     DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS 
     Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely provided for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only some example embodiments set forth herein. 
     Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiments. Like numbers refer to like elements throughout the description of the figures. 
     It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments. 
     Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     When the terms “about” or “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value include a tolerance of ±10% around the stated numerical value. The expression “up to” includes amounts of zero to the expressed upper limit and all values therebetween. When ranges are specified, the range includes all values therebetween such as increments of 0.1%. Moreover, when the words “generally” and “substantially” are used in connection with geometric shapes or other descriptions, it is intended that precision of the geometric shape or description is not required but that latitude for the shape or description is within the scope of the disclosure. Although the tubular elements of the embodiments may be cylindrical, other tubular cross-sectional forms are contemplated, such as square, rectangular, oval, triangular and others. 
     The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, etc., but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, etc., and/or groups thereof. 
     Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
       FIG.  1 A  is a side view of an assembly that includes a sensor apparatus and external tobacco element according to some example embodiments.  FIG.  1 B  is a cross-sectional side view of a region A of the assembly of  FIG.  1 A  according to some example embodiments.

An inner surface  111  of the housing  110  may define an internal space  112  in which various elements of the sensor apparatus  100  are located. In some example embodiments, including the example embodiments shown in  FIGS.  1 A- 1 B , the housing  110  may be a multi-piece assembly of two or more housing pieces that are coupled together via coupling of connector elements  194  to form the housing  110 . As shown in  FIG.  1 A , the connector elements  194  may be screw connectors, but in some example embodiments the connector elements  194  may be any connector elements that may couple two or more separate pieces of a housing together to form a housing  110 . In some example embodiments, the housing  110  may be a unitary piece of material, such that connector elements  194  may be absent from the assembly  300 . 
     In some example embodiments, including the example embodiments shown in  FIG.  1 B , the conduit structure  120  may be a cylindrical structure having an outer surface  121 , an inner surface  123 , an inlet opening  125 , and an outlet opening  127 . The inner surface  123  may define a conduit  129  extending between the inlet opening  125  and the outlet opening  127 . In some example embodiments, including the example embodiments shown in  FIG.  1 B , the conduit  129  may be partitioned by an orifice structure  280  into separate conduit portions  129 A,  129 B that are at least partially defined by one or more elements of the conduit structure  120 . 
     In some example embodiments, including the example embodiments shown in  FIG.  1 B , the conduit structure  120  may extend through the internal space  112  of the housing  110  between opposing housing openings  114 ,  116  at opposite ends  183 A,  183 B of the housing  110 . In some example embodiments, including the example embodiments shown in  FIG.  1 B , the internal space  112  may be an annular space that is defined between an inner surface  111  of the housing  110  and an outer surface  121  of the conduit structure  120 . However, it will be understood that, in some example embodiments, the internal space  112  that is defined by the inner surface  111  of the housing  110  may be non-annular. 
     The inlet structure  130  includes a housing  131 , having an inner surface  133  and an outer surface  135 , that defines an inlet conduit  137  extending through an interior of the inlet structure  130  between an inlet opening  136  and an outlet opening  138  thereof. In some example embodiments, including the example embodiments shown in  FIG.  1 B , the inlet structure  130  may include a first portion  132  and a second portion  134 . As shown in  FIG.  1 B , the first portion  132  may be configured to connect with an outlet end  201  of an external tobacco element  200  via inlet opening  136 , such that aerosol may be drawn from the external tobacco element  200  into the inlet conduit  137 . As further shown in  FIG.  1 B , the second portion  134  may be configured to connect with the conduit structure  120 . In some example embodiments, including the example embodiments shown in  FIG.  1 B , the first and second portions  132 ,  134  of the inlet structure  130  may have different diameters, where the first portion  132  has a diameter that corresponds to a diameter of the external tobacco element  200  and the second portion  134  has a diameter that corresponds to a diameter of the conduit structure  120 , and where the diameter of the first portion  132  may be greater than the diameter of the second portion  134 . However, it will be understood that example embodiments are not limited thereto. For example, the first portion  132  and the second portion  134  may have a similar or same diameter. In another example, the diameter of the first portion  132  may be less than the diameter of the second portion  134 . 
     In some example embodiments, including the example embodiments shown in  FIG.  1 B , the second portion  134  may be configured to extend around an outer surface  121  of the conduit structure  120 , but example embodiments are not limited thereto. For example, the second portion  134  may extend into the conduit  129  such that the inner surface  123  of the conduit structure  120  extends around the second portion  134 . In some example embodiments, inlet conduit  137  is in fluid communication with conduit  129 , and aerosol that is drawn into the inlet conduit  137  from the external tobacco element  200  may be further drawn into the conduit  129  from the inlet conduit  137 . In some example embodiments, the inlet structure  130  may be configured to establish a generally airtight seal between the outlet end  201  of the external tobacco element  200  and the conduit structure  120 . Aerosol drawn into the inlet conduit  137  from the external tobacco element  200  may be further drawn into the conduit  129  of the conduit structure  120 . 
     In some example embodiments, including the example embodiments shown in  FIG.  1 B , the inlet structure  130  housing  131  may comprise a flexible material that has a first portion  132  that flares in diameter towards the inlet opening  136  and is configured to flex to accommodate and establish a generally airtight seal, via friction fit, with various external tobacco elements  200  that may have different sizes. Accordingly, the versatility of the sensor apparatus  100  to couple with external tobacco elements  200  having different sizes and/or diameters may be improved, thereby improving the utility of the sensor apparatus  100 . 
     In some example embodiments, including the example embodiments shown in  FIGS.  1 A- 1 B , the inlet structure  130  is configured to be detachably connected to the external tobacco element  200 , such that the external tobacco element  200  may be detached from the sensor apparatus  100  and/or may be swapped for another, separate external tobacco element  200  in assembly  300 . But, example embodiments are not limited thereto. For example, in some example embodiments, the external tobacco element  200  may be fixed to the inlet structure  130 , for example via an adhesive binding the inner surface  133  of the inlet structure  130  to an outer surface of the external tobacco element  200 . 
     In some example embodiments, the conduit structure  120  may be connected to the inlet structure  130  via engagement of plug connector elements  196 A that extend from an inner surface  133  of the inlet structure  130  with complementary receptacle connector elements  197 A that extend around an outer surface  121  of the conduit structure  120 , in order to more firmly connect the inlet structure  130  and the conduit structure  120  together. It will be understood that in some example embodiments the plug connector elements  196 A may protrude from the outer surface  121  of the conduit structure  120  and may engage with complementary receptacle connector elements  197 A that extend around an inner surface  133  of the inlet structure  130 . 
     It will be understood that, in some example embodiments, the plug connector elements  196 A and/or the receptacle connector elements  197 A may be absent from the sensor apparatus  100 , such that the conduit structure  120  may be connected to the inlet structure  130  via friction fit between the conduit structure  120  and the inlet structure  130 , adhesive bonding between the conduit structure  120  and the inlet structure  130 , engagement of one or more different connector elements between the inlet structure  130  and the conduit structure  120 , some combination thereof, or the like. 
     The outlet structure  140  may include an outlet structure housing  141  having an inner surface  142  that defines an outlet conduit  149  extending through an interior of the outlet structure  140  between an inlet opening  146  and an opposite outlet opening  148 .

     It will be understood that, in some example embodiments, the plug connector elements  196 B and/or the receptacle connector elements  197 B may be absent from the sensor apparatus  100 , such that the conduit structure  120  may be connected to the outlet structure  140  via friction fit between the conduit structure  120  and the outlet structure  140 , adhesive bonding between the conduit structure  120  and the outlet structure  140 , engagement of one or more different connector elements between the outlet structure  140  and the conduit structure  120 , some combination thereof, or the like. 
     In some example embodiments, including the example embodiments shown in  FIGS.  1 A- 1 B , the inlet structure  130  and the outlet structure  140  may each be configured to be detachably connected to the conduit structure  120 , but example embodiments are not limited thereto. For example, the inlet structure  130  may be fixed to the conduit structure  120  via an adhesive material. In another example, the outlet structure  140  may be fixed to the conduit structure  120  via an adhesive material. 
     In some example embodiments, the conduit structure  120 , the inlet structure  130 , the outlet structure  140 , a sub-combination thereof, or a combination thereof may form part of a unitary piece of material, instead of an assembly of two or more coupled elements as shown in at least  FIG.  1 B . 
     As shown in  FIG.  1 B , in some example embodiments, the sensor apparatus  100  may include pressure sensor devices  172 A,  172 B, control circuitry  171 , interface device  184 , temperature sensor device  179 , a power supply  180 , and a feedback device  199 .

The interface device  184  may be coupled to the port  186 , and port  186  may expose the interface device  184 , such that the interface device  184  may be accessible, from an exterior of the housing  110 , through port  186 . In addition, the outlet structure  140  may be configured to be detachable from the conduit structure  120  to expose the port  186 , and thus the interface device  184 , to an exterior of the housing  110 . For example, in some example embodiments, the interface device  184  may be a Universal Serial Bus (USB) connector interface that is accessible via port  186  and may be reversibly covered or exposed by the detachable outlet structure  140  detachably connecting with the conduit structure  120 .

In some example embodiments, the interface device  184  is a power supply interface that is configured to couple with an external power source to enable the power supply  180  to be charged or recharged with stored electrical power. In some example embodiments, the interface device  184  may include both a communication interface and a power supply interface. 
     In some example embodiments, the port  186  may extend through a portion of the housing  110  that is not configured to be covered by the outlet structure  140 , such that the port  186  may be exposed even when the outlet structure  140  is connected. 
     In some example embodiments, the port  186  may be absent from sensor apparatus  100 , and the interface device  184  may be a wireless network communication interface that is configured to establish a wireless network communication link with one or more external devices. In some example embodiments, the sensor apparatus  100  may include a power interface and a separate communication interface, where the power interface is configured to be electrically coupled to an external power supply to enable power to be supplied to the power supply  180 , and where the communication interface, which may be a wired communication interface and/or a wireless communication interface, may be configured to establish a communication link with an external device. 
     In some example embodiments, including the example embodiments shown in  FIG.  1 B , the pressure sensor devices  172 A,  172 B may be in hydrodynamic contact with separate, respective conduit portions  129 A,  129 B of the conduit  129 . Accordingly, the pressure sensor devices  172 A,  172 B may be configured to measure a local pressure of aerosol at a separate, respective conduit portion  129 A,  129 B of the conduit  129  and thus may each be configured to generate sensor data indicating a pressure of an instance of aerosol drawn through a separate, respective conduit portion  129 A,  129 B of the conduit  129 . It will be understood that, in some example embodiments, a pressure sensor device may be configured to generate sensor data that may be processed by a processor to enable the processor to determine a magnitude of the local aerosol pressure. In some example embodiments, each pressure sensor device  172 A,  172 B may be a microelectromechanical system (MEMS) sensor. 
     As shown in  FIG.  1 B , the conduit structure  120  may define conduits  188 A,  188 B that extend between separate conduit portions  129 A,  129 B of the conduit  129  and respective pressure sensor devices  172 A,  172 B, thereby establishing hydrodynamic contact between the pressure sensor devices  172 A,  172 B and respective conduit portions  129 A,  129 B. As shown in  FIG.  1 B , the pressure sensor devices  172 A,  172 B may be connected to the control circuitry  171 , and the conduit structure  120  may be coupled to the control circuitry  171  to enclose the pressure sensor devices  172 A,  172 B in separate, respective conduits  188 A,  188 B. As further shown in  FIG.  1 B , one or more gasket structures  193 , which may include adhesive material, may establish a seal between the conduit structure  120  and the control circuitry  171  to enclose the pressure sensor devices  172 A,  172 B within the conduits  188 A,  188 B. 
     It will be understood that, in some example embodiments, the conduits  188 A,  188 B may be established by multiple structures that are coupled to the conduit structure  120  to enclose the pressure sensor devices  172 A,  172 B. 
     In some example embodiments, the temperature sensor device  179  that is configured to measure a temperature at conduit portion  129 A. It will be understood, however, that in some example embodiments the temperature sensor devices  179  may measure a temperature at conduit portion  129 B and/or conduit portion  129 A. The temperature sensor devices  179  may be coupled to control circuitry  171  and may be in thermal communication with the conduit  129  via conduit  195 , where the conduit  195  may be defined by conduit structure  120 . Accordingly, the temperature sensor device  179  may be configured to measure a temperature of aerosol in the conduit  129 . 
     In some example embodiments, the sensor data generated by the temperature sensor device  179  may be processed to determine whether the external tobacco element  200  is depleted below a threshold level. As an external tobacco element  200  of some example embodiments combusts tobacco material included therein, the external tobacco element  200  may be progressively depleted. As the external tobacco element is progressively depleted, a temperature of the generated aerosol  220  that is drawn into the sensor apparatus  100  may increase or decrease. Accordingly, the sensor data generated by the temperature sensor device  179  may be processed to determine a temperature of the aerosol  240 , and the temperature may be compared with a threshold temperature that is associated with depletion of the external tobacco element  200 . The threshold temperature value may be stored in a memory, which may be included in the sensor apparatus  100  and/or an external device. Based on a determination that the determined temperature of the aerosol  240  is past the threshold temperature (e.g., greater than or less than the threshold temperature), a determination may be made that the external tobacco element  200  is depleted, and an indication of said depletion may be provided via one or more interface devices, including a light indicator, a display screen, or the like. 
     The sensor apparatus  100  may include an initialization interface  182  that is configured to selectively initialize the sensor apparatus  100  based on adult tobacco consumer (“ATC”) interaction with the initialization interface  182 . 
     Still referring to  FIG.  1 B , the conduit structure  120  may include an orifice structure  280  within the conduit  129 . The orifice structure  280  may include an orifice  282  having a reduced diameter relative to the diameter of the conduit  129 , such that the conduit structure  120  is configured to direct aerosol drawn through the conduit  129  from the external tobacco element  200  to pass through the orifice  282  towards the outlet opening  148  of the outlet structure  140 . The orifice structure  280  may include any flow orifice or fluid orifice structure that is known in the relevant art, including an orifice plate, a Venturi Nozzle, some combination thereof, or the like. In some example embodiments, the orifice structure  280  may include multiple orifices  282 . 
     Still referring to  FIGS.  1 A- 1 B , in some example embodiments, the sensor apparatus  100  may couple with external tobacco element  200  to form an assembly  300 . The external tobacco element  200  may include one or more inlets  44  at an inlet end  202  of the external tobacco element  200  and one or more outlets  22  at an outlet end  201  of the external tobacco element  200 . The external tobacco element  200  may include a cigarette, a cigar, a cigarillo, or the like. In some example embodiments, the external tobacco element  200  may be configured to enable ambient air  210  to be drawn into the external tobacco element  200  from an ambient environment  310  via the one or more inlets  44 . Generated aerosol  220  may be generated in the interior of the external tobacco element  200 , for example based on combustion of a tobacco material in the presence of the ambient air  210 , non-combustion heating of a tobacco material in the presence of the ambient air  210 , or a combination thereof. In some example embodiments, the generated aerosol  220  may be referred to as smoke. The generated aerosol  220  may be drawn through the one or more outlets  22  and thus out of the external tobacco element  200 . As described herein, an aerosol may include a mixture of the generated aerosol  220  and one or more other gases, including ambient air  210 . 
     As shown in  FIG.  1 B , in some example embodiments, the generated aerosol  220  may be drawn through the one or more outlets  22  and into the conduit  129  of the conduit structure  120 , via inlet conduit  137 . The aerosol drawn through at least a portion of conduit  129  and further through the outlet opening  148 , which may partially or entirely comprise the generated aerosol  220 , is referred to herein as a drawn aerosol  230 . 
     Still referring to  FIG.  1 B , in some example embodiments, the generated aerosol  220  that is drawn from the external tobacco element  200  and into the conduit  129  at the inlet opening  125  of the conduit  129  may be drawn through the first conduit portion  129 A of the conduit  129  as aerosol  240 . As shown in  FIG.  1 B , the aerosol  240  may be considered to be the drawn aerosol  230  in the first conduit portion  129 A. The drawn aerosol  230  may, subsequently to passing through the first conduit portion  129 A as aerosol  240 , be drawn through the orifice  282  of orifice structure  280  as aerosol  250 . The drawn aerosol  230 , upon being drawn through the orifice  282  as aerosol  250 , may be further drawn through the second conduit portion  129 B of the conduit  129  to the outlet  148  as aerosol  260 . 
     In some example embodiments, the pressure sensor device  172 A may be configured to generate sensor data that, when processed, provides an indication of the pressure of aerosol  240  in the first conduit portion  129 A of the conduit  129 , and the sensor device  172 B may be configured to generate sensor data that, when processed, provides an indication of the pressure of aerosol  260  in the second conduit portion  129 B of the conduit  129 . In some example embodiments, the flow rate of drawn aerosol  230  through a sensor apparatus  100  that includes orifice structure  280  having orifice  282  may be determined based on application of the difference between the pressures indicated by the respective instances of sensor data generated by pressure sensor devices  172 A,  172 B. Various known methods may be used. For example, the difference between the pressures indicated by the respective instances of sensor data generated by pressure sensor devices  172 A,  172 B may be applied to Equation (1) below as a pressure differential “ΔP” to determine the value of a volumetric flow rate “Q” of the drawn aerosol  230  through the sensor apparatus  100 . In Equation (1) below, “ε” is an expansion coefficient associated with compressible media (e.g., gases), “C” is a discharge coefficient, “d” is the internal orifice diameter of orifice  282  under operating conditions, “β” is a ratio of the diameter of the orifice  282  to the diameter of conduit  129 , and “ρ t ” is a density of the aerosol  240  in the conduit portion  129 A.

     It will be understood that the values of “C”, “β”, “ε”, “μ 1 ”, and “d” may be determined through well-known, empirical methods. In some example embodiments, the values of “C”, “β”, “ε”, “ρ 1 ”, and “d”, the value of constant value “K”, a sub-combination thereof, or a combination thereof may be stored in a memory and accessed as part of calculating the value of “Q” according to either Equation (1) or Equation (2). 
     In some example embodiments, one or more of the aforementioned constant values may vary according to the local temperature and/or pressure. Accordingly, the value of K at any given time may be calculated and/or estimated based on the calculated value of ΔP at the same time. In some example embodiments, the temperature sensor device  179  may be configured to measure a local temperature relative to the sensor apparatus  100 , and the value of the value of K at any given time may be determined based on the measured local temperature. For example, in some example embodiments, the value of K may be determined based on applying a temperature determined based on sensor data generated by the temperature sensor device  179  to a look up table that associates temperatures with corresponding values of K. 
     In some example embodiments, a flow rate “Q” and/or constant value “K” may be determined based on accessing a look up table that includes a set of pressure differential ΔP values and associated drawn aerosol  230  flow rate Q values and/or constant K values. The look up table may be generated separately via well-known empirical techniques, for example via drawing various instances of known flow rates of drawn aerosol  230  through the conduit  129  and calculating the corresponding pressure differentials associated with the known flow rates of drawn aerosol  230  to calculate drawn aerosol  230  flow rate Q values, and/or based on drawing various instances of known flow rates of drawn aerosol  230  through the conduit  129  with known pressure differentials and at various known temperatures to calculate corresponding constant K values. 
     In some example embodiments, the sensor apparatus  100 , including the orifice structure  280 , may be configured to enable the pressure sensor devices  172 A,  172 B to generate sensor data that may be processed to enable the determination of a volumetric flow rate Q of the drawn aerosol through the conduit  129  that is equal to or greater than about 5 cubic centimeters per minute. 
     It will be understood that, while the above description relates to the determination of a volumetric flow rate Q of the drawn aerosol  230  through the conduit  129  based on a determined pressure differential, a mass flow rate M of the drawn aerosol  230  through the conduit  129  may be determined via similar methodology. Such methodology may include use of a look up table, via application of pressure differential values to one or more well-known algorithms for determining mass flow rate based on further application of known and stored constant values associated with the drawn aerosol  230  and/or conduit  129 , a sub-combination thereof, a combination thereof, or the like. 
     In some example embodiments, the total amount of an instance of aerosol that is drawn through at least a portion of conduit  129  within any given period of time may be determined simply via known techniques for determining total mass and/or total volume of an instance of fluid passing through a conduit within a time period based on determined mass flow rate and/or volume flow rate values for the fluid during the same time period. For example, a total mass or volume of an instance of aerosol drawn through the conduit  129  within a given period of time may be determined based on 1) for each separate determined (mass or volume) flow rate value associated with the period of time, determining a value for the mass or volume of the instance of aerosol based on multiplication of the flow rate value with a particular time segment value associated with the respective flow rate value and 2) determining a sum of the determined mass or volume values. In another example, a total mass or volume of an instance of aerosol drawn through at least a portion of the conduit  129  within a given period of time may be determined based on 1) applying curve fitting and/or regression (using any various type of well-known algorithm, including any polynomial algorithm) to a series of (mass or volume) flow rate values determined at various separate points in time during the period of time to generate an algorithm of flow rate based on time that at least approximates the determined flow rate values and 2) performing mathematical integration of the algorithm over the period of time to determine a total mass or volume value of the instance of aerosol drawn at least partially through the conduit during the period of time. Other suitable methods may be used. 
     In some example embodiments, the above determinations may be made by one or more elements of control circuitry  171 , based on executing a program of instructions that is stored at a memory of the control circuitry  171  and further based on sensor data received from the pressure sensor devices  172 A,  172 B. 
     In some example embodiments, the sensor apparatus  100  may generate information based on the sensor data generated by the pressure sensor devices  172 A,  172 B, where the information indicates a flow rate of an instance of an aerosol through the sensor apparatus  100 , a duration of the instance of aerosol being drawn through the sensor apparatus  100 , a total amount of the instance of aerosol that is drawn through the sensor apparatus  100 , a sub-combination thereof, or a combination thereof. The instance of aerosol as described above may be an instance of drawn aerosol  230 , but example embodiments are not limited thereto. For example, the instance of aerosol as described above may be an instance of generated aerosol  220 . 
     In some example embodiments, a flow rate of an instance of generated aerosol  220  may be determined based on determining the flow rate of an instance of drawn aerosol  230  that is drawn through the sensor apparatus  100  in accordance with sensor data generated by the pressure sensor devices  172 A,  172 B, accessing a look up table that indicates algorithms and/or multipliers associated with the generated aerosol  220 , and applying the determined flow rate of drawn aerosol  230  to the indicated algorithms and/or multipliers to determine the flow rate of the instance of generated aerosol  220 . The look up table may be generated empirically via well-known techniques. 
     Based on the aforementioned determinations, the actual flow rate and/or total amount of an instance of generated aerosol  220  that is included in a given instance of drawn aerosol  230  may be determined. 
     In some example embodiments, the information that may be generated based on sensor data generated by pressure sensor devices  172 A,  172 B of a sensor apparatus  100 , may be referred to as topography information. The topography information may include a set of information indicating properties of one or more instances of aerosol drawn through a sensor apparatus  100 . The properties of one or more instances of aerosol drawn through a sensor apparatus may be referred to herein as aerosol properties. 
     In some example embodiments, a set of information may indicate time-variation of one or more aerosol properties in association with one or more instances of aerosol drawn through the sensor apparatus  100  over a period of time. The one or more aerosol properties may include a flow rate, amount, time of day, and/or duration of various instances of aerosol drawn through the sensor apparatus  100  over a given period of time. A set of information indicating time-variation of one or more aerosol properties associated with a plurality of instances of aerosol drawn through the sensor apparatus  100  over a period of time may be referred to herein as an aerosol draw pattern. 
     In some example embodiments, an aerosol draw pattern may indicate a historical time-variation of one or more properties associated with a plurality of instances of aerosol drawn through the sensor apparatus  100  over a period of time. Such historical time-variation may be referred to herein as a historical aerosol draw pattern. A historical aerosol draw pattern may be generated based on storing and/or aggregating information generated over time at the sensor apparatus  100  in response to one or more instances of aerosol being drawn through the sensor apparatus  100 . Such aggregated information may include topography information associated with one or more previous instances of aerosol that were drawn through the sensor apparatus  100 . Each separate set of information associated with a separate previous instance of aerosol drawn through the sensor apparatus  100  may be stored, at the sensor apparatus  100  and/or the computing device  302 , as a portion of an instance of topography information associated with the sensor apparatus  100  and/or an ATC supported by the sensor apparatus  100  and/or computing device  302 . The topography information, including the one or more set of information associated with previous instances of aerosol drawn through the sensor apparatus  100  may be processed to determine an aerosol draw pattern associated with at least the one or more previous instances of aerosol, where a portion of the aerosol draw pattern that is associated with the one or more previous instances of aerosol is referred to as the historical aerosol draw pattern. 
     As described herein, an instance of aerosol being drawn through the sensor apparatus  100  may be determined to have started based on a determination, upon processing of information associated with sensor data generated by the pressure sensor devices  172 A,  172 B, a magnitude of a pressure differential between the separate pressures measured by the separate pressure sensor devices  172 A,  172 B at least meets a particular threshold magnitude. In response to such a determination, a start time of the drawing of the instance of aerosol may be determined as the time at which the pressure differential at least meets the particular threshold magnitude. An initial flow rate of aerosol through the sensor apparatus  100  in associated with the instance of aerosol being drawn through the sensor apparatus  100  may be determined based on processing information indicating a pressure differential at the start of the instance of aerosol, information indicating an average pressure differential within a short period of time following the start of the instance of aerosol, or a combination thereof. 
     In some example embodiments, an instance of aerosol may be determined to be ended in response to a determination that the magnitude of the pressure differential between the separate pressures measured by the separate pressure sensor devices  172 A,  172 B, having previously exceeded the particular threshold magnitude at the start of the instance, subsequently falls to equal or be less than the particular threshold magnitude. The time at which the pressure differential falls to equal or be less than the particular threshold magnitude may be determined to be the end time of the instance of aerosol being drawn through the sensor apparatus  100 . Subsequent determined rises of the pressure differential to exceed the particular threshold magnitude may be determined to be indications of a start of a separate, subsequent instance of aerosol being drawn through the sensor apparatus  100 . 
     In some example embodiments, an aerosol draw pattern may indicate a projection of one or more aerosol properties associated with a presently-ongoing instance of aerosol drawn through the sensor apparatus  100  upon a projected completion of the presently-ongoing instance of aerosol. The projection may be based upon a set of information that is recorded by the pressure sensor devices  172 A,  172 B at a detected start of the presently-ongoing instance of aerosol and information associated with a historical aerosol draw pattern. For example, the projection may be based on a determination of an initial flow rate of drawn aerosol  230  through the sensor apparatus  100  at the determined start time of an instance of the drawn aerosol  230  being drawn through the sensor apparatus  100  and a determined average duration of one or more previous instances of aerosol being drawn through the sensor apparatus  100 , as indicated by processing a historical aerosol draw pattern. Accordingly, an aerosol draw pattern may indicate a projection of a total amount of an aerosol to be drawn through the sensor apparatus  100  upon completion of the presently-ongoing instance of aerosol. Such a projection may be referred to herein as a projected aerosol draw pattern, and a portion of the aerosol draw pattern that is associated with a presently-ongoing instance of aerosol being drawn through the sensor apparatus  100  may be referred to as the projected aerosol draw pattern. Accordingly, it will be understood that in some example embodiments, within a given period of time, an aerosol draw pattern may include both a historical aerosol draw pattern, based on one or more previous instances of aerosol, and a projected aerosol draw pattern, based on a presently-ongoing instance of aerosol. 
     In some example embodiments, the sensor apparatus  100  enables the generation of real-time and/or near-real-time streams of information regarding at least the drawn aerosol  230  that is through the sensor apparatus  100 . Such real-time and/or near-real-time streams of information may be used, by the sensor apparatus  100  and/or one or more computing devices communicatively coupled to the sensor apparatus  100 , to generate real-time and/or near-real-time displays of information associated with an aerosol draw pattern corresponding to one or more instances of aerosol drawn through a sensor apparatus  100  to an ATC supported by a computing device, sensor apparatus  100 , or a combination thereof, thereby enabling improved awareness by the ATC of one or more properties associated with one or more aerosol draws. 
     In some example embodiments, the sensor apparatus  100  enables the generation of aerosol draw pattern information based on utilizing a relatively compact sensor apparatus structure that avoids including a sensor device that directly impinges and/or obstructs even a portion of the fluid conduit through which fluid is drawn. In some example embodiments, the sensor apparatus  100  may utilize an interface devices  184  that includes a wireless communication interface to communicate information associated with one or more instances of aerosol drawn through the sensor apparatus  100 . The sensor apparatus  100  may enable the real-time or near real-time generation, monitoring, and/or analysis of topography information that provide an improved indication of properties associated with one or more instances of aerosol drawn through the external tobacco element  200  in the absence of the sensor apparatus  100 . Providing such indications in real-time or near real-time may further enable providing improved awareness of the characteristics of instance of aerosol drawn through the sensor apparatus  100  and may further enable improved, real-time or near real-time control of the flow rate, duration, and/or amount of one or more instances of aerosol through the sensor apparatus  100  over a period of time in accordance with one or more aerosol draw patterns. 
     Still referring to  FIG.  1 B , in some example embodiments, the sensor apparatus  100  may be configured to communicate information to an external, remotely-located computing device via the interface device  184 . In some example embodiments, the interface device  184  may include a communication interface that is configured to communicate, to an external computing device via a communication link, information that includes a sensor data stream that provides a real-time indication of the flow of one or more instances of aerosol drawn through the sensor apparatus  100 , where the information may include sensor data generated by pressure sensor device  172 A, pressure sensor device  172 B, temperature sensor device  179 , a sub-combination thereof, or a combination thereof. The communication interface may be a wireless network communication interface and the communication link may be a wireless network communication link. The information may include processed information generated at sensor apparatus  100  based on sensor data generated by pressure sensor device  172 A, pressure sensor device  172 B, temperature sensor device  179 , a sub-combination thereof, or a combination thereof. In some example embodiments, the interface device  184  may communicate, via a communication link to an external device, a sensor data stream providing a real-time or near-real-time indication of at least one of a flow rate of one or more instances of aerosol through the conduit  129 , a pressure differential, a total to-date amount of an instance of aerosol drawn through the conduit  129  over a period of time, a temperature differential, a sub-combination thereof, or a combination thereof. 
     As described herein, where one or more instances of an aerosol drawn through the sensor apparatus  100  are described, an aerosol draw pattern relating to one or more instances of aerosol drawn through the sensor apparatus  100  are described, a time-variation of a cumulative amount of an aerosol included in one or more instances of aerosol drawn through the sensor apparatus  100 , some combination thereof, or the like, the aerosol may include one or more of drawn aerosol  230  and generated aerosol  220  as described herein. In some example embodiments, the aerosol may include one or more of drawn aerosol  230 , generated aerosol  220 , bypass aerosol  272 , bypass air  274 , remainder generated aerosol  290 , some combination thereof, or the like. 
     Still referring to  FIG.  1 B , the sensor apparatus  100  may include a feedback device  199  that is configured to generate a feedback signal that is observable from an exterior of the sensor apparatus  100  through a port  191  in the housing  110 . The feedback signal may be an audio signal, a visual signal, a vibration signal, a haptic feedback signal, etc., a sub-combination thereof, or a combination thereof. It will be understood that, in some example embodiments, port  191  may be absent from the housing  110 , and the feedback device  199  may be on an outer surface of the housing  110  and/or may at least partially extend through the housing  110  to the outer surface, such that the feedback device  199  may be observable from an exterior of the sensor apparatus  100 . 
     In some example embodiments, the feedback device  199  may be controlled to generate a feedback signal. In some example embodiments, as described further below, the feedback device  199  may generate a particular feedback signal of a plurality of feedback signals based on a determination of whether an aerosol draw pattern of one or more instances of aerosol that are drawn through the sensor apparatus  100  exceed a threshold aerosol draw pattern, where the determination may be made based on processing information associated with sensor data generated by the pressure sensor devices  172 A,  172 B of the sensor apparatus  100 . Accordingly, in some example embodiments, the sensor apparatus  100  may be configured to provide feedback to an adult tobacco consumer (ATC) regarding whether a pattern of one or more instances of aerosol that are drawn through at least a portion of the sensor apparatus  100  conforms to, or exceeds, a threshold aerosol draw pattern, based on generating one or more particular feedback signals. The threshold aerosol draw pattern may be associated with a level of desired generated aerosol  220  drawing through the outlet  148 , such that the feedback signals generated by the feedback device  199  may enable an ATC to monitor one or more instances of aerosol drawn through the sensor device in relation to the level of desired generated aerosol  220  drawing. 
     Still referring to at least  FIG.  1 A- 1 B , in some example embodiments, a sensor apparatus  100  that includes pressure sensor devices  172 A,  172 B and an interface device  184  that includes a communication interface may provide a relatively compact structure that is configured to generate information providing real-time or near-real-time data indication of a flow rate of aerosol drawn from the external tobacco element  200  and through the sensor apparatus  100 . In some example embodiments, based at least in part upon the pressure sensor devices  172 A,  172 B of the sensor apparatus  100  being in hydrodynamic communication with the conduit  129  and not at least partially obstructing the conduit  129 , the structure of the sensor apparatus  100  may enable monitoring of one or more instances of aerosol drawn from the external tobacco element  200  while reducing and/or minimizing any effects of the sensor apparatus itself  100  upon properties of the one or more instances, for example by not limiting the maximum flow rate of aerosol through the conduit  129  to be less than the maximum flow rate of generated aerosol  220  that may be drawn out of the external tobacco element  200  in the absence of a sensor apparatus  100  being coupled to the external tobacco element  200 . 
     In some example embodiments, the interface device  184  may include a wireless network communication interface and thus may enable reduced influence of the sensor apparatus  100  upon instances of aerosol that may be drawn from the external tobacco element  200 . The relatively compact structure of the sensor apparatus  100  and reduced influence of the sensor apparatus  100  upon the flow of aerosol drawn from the external tobacco element  200  may further enable manipulation and/or operation of the sensor apparatus  100  and coupled external tobacco element  200  with reduced physical and/or operational limitations and/or restrictions. In example embodiments, properties may include a flow rate of one or more instances of aerosol, a duration of the one or more instances of aerosol being drawn through the sensor apparatus, a total amount of each instance of aerosol, a time of day at which each instance of aerosol is drawn through the sensor apparatus, a sub-combination thereof, or a combination thereof. Such properties may be referred to herein as aerosol properties, and a time-variation of one or more such properties over a period of time, based on one or more instances of aerosol being drawn through the sensor apparatus over the period of time, may be referred to herein as an aerosol draw pattern. An aerosol draw pattern relating to one or more instances of aerosol that are drawn through at least a portion of the sensor apparatus  100  may correspond to an aerosol draw pattern relating to one or more instances of generated aerosol  220  drawn from the external tobacco element  200  in the absence of the external tobacco element  200  being coupled to the sensor apparatus  100 . 
     As described herein, an aerosol draw pattern relating to one or more instances of aerosol drawn through the sensor apparatus  100  may form at least a portion of topography information. The information generated by the sensor apparatus  100 , which may be associated with said sensor data generated by one or more pressure sensor devices  172 A,  172 B of the sensor apparatus  100 , may be processed to generate topography information that indicates one or more aerosol draw patterns relating to one or more instances of aerosol drawn through the sensor apparatus  100 . As described herein, the processing of information associated with sensor data to generate topography information associated with the sensor apparatus  100  may be performed by at least one device, where the at least one device is the sensor apparatus  100 , a computing device communicatively linked to the interface device  184  of the sensor apparatus  100  via a communication link, or a combination thereof. 
     As described herein, topography information may be processed to generate a particular feedback control signal to cause the feedback device  199  to generate one or more particular feedback signals to provide feedback regarding whether an aerosol draw pattern of one or more instances of aerosol that are drawn through the sensor apparatus  100  conforms to or exceeds a threshold aerosol draw pattern. Accordingly, such feedback signals may enable manual adjustment of an aerosol draw pattern to at least conform to one or more threshold aerosol draw patterns. 
     While  FIG.  1 B  shows pressure sensor devices  172 A,  172 B that are separated from conduit  129  by respective conduits  188 A,  188 B, it will be understood that, in some example embodiments, including for example the example embodiments shown in  FIG.  1 C , one of more of the pressure sensor devices  172 A,  172 B may be located in the conduit structure  120  such that a conduit-proximate surface of each sensor device  172 A,  172 B is flush with the inner surface  123  of the conduit structure  120  that at least partially defines the conduit  129 . 
     In some example embodiments, the interface device  184  may be a manual interface device that is configured to support interactions between an adult tobacco consumer (ATC) and the sensor apparatus  100 . In some example embodiments, the sensor apparatus  100  may be restricted from establishing a communication link with an external device. For example, the interface device  184  may, in some example embodiments, include a display device, one or more buttons, a combination thereof, or the like. In some example embodiments, the interface device  184  may include a touchscreen display device. In some example embodiments, the control circuitry  171  may be configured to generate topography information based on sensor data generated by the pressure sensor devices  172 A,  172 B and may display some or all of the topography information on a display device of interface device  184 . Such a display of topography information may include one or more of the graphs shown in  FIGS.  4 A and  4 B . Some example embodiments may include one or more of these features, and also be able to establish a communication link with an external device. 
       FIG.  1 C  is a cross-sectional view of an assembly  300  according to some example embodiments. As shown in  FIG.  1 C , in some example embodiments, a sensor apparatus  100  may be at least partially similar in structure and configured operation as the sensor apparatus  100  shown in  FIGS.  1 A-B . Elements of the sensor apparatus  100  shown in  FIG.  1 C  that are the same in structure and/or functional configuration as the similarly-labeled elements of the sensor apparatus  100  shown in  FIGS.  1 A- 1 B  are not re-described here. 
     In some example embodiments, topography information may be processed to enable control of the flow rate of one or more aerosols through the sensor apparatus  100 . Control of such flow rate may be based upon comparison of a determined aerosol draw pattern of one or more instances of the one or more aerosols drawn through the sensor apparatus  100  with a threshold aerosol draw pattern. Such control may include adjusting the flow rate of one or more instances of aerosol through at least a portion of the sensor apparatus  100  to adjust an aerosol draw pattern to conform to a threshold aerosol draw pattern. Accordingly, in some example embodiments, the topography information that is generated based on sensor data generated by the pressure sensor devices  172 A,  172 B may enable improved control provided by an assembly  300  that includes the sensor apparatus  100  based on controlling the flow rate of one or more instances of aerosol through at least a portion of the sensor apparatus  100 . Such control may be implemented by sensor apparatus  100 , a computing device that is external to the sensor apparatus  100  and is communicatively linked to a communication interface of the sensor apparatus  100  via a communication link, or a combination thereof. For example, such control may be implemented by a computing device that is external to the sensor apparatus  100  and is communicatively linked to a wireless network communication interface and/or wired network communication interface of an interface device  184  of the sensor apparatus  100  via a wireless communication link and/or wired communication link. 
     As shown in  FIG.  1 C , in some example embodiments, a sensor apparatus  100  may include one or more flow control devices  292 ,  294 ,  296 ,  298  that are configured to adjustably control a flow rate of at least a portion of an instance of generated aerosol  220  through one or more portions of the conduit  129 , a flow of an instance of drawn aerosol  230  through one or more portions of the conduit  129 , or a combination thereof. The sensor apparatus  100  may be configured to adjustably control the one or more flow control devices  292 ,  294 ,  296 ,  298  to adjustably control the flow of the drawn aerosol  230 , generated aerosol  220 , or combination thereof through one or more portions of the conduit  129 . In some example embodiments, the sensor apparatus  100  may adjustably control the one or more flow control devices  292 ,  294 ,  296 ,  298  based on a feedback control signal that is received at the communication interface of the sensor apparatus  100 , which may be included in an interface device  184  thereof, from an external computing device. 
     In some example embodiments, the adjustable valve device  292  may adjustably control a cross-sectional flow area of at least a limited portion of the conduit  129  to control a flow of the generated aerosol  220 , as a flow of remainder generated aerosol  290  that comprises at least a portion of drawn aerosol  230 , through at least a portion of the sensor apparatus  100  to outlet opening  148 . The remainder generated aerosol  290  may be referred to as a first portion of the generated aerosol  220 . The adjustable valve device  292  may be any known adjustable valve device that may adjustably control a flow of a fluid through a conduit, including a ball valve, gate valve, adjustable orifice, or the like. 
     As shown in  FIG.  1 C , in some example embodiments, the conduit  129  may be partitioned into an inlet portion  291  and a remainder portion  293  that are each at least partially defined by the adjustable valve device  292 , where the inlet portion  291  is defined as a portion of conduit  129  that extends between the adjustable valve device  292  and the inlet opening  125 , and the remainder portion  293  is defined as a portion of conduit  129  that extends between the adjustable valve device  292  and the outlet opening  127 . In some example embodiments, the portion of conduit portion  129 A within the remainder portion  293  may be conduit portion  299 , and the pressure sensor device  172 A may generate sensor data indicating a pressure of aerosol in conduit portion  299 . 
     In some example embodiments, the adjustable vent device  294  may define and adjustably control a cross-sectional flow area of a bypass vent conduit that branches from the inlet portion  291  of conduit  129  to the ambient environment  310 , independently of the remainder portion  293  of conduit  129  that extends to the outlet opening  127 . The adjustable vent device  294  may adjustably re-direct at least a portion of the generated aerosol  220  that is drawn into the conduit  129  from the inlet opening  125  to flow into the ambient environment  310  as bypass aerosol  272 , independently of being drawn through the remainder portion  293  of the conduit  129  to the outlet opening  148  as at least a portion of drawn aerosol  230 . As described herein, the bypass aerosol  272  may be a second portion of the generated aerosol  220 . In some example embodiments, the remainder generated aerosol  290  and the bypass aerosol  272  may be separate portions of the generated aerosol  220  that are drawn and/or directed through separate portions of the sensor apparatus  100 . The remainder generated aerosol  290  may be a limited portion or an entire portion of the generated aerosol  220 . The bypass aerosol  272  may be a limited portion or an entire portion of the generated aerosol  220 . 
     In some example embodiments, the pump device  298  may induce a flow of the bypass aerosol  272  through to the ambient environment  310  to overcome a pressure gradient from the ambient environment  310  to the inlet portion  291  of the conduit  129 . The pump device  298  may be any known pump device. For example, the pump device  298  may be a centrifugal pump. 
     In some example embodiments, the adjustable vent device  294 , pump device  298 , and adjustable valve device  292  may adjustably restrict a portion of generated aerosol  220  from being drawn through the adjustable valve device  292  and may re-direct said portion of the generated aerosol  220  into the ambient environment  310  through the adjustable vent device  294  and pump device  298  as bypass aerosol  272 , thereby at least partially mitigating pressure buildup within the inlet portion  291  of the conduit  129 . Accordingly, a limited portion of the generated aerosol  220  may be drawn through the adjustable valve device  292  as remainder generated aerosol  290 , such that the drawn aerosol  230  includes a limited portion of the generated aerosol  220 . In some example embodiments, an entirety of the generated aerosol  220  may be re-directed to the ambient environment  310  as bypass aerosol  272 , such that the drawn aerosol  230  omits remainder generated aerosol  290 . 
     Adjustable intake device  296  may define and adjustably control a cross-sectional flow area of another bypass vent conduit that branches from the ambient environment  310  to the remainder portion  293  of conduit  129 , independently of the inlet opening  125 . The adjustable intake device  296  may adjustably draw a stream of ambient air from the ambient environment  310  into remainder portion  293  of the conduit  129  as bypass air  274 , independently of the external tobacco element  200 , inlet portion  291 , and/or inlet opening  125  and thus independently of generated aerosol  220  that is drawn into the conduit  129  through the inlet opening  125 . The bypass air  274  may, as shown in  FIG.  1 C , flow through the remainder portion  293  of the conduit  129  as drawn air  275 . Thus, the drawn aerosol  230  may include a mixture of the remainder generated aerosol  290  and the drawn air  275 , such that the drawn aerosol  230  is diluted of generated aerosol  220 , thereby reducing a proportion of drawn aerosol  230  that include generated aerosol  220  and/or remainder generated aerosol  290 . 
     The adjustable intake device  296  and adjustable valve device  292  may adjustably restrict a portion of generated aerosol  220  from passing through the adjustable valve device  292  towards outlet opening  127  and may draw at least some ambient air from the ambient environment  310  into the conduit  129  to replace the portion of generated aerosol  220  that is restricted from passing through the adjustable valve device  292 . Accordingly, the drawn aerosol  230  may include an adjustably controlled amount and/or proportion of the remainder generated aerosol  290  that is balanced with drawn air  275  so that the drawn aerosol  230  has a total flow rate that approximates (for example, inclusively between 90% and 110% of) the total flow rate of generated aerosol  220  that is received into conduit  129  through inlet opening  125 . Accordingly, the amount of generated aerosol  220  that is included in the drawn aerosol  230 , as the remainder generated aerosol  290 , may be adjustably controlled without significant variation in flow of the drawn aerosol  230  from the flow of the generated aerosol  220  drawn into the sensor apparatus  100 . 
     The adjustable vent device  294  and the adjustable intake device  296  may each be a one-way valve that is configured to enable only a one-way flow of fluid. For example, the adjustable vent device  294  may be a check valve that is configured to adjustably enable and adjustably control a flow of bypass aerosol  272  that is restricted, based on the structure of the check valve, to flow only from the conduit  129  to the ambient environment  310 , and the adjustable intake device  296  may be a check valve that is configured to adjustably enable and adjustably control a flow of bypass air  274  that is restricted, based on the structure of the check valve, to flow only from the ambient environment  310  to the conduit  129 . 
     The sensor apparatus  100  may be configured to, based on operation of the control circuitry  171 , adjustably control adjustable valve device  292 , adjustable vent device  294 , adjustable intake device  296 , pump device  298 , a sub-combination thereof, or a combination thereof, to adjustably control the amount and/or proportion of generated aerosol  220 , that is included in the drawn aerosol  230  as remainder generated aerosol  290 . The adjustable valve device  292 , adjustable vent device  294 , adjustable intake device  296 , and/or pump device  298  may be adjustably controlled, based on processing sensor data generated by pressure sensor devices  172 A,  172 B, to cause the flow rate of remainder generated aerosol  290  to be within a particular margin of a particular flow rate. 
     In some example embodiments, the sensor apparatus  100  may generate information, and communicate information to an external device, where the information indicates an operating configuration of one or more flow control devices included in the sensor apparatus  100 , including one or more of the adjustable flow control devices  292 ,  294 ,  296 ,  298  as described herein, where the determination is based on a configuration generated at the sensor apparatus  100 . A flow rate of bypass aerosol  272 , bypass air  274 , generated aerosol  220 , remainder generated aerosol  290 , drawn air  275 , a sub-combination thereof, or a combination thereof drawn through the sensor apparatus  100  may be determined based on information, generated at the sensor apparatus  100 , that indicates the flow rate of an instance of aerosol through the sensor apparatus  100 , duration of the instance of aerosol being drawn through the sensor apparatus  100 , total amount of the instance of aerosol that is drawn through the sensor apparatus  100 , information indicating a configuration of one or more of the adjustable flow control devices  292 ,  294 ,  296 ,  298  concurrently with the instance of aerosol being drawn through the sensor apparatus  100 , a sub-combination thereof, or a combination thereof. The instance of aerosol as described above may be an instance of drawn aerosol  230 , but example embodiments are not limited thereto. For example, instance of aerosol as described above may be an instance of remainder generated aerosol  290 . 
     In some example embodiments, a flow rate of bypass aerosol  272 , bypass air  274 , generated aerosol  220 , remainder generated aerosol  290 , drawn air  275 , a sub-combination thereof, or a combination thereof, may be determined based on determining the flow rate of drawn aerosol  230  through the sensor apparatus  100  based on information associated with sensor data generated by the pressure sensor devices  172 A,  172 B, determining the configurations of the one or more flow control devices  292 ,  294 ,  296 ,  298 , accessing a look up table that indicates algorithms and/or multipliers, associated with the respective bypass aerosol  272 , bypass air  274 , generated aerosol  220 , remainder generated aerosol  290 , drawn air  275 , a sub-combination thereof, or a combination thereof, that correspond to the determined configurations of the one or more flow control devices  292 ,  294 ,  296 ,  298 , and applying the determined flow rate of drawn aerosol  230  to the indicated algorithms and/or multipliers to determine the flow rates of bypass aerosol  272 , bypass air  274 , generated aerosol  220 , remainder generated aerosol  290 , drawn air  275 , a sub-combination thereof, or a combination thereof. The look up table may be generated empirically via well-known techniques. 
     Based on the aforementioned determinations, the flow rate and amount of an instance of generated aerosol  220  that is included in a given instance of drawn aerosol  230  as an instance of remainder generated aerosol  290  may be determined in some example embodiments. 
     While the example embodiments shown in  FIGS.  1 A- 1 C  include an assembly  300  wherein the sensor apparatus  100  is coupled to an external tobacco element  200  that may generate the generated aerosol  220 , it will be understood that, in some example embodiments, the assembly  300  may include a sensor apparatus  100  that is coupled to an external element that is an electronic vaping device that is configured to generate the generated aerosol  220 , instead of being coupled to an external tobacco element  200 . In some example embodiments, the electronic vaping device may generate the generated aerosol  220  based on heating a pre-vapor formulation. In some example embodiments, the electronic vaping device may not include any tobacco. In some example embodiments, the electronic vaping device may generate the generated aerosol  220  based on applying mechanical force to a pre-vapor formulation. Accordingly, where example embodiments described herein may be described with reference to a generated aerosol  220  received from an external tobacco element  200  at a sensor apparatus  100 , it will be understood that the generated aerosol  220 , in some example embodiments, may be received from an external tobacco element  200  coupled to a sensor apparatus  100  or, in some example embodiments may be received from an electronic vaping device coupled to a sensor apparatus  100 , from an electronic nicotine delivery system coupled to a sensor apparatus  100 , or from any device that may generate an aerosol coupled to a sensor apparatus  100 . 
       FIG.  2    is a schematic of a system configured to enable display and/or communication of topography information at one or more devices based on sensor data generated at a sensor apparatus according to some example embodiments. 
     In some example embodiments, an assembly  300 , including a sensor apparatus  100  and an external tobacco element  200  as shown in  FIGS.  1 A- 1 C , may be communicatively coupled to one or more external computing devices  302  of a system  301  configured to enable display and/or communication of topography information at one or more devices based on sensor data generated at the sensor apparatus  100 , via one or more communication links  304 . 
     In some example embodiments, a computing device  302  communicatively coupled to the assembly  300  may generate one or more feedback control signals based on generated topography information, including a determined aerosol draw pattern associated with one or more instances of an aerosol drawn through the sensor apparatus  100 . In some example embodiments, the one or more feedback control signals may cause a sensor apparatus  100  to control a feedback device  199  thereof to generate one or more feedback signals based on a determination of whether one or more aerosol properties of an aerosol draw pattern exceeds a corresponding one or more threshold aerosol properties of a threshold aerosol draw pattern, thereby exceeding the threshold aerosol draw pattern. In some example embodiments, the one or more feedback control signals may cause a sensor apparatus  100  to control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to control an amount, flow rate, and/or proportion of remainder generated aerosol  290  that is included in one or more instances of drawn aerosol  230  that are drawn through the sensor apparatus  100 , based on a determination of whether one or more aerosol properties of an aerosol draw pattern exceeds a corresponding one or more threshold aerosol properties of a threshold aerosol draw pattern. 
     In some example embodiments, an aerosol property of an aerosol draw pattern includes an indication of a time variation of a cumulative amount of remainder generated aerosol  290  included in one or more instances of drawn aerosol  230  drawn through a sensor apparatus  100  over a period of time, and the determination of whether the aerosol draw pattern exceeds a corresponding threshold aerosol draw pattern includes determining, at a given time, whether a cumulative amount of remainder generated aerosol  290  included in one or more instances of drawn aerosol  230  drawn through a sensor apparatus  100  during the period of time up to the given time exceeds a threshold cumulative amount of remainder generated aerosol  290 , of the threshold aerosol draw pattern, that may be included in one or more instances of drawn aerosol  230  drawn through the sensor apparatus in the same period of time up to the same given time. 
     In some example embodiments, the threshold aerosol draw pattern may be expressed as an algorithmic expression of the threshold cumulative remainder generated aerosol  290  at any given time within a given period of time as a function of the given elapsed time from a start of the time period. Various known methods may be used. For example, the threshold cumulative remainder generated aerosol  290  may be expressed as a function y=xa, where x is the elapsed time, x=0 is the start of the time period, a is a constant value, and y is the threshold cumulative remainder generated aerosol  290 . In another example, the threshold cumulative remainder generated aerosol  290  may be expressed as a function y=ax 2 +bx+c, where x is the elapsed time, x=0 is the start of the time period, a, b, and c are constant values, and y is the threshold cumulative remainder generated aerosol  290 . The threshold aerosol draw pattern may define a time-variation of threshold cumulative remainder generated aerosol  290  that may be drawn through sensor apparatus  100  over a particular period of time. 
     In some example embodiments, an aerosol draw pattern may be determined to exceed a corresponding threshold aerosol draw pattern based on a determination that an aerosol property of the aerosol draw pattern has a value that exceeds a value of a corresponding threshold aerosol property of a corresponding threshold aerosol draw pattern. For example, in response to a determination that a historical aerosol draw pattern indicates a cumulative amount of remainder generated aerosol  290  that has been drawn through sensor apparatus  100  over a particular period of time is greater than a value of a threshold cumulative amount, as indicated by a corresponding threshold aerosol draw pattern, of remainder generated aerosol  290  that may be drawn through sensor apparatus  100  over the same particular period of time, the historical aerosol draw pattern may be determined to have exceeded the corresponding threshold aerosol draw pattern. In another example, in response to a determination that the historical aerosol draw pattern indicates that the cumulative amount of remainder generated aerosol  290  that has been drawn through sensor apparatus  100  over the particular period of time is equal to or less than the value of a threshold cumulative amount, as indicated by the corresponding threshold aerosol draw pattern, of remainder generated aerosol  290  that may be drawn through sensor apparatus  100  over the same particular period of time, the historical aerosol draw pattern may be determined to have conformed to the corresponding threshold aerosol draw pattern. 
     In some example embodiments, a feedback control signal may be different based on whether an aerosol draw pattern, generated based on information generated at a sensor apparatus  100 , is determined to exceed or conform to a corresponding threshold aerosol draw pattern. For example, the sensor apparatus  100  may be caused to control a feedback device  199  to generate different feedback signals based on whether the aerosol draw pattern exceeds or conforms to the corresponding threshold aerosol draw pattern. The different feedback signals may provide an externally-observable indication of whether one or more instances of aerosol draws through the sensor apparatus  100 , as represented by an aerosol draw pattern, are conforming to a threshold aerosol draw pattern, thereby enabling an adult tobacco consumer (ATC) associated with the sensor apparatus  100  to monitor comparative performance of the aerosol draw pattern against the threshold aerosol draw pattern and potentially adjust one or more aerosol properties of the aerosol draw pattern to at least conform to the threshold aerosol draw pattern, thereby enabling improved control of operation of assembly  300 . 
     In another example, the sensor apparatus  100  may be caused to control one or more flow control devices  292 ,  294 ,  296 ,  298  to implement different adjustments to flow of one or more instances of at least the remainder generated aerosol  290  through the sensor apparatus  100  based on whether the aerosol draw pattern exceeds or conforms to the corresponding threshold aerosol draw pattern. As a result, the sensor apparatus  100  may provide improved control over the drawing of generated aerosol  220  from an external tobacco element  200  and at least partially through sensor apparatus  100  in drawn aerosol  230 , as remainder generated aerosol  290 , and thus provide improved control of operation of assembly  300 . 
       FIGS.  3 A and  3 B  are flowcharts illustrating operations of a computing device to adjustably control a sensor apparatus via feedback control signals based on information received from a sensor apparatus according to some example embodiments. The operations illustrated in  FIGS.  3 A and  3 B  may be implemented, in whole or in part, by one or more portions of any embodiment of at least one device of computing device  302 , sensor apparatus  100 , or a combination thereof, as described herein. For example, the operations illustrated in  FIGS.  3 A and  3 B  may be implemented based on a processor included in the computing device  302  executing a program of instructions stored in a memory of the computing device  302 . In another example, the operations illustrated in  FIGS.  3 A and  3 B  may be implemented based on a processor included in the sensor apparatus  100  executing a program of instructions stored in a memory of the sensor apparatus  100 . 
     Referring first to  FIG.  3 A , at S 502 , one or more instances of information are received from a sensor apparatus  100 , where the one or more instances of information include information associated with sensor data generated at the sensor apparatus  100 . Such information may include information associated with one or more instances of aerosol that may be drawn through the sensor apparatus  100  over a period of time, and may include information associated with one or more complete instances of aerosol that were previously drawn through the sensor apparatus, information associated with a presently-ongoing instance of aerosol that is presently being drawn through the sensor apparatus  100 , or a combination thereof. Such information may include, for example, information indicating separate pressures measured by separate pressure sensor devices  172 A,  172 B of the sensor apparatus  100 . 
     At S 504 , the one or more instances of information are processed to generate and/or update an instance of topography information, where the topography information may include information indicating an aerosol draw pattern associated with one or more instances of aerosol previously drawn and/or presently being drawn through the sensor apparatus  100 . For example, at S 504 , the one or more instances of information may be processed to generate an aerosol draw pattern that indicates historical time variation of one or more aerosol properties of one or more previous instances of an aerosol drawn through the sensor apparatus  100  during a particular period of time and a projection of future time variation of the one or more aerosol properties upon completion of a presently-ongoing instance of aerosol presently being drawn through the sensor apparatus  100 , as indicated by information received from the sensor apparatus  100  at S 502 . 
     At S 505 , one or more threshold aerosol properties of a threshold aerosol draw pattern may be determined, selected, and/or received from an interface of the computing device  302 . For example, a threshold aerosol property may include a specification of a threshold cumulative amount of remainder generated aerosol  290  included in the cumulative amount of drawn aerosol  230  that is drawn through the sensor apparatus  100  within a particular period of time and a threshold rate of time-variation of the threshold cumulative amount of remainder generated aerosol  290  included in the cumulative drawn aerosol  230  over the period of time. 
     At S 506 , a threshold aerosol draw pattern is determined, based at least in part upon the aerosol draw pattern that is determined at S 504  and/or the threshold aerosol properties received, selected, and/or determined at S 505 . As described above, the threshold aerosol draw pattern may be expressed as an algorithmic expression of the threshold cumulative remainder generated aerosol  290  included in the cumulative drawn aerosol  230  at any given time within a given period of time as a function of the given elapsed time from a start of the time period. 
     At S 508 , the sensor apparatus  100  may be controlled, according to one or more feedback control signals, based on whether the aerosol draw pattern that is determined at S 504  exceeds or conforms to the threshold aerosol draw pattern that is determined at S 506 . As described below with reference to  FIG.  3 B , such control may include controlling a feedback device  199  to generate one or more particular feedback signals and/or controlling one or more flow control devices  292 ,  294 ,  296 ,  298  to cause the time-variation of the cumulative amount of remainder generated aerosol  290  drawn through the sensor apparatus  100  during the time period to not exceed a time-varying threshold cumulative amount of remainder generated aerosol  290  as defined by the threshold aerosol draw pattern. 
     At S 509 , topography information may be displayed in a graphical display interface of computing device  302 . The displayed topography information may include information indicating time-variation of one or more particular aerosol properties of the determined aerosol draw pattern, information indicating time variation of one or more threshold aerosol properties of the threshold aerosol draw pattern, information indicating one or more instances of aerosol drawn through the sensor apparatus  100  during a time period, a sub-combination thereof, or a combination thereof. As shown in  FIG.  3 A , the displaying at S 509  may be performed concurrently with performing one or more of S 505 -S 508 . 
     In some example embodiments, operation S 508  may be omitted and topography information may be displayed, at S 509 , without any control of any portion of the sensor apparatus  100  via one or more feedback control signals. In some example embodiments, operations S 505  and S 506  may be omitted in addition to operation S 508  being omitted, and the topography information displayed at S 509  may omit any display of information associated with any threshold aerosol draw pattern. 
     Referring now to  FIG.  3 B , operation S 508  may include various operations S 510  through S 524 . 
     At S 510 , one or more aerosol properties of the projected aerosol draw pattern is compared with a corresponding one or more threshold aerosol properties associated with the threshold aerosol draw pattern. For example, as described above with reference to S 504 , a projected aerosol draw pattern may be generated based on the historical aerosol draw pattern and information, received at S 502 , associated with a presently-ongoing instance of aerosol being drawn through the sensor apparatus  100 , and a projected cumulative remainder generated aerosol  290  drawn during the current time period upon completion of the instance of aerosol may be compared with a corresponding threshold cumulative remainder generated aerosol  290  amount of the threshold aerosol draw pattern that associated with the same time period as the time period in which the presently ongoing instance of aerosol is projected to be completed. 
     At S 516 , a determination is made regarding whether the one or more aerosol properties of the determined aerosol draw pattern exceed or conform to the corresponding one or more threshold aerosol properties of the threshold aerosol draw pattern, such that the determined aerosol draw pattern is determined to exceed or conform to the threshold aerosol draw pattern. 
     Based on the determination at S 516 , as shown at S 522 , S 524 , or a combination thereof, one or more feedback control signals may be generated to control one or more aspects of the sensor apparatus  100 . One or more of operations S 522  and S 524  may be omitted. 
     In one example, if the determined aerosol draw pattern conforms to the threshold aerosol draw pattern at S 516 , at S 522  a feedback control signal may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate an externally observable feedback signal to indicate that the aerosol draw pattern conforms to the threshold aerosol draw pattern. In another example, if the determined aerosol draw pattern conforms to the threshold aerosol draw pattern at S 516 , at S 524  a feedback control signal may be generated to cause one or more flow control devices of the sensor apparatus  100  to enable an entirety of the generated aerosol  220  to be included in the drawn aerosol  230 , for example without augmenting the drawn aerosol  230  with bypass air  274 , during the remainder of the ongoing instance of drawn aerosol  230  and/or a subsequent instance of drawn aerosol  230 . 
     In another example, if the determined aerosol draw pattern exceeds the threshold aerosol draw pattern at S 516 , at S 522  a feedback control signal may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate an externally observable feedback signal to indicate that the aerosol draw pattern exceeds the particular aerosol draw pattern. In addition, if the determined aerosol draw pattern exceeds the threshold aerosol draw pattern at S 516 , at S 524  a feedback control signal may be generated to cause one or more flow control devices of the sensor apparatus  100  to adjustably control an amount and/or proportion of the remainder generated aerosol  290  to be included in the ongoing instance and/or subsequent instances of drawn aerosol  230  to be a limited portion of the generated aerosol  220 , such that at least a portion of the generated aerosol  220  is directed to the ambient environment  310  independently of a remainder of the conduit  129  as bypass aerosol  272 . In addition, bypass air  274  may be caused to be drawn into conduit  129  to mitigate flow rate variation between the flow rates of drawn aerosol  230  and generated aerosol  220 . 
     Accordingly, at S 524 , the sensor apparatus  100  may be configured to adjustably control one or more flow control devices  292 ,  294 ,  296 ,  298  to cause one or more aspects of the flow of a drawn aerosol  230 , in one or more instances of drawn aerosol  230 , to conform to the threshold aerosol draw pattern, for example based on controlling the proportion and/or amount of remainder generated aerosol  290  included in one or more instances of drawn aerosol  230  to cause a cumulative amount of remainder generated aerosol  290  included in the cumulative drawn aerosol  230  over a period of time to not exceed a threshold cumulative amount of remainder generated aerosol  290  that is defined by the particular aerosol draw pattern. 
     At S 524 , the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100  may be controlled to control the amount and/or proportion of generated aerosol  220  included in the drawn aerosol  230  as remainder generated aerosol  290  without substantial variation in the flow rate of drawn aerosol  230 . Substantial variation in the flow rate of the drawn aerosol  230  may include a variation of more than 10% of the flow rate of the drawn aerosol  230  from a base flow rate of the drawn aerosol that corresponds to none of the generated aerosol  220  being directed away from the outlet  148  as bypass aerosol  272 . Such control may first include determining a target flow rate of the drawn aerosol  230 . The target flow rate may be determined to be identical to a determined initial flow rate of an ongoing instance of drawn aerosol  230 , a determined flow rate associated with instances of drawn aerosol associated with the present point in time during the present period of time, as defined by the historical aerosol draw pattern, a sub-combination thereof, or a combination thereof. Additionally, the control may include determining a target amount, proportion, and/or flow rate of remainder generated aerosol  290  in the target flow rate of drawn aerosol  230 . Such determination may be based on determining a maximum amount, proportion, and/or flow rate of remainder generated aerosol  290  included in the current instance and/or subsequent instance of drawn aerosol  230  that causes the cumulative amount of generated aerosol  220  included in the cumulative drawn aerosol  230  during the given time period to not exceed the threshold cumulative generated aerosol at the given time as defined by the threshold aerosol draw pattern. 
     The control may further include determining a configuration of one or more flow control devices  292 ,  294 , and  296  included in the sensor apparatus  100  that are associated with the determined target flow rate of drawn aerosol  230  and determined maximum amount, proportion, and/or flow rate of remainder generated aerosol  290  included in the current, ongoing instance and/or subsequent instance of drawn aerosol  230 . Such a determining may include accessing a look up table that correlates various values of drawn aerosol  230  flow rate and amount, proportion, and/or flow rate of remainder generated aerosol  290  with a corresponding set of configurations of one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 . Based on the determined configuration of the flow control device(s) of the sensor apparatus  100 , a set of feedback control signals that cause the sensor apparatus  100  to control the one or more flow control devices thereof to achieve the determined configuration may be generated and may be transmitted to the sensor apparatus  100  to implement said determined configuration. The look up table may be generated empirically via well-known techniques. 
       FIGS.  4 A and  4 B  illustrate graphical representations of topography information generated based on processing information generated at a sensor apparatus according to some example embodiments. 
     The graphical representations (also referred to herein as displays and/or displayed instances of topography information) illustrated in  FIGS.  4 A and  4 B  may be generated and/or updated, in whole or in part, by one or more portions of any embodiment of one or more computing devices  302  and/or sensor apparatuses  100  as described herein. For example, the graphical representations illustrated in  FIGS.  4 A and  4 B  may be generated by a processor included in the computing device  302  executing a program of instructions stored in a memory of the computing device  302 . In another example, the graphical representations illustrated in  FIGS.  4 A and  4 B  may be generated by a processor included in the control circuitry  171  of the sensor apparatus  100  executing a program of instructions stored in a memory of the control circuitry  171 . 
     Referring now to  FIG.  4 A , a graphical representation  400 A of an aerosol draw pattern  420  of one or more instances of aerosol drawn through a sensor apparatus  100  over a period of time t 0 -t 24  may be generated based on topography information, where the topography information is generated based on sensor data generated by pressure sensor devices  172 A,  172 B of the sensor apparatus  100  over the period of time t 0 -t 24 . Graphical representation  400 A may be a two-dimensional chart, where axis  404  represents the cumulative amount of an aerosol included in one or more instances of an aerosol drawn through the sensor apparatus  100  during a period of time t 0 -t 24  as shown in  FIG.  4 A , and where axis  406  represents time/duration. 
     Still referring to  FIG.  4 A , graphical representation  400 A may include an aerosol draw pattern  420  which illustrates a time variation of the cumulative amount of an aerosol included in one or more instances I 11  to I 1N  of an aerosol drawn through the sensor apparatus  100  during the given time period t 0 -t 24  as shown in  FIG.  4 A  (N being a positive integer). The aerosol draw pattern  420 , which illustrates the time variation of the cumulative amount of an aerosol from a null value at the start t 0  of the time period t 0 -t 24  to a total cumulative amount  421  at the end t 24  of the time period t 0 -t 24  may be generated based on the aforementioned topography information. 
     Still referring to  FIG.  4 A , graphical representation  400 A may further include representations of the amount of aerosol included in each instance I 1  to I N  of aerosol that is drawn through the sensor apparatus  100  during the time period t 0 -t 24 . As shown, each representation of an instance I 1  to I N  in representation  400 A has a y-axis dimension that is proportional to a flow rate of the given instance I 1  to I N  of aerosol and an x-axis dimension that is proportional to a duration of the given instance I 1  to I N  of aerosol. Accordingly, in some example embodiments, the area of the representation of the given instance I 1  to I N  is proportional to the total amount of aerosol included in the given instance I 1  to I N  of aerosol that is drawn through the sensor apparatus  100 . 
     As shown in  FIG.  4 A , the time-variation of the cumulative amount of aerosol as shown in the aerosol draw pattern  420  is based on the time of each instance I 1  to I N  during the time period and the amount aerosol included in each instance as indicated by the representations I 1  to I N . 
     Graphical representation  400 A may be updated over time to include new representations of instances I 1  to I N  of aerosol drawn through the sensor apparatus  100  and/or to update the aerosol draw pattern  420  based on information received from the sensor apparatus  100  over time during one or more time periods. 
     In some example embodiments, the one or more instances of aerosol as indicated in the graphical representation  400 A may be one or more instances of the drawn aerosol  230 , and the cumulative amount of an aerosol included in one or more instances of an aerosol drawn through the sensor apparatus  100  may be a cumulative amount of the drawn aerosol  230  included in the one or more instances of drawn aerosol  230  that are drawn through the sensor apparatus  100 . It will be understood that the aerosol as indicated in the graphical representation may be different from the drawn aerosol  230 . For example, the one or more instances of aerosol as indicated in the graphical representation  400 A may be one or more instances of the remainder generated aerosol  290 , and the cumulative amount of an aerosol included in one or more instances of an aerosol drawn through the sensor apparatus  100  may be a cumulative amount of the remainder generated aerosol  290  that is drawn through the sensor apparatus  100 . 
     It will be understood, in some example embodiments, that the aerosol for which a time-variation of cumulative amount is shown by the aerosol draw pattern  420  may be different than the aerosol for which the one or more instances are shown. For example, in some example embodiments, the aerosol draw pattern  420  indicated in the graphical representation  400 A may indicate a time-variation of the cumulative amount of remainder generated aerosol  290  that is included in one or more instances of drawn aerosol  230  that are drawn through the sensor apparatus  100  over a period of time t 0 -t 24 . 
     Still referring to  FIG.  4 A , the graphical representation  400 A may include a simultaneously display of an aerosol draw pattern  420  and a threshold aerosol draw pattern  430 . Accordingly, the variation in the aerosol draw pattern  420  in relation to the threshold aerosol draw pattern  430  may be more readily observed and understood. 
     As shown in  FIG.  4 A , the threshold aerosol draw pattern  430  may be represented by an algorithm, including a linear algorithm as shown, where the threshold aerosol draw pattern  430  is associated with a threshold aerosol property that is a total threshold cumulative amount  431 , for a given time period, which may be set to be less than the total cumulative amount  421  of the aerosol draw pattern  420 . The threshold aerosol draw pattern  430  may be determined such that the total threshold cumulative amount  431  resulting from the threshold aerosol draw pattern  430 , for a given time period, is less than the total cumulative amount  421 , for a given time period, by at least a threshold amount and/or proportion. In an example, threshold aerosol draw pattern  430  may be a linear algorithm where the value of the total threshold cumulative amount  431  is at least 10% less than total cumulative amount  421 . In some example embodiments, the threshold aerosol draw pattern  430  may be repeatedly adjusted over time, such that the total threshold cumulative amount  431  in a given time period is revised to be less than the total cumulative amount  421  for a previous time period. Accordingly, the total cumulative amount of aerosol drawn through the sensor apparatus  100  may be progressively reduced over time. 
     As described herein with regard to  FIGS.  4 A- 4 B  and as described herein with reference to  FIGS.  3 A- 3 B , one or more feedback control signals may be generated based on whether the aerosol draw pattern  420  conforms to the threshold aerosol draw pattern  430  or exceeds the threshold aerosol draw pattern  430  at a given time. Accordingly, based on generating one or more feedback control signals based on the threshold aerosol draw pattern  430 , one or more instances of aerosol drawn through the sensor apparatus  100  in a given time period may be controlled in relation to a historical aerosol draw pattern as indicated by the topography information. 
     Still referring to  FIG.  4 A , graphical representation  400 A illustrates an aerosol draw pattern  420 , which indicates the time-variation of the cumulative amount of an aerosol drawn through the sensor apparatus  100  over a time period, being compared against a threshold aerosol draw pattern  430 , which indicates the time-variation of the threshold cumulative amount of the aerosol drawn through the sensor apparatus  100  over the same time period, to trigger the generation of feedback control signals to provide an indication, at various times during the time period of whether the aerosol draw pattern  420  is exceeding or conforming to the threshold aerosol draw pattern  430 . Such an indication may be provided via one or more feedback signals generated by a feedback device  199  of a sensor apparatus  100 . Such an indication may be provided via an indication provided on a display interface of a computing device  302 , a display device of the sensor apparatus  100 , some combination thereof, or the like. 
     As shown at  FIG.  4 A , the cumulative amounts of aerosol of both the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  are set to a null value at the start t 0  of the time period. The threshold cumulative amount of aerosol of the threshold aerosol draw pattern  430  may increase over time during the time period from to t 0 -t 24  according to a linear algorithm that defines the threshold aerosol draw pattern  430 , while the cumulative amount of aerosol of the aerosol draw pattern  420  \ increases in accordance with the amount of aerosol that is determined, based on sensor data generated by pressure sensor devices  172 A,  172 B, to be actually drawn through the sensor apparatus  100  in accordance with instances t 21  to I 25  of aerosol within a given time period t 0  to t 24  and at the respective times that the instances occur. 
     In some example embodiments, a feedback device  199  may be adjustably controlled, based on a determination, at the detection of each instance I 21  to I 25  of drawn aerosol  230 , of whether an actual and/or projected cumulative amount of aerosol drawn through the sensor apparatus  100  is greater than the corresponding threshold cumulative amount of aerosol as indicated by the threshold aerosol draw pattern  430 . 
     At time t 11 , where instance I 11  of aerosol is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 11  of the aerosol is determined, the projected cumulative amount  461 A of the aerosol that will be drawn through the sensor apparatus  100  upon completion of the presently ongoing instance I 11  of the aerosol may be determined to be less than the corresponding threshold cumulative amount  461 B at time t 11  by difference D 11 . In response to such a determination, one or more feedback control signals may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate a first externally-observable feedback signal. In some example embodiments, the first externally-observable feedback signal may include a green light, a vibration at a first frequency, an audio signal at a first frequency and/or volume, a sub-combination thereof, or a combination thereof. In some example embodiments, as shown in  FIG.  4 A , the difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  may be highlighted with a first highlighting  492  to provide a visual indication of the low difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430 . 
     At time t 12 , where instance I 12  of aerosol is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 12  of aerosol is determined, the projected cumulative amount  462 A of the aerosol that will be drawn through the sensor apparatus  100  upon completion of the presently ongoing instance I 12  of the aerosol may be determined to be greater than the corresponding threshold cumulative amount  462 B at time t 12  by difference D 12 . In response to such a determination, one or more feedback control signals may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate a second externally-observable feedback signal. In some example embodiments, the second externally-observable feedback signal may include a red light (the light could also be blue, green, yellow or any other color, sub-combinations or combinations thereof), a vibration at a second frequency, an audio signal at a second frequency and/or volume, a sub-combination thereof, or a combination thereof. In some example embodiments, as shown in  FIG.  4 A , the difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  may be highlighted with a second highlighting  494  to provide a visual indication of the high difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430 . 
     At time t 13 , where instance I 13  of aerosol is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 13  of aerosol is determined, the projected cumulative amount  463 A of the aerosol that will be drawn through the sensor apparatus  100  upon completion of the presently ongoing instance I 13  of the aerosol may be determined to be greater than the corresponding threshold cumulative amount  463 B at time t 13  by difference D 13 . In response to such a determination, one or more feedback control signals may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate the second externally-observable feedback signal. In some example embodiments, as shown in  FIG.  4 A , the difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  may be highlighted with a second highlighting  494  to provide a visual indication of the high difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430 . 
     At time t 14 , where instance I 14  of aerosol is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 14  of the aerosol is determined, the projected cumulative amount  464 A of the aerosol that will be drawn through the sensor apparatus  100  upon completion of the presently ongoing instance I 14  of the aerosol may be determined to be greater than the corresponding threshold cumulative amount  464 B at time t 14  by difference D 14 . In response to such a determination, one or more feedback control signals may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate the second externally-observable feedback signal. In some example embodiments, as shown in  FIG.  4 A , the difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  may be highlighted with a second highlighting  494  to provide a visual indication of the high difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430 . 
     At time t 15 , where instance I 15  of aerosol is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 15  of the aerosol is determined, the projected cumulative amount  465 A of the aerosol that will be drawn through the sensor apparatus  100  upon completion of the presently ongoing instance I 15  of the aerosol may be determined to be less than the corresponding threshold cumulative amount  465 B at time t 15  by difference D 15 . In response to such a determination, one or more feedback control signals may be generated to cause the feedback device  199  of the sensor apparatus  100  to generate the first externally-observable feedback signal. In some example embodiments, as shown in  FIG.  4 A , the difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430  may be highlighted with the first highlighting  492  to provide a visual indication of the low difference between the aerosol draw pattern  420  and the threshold aerosol draw pattern  430 . 
     As further shown in  FIG.  4 A , because instance I 15  of the aerosol is the final instance of aerosol drawn through the sensor apparatus  100  during time period t 0  to t 24 , the cumulative amount  465 A is equal to the total cumulative amount  421  that is drawn through the sensor apparatus  100  during the time period t 0  to t 24 . As further shown, based on the control of the feedback control signals generated to control a feedback device  199  and/or a displayed graphical representation  400 A, the total cumulative amount of the aerosol may be controlled by an ATC in response to the feedback control signals to be a total cumulative amount  421  that is less than the total threshold cumulative amount  431  for the same time period. 
     While the above description of  FIG.  4 A  describes the generation of feedback control signals in response to determinations of whether projected cumulative amounts of an aerosol to be drawn through a sensor apparatus  100  will exceed a corresponding threshold cumulative amount of the aerosol as indicated by the threshold aerosol draw pattern, it will be understood that, in some example embodiments, the generation of feedback control signals is in response to determined actual cumulative amounts of aerosol that have already been drawn through the sensor apparatus  100 , such that feedback control signals are generated based on historical amounts of aerosol that are drawn through the sensor apparatus  100  instead of projected amounts of aerosol that will be drawn through the sensor apparatus  100 . 
     Referring now to  FIG.  4 B , graphical representation  400 B illustrates the flow of an aerosol through the sensor apparatus  100  being controlled, via one or more feedback control signals generated according to at least the threshold aerosol draw pattern  430 , to cause the aerosol draw pattern  520  to conform to the threshold aerosol draw pattern  430 , such that the time-varying cumulative amount of an aerosol that is drawn through the sensor apparatus  100 , as indicated by the aerosol draw pattern  520  during a given time period t 0  to t 24  as shown in  FIG.  4 B  does not exceed the corresponding time-varying threshold cumulative amount of the aerosol as indicated by the threshold aerosol draw pattern  430  during the same given time period. 
     In some example embodiments, including the example embodiments shown in  FIG.  4 B , the aerosol draw pattern  520  indicates the time-variation of the cumulative amount of remainder generated aerosol  290  that is included in one or more instances I 21  to I 26  of drawn aerosol  230  that are drawn through the sensor apparatus  100 , but example embodiments are not limited thereto. As shown in  FIG.  4 B , graphical representation  400 B illustrates the effect of controlling the sensor apparatus  100  to control the amount and/or proportion of remainder generated aerosol  290  included in each separate instance I 21  to I 26  of drawn aerosol  230  that is drawn through the sensor apparatus  100  within a given time period t 0  to t 24 . 
     Still referring to  FIG.  4 B , the cumulative amounts of remainder generated aerosol  290  of both the aerosol draw pattern  520  and the threshold aerosol draw pattern  430  are set to a null value at the start of the time period t 0 . The threshold cumulative remainder generated aerosol  290  of the threshold aerosol draw pattern  430  increases over time during the time period from t 0  to t 24  according to a linear algorithm that defines the threshold aerosol draw pattern  430 , while cumulative remainder generated aerosol  290  of the aerosol draw pattern  520  increases in accordance with the amount of remainder generated aerosol  290  drawn through the sensor apparatus  100  in accordance with each successive instance I 21  to I 26  of drawn aerosol  230  that is drawn through the sensor apparatus  100  within a given time period t 0  to t 24  and at the respective times that the instances occur. 
     At time t 21 , where instance I 21  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 21  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 21  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  551 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 21  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  551 A may be determined to be less than the corresponding threshold cumulative amount  551 B at time t 21  by difference D 21 . Accordingly, the configuration of flow control device(s) of sensor apparatus  100  may not be adjusted in response to detection of instance I 21 , such that the projected cumulative remainder generated aerosol  290  amount  551 A is permitted to be drawn through sensor apparatus  100 . Additionally, as shown in  FIG.  4 B  with regard to instance I 21 , the representation of instance I 11  may be uniformly highlighted with a first highlighting, so as to illustrate that instance I 21  of drawn aerosol  230  comprises an instance of remainder generated aerosol  290  that is an entirety of the instances of generated aerosol  220  that is drawn through the sensor apparatus  100 . 
     At time t 22 , where instance I 22  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 22  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 22  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  552 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 22  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  552 A may be determined to be greater than the corresponding threshold cumulative amount  552 B at time t 22  by difference D 22 . Accordingly, the sensor apparatus  100  may be controlled, via one or more feedback control signals, to control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to adjust the projected amount of remainder generated aerosol  290  in the instance I 22  to not exceed the corresponding threshold cumulative amount  552 B. Such control may cause instance I 22  of drawn aerosol  230  to only comprise an instance of remainder generated aerosol  290  that may be a limited portion of the instances of generated aerosol  220  drawn through the sensor apparatus  100  during the ongoing instance of drawn aerosol  230 . Additionally, as shown in  FIG.  4 B  with regard to instance I 22 , the representation of instance I 22  may include separate portions  543 ,  544  having separate, first and second highlightings, where the first portion  544  is highlighted according to the first highlighting and the second portion  543  is highlighted according to the second highlighting, and where the first portion  544  has an area that is a proportion, of the total area of portions  543  and  544  of the given instance, that corresponds to a proportion of the remainder generated aerosol  290  in relation to the entirety of generated aerosol  220 . Thus, the differently-highlighted portion  544  provides a representation of the portion of generated aerosol  220  of instance I 22  which is restricted from being included in the drawn aerosol  230  of the given instance I 22  based on being directed from the sensor apparatus  100  as bypass aerosol  272 , thereby providing an illustration of the particular feedback control implemented on the sensor apparatus  100  in accordance with the threshold aerosol draw pattern  430  for each particular instance of drawn aerosol  230 . Accordingly, the graphical representation  400 B may provide an improved indication of the operation of the sensor apparatus  100  based on topography information generated based on sensor data generated at the sensor apparatus in order to provide improved control over the drawing of generated aerosol  220  through the sensor apparatus  100  to outlet opening  148  as at least a portion of drawn aerosol  230 . 
     At time t 23 , where instance I 23  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 23  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 23  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  553 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 23  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  552 A may be determined to be greater than the corresponding threshold cumulative amount  553 B at time t 23  by difference D 23 . Accordingly, the sensor apparatus  100  may be controlled, via one or more feedback control signals, to control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to adjust the projected amount of remainder generated aerosol  290  in the instance I 23  to not exceed the corresponding threshold cumulative amount  553 B. Such control may cause instance I 23  of drawn aerosol  230  to only comprise an instance of remainder generated aerosol  290  that may be a limited portion of the instance of generated aerosol  220  drawn through the sensor apparatus  100  during the ongoing instance of drawn aerosol  230 , and the representation of instance I 23  may include separate portions  543 ,  544  having separate, first and second highlightings. 
     At time t 24 , where instance I 14  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 24  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 24  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  554 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 23  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  554 A may be determined to be less than the corresponding threshold cumulative amount  554 B at time t 24  by difference D 24 . Accordingly, the configuration of flow control devices  292 ,  294 ,  296 ,  298  of sensor apparatus  100  are not adjusted in response to detection of instance I 24 , such that the projected cumulative remainder generated aerosol  290  amount  554 A is permitted to be drawn through sensor apparatus  100 . Additionally, as shown in  FIG.  4 B  with regard to instance I 24 , the representation of instance I 24  may be uniformly highlighted with a first highlighting, so as to illustrate that instance I 24  of drawn aerosol  230  comprises an instance of remainder generated aerosol  290  that is an entirety of the instance of generated aerosol  220  drawn through the sensor apparatus  100  during the ongoing instance of drawn aerosol  230 . 
     At time t 25 , where instance I 25  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 25  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 25  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  555 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 25  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  555 A may be determined to be greater than the corresponding threshold cumulative amount  555 B at time t 25  by difference D 25 . Accordingly, the sensor apparatus  100  may be controlled, via one or more feedback control signals, to control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to adjust the projected amount of remainder generated aerosol  290  in the instance I 25  to not exceed the corresponding threshold cumulative amount  555 B. Such control may cause instance I 25  of drawn aerosol  230  to only comprise an instance of remainder generated aerosol  290  that may be a limited portion of the instance of generated aerosol  220  drawn through the sensor apparatus  100  during the ongoing instance of drawn aerosol  230 , and the representation of instance I 25  may include separate portions  543 ,  544  having separate, first and second highlightings. 
     At time t 26 , where instance I 26  of drawn aerosol  230  is detected based on processing sensor data generated by pressure sensor devices  172 A,  172 B and an initial flow rate of the instance I 26  of drawn aerosol  230 , and a determined initial remainder generated aerosol  290  flow rate in the instance I 26  of drawn aerosol  230  is further determined based on the initial flow rate of the drawn aerosol  230  and a determined configuration of the one or more flow control devices  292 ,  294 ,  296 ,  298  of the sensor apparatus  100 , a projected cumulative remainder generated aerosol  290  amount  556 A that is projected to be drawn through the sensor apparatus  100  upon completion of the of the instance I 26  may be determined. As shown in  FIG.  4 B , the projected cumulative remainder generated aerosol  290  amount  555 A may be determined to be greater than the corresponding threshold cumulative amount  556 B at time t 26  by difference D 26 . Accordingly, the sensor apparatus  100  may be controlled, via one or more feedback control signals, to control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to adjust the projected amount of remainder generated aerosol  290  in the instance I 26  to not exceed the corresponding threshold cumulative amount  556 B. Such control may cause instance I 26  of drawn aerosol  230  to only comprise an instance of remainder generated aerosol  290  that may be a limited portion of the instance of generated aerosol  220  drawn through the sensor apparatus  100  during the ongoing instance of drawn aerosol  230 , and the representation of instance I 26  may include separate portions  543 ,  544  having separate, first and second highlightings. 
     As shown in  FIG.  4 B , based on the control of the amount of remainder generated aerosol  290  included in the instances of drawn aerosol  230  during the time period, the total cumulative amount  521  of remainder generated aerosol  290  during the time period is a threshold cumulative amount  556 B that is less than the total threshold amount  431  for the same time period. 
     Accordingly, as shown in at least  FIG.  4 B , a sensor apparatus  100  may be configured to adjustably control one or more flow control devices  292 ,  294 ,  296 ,  298  thereof to cause the time-varying cumulative amount of remainder generated aerosol  290  included in instances of drawn aerosol  230  in a given time period to not exceed the time-varying maximum amount of remainder generated aerosol  290  as defined by the threshold aerosol draw pattern  430  such that the flow of the remainder generated aerosol  290  is caused to conform to the threshold aerosol draw pattern  430 . 
     It will be understood that, in some example embodiments, a threshold aerosol draw pattern, such as the threshold aerosol draw pattern  430 , may be a stored threshold aerosol draw pattern that may be accessed from a storage device and compared with an aerosol draw pattern, such as the aerosol draw pattern  420  as shown in  FIG.  4 A  and/or the aerosol draw pattern  520  as shown in  FIG.  4 B . In some example embodiments, the threshold aerosol draw pattern may be a particular threshold aerosol draw pattern that may be selected and/or predetermined and compared with an aerosol draw pattern, such as the aerosol draw pattern  420  as shown in  FIG.  4 A  and/or the aerosol draw pattern  520  as shown in  FIG.  4 B . 
     It will be understood that, in some example embodiments, a threshold cumulative amount of the portion of the generated aerosol drawn through the conduit over the period of time, such as the threshold cumulative remainder generated aerosol  290 , may be a stored value and/or algorithmic representation that may be accessed from a storage device and compared with an aerosol draw pattern, such as the aerosol draw pattern  420  as shown in  FIG.  4 A  and/or the aerosol draw pattern  520  as shown in  FIG.  4 B . In some example embodiments, the a threshold cumulative amount of the portion of the generated aerosol drawn through the conduit over the period of time may be a particular value and/or algorithmic representation that may be selected and/or predetermined and compared with an aerosol draw pattern, such as the aerosol draw pattern  420  as shown in  FIG.  4 A  and/or the aerosol draw pattern  520  as shown in  FIG.  4 B . 
     It will be understood that in some example embodiments controlling a flow of a given aerosol may include controlling a flow rate of the given aerosol through one or more portions of the conduit  129  at one or more times during a time period, controlling an amount of the given aerosol that is drawn through one or more portions of the conduit  129  at one or more times during a time period, a sub-combination thereof, or a combination thereof.
