Description

Technical Field

[0001] The present invention relates to an aerosol supply system.

Background Art

[0002] An electronic aerosol supply system such as an e-cigarette generally contains an aerosol generating material such as a reservoir of a raw material liquid containing a formulation typically containing nicotine, or a solid material such as a tobacco-based product, from which an aerosol is generated for inhalation by a user, for example by thermal vaporization. Thus, an aerosol supply system typically comprises an aerosol generator, for example a heating element, arranged to aerosolize a part of the aerosol generating material to generate an aerosol in an aerosol generating region of an air passage through the aerosol supply system. When the user inhales with the device and power is supplied to the aerosol generator, air is drawn into the device through one or more inlet holes and along the air passage to the aerosol generating region. In the aerosol generating region, the air mixes with the vaporized aerosol generator to form a condensed aerosol. The air drawn through the aerosol generating region continues along the air passage to the mouthpiece, carrying a part of the aerosol along, and exits through the mouthpiece for inhalation by the user.

[0003] An aerosol supply system generally comprises a modular assembly which often has two main functional parts, namely an aerosol supply device and a disposable / replaceable consumable part. Typically, the consumable comprises a consumable aerosol generating material and an aerosol generator (heating element), and the aerosol supply device part comprises longer-lived items such as a rechargeable battery, a device control circuit, and user interface features. The aerosol supply device may also be referred to as a reusable part or battery section, and the consumable may also be referred to as a disposable part, cartridge, or cartomizer.

[0004] The aerosol supply device and consumables are mechanically coupled at the interface for use, for example, using threads, bayonet, latch, or friction fitting fasteners. When the aerosol product material of a consumable is depleted, or when the user wishes to switch to a different consumable with a different aerosol generating material, the consumable can be removed from the aerosol supply device and a replacement consumable can be installed in its place.

[0005] A potential drawback of aerosol supply systems is the lack of a means to monitor user usage. This can lead to overuse of the system. Similarly, users may have little understanding of how they are using the system, such as when or how often they are using it.

[0006] This specification describes various techniques that aim to help address or mitigate some of the above-mentioned problems. [Overview of the project]

[0007] This disclosure is provided for in the attached claims.

[0008] An aerosol supply system is provided according to several embodiments described herein. The aerosol supply system comprises an aerosol generator configured to aerosolize an aerosol-generating material. The aerosol supply system also comprises a sensor configured to detect inhalation of the aerosol supply system by a user of the aerosol supply system and to output a corresponding inhalation detection signal to a control circuit. The control circuit is configured to determine, based on the inhalation detection signal, the amount of component delivered to the user from the aerosol-generating material during inhalation, compare the amount of delivered component to a threshold, and provide a notification to the user based on the comparison between the amount of delivered component and the threshold.

[0009] The comparison of the amount of delivered component with a threshold may be based on the amount of component delivered to the user from the aerosol-generating material during each inhalation over a predetermined period (e.g., 1 hour, 24 hours, or 1 week).

[0010] A comparison of the amount of delivered component with a threshold may be performed after each inhalation. Alternatively, a comparison of the amount of delivered component with a threshold may be performed within each inhalation, for example, at predetermined intervals during inhalation.

[0011] The determination of the amount of component delivered to the user from the aerosol-generating material may be based on the concentration of the component in the aerosol-generating material. The component may be nicotine, caffeine, taurine, theine, vitamins, melatonin, or cannabinoids.

[0012] A notification may be provided to the user when the indication of the amount of delivered component exceeds a threshold.

[0013] A notification may be provided to the user based on a comparison between the indicated amount of delivered component and several thresholds.

[0014] The control circuit may be configured to determine a default user action based on an indication of the amount of component delivered to the user from the aerosol-generating material. The default user action may be determined over a single inhalation. The control circuit may be configured to determine the time between inhalations based on an inhalation detection signal and determine the default user action based on the time between inhalations. The default user action may be determined over multiple inhalations, where the time between each of the multiple inhalations is shorter than a predetermined time. The default user action may be determined over a continuous period of time. A threshold may be determined based on the determined default user action.

[0015] Notifications may be provided in applications of aerosol delivery systems and / or remote devices. Notifications may be tactile notifications. Parameters of tactile notifications may be adjustable by the user. Notifications may be configurable by the user.

[0016] A system is provided comprising an aerosol supply system configured to generate an aerosol from an aerosol-generating material, according to some embodiments described herein. The system also comprises a computer configured to determine, based on an inhalation detection signal received from a sensor of the aerosol supply system, an indication of the amount of a component delivered to the user from the aerosol-generating material aerosolized by the aerosol generator during inhalation, compare the indication of the amount of the component to a threshold, and provide a notification to the user based on the comparison between the indication of the amount of the delivered component and the threshold.

[0017] A method for operating several embodiments described herein is provided. This method includes the steps of: receiving an inhalation detection signal from a sensor configured to detect inhalation of the aerosol supply system by a user of the aerosol supply system; determining, based on the inhalation detection signal, an indication of the amount of a component delivered to the user from the aerosol-generating material aerosolized by the aerosol generator during inhalation; comparing the indication of the amount of the component with a threshold; and providing a notification to the user based on the comparison between the indication of the amount of the delivered component and the threshold. A computer-readable storage medium containing instructions is also provided. When these instructions are executed by a processor, the above method is performed.

[0018] These and other aspects will become clear from the detailed description below. In this regard, certain sections of the description should not be read in isolation from other sections.

Mode for Carrying Out the Invention

[0021] In this specification, specific examples, aspects, and features of embodiments are discussed / described. Some aspects and features of the specific examples and embodiments can be implemented as before, and these aspects and features are not discussed / described in detail for the sake of brevity. Therefore, it will be understood that aspects and features of the articles and systems discussed in this specification that are not described in detail can be implemented according to any conventional technique for implementing such aspects and features.

[0022] This disclosure relates to an aerosol supply system, which may also be referred to as an aerosol supply system such as an e-cigarette. Throughout the following description, the terms "e-cigarette" or "electronic cigarette" are sometimes used, but it will be understood that this term may be used synonymously with an aerosol supply system and an electronic aerosol supply system.

[0023] As described above, aerosol supply systems (e-cigarettes) often comprise a modular assembly that includes both a reusable part (the aerosol supply device) and a replaceable (disposable) cartridge part called a consumable. Systems that conform to this type of two-part modular configuration are sometimes generally referred to as two-part systems or devices. Electronic cigarettes also generally have an overall elongated shape. To provide a specific example, certain embodiments of the disclosure described herein include this type of overall elongated two-part system that employs a disposable cartridge. However, it will be understood that the basic principles described herein may be similarly employed in other electronic cigarette configurations, such as modular systems that include more than two parts, as devices adapted to other overall shapes, for example, based on so-called box-mod high-performance devices that typically have a more box-like shape.

[0024] As described above, the present disclosure relates to (but is not limited to) aerosol supply devices and corresponding aerosol supply systems such as e-cigarettes and electronic cigarettes.

[0025] FIG. 1 is a very schematic view (not to scale) of an exemplary aerosol supply system 10, such as an e-cigarette, to which an embodiment is applicable. The aerosol supply system has an overall cylindrical shape and extends along a longitudinal axis or y-axis line as indicated by the axis (however, aspects of the present invention are applicable to e-cigarettes configured in other shapes and configurations), and includes two main components, namely, an aerosol supply device 20 and a consumable 30.

[0026] The consumable 30 is an article containing or consisting of an aerosol generating material 38, and part or all of the article is intended to be consumed by the user during use. The consumable 30 may also comprise one or more other components, such as an aerosol generating material storage area, an aerosol generating material transport component 37, an aerosol generating area, a housing, a wrapper, a mouthpiece 35, a filter, and / or an aerosol modifier.

[0027] The consumable 30 may also include an aerosol generator 36, such as a heating element, which releases heat to cause the aerosol-generating material 38 to generate an aerosol during use. The aerosol generator 36 may include, for example, a flammable material, an electrically conductive material, or a susceptor. It should be noted that the aerosol generator 36 can be part of the aerosol supply device 20, in which case the consumable 30 may include an aerosol-generating material storage area for the aerosol-generating material 38 so that the aerosol-generating material 38 can be moved to the aerosol generator 36 when the consumable 30 is coupled with the aerosol supply device 20.

[0028] The aerosol-generating material 38 is a material that can generate an aerosol when heated, irradiated, or otherwise excited. The aerosol-generating material 38 may or may not contain active substances and / or flavorings, and may be in the form of a solid, liquid, or gel, for example. In some embodiments, the aerosol-generating material 38 may include an "amorphous solid," which is sometimes called a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. The amorphous solid is a solid material that may hold some fluid, such as a liquid, within the amorphous solid. In some embodiments, the aerosol-generating material may include, for example, about 50 wt%, 60 wt%, or 70 wt% amorphous solid to about 90 wt%, 95 wt%, or 100 wt% amorphous solid.

[0029] The aerosol generating material 38 includes one or more active substances and / or flavorings, one or more aerosol former materials, and optionally one or more other functional materials such as pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0030] The active substances used herein may be physiologically active materials. Physiologically active materials are materials intended to achieve or enhance physiological responses. Active substances can be selected from, for example, nutritional supplements, nootropics, and psychoactive agents. Active substances may be of natural origin or obtained synthetically. Active substances may include, for example, nicotine, caffeine, taurine, theine, vitamins such as B6, B12, or C, melatonin, cannabinoids, or their components, derivatives, or combinations. Active substances may also include one or more components, derivatives, or extracts of tobacco, cannabis, or another plant.

[0031] In some embodiments, the active substance includes nicotine. In some embodiments, the active substance includes caffeine, melatonin, or vitamin B12.

[0032] The aerosol supply device 20 includes a power source 14, such as a battery, configured to supply power to the aerosol generator 36. In this example, the power source 14 may be a conventional type, such as a rechargeable battery, commonly used in e-cigarettes or applications requiring a relatively high current supply for a relatively short period of time. The battery 14 can be recharged using a charging port (not shown), which may include, for example, a USB connector.

[0033] The aerosol supply device 20 includes a control circuit 28 configured to monitor and / or control the operation of the aerosol supply system 10 and to provide conventional operating functions in accordance with established techniques for controlling aerosol supply systems such as e-cigarettes. The control circuit (processor circuit) 28 can be thought of to logically include various subunits / circuit elements associated with various aspects of the operation of the e-cigarette. For example, depending on the functions provided in various implementation forms, the control circuit 28 may include a power control circuit for controlling the power supply from the power supply 14 to the aerosol generator 36, a user programming circuit for establishing configuration settings (e.g., user-defined power settings) in response to user input, as well as functions associated with other functional units / circuits in accordance with the principles and aspects of the conventional operation of e-cigarettes described herein. It will be understood that the functions of the control circuit 28 can be provided in various different ways, for example, using one or more appropriately programmed programmable computers and / or one or more appropriately configured application-specific integrated circuits / circuits / chips / chipsets configured to provide the desired functions.

[0034] The aerosol supply device 20 shown in Figure 1 includes one or more air inlets 21. During use, when the user inhales through the mouthpiece 35, air is drawn into the aerosol supply device 20 through the air inlets 21 and along the air passage 23 to the aerosol generator 36. In the aerosol generator 36, the air mixes with vaporized aerosol-generating material 38 to form a condensed aerosol. The air drawn in through the aerosol generator 36 continues along the air passage 23 to the mouthpiece 35, carrying a portion of the aerosol with it, and exits through the mouthpiece 35 for inhalation by the user. One or more air inlets may be formed in the consumable 30 such that the air passage 23 is completely contained within the consumable 30, or it will be understood that the aerosol supply device 20 and the consumable 30 may each contain at least one air inlet 21 and a portion of the air passage 23.

[0035] As a specific example, the consumable 30 includes a housing (e.g., formed from a plastic material), a reservoir formed within the housing to hold an aerosol-generating material 38 (in this example, a liquid which may or may not contain nicotine), an aerosol-generating material transport component 37 (in this example, a wick formed from, for example, glass, cotton fiber, or ceramic material, configured to transport the liquid from the reservoir using capillary action), an aerosol-generating location, and a mouthpiece 35. Although not shown, a filter and / or an aerosol modifier (such as a flavoring material) may be placed in or near the mouthpiece 35. The consumable in this example includes a heater element formed from an electrical resistance material (such as NiCr8020) that is spirally wound around the aerosol-generating material transport component 37 and placed in the air passage 23. The location around the combination of the heating element and the wick is the aerosol-generating location of the consumable 30. The consumables include appropriate electrical contacts for coupling to electrical contacts provided on the aerosol supply device 20 so that power can be supplied directly to the heater element.

[0036] Figure 2 is a schematic diagram of a further example of the aerosol supply system 10, and the same reference numerals are used for similar elements between the aerosol supply system 10 shown in Figure 1 and the aerosol supply system 10 shown in Figure 2.

[0037] The aerosol supply system 10 in Figure 2 includes a sensor 25 configured to detect inhalation of the aerosol supply system 10 by a user of the aerosol supply system 10. For example, the sensor 25 may be a flow sensor, a microphone, a pressure sensor, a light sensor, a touch sensor, an accelerometer, a gyroscope, or any other type of sensor suitable for directly or indirectly detecting or inferring inhalation of the aerosol supply system 10 by a user of the aerosol supply system 10. The sensor 25 shown in Figure 2 is part of the aerosol supply device 20, but is not required. In other embodiments, the sensor 25 may be part of a consumable 30.

[0038] The sensor 25 may be configured to detect inhalation based on one or more of the air inlets 21 or the airflow into the air passage 23 through the aerosol supply system 10. Alternatively, the sensor may include a pressure sensor or optical sensor located on the mouthpiece 35, configured to detect when the user's lips are placed around the mouthpiece 35, or a pressure sensor or optical sensor located on the aerosol supply device 20, to detect when the user places their hands around the aerosol supply device 20.

[0039] In some examples, there are two or more sensors 25. As described above, for example, there may be a sensor 25 placed near the air inlet and another sensor 25 near part of the air passage 23, the aerosol generator 36, and / or the mouthpiece 35. Thus, each sensor is configured to detect inhalation of the aerosol supply system 10. If there are two or more sensors 25, there may be two or more types of sensors, and / or multiple sensors of the same type.

[0040] In response to detection of inhalation of the aerosol supply system 10 by a user of the system, the sensor 25 is configured to output a corresponding inhalation detection signal to the control circuit 28. In some embodiments, the sensor 25 is configured to output an inhalation detection signal continuously or periodically, such as every 0.01 seconds, every 0.1 seconds, or every 1 second. If the sensor 25 outputs an inhalation detection signal periodically, in some implementations the interval between subsequent inhalation detection signals can be set to be less than or equal to the average or typical length of a user's inhalation (e.g., 2-5 seconds), thereby ensuring that inhalation is not missed. In any case, when the sensor 25 detects inhalation of the system, the inhalation detection signal changes. For example, the inhalation detection signal is a binary representation indicating whether inhalation of the system has been detected, for example, "1" indicates that inhalation has been detected and "0" indicates that inhalation has not been detected. Alternatively, the inhalation detection signal may correspond to the inhalation level or intensity detected by the sensor 25. That is, the inhalation detection signal can provide an indication of the inhalation intensity detected by the sensor 25. For example, if the sensor 25 is a microphone or a flow sensor, the inhalation detection signal can provide an indication of the magnitude or intensity of inhalation by the user by providing an indication of the air velocity or mass flow rate through the aerosol supply system 10. In some embodiments, the inhalation detection signal corresponds to the signal detected by the sensor 25. That is, the inhalation detection signal represents the raw output from the sensor 25, which has not been filtered or processed by the sensor 25.

[0041] The inhalation detection signal is set to 0 when no inhalation is detected by the sensor 25, and may correspond to the inhalation level or intensity detected by the sensor 25 when inhalation is detected. In some embodiments, the sensor 25 is configured to output an inhalation detection signal only when inhalation is detected. That is, the sensor 25 is configured to output an inhalation detection signal in response to the detection of inhalation in the system, and the sensor 25 is configured to stop outputting the inhalation detection signal when the sensor 25 no longer detects inhalation.

[0042] Figures 3A to 3C show graphs of the inhalation detection signal output by sensor 25 against time. In the example shown in Figure 3A, sensor 25 continuously outputs an inhalation detection signal, and the inhalation detected by sensor 25 corresponds to the period when the inhalation detection signal is greater than the detection threshold 301. In the example shown in Figure 3B, the inhalation detection signal 305A output by sensor 25 is "0" until time point 302, which corresponds to the time when sensor 25 detects inhalation of the aerosol supply system 10 by the user. This can represent either no inhalation detection signal being output or the inhalation detection signal being output with a value of "0". Between time points 301 and 302, which correspond to the time when sensor 25 detects inhalation of the aerosol supply system 10 by the user, the inhalation detection signal 305B output by sensor 25 is "1". That is, sensor 25 outputs an inhalation detection signal to indicate that inhalation has been detected. After time point 303, the inhalation detection signal 305A output by sensor 25 becomes "0", indicating that sensor 25 no longer detects inhalation. As mentioned above, the above can mean either that there is no inhalation detection signal output, or that the inhalation detection signal is output with a value of "0". In the example shown in Figure 3C, when the sensor 25 does not detect inhalation, the inhalation detection signal 305A is set to "0", and when the sensor 25 detects inhalation, the inhalation detection signal 305C corresponds to the signal recorded by the sensor 25.

[0043] As described above, the sensor 25 is configured to output an inhalation detection signal to the control circuit 28. In response to receiving the inhalation detection signal, the control circuit 28 is configured to determine, based on the inhalation detection signal, the amount of components delivered to the user from the aerosol-generating material during inhalation. As understood, the amount of aerosol delivered to the user during inhalation (broadly interpreted, the amount of aerosol-generating material 38) varies depending on various factors such as the duration of inhalation, the type of aerosol-generating material 38 being aerosolized, the temperature of the aerosol generator 36, the amount of power delivered to the aerosol generator 36, and the velocity or mass flow rate of air passing through the aerosol supply system 10. As described above, the aerosol-generating material 38 contains one or more components. Therefore, the amount of each of the one or more components delivered to the user from the aerosol-generating material 38 during inhalation also varies depending on the amount of aerosol delivered to the user during inhalation. Accordingly, the control circuit is configured to use the inhalation detection signal received from the sensor 25 to determine, based on the inhalation detection signal, the amount of components delivered to the user from the aerosol-generating material during inhalation.

[0044] In some embodiments, the control circuit 28 is configured to determine the duration of inhalation based on the inhalation detection signal received from the sensor 25, and this duration can then be used to determine the indication of the amount of components delivered to the user from the aerosol-generating material 38 during inhalation. In other words, the control circuit 28 can be configured to determine the elapsed time of inhalation based on the inhalation detection signal received from the sensor 25. As previously mentioned, the sensor 25 may be configured to output an inhalation detection signal to the control circuit continuously or periodically. The control circuit is also configured to determine the duration of inhalation by using the changes in these signals, for example, by starting the inhalation timer when the inhalation detection signal changes for the first time and stopping the inhalation timer when the inhalation detection signal changes for the second time. The control circuit 28 can be configured to start the inhalation timer when it receives the first non-zero inhalation detection signal, or when it receives the first inhalation detection signal indicating that inhalation has been detected by the sensor 25, such as at time 302 in Figures 3B and 3C. The control circuit 28 can be configured to stop the inhalation timer when it receives the next zero-value inhalation detection signal, or when it receives the next inhalation detection signal indicating that the sensor 25 has stopped detecting inhalation, such as at time 303 in Figures 3A to 3C. Taking Figures 3A to 3C as an example, the duration of inhalation determined by the control circuit 28 is the elapsed time between time 302 and time 303.

[0045] Alternatively, the duration of inhalation can also be determined based on information contained in the inhalation detection signal, such as a timestamp associated with each inhalation detection signal. For example, in the example shown in Figure 3B or Figure 3C, the control circuit 28 is configured to determine the duration of inhalation using the timestamp of the first non-zero inhalation detection signal received (at time 302) and the timestamp of the next zero-value inhalation detection signal received (at time 303). Alternatively, in the example shown in Figure 3A, the control circuit 28 is configured to determine the duration of inhalation using the timestamp of the first inhalation detection signal received from sensor 25 that exceeds the detection threshold 301, corresponding to time 302 in Figure 3A, and the timestamp of the next inhalation detection signal received from the sensor that does not exceed the detection threshold, corresponding to time 303 in Figure 3A.

[0046] In some embodiments, the control circuit 28 is configured to determine the time between one inhalation and the next inhalation based on the inhalation detection signal. That is, the control circuit 28 is configured to determine the elapsed time from one inhalation to the inhalation following this inhalation. The above can be achieved using the same techniques as above with respect to determining the duration of inhalation, such as using a timer, information contained in the inhalation detection signal, or the duration of the output of the inhalation detection signal.

[0047] The control circuit 28 may also be configured to determine one or more operating parameters of the aerosol supply system 10, which can be used to determine the indication of the amount of components delivered to the user from the aerosol generating material 38 during inhalation. For example, the operating parameter may be the amount of power supplied to the aerosol generator 36 by the power supply 14. In this case, the control circuit 28 is configured to determine the indication of the amount of components delivered to the user from the aerosol generating material 38 during inhalation based on the indication of the amount of power supplied to the aerosol generator 36 by the power supply 14 during inhalation. For example, the indication of the amount of power supplied may be the power delivered to the aerosol generator 36 during inhalation, or the amount of voltage and / or current supplied to the aerosol generator 36 during inhalation, or it may be an integer from 1 to 10, or a power setting of the aerosol generator 36 during inhalation, such as "1" for low values, "2" for intermediate values, and "3" for high values. The amount of aerosol generated by the aerosol generator 36 during inhalation depends on the amount of power supplied to the aerosol generator 36. Therefore, the amount of components delivered to the user from the aerosol-generating material 38 during inhalation can be determined more accurately by taking the amount of power into consideration during calculations.

[0048] Alternatively, or in addition, the control circuit 28 may also determine one or more other operating parameters of the aerosol supply system 10, such as the amount of charge of the power supply 14, the temperature of the aerosol generator 36 or the temperature near the aerosol generator 36, the amount and / or velocity of the airflow through the aerosol supply system 10, and a reading subsequently used to determine the amount of components delivered to the user from the aerosol generating material 38 during inhalation. The operating parameters may change or fluctuate during inhalation (e.g., a decrease in the amount of charge of the power supply 14 or an increase in the temperature of the aerosol generator 36). Therefore, the determination of the operating parameters by the control circuit 28 may correspond to the maximum, minimum, mean, model, or median values ​​of the operating parameters during inhalation. Similarly, the readings of the operating parameters may represent one or more of the values ​​of the operating parameters at the start of inhalation, the values ​​of the operating parameters at the end of inhalation, the maximum value of the operating parameters during inhalation, the minimum value of the operating parameters during inhalation, and the mean, model, and / or median values ​​of the operating parameters during inhalation.

[0049] The determination of the amount of component delivered from the aerosol-generating material 38 may also be based on other factors, such as the concentration of the component in the aerosol-generating material 38. For a given amount of aerosol produced by the aerosol generator 36 from the aerosol-generating material 38, it will be understood that the amount of component in the resulting aerosol will differ depending on the concentration, i.e., the amount of the component in the aerosol-generating material 38. As described above, the component may be an active substance such as nicotine, caffeine, taurine, theine, vitamins such as B6, B12, or C, melatonin, cannabinoids, or their constituents, derivatives, or combinations. The component may also be a flavoring agent, an aerosol former material, or a functional material such as a pH adjuster, colorant, preservative, binder, filler, stabilizer, or antioxidant. Therefore, in order to improve the accuracy of the determination, the concentration of the component in the aerosol-generating material 38 can be considered when determining the amount of component delivered from the aerosol-generating material 38. The concentration of the components in the aerosol-generating material 38 may be provided to the control circuit by the user, for example, by inputting the concentration into a user input device associated with the aerosol supply system 10, or the control circuit 28 may be configured to determine the concentration of the components in the aerosol-generating material 38 in response to, for example, the attachment of a consumable 30 to the aerosol supply system. The consumable 30 may include an electronic chip or tag, such as an RFID tag, that the control circuit 28 can read to determine not only the concentration of the components in the aerosol-generating material 38, but also manufacturer or consumable identification information, one or more flavorings or other components contained in the aerosol-generating material 38, and other characteristics of the consumable, such as the volume or mass of the aerosol-generating material 38 in the consumable 30.

[0050] As described above, the control circuit 28 is configured to determine an indicator of the amount of component delivered. The indicator may represent the actual amount of component delivered, such as the mass or volume of component delivered to the user from the aerosol-generating material 38 during inhalation. For example, the control circuit 28 may be configured to determine the amount of component delivered during inhalation based on the inhalation detection signal, using an algorithm or lookup table. The algorithm or lookup table may be based on empirical data relating to the aerosol delivery system 10, such as the maximum or average mass flow rate of air through the air passage 23, or the amount of component delivered for a standard inhalation profile (referred to as the 55 / 3 / 30 profile), such as 55 ml of air in a 3-second inhalation every 30 seconds. If the amount of component delivered for a standard inhalation profile is known, this amount can be converted using the lookup table or algorithm to determine the amount of component delivered for inhalation in different profiles, such as the duration of inhalation, the volume of aerosol delivered, the amount of power delivered to the aerosol generator 36, and / or the temperature of the aerosol generator 36.

[0051] Alternatively, the indication of the amount of component delivered during inhalation may relate to the amount of component delivered, compared to the volume of the aerosol-generating material storage area, such that the indication of the amount of component delivered indicates the amount of component and / or aerosol-generating material remaining in the aerosol-generating material storage area. For example, the indication may be a percentage of the total amount of aerosol-generating material present in the aerosol-generating material storage area when it is full.

[0052] In some embodiments, the indication of the amount of component delivered during inhalation is evaluated on a fixed scale, such as an integer or real number between 0 and 10 (where 0 is the lowest value and 10 is the highest). However, scales of different forms and particle sizes can also be used. In this case, an indication of 2 represents that a small amount of component was delivered during inhalation, and an indication of 10 represents that the maximum amount of component was delivered. This evaluation can be calculated by multiplying the indication of the operating parameter during inhalation by the duration of inhalation and applying one or more conversion factors, or by any other suitable calculation technique. Using evaluations on such scales allows for comparison between indications from different inhalations without requiring the calculation to be as precise or detailed as when the indication corresponds to the actual amount of component delivered.

[0053] The determination of the amount of component delivered to the user from the aerosol-generating material 38 may occur during the inhalation itself. That is, the control circuit 28 is configured to determine the amount of component delivered while inhalation is taking place, so that the determination is in progress during inhalation. Thus, the determination of the amount of component delivered occurs when an inhalation detection signal is received from the sensor 25. For example, as described above, the control circuit 28 may be configured to initiate the determination of the amount of component delivered in response to receiving an inhalation detection signal from the sensor 25, or in response to a change in the inhalation detection signal received from the sensor 25. In this case, both determinations of the amount of component delivered continue until no more inhalation detection signals are received from the sensor 25, or until the inhalation detection signal received from the sensor 25 changes for the second time. Alternatively, the determination of the amount of component delivered may occur after inhalation is complete.

[0054] The indication of the amount of component delivered during inhalation can be used to determine the indication of the amount of component delivered from the aerosol-generating material 38 to the user during each inhalation over a predetermined period, such as one minute, one hour, one day, one week, or a period longer than one week. For example, the control circuit 28 can be configured to determine the indication of the amount of component delivered during each inhalation over a continuous period. The indications of the amount of component delivered during each inhalation can then be summed up to determine the indication of the total amount of component delivered from the aerosol-generating material 38 to the user over that continuous period. To be understood, a continuous period is intended to mean the time immediately preceding any point in time; for example, a continuous 24-hour period represents the 24-hour period immediately preceding any point in time (i.e., the most recent 24 hours of any point in time). Similarly, the determination can be made over a continuous period of one hour, one day (24 hours), one week (7 days), or other periods.

[0055] Furthermore, the determination of the amount of components delivered to the user from the aerosol-generating material 38 during a predetermined period may also be based on the time between each inhalation during the predetermined period. For some components, the amount of residual components in the user's body tissues decreases over time as the components are absorbed, broken down, excreted, or otherwise depleted from the user's body tissues. By considering the time between each inhalation and the duration of each inhalation during the predetermined period, the determination of the amount of components delivered to the user from the aerosol-generating material 38 during the predetermined period can represent the amount of residual components in the user's body tissues, rather than the amount of components delivered to the user during the predetermined period.

[0056] As can be understood, most users of the aerosol delivery system 10 do not perform a single inhalation with the aerosol delivery system 10, but rather perform a session with the aerosol delivery system 10. A session consists of multiple inhalations over periods of 1-2 minutes, sometimes longer periods of 5 or 10 minutes. Therefore, the control circuit 28 can be configured to determine an indication of the amount of components delivered to the user from the aerosol-generating material 38 over multiple inhalations. The time between each of the multiple inhalations is shorter than a predetermined time. The predetermined time may be set and changed by the user or the control circuit 28, or it may be a fixed value based on empirical data, for example. The predetermined time may be less than 1 minute, 1 minute, 2 minutes, 5 minutes, 10 minutes, or longer than 10 minutes. The predetermined time can be defined as the period of time that continues so that each inhalation within the most recent predetermined period is considered by the control circuit to be part of a session, as described above. Alternatively, the predetermined time may be set so that the time between each inhalation must be shorter than the predetermined time so that the inhalations are considered by the control circuit 28 to be part of the same session. In this case, a session timer can be implemented to determine whether an inhalation is part of a session. The session timer starts when an inhalation detection signal indicates that an inhalation has been detected by the sensor. The session timer also stops when the time between one inhalation and the next exceeds a predetermined time. Alternatively, as described above, a timestamp associated with each inhalation detection signal can be used to determine the amount of components delivered to the user from the aerosol-generating material 38 throughout the session. The determination of the amount of components delivered to the user from the aerosol-generating material 38 during a session may also be based on the inhalation detection signal received for each inhalation during the session, and the time between each inhalation during the session. As described above, this determination can be made for each inhalation in a session. For example, a separate determination may be made during or after each inhalation in a session. Alternatively, the determination may be made once, either during the session or after the entire session has been completed.

[0057] The control circuit 28 is configured to compare the indication of the amount of delivered component with a threshold. The threshold can be set based on the amount of component delivered in a single puff (puff threshold), for example, to correspond to a safe usage limit of the component and / or aerosol-generating material 38, or to a safe usage limit for inhalation of the aerosol-supplying system 10, for example, to prevent one or more of the components of the aerosol-supplying system 10 from overheating or drying out. Alternatively, the threshold can correspond to a session threshold and a daily threshold, which may correspond to a safe usage limit of the component and / or aerosol-generating material, or to a safe usage limit of the aerosol-supplying system for a session and a 24-hour period, respectively. It should be understood that the above refers to a “safe” usage limit, but this does not necessarily refer to the medically approved maximum dose of the component and / or aerosol-generating material 38, but rather to a recommended dose that is slightly below the medically approved maximum dose, for example. Furthermore, the threshold can be adjusted and / or set by the user (either directly or automatically). Therefore, more generally, the threshold represents the amount of component and / or aerosol-generating material 38 over a given period of time (e.g., one inhalation, one minute, one hour, etc.) that is typically below the maximum amount medically approved for that period.

[0058] As described above, the determination of the amount of delivered component may be performed during inhalation. In this case, the comparison of the amount of delivered component with the threshold may be performed continuously or periodically (e.g., every second or every five seconds) during inhalation. That is, the amount of delivered component is always determined during inhalation, and the current value of the amount of delivered component is compared with the threshold. Alternatively, the comparison of the amount of delivered component with the threshold may be performed after each inhalation. In this case, the determination of the amount of delivered component can be performed either during or after inhalation.

[0059] The control circuit 28 is configured to provide notifications to the user based on a comparison between the indicated amount of delivered component and a threshold. For example, notifications can be provided by the aerosol supply system 10 by activating an indicator light, emitting a sound from a speaker, or displaying a message on the display screen of the aerosol supply device 20 and / or consumables 30. Notifications may also be tactile notifications in the aerosol supply system 10, such as vibration or force feedback. For example, vibration can be generated by an eccentric rotating mass (ERM) or piezoelectric actuator in the aerosol supply device 20 and / or consumables 30, or force can be generated by a motor in the aerosol supply device 20 and / or consumables 30. This notification may also be a change in the operating mode of the aerosol supply system 10 that the user will notice, such as stopping, disabling, or otherwise blocking the power supply to the aerosol generator 36. For example, the aerosol generator 36 can be disabled for a certain period of time, such as 5 seconds, 10 seconds, 1 minute, or more than 1 minute.

[0060] Alternatively, or in addition to the above, notifications may also be provided by an application on a remote device. For example, a user of the aerosol supply system 10 may have a remote device that is associated with the aerosol supply system 10 but is separate from the aerosol supply system 10. The control circuit 28 is configured to communicate with this remote device by, for example, Bluetooth®, Bluetooth Low Energy (BLE), ANT+, Wi-Fi, or other suitable wireless communication method. The control circuit 28 may be configured to communicate with the remote device so that notifications are provided to the user on the remote device, such as by an application installed on the remote device. For example, a message may be displayed on the display screen of the remote device, an indicator light may be activated, a sound may be emitted from a speaker, or haptic notification means may be provided to the remote device as described above. The remote device may include any suitable electronic device that can be communicatively coupled with the aerosol supply system 10. For example, the remote device may include a mobile device (such as a smartphone), a PDA, a personal computer, a laptop, a tablet, a smartwatch, etc.

[0061] Furthermore, one or more parameters associated with the notification may be adjusted by the user. For example, the user may adjust the number, brightness, and / or color of the activated indicator lights, the volume, pitch, and / or duration of the sound emitted, and / or the displayed message. The user may also adjust one or more parameters of the haptic notification. For example, the user may adjust the duration, magnitude, and / or pattern of the vibration provided by the actuator or the force provided by the motor.

[0062] This notification may be configurable by the user. That is, the user can adjust one or more parameters associated with the notification in the aerosol supply system 10 and / or the remote device, regardless of whether the notification is provided by the aerosol supply system 10 or by the remote device. For example, even if the notification itself is provided by the aerosol supply system 10, the user can adjust one or more of the parameters associated with the notification using the application of the remote device. For example, the user can disable notifications during inhalation so that they only receive notifications when inhalation is not detected by the sensor 25.

[0063] In some embodiments, the control circuit 28 is configured to provide a notification to the user when the indicator of the amount of component delivered to the user from the aerosol-generating material during inhalation exceeds a threshold. The indicator of the amount of component delivered to the user from the aerosol-generating material during inhalation may represent a percentage of the amount of component delivered to the user from the aerosol-generating material during inhalation, compared to a threshold. For example, the indicator may be a percentage of the threshold, such as 10%, 20%, 50%, 80%, or 110%. The notification is provided to the user when the percentage exceeds 100%. In embodiments where the comparison of the indicator of the amount of delivered component with the threshold is performed during inhalation, the notification may be provided to the user during inhalation as soon as the amount of component delivered to the user from the aerosol-generating material exceeds the puff threshold.

[0064] Alternatively, a notification may be provided to the user when the indicated amount of delivered component is within a threshold range, such as 50%, 75%, or 90% of the threshold. This ensures that the user is notified before the threshold is exceeded. In this case, the notification can indicate to the user how close the indicated amount of delivered component is to the threshold, for example, by displaying a ratio of the value, by visual means such as a progress bar, or by illuminating a certain number of indicator lights on the aerosol supply system or remote device.

[0065] In some embodiments, the aerosol delivery system 10 is configured to display or otherwise communicate to the user the indication of the amount of delivered component. For example, a progress bar may be displayed to the user. The progress bar may be displayed at all times or in response to a user request for this information. However, if the indication of the amount of delivered component is within or exceeds a threshold, the control circuit 28 provides a notification to the user. For example, if 100% represents the threshold and the progress bar is at 90%, the control circuit 28 may provide a notification to the user. This notification may be, for example, a change in display (e.g., the color of the progress bar may change), or a tactile or audible notification may be provided.

[0066] In some embodiments, the control circuit 28 is configured to determine default user behavior based on an indication of the amount of components delivered to the user from the aerosol-generating material 38. That is, the control circuit 28 is configured to detect patterns in one or more inhalations by the user based on an indication of the amount of components delivered to the user from the aerosol-generating material 38. Default user behavior can also be determined from data determined by the control circuit 28 for one or more inhalations, used to generate indications of the amount of components delivered, such as the duration of inhalation, the duration of the session, the time between inhalations, the amount of power delivered to the aerosol generator 36 during inhalation, the power level or setting of the aerosol generator 36 for inhalation, and the type and / or concentration of one or more components in the aerosol-generating material 38. These patterns are then used to set the user behavior to default with respect to the amount of components delivered to the user from the aerosol-generating material 38 during inhalation.

[0067] The default user behavior can be determined over a single inhalation, as is typical for a user's normal inhalation with the aerosol supply system 10. For example, when a user uses the aerosol supply system 10 for the first time, i.e., when only one inhalation is detected, the default user behavior can correspond to the indication of the amount of component delivered for that inhalation. As the user takes more inhalations with the aerosol supply system 10, the default user behavior can be updated based on the indication of the amount of component delivered for each subsequent inhalation, thereby refining the user's normal inhalation with the aerosol supply system 10.

[0068] The amount of ingredient delivered for each inhalation can also be used to determine the default user behavior over a single session. In other words, the default user behavior is determined across multiple inhalations. As described above, the time between each of the multiple inhalations is shorter than a predetermined time. The amount of ingredient delivered for each inhalation can also be used to determine the default user behavior over other periods, such as the continuous period or the continuous 24-hour period, one week, one month, and / or one year.

[0069] Furthermore, the control circuit 28 can continuously update the determined default user behavior based on changes in the indication of the amount of components delivered to the user from the aerosol-generating material 38 over multiple inhalations over time. For example, if the control circuit 28 is configured to determine the time between one inhalation and the next based on the inhalation detection signal, the default user behavior can also be determined based on the time between that inhalation and the next. From the above, for example, if the user takes a series of puffs, the control circuit 28 can detect patterns in the user's behavior, such as whether there are extended periods between sessions, such as 30 minutes, 1 hour, or longer than 1 hour, or whether the user takes a small number of inhalations, such as one or two, but at more regular intervals, such as every 10 or 20 minutes. Similarly, the collected data can enable the control circuit 28 to identify specific times of day when the user takes more inhalations, such as in the morning or evening, or whether the number and duration of inhalations during a session vary throughout the day. For example, a user might have a morning session that includes multiple long inhalations at a high power setting, while an evening session might consist of fewer, shorter inhalations at a lower power setting. A user might perform more inhalations on weekdays, but within a month or a year, data might indicate that the user is performing fewer inhalations, for example, because the user is trying to reduce the use of the aerosol delivery system 10. Such default behavior can be determined based on an indication of the amount of components delivered to the user from the aerosol-generating material 38 for multiple inhalations.

[0070] As described above, for some components, the amount of residual component in the user's body tissue decreases over time as the component is absorbed, broken down, excreted, or otherwise depleted from the user's body tissue. The indication of the amount of component delivered to the user from the aerosol-generating material 38 may indicate the amount of residual component in the user's body tissue over a predetermined period, rather than the amount of component delivered to the user. Therefore, default user behavior may also be based on the amount of residual component in the user's body tissue.

[0071] The control circuit 28 can be configured to determine or change the thresholds based on default user behavior, thereby customizing or otherwise adjusting the operation of the aerosol supply system 10 to suit the user. Alternatively, or in addition, the user can further control the operation of the aerosol supply system 10 by changing one or more of the thresholds, for example, by providing input to the input device of the aerosol supply device 20 or consumable 30, or by using an application of an associated remote device.

[0072] The control circuit 28 can also be configured to change the operating modes of the aerosol supply system 10, such as the amount of power supplied to the aerosol generator 36 by the power supply 14, the temperature of the aerosol generator 36, the sensitivity or detection threshold of the sensor 25, the color and / or number of illuminated light indicators, and / or the volume, pitch and / or duration of the sound emitted by the aerosol supply device 20, based on default user behavior.

[0073] If it is determined that the user will perform a prolonged inhalation, for example, for more than 10 seconds, the control circuit 28 may be configured to change the amount of power supplied to the aerosol generator 36 by the power supply 14 during inhalation in order to prevent the aerosol generator 36 from drying out or overheating. The power supplied to the aerosol generator 36 may be set to an initial value or power setting and then decreased as inhalation continues. Alternatively, if it is determined that the user will perform a very small or mild inhalation, for example, at a low air velocity or mass flow rate, the control circuit 28 may be configured to change the sensitivity or detection threshold of the sensor 25 to ensure that the user's inhalation is properly detected.

[0074] Figure 4 shows a system 400 comprising an aerosol supply system 10 configured to generate aerosols from an aerosol-generating material 38, as described above. The system 400 also includes a computer 40 configured to receive an inhalation detection signal from a sensor 25 and, based on the inhalation detection signal received from the sensor 25 of the aerosol supply system 10, determine the indication of the amount of component delivered to the user from the aerosol-generating material 38 aerosolized by the aerosol generator 36 during inhalation. The computer 40 is also configured to compare the indication of the amount of component with a threshold and to provide a notification to the user based on the comparison between the indication of the amount of delivered component and the threshold.

[0075] As described above and as shown in Figure 4, the computer 40 may be a remote device associated with the user and communicating with the aerosol delivery system 10. Thus, it will be understood that the functions of the control circuit described herein, such as determining the indication of the amount of delivered component, determining default user actions, comparing the indication of the amount of component with a threshold, and providing notifications to the user, can be performed by a computer 40 separate from the aerosol delivery system 10, such as a remote device.

[0076] Figure 5 is a flowchart of a method 500 for determining the amount of component delivered to the user of an aerosol supply system 10. The method begins in step 501, in which an inhalation detection signal is received from a sensor configured to detect inhalation of the aerosol supply system by the user of the aerosol supply system. In step 502, based on the inhalation detection signal, an indication of the amount of component delivered to the user from the aerosol-generating material aerosolized by the aerosol generator during inhalation is determined. In step 503, the indication of the amount of component is compared to a threshold. In step 504, a notification is provided to the user based on the comparison between the indication of the amount of component delivered and the threshold.

[0077] The method 500 shown in Figure 5 can be stored as an instruction in a computer-readable storage medium, and therefore, when the instruction is executed by the processor, the method 500 is executed. The computer-readable storage medium may be non-temporary.

[0078] While the above explains that the indication of the amount of delivered component is compared to a threshold, and then a notification is provided to the user based on the comparison between the indication of the amount of delivered component and the threshold, it should be understood that in some implementations, multiple thresholds (e.g., two) may be provided, and the control circuit 28 is configured to compare the indication of the amount of delivered component with each of the thresholds. For example, if the amount of delivered component exceeds a first amount, a notification can be provided to alert the user that the first level of component has been delivered. If use continues, the amount of delivered component may exceed a second amount, and at that point, a subsequent notification can be provided to alert the user that the second level of component has been delivered. Alternatively, the first and second thresholds can also define a range of delivered component amounts for which no notification is issued. If the amount of delivered component is above or below this range, the control circuit 28 can appropriately provide a notification. In the context of a lower threshold, this lower threshold can be set by the user according to a nicotine withdrawal program, and therefore the notification can provide the user with a message stating that the amount of delivered component is below the threshold. The notification and / or actions performed by the control circuit 28 may be the same or different with respect to the comparison of delivered components compared to different thresholds.

[0079] As described above, this disclosure relates to (but is not limited to) an aerosol supply system comprising an aerosol generator configured to aerosolize an aerosol-generating material. The aerosol supply system also comprises a sensor configured to detect inhalation of the aerosol supply system by a user of the aerosol supply system and to output a corresponding inhalation detection signal to a control circuit. The control circuit is configured to determine, based on the inhalation detection signal, the amount of component delivered to the user from the aerosol-generating material during inhalation, compare the amount of delivered component to a threshold, and provide a notification to the user based on the comparison between the amount of delivered component and the threshold.
