Abstract: A capsule for a heat-not-burn (HNB) aerosol-generating device may include a base portion, a first cover, a second cover, an aerosol-forming substrate, and a heater. The base portion includes an engagement assembly configured to couple with the first cover and the second cover. The first cover defines a first recess, and the second cover defines a second recess. When assembled, the first cover is aligned with the second cover such that the first recess and the second recess collectively form a chamber. The aerosol-forming substrate is within the chamber. The heater is configured to heat the aerosol-forming substrate to generate an aerosol. The heater includes a first end section, an intermediate section, and a second end section. The heater extends through the base portion such that the intermediate section is in the chamber, while the first end section and the second end section are external segments.

Abstract: At least one example embodiment provides s system for controlling a heater in a non-combustible aerosol-generating device. The system comprises a memory storing computer-readable instructions and a controller configured to execute the computer-readable instructions to cause the non-combustible aerosol-generating device to, detect an airflow in the non-combustible aerosol-generating device, apply a first power to the heater based on the detected airflow, apply a second power to the heater based on a target preheat temperature and the detected airflow being below an airflow threshold value, the application of the second power being after the application of the first power, and apply a third power to the heater based on the target preheat temperature and the detected airflow being below the airflow threshold value, the application of the third power being after the application of the second power, the third power being greater than the second power.

Abstract: A heater system for a non-combustible aerosol-generating device includes a heater element and a fuse element. The heater element has a heating region, a first terminal and a second terminal. The fuse element is electrically connected between the first terminal and the second terminal in parallel with the heater element. The fuse element has a region configured to induce a localized hot spot to cause the fuse element to open circuit in response to power applied between the first terminal and the second terminal.

Abstract: A capsule may include a housing, an aerosol-forming substrate, and a heater. The housing defines inlet openings, outlet openings, and a chamber between the inlet openings and the outlet openings. The chamber may have a longest dimension extending from at least one of the inlet openings to a corresponding one of the outlet openings. The aerosol-forming substrate is within the chamber of the housing. The heater is embedded in the housing. The heater includes a first end section, an intermediate section, and a second end section. The intermediate section is disposed within the aerosol-forming substrate in the chamber. An aerosol-generating device may include a device body with a lid configured to open to permit an insertion of the capsule and configured to close to engage the capsule within the device body.

Abstract: An aerosol-generating device includes a sensor configured to detect puffs; and processing circuitry configured to cause the aerosol-generating device to increase a temperature of a heater to a preheat temperature, decrease the temperature of the heater to a first heating temperature before a first detected puff of the detected puffs, the first heating temperature being below the preheat temperature, and increase the temperature of the heater based on a number of the detected puffs.

Abstract: A cooldown system for a device includes at least one processor and a memory coupled to the at least one processor. The memory is configured to store instructions. The at least one processor is configured to execute the instructions to cause the cooldown system to detect when a session has ended, activate a cooldown timer to measure a cooldown time, provide an indication of a remaining time of the cooldown timer, and in response to the cooldown timer elapsing, return the device to normal operation.

Abstract: A capsule for an aerosol-generating device may include a housing, a filter, and an aerosol-forming substrate. The housing may have a gas-permeable end and an impermeable end. The filter may be disposed within the housing so as to be adjacent to the impermeable end. The aerosol-forming substrate may be disposed within the housing so as to be between the filter and the gas-permeable end. The housing may be configured to facilitate a heating of the aerosol-forming substrate via one of conduction, convection, or both conduction and convection so as to generate an aerosol.
