Abstract: An aerosol-generating device is provided, including: a cavity configured to receive an aerosol-forming substrate; an electrical heater to heat the substrate when received within the cavity; a power supply; and a controller to control a supply of power to the heater during a first time period and a subsequent second time period, determine an initial temperature of the heater, and to determine a rate of increase in temperature of the heater during the first time period by determining a time taken for a temperature of the heater to increase from a first to a second predetermined temperature during the first time period, and adjust the supply of power to the heater during the second time period based on the initial temperature of the heater and based on the determined rate of increase in temperature of the heater during the first time period.

Abstract: An aerosol-generating device is provided, including: a cavity to receive an aerosol-forming substrate; an electrical heater to heat the substrate when received within the cavity; a rechargeable power supply to provide first and second experiences without intermediate recharge; and a controller to control power to the heater during first and second time periods, determine in the first time period whether the experience is the first or the second experience, and to determine a rate of increase in a heater temperature during the first time period by determining a time taken for the heater temperature to increase from a first to a second predetermined temperature during the first time period, and adjust the power during the second time period based on if the experience is the first or the second experience and based on the determined rate of increase in the heater temperature during the first time period.

Abstract: A smoking article is provided, including a combustible heat source having opposed front and rear faces; an aerosol-forming substrate downstream of the rear face; a first heat-conducting element circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate; a second heat-conducting element around at least a portion of the first heat-conducting element, wherein at least part of the second heat-conducting element is radially separated from the first heat-conducting element; and one or more first air inlets around a periphery of the aerosol-forming substrate.
