power provided to the aerosol production component to a power target that is variable according to a predetermined relationship between the difference and the power target.
- 12. A control body for an aerosol delivery device, the control body comprising:
a power source configured to provide an output voltage; an aerosol production component or terminals configured to connect the aerosol production component to the control body, the aerosol production component powerable to produce an aerosol from an aerosol precursor composition; a sensor configured to produce measurements of atmospheric air pressure in an air flow path through the at least one housing; a switch coupled to and between the power source and the aerosol production component; and processing circuitry coupled to the sensor and the switch, and configured to at least:
