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.

An e-vaping case includes a housing, a guide structure, a cartridge receiving portion connected to the guide structure, and an electronics system in the housing. The cartridge receiving portion is configured to be moved along the guide structure between a first surface and a second surface of the housing. The electronics system includes a power supply that is configured to initiate a transfer of power to an electrical contact structure if the cartridge receiving portion is moved towards the first surface of the housing to at least a first position of the housing. The electronics system is configured to interrupt the transfer of power to the electrical contact structure if the cartridge receiving portion is moved towards the second surface of the housing. An electronic vaping device may include a cartridge detachably coupled to the cartridge receiving portion.

E-vaping device including e-vaping case with sliding mechanism for initiating vapor generation

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 to heat nicotine pre-vapor formulation drawn from a nicotine reservoir at the nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

Aerosol-generating capsule

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.

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.

Non-nicotine electronic vaping devices having non-nicotine pre-vapor formulation level detection and auto shutdown

An embodiment of an electronic vaping device includes: a memory; a light emitting device configured to optically transmit information associated with the electronic vaping device to an external device; and processing circuitry coupled to the memory and the light emitting device. The processing circuitry may be configured to: collect the information associated with the electronic vaping device; store the information in the memory; detect a triggering event; and initiate optical transmission of the information by the light emitting device in response to detecting the triggering event.

Methods and devices for communication of data between electronic vaping device and external device

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