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.

Abstract: In some example embodiments, a reservoir assembly may include a reservoir and an isolation structure. The reservoir may hold a pre-vapor formulation. The reservoir may include a first fluid port extending through a housing of the reservoir, where the first fluid port may enable fluid communication between the reservoir and an exterior of the reservoir assembly. The reservoir may be coupled to a vaporizer assembly that includes a second fluid port configured to enable fluid communication between the reservoir and vaporizer assembly, or the reservoir may be coupled to a vaporizer connector assembly that includes a second fluid port configured to enable fluid communication between the reservoir and an exterior through the vaporizer connector assembly. The isolation structure may move in relation to the reservoir and the vaporizer connector assembly to a position where it exposes one of the fluid ports and covers the other.

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 nicotine e-vaping device includes a heater, a power control circuit, and a memory module. The heater element is configured to heat nicotine pre-vapor formulation. The power control circuit is coupled to the heater element through a wire. The power control circuit is configured to apply a pulse width modulated power signal to the heater element through the wire, and to receive information over the wire. The memory module is configured to detect a plurality of pulses in the pulse width modulated power signal, record information based on the detected plurality of pulses, and output the recorded information to the power control circuit via the wire.

Abstract: Some example embodiments include a reservoir assembly for an e-vaping device that may include a reservoir, a first bayonet connector assembly, and a conduit extending from a vaporizer assembly and into a space defined by the first bayonet connector assembly. The first bayonet connector assembly may detachably couple with a second bayonet connector assembly of an outlet assembly to establish a bayonet interface connection between the reservoir and the outlet assembly, such that the conduit is in fluid communication with the exterior of the reservoir assembly through an interior of the outlet assembly.

Abstract: An e-vapor apparatus may include a pod assembly and a dispensing body configured to receive the pod assembly. A vaporizer may be disposed in the pod assembly and/or the dispensing body. The pod assembly may include a vapor precursor compartment, a device compartment, and a vapor channel extending from the device compartment and traversing the vapor precursor compartment. The pod assembly is a smart pod configured to receive, store, and transmit information that can be communicated with the dispensing body and/or another electronic device. The proximal portion of the dispensing body includes a vapor passage and a through-hole. The vapor passage may extend from an end surface of the proximal portion to a side wall of the through-hole. The through-hole is configured to receive the pod assembly such that the vapor channel of the pod assembly is aligned with the vapor passage of the dispensing body.

Abstract: The cartridge includes a housing, a reservoir containing a pre-vapor formulation, a vapor generator in communication with a central passage, the central passage including a first portion, a second portion and a third portion. The vapor generator is configured to communicate the pre-vapor formulation to the first portion of the central passage. A first air inlet is in communication with the second portion of the central air passage, where the second portion is between the vapor generator and the first air inlet. A dilution air inlet intersects the third portion of the central air passage, where the third portion is between the vapor generator and an outlet of the cartridge. The dilution air inlet defines a dilution air passage that does not pass through the vapor generator. The e-vaping device includes the cartridge.
