Abstract: A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first frame, a second frame, a first heater, a second heater, and/or an aerosol-forming substrate. The first frame has a first interior face and a first exterior face. In addition, the first frame defines a first opening. The first heater may be secured to the first frame so as to cover the first opening. The second frame is connected to the first frame. The second frame has a second interior face and a second exterior face. Furthermore, the second frame defines a second opening. The second heater may be secured to the second frame so as to cover the second opening. The aerosol-forming substrate may be between the first heater and the second heater.

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.
