    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 e-vaping cartridge includes a housing, a first tube extending in a longitudinal direction within the housing, the first tube defining at least one first hole that provides fluid communication between a first annulus reservoir and a second annulus reservoir, the first annulus reservoir defined between the housing and the first tube, the second annulus reservoir defined between the first tube and a central passage traversing through the first tube. At least one first layer of absorbent material is positioned within the second annulus reservoir. A wick is in communication with the central passage, where distal ends of the wick contact the at least one first layer of absorbent material. A 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. The device includes the cartridge.

    Abstract: An electronic smoking article is disclosed, which includes an outer housing extending in a longitudinal direction; a micro pump system configured to pump a liquid material contained within a liquid supply reservoir through an outlet of the supply reservoir into a capillary; the capillary having an inlet and an outlet, the inlet in communication with the outlet of the liquid supply reservoir; a heating arrangement operable to heat the capillary to a temperature sufficient to at least initially volatilize the liquid material contained within the capillary; a power supply operable to apply voltage to the micro pump gas cell to generate a gas to drive the liquid material out of the liquid supply reservoir into the inlet of the capillary; at least one air inlet; and whereby air is mixed with the volatilized material to form an aerosol.

    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.

    Abstract: An e-vaping device includes a first section capable of containing a liquid material. The first section includes a heater capable of vaporizing the liquid material, and a wick capable of drawing the liquid material to the heater. A male threaded connection with non-standard male threads is on one end of the first section. The e-vaping device also includes a second section with a power supply. The second section includes a female threaded connection on one end, where the female threaded connection includes female threads that mate with the non-standard male threads of the first section.
