    Abstract: A liquid reservoir component of an electronic vaping device includes an outer casing extending in a longitudinal direction, an air inlet, and a vapor outlet. An inner tube is within the outer casing defining a central air passage communicates with the inlet and the outlet. A liquid reservoir is in an annular space between the outer casing and the inner tube. A susceptor is adjacent the central air passage, and a wick is in communication with the liquid reservoir and in thermal communication with the susceptor such that the susceptor is operable to heat the liquid material to a temperature to vaporize the liquid material and form a vapor in the central air passage. The liquid reservoir component is configured to connect with a power supply component such that an induction source is operable to generate an inductive field to heat the susceptor when powered by the power source.

    Abstract: A cartridge for an e-vaping device includes a conductive element extending through an interior of a dispensing interface to which a heating element is coupled. The conductive element may have a greater temperature coefficient of electrical resistivity than the heating element. The dispensing interface may include a fibrous wicking material, and the conductive element may be woven through an interior of the fibrous wicking material. A temperature of the dispensing interface may be determined based on monitoring an electrical resistance of the conductive element. An amount of pre-vapor formulation may be determined based on an electrical resistance of the bridge electrical circuit to an electrical signal between the heating element and the conductive element through the dispensing interface.

    Abstract: An exemplary smoking topography circuit of an electronic aerosol smoking article, includes at least one sensor configured to measure user interaction with the smoking article, a processor, and memory. The processor is configured to detect a smoking event based an output of the at least one sensor, collect data associated with the smoking event, and arrange the data in a pattern that associates the smoking event to shifts in battery voltage. The memory is configured to store the data pattern in a structured multi-byte format.

    Abstract: The method of making the e-vaping cartridge includes cutting at least one first hole through a first channel, sliding a housing over the first channel, the at least one first hole providing fluid communication between a first reservoir and a second reservoir, the first reservoir being defined between the housing and the first channel, where the second reservoir is defined between the first channel and a central passage traversing through the first channel. The method further includes inserting at least one first layer of absorbent material within the second reservoir, and positioning a heater and a wick in communication with the central passage. Distal ends of the wick contact the at least one first layer of absorbent material, where the heater is configured to vaporize a pre-vapor formulation that is communicated by the wick from the at least one first layer of absorbent material.

    Abstract: A cartridge for an e-vaping device includes an infrared sensor configured to measure infrared radiation emitted by at least a portion of a heating element coupled to a dispensing interface in the cartridge. The field of view of the infrared sensor may encompass an entirety of the heating element. The infrared sensor may be an infrared light emitting diode. The e-vaping device may include control circuitry configured to determine the temperature of the heating element based on sensor data generated by the infrared sensor and control the electrical power supplied to the cartridge based on the temperature of the heating element. The control circuitry may control the electrical power to maintain the temperature of the heating element below a threshold temperature. The control circuitry may determine the heating element temperature based on accessing at least a portion of the sensor data stored at a storage device in the cartridge.
