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'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.

In some example embodiments, the interface device 184 be a communication interface for the sensor apparatus 100 and may be configured to enable information to be communicated between the sensor apparatus 100 and an external device via a communication link. In some example embodiments, the interface 184 is a communication interface that is a wireless network communication interface that is configured to enable information to be communicated between the sensor apparatus 100 and an external device via a communication link that is a wireless network communication link. 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 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.

It will be understood that, in some example embodiments, the conduits 188A, 188B may be established by multiple structures that are coupled to the conduit structure 120 to enclose the pressure sensor devices 172A, 172B.
In some example embodiments, the temperature sensor device 179 that is configured to measure a temperature at conduit portion 129A. It will be understood, however, that in some example embodiments the temperature sensor devices 179 may measure a temperature at conduit portion 129B and/or conduit portion 129A. 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.

In some example embodiments, the pressure sensor device 172A may be configured to generate sensor data that, when processed, provides an indication of the pressure of aerosol 240 in the first conduit portion 129A of the conduit 129, and the sensor device 172B may be configured to generate sensor data that, when processed, provides an indication of the pressure of aerosol 260 in the second conduit portion 129B 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 172A, 172B. 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 172A, 172B 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 “ρt” is a density of the aerosol 240 in the conduit portion 129A.
Assuming that the values of “C”, “β”, “ε”, “ρt”, and “d” are constant values, the flow rate Q may be calculated based on the pressure differential “ΔP” and a calculated constant value “K” that is derived from one or more of “C”, “β”, “ε”, “βt”, and “d” as shown in equation (2) below:
It will be understood that the values of “C”, “β”, “ε”, “μ1”, and “d” may be determined through well-known, empirical methods. In some example embodiments, the values of “C”, “β”, “ε”, “ρ1”, 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 172A, 172B 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 172A, 172B.
In some example embodiments, the sensor apparatus 100 may generate information based on the sensor data generated by the pressure sensor devices 172A, 172B, 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 172A, 172B, 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 172A, 172B 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 172A, 172B, a magnitude of a pressure differential between the separate pressures measured by the separate pressure sensor devices 172A, 172B 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 172A, 172B, 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 172A, 172B 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.

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 172A, 172B 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.

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 172A, 172B 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.

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 172A, 172B 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
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 172A, 172B 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.

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
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
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 172A, 172B, 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 172A, 172B, 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
In some example embodiments, an assembly 300, including a sensor apparatus 100 and an external tobacco element 200 as shown in
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=ax2+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.
Referring first to
At S504, 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 S504, 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 S502.
At S505, 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 S506, a threshold aerosol draw pattern is determined, based at least in part upon the aerosol draw pattern that is determined at S504 and/or the threshold aerosol properties received, selected, and/or determined at S505. 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 S508, 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 S504 exceeds or conforms to the threshold aerosol draw pattern that is determined at S506. As described below with reference to
At S509, 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
In some example embodiments, operation S508 may be omitted and topography information may be displayed, at S509, without any control of any portion of the sensor apparatus 100 via one or more feedback control signals. In some example embodiments, operations S505 and S506 may be omitted in addition to operation S508 being omitted, and the topography information displayed at S509 may omit any display of information associated with any threshold aerosol draw pattern.
Referring now to
At S510, 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 S504, a projected aerosol draw pattern may be generated based on the historical aerosol draw pattern and information, received at S502, 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 S516, 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 S516, as shown at S522, S524, 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 S522 and S524 may be omitted.
In one example, if the determined aerosol draw pattern conforms to the threshold aerosol draw pattern at S516, at S522 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 S516, at S524 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 S516, at S522 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 S516, at S524 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 S524, 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 S524, 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.

Graphical representation 400A may be updated over time to include new representations of instances I1 to IN 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 400A 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 400A 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 400A 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 t0-t24.
