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: 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.

Abstract: The heating engine control circuit includes a rail converter circuit and a gate driver circuit. The rail converter circuit is configured to convert a power supply voltage into a power signal based on a vaping enable signal, the vaping enable signal being a pulse width modulated signal. The gate driver circuit includes an integrated gate driver. The integrated gate driver is configured to control application of power to a heater of the non-nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

Abstract: A device assembly includes a controller, which is configured to control the non-nicotine electronic vaping device to output an indication of a current level of the non-nicotine pre-vapor formulation in the non-nicotine reservoir of a non-nicotine pod assembly in response to determining that an aggregate amount of non-nicotine pre-vapor formulation drawn from the non-nicotine reservoir or an aggregate amount of vaporized non-nicotine pre-vapor formulation is greater than or equal to the at least one non-nicotine pre-vapor formulation level threshold.

Abstract: The non-nicotine electronic vaping device includes processing circuitry configured to: determine a plurality of resistance values for a heater during a time window; calculate a percent change in resistance of the heater between a first of the plurality of resistance values and a second of the plurality of resistance values; decide whether the percent change in resistance of the heater exceeds a percent change in resistance threshold; and disable power to the heater in response to deciding that the percent change in resistance of the heater exceeds the percent change in resistance threshold.

Abstract: A capsule for a heat-not-burn (HNB) aerosol-generating device may include a housing and a heater within the housing. The housing has interior surfaces defining a chamber configured to hold an aerosol-forming substrate. In addition, the housing has exterior surfaces constituting a first face, an opposing second face, and a side face of the capsule. The first face and the second face of the capsule are permeable to an aerosol. The heater has a first end section, an intermediate section, and a second end section. The first end section and the second end section of the heater may be external segments constituting parts of the side face of the capsule. The intermediate section of the heater is an internal segment disposed within the chamber of the housing.

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.
