Description

[Technical Field]

[0001] This application claims priority to U.S. Patent Application No. 15 / 892,151, filed February 8, 2018, and U.S. Patent Application No. 15 / 710,681, filed September 20, 2017, the contents of which are incorporated herein by reference in their entireties.

[0002] The present invention relates to aerosol delivery articles and their use for obtaining tobacco components or other materials in an inhalable form. The articles may be made from, derived from, or otherwise incorporate tobacco for human consumption. More specifically, the present invention relates generally to the field of electronic or powered smoking articles. [Background technology]

[0003] Many smoking devices have been proposed over the years as an improvement or replacement for smoking products that require the burning of tobacco for use. Many of these devices are designed to provide the sensation associated with smoking a cigarette, cigar, or pipe, but are said to do so without delivering the significant amounts of incomplete combustion and pyrolysis products resulting from the burning of tobacco. To this end, many smoking products, flavor generators, and medicinal inhalers (e.g., "heat-not-burn" products) have been proposed that utilize electrical energy to vaporize or heat volatile materials or attempt to provide the sensation of smoking a cigarette, cigar, or pipe without significantly burning tobacco. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat sources described in the background art of U.S. Patent Application Publication No. 2013 / 0255702 to Griffith Jr. et al., U.S. Patent Application Publication No. 2014 / 0000638 to Sebastian et al., U.S. Patent No. 5,060,671 to Counts et al., U.S. Patent No. 9,016,274 to White, U.S. Patent No. 9,078,474 to Thompson, U.S. Patent Application Publication No. 2014 / 0060554 to Collett et al., U.S. Patent Application Publication No. 2014 / 0096781 to Sears et al., U.S. Patent Application Publication No. 2014 / 0096782 to Ampolini et al., and U.S. Patent Application Publication No. 2015 / 0059780 to Davis et al., the entireties of which are incorporated herein by reference.

[0004] Typical electronic smoking articles or powered smoking articles (e.g., electronic cigarettes, e-cigarettes, etc.) (collectively referred to herein as "electronic smoking articles") often include a liquid storage component for storing aerosol precursor material (e.g., aerosol formers, liquid smoke, etc.), a vaporization chamber having a heating coil attached thereto for vaporizing the aerosol precursor material, and a battery for powering the device. The aerosol precursor material typically includes a mixture of propylene glycol, glycerin, nicotine, water, and flavorings. Various electronic smoking articles have a single device, commonly referred to as a cartomizer, that houses both the heating element and the aerosol precursor material in one unit.

[0005] Certain tobacco products that use electrical energy to generate heat for smoke or aerosol formation, particularly those referred to as e-cigarette products or electronic smoking articles, are commercially available worldwide. Representative products that mimic many of the attributes of a traditional cigarette, cigar or pipe include ACCORD® by Philip Morris Incorporated, ALPHA™, JOYE 510™ and M4™ by InnoVapor LLC, CIRRUS™ and FLING™ by White Cloud Cigarettes, COHITA™, COLIBRI™, ELITE CLASSIC™, MAGNUM™, PHANTOM™ and SENSE™ by Eupuffer® International Inc., DUOPRO™, STORM™ and VAPORKING® by Electronic Cigarettes, Inc., EGAR™ by Egar Australia, eGo-C™ and eGo-T™ by Joyetech, ELUSION™ by Elusion UK Ltd, EONSMOKE® by Eonsmoke LLC, and GREEN by Green Smoke Inc.

In some of these electronic smoking articles, when a user inhales on the electronic smoking article, gravity and capillary forces within the wick "pull" the aerosol precursor material from a reservoir into a vaporization chamber. The aerosol precursor material is adsorbed onto or rests on the vaporizer's heating device and heated until it becomes a vapor. The vapor is drawn away from the heated region of the device, then cooled and condensed into a dense aerosol, generally submicron, which then exits the device. The wick material can include any combination of silica, organic cotton, cellulosic rayon fiber, stainless steel, fiberglass, ceramic, and other materials with similar properties.

[0007] Currently, options for recording and understanding how individuals use electronic smoking articles are limited. For example, in clinical trials, most attempts have tested adapting technologies used to measure combustible cigarette use (e.g., topography), using video recordings of people using electronic smoking articles, or questioning individual users to recall how they used their electronic smoking articles. These methods are limited by confining the individual users being monitored to a single location. Thus, recording and documentation of usage occurs in "unrealistic" situations. In other words, measuring usage undermines how people use electronic smoking articles by restricting individuals to specific test locations rather than under normal, everyday locations and usage. Furthermore, what "traditional" (e.g., under current monitoring methods) topography actually measures does not directly relate to what happens when people use electronic smoking articles. Traditional topography with electronic smoking articles focuses on the air volume and pressure generated during a puff. The device is built around a pressure transducer and an analog-to-digital converter that convert the pressure dynamics of a puff to collect and calculate puff-by-puff and cigarette-by-cigarette summaries of puff characteristics. The topography device is positioned between the electronic smoking article and the user. This placement alters the way the user uses the product compared to how the user would naturally use the product. This interference may alter the way the user uses the product during testing and may not provide information that accurately represents how the user consumes the actual product. Furthermore, using traditional topography requires the consumer / subject to sit tethered to the traditional topography device in a laboratory environment, further influencing product use and behavior. Therefore, it would be desirable to provide a device that can be retrofitted to various electronic smoking articles and that can monitor and capture individual user usage and electronic smoking article usage under normal conditions (e.g., everyday personal use without monitoring).

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all aspects of the disclosure are shown. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the aspects set forth herein. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art, and will satisfy applicable legal requirements. Like numbers refer to like elements throughout. As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

[0018] A product use and behavior ("PUB") device is described generally with reference to the drawings. The PUB device is structured to record various aspects of electronic smoking article use, including how a user uses the electronic smoking article and how the electronic smoking article responds to that use. The PUB device may also be adapted to monitor tobacco heating system ("THS") electronic smoking articles, which utilize a "heat-and-serve" configuration that heats tobacco to a lower temperature than when a conventional smoking article is combusted, or heats tobacco in a manner different from heating a liquid as in conventional electronic smoking articles. As will be appreciated, PUB devices and PUB-THS devices are similar in the data collected and general configuration, such that features described in connection with PUB devices may also be implemented by PUB-THS devices, and vice versa. Therefore, unless otherwise specified, embodiments and disclosures referenced in connection with PUB devices may also apply to PUB-THS devices, and vice versa. Thus, reference to PUB equipment includes both PUB equipment and PUB-THS equipment.

[0019] As used herein, heating of an inhalable substance includes electronic smoking articles that vaporize a liquid, electronic smoking articles that use a heating element to heat porous substrate tobacco, electronic smoking articles that utilize precursor components in a tobacco substrate, electronic smoking articles that use a precursor that is heated to form an aerosol that passes through the porous tobacco substrate, medical devices that can heat a liquid and / or solid form of a drug to form an aerosol (the drug can be heated using any of the device configurations described herein), and any combination thereof. In configurations that utilize porous substrate tobacco, the porous tobacco substrate may include a packed bed of particles of a wide variety of shapes, such as ground, pulverized, or powdered tobacco flakes, a tobacco monolith containing air passages, stacked (or bundled) layers of tobacco sheet, and / or other forms of tobacco and / or reconstituted tobacco. Exemplary configurations using a tobacco substrate heated by an aerosolized liquid, to which various embodiments may be applied, include the background art cited in U.S. Patent Application Publication Nos. 2015 / 0335070 and 2017 / 0065000, which are incorporated herein by reference in their entireties. In some configurations utilizing a precursor, the porous tobacco substrate is heated by the passing aerosol but not directly by the heating element. The precursor may or may not contain nicotine and / or other tobacco derivatives. Additionally, any of the described electronic smoking articles may be configured in a "dual heating" configuration. In these configurations, the electronic smoking article includes a vapor precursor (e.g., liquid) heated by a first heating element and a porous tobacco substrate downstream of the precursor heated by a second heating element. As will be understood, the heated vapor passes through / over the heated porous tobacco substrate. As a result, the porous tobacco substrate (e.g., shreds, spheres, granules, etc.) is heated by the second heating element and by the vapor passing through / over it. Additionally, the aerosol precursor may be realized in either or both the packing layer of the tobacco chamber and the atomization chamber. Furthermore, the electronic smoking articles described above may be configured with dual and / or multiple heating elements.

[0020] In some embodiments, extending the configurations utilizing precursor components in the tobacco substrate, a combustible heat source, such as a carbon heat source, may be used in addition to or instead of an electric heater. The combustible heat source may be positioned at the front (e.g., non-mouth) end of the product to provide heat to the downstream tobacco packing layer. In these configurations, air is drawn through the combustible heat source, heated, and transported through the tobacco layer containing the aerosol precursor. The hot air heats the tobacco and precursor material, vaporizing the precursor, which interacts with the tobacco substrate to produce a vapor that then condenses to form the aerosol. Exemplary configurations using a carbonaceous heat source, to which various embodiments may be applied, include the Premier™ and Eclipse™ electronic smoking articles by RJ Reynolds Tobacco Company, and the configurations described in "Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, RJ Reynolds Tobacco Company Monograph" (1988). Further exemplary configurations using combustible fuel sources to which various embodiments may be applied include the background art cited in U.S. Pat. No. 4,714,082 to Banerjee et al. and U.S. Pat. No. 4,771,795 to White et al., which are incorporated herein by reference in their entireties.Also, for example, U.S. Pat.

[0021] As used herein, heating a tobacco product includes the use of heat in conjunction with tobacco or a tobacco substrate, such as, for example, electronic smoking articles that use a heating element to heat porous substrate tobacco, electronic smoking articles that utilize precursor components in a tobacco substrate, and electronic smoking articles that use a precursor that is heated to form an aerosol that passes through the porous tobacco substrate, as described above. As will be appreciated, either the PUB device or the PUB-THS device may be configured to engage, monitor, and record a wide variety of electronic smoking articles that heat inhalable substances, including, for example, medical devices that heat inhalable drugs.

[0022] Generally, PUB devices can record and detect the battery activation of an electronic smoking article, battery characteristics (e.g., wattage, voltage, and resistance), position (e.g., global position), device orientation, device movement, the temperature of the airflow entering the electronic smoking article, and the sound of the airflow entering the electronic smoking article. With respect to user usage, PUB devices can measure usage characteristics, patterns from moment to moment and over a period of time (e.g., hourly, daily, weekly), puff behavior (e.g., number, duration, volume, inter-puff interval, etc.), and changes in characteristics over time or over a period of use (e.g., smoking and non-smoking behavior using the PUB device). Beneficially, any PUB device is structured to be retrofitted to various electronic smoking articles so as to be compatible with a wide variety of battery tanks, battery cigarette sticks, or battery cartridge connections for electronic smoking articles. As used herein, the term "tank" refers to some or all of the aerosol-generating elements of an electronic smoking article, including cartridges, cartomizers, wicks, atomizers, heating elements, substrates, reservoirs, and similar elements. As used herein, the term "tobacco stick" refers to part or all of an aerosol-generating element that contains tobacco in some form. Tobacco forms may include, for example, tobacco impregnated with a mixture of tobacco and other elements, loose-leaf tobacco vaporizers that involve placing loose-leaf tobacco in a chamber that is electrically heated using an element, or similar elements. In some embodiments, electronic smoking articles are heatless delivery systems that utilize mechanical atomization.

[0023] Generally, the PUB device includes an array of sensors for recording product usage characteristics, onboard memory for storing collected data, an onboard rechargeable power source, a wireless (e.g., Bluetooth™) communication array for transferring data to an external storage location, a first connector for the tank end, and a second connector for the battery end. Once the PUB device is installed in an electronic smoking article, data monitoring and collection can be triggered or continued by activating and deactivating the electronic smoking article. Once partial data acquisition is complete, the PUB device may synchronize with a wireless communication-compatible computing device (e.g., desktop, laptop, tablet, smartphone, etc.) and upload the data to a secure database. The data may be exportable to any statistical software package for subsequent analysis or to task-specific summarization software. As will be appreciated, the PUB device may be utilized to capture and track electronic smoking article usage data for behavioral modeling, track usage, and provide information on usage patterns in clinical and non-clinical studies.

[0024] Unlike traditional clinical techniques (e.g., topography), the PUB device does not primarily use air movement to generate values ​​related to puff dynamics due to the nature of the differences between combustible smoking articles and electronic smoking articles. Furthermore, the PUB device does not obstruct the path between the user (or clinical trial subject) and the product, preventing the product's proper function and the user's experience while using the electronic smoking article. Finally, the PUB device is fully portable, allowing users to use electronic smoking articles in a clinic, laboratory, or outpatient (outside of a clinic or laboratory) environment. This increases the likelihood that the device's recordings will match the actual usage characteristics of the electronic smoking article.

[0025] Referring to FIG. 1 , a perspective view of an unassembled PUB device 100 is shown according to an exemplary embodiment. The PUB device 100 includes a control device 102 and a housing 104. In a specific embodiment, the housing 104 includes a first outer shroud and a second outer shroud. The PUB device 100 monitors, records, and transmits a plurality of user usage data and electronic smoking article device data. The PUB device 100 is structured to have a form, size, and connector that allows it to be adapted to interface with a wide variety of electronic smoking articles (e.g., e-cigarettes, pens, open and / or closed system “tank” product designs) without interfering with their operation. As will be appreciated, the PUB device 100 is durable and can be used in both controlled and restricted environments, both with and without supervision, in accordance with product safety standards for mobile laboratory equipment.

[0026] The controller 102 includes a first end connector 110, a second end connector 112, a sensor array 116, a PUB battery 118, an onboard memory 120, and an antenna 122. The controller 102 is structured to monitor, record, and store multiple data and characteristics of the user and the electronic smoking article. The controller 102 is structured to interface with a wide variety of electronic smoking articles and to have a size and connector that physically interferes as little as possible with the electronic smoking article's intended configuration. The controller 102 acquires real-time data related to characteristics of individual puff behavior (e.g., number, duration, volume, inter-puff interval), changes in puff characteristics from time to time, changes in puff characteristics over a time interval, and similar information. For example, captured puff characteristics may include, but are not limited to, puff volume (ml), puff duration (s), number of puffs, number of sub-puffs, average and peak flow rate (ml / s), average and peak draft (ml / s), average and peak resistance, average and peak pressure drop (mmWg), inter-puff interval (s), and light duration (s). The controller 102 may also record battery characteristics (e.g., wattage, voltage, and resistance), location, device orientation, device movement, temperature of the airflow entering the electronic smoking article, and sound of the airflow entering the electronic smoking article. The controller 102 facilitates storage of data characteristics related to moment-to-moment user usage behavior and usage patterns over a period of product interaction (e.g., hourly, daily, weekly). The controller 102 and associated elements may be physically implemented on a circuit board.

[0027] The first end connector 110 includes a coupling element configured to removably couple to and interface with the battery end of an electronic smoking article. Electronic smoking articles can be in a variety of different "configurations," such as box-style, pen-style, or open-system "tank"-style product designs. Each type of electronic smoking article can have a variety of coupling mechanisms for attaching the battery to the tank. In some embodiments, more than one PUB device 100 (e.g., modules) may be used with a single electronic smoking article. In those embodiments, the first end connector 110 may be structured to couple with another modular PUB device 100. As will be appreciated, the size and type of coupling element of the first end connector 110 will depend on the components within the particular electronic smoking article. Exemplary connections are described in further detail below with reference to FIGS. 2A-4C.

[0028] The second end connector 112 includes a coupling element structured to removably couple to and interface with the tank (e.g., smoking material reservoir) end of an electronic smoking article. Electronic smoking articles can be in a variety of different "configurations," such as e-cigarettes, pens, and open-system "tank" product designs. Each type of electronic smoking article can have a variety of coupling mechanisms for attaching a rechargeable battery to the tank. In some embodiments, one or more PUB devices 100 (e.g., modules) may be used with a single electronic smoking article. In those embodiments, the second end connector 112 may be structured to couple with another PUB device 100. As will be appreciated, the size and type of coupling element of the second end connector 112 will depend on the components that make up the interior of the particular electronic smoking article. The different connections are described in further detail below with reference to FIGS. 2A-4C.

[0029] The on-board memory 120 is structured to store the data and characteristics collected by the sensor array 116. The on-board memory 120 may be, for example, flash memory or electrically erasable programmable read-only memory (“EEPROM”) memory. The on-board memory 120 should provide sufficient memory capacity to allow storage of the highest estimated data load generated over a set period of time, for example, seven days. In some embodiments, the on-board memory 120 may be reset to a null value, and the on-board clock may be resynchronized once the data is uploaded. In other embodiments, the on-board memory 120 is structured to retain all data until the on-board memory 120 reaches capacity. The on-board memory 120 stores the data in raw data format, date and time stamped, and may be used to determine a wattage value. As will be appreciated, the wattage value combined with the puff duration value may be used to generate a total particulate matter (“TPM”) constant for the estimated mouth-level exposure (“eMLE”) of the aerosol measurement. Data captured by the sensor array 116 is stored in the on-board memory 120, both as individual, individual data points and as part of a cumulative, time-stamped record.

[0030] The PUB battery 118 includes an on-board rechargeable battery. The PUB battery 118 may also be a rechargeable solid-state battery. The PUB battery 118 powers the PUB device 100 and is structured to ensure that the performance of data collection by the PUB device 100 is not affected by the battery's performance. The PUB battery 118 should be able to maintain a charge through the subject's highest estimated level of use. In some embodiments, the PUB battery 118 lasts for at least seven days without needing to be recharged. In some embodiments, the PUB battery 118 is recharged when the electronic smoking article's battery is recharged. In other embodiments, the PUB device 100 includes a charging port on the housing 104 that can charge the PUB battery 118. In some embodiments, the PUB device 100 does not have a PUB battery 118. Instead, the PUB device 100 draws power from the electronic smoking article's battery.

[0031] The antenna 122 is configured to transmit data collected by the sensor array 116 and stored by the onboard memory 120. The antenna 122 may be configured to upload data during the electronic smoking article's charging cycle, during activation of the electronic smoking article device, continuously throughout the electronic smoking article's lifecycle, or during a similar trigger event. In some embodiments, the onboard memory 120 may be reset to a null value, and the onboard clock may be resynchronized upon completion of data upload by the antenna 122. In some embodiments, the PUB device 100 uses Bluetooth™ or other wireless communication technology to facilitate the transfer of data from the PUB device's 100 memory to a secure location (e.g., a server location) via data transfer software (e.g., PC, iOS™, or Android™). The antenna 122 is designed to minimize interference with the aerosol generated by wireless transmission of data via Bluetooth™. In other embodiments, the antenna 122 has a wired interface that allows for a wired connection to the secure location via data transfer software. The security and integrity of the data during its transit from the antenna 122 of the PUB appliance 100 to the computer or smart device to the database server may be maintained in accordance with appropriate research data standards. In some embodiments, the data hosted in the secure database may be used to communicate with PCs and / or smart devices (e.g., smartphones and / or tablets) to present additional information to the user of the PUB appliance 100.

[0032] The sensor array 116 is configured to monitor and record one or more data characteristics of the electronic smoking article and user usage data. The sensor array 116 is configured to monitor and record a wide variety of user usage characteristics and data. The sensor array 116 can capture real-time data related to individual usage behavior characteristics (e.g., puff count, duration, capacity, inter-puff interval), how these characteristics change from time to time, and how battery characteristics such as power (e.g., wattage) change from time to time. The sensor array 116 may measure the time between the end of a puff (e.g., battery shutdown) and the start of the next puff (e.g., battery activation), also known as the inter-puff interval (“IPI”). As will be appreciated, puff statistics captured by the sensor array 116 can be used to capture puff, rapid puff, and sub-puff counts and duration values, as well as IPI counts and duration values. In some embodiments, the sensor array 116 monitors and captures battery activation that coincides with the start of a puff and measures the time the battery is activated to determine the puff duration, while in other embodiments the sensor array 116 may record the end of a puff when the battery is no longer activated.

[0033] With respect to electronic smoking articles, the sensor array 116 may include specific sensors for detecting the electronic smoking article's battery activation, battery characteristics (e.g., wattage, voltage, current, and resistance), or battery age (e.g., length of smoking time). As will be appreciated, data captured by the sensor array 116 is stored in the on-board memory 120, both as individual data points and as part of a cumulative, time-stamped record.

[0034] In some embodiments, the sensor array 116 includes hardware sensors that track the position of the electronic smoking article during use. For example, a nine-axis gyroscope is used to capture the orientation of the PUB device 100, an accelerometer is used to capture the movement of the PUB device 100, and a global position system ("GPS") or other satellite navigation system (e.g., Galileo, GLONASS, BeiDou, etc.) is used to capture the location of the PUB device 100. In such embodiments, a position tracking device can be used to generate data regarding the position of the electronic smoking article in relation to the positional relationship between the battery end and the tank end of the electronic smoking article. Advantageously, recording this positional relationship allows researchers to determine how a user held the electronic smoking article while performing a puff. Determining whether a user smoked the electronic smoking article while lying on a couch with the battery above the tank, compared to whether the user held the electronic smoking article while sitting in a manner similar to a traditional cigarette, can provide more information regarding the normal use of the electronic smoking article and provide details regarding tank leaks and malfunctions / failures of the electronic smoking article product.

[0035] The sensor array 116 may include a hardware sensor that detects changes in ambient temperature within the airway port of the electronic smoking article. Temperature changes may be used to distinguish between the initiation of a puff and continued use of the electronic smoking article. In some embodiments, the PUB device 100 may include a hardware sensor that detects the speed at which the PUB device 100 moves from one position to another. In these embodiments, the linear acceleration of the PUB device 100 is measured with respect to use / non-use to identify the start of a period of product use. In other embodiments, the PUB device 100 may include a hardware sensor that records the sound frequency of air passing through the dedicated airway port of the PUB device 100. In such embodiments, passive acoustic measurements may be used to provide information for understanding puff speed and the general shape of individual puff characteristics.

[0036] The PUB device 100 may also include hardware sensors that track and record events measured by other components that make up the PUB device 100. Advantageously, this tracking is time-stamped so that every recorded event forms a cumulative record. The cumulative record can be tracked and exported to any statistical software package or task-specific summarization software for subsequent analysis. In other embodiments, the PUB device 100 may receive externally processed cumulative records via download to the PUB device 100. In such embodiments, the PUB device 100 may perform additional analysis or task-specific summarization of the externally processed data. In other embodiments, the PUB device 100 performs information and feedback analysis of the cumulative records within the device. In other embodiments, the PUB device 100 may include a photo sensor, mechanical sensor, and / or pressure sensor that detects whether the PUB device 100 has been removed from the battery and / or tank end of the electronic smoking article.

[0037] In some embodiments, the PUB device 100 includes a toggle function on the control device 102. The toggle function can turn on, off, limit, or change one or more data characteristics monitored and recorded by the PUB device 100. For example, the toggle function may limit the total number of puffs (e.g., in terms of duration, number, or a combination of both) generated over a certain period of time (e.g., minutes / hours / days / weeks, etc.) to limit the number of uses of the electronic smoking article. In other embodiments, the PUB device 100 includes a single activation button that can be used to trigger or mark an event (e.g., date / time / location) that occurs during the use of the electronic smoking article. In some embodiments, the PUB device 100 includes a screen (e.g., LCD, LED, OLED, or other suitable screen) inserted into the housing 104. The screen displays the status of any of the events recorded or managed by the PUB device 100. The screen may also facilitate a user's adjustment of the data monitored and recorded by the sensor array, for example, via a toggle function. The user may use the screen to select an "off" option for one or more characteristics of data to be collected, for example, the user's location while using the PUB appliance 100.

[0038] The PUB device 100 may also include an identifier associated with the structure and characteristics of the PUB device 100. The identifier is updatable for each user while the PUB device 100 is in use. As will be appreciated, this may allow a user to switch between clinical (e.g., data captured for third-party analysis) and non-clinical (e.g., data captured for the user's analysis) testing. The identifier may be incorporated into the data set to allow matching of data type (e.g., clinical, non-clinical, specific user, type of PUB device 100) and data source. Additionally, the identifier may be encoded into the PUB device 100, visually apparent through an embossed portion of the housing 104 of the PUB device 100, or affixed by a label to the housing 104 of the PUB device 100. In some embodiments, the sensor array 116 may include access control via a biometric security sensor, such as, for example, a fingerprint sensor for detecting fingerprint characteristics. In those embodiments, use of the electronic smoking article and / or data characteristic collection may occur only if the fingerprint sensor captures a fingerprint from an authorized user (e.g., associated with the PUB device). As will be appreciated, biometric security sensors may be configured to capture a wide variety of biometric data from authorized users (eg, iris, voice, gait, etc.).

[0039] In certain embodiments, the PUB device 100 is configured as a series of modules. A single-module PUB device 100 may be positioned between the battery end and the tank end of an electronic smoking article. A single-module PUB device 100 may be structured to monitor and record single or multiple data or characteristics. Multiple modular PUB devices 100 may be connected along an electronic smoking article to monitor and record single or multiple data or characteristics. As will be appreciated, modular PUB devices 100 may tailor an electronic smoking article to capture a specific subset of data and characteristics. For example, a user may want to utilize a PUB device 100 to capture data characteristics but not allow location data to be transmitted or captured. Thus, a user's electronic smoking article may include a modular PUB device 100 that monitors and records data or characteristics unrelated to location. In some embodiments, the PUB device 100 includes a chip configured to interface with the electronic smoking article and collect at least one usage data characteristic.

[0040] As will be appreciated, the data collected by the sensor array 116 can be input into a graphics-based software program for summarization and pattern recognition of electronic smoking article use over a specific period of time. The software may import raw data exported from the database on a per-user / per-trial basis. The data may be processed to summarize and apply algorithms to calculate individual product use factors, product use rates and / or patterns, and eMLE of aerosol measurements. Within the software program, information associated with the specific electronic smoking article under evaluation (e.g., TPM data values) necessary to perform the analysis can be modified. The data generated by this process may be uploaded to the PUB device 100 database. As will be appreciated, the imported data and exported results meet data security and integrity standards. In other embodiments, the data collected by the sensor array 116 is sent to task-specific summarization software.

[0041] Referring to FIG. 2A , a perspective view of an assembled electronic smoking article 202 is shown according to an exemplary embodiment. The electronic smoking article 202 includes a battery 204 and a cylindrical reservoir 206 that contains liquid or other smoking material. The battery 204 is removably coupled to the reservoir 206 via complementary torsional (e.g., twisted) interfaces on the ends of the battery 204 and the reservoir 206. As will be appreciated, a user of the electronic smoking article 202 can unscrew the battery 204 from the reservoir 206 for maintenance purposes to replace any components, charge the battery 204, or perform similar operations. In some embodiments, the electronic smoking article 202 has a light-emitting diode ("LED") indicator end on the battery 204. The LED indicator end mimics the lit end of a traditional cigarette and indicates when the electronic smoking article is activated. The mouth-end of the reservoir 206 allows a user to blow into or draw on the electronic smoking article 202, drawing air through the battery 204 and into (e.g., indirect) contact with the liquid in the reservoir 206, ultimately bringing the mouth-end into contact with the user. In other embodiments, air is drawn into a heating or vaporization chamber and flows over / around a heated wick containing liquid from the reservoir 206. The air picks up heated vapor from the wick, condenses into an aerosol, and the aerosol flows to the mouth-end. In one embodiment, inhalation to draw in air initiates the vaporization process. Alternatively, activation of a circuit closure (mechanical or optical) initiates the vaporization process.

[0042] In contrast to traditional cigarettes, the product produced by an electronic smoking article 202 is not smoke, but an aerosol or vapor resulting from the volatilization or vaporization of certain components incorporated therein. Inhalable matter can be found in both the particle and vapor fractions of the aerosol. Vapor is defined as a substance in the gas phase at a temperature below its critical point. In electronic smoking articles, particulate matter consists of vapor condensed into small droplets. Both particles and vapor are suspended in the gases (primarily oxygen and nitrogen) that make up the entrained air. For clarity, the term "vaporized liquid" as used herein is meant to include vapors, gases, and particles, i.e., aerosols, in any form or type suitable for human inhalation, whether or not they are visible and in a form that can be considered smoke-like.

[0043] The reservoir 206 contains the liquid to be vaporized and delivered to the user. In some embodiments, the liquid includes substances such as, for example, nicotine, propylene glycol, glycerin, water, flavorings, or other suitable materials that can be used to be vaporized. In certain embodiments, the liquid is a combination of nicotine, propylene glycol, and glycerin. Additionally, volatile organic compounds (VOCs) or tobacco alkaloids may be produced during the heating process. The reservoir is not limited to a particular size and may be opaque or transparent so that the user can see the liquid therein.

[0044] FIG. 2B shows a perspective view of an unassembled PUB device 100 and the electronic smoking article of FIG. 2A according to an exemplary embodiment. As shown in FIG. 2B, the PUB device 100 includes a first end connector 210 configured for torsional interfacing with the battery 204 end of the electronic smoking article 202. The PUB device further includes a second end connector 212 configured for torsional (e.g., twisting) interfacing with the reservoir 206 end of the electronic smoking article 202. As will be appreciated, the PUB device 100 may include one or more of the components described above and the sensor array 116. While only one PUB device 100 is shown in FIG. 2B, in some embodiments, more than one PUB device 100 (e.g., modules) may be used with the electronic smoking article 202. In those embodiments, the first end connector 210, the second end connector 212, or both, may be structured to couple with another PUB device 100. In some embodiments, the housing 104 of the PUB device 100 is modified to better fit the configuration of the electronic smoking article 202. As will be appreciated, the size and type of coupling element of the first end connector 110 will depend on the components that make up the interior of the electronic smoking article 202.

[0045] Referring to Figure 2C, a perspective view of the PUB device 100 of Figure 2B assembled with an electronic smoking article 202 (a combination referred to herein as a "PUB delivery system" 200) is shown, according to an exemplary embodiment. The PUB delivery system 200 has the same general form and structure as the original electronic smoking article 202. The PUB device 100 has a size and form structured to minimize physical interference with the intended form of the electronic smoking article 202. The components of the PUB device 100 ensure that the performance and use of the PUB delivery system 200 is substantially similar to the performance and use of the electronic smoking article 202.

[0046] Referring to FIG. 3A , a perspective view of an assembled electronic smoking article 302 according to an exemplary embodiment is shown. The electronic smoking article 302 is similar to the electronic smoking article 202. The difference between the electronic smoking article 302 and the electronic smoking article 202 is that the coupling interface between the battery 304 and the reservoir 306 of the electronic smoking article 302 is an interlocking interface. The electronic smoking article 302 includes a battery 304 and a cylindrical reservoir 306 that contains liquid or other smoking material. The battery 304 is removably coupled to the reservoir 306 via complementary interlocking (e.g., snap-fit) interfaces on the ends of the battery 304 and the reservoir 306. As will be appreciated, a user of the electronic smoking article 302 can push or pull the battery 304 to snap into or away from the reservoir 306 for maintenance purposes, to replace any components, to charge the battery 304, or to perform similar operations. In some embodiments, the electronic smoking article 302 has an LED indicator end on the battery 304. The LED indicator end mimics the lit end of a traditional cigarette and indicates when the electronic smoking article is activated. The mouth end of the reservoir 306 allows a user to breathe into the electronic smoking article 302, drawing air through the battery 304 and into the liquid in the reservoir 306, ultimately drawing the mouth end into the user. In one embodiment, inhalation to draw in air initiates the vaporization process. Alternatively, activation of a circuit closure (mechanical or optical) initiates the vaporization process.

[0047] As previously mentioned, the by-product produced by the electronic smoking article 302 is not smoke, but rather an aerosol or vapor resulting from the volatilization or vaporization of certain components incorporated therein. For example, the inhalable substance may be substantially in vapor form (i.e., a substance in the gas phase at a temperature below its critical point). Alternatively, the inhalable substance may be in aerosol form (i.e., a suspension of fine solid particles or liquid droplets in a gas). The reservoir 306 contains the liquid that is vaporized and delivered to the user.

[0048] FIG. 3B shows a perspective view of an unassembled PUB device 100 and the electronic smoking article of FIG. 3A according to an exemplary embodiment. As shown in FIG. 3B, the PUB device 100 includes a first end connector 310 configured for interlocking interfacing with the battery end of the electronic smoking article 302. The PUB device further includes a second end connector 312 configured for interlocking interfacing with the reservoir end 306 of the electronic smoking article 302. As will be appreciated, the PUB device 100 may include one or more of the components described above and the sensor array 116. Although only one PUB device 100 is shown in FIG. 3B, in some embodiments, more than one PUB device 100 (e.g., modules) may be used with the electronic smoking article 302. In those embodiments, the first end connector 310, the second end connector 312, or both, may be structured to couple with another PUB device 100. In some embodiments, the housing 104 of the PUB device 100 is modified to better fit the configuration of the electronic smoking article 302. As will be appreciated, the size and type of coupling element of the first end connector 110 will depend on the components that make up the interior of the electronic smoking article 302.

[0049] Referring to Figure 3C, a perspective view of the PUB device 100 of Figure 3B assembled with an electronic smoking article 302 (a combination referred to herein as a "PUB delivery system" 300) is shown, according to an exemplary embodiment. The PUB delivery system 300 has the same general form and structure as the original electronic smoking article 302. The PUB device 100 has a size and form structured to minimize physical interference with the intended form of the electronic smoking article 302. The components of the PUB device 100 ensure that the performance and use of the PUB delivery system 300 is substantially similar to the performance and use of the electronic smoking article 302.

[0050] Referring to FIG. 4A , a perspective view of an assembled electronic smoking article 402 according to another exemplary embodiment is shown. The electronic smoking article 402 is similar to the electronic smoking article 302. The difference between the electronic smoking article 402 and the electronic smoking article 302 is the construction of the battery 404 and reservoir 406 of the electronic smoking article 402. The electronic smoking article 402 includes a battery 404 and an oval-shaped reservoir 406 that contains liquid or other smoking material. The battery 404 is removably coupled to the reservoir 406 via complementary interlocking (e.g., snap-fit) interfaces on the ends of the battery 404 and the reservoir 406. As will be appreciated, a user of the electronic smoking article 402 can push or pull the battery 404 to snap into or away from the reservoir 406 for maintenance, to replace any of the components, to charge the battery 404, or to perform similar operations. In some embodiments, the electronic smoking article 402 has an LED indicator on the battery 404. The LED indicator end mimics the lit end of a traditional cigarette and indicates when the electronic smoking article is activated. The mouth end of the reservoir 406 allows the user to breathe into the electronic smoking article 402, drawing air through the battery 404 and into the liquid in the reservoir 406, ultimately drawing the mouth end into the user. In one embodiment, inhalation to draw in air initiates the vaporization process. Alternatively, activation of a circuit closure (mechanical or optical) initiates the vaporization process.

[0051] As previously mentioned, the by-product produced by the electronic smoking article 402 is not smoke, but rather an aerosol or vapor resulting from the volatilization or vaporization of certain components incorporated therein. For example, the inhalable substance may be substantially in vapor form (i.e., a substance in the gas phase at a temperature below its critical point). Alternatively, the inhalable substance may be in aerosol form (i.e., a suspension of fine solid particles or liquid droplets in a gas). The reservoir 406 contains the liquid that is vaporized and delivered to the user.

[0052] Referring to FIG. 4B, a perspective view of an unassembled PUB device 414 and the electronic smoking article of FIG. 4A is shown, according to an exemplary embodiment. The PUB device 414 is similar to the PUB device 100. The difference between the PUB device 414 and the PUB device 100 is the shape of the housing 104 and the first and second end connectors (410, 412) of the PUB device 414. As shown in FIG. 4B, the PUB device 414 includes a first end connector 410 configured for interlocking interfacing with the battery end of the electronic smoking article 402. The PUB device further includes a second end connector 412 configured for interlocking interfacing with the reservoir end 406 of the electronic smoking article 402. Although the PUB device 414 has a different shape, the PUB device 414 may include one or more of the components described above and the sensor array 116. Although only one PUB device 414 is shown in Figure 4B, in some embodiments, more than one PUB device 414 (e.g., modules) may be used with the electronic smoking article 402. In those embodiments, the first end connector 410, the second end connector 412, or both, may be structured to couple with another PUB device 414. In some embodiments, the housing 104 of the PUB device 414 is modified to better fit the configuration of the electronic smoking article 402. As will be appreciated, the size and type of coupling element of the first end connector 110 will depend on the components that make up the interior of the electronic smoking article 402.

[0053] As shown in Figure 4C, the electronic smoking article 402 is assembled with the PUB device 414 of Figure 4B (a combination referred to herein as the "PUB delivery system" 400). The PUB delivery system 400 has the same general form and structure as the original electronic smoking article 402. The PUB device 414 has a size and form configured to minimize physical interference with the intended form of the electronic smoking article 402. The components of the PUB device 414 ensure that the performance and use of the PUB delivery system 400 is substantially similar to the performance and use of the electronic smoking article 402.

[0054] Referring to FIG. 5, a schematic flow diagram illustrating a method 500 for transmitting data from a PUB delivery system 200 is shown, according to an exemplary embodiment. The method 500 will be described in relation to recorded data on the PUB delivery system 200 being synchronized to a user computing system 510 (e.g., laptop, tablet, desktop, mobile computing device, etc.), a secure server system 512 (e.g., database, cloud storage, etc.), and a clinical computing system 514. The PUB delivery system 200 may be, for example, a PUB delivery system similar to the PUB delivery systems (300, 400) of FIGS. 3C and 4C or the PUB-THS delivery systems (600, 700, 800) of FIGS. 6C, 7C, and 8C. As will be appreciated, the exported and imported data and results meet clinical data security and integrity standards.

[0055] Method 500 begins at 502, where the PUB delivery system 200 synchronizes data stored in the on-board memory 120 of the PUB delivery system 200 with a user computing system 510 associated with a user. Data synchronization can occur using the antenna 122 of the PUB device 100. Data synchronization can be triggered, for example, by a charge cycle of components of the PUB delivery system 200, during activation of the PUB delivery system 200, continuously throughout the lifecycle of the PUB delivery system 200, or by a similar triggering event. In some embodiments, the PUB delivery system 200 uses Bluetooth™ technology to facilitate the transfer of data from the memory of the PUB delivery system 200 to the user computing system 510 via data transfer software (e.g., PC, iOS™, or Android™). In other embodiments, the PUB delivery system 200 has a wired interface that allows for a wired connection to the user computing system 510 via data transfer software.

[0056] Data synchronization may include data related to moment-to-moment usage behavior and usage behavior patterns over a period (e.g., hourly, daily, weekly) of user product interaction. The PUB delivery system 200 obtains real-time data related to characteristics of individual usage (puff) behavior (e.g., number, duration, volume, inter-puff interval), how these characteristics change from moment to moment, and how battery characteristics change from moment to moment. Using predetermined and established TPM rates, multiple eMLEs of the PUB delivery system 200 aerosol may be determined. In some embodiments, completion of data synchronization resets data stored in the onboard memory 120 to null values ​​and resynchronizes the onboard clock.

[0057] At 504, the transferred data from the user computing system 510 is transferred over a network to a secure server system 512. The network may include, for example, the Internet, a cellular network, a proprietary cloud network, and similar infrastructure. In some embodiments, the transfer is maintained in accordance with appropriate research data standards.

[0058] At 506, the data stored on the secure server system 512 is accessed by a clinical computing system 514. One or more clinical computing systems 514 may access the secure data on the secure server system 512. As will be appreciated, the data accessed by the clinical computing system 514 may be input into a graphics-based software program for summarization and pattern recognition of electronic smoking article 202 use over a specific period of time. The software may import raw data exported from the database on a per-user / per-trial basis. The data may be processed to summarize and apply algorithms to calculate individual product use factors, product usage rates and / or patterns, and eMLE. Within the software program, information associated with the particular electronic smoking article 202 under evaluation (e.g., TPM data values) necessary to perform the analysis can be modified. The data generated by this process may be uploaded to the secure server system 512.

[0059] In some embodiments, data hosted on the secure server system 512 may be used to communicate 508 with user computing systems 510 to present additional information to the PUB delivery system 200. Such information may include, for example, software updates for PUB devices, security updates for data transfer and storage, feature changes, feature additions, data presentation to users, user usage statistics, additional control features, authorized user updates, data storage updates, etc. For example, communication may allow the PUB delivery system to monitor and capture data related to specific characteristics.

[0060] In some embodiments, a PUB device may be implemented with a THS electronic smoking article (e.g., a heated electronic cigarette) to capture usage data characteristics of smoking behavior using the THS electronic smoking article. As used herein, "PUB-THS device" refers to a PUB device configured for use with a THS electronic smoking article. Generally, a THS electronic smoking article includes a battery, a heating element, a control device, and a cavity for receiving a tobacco stick (e.g., a tobacco source). As will be understood, a THS electronic smoking article is a type of electronic smoking article. Depending on the type of THS electronic smoking article, the tobacco stick may be a removable element similar in shape and size to a conventional cigarette that can be removed after use. For example, the tobacco stick may have a tobacco end that is inserted into the tobacco stick cavity and a mouth end to receive tobacco aerosol. In other embodiments, the tobacco stick is in the form of a removable cigarette that can be placed adjacent to the heating element in a cigarette holder and removed / cleaned after use. While THS smoking articles are described as using a tobacco heating element to heat the tobacco element / product within a tobacco stick, PUB-THS devices may be used to monitor the heat-not-burn use of a wide variety of smoking products and consumables. For example, PUB-THS devices may be used to monitor smoking (e.g., consumption amount, heating temperature, duration, etc.) and non-smoking (e.g., movement, position, break time, etc.) behaviors of smoking articles that heat nicotine, tetrahydrocannabinol, cannabinoids, or similar heat-not-burn consumables. PUB-THS devices may also be used to monitor the heat-not-burn use of various pharmaceuticals.

[0061] The heating element is structured to heat the tobacco stick (as with combustion) to produce tobacco vapor or aerosol rather than tobacco smoke. As will be appreciated, the tobacco stick may contain little or no tobacco and may include an alternative consumable product that is heated and not combusted. The heating element may surround the tobacco stick, e.g., heat the outside of the tobacco stick. Alternatively, the heating element may be inserted into the tobacco stick as a protrusion, e.g., entering the tobacco stick from the inserted tobacco end and heating the tobacco surrounding the heating element. In some embodiments, both configurations (inside-out and outside-in) are implemented. Typically, the heating element heats the tobacco up to 350°C. The controller is configured to monitor and control the temperature of the heating element to ensure a consistent taste experience and avoid overheating. The generated tobacco aerosol may contain water, glycerol, and other vaporized substances (e.g., flavors) present in the original tobacco mixture. A user of a THS electronic smoking article activates / starts the heating element to initiate a puff. In some embodiments, a user of a THS electronic smoking article may need to press a button to activate the heating element. In other configurations, the user begins to blow into the THS electronic smoking article to activate the heating element. In some embodiments, a user may activate the THS electronic smoking article through a fingerprint scan, activation of a mobile application on a user device, remote activation, or other activation mechanism.

[0062] Beneficially, the PUB-THS device is configured for retrofitting into various THS electronic smoking articles so as to be compatible with a wide variety of battery-tank, battery-tobacco stick, or battery cartridge connections of the THS electronic smoking article. The PUB-THS device includes at least one connector on either end of the board or housing so that the PUB-THS device can be attached to the THS electronic smoking article. Generally, in some embodiments, the PUB-THS device is attached to the portion of the THS electronic smoking article where airflow enters the heater chamber, thereby enabling the PUB-THS device to record the actual passage of air into the heating chamber without interfering with the airflow necessary for normal product function. In other embodiments, the PUB-THS device is positioned between the power source and the heating chamber of the THS electronic smoking article. In other words, the PUB-THS device includes a connector for the heater element portion of the THS electronic smoking article at one end and a connector for the battery portion of the THS electronic smoking article at the opposite end. In another embodiment, the PUB-THS device may be configured to surround the portion of the THS electronic smoking article that the user interacts with (e.g., a tobacco stick). For example, the PUB-THS device may be a shroud shaped like a protrusion formed by a tobacco stick loaded into the THS electronic smoking article. In either embodiment, the components of the PUB-THS device are contained within a housing that allows the PUB-THS device to be used with a wide range of THS electronic smoking articles without interfering with the use and / or function of the THS electronic smoking article. Additionally, the PUB-THS device includes one or more venturi airflow chambers disposed (e.g., molded, coupled, etc.) within the internal cavity of the PUB-THS device, the venturi airflow chambers being structured to capture pressure across the narrowed portion of the venturi tube, thereby enabling accurate measurement of changes in air pressure and airflow. Alternatively, the PUB-THS device may include one or more orifices disposed (e.g., molded, coupled, etc.) in an internal cavity of the PUB-THS device, the orifices being structured to capture pressure across a constricted portion of the orifice, thereby enabling accurate measurement of changes in air pressure and air flow.

[0063] As will be appreciated, PUB-THS devices can record and detect battery activation, battery characteristics (e.g., wattage, voltage, and resistance), location (e.g., global position), device orientation, device movement, temperature of the airflow entering the THS electronic smoking article, and sound of the airflow entering the THS electronic smoking article. With respect to user usage, PUB-THS devices can measure usage characteristics, patterns from time to time and over a period of time (e.g., hourly, daily, weekly), puff behavior (e.g., number, duration, volume, interval between puffs, etc.), and changes in characteristics throughout smoking time or over a period of time. Generally, PUB-THS devices include an array of sensors for recording product usage characteristics, an onboard memory for storing collected data, an onboard rechargeable power source, a wireless (e.g., Bluetooth™) communication array for transferring data to an external storage location, a first connector for the tank end, and a second connector for the battery end. Once the PUB-THS device is installed on a THS electronic smoking article, data monitoring and collection may be triggered or continued by activating and deactivating the THS electronic smoking article. After partial data acquisition is complete, the PUB-THS device may synchronize with a wireless communication-compatible computing device (e.g., desktop, laptop, tablet, smartphone, etc.) and upload the data to a secure database. The data may be exported to any statistical software package for subsequent analysis or to task-specific summarization software. As will be appreciated, the PUB-THS device may be utilized to capture and track THS electronic smoking article usage data for behavioral modeling, and in clinical and non-clinical studies to track usage and provide information on usage patterns.

[0064] Referring to FIG. 6A, a perspective view of a THS electronic smoking article 602 and a PUB-THS device 610 are shown in an unassembled state, according to an exemplary embodiment. The THS electronic smoking article 602 includes a housing 604 having a first end 605, a second end 607, and an activation switch 609. The second end 607 includes an airflow port 608 configured to facilitate airflow through the housing 604 of the THS electronic smoking article 602. The first end 605 includes a tobacco stick cavity (not shown) that receives a tobacco stick 606. In some embodiments, the tobacco stick 606 is a permanent structure on the housing 604 that is in fluid communication with the tobacco stick cavity, into which a tobacco stick or loose-leaf tobacco can be inserted and heated. The mouth-end of the tobacco stick 606 allows a user to blow into or draw on the THS electronic smoking article 602, drawing air through the airflow port 608, which travels through the THS electronic smoking article 602 and the tobacco, and ultimately to the user through the mouth-end. In one embodiment, the air drawn in by inhalation initiates the vaporization process. Alternatively, the vaporization process is initiated by activation of a circuit closure (mechanical or optical), such as an activation switch 609.

[0065] Within the THS electronic smoking article 602 (e.g., inside the housing 604 (not shown)) may be a circuit board, a battery, a heating element, and a tobacco stick cavity. The battery provides power to the THS electronic smoking article 602, including the heating element. The circuit board is structured to activate, deactivate, and control the heating and use of the heating element, as well as control other components of the THS electronic smoking article 602. The heating element may surround the tobacco stick 606 and heat the tobacco from the outside in, may be inserted into the tobacco stick 606 and heat the tobacco from the inside out, or may be a combination of the two. As another example, in some embodiments, an induction heating configuration may be used, which may include an induction coil (or multiple induction coils) and one or more susceptors, which may include susceptor particles, positioned adjacent to, inserted into, and / or integrated into the tobacco stick 606. In some embodiments, the THS electronic smoking article 602 has an LED indicator that shows when the heating element is activated. As shown in Figure 6A, the LED is located around the activation switch 609. The activation switch 609 allows a user to activate or deactivate the heating element and use the THS electronic smoking article 602.

[0066] As shown in FIG. 6A , the PUB-THS device 610 includes a housing 616 having a first end 618 and a second end 620. The second end 620 is configured to interface with the second end 607 of the THS electronic smoking article 602 via a connector. In some embodiments, the connector is part of a control device (not shown) internal to the housing 616. In other embodiments, the connector is part of the housing 616. The first end 618 includes an airflow port (not shown) that is in fluid communication with the airflow port 614 of the second end 620. The second end 620 of the PUB-THS device 610 includes the airflow port 614 and a sensor holder 612. The airflow port 614 is in fluid communication with a venturi tube internal to the housing 616. One or more venturi airflow chambers (not shown) may be molded into the internal cavity of the PUB-THS device 610. The use of a venturi airflow chamber enhances the PUB-THS device 610's ability to accurately measure changes in air pressure / airflow as the subject uses the THS. Specifically, the pressure transducer sensor in the PUB-THS device 610 can measure changes in pressure differential across the constricted portion of the venturi tube to determine airflow. For example, the inter-puff interval ("IPI") may be measured by recording the time between the end of a puff (airflow end) and the beginning of the next puff (e.g., airflow start), as long as these events occur during a period when the heating element is at temperature and a consumable product (e.g., a cigarette) is present to be consumed. This data is stored and uploaded in raw data format, date / time stamped, and used to generate puff, rapid puff, and sub-puff counts and duration values, as well as IPI counts and duration values. As will be appreciated, one or more orifices may be positioned within the housing 616 to enhance the PUB-THS device 610's ability to accurately measure changes in air pressure / airflow as the subject uses the THS.

[0067] More specifically, the PUB-THS device 610 monitors, records, and transmits multiple user usage data and THS electronic smoking article system data. The PUB-THS device 610 is structured to have a shape, size, and connector that allows it to be adapted to interface with the bottom of the THS electronic smoking article 602 without interfering with the operation of the THS electronic smoking article 602. As will be appreciated, the PUB-THS device 610 is durable and can be used in both controlled and restricted environments, both under supervision and without supervision, in accordance with product safety standards for mobile laboratory equipment. Within the housing 616 is a control unit (not shown). The control unit may be similar to the control unit of the PUB device 100 of FIG. 1 , configured to be disposed within the housing 616 of the PUB-THS device 610. The control unit includes a sensor array, a PUB battery, onboard memory, and an antenna. The control unit is structured to monitor, record, and store multiple data and characteristics of the user and the THS electronic smoking article 602. The control device is structured to interface with a wide variety of THS electronic smoking articles and to have a size, and in some embodiments, a connector, that interferes as little as possible with the intended configuration of the THS electronic smoking article 602.

[0068] The controller captures real-time data related to individual puff behavior characteristics (e.g., number, duration, volume, inter-puff interval), changes in puff characteristics from time to time, changes in puff characteristics over a period of time, and similar information. For example, captured puff characteristics may include, but are not limited to, puff volume (ml), puff duration (s), number of puffs, number of sub-puffs, average and peak flow rate (ml / s), average and peak draft (ml / s), average and peak resistance, average and peak pressure drop (mmWg), inter-puff interval (s), and light duration (s). The controller may also capture battery characteristics (e.g., wattage, voltage, and resistance), location, device orientation, device movement, temperature of the airflow entering the THS electronic smoking article 602, and sound of the airflow entering the THS electronic smoking article 602. The controller facilitates storage of data characteristics related to user usage behavior from time to time and usage patterns over periods of product interaction (e.g., hourly, daily, weekly). The controller and associated elements may be physically implemented on a circuit board.

[0069] The on-board memory is structured to store the data and characteristics collected by the sensor array. The on-board memory may be, for example, flash memory or electrically erasable programmable read-only memory ("EEPROM") memory. The on-board memory should provide sufficient memory capacity to allow for storage of the highest estimated data load generated over a set period of time, for example, seven days. In some embodiments, the on-board memory may be reset to a null value, and the on-board clock may be resynchronized once the data is uploaded. In other embodiments, the on-board memory is structured to retain all data until the on-board memory reaches capacity. The on-board memory may store the data in raw data format, date and time stamp it, and use it to determine a wattage value. As will be appreciated, the wattage value combined with the puff duration value may be used to generate a total particulate matter ("TPM") constant for the estimated mouth-level exposure ("eMLE") of the aerosol measurement. The data captured by the sensor array is stored in the on-board memory both as individual data points and as part of a cumulative, date and time stamped record.

[0070] The PUB-THS battery includes an on-board rechargeable battery. The PUB-THS battery may also be a rechargeable solid-state battery. The PUB-THS battery is structured to power the PUB-THS device 610 and ensure that the performance of data collection by the PUB-THS device 610 is not affected by the battery's performance. The PUB-THS battery should be able to maintain a charge through the subject's highest estimated level of use. In some embodiments, the PUB-THS battery lasts at least seven days without needing to be recharged. In some embodiments, the PUB-THS battery is recharged when the THS electronic smoking article 602 is recharged. In other embodiments, the PUB-THS device 610 includes a charging port on the housing 616 that can charge the PUB-THS battery. In some embodiments, the PUB-THS device 610 does not have a PUB-THS battery. Instead, the PUB-THS device 610 draws power from the battery in the THS electronic smoking article 602.

[0071] The antenna is configured to transmit data collected by the sensor array and stored by the on-board memory. The antenna may be configured to upload data during the electronic smoking article's charging cycle, during activation of the THS electronic smoking article 602, continuously throughout the lifecycle of the THS electronic smoking article 602, or during a similar trigger event. In some embodiments, the on-board memory may be reset to a null value, and the on-board clock may be resynchronized when data upload by the antenna ends. In some embodiments, the PUB-THS device uses wireless technology (e.g., Bluetooth™ technology) to facilitate the transfer of data from the PUB-THS device's 610 memory to a secure location (e.g., a server location) via data transfer software (e.g., PC, iOS™, or Android™). The antenna is designed to minimize interference with generated aerosols by transmitting data via Bluetooth™ or other wireless communication technology. In other embodiments, the antenna has a wired interface that allows for a wired connection to the secure location via data transfer software. The security and integrity of the data during its transit from the antenna of the PUB-THS device 610 to the computer or smart device to the database server may be maintained in accordance with appropriate research data standards. In some embodiments, the data hosted in the secure database may be used to communicate with a PC and / or smart device (e.g., a smartphone and / or tablet) to present additional information to the user of the PUB-THS device 610.

[0072] The sensor array is configured to monitor and record one or more data characteristics of the THS electronic smoking article 602 and user usage data. The sensor array is configured to monitor and record a wide variety of user usage characteristics and data. The sensor array can capture real-time data related to individual usage behavior characteristics (e.g., number, duration, capacity, inter-puff interval), how these characteristics change from time to time, and how battery characteristics such as power (e.g., wattage) change from time to time. The sensor array may measure the time between the end of a puff (e.g., battery deactivation) and the start of the next puff (e.g., battery activation), also known as IPI. As will be appreciated, puff statistics captured by the sensor array can be used to capture puff, rapid puff, and sub-puff counts and duration values, as well as IPI counts and duration values. In some embodiments, the sensor array monitors and captures battery or heating element activation coinciding with the start of a puff and measures the time the battery is activated to determine puff duration. Additionally, the sensor array may capture the temperature of the heater during the duration of each puff. In other embodiments, the sensor array may record the end of a puff when the battery is no longer active.

[0073] With respect to the THS electronic smoking article 602, the sensor array may include specific sensors for detecting the THS electronic smoking article's battery activation, battery characteristics (e.g., wattage, voltage, current, and resistance), or battery age (e.g., length of smoking time). As will be appreciated, data captured by the sensor array is stored in on-board memory, both as individual data points and as part of a cumulative, time-stamped record. As described in detail above, the sensor array may include pressure transducer sensors for measuring changes in pressure differential across one or more venturi airflow chambers or orifices.

[0074] The sensor array may include hardware sensors that detect the presence of a tobacco stick 606 within the THS electronic smoking article 602. The hardware sensors may be used to verify that a stick, loose-leaf, or other form of tobacco stick 606 is properly inserted into the THS electronic smoking article 602 and properly heated by the heating element. The sensors may be configured to identify the type of consumable (e.g., tobacco and non-tobacco products, or specific variations thereof) and the quantity of consumable used in the THS electronic smoking article 602. The sensors may determine the tobacco stick insertion pressure, tobacco stick quantity (in the case of loose-leaf tobacco), loading duration, removal frequency, and other interactions between the tobacco stick 606 and the THS electronic smoking article 602. In some embodiments, the sensor array may verify that the tobacco stick is an authentic (e.g., authorized, non-counterfeit, etc.) tobacco stick. Such unauthorized tobacco sticks may not meet the quality, performance, and safety parameters of the original manufacturer.

[0075] In some embodiments, the sensor array includes hardware sensors that track the position of the THS electronic smoking article during use. For example, a nine-axis gyroscope is used to capture the orientation of the PUB-THS device 610, an accelerometer is used to capture the movement of the PUB-THS device 610, and a GPS or other satellite navigation system is used to capture the location of the PUB-THS device 610. In such embodiments, a position tracking device can be used to generate data regarding the position of the THS electronic smoking article 602 in relation to the positional relationship between the first end 605 and second end 607 of the THS electronic smoking article 602. Advantageously, recording this positional relationship allows researchers to determine how the user held the THS electronic smoking article 602 while performing a puff. Determining whether the user smoked the THS electronic smoking article 602 while lying on a couch with the battery above the reservoir, compared to whether the user held the THS electronic smoking article 602 while sitting in a manner similar to a traditional cigarette, can provide more information regarding normal use of the THS electronic smoking article 602 and provide details regarding reservoir leaks and malfunctions / failures of the THS electronic smoking article 602. Additionally, a position sensor may be used to track the speed of movement of the THS electronic smoking article 610 from one position to another, such that linear acceleration may be used to identify the start or end of use of the THS electronic smoking article 602.

[0076] The sensor array may include a hardware sensor that detects changes in ambient temperature within the airway port of the THS electronic smoking article 602. The temperature change may be used to distinguish between the initiation of a puff and continued use of the THS electronic smoking article 602. In some embodiments, the PUB-THS device 610 may include a hardware sensor that detects the speed of movement of the PUB-THS device 610 from one location to another. In these embodiments, the linear acceleration of the PUB-THS device 610 is measured with respect to use / non-use to identify the start of a period of product use. In other embodiments, the PUB-THS device 610 may include a hardware sensor that records the sound frequency of air passing through the dedicated airway port of the PUB-THS device 610. In such embodiments, passive acoustic measurements may be used to provide information for understanding puff speed and the general shape of individual puff characteristics.

[0077] The PUB-THS device 610 may also include hardware sensors that track and record events measured by other components that make up the PUB-THS device 610. Advantageously, this tracking is time-stamped so that every recorded event forms a cumulative record. The cumulative record can be tracked and exported to any statistical software package or task-specific summarization software for subsequent analysis. In other embodiments, the PUB-THS device 610 may receive externally processed cumulative records via download to the PUB-THS device 610. In such embodiments, the PUB-THS device 610 may perform additional analysis or task-specific summarization of the externally processed data. In other embodiments, the PUB-THS device 610 performs information and feedback analysis of the cumulative records within the device. In other embodiments, the PUB-THS device 610 may include a photo sensor, mechanical sensor, and / or pressure sensor that detects whether the PUB-THS device 610 has been removed from the battery and / or tank end of the electronic smoking article.

[0078] In some embodiments, the PUB-THS device 610 includes a toggle function on the control device. The toggle function can turn on, off, limit, or change one or more data characteristics monitored and recorded by the PUB-THS device 610. For example, the toggle function may limit the total number of puffs (e.g., in terms of duration, number, or a combination of both) generated over a specific period (e.g., minute / hour / day / week, etc.) to limit the number of uses of a THS electronic smoking article. In other embodiments, the PUB-THS device 610 includes a single activation button that can be used to trigger or mark an event (e.g., date / time / location) that occurs during use of the electronic smoking article. In some embodiments, the PUB-THS device 610 includes a screen (e.g., an LCD, LED, OLED, or other suitable screen) inserted into the housing 616. The screen displays the status of any of the events recorded or managed by the PUB-THS device 610. The screen may also facilitate a user's adjustment of the data monitored and recorded by the sensor array, for example, via a toggle function. A user may use the screen to select an "off" option for one or more data characteristics to be collected, such as the user's location while using the PUB-THS device 610. The toggle function may include the ability to change the wattage delivered to the heating element within the heating chamber of the THS electronic smoking article 602. The user may use this toggle function to change the total wattage delivered to a level as low as 0 to an amount less than the wattage produced by the THS battery. Additionally, the toggle function may be used to track and record other components comprising the PUB-THS device 610 or events measured by the PUB-THS device 610.

[0079] The PUB-THS device 610 may also include an identifier associated with the structure and characteristics of the PUB-THS device 610. The identifier is updatable for each user during use of the PUB-THS device 610. As will be appreciated, this may enable a user to switch between clinical (e.g., data captured for third-party analysis) and non-clinical (e.g., data captured for the user's analysis) testing. The identifier may be incorporated into a data set to enable matching of data type (e.g., clinical, non-clinical, specific user, type of PUB-THS device 610) and data source. Additionally, the identifier may be encoded into the PUB-THS device 610, visually apparent through an embossed portion of the housing 616 of the PUB-THS device 610, or affixed by a label to the housing 616 of the PUB-THS device 610. In some embodiments, the sensor array may include access control via a biometric security sensor, such as a fingerprint sensor for detecting fingerprint characteristics. In those embodiments, use of the THS electronic smoking article 602 and / or data characteristic collection may occur only if the fingerprint sensor captures a fingerprint from an authorized user (e.g., associated with a PUB-THS device). As will be appreciated, biometric security sensors may be configured to capture a wide variety of biometric data from authorized users (e.g., iris, voice, gait, etc.).

[0080] In certain embodiments, the PUB-THS device 610 is configured as a series of modules. A single-module PUB-THS device 610 may be positioned between the battery end and the tank end of the THS electronic smoking article 602. A single-module PUB-THS device 610 may be configured to monitor and record single or multiple data or characteristics. Multiple modular PUB-THS devices 610 may be connected along the THS electronic smoking article 602 to monitor and record single or multiple data or characteristics. As will be appreciated, the modular PUB-THS device 610 may tailor the THS electronic smoking article 602 to capture a specific subset of data and characteristics. For example, a user may want to utilize the PUB-THS device 610 to capture data characteristics but not allow location data to be transmitted or captured. Thus, a user's THS electronic smoking article 602 may include a modular PUB-THS device 610 that monitors and records data or characteristics that are not related to location. In some embodiments, the PUB-THS device 610 includes a chip structured to interface with the THS electronic smoking article 602 and collect at least one usage data characteristic.

[0081] As will be appreciated, data collected by the sensor array 116 may be input into a graphics-based software program for summarization and pattern recognition of THS electronic smoking article 602 use over a specific period of time. The software may import raw data exported from the database on a per-user / per-trial basis. The data may be processed to summarize and apply algorithms to calculate individual product use factors, product usage rates and / or patterns, and eMLE of aerosol measurements. Within the software program, information associated with the specific THS electronic smoking article 602 under evaluation (e.g., TPM data values) necessary to perform the analysis can be modified. Data generated by this process may be uploaded to the PUB-THS device 610 database. As will be appreciated, the imported data and exported results meet data security and integrity standards. In other embodiments, data collected by the sensor array is sent to task-specific summarization software.

[0082] In some embodiments, the control device includes a coupling element structured to removably couple to and interface with the airflow port 608 and second end 607 of the THS electronic smoking article 602. A variety of different coupling mechanisms may be used to attach the PUB-THS device 610 to the THS electronic smoking article 602, including protrusions extending from the control device that interface with the THS electronic smoking article 602. As will be appreciated, the size and type of coupling element will depend on the components comprising the interior of the particular THS electronic smoking article. In some embodiments, the PUB-THS device 610 is removably coupled to the THS electronic smoking article 602 via complementary interlocking (e.g., snap-fit) interfaces on the second end 620 of the PUB-THS device 610 and the second end 607 of the THS electronic smoking article 602. As will be appreciated, a user of the PUB-THS device 610 can push the PUB-THS device 610 to snap-fit ​​onto the THS electronic smoking article 602 for maintenance, and then pull them apart to replace any components, charge batteries, or perform similar operations. Alternative complementary interlocking interfaces on the second end 620 of the PUB-THS device 610 and the second end 607 of the THS electronic smoking article 602 can use, for example, twist fits, press fits, friction fits, overlap lock fits, and similar connection interfaces.

[0083] FIG. 6B shows a perspective view of an unassembled PUB-THS device 610 and the THS electronic smoking article 602 of FIG. 6A according to an exemplary embodiment. As shown in FIG. 6B, the PUB-THS device 610 includes a connector on a second end 620 configured for interlocking interface with the second end 607 of the THS electronic smoking article 602. The PUB-THS device 610 is attached to the THS electronic smoking article 602 so as to record the functions and characteristics of the THS electronic smoking article 602 without interfering with the airflow necessary for proper function. As will be appreciated, the PUB-THS device 610 may include one or more of the components described above and a sensor array. While only one PUB-THS device 610 is shown in FIG. 6B, in some embodiments, one or more PUB-THS devices 610 (e.g., modules) may be used with the THS electronic smoking article 602. In those embodiments, additional connectors on the first end 618, second end 620, or both ends may be structured to couple with another PUB-THS device 610. In some embodiments, the housing 616 of the PUB-THS device 610 is modified to better fit the configuration of the THS electronic smoking article 602. As will be appreciated, the size and type of coupling element of the connector on the second end 620 will depend on the components that make up the exterior and interior of the THS electronic smoking article 602.

[0084] Referring to Figure 6C, a perspective view of the PUB-THS device 610 of Figure 6B assembled with a THS electronic smoking article 602 (a combination referred to herein as a "PUB-THS delivery system" 600) is shown, according to an exemplary embodiment. The PUB-THS delivery system 600 has the same general form and structure as the original THS electronic smoking article 602. The PUB-THS device 610 has a size and form structured to minimize physical interference with the intended form of the THS electronic smoking article 602. The components of the PUB-THS device 610 ensure that the performance and use of the PUB-THS delivery system 600 is substantially similar to the performance and use of the THS electronic smoking article 602.

[0085] Referring to FIG. 7A, a perspective view of an assembled THS electronic smoking article 702 according to another exemplary embodiment is shown. The THS electronic smoking article 702 is similar to the THS electronic smoking article 602. As previously mentioned, the by-product produced by the THS electronic smoking article 702 is not smoke, but rather an aerosol or vapor resulting from heating the tobacco within the tobacco stick 706. For example, the inhalable substance may be substantially in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). The THS electronic smoking article 702 includes a housing 704 having a first end 705, a second end 707, and an activation switch 709. The second end 707 includes an airflow port 708 configured to facilitate airflow through the housing 704 of the THS electronic smoking article 702. The first end 705 includes a cavity (not shown) for receiving the tobacco stick 706. In some embodiments, the tobacco stick 706 is a permanent structure on the housing 704 that is in fluid communication with a tobacco stick cavity into which a tobacco stick or loose-leaf tobacco can be inserted and heated. The mouth end of the tobacco stick 706 allows a user to blow into or draw on the THS electronic smoking article 702, drawing air through the airflow port 708, which travels through the THS electronic smoking article 702 and the heated tobacco, and ultimately to the user through the mouth end. In one embodiment, inhalation to draw in air initiates the vaporization process. Alternatively, activation of a circuit closure (mechanical or optical), such as an activation switch 709, initiates the vaporization process.

[0086] Referring to Figure 7B, a perspective view of an unassembled PUB-THS device 710 and the THS electronic smoking article 702 of Figure 7A is shown, according to an exemplary embodiment. The PUB-THS device 710 is similar to the PUB-THS device 610, such that the internal structure of the PUB-THS device 710 (e.g., controls, sensory array, etc.) is similar or identical to the PUB-THS device 610 in form and / or function. The differences between the PUB-THS device 710 and the PUB-THS device 610 are the shape of the housing 716 of the PUB-THS device 710, the connecting elements, and the connection location of the PUB-THS device 710. As shown in Figure 7B, the PUB-THS device 710 encloses a portion of the first end 705 of the THS electronic smoking article 702 and the tobacco stick 706 protruding from the first end 705. In other words, the PUB-THS device 710 includes a portion (e.g., a hollow protrusion) that fits over the location of a loaded tobacco stick and / or a location where a user interacts to consume the tobacco product, in a manner similar to a shroud. The PUB-THS device 710 includes a protrusion 712 having an airflow opening 714 extending from a second end 718 of a housing 716, and a first end 720 that interfaces to couple with a first end 720 of a THS electronic smoking article 702.

[0087] The protrusion 712 is in fluid communication with the tobacco stick 706 such that inhalation through the airflow opening 714 is substantially similar to consuming a cigarette without the PUB-THS device 710 installed (e.g., the THS electronic smoking article 702 alone). Although the PUB-THS device 710 has a different shape, the PUB-THS device 710 may include one or more of the components described above (e.g., a controller, a sensor array, etc.). While only one PUB-THS device 710 is shown in FIG. 7B , in some embodiments, one or more PUB-THS devices 710 (e.g., modules) may be used with the THS electronic smoking article 702. In those embodiments, the first end 720, the second end 718, or both, may be structured to couple with another PUB-THS device 710. In some embodiments, the housing 716 of the PUB-THS device 710 is modified to better fit the shape of the THS electronic smoking article 702. As will be appreciated, the size and type of the connecting element on the first end 720 and / or the interior of the housing 716 will depend on the components that make up the interior of the THS electronic smoking article 702.

[0088] A wide variety of different coupling mechanisms may be used to attach the PUB-THS device 710 to the THS electronic smoking article 702, including a snap-fit ​​interface on the housing 716 that interfaces with the THS electronic smoking article 702. As will be appreciated, the size and type of coupling element will depend on the components that make up the interior of the particular THS electronic smoking article. In some embodiments, the PUB-THS device 710 is removably coupled to the THS electronic smoking article 702 via complementary interlocking (e.g., snap-fit) interfaces on the first end 720 of the PUB-THS device 710 and the first end 705 of the THS electronic smoking article 702. As will be appreciated, a user of the PUB-THS device 710 can press the PUB-THS device 710 to snap-fit ​​onto the THS electronic smoking article 702 for maintenance, and then pull them apart to replace any components, charge batteries, or perform similar operations. Alternative complementary interlocking interfaces on the first end 720 of the PUB-THS device 710 and the first end 705 of the THS electronic smoking article 702 can use, for example, twist fits, press fits, friction fits, overlap lock fits, and similar connection interfaces.

[0089] As shown in Figure 7C, the THS electronic smoking article 702 is assembled with the PUB-THS device 710 of Figure 7B (a combination referred to herein as the "PUB-THS delivery system" 700). The PUB-THS delivery system 700 has the same general form and structure as the original THS electronic smoking article 702. The PUB-THS device 710 has a size and form structured to minimize physical interference with the intended form of the THS electronic smoking article 702. The components of the PUB-THS device 710 ensure that the performance and use of the PUB-THS delivery system 700 is substantially similar to the performance and use of the THS electronic smoking article 702.

[0090] Referring to FIG. 8A, a perspective view of an assembled THS electronic smoking article 802 according to another exemplary embodiment is shown. The THS electronic smoking article 802 is similar to the electronic smoking article 202 of FIGS. 2A-2C. The THS electronic smoking article 802 differs from the electronic smoking article 202 in the use of a tobacco stick 806 on the mouth end of a heating element 805. The THS electronic smoking article 802 includes a battery compartment 804, a heating element 805, and a cylindrical tobacco stick 806 containing tobacco or other smoking material. An airflow 808 may be drawn from the battery compartment 804 as the user blows or draws air through the battery compartment 804, through the heating element 805, into the tobacco stick 806, and finally through the mouth end. In some embodiments, the airflow 808 may enter from the side of the battery compartment 804, for example, at or adjacent to the connector 814 of the heating element 805.

[0091] The battery compartment 804 contains a battery 812, a circuit board 822, an LED indicator 820, and an activation switch 818. The circuit board 822 is powered by the battery 812 and operably connected to the LED indicator 820, the activation switch 818, and the heating element 805. The circuit board 822 is configured to control the operation of the THS electronic smoking article 802, including the activation, temperature control, and deactivation of the heating element 805. The activation switch 818 is operably connected to the circuit board 822 and allows a user to control the use (e.g., heating) of the THS electronic smoking article 802. In one embodiment, the heating process is initiated by inhalation to draw in air. Alternatively, the heating process is initiated by activation of a circuit closure (mechanical or optical). As previously mentioned, the product produced by the THS electronic smoking article 802 is not smoke, but rather an aerosol or vapor resulting from the heating of the tobacco within the tobacco stick 806. For example, the inhalable substance may be substantially in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). In some embodiments, the THS electronic smoking article 802 has an LED indicator 820 on the battery compartment 804. The LED indicator end indicates when the THS electronic smoking article 802 is activated. The battery compartment 804 is removably coupled to the heating element 805 via a complementary torsional (e.g., twist) interface on the connector end 816 of the battery compartment 804 and the connector end 814 of the heating element 805. As will be appreciated, a user of the THS electronic smoking article 802 can unscrew the battery compartment 804 from the heating element 805 for maintenance purposes to replace any components, charge the battery compartment 804, or perform similar operations.

[0092] The tobacco stick 806 is inserted into the heating element 805 so that the heating element surrounds the tobacco stick 806. In some embodiments, the heating element 805 protrudes into the tobacco stick 806, heating the tobacco from the inside. The mouth end of the tobacco stick 806 allows a user to blow into or draw on the THS electronic smoking article 802, drawing in air that flows (808) through the battery compartment 804, into the tobacco stick 806, and ultimately to the user through the mouth end.

[0093] Figure 8B shows a perspective view of an unassembled PUB-THS device 810 and the THS electronic smoking article 802 of Figure 8A. The PUB-THS device 810 is similar to the PUB-THS device 610 such that the internal structure (e.g., controls, sensory array, etc.) of the PUB-THS device 810 is similar in form and / or function to or identical to the PUB-THS device 610. The differences between the PUB-THS device 810 and the PUB-THS device 610 are the shape of the housing of the PUB-THS device 810, which has two connecting elements, and the location of the connection of the PUB-THS device 810 between the battery compartment 804 and the heating element 805 of the THS electronic smoking article.

[0094] The PUB-THS device 810 includes a first end connector 826 structured for a torsional interface with a battery connector end 816 of the THS electronic smoking article 802. The PUB-THS device 810 further includes a second end connector 824 structured for a torsional (e.g., twisting) interface with a heating element connector end 814 of the THS electronic smoking article 802. As will be appreciated, the PUB-THS device 810 may include one or more of the components described above (e.g., a controller, a sensor array, etc.). Alternative, complementary interlocking interfaces on the first end connector 826 and the second end connector 824 may be used to interface with appropriate interfaces on the THS electronic smoking article 802, such as a twist fit, press fit, friction fit, overlap lock fit, or similar connection interfaces. Although only one PUB-THS device 810 is shown in Figure 8B, in some embodiments, more than one PUB-THS device 810 (e.g., modules) may be used with the THS electronic smoking article 802. In those embodiments, the first end connector 826, the second end connector 824, or both ends may be structured to couple with another PUB-THS device 810. In some embodiments, the housing of the PUB-THS device 810 is modified to better fit the configuration of the THS electronic smoking article 802.

[0095] Referring to Figure 8C, a perspective view of the PUB-THS device 810 of Figure 8B assembled with a THS electronic smoking article 802 (a combination referred to herein as a "PUB-THS delivery system" 800) is shown, according to an exemplary embodiment. The PUB-THS delivery system 800 has the same general form and structure as the original THS electronic smoking article 802. The PUB-THS device 810 has a size and form structured to minimize physical interference with the intended form of the THS electronic smoking article 802. The components of the PUB-THS device 810 ensure that the performance and use of the PUB-THS delivery system 800 is substantially similar to the performance and use of the THS electronic smoking article 802.
