    摘要: 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.

    摘要: An apparatus and method of controlling resistance-to-draw of an electronic smoking article is disclosed, which includes a reusable portion and a cartomizer portion, and which includes: supplying an air flow from one or more inlets in an outer cylindrical housing of the electronic smoking article to a cartomizer via a cartomizer inlet having a fixed diameter configured to control a resistance-to-draw of the electronic smoking article and wherein the cartomizer inlet is located inside the outer cylindrical housing of the electronic smoking article, wherein a combined air flow area of the one or more inlets in the outer housing of the electronic smoking article are greater than a cross-sectional area of the cartomizer inlet; heating a liquid material from a reservoir to form an aerosol; and combining the at least initially volatilized liquid material with the air flow from the cartomizer inlet.
