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 vapor generator assembly for an e-vaping device may include a reservoir configured to hold a pre-vapor formulation, a vaporizer assembly configured to heat pre-vapor formulation drawn from the reservoir to form a vapor, and an air intake assembly configured to direct ambient air into the vaporizer assembly. The air intake assembly may at least partially define an air inlet that extends at least partially around an outer surface of the vapor generator assembly. The air inlet may be an arcuate air inlet or an annular air inlet. The air intake assembly may at least partially define an inlet channel extending from the air inlet into an interior of the vapor generator assembly to at least partially establish fluid communication between the arcuate air inlet and the vaporizer assembly. The inlet channel may extend coaxially in relation to a longitudinal axis of the vapor generator assembly.

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 method of controlling a hot wire anemometer (HWA) of a nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

Abstract: A method of controlling a hot wire anemometer (HWA) of a non-nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the non-nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the non-nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the non-nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

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: The e-vaping device includes a vaporizer assembly, which includes a heating element, a pre-vapor formulation reservoir, a pre-vapor formulation level indicator including a plurality of discrete indicator segments, and at least one processor. The pre-vapor formulation reservoir may be configured to contain a pre-vapor formulation and the at least one processor may be configured to determine a difference between a first duty cycle of power supplied to the heating element and a second duty cycle of power supplied to the heating element; and adjust the indicator based on the determined duty cycle difference.

Abstract: A nicotine pod assembly for a nicotine e-vaping device may include a pod body and a connector module. The pod body has an upstream end and a downstream end and is configured to hold a nicotine pre-vapor formulation. The upstream end of the pod body defines a cavity. The connector module is configured to be seated within the cavity of the pod body. The connector module may include an external face and a side face. The external face of the connector module includes at least one electrical contact and defines a pod inlet. The side face of the connector module defines at least one module inlet. The side face of the connector module faces a sidewall of the cavity in the pod body when the connector module is seated within the cavity.
