Description

[Technical Field]

[0001] The present disclosure relates to an aerosol generation system, a method of operation for an aerosol generation system, and an aerosol generation device. [Background technology]

[0002] Aerosol-generating systems configured to generate inhalable aerosols from an aerosol-forming substrate are known in the art. Some conventional aerosol-generating systems comprise an aerosol-generating device that can be coupled to an aerosol-generating article. A typical aerosol-generating article for use in an aerosol-generating device comprises an aerosol-forming substrate, and a typical aerosol-generating device comprises a heater assembly including a heating element, the heating element configured to heat the aerosol-forming substrate.

[0003] Typically, in such heated smoking articles, the aerosol is generated by transferring heat from a heat source to a physically separated aerosol-generating substrate or material, which may be located in contact with, within, around, or downstream of the heat source. During use of the aerosol-generating article, volatile compounds are released from the aerosol-generating substrate by heat transfer from the heat source and are entrained in the air drawn through the aerosol-generating article. As the released compounds cool, they condense to form an aerosol. The aerosol may then be inhaled by the user.

[0004] However, the operating requirements and environments for such typical aerosol generating systems vary around the world. It would be advantageous to provide an aerosol generating system that can be adapted to the environmental or geographical requirements of use, thereby allowing the same aerosol generating system to be used by users around the world. For example, high humidity in the environment can cause high humidity in the aerosol-generating article itself. High humidity in the aerosol-generating article can then cause the so-called "hot aerosol" problem, in which undesirably hot aerosol is delivered to the user. Therefore, it is desirable to minimize the "hot aerosol" problem when the aerosol generating system is used in a high-humidity environment. Summary of the Invention

[0005] According to a first aspect of the present disclosure, there is provided an aerosol generation system. The aerosol generation system may include an aerosol generation device. The aerosol generation system may include an external computing device separate from the aerosol generation device. The aerosol generation system may include a position determination device. In particular, the external computing device may include the position determination device.

The position determination device may be configured to output position data indicative of (or responsive to) the position of the aerosol generation system. The aerosol generation system may include a controller. The controller may be configured to control multiple control functions of the aerosol generation system. The multiple control functions of the aerosol generation system may be multiple control functions of the aerosol generation device. That is, the controller may be configurable to implement multiple control functions for controlling the aerosol generation device. The aerosol generation system may be configured to adjust control of at least one of the multiple control functions based on the position of the aerosol generation system determined by the position determination device. The aerosol generation system may be configured to select at least one of the multiple control functions based on the position data. The external computing device may be configured to configure the controller to implement the selected control function.

[0006] Thus, advantageously, the aerosol generating system may be adaptable to the local environment in which it is used. For example, if it is determined that the aerosol generating system is located in an area with high humidity, or where high humidity is common, the functions of the aerosol generating system may be adjusted accordingly. If these functions include heating of the aerosol-forming substrate, such that heating of the aerosol-forming substrate can be adjusted, the likelihood of hot aerosols being delivered to the user, as described above, is minimized. Thus, the same aerosol generating system may be used in different environments without the user experiencing different aerosol effects resulting from the location of the aerosol generating system.

For example, the location data may be in the form of GPS coordinates, and the data derived from the location data may be a country name corresponding to the GPS coordinates.

[0014] The location determination device may determine location data based on a combination of two or more of GPS data, IP address data, and / or data entered by a user via a user interface. The location determination device may determine location data after verifying that at least one of the GPS data, IP address data, and / or data entered by a user via a user interface matches at least one other of the GPS data, IP address data, and / or data entered by a user via a user interface. Advantageously, such a system may minimize the possibility of erroneous determination of the location of the aerosol generation system when one of the GPS data, IP address data, and / or data entered by a user is erroneous.

[0185] 1 shows an aerosol generating device 100. The aerosol generating device 100 comprises an outer housing 102 that can be held by a user when using the aerosol generating device 100.

[0186] The aerosol generating device 100 includes a cavity 120 for receiving an aerosol-generating article 190. The cavity 120 has a distal end 124 and a proximal end 122, where the cavity 120 intersects with the outer housing 102. A heater assembly 130 circumferentially surrounds a portion of the cavity 120. The portion of the cavity is positioned between the distal end 124 and the proximal end 122 of the cavity 120. The heater assembly 130 includes a resistive heating element (not shown) configured to heat the portion of the cavity 120 circumferentially surrounded by the heater assembly 130. This portion of the cavity 120 heated by the heating element is referred to as a heating zone 126.

[0187] The aerosol generating device 100 includes a controller 140. The controller is connected via electrical wiring to the heating element of the heater assembly 130. The controller is also connected via electrical wiring to a rechargeable power source 150 and a computer-readable memory 160.

[0188] The controller 140 is configured to receive location data indicative of the location of the aerosol-generating device or location-dependent data corresponding to the location (or at least an estimated location) of the aerosol-generating device. In particular, the controller 140 is configured to receive location data (or location-dependent data) indicative of the location of the aerosol-generating device from an external computing device. This is described in more detail in FIG. 2. In FIG. 1, the controller 140 includes a Bluetooth interface module, whereby the location data is received by the controller 140 using the Bluetooth interface module. Those skilled in the art will understand that alternative communication modules, such as a Wi-Fi interface module or a wired USB interface module, may be used instead of the Bluetooth interface module.

[0189] 1, the location-dependent data that the controller 140 is configured to receive is firmware. The firmware is loaded into the controller 140. The firmware comprises a number of control functions for controlling the aerosol generating device 100, and one or more programs executable to implement the control functions are stored in the computer-readable memory 160.

[0190] By loading location-dependent firmware into the controller 140, the controller 140 is configured to perform multiple control functions for controlling the aerosol generating device 100 in a manner that is coordinated with its location.

[0191] The first set of control functions are heating profiles for controlling the power supplied by the rechargeable power supply 150 to the heating elements of the heater assembly 130. The heating profiles are stored in the computer-readable memory 160. The heating profiles vary over time the voltage, current, or power supplied from the rechargeable power supply 150 to the heating elements. In FIG. 1 , in response to a user action (e.g., pressing a button or another touch sensor on the device), the controller 140 implements one or more of the heating profiles by controlling the voltage or current supplied from the rechargeable power supply 150 to the heating elements. Firmware loaded into the controller 140 that is selected depending on a location may include a heating profile for that location. The heating profile may be a default heating profile that may be executed in response to a user initiating a heating cycle.

[0192] The rechargeable power source may be (re)charged via an external electrical connector (not shown) exposed through the outer housing 102. A second set of control functions is a charging profile for controlling the power supplied to the rechargeable power source 150 during the recharging process. The charging profile is stored in the computer-readable memory 160. The charging profile varies over time one or both of the voltage and current supplied to the rechargeable power source 150 from the external electrical connector. In FIG. 1 , the controller 140 implements one or more of the charging profiles by controlling one or both of the voltage, current, and power supplied to the rechargeable power source 150 from the external electrical connector. Firmware loaded into the controller 140, which is selected according to a location, may include a charging profile for that location. The charging profile may be a default charging profile that may be executed in response to the external electrical connector providing power to the rechargeable power source 150.

[0193] A third set of control functions is an age verification process. The age verification process is stored in computer-readable memory 160. Controller 140 is configured to control power supplied to the heating element depending on whether a selected age verification process is met. A user may communicate with controller 140 to verify their age using an external computing device, described in more detail in FIG. 2 . Firmware loaded into controller 140, selected depending on the location, may include an age authentication process for that location. The age verification process may be a default age verification process that may be executed in response to a request to unlock the device.

[0194] However, various alternatives to location data indicative of the location of the aerosol-generating device may be used, which may be selected and utilized by those skilled in the art depending on the exact operations and functions performable by controller 140. For example, instead of or in addition to firmware, the location-dependent data may instead include one or more of the following: coordinates, country name, country code, continent name, continent code, region name, region code, temperature, humidity, age threshold, firmware, or a set of IP addresses. In these cases, the plurality of control functions may be predetermined control functions stored in computer-readable memory 160 that may be selected by controller 140 based on location data indicative of the location of the aerosol-generating device received by controller 140.

[0195] The aerosol-generating article 190 is shown detached from the aerosol-generating device 100 and has an elongated cylindrical shape. The aerosol-generating article 190 comprises an aerosol-forming substrate 192 at a first end of the aerosol-generating article 190 and a filter element 196 at a second end of the aerosol-generating article 190 opposite the first end. The aerosol-forming substrate 192 comprises an aggregate of sheets of homogenized tobacco material. However, other types of tobacco-containing substrates, such as tobacco cut filler, can replace the aggregate of sheets of homogenized tobacco material. The filter element 196 comprises a low-density filtration material. The aerosol-generating article 190 comprises a hollow tubular element 194 positioned between the aerosol-forming substrate 192 and the filter element 196. The aerosol-generating article 190 is surrounded by an outer wrapper (not shown).

[0196] Prior to use, the aerosol-generating article 190 is coupled to the aerosol-generating device 100 such that the aerosol-generating article 190 is partially received within the cavity 120. The aerosol-forming substrate 192 is aligned with the heater assembly 130.

[0197] During use, power is supplied to the heating element of the heater assembly 130 so that the aerosol-forming substrate 192 is heated to a temperature at which an aerosol is formed from the aerosol-forming substrate 192. The user sucks on the second end of the aerosol-generating article 190, drawing the generated aerosol through the aerosol-generating article 190 and into the user's mouth.

[0198] During use of the aerosol generating device 100, the controller 140 selects at least one of the heating profiles and at least one of the age verification processes from a plurality of control functions for controlling the aerosol generating device. During charging of the aerosol generating device 100, the controller 140 selects at least one of the charging profiles from a plurality of control functions for controlling the aerosol generating device. The heating profile, selected charging profile, and / or age verification process are selected in response to location data received by the controller 140. For example, if the location data indicates a wet or humid location, the controller 140 selects a wet heating profile as opposed to a dry heating profile. Each heating profile includes a heating element temperature profile and a duty cycle limit profile. The heating element temperature profile is similar between the wet heating profile and the dry heating profile, but the duty cycle limit profile differs between the wet heating profile and the dry heating profile to ensure that the heating element temperature profile is achieved regardless of the system's environmental conditions. Additionally or alternatively, a firmware default heating profile, selected charging profile, and / or age verification process is used. The firmware loaded into the controller 140 is based on the location of the aerosol generating device so that the device operates in a manner specific to that location.

[0199] Figure 2 discloses an aerosol generation system 201. The aerosol generation system 101 comprises an aerosol generation device 200 as shown in Figure 1. As shown in Figure 1, an aerosol-forming article 290 is shown received within a cavity of the aerosol generation device 200.

[0200] The aerosol generation system 201 includes a personal computing device 270, such as a smartphone. The personal computing device 270 includes a personal computing device controller 276. The personal computing device controller 276 communicates with the Bluetooth interface module of the controller 240 using Bluetooth communication signals 241.

[0201] The personal computing device 270 further comprises a position determining device 277. The position determining device 277 is connected via electrical wiring to the personal computing device's controller 276. The position determining device comprises a Global Positioning System (GPS), and the GPS chip communicates with a satellite system 274 via satellite signals 275.

[0202] The position determination device 277 determines the location of the personal computing device using data received from the satellite system 274. Other methods of determining the location of the personal computing device may be used, for example, using the IP address of the personal computing device or the user manually entering the location of the personal computing device using a user interface. Because the personal computing device's controller 276 communicates with the controller's Bluetooth interface module 240 using a relatively short-range Bluetooth communication signal 241, the location of the personal computing device is considered to be the same as the location of the aerosol-generating device 200. This location can therefore be referred to as the location of the aerosol-generating system. The position determination device 277 transmits the location or data indicative of the location of the aerosol-generating system to the personal computing device's controller 276 via electrical wiring.

[0203] The personal computing device controller 276 also communicates with the remote server 272 via a remote server connection 273. The personal computing device controller 276 sends a request to the remote server 272 via the remote server connection 273 depending on the location of the aerosol-generation system. The remote server 272 stores different firmware versions, each firmware version corresponding to a location or range of locations. Following a request from the personal computing device controller 276, the remote server 272 sends the firmware to the personal computing device controller 276 depending on the location of the aerosol-generation system. The personal computing device controller 276 sends the firmware received from the server to the controller 240 via a Bluetooth communication signal 241, which was loaded into the controller 240 as described above.

[0204] Figure 3 shows an aerosol generating device 300. The aerosol generating device 300 is similar to the aerosol generating devices 100, 200 disclosed in Figures 1 and 2, and therefore only the differences will be described.

[0205] The aerosol-generating device 300 itself includes a device positioning device 361. The device positioning device 361 is connected to the controller 340 via electrical wiring. The device positioning device 361 includes a Global Positioning System (GPS), and the GPS chip communicates with the satellite system via satellite signals. However, those skilled in the art will appreciate that alternative positioning devices may be used to determine the location of the aerosol-generating device 300, as discussed above.

[0206] 1 and 2, the heating profile, charging profile, and age verification process are predetermined and stored in computer-readable memory 360. In use, device position determination device 361 receives location data indicating the location of the aerosol-generating device 300 from the GPS chip. Device position determination device 361 then transmits the location data indicating the location of the aerosol-generating device 300 to controller 340. Here, device position determination device 361 transmits GPS coordinate data indicating the location of the aerosol-generating device 300 to controller 340. The controller selects at least one control function from a plurality of predetermined control functions stored in computer-readable memory 360 in response to the GPS coordinate data indicating the location of the aerosol-generating device 300. Again, various alternatives to the location data indicating the location of the aerosol-generating device may be used and can be selected and utilized by those skilled in the art depending on the exact operations and functions performable by the controller. For example, the location data may instead be one or more of a country name, country code or number, a continent name, continent code or number, a region name, region code or number, temperature, humidity, or an age threshold. In these cases, the position-determining device may first compare the GPS coordinate data received from the GPS chip with data stored in computer-readable memory that correlates the GPS coordinate data with one or more of a country name, country code or number, a continent name, continent code or number, a region name, region code or number, temperature, humidity, or an age threshold.

[0207] 4 illustrates a method of operation of an aerosol generation system, the aerosol generation system being the aerosol generation system described with reference to FIG.

[0208] The method includes a first step 401 in which the personal computing device determines the location of the aerosol-generating system using a GPS chip. At 402, data indicative of the location of the aerosol-generating system determined using the GPS chip is output to a controller of the personal computing device. Simultaneously, at 403, the external computing device determines the location of the aerosol-generating system using alternative means, for example, using the IP address of the external computing device. Similarly, at 404, data indicative of the location of the aerosol-generating system, this time determined using the IP address, is output to the personal computing device controller.

[0209] Here, the data indicating the location of the aerosol-generating system, determined using the GPS chip and IP address, output to the controller of the personal computing device is a country code. Various other data categories indicating the location of the aerosol-generating system, including coordinates, country name or country code, continent name or continent code or continent code, or region name or region code or region code, may be used instead of the country code.

[0210] The method then includes comparing data indicative of the location of the aerosol-generating system determined using the GPS chip with data indicative of the location of the aerosol-generating system determined using the IP address at 405. If the country code determined using the GPS chip does not match or is not sufficiently similar to the country code determined using the IP address at 406, an error message is displayed to the user on the personal computing device.

[0211] At 407, if the country code determined using the GPS chip matches or is sufficiently similar to the country code determined using the IP address, the controller of the personal computing device sends a request to a remote server over an Internet connection, the request depending on the country code. The remote server then sends personal computing device controller firmware over the Internet connection, the firmware depending on the request from the personal computing device controller, at 408. After receiving the firmware from the remote server, the controller of the personal computing device sends the firmware to the aerosol generating device controller, where the firmware is loaded into the aerosol generating device controller, at 409.

[0212] Figure 5 discloses an aerosol generating device 500. The aerosol generating device 500 is similar to the aerosol generating device described with reference to Figures 1 to 3, and therefore only the differences will be described.

[0213] The aerosol-forming article 590 is identical to the aerosol-forming article described with reference to Figures 1 and 2. In Figure 5, the aerosol-forming article 590 is shown received within a cavity of an aerosol generation device 500.

[0214] The aerosol generating device 500 comprises a first acoustic emitter 542 and a first acoustic receiver 543. Both the first acoustic emitter 542 and the first acoustic receiver 543 are connected to the controller 540 via electrical wiring.

[0215] The first acoustic receiver 543 is positioned adjacent to the cavity of the aerosol generating device 500, and the surface of the first acoustic receiver 543 forms part of the inner wall of the cavity. The first acoustic receiver 543 is positioned longitudinally between the heating zone 526 formed by the heater assembly 530 and the proximal end 522 of the cavity.

[0216] A first acoustic emitter 542 is also positioned adjacent to the cavity of the aerosol generating device 500, and the surface of the first acoustic emitter 542 forms part of the interior wall of the cavity. The first acoustic emitter 542 is positioned at the distal end 524 of the cavity.

[0217] Thus, the heating zone 526 formed by the heater assembly 130 is located between the first acoustic emitter 542 and the first acoustic receiver 543 .

[0218] The first acoustic emitter 542 is configured to generate and emit ultrasonic waves having multiple frequencies. When the aerosol-forming article 590 is received in the cavity of the aerosol-generating device 500, the controller 540 sends an electrical signal to the first acoustic emitter 542, causing the first acoustic emitter 542 to generate and emit ultrasonic waves having multiple frequencies. The ultrasonic waves emitted by the first acoustic emitter 542 travel through the aerosol-forming article 590 to the first acoustic receiver 543. The first acoustic receiver 543 is configured to detect the ultrasonic waves having multiple frequencies emitted by the first acoustic emitter 542. The first acoustic receiver 543 sends an electrical signal for each of the multiple frequencies to the controller 540, indicating the magnitude of the ultrasonic waves received by the first acoustic receiver 543.

[0219] In particular, ultrasonic waves emitted by first acoustic emitter 542 travel through the aerosol-forming substrate of aerosol-forming article 590 to first acoustic receiver 543 .

[0220] The sound waves emitted by the first acoustic emitter 542 traveling through the aerosol-forming substrate are thereby attenuated. The sound attenuation level is directly affected by the density, elasticity, and humidity level of the fibrous substrate. For example, fibers become denser and heavier with increasing humidity and water content. Therefore, the humidity of the aerosol-forming substrate can be determined by analyzing the magnitude of the ultrasonic waves detected by the first acoustic receiver 543.

[0221] Thus, the controller 540 calculates the attenuation level of ultrasound waves for each of a plurality of frequencies received by the first acoustic receiver 543 that have traveled through the aerosol-forming substrate.

[0222] The computer-readable memory 560 stores the expected sound attenuation levels of the aerosol-forming substrate for different classifications of aerosol-forming articles for each of a plurality of frequencies, and the expected sound attenuation levels of the aerosol-forming substrate at various levels of humidity for each of the plurality of frequencies.

[0223] The controller 540 compares the calculated attenuation level for each of the plurality of frequencies to the stored attenuation levels and, from this comparison, determines the classification and humidity of the aerosol-forming article 590 received within the aerosol-generating device.

[0224] In a further embodiment, the computer-readable memory 560 may instead store the expected sound attenuation levels of the aerosol-forming substrate for different classifications of the aerosol-forming article for each of a plurality of frequencies. In this case, the humidity of the aerosol-forming substrate 592 of the aerosol-forming article 590 may be determined by the controller 540 using the deviation of the calculated attenuation level from the expected sound attenuation level for the determined classification. For example, greater attenuation than expected for the determined classification may indicate that the aerosol-forming substrate 592 of the aerosol-forming article 590 has a higher humidity.

[0225] The controller 540 controls the operation of the aerosol-generating device 500 in response to the classification and humidity of the aerosol-forming article 590. In particular, the controller 540 controls the power supplied to the heating element of the heater assembly 530 in response to the classification and humidity of the aerosol-forming article 590. The computer-readable memory also stores a plurality of heating profiles. Each heating profile includes at least one power value and an associated length of time. Each heating profile of the plurality of heating profiles is associated with a classification of the aerosol-forming article and a range of humidity values. During use, the controller 540 selects a heating profile from the plurality of heating profiles depending on the classification and humidity of the aerosol-forming article 590 and controls the supply of power from the power source 550 to the heating element of the heater assembly 530 in accordance with the selected heating profile.

[0226] Figure 6 shows an aerosol generation system 601. The aerosol generation system 601 comprises an aerosol generation device 600. The aerosol generation device 600 is similar to the aerosol generation device 500 described with reference to Figure 5, and therefore only the differences will be described.

[0227] The aerosol generation system 601 includes a personal computing device 670, such as a smartphone. The personal computing device 670 includes a personal computing device controller 676. The personal computing device controller 676 communicates with a Bluetooth interface module of the controller 640 using Bluetooth communication signals 641.

[0228] The personal computing device 670 further includes a position determining device 677. The position determining device 677 is connected via electrical wiring to the personal computing device's controller 676. The position determining device includes a Global Positioning System (GPS), and the GPS chip communicates with a satellite system 674 via satellite signals 675.

[0229] The position determination device 677 determines the location of the personal computing device using data received from the satellite system 674. Other methods of determining the location of the personal computing device may be used, for example, using the IP address of the personal computing device or a user manually entering the location of the personal computing device using a user interface. Because the personal computing device's controller 676 communicates with the controller's Bluetooth interface module 640 using a relatively short-range Bluetooth communication signal 641, the location of the personal computing device is considered to be the same as the location of the aerosol-generating device 600. This location can therefore be referred to as the location of the aerosol-generating system. The position determination device 677 transmits the location or data indicative of the location of the aerosol-generating system to the personal computing device's controller 676 via electrical wiring.

[0230] The personal computing device controller 676 also communicates with the remote server 676 via the remote server connection 673. The personal computing device controller 676 sends a request to the remote server 672 via the remote server connection 673 in response to the location of the aerosol-generating system. The remote server 672 contains data such as local temperature and local humidity, each corresponding to a location or range of locations. Following a request from the personal computing device controller 676, the remote server 672 sends the local temperature and local humidity to the personal computing device controller 676 in response to the location of the aerosol-generating system. The personal computing device controller 676 transmits the local temperature and local humidity received from the server to the controller 640 via the Bluetooth communication signal 641.

[0231] The controller 640 controls the operation of the aerosol-generating device 600 in response to the classification and humidity of the aerosol-forming article 690 and data indicative of the location of the aerosol-generating device 600 received from the personal computing device 670. In particular, the controller 640 controls the power supplied to the heating elements of the heater assembly 630 in response to the classification and humidity of the aerosol-forming article 690 and the local temperature and humidity of the location of the aerosol-generating device 600.

[0232] The computer-readable memory 660 includes data correlating the local humidity at the location of the aerosol-generating device 600 with the expected humidity of the aerosol-forming article 690. The controller 640 compares the local humidity at the location of the aerosol-generating device 600 to the data to determine the expected humidity of the aerosol-forming article 690. The controller 640 compares the calculated humidity of the aerosol-forming article 690 with the expected humidity of the aerosol-forming article 690. If the calculated humidity differs significantly from the expected humidity, the controller 640 alerts the user, for example, by activating a warning light (not shown) on the aerosol-generating device. In some embodiments, the data correlating the local humidity at the location of the aerosol-generating device 600 with the expected humidity of the aerosol-forming article 690 may instead be stored on a remote server 672 accessed by a controller 676 of the personal computing device.

[0233] The computer-readable memory 660 also stores a plurality of heating profiles, each of which is associated with a classification of the aerosol-forming article, a range of humidity values, and a range of temperature values. During use, the controller 640 selects a heating profile from the plurality of heating profiles according to the classification, the humidity of the aerosol-forming article 690, and the local temperature, and controls the supply of power from the power source 650 to the heating element of the heater assembly 630 according to the selected heating profile.

[0234] Figure 7 shows an aerosol generation device 700. The aerosol generation device 700 is similar to the aerosol generation device 500 described with reference to Figure 5, and therefore the differences will be mainly described.

[0235] The aerosol generating device 700 includes a first acoustic emitter 745 and a first acoustic receiver 743. Both the first acoustic emitter 745 and the first acoustic receiver 743 are connected to a controller 740 via electrical wiring.

[0236] The first acoustic receiver 743 is positioned adjacent to the cavity of the aerosol generating device 700, and the surface of the first acoustic receiver 743 forms part of the inner wall of the cavity. The first acoustic receiver 743 is positioned longitudinally between the heating zone formed by the heater assembly 730 and the proximal end 722 of the cavity.

[0237] A first acoustic emitter 745 is also positioned adjacent to the cavity of the aerosol generating device 700, with the surface of the first acoustic emitter 742 forming part of the interior wall of the cavity. In contrast to the aerosol generating device described with reference to FIG. 3 , the first acoustic emitter 742 is also positioned longitudinally between the heating zone formed by the heater assembly 730 and the proximal end 722 of the cavity. The first acoustic emitter 745 and the first acoustic receiver 743 are positioned relative to each other on opposite sides of the cavity. Thus, the heating zone 726 formed by the heater assembly 730 is not located between the first acoustic emitter 745 and the first acoustic receiver 743.

[0238] The first acoustic emitter 745 is configured to generate and emit ultrasonic waves having a single frequency. When the aerosol-forming article 790 is received in the cavity of the aerosol-generating device 700, the controller 740 sends an electrical signal to the first acoustic emitter 745, causing the first acoustic emitter 745 to generate and emit ultrasonic waves having a single frequency. The ultrasonic waves emitted by the first acoustic emitter 745 travel through the aerosol-forming article 790, and in particular through the aerosol-forming substrate 792, to the distal end of the cavity 724. The ultrasonic waves are reflected from the surface forming the distal end of the cavity 724 and return through the aerosol-forming substrate 792 to the first acoustic receiver 743.

[0239] The first acoustic receiver 743 is configured to detect ultrasonic waves having a single frequency emitted by the first acoustic emitter 745 and reflected from the surface of the distal end of the cavity. The first acoustic receiver 743 transmits an electrical signal to the controller 740 indicative of the magnitude of the ultrasonic waves received by the first acoustic receiver 743.

[0240] The aerosol-generating device 700 further includes an optical classification sensor 762. The optical classification sensor 762 is positioned adjacent to the cavity of the aerosol-generating device 700, and the surface of the optical classification sensor 762 forms part of the interior wall of the cavity. When the aerosol-forming article 790 is received in the cavity, the optical classification sensor 762 scans a classification indicia, such as a QR code or barcode, printed on the outer surface of the aerosol-forming article 790. The optical classification sensor 762 transmits data indicative of the classification indicia to the controller 740. The controller 740 determines the classification of the aerosol-forming article 790 by comparing the data indicative of the classification indicia with a database stored in the computer-readable memory 760. The database includes a plurality of classifications, each of which is associated with data indicative of a classification indicia.

[0241] The controller 740 controls the operation of the aerosol-generating device 700 depending on the classification of the aerosol-forming article 790 and the humidity of the aerosol-forming article 790, as described in connection with FIG.

[0242] Figure 8 shows an aerosol generation device 800. The aerosol generation device 800 is similar to the aerosol generation device 500 described with reference to Figure 5, and therefore will be described mainly with respect to its differences.

[0243] The aerosol generating device 800 comprises a first acoustic emitter 842, a second acoustic emitter 846, and a first acoustic receiver 843. The first acoustic emitter 842, the second acoustic emitter 846, and the first acoustic receiver 843 are all connected to a controller 840 via electrical wiring.

[0244] The first acoustic receiver 843 is positioned adjacent to the cavity of the aerosol generating device 800, and the surface of the first acoustic receiver 843 forms part of the inner wall of the cavity. The first acoustic receiver 843 is positioned longitudinally between the heating zone formed by the heater assembly 830 and the proximal end 822 of the cavity.

[0245] A first acoustic emitter 842 is also positioned adjacent to the cavity of the aerosol generating device 800, and the surface of the first acoustic emitter 842 forms part of the inner wall of the cavity. The first acoustic emitter 842 is positioned at the distal end 824 of the cavity.

[0246] Thus, the heating zone 826 formed by the heater assembly 830 is located between the first acoustic emitter 842 and the first acoustic receiver 843 .

[0247] A second acoustic emitter 846 is also positioned adjacent to the cavity of the aerosol generating device 800, and the surface of the second acoustic emitter 846 forms part of the interior wall of the cavity. The second acoustic emitter 846 is also positioned longitudinally between the heating zone formed by the heater assembly 830 and the proximal end 822 of the cavity. The second acoustic emitter 846 and the first acoustic receiver 843 are positioned relative to each other on opposite sides of the cavity. Thus, the heating zone 826 formed by the heater assembly 830 is not located between the second acoustic emitter 845 and the first acoustic receiver 843.

[0248] The first acoustic emitter 842 and the second acoustic emitter 846 are configured to generate and emit ultrasonic waves having multiple frequencies. When the aerosol-forming article 890 is received in the cavity of the aerosol-generating device 800, the controller 840 sends an electrical signal to the first acoustic emitter 842, causing the first acoustic emitter 842 and the second acoustic emitter 846 to generate and emit ultrasonic waves having multiple frequencies. The ultrasonic waves emitted by the first acoustic emitter 842 and the second acoustic emitter 846 travel through the aerosol-forming article 890 to the first acoustic receiver 843. The first acoustic receiver 843 is configured to receive the ultrasonic waves having multiple frequencies emitted by the first acoustic emitter 842 and the second acoustic emitter 846. The first acoustic receiver 843 sends an electrical signal for each of the multiple frequencies to the controller 840, indicative of the ultrasonic waves received by the first acoustic receiver 843.

[0249] In particular, ultrasonic waves 844 emitted by the first acoustic emitter 842 travel through the aerosol-forming substrate 892 of the aerosol-forming article 890 to the first acoustic receiver 843. Thus, the humidity of the aerosol-forming substrate 892 can be analyzed.

[0250] Ultrasonic waves 847 emitted by second acoustic emitter 846 travel through aerosol-forming article 890. In particular, ultrasonic waves 847 do not travel through aerosol-forming substrate 892 to first acoustic emitter 843, but instead travel through the hollow acetate tube portion of aerosol-forming article 890.

[0251] Thus, the attenuation experienced by the ultrasonic waves 847 emitted by the second acoustic emitter 846 is different from the attenuation experienced by the ultrasonic waves 844 emitted by the first acoustic emitter 842 .

[0252] The electrical signal received by the controller 840 from the first acoustic receiver 843, indicative of the ultrasonic waves 847 emitted by the second acoustic emitter 846, is used to determine the classification of the aerosol-forming article 890. Different aerosol-forming articles, for example, because the thickness of the hollow acetate tubing section may vary between classifications, result in different amounts of attenuation of the ultrasonic waves 847 emitted by the second acoustic emitter 846. The controller 840 calculates the attenuation level of the ultrasonic waves 847 emitted by the second acoustic emitter 846 and then compares this to the attenuation value stored in the computer-readable memory 860 to determine the classification of the aerosol-forming article 890.

[0253] The electrical signal received by the controller 840 from the first acoustic receiver 843 indicative of the ultrasonic waves 844 emitted by the first acoustic emitter 842 is then used to determine the humidity of the aerosol-forming article 890, and in particular the aerosol-forming substrate 892. The computer-readable memory 860 also stores the expected sound attenuation levels of the aerosol-forming substrate at various levels of humidity for different classifications of aerosol-forming article for each of the multiple frequencies.

[0254] The controller 840 compares the calculated attenuation level of the ultrasonic waves 844 emitted by the second acoustic emitter 842 for each of the multiple frequencies with the stored attenuation levels, and from this comparison determines the humidity of the aerosol-forming article 890 received within the aerosol-generating device.

[0255] FIG. 9 illustrates a method of operating an aerosol generating system. The aerosol generating system is the aerosol generating system described with reference to FIG. 6. The method includes a first step 901 in which an aerosol-forming article is coupled to an aerosol generating device by a user. The method includes determining the classification of the aerosol-forming article coupled to the aerosol generating device, as described in detail with respect to FIGS. 5-8. The method then includes a step 903 in which the classification of the aerosol-forming article is determined to be of a known classification. If the classification of the aerosol-forming article is not of a known classification, such that the computer-readable memory does not have an attenuation value calculated by the controller associated with the known classification, the aerosol generating system determines that the aerosol-forming article is not a suitable aerosol-forming article for aerosol generation. In this case, the aerosol generating system then stops receiving power from the rechargeable power source and displays a warning to the user, for example, a visual indication via an LED on the aerosol generating device.

[0256] If the classification of the aerosol-forming article is of a known classification, then at 906, the humidity of the aerosol-forming article is determined by the controller using at least one acoustic emitter and at least one acoustic receiver, as described in detail with respect to Figures 5-8.

[0257] The aerosol-generation system additionally determines the location of the aerosol-generation system at 907 using the GPS chip of the personal computing device, as described with respect to FIG.

[0258] At 908, the personal computing device obtains data from the server according to the location of the aerosol-generating system, in this example, the local temperature and local humidity at the location of the aerosol-generating system. The personal computing device then transmits the local temperature and local humidity received from the server to the controller via Bluetooth communication signals at 909.

[0259] At 910, the controller controls the operation of the aerosol-generating device in response to the classification and humidity of the aerosol-forming article and data indicative of the location of the aerosol-generating device received from the personal computing device, the exact operation of which is described in detail with respect to FIG.
