    Abstract: The e-vaping device includes a housing, the housing defining one or more inlets, a power source, and a cartridge. The cartridge includes a reservoir containing a pre-vapor formulation. A heater and wick arrangement is in fluid communication with the reservoir. An annular seal is in fluid communication with the one or more inlets. The annular seal defines a first air passage. A flow restrictor is held by the annular seal. The flow restrictor defines a second air passage, the second air passage being configured to provide a desired resistance-to-draw (RTD) for the e-vaping device. A combined airflow cross-sectional area of the one or more inlets is greater than an airflow cross-sectional area of the second air passage. The flow restrictor is made from a first material that is harder than a second material for the annular seal.

    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.
