The present disclosure relates to heat-not-burn (HNB) aerosol generating devices and capsules configured to generate an aerosol without involving a substantial pyrolysis of an aerosol-forming substrate.
Some electronic devices are configured to heat a plant material to a temperature that is sufficient to release constituents of the plant material while keeping the temperature below a combustion point of the plant material so as to avoid any substantial pyrolysis of the plant material. Such devices may be referred to as aerosol-generating devices (e.g., heat-not-burn aerosol-generating devices), and the plant material heated may be tobacco and/or cannabis. In some instances, the plant material may be introduced directly into a heating chamber of an aerosol generating device. In other instances, the plant material may be pre-packaged in individual containers to facilitate insertion and removal from an aerosol-generating device.
New and useful systems, apparatuses, and methods for cooldown alert systems for aerosol-generating devices are set forth in the appended claims. Illustrative embodiments are also provided to enable a person skilled in the art to make and use the claimed subject matter.

The various features and advantages of the non-limiting embodiments herein may become more apparent upon review of the detailed description in conjunction with the accompanying drawings. The accompanying drawings are merely provided for illustrative purposes and should not be interpreted to limit the scope of the claims. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted. For purposes of clarity, various dimensions of the drawings may have been exaggerated.
Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.
Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiments. Like numbers refer to like elements throughout the description of the figures.
It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.
Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below,” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” specify the presence of stated features, integers, steps, operations, and/or elements, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or groups thereof.
When the terms “about” or “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value includes a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical value. Moreover, when the terms “generally” or “substantially” are used in connection with geometric shapes, it is intended that precision of the geometric shape is not required but that latitude for the shape is within the scope of the disclosure. Furthermore, regardless of whether numerical values or shapes are modified as “about,” “generally,” or “substantially,” it will be understood that these values and shapes should be construed as including a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical values or shapes.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As used herein, “coupled” includes both removably coupled and permanently coupled. For example, when an elastic layer and a support layer are removably coupled to one another, the elastic layer and the support layer can be separated upon the application of sufficient force.
Hardware may be implemented using processing or control circuitry such as, but not limited to, one or more processors, one or more Central Processing Units (CPUs), one or more microcontrollers, one or more arithmetic logic units (ALUs), one or more digital signal processors (DSPs), one or more microcomputers, one or more field programmable gate arrays (FPGAs), one or more System-on-Chips (SoCs), one or more programmable logic units (PLUs), one or more microprocessors, one or more Application Specific Integrated Circuits (ASICs), or any other device or devices capable of responding to and executing instructions in a defined manner.
In some example embodiments, the device 100 may further include a mouthpiece 122. In at least some example embodiments, the mouthpiece 122 may include a first end 124 and a second end 126 opposite the first end 124. The second end 126 of the mouthpiece 122 may be coupled to the second end 112 of the lid 104. In some embodiments, the second end 126 of the mouthpiece 122 may be releasably coupled to the second end 112 of the lid 104.

For example, the diameter or average length/width dimensions of the first end 124 may be smaller than the diameter or average length/width dimensions of the second end 126. Towards the first end 124, the taper may have a slight inward curvature 128 that is configured to receive the lips of an adult consumer and improve the comfort and experience. In some embodiments, the first end 124 may have an oblong or elliptical shape and may include one or more outlets 130. For example, the first end 124 may include four outlets 130, such that four or more different areas or quadrants of the adult consumer's mouth can be engaged during use of the device 100. In other embodiments, the mouthpiece 122 may have fewer outlets than the four outlets 130 or more outlets than the four outlets 130.
In some example embodiments, the housing 102 may include a consumer interface panel 132 disposed on the second side 120 of the device 100. For example, the consumer interface panel 132 may be an oval-shaped panel that runs along the second side 120 of the device 100. The consumer interface panel 132 may include a latch release button 134, as well as a communication screen 136 and/or a control button 138. For example, in at least some example embodiments, the consumer interface panel 132 may include the communication screen 136 disposed between the latch release button 134 and the control button 138. As illustrated, the latch release button 134 may be disposed towards the second end 108 of the device 100, and the control button 138 may be disposed towards the first end 106 of the device 100. The latch release button 134 and the control button 138 may be adult consumer interaction buttons. The latch release button 134 and the control button 138 may have a substantially circular shape with a center depression or dimple configured to direct the pressure applied by the adult consumer, although example embodiments are not limited thereto. The control button 138 may turn on and off the device 100. Though only the two buttons are illustrated, it should be understood more or less buttons may be provided depending on the available features and desired adult consumer interface.
The communication screen 136 may be a user interface such as a human-machine interface (HMI) display. In at least one example embodiment, the communication screen 136 may be an integrated thin-film transistor (“TFT”) screen. In other example embodiments, the communication screen 136 is an organic light emitting diode (“OLED”) or light emitting diode (“LED”) screen. The communication screen 136 is configured for adult consumer engagement and may have a generally oblong shape.
In some embodiments, an exterior of the housing 102 and/or the lid 104 may be formed from a metal (such as aluminum, stainless steel, and the like); an aesthetic, food contact rated plastic (such as, a polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystalline polymer (LCP), a copolyester plastic, or any other suitable polymer and/or plastic); or any combination thereof. The mouthpiece 122 may be similarly formed from a metal (such as aluminum, stainless steel, and the like); an aesthetic, food contact rated plastic (such as, a polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystalline polymer (LCP), a copolyester plastic, or any other suitable polymer and/or plastic); and/or plant-based materials (such as wood, bamboo, and the like). One or more interior surfaces or the housing 102 and/or the lid 104 may be formed from or coated with a high temperature plastic (such as, polyetheretherketone (PEEK), liquid crystal polymer (LCP), or the like).
The lid 104 may be releasably couplable to the housing 102 at the second point 116 by a latch 208, or other similar connector, that allows the lid 104 to be fixed or secured in the closed position and easily releasable to allow the lid 104 to move from the closed position to the open position. In at least one example embodiment, the latch 208 may be coupled to a latch release mechanism disposed within the housing. The latch release mechanism may be configured to move the latch 208 from a first or closed position to a second or open position.
When the lid 104 is in the open position as shown in
As shown in
As discussed herein, an aerosol-forming substrate or a consumable is a material or combination of materials that may yield an aerosol. An aerosol relates to the matter generated or output by the devices disclosed, claimed, and equivalents thereof. The material may include a compound (e.g., nicotine, cannabinoid), wherein an aerosol including the compound is produced when the material is heated. The heating may be below the combustion temperature so as to produce an aerosol without involving a substantial pyrolysis of the aerosol-forming substrate or the substantial generation of combustion byproducts (if any). Thus, in an example embodiment, pyrolysis does not occur during the heating and resulting production of aerosol. In other instances, there may be some pyrolysis and combustion byproducts, but the extent may be considered relatively minor and/or merely incidental.
The aerosol-forming substrate may be a fibrous material. For instance, the fibrous material may be a botanical material. The fibrous material is configured to release a compound when heated. The compound may be a naturally occurring constituent of the fibrous material. For instance, the fibrous material may be plant material such as tobacco, and the compound released may be nicotine. The term “tobacco” includes any tobacco plant material including tobacco leaf, tobacco plug, reconstituted tobacco, compressed tobacco, shaped tobacco, or powder tobacco, and combinations thereof from one or more species of tobacco plants, such as Nicotiana rustica and Nicotiana tabacum.
In some example embodiments, the tobacco material may include material from any member of the genus Nicotiana. In addition, the tobacco material may include a blend of two or more different tobacco varieties. Examples of suitable types of tobacco materials that may be used include, but are not limited to, flue-cured tobacco, Burley tobacco, Dark tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, blends thereof, and the like. The tobacco material may be provided in any suitable form, including, but not limited to, tobacco lamina, processed tobacco materials, such as volume expanded or puffed tobacco, processed tobacco stems, such as cut-rolled or cut-puffed stems, reconstituted tobacco materials, blends thereof, and the like. In some example embodiments, the tobacco material is in the form of a substantially dry tobacco mass. Furthermore, in some instances, the tobacco material may be mixed and/or combined with at least one of propylene glycol, glycerin, sub-combinations thereof, or combinations thereof.
The compound may also be a naturally occurring constituent of a medicinal plant that has a medically-accepted therapeutic effect. For instance, the medicinal plant may be a cannabis plant, and the compound may be a cannabinoid. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for a variety of medicinal purposes (e.g., treatment of pain, nausea, epilepsy, psychiatric disorders). The fibrous material may include the leaf and/or flower material from one or more species of cannabis plants such as Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some instances, the fibrous material is a mixture of 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica.
Examples of cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), while cannabidiolic acid (CBDA) is precursor of cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) may be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, via heating. In an example embodiment, heat from a heater may cause decarboxylation so as to convert the tetrahydrocannabinolic acid (THCA) in the capsule to tetrahydrocannabinol (THC), and/or to convert the cannabidiolic acid (CBDA) in the capsule to cannabidiol (CBD).
In instances where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the capsule, the decarboxylation and resulting conversion will cause a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) during the heating of the capsule. Similarly, in instances where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the capsule, the decarboxylation and resulting conversion will cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of the cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD) during the heating of the capsule.
Furthermore, the compound may be or may additionally include a non-naturally occurring additive that is subsequently introduced into the fibrous material. In one instance, the fibrous material may include at least one of cotton, polyethylene, polyester, rayon, combinations thereof, or the like (e.g., in a form of a gauze). In another instance, the fibrous material may be a cellulose material (e.g., non-tobacco and/or non-cannabis material). In either instance, the compound introduced may include nicotine, cannabinoids, and/or flavorants. The flavorants may be from natural sources, such as plant extracts (e.g., tobacco extract, cannabis extract), and/or artificial sources. In yet another instance, when the fibrous material includes tobacco and/or cannabis, the compound may be or may additionally include one or more flavorants (e.g., menthol, mint, vanilla). Thus, the compound within the aerosol-forming substrate may include naturally occurring constituents and/or non-naturally occurring additives. In this regard, it should be understood that existing levels of the naturally occurring constituents of the aerosol-forming substrate may be increased through supplementation. For example, the existing levels of nicotine in a quantity of tobacco may be increased through supplementation with an extract containing nicotine. Similarly, the existing levels of one or more cannabinoids in a quantity of cannabis may be increased through supplementation with an extract containing such cannabinoids.
The first end cap 217 can include a first opening 218. In some embodiments, the first opening 218 may be a series of openings disposed through the first end cap 217. Similarly, the second end cap can include a second opening that may be a series of openings in some embodiments. In some embodiments, the first end cap 217 and/or the second end cap may be transparent so as to serve as windows configured to permit a viewing of the contents/components (e.g., aerosol-forming substrate and/or heater) within the capsule 214.
The capsule receiving cavity 210 may have a base that may be inside the housing 102. In some embodiments, the base may include at least one contact point that may be configured to couple to one or more contact points of the capsule 214 when the capsule 214 is received by the capsule receiving cavity 210. When the capsule 214 is inserted into the capsule receiving cavity 210, the weight of the capsule 214 itself may not be sufficient to compress the at least one contact point of the base of the capsule receiving cavity 210. As a result, the capsule 214 may simply rest on exposed pins of the at least one contact point without any compression (or without any significant compression) of electrical contacts of the at least one contact point. Additionally, the weight of the lid 104 itself, when pivoted to transition to a closed position, may not compress the electrical contacts of the at least one contact point to any significant degree and, instead, may simply rest on the capsule 214 in an intermediate, partially open/closed position. In such an instance, a deliberate action (e.g., downward force) to close the lid 104 will cause a surface 220 of the lid 104 to press down onto the capsule 214 to provide the desired seal and also cause the capsule 214 to compress and, thus, fully engage the electrical contacts of the at least one contact point.
Additionally, a full closure of the lid 104 may result in an engagement with the latch 208, which may maintain the closed position and the desired mechanical/electrical engagements involving the capsule 214 until released (e.g., via the latch release button 134). The force requirement for closing the lid 104 may help to ensure and/or improve air/aerosol sealing and to provide a more robust electrical connection, as well as improved device and thermal efficiency and battery life by reducing or eliminating early power draws and/or parasitic heating of the capsule 214.
The lid 104 may include an inner cavity 222 that may be adapted to receive the housing 102 when the lid is in the closed position. In some embodiments, the inner cavity 222 of the lid 104 may include an impingement or engagement member or the surface 220 configured to engage the capsule 214 when the lid 104 is pivoted to transition to the closed position. The surface 220 of the lid 104 may include a recess that may correspond to the size and shape of the capsule and/or a resilient material to enhance an interface with the capsule to provide the desired seal. In some embodiments, the lid 104 may further include an opening 224 that may be adapted to receive the second end 126 of the mouthpiece 122. The mouthpiece 122 may include at least one extension 226 that may be received by the opening 224 of the lid 104 to secure the mouthpiece 122 to the lid 104. In some embodiments, the lid 104 may further include a projection that may be configured to couple with a recess 228 of the housing 102. The projection may fit within the recess 228 when the lid 104 is coupled to the housing 102 in the closed position.

The pores 254 in the protective grille 252 may function as inlets for air drawn into the device 100. During the operation of the device 100, ambient air entering through the pores 254 in the protective grille 252 around the charging connector 250 will converge to form a combined flow that then travels to the capsule 214. For example, the pores 254 may be in fluidic communication with the capsule receiving cavity 210. In at least one example embodiment, air may be drawn from the pores 254 and through the capsule receiving cavity 210. For example, air may be drawn through the capsule 214 received by the capsule receiving cavity 210 and out of the mouthpiece 122.

The software may be embodied as program code including instructions for performing and/or controlling any or all operations described herein as being performed by the processor 502.
In other example embodiments, other processing circuitry and/or control circuitry may be used.
The memory 504 is illustrated as being external to the processor 502, in some example embodiments the memory 504 may be on board the processor 502. The memory 504 may describe any of the terms “storage medium”, “computer readable storage medium” or “non-transitory computer readable storage medium” and may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other tangible machine-readable mediums for storing information. The term “computer-readable medium” may include, but is not limited to, portable or fixed storage devices, optical storage devices, and various other mediums capable of storing, containing, or carrying instructions and/or data.
The capsule variable 522 may be a counter that represents the number of capsules used. The capsule variable 522 may be set to zero when the device 100 is new and has not been used by a consumer. The capsule variable 522 may be incremented by one each time that a capsule is detected. A capsule may be detected by the device 100 when the capsule has been heated for at least 10 seconds. In some embodiments, the timer 530 may be started by the processor 502 when the heater 512 is supplied with power. Once the timer 530 reaches ten seconds, the capsule variable 522 may be incremented by one.
The puff variable 524 may be a counter that represents a number of puffs taken. The puff variable 524 may be set to zero when a session ends such that the puff variable 524 may measure the number of puffs taken by a consumer each time a capsule is activated. The puff variable 524 may be incremented by one each time that a puff is detected. A puff may be detected when a consumer applies a negative pressure through the mouthpiece 122 of the device 100 after placing his or her mouth over the mouthpiece 122 of the device 100. In some embodiments, the puff variable 524 may be configured to store the number of puffs taken per capsule and to store an average number of puffs taken per capsule. In some embodiments the processor 502 and/or the memory 504 may be configured to calculate the average number of puffs taken per capsule. In some embodiments, the average number of puffs taken per capsule may be updated each time a capsule is inserted into the device 100 and is activated as described above.
The flight recorder event log 526 may be configured to log events of the device 100. For example, the flight recorder event log 526 may log when the device 100 is plugged into a charger and/or removed from a charger, when the lid 104 is opened and/or closed, when a capsule is inserted into the device 100, when a session is started and/or ended, and when the control button 138 and/or the latch release button 134 is pressed. Additional events that may be recorded in the flight recorder event log 526 are listed in the chart below. In some embodiments, the flight recorder event log 526 may be configured to record over one hundred different interactions with the device 100. The flight recorder event variable 528 may be a counter that represents the number of events listed in the flight recorder event log 526.

In some embodiments, the capsule variable 522, the puff variable 524, the flight recorder event log 526, and the flight recorder event variable 528 may be stored in a local memory that may be part of the memory 504 or the processor 502. In some embodiments, because these metrics are stored in local memory, they will be preserved in the event of a complete battery discharge. Additionally, the capsule variable 522, the puff variable 524, the flight recorder event log 526, and the flight recorder event variable 528 may not be reset to zero unless the device 100 is reset to a factory default state. The device 100 may be reset to a factory default state at a start of a device research session in some embodiments.
The control button 138 may be configured to generate a signal indicating that a consumer has turned the device 100 to an “on” state if the device 100 was previously in an “off” state or to an “off” state if the device 100 was previously in an “on” state. The control button 138 may additionally be pressed as part of a series of interactions with the device 100 to display a message on the communication screen 136. For example, a consumer may press the control button 138 and complete additional interactions with the device 100 to display an indication of engagement with the device 100 on the communication screen 136.
The mechanism detection switch 508 may be configured to generate a signal indicating that a lid mechanism such as the lid 104 of the device 100 has been opened. The mechanism detection switch 508 may be a push button switch, a toggle button, a capacitive sensor, an IR sensor, a magnetic detection sensor such as a Hall Effect sensor, or another element that is configured to communicate with the processor 502 that the lid 104 of the device 100 has been opened. When the lid 104 of the device 100 is opened, any ongoing session of the device 100 may end. The mechanism detection switch 508 may be configured to generate the signal indicating that the lid 104 has been opened when the latch release mechanism of the device 100 releases the latch 208. Additionally or alternatively, the mechanism detection switch 508 may be coupled to the latch release button 134 and may generate the signal indicating that the lid 104 of the device 100 has been opened when the latch release button 134 is pressed. More specifically, the mechanism detection switch 508 may be located within the recess 228 such that closing the lid 104 of the device 100 actuates the mechanism detection switch 508.
In some embodiments, the housing 102 of the device 100 may enclose or house the power supply 510. The power supply 510 may include one or more batteries such as a rechargeable dual battery arrangement, a lithium-ion battery, and/or fuel cells. The power supply 510 may be configured to receive the electric current supplied to the device 100 through the port to charge the power supply 510. The battery monitoring system 520 may generate a signal indicating that the device 100 has entered a low battery state when the power supply 510 reaches a charge that is lower than a predetermined threshold.
The communication screen 136 may display information related to the device 100. The communication screen 136 may display one or more icons to communicate information related to the device 100. For example, the communication screen 136 may display one or more engagement indicator icons. In some embodiments, the engagement indicator icon may be a single digit code or a hex digit code.
The heater 512 may be housed within the device 100 and may be configured to heat the capsule 214 of the device 100. In some embodiments, the heater 512 may be an element of or may be coupled to one or more of a heating voltage measurement circuit, a heating current measurement circuit, and/or a compensation measurement circuit substantially as described in U.S. application Ser. No. 17/151,409 titled “HEAT-NOT-BURN (HNB) AEROSOL-GENERATING DEVICES INCLUDING INTRA-DRAW HEATER CONTROL, AND METHODS OF CONTROLLING A HEATER” filed on Jan. 18, 2021, the disclosure of which is incorporated herein in its entirety by reference.
The airflow sensor 514 may be configured to detect and/or measure characteristics of airflow through the device 100. For example, the airflow sensor 514 may be configured to detect when air is flowing through the device 100. In at least one example embodiment, the airflow sensor 514 may be a microelectromechanical system (MEMS) flow or pressure sensor or another type of sensor configured to measure air flow such as a hot-wire anemometer. In other embodiments, the airflow sensor 514 may be another known sensor. The airflow sensor 514 may be operated as a puff sensor by detecting a draw with a flow value greater than or equal to about 1 mL/s, and terminating a draw when the flow value subsequently drops to about 0 mL/s. In an example embodiment, the airflow sensor 514 may be a MEMS flow sensor based differential pressure sensor with the differential pressure (in Pascals) converted to an instantaneous flow reading (in mL/s) using a curve fitting calibration function or a Look Up Table (of flow values for each differential pressure reading). In another example embodiment, the flow sensor may be a capacitive pressure drop sensor.
In some embodiments, the airflow sensor 514 may be communicatively coupled with the processor 502 such that the processor 502 is configured to measure a length of time that airflow is flowing through the device 100. It should be understood that while it may be stated that the airflow sensor 514 detects a puff, it may be the processor 502 detecting a signal received from the airflow sensor 514 that detects that a puff has been taken. In some embodiments, a puff may be detected when a negative pressure is detected through the mouthpiece 122 of the device 100.
The charging connection 516 may be configured to generate a signal indicating that the device 100 is connected to a charger.

In some embodiments, any of the first nine elements of the hex-digit code 702 may represent the capsule variable 522, the puff variable 524, and the flight recorder event variable 528. Additional or alternatively, the first nine elements of the hex-digit code 702 may be used to encode additional information about the device 100.
In some embodiments, one or more of the elements of the hex-digit code 702 may be or may represent the capsule variable 522. In some embodiments, the element of the hex-digit code 702 that represents the capsule variable 522 may be a scaled or encoded representation of the capsule variable 522 that can be decoded to determine the total number of capsules used by the device 100. In some embodiments, one or more of the elements of the hex-digit code 702 may be or may represent the flight recorder event variable 528. In some embodiments, the element of the hex-digit code 702 that represents the flight recorder event variable 528 may be a scaled or encoded representation of the flight recorder event variable 528 that can be decoded to determine the total number of flight recorder events in the flight recorder event log 526. In some embodiments, one or more of the elements of the hex-digit code 702 may be or may represent an average number of puffs taken per capsule represented by the puff variable 524. In some embodiments, the element of the hex-digit code 702 that represents the puff variable 524 may be a scaled or encoded representation of the puff variable 524 that can be decoded to determine the average number of puffs taken per capsule.
In some embodiments, one or more of the elements of the hex-digit code 702 may be a data integrity check value such as a checksum. In some embodiments, the data integrity check value may be a binary value that may indicate whether the data is of good quality. If the data is corrupt, the data may not be considered good quality or there may be an issue with one or more metrics being measured by the engagement indicator system 500. In other embodiments, the data integrity check value may be encoded into more than one element of the hex-digit code 702. The data integrity check or the checksum may be a data redundancy check that may be used as a pass/fail feature to determine if a consumer has interpreted and/or read the hex-digit code 702 correctly. The checksum may be a standard cycle redundancy check in some embodiments.
In some embodiments, the last element of the hex-digit code may be an overall indicator of engagement with the device 100. The last element may be a number between 1 and 5 where 1 indicates a low level of engagement with the device and 5 indicates a high level of engagement with the device 100. In some embodiments, the last digit of the hex digit code may be the single digit code 602 described above with reference to

In some embodiments, the capsule variable 522, the puff variable 524, and the flight recorder event variable 528 may be packed into a 32-bit word as described above. The capsule variable 522, the puff variable 524, and the flight recorder event variable 528 in this 32-bit word may be XORed with a 28-bit constant “Magic Number” 756 in some embodiments. The bits including the capsule variable 522, the puff variable 524, and the flight recorder event variable 528 may be XORed with the Magic Number 756 to create a cipher. This cipher may obfuscate the fields of bits 4-31 of the 32-bit code. For example, this may help to prevent misinterpretations of the capsule variable 522, the puff variable 524, and the flight recorder event variable 528. Once the capsule variable 522, the puff variable 524, and the flight recorder event variable 528 are XORed with the Magic Number 756, the summary digit 754 may be calculated and added to bits 0-3 of the 40-bit code and then the checksum 752 may be calculated and added to bits 32-39 of the 40-bit code. Once each bit of the 40-bit code is determined, the hex-digit code 702 is determined.
In some embodiments, the hex-digit code 702 may be replaced by a machine-readable code such as a QR code. This machine-readable code may be able to be scanned by a device such as a smartphone that may be configured to interpret and/or display one or more metrics encoded by the machine-readable code. In some embodiments, when the machine-readable code is scanned, the metrics encoded by the machine-readable code may additionally be sent to a research facility or to another remote location such as via email.
In some embodiments, if a consumer uses a number of capsules that is in the twentieth percentile or lower of the consumer data, has a total number of flight recorder events in the twentieth percentile or lower of the consumer data, or takes an average number of puffs per capsule that is in the twentieth percentile or lower of the consumer data, the indication of engagement may be considered low and may be scored a “1”. If a consumer uses a number of capsules that is between the twenty first percentile and the thirty ninth percentile of the consumer data, has a total number of flight recorder events between the twenty first percentile and the thirty ninth percentile of the consumer data, or takes an average number of puffs per capsule that is between the twenty first percentile and the thirty ninth percentile of the consumer data, the indication of engagement may be scored a “2”. If a consumer uses a number of capsules that is between the fortieth percentile and the sixtieth percentile of the consumer data, has a total number of flight recorder events between the fortieth percentile and the sixtieth percentile of the consumer data, or takes an average number of puffs per capsule that is between the fortieth percentile and the sixtieth percentile of the consumer data, the indication of engagement may be considered average and may be scored a “3”. If a consumer uses a number of capsules that is between the sixty first percentile and the seventy ninth percentile of the consumer data, has a total number of flight recorder events between the sixty first percentile and the seventy ninth percentile of the consumer data, or takes an average number of puffs per capsule that is between the sixty first percentile and the seventy ninth percentile of the consumer data, the indication of engagement may be scored a “4”. If a consumer uses a number of capsules that is in the eightieth percentile or above of the consumer data, has a total number of flight recorder events in the eightieth percentile or above of the consumer data, or takes an average number of puffs per capsule that is in the eightieth percentile or above of the consumer data, the indication of engagement may be considered average and may be considered high and may be scored a “5”.
In other embodiments, the percentages may be adjusted, additional metrics may influence the indication of engagement, and/or some metrics may be weighted to have a greater or lesser impact on the indication of engagement with the device 100. For example, in some embodiments, the indication of engagement may be considered low and may be scored a “1” if any of the above described metrics are below the 10th percentile of the consumer data. Additionally, the indication of engagement with the device 100 may be updated and/or adjusted when additional consumer data is acquired. For example, the single digit code 602 and/or the hex-digit code 702 may be adjusted and updated when additional consumer data is acquired.
In some embodiments, the single digit code 602 may be calculated by the processor 502 by the formula: SDC=ROUND((P*0.40)+(C*0.50)+(E*0.1)). SDC may be the single digit code 602, P may be a single digit representation of the average puffs per capsule or the puff variable 524, C may be a single digit representation of the total number of capsules or the capsule variable 522, and E may be a single digit representation of the total number of events logged in the flight recorder event log 526 or the flight recorder event variable 528. As indicated by the formula above, the single digit representation of the average number of puffs per capsule may be given a 40% weight towards the single digit code 602, the single digit representation of the total number of capsules may be weighted 50%, and the single digit representation of the total number of flight recorder events may be weighted 10%.
In some embodiments, the average number of puffs may be given the single digit representation “1” if the average number of puffs per capsule or the puff variable 524 is less than 5. The average number of puffs may be given the single digit representation “2” if the average number of puffs per capsule or the puff variable 524 is less than 8. The average number of puffs may be given the single digit representation “3” if the average number of puffs per capsule or the puff variable 524 is less than 11.75. The average number of puffs may be given the single digit representation “4” if the average number of puffs per capsule or the puff variable 524 is less than 18.25. The average number of puffs may be given the single digit representation “5” if the average number of puffs per capsule or the puff variable 524 is greater than or equal to 18.25.
In some embodiments, the total number of capsules may be given the single digit representation “1” if the total number of capsules or the capsule variable 522 is less than 16. The total number of capsules may be given the single digit representation “2” if the total number of capsules or the capsule variable 522 is less than 25. The total number of capsules may be given the single digit representation “3” if the total number of capsules or the capsule variable 522 is less than 44. The total number of capsules may be given the single digit representation “4” if the total number of capsules or the capsule variable 522 is less than 62. The total number of capsules may be given the single digit representation “5” if the total number of capsules or the capsule variable 522 is greater than or equal to 62.
In some embodiments, the total number of flight recorder events may be given the single digit representation “1” if the total number of flight recorder events or the flight recorder event variable 528 is less than 20000. The total number of flight recorder events may be given the single digit representation “2” if the total number of flight recorder events or the flight recorder event variable 528 is less than 30000. The total number of flight recorder events may be given the single digit representation “3” if the total number of flight recorder events or the flight recorder event variable 528 is less than 50000. The total number of flight recorder events may be given the single digit representation “4” if the total number of flight recorder events or the flight recorder event variable 528 is less than 70000. The total number of flight recorder events may be given the single digit representation “5” if the total number of flight recorder events or the flight recorder event variable 528 is greater than or equal to 70000.
For example, if the puff variable 524 is 9.25, the single digit representation may be “3.” If the capsule variable 522 is 62, the single digit representation may be “5.” If the flight recorder event variable 528 is 65000, the single digit representation may be “4.” Thus, the single digit code 602 may be calculated by the equation SDC=ROUND((3*0.40)+(5*0.50)+(4*0.1)). Thus, the SDC=ROUND(4.10) so the single digit code 602 is “4.”
In some embodiments, there may be an additional final check that is performed by the processor 502 to detect unusual behavior. For example, if the puff variable 524 is less than 3.0 and the capsule variable 522 is greater than 10, the engagement indicator system 500 may override the calculation performed by the processor 502 to determine the single digit code 602 and instead determine that the single digit code 602 is “1.”

In some embodiments, the engagement indicator system 500 may monitor the usage of the device 100 by monitoring at least a number of capsules used, a number of puffs taken, and a number of flight recorder events. The engagement indicator system 500 may monitor these metrics by monitoring the capsule variable 522, the puff variable 524, and the flight recorder event variable 528.
The method 900 may proceed from the step 902 to step 904 to determine an indication of engagement with the device 100. In some examples, the indication of engagement with the device 100 may be an icon that may be displayed on the communication screen 136 by the processor 502. The indication of engagement with the device 100 may be determined based on the metrics that are monitored at the step 902 to monitor the usage of the device 100. In some embodiments, the indication of engagement with the device 100 may be a single digit code representative of an overall engagement with the device 100 such as the single digit code 602. In other embodiments, the indication of engagement with the device 100 may be a hex-digit code such as the hex-digit code 702. Both the single digit code 602 and the hex-digit code 702 may be determined substantially as described above with reference to
After the indication of engagement is determined at the step 904, the method 900 may proceed to step 906 where the processor 502 outputs the indication of engagement determined at the step 904. As described above, the indication of engagement with the device 100 may be an icon such as the single digit code 602 or the hex-digit code 702 that may be output on the communication screen 136 of the device 100.
In some embodiments, the icon may be displayed after a specific interaction with the device 100. For example, the icon may be displayed after the control button 138 is pressed, the lid 104 is opened and closed while the control button 138 is pressed, and the control button 138 is released. In some embodiments, the interaction with the device 100 may be a different sequence of events that may display either the single digit code 602 or the hex-digit code 702 on the communication screen 136.
In some embodiments, the device 100 may be programmed to display either the single digit code or the hex-digit code when the control button 138 is pressed, the lid 104 is opened and closed while the control button 138 is pressed, and the control button 138 is released.

While the control button 138 is depressed, the lid 104 of the device 100 may be opened as represented by arrow 1102. Then the lid 104 of the device 100 may be closed as represented by arrow 1104. The control button 138 may remain depressed while the lid 104 is opened and closed.
After the lid 104 is closed, the control button 138 may be released which may cause an indication of engagement such as the single digit code 602 or the hex-digit code 702 to appear on the communication screen 136 of the device 100. As shown in
In some embodiments, the device 100 can additionally include an irreversible fuse. In some embodiments, the irreversible fuse may be an element of the processor 502 or may be communicatively coupled with the processor 502. When the irreversible fuse is blown, the engagement indicator system 500 may no longer calculate and/or store the capsule variable 522, the puff variable 524, and the flight recorder event variable 528 and may no longer calculate the single digit code 602 or the hex-digit code 702.
The systems, apparatuses, and methods described herein may provide significant advantages. The icon describing an indication of engagement with the device 100 may be displayed by a consumer and may enable real time, accurate feedback about a consumer's engagement with the device 100. The indication of engagement with the device 100 may additionally reduce the burden of in-person interviewing for consumer studies while providing the same or more detailed level of insights into product usage. The indication of engagement with the device 100 may improve consumer studies by providing a quantitative measure of usage of the device 100 which can be used with qualitative statements by consumers to determine a more accurate indication of engagement than without the quantitative measure.
