Abstract: A cartomizer for an electronic smoking article, an electronic smoking article capable of providing a smoking experience without combusting tobacco, and a method of achieving a smoking experience without combusting tobacco are disclosed. The cartomizer can include an annular fluid reservoir having an air flow channel therein; a liquid material within the fluid reservoir; and a heater, which surrounds the fluid reservoir and is operable to heat the fluid reservoir to a temperature sufficient to at least initially volatilize the liquid material contained within the fluid reservoir to form a saturated vapor within the air flow channel.

Abstract: An electronic smoking article or electronic vaping article includes a reservoir containing a liquid material and having an outlet, a capillary having a capillary inlet and a capillary outlet, the capillary inlet of the capillary in communication with the outlet of the reservoir, a heater operable to heat the capillary to a temperature sufficient to at least initially volatilize liquid material contained within the capillary, and a shuttle valve between the outlet of the reservoir and the capillary inlet. The shuttle valve is operable to prevent release of liquid material from the reservoir when the shuttle valve is in a closed position and is operable to release liquid material from the reservoir when the shuttle valve is in an open position.

Abstract: An electronic smoking article includes a liquid supply region including liquid material and a heater-wick element operable to wick liquid material and heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol. The heater-wick element is formed of a carbon or graphite foam.

Abstract: An electronic smoking article includes a heater in communication with a liquid supply reservoir including liquid material and operable to heat the liquid material to a temperature sufficient to volatilize the liquid material contained therein and form an aerosol. The volatilized material flows through a sheath flow and aerosol promoter insert that is operable to cool the aerosol, reduce the particle size of the aerosol and increase the delivery rate of the aerosol.

Abstract: A sensor apparatus may include a channel structure configured to couple with an external element and a fluid conduit, such that the channel structure may receive a fluid, at least partially drawn through the external element from an ambient environment, and direct the fluid through the fluid conduit. A sensor may generate sensor data indicating a flow rate of the fluid through the fluid conduit based on monitoring a variation in a pressure at a location in hydrodynamic contact with the fluid conduit and in relation to an ambient pressure of the ambient environment. The sensor apparatus may enable generation of improved topography information associated with flows of fluid drawn from the external element based on measuring a local pressure at the location in hydrodynamic contact with the fluid conduit and determining the ambient pressure based on monitoring the local pressure over time.

Abstract: A sensor apparatus may include a conduit structure including an inner surface defining a conduit extending through an interior of the conduit structure, an inlet structure coupled to an end of the conduit structure, and a plurality of sensor devices in hydrodynamic contact with the conduit. The inlet structure may couple with an outlet end of an external tobacco element to hold the outlet end of the external tobacco element in fluid communication with an inlet opening of the conduit structure, such that the conduit structure may receive a generated aerosol from the external tobacco element at the inlet opening, and draw an instance of aerosol through the conduit towards an outlet opening. The instance of aerosol may include at least a portion of the generated aerosol. Each sensor device may generate sensor data indicating a pressure of the instance of aerosol through a separate portion of the conduit.
