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: 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.

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 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.
