Abstract

A method of controlling a heater of a device including a removable container that stores a material includes detecting, from the removable container, power information indicating a first operating point and a second operating point; and supplying power to the heater based on the detected power information by, determining a first amount of power based on the first operating point, supplying the first amount of power to the heater during a first operation mode of the heater, determining a second amount of power based on the second operating point, and supplying the second amount of power to the heater during a second operation mode of the heater, the second amount of power being higher than the first amount of power, the device being a non-nicotine e-vaping device or a heat-not-burn aerosol-generating device, the material being a non-nicotine pre-vapor formulation or an aerosol-forming substrate.

receiving, via one or more touch sensors located on the non-nicotine e-vaping device, a selection of a coarse preference level from among the plurality of coarse preference levels;

selecting an operating point from among the plurality of operating points that corresponds to the selected coarse preference level as the second operating point; and

supplying power to the heater based on the detected power information by,

determining a first amount of power based on the first operating point,

supplying the first amount of power to the heater during a first operation mode of the heater,

determining a second amount of power based on the second operating point, and

supplying the second amount of power to the heater during a second operation mode of the heater,

the second amount of power being higher than the first amount of power.

2. The method of claim 1 , wherein,

the first amount of power supplied during the first operation mode is an amount that causes the heater to heat the non-nicotine pre-vapor formulation stored in the non-nicotine e-vaping device to a temperature below a boiling point of the non-nicotine pre-vapor formulation, and

the second amount of power supplied during the second operation mode is an amount that causes the heater to heat the non-nicotine pre-vapor formulation stored in the non-nicotine e-vaping device to a temperature equal to, or greater than, the boiling point of the non-nicotine pre-vapor formulation.

3. The method of claim 2 , wherein the non-nicotine pre-vapor formulation is stored in the removable container.

4. The method of claim 2 , wherein the removable container includes the heater.

5. The method of claim 1 , wherein the determining of the second amount of power comprises:

receiving, by the non-nicotine e-vaping device from an external source, a selection of a fine preference level, from among a plurality of fine preference levels; and

determining the second amount of power based on the second operating point and the selected fine preference level.

6. The method of claim 5 , wherein the external source is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the non-nicotine e-vaping device, the selection of the fine preference level via a wireless communication link between the non-nicotine e-vaping device and the external source.

7. The method of claim 1 , wherein the plurality of operating points includes a first plurality of operating points, and

the method further comprises:

receiving, via the one or more touch sensors located on the non-nicotine e-vaping device, a selection of a second coarse preference level, from among the plurality of coarse preference levels; and

selecting an operating point, from among the first plurality of operating points, that corresponds to the selected second coarse preference level as the first operating point.

8. The method of claim 7 , wherein the determining of the first amount of power comprises:

receiving, by the non-nicotine e-vaping device from an external source, a selection of a fine preference level from among a plurality of fine preference levels; and

determining the first amount of power based on the first operating point and the selected fine preference level.

9. The method of claim 8 , wherein the external source is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the non-nicotine e-vaping device, the selection of the fine preference level via a wireless communication link between the non-nicotine e-vaping device and the external source.

10. The method of claim 8 , wherein

the plurality of operating points further includes a second plurality of operating points, and

the selecting the operating point from among the plurality of operating points includes selecting the operating point from the second plurality of operating points.

11. The method of claim 10 , wherein the determining of the second amount of power comprises:

determining the second amount of power based on the second operating point and the selected fine preference level.

12. The method of claim 11 , wherein the external source is a wireless communication device, and the receiving of the selection of the fine preference level comprises:

receiving, by the non-nicotine e-vaping device, the selection of the fine preference level via a wireless communication link between the non-nicotine e-vaping device and the external source.

13. The method of claim 1 , wherein the detecting of the power information comprises:

reading, by the non-nicotine e-vaping device, the power information from an image located on the removable container.

14. The method of claim 13 , wherein the image includes a QR code, and the reading of the power information comprises:

reading, by the non-nicotine e-vaping device, the power information from the QR code located on the removable container.

15. The method of claim 1 , wherein,

the detecting of the power information comprises:

reading, by the device, the power information from a memory of the removable container.

16. A method of controlling a heater of a heat-not-burn aerosol-generating device, the heat-not-burn aerosol-generating device including a removable container that stores an aerosol-forming substrate, the method comprising:

detecting, from the removable container, power information indicating a first operating point and a second operating point, the power information including a plurality of operating points that correspond, respectively, to a plurality of coarse preference levels, the plurality of operating points including the first operating point and the second operating point;

receiving, via one or more touch sensors located on the heat-not-burn aerosol-generating device, a selection of a coarse preference level from among the plurality of coarse preference levels;

selecting an operating point from among the plurality of operating points that corresponds to the selected coarse preference level as the second operating point; and
