Definitions
- the present invention relates to a computer implemented method for controlling the operation of an aerosol generation device, an aerosol generation device, a system comprising an aerosol generation device, and a computer readable storage medium.
- the popularity and use of the reduced risk or modified risk smoking devices, also known as electronic cigarettes, vaporizes or aerosol generation devices has grown rapidly in the past few years.
- Such aerosol generation devices provide an alternative to traditional tobacco products such as cigarettes, cigars cigarillos and rolling tobacco. They generally heat or warm an aerosolisable substance to generate an aerosol for inhalation, as opposed to burning tobacco as in traditional tobacco products.
- the aerosol generation device may provide an aerosol either by heating but not burning a solid substrate of tobacco material or by vaporizing a liquid substrate containing a tobacco material or similar.
- an aerosol generation device comprises a battery, a mouthpiece and a heating component that is powered by the battery.
- the battery powers the heating component which heats a solid substrate or vaporizes an e- liquid, generating the aerosol.
- the vaporized aerosol is inhaled by a user.
- the aerosol comprises a suspension of fine solid particles and/or liquid droplets in a gas (typically air).
- cigarettes and other traditional smoking products generate a smoke aerosol that is the result of the combustion of tobacco and contains carbon-based solid particles.
- the carbon-based solid particles in the smoke may be unpleasant to other persons in the vicinity of a user and, due to the smell of the carbon-based solid particles, may affect persons in the vicinity.
- Aerosol i.e. no smoke
- Aerosol generation devices incorporate some form of electronic control circuit, typically including a simple computer processor, allowing a user to control operation of the aerosol generation device.
- This electronic control circuitry may employ short-range wireless communication connections, such as Bluetooth, and send and receive messages from and to a personal computing device, such as a smartphone. This type of connection can be exploited to allow the consumer to control the aerosol generation device in a more sophisticated manner via the personal computing device.
- the document discloses a connection with Bluetooth between an e-cigarette and an application (app) running on a smart phone or other suitable mobile communications device (tablet, laptop, smart watch, etc.).
- the mobile communications device is in one embodiment a GPS enabled mobile phone that receives GPS signals from a sufficient number of satellites to provide a reliable set of GPS coordinates, which are then transmitted to a server, that refers to map data to detect exactly where the mobile communications device is and corrects or confirms the country for which policy alert data is required.
- Policy alert data acquired according to the location of the user provides the user with a summary of any relevant regulatory restriction in relation to vaping within that country (for example minimum age, restrictions relating to indoor/ outdoor vaping, and/ or any social expectations in relation to vaping. However, in case the user chooses to do so, the e-cigarette may continue to be used.
- US 2018/0263283 Ai Another method is disclosed in US 2018/0263283 Ai showing a smartphone in wireless communications with an e-cigarette.
- the smartphone includes an application that may determine the physical location of the smartphone and determines if its user can consume cannabis legally or not.
- a further aerosol generating device and personal computing device is disclosed in US 2015/181945 Ai.
- the document shows a mobile communications device (e.g. a smartphone) which runs a software application that relates to an electronic cigarette and monitors the location of the mobile communication device and thus a location of the electronic cigarette.
- the vapor providing capability of the electronic cigarette 100 is disabled, when the electronic cigarette is deemed to be within a certain distance of a vaping prohibited area whose location is known such as a recorded landmark (e.g. an airport, hospital, restaurant, school, etc.) or a vehicle whose location is tracked (e.g. an airplane, public transit vehicle, rental car, etc.).
- a recorded landmark e.g. an airport, hospital, restaurant, school, etc.
- a vehicle whose location is tracked e.g. an airplane, public transit vehicle, rental car, etc.
- the proposed method has the disadvantage of relying entirely on the mobile phone for making a determination, that the vapor providing capability of the electronic cigarette needs to be disabled.
- a user may circumvent the disabling by disconnecting the aerosol generation device from the mobile communication device. While this may be addressed by disabling the aerosol generation device in general and only allowing a use, when aerosol generation device and communication device are connected, it limits the convenience of use for user unduly, since it is mobile communication device needs to be switched on for using the device.
- the problem of the invention is thus optimizing the data exchange and improving a reactivity of the e-cigarette. Additionally, a further problem of the invention is providing an appropriate level of security.
- the problem is solved with a computer implemented method for controlling operation of an aerosol generation device.
- a context message comprising contextual data about one or more contextual parameters relating to the present context of the aerosol generation device is received.
- the aerosol generation device determines, whether an operation of the aerosol generation device is to be disabled, wherein the determination is at least partially based on the received contextual data. In case the determination is affirmative, the operation of the aerosol generation device is disabled.
- the context message may include an expiration date or period.
- the aerosol generation device is not permanently disabled in case no further context message is received, e.g. in case a connection to the communication device is lost.
- the aerosol generation device is disabled for a prespecified time.
- the context message may comprise a timestamp such that the expiration date or period can be calculated.
- An aerosol generating unit, in particular a heater of the unit, of the aerosol generation device may be disabled, while the aerosol generation device may still be configured to receive further messages. Thereby, a vapor generation is restricted in some areas.
- Contextual data in context messages may be understood as a set of data that can be user specific, geo-localization information, environmental conditions (temperature, humidity, weather) and/or time related.
- context may relate to information related to the possibility to use the device at the current location of the aerosol generation device or the communication device. Thereby, a user might be prevented from being using the device in unauthorized spaces.
- Another application may be contextual data with biometric data such as cardiac pulses or blood pressure.
- the contextual data may be used to activate the aerosol generating device to dispense a particular drug or deactivate the aerosol generation device, if certain thresholds are crossed.
- the contextual data maybe a time of day. This may help a user in regulating his usage behavior.
- aerosol generation devices maybe used to reduce an intake of nicotine gradually and a user may define a computational rule according to which the aerosol generating device is disabled during certain times of the day.
- the contextual data maybe obtained from the internet, i.e. a Webserver that maybe public or private, by the communication device or by the aerosol generation device.
- the communication device or the aerosol generation device for example may comprise sensors or receivers for obtaining user data (i.e. biometric data) and GNSS data.
- One advantage of the invention may be that the usage determination and the decision making process is implemented directly at the aerosol generating device.
- the communication device merely collects the contextual parameters in which the aerosol generation device is operated but that are specific to the aerosol generating device and sends the parameters in a context message to the device, which then determines whether operation of the aerosol generating device is disabled locally. Since the decision is made locally, a more sophisticated approach is provided, and the decisions are more precise.
- the context message might be a broadcast message. Thus, there may not be the need to authenticate or encrypt the message.
- Some contextual data may be protected, for example by encoding. In particular user identification data or biometric data may be encoded.
- the contextual parameters include at least one of: a position of the aerosol generation device or the communication device with which the context message is sent to the aerosol generation device, in particular a GNSS position, user specific data, a consumable profile, a user profile, and environmental data, such as environmental conditions, in particular temperature, humidity, and weather.
- the contextual data includes data specifying areas in which the use of aerosol generation devices is not authorized or permitted.
- the determination, whether an operation of the aerosol generation device is to be disabled is based on a computational rule.
- Example computational rules are unsupervised machine learning algorithms such as clustering analysis, unsupervised decision trees, and supervised machine learning algorithms.
- the computational rule may be received by the aerosol generation device from the communication device.
- the communication device may receive (i.e. download) the computational rule and forward the computational rule to the aerosol generation device.
- the aerosol generation device verifies the received context message using consumer data and/ or consumable data stored on the aerosol generation device.
- the verification includes an authentication with a public key system as shown for example in EP 19189885.7 filed by JT International SA on August 2, 2019.
- the contextual message comprises a set of multiple contextual parameters.
- the aerosol generation device obtains local contextual data from a local storage unit of the aerosol generation device.
- the step of determining, if an operation of the aerosol generation device is to be disabled, is based on both, the contextual data included in the context message and the local contextual data.
- the local contextual data may comprise at least one of: data about past usage of the aerosol generation device, in particular puff records, a consumer identity, consumer settings and device settings. Further examples include event records (e.g. a removal or insertion of consumables, switching the device on and off), and historical decision making records for e.g. supervised machine learning.
- the communication device may transmit a new context message when the communication device detects a change in GNSS position. Particularly preferred, the communication device may transmit a new context message whenever the GNSS position differs from the previous GNSS position by a predetermined threshold. For example, the communication device may send a new context message when the GNSS position has changed at least by 10 m, 50 m or 100 m.
- the aerosol generation device sends a context request for a context message to a communication device.
- the context request is sent in reaction to the aerosol generation device determining that does not have a valid context message, in particular when the expiration date of the most recent context message has passed.
- a communication device obtains of the contextual data and transmits the context message to the aerosol generation device.
- the transmission is performed in reaction to the communication device detecting a change of its position, in particular a change in GNSS information.
- the context message is transmitted wirelessly from the communication device to the aerosol generation device.
- an aerosol generation device is configured to execute the steps according to the method as outlined above.
- a system comprising an aerosol generation device as described above and a communication device is provided, wherein the communication device is configured to execute the steps as outlined above.
- a further aspect of the invention relates to a computer readable storage medium comprising instructions, which when executed cause an aerosol generation device and/or a communication device to carry out the steps of the method as outlined above.

- the consumer profile may indicate whether the user prefers particular tastes, i.e. a stronger or a weaker taste.
- the further database 410 or an additional database could include general contextual data such as types of consumables and their properties.
- the data may indicate preferred temperatures for particular types of consumables, a number of puffs on a particular type of consumable, or similar data.
- the further database 410 or another additional database could include computational rules.
- the computational rules may be forwarded from the personal computing device 104 to the aerosol generation device 102 e.g., wirelessly through Bluetooth communication to allow the aerosol generation device 102 to decide whether operation of the aerosol generation device is to be disabled.
- the personal computing device 104 may also access databases stored on remote server, e.g. a remote server 114 (see figure 1).

- the personal computing device 104 may access the database 402 and compare the location stored on database 402 to its current location or the current location of aerosol generation device 102.
- the areas where the usage of the aerosol generation device is not authorized can include in particular hospitals, airports, museums, public areas (e.g. streets) in which the usage of the aerosol generation devices is forbidden, or similar areas.
- the areas on database 402 are in particular parts on a map and may in a preferred embodiment be stored on a website that could be continuously updated by a service provider.
- the areas on a map where use of the aerosol generation device is not authorized can be similar to no-fly zones for drones or other unmanned aerial vehicles (UAV) where it is crowded with people or regulated by local rules specifically restricting vaping.
- the personal computing device may replicate the database 402 locally in its memory 304 or on one of its storages 306, 308.
- the personal computing device 104 compares its location or the current location of the aerosol generation device 104 and then selects a subset of locations stored in the database 402 that are nearby (i.e.
- database 402 may be accessed and the data aggregated by the software modules operating on the personal computing device 104. Further, the personal computing device 104 may access a further database 404 including contextual data.
- database 404 may include general contextual data, such as the current weather, including temperature, humidity, or similar.
- the personal computing device 104 aggregates the obtained data from the different sources (e.g. geo-localization, internet, web server, storage on personal computing device) in an aggregator 420 into a context message.
- the context message is then forwarded to the communication interface 310 and sent to the aerosol generation device 102 via antenna 312 over the above-mentioned short-range wireless communication.
- the context message may also be provided over a wired communication to the aerosol generation device 102.
- the context message may include the entire data comprised by databases 402, 404,
- the data may be preprocessed or pre-filtered by the personal computing device such that a traffic from the personal computing device to the aerosol generation device is reduced.
- the aerosol generation device 102 receives the context message over the antenna 210 and its communication interface 208. After receipt, the context message is verified and then stored on the aerosol generation device 102 on the memory 204 or on the storage 206. The verification may include an authentication with a key system including a public and a private key or other techniques to verify that the information is transmitted from a previously paired personal computing device. After verification, the context message is forwarded to a microcontroller unit (“MCU”). In addition, local contextual data stored on the aerosol generation device 102 (“local contextual data”) is also forwarded to the MCU. The local contextual data may be stored in database 502, 504 stored on the memory 204 or the storage 206 (see figure 2) of the aerosol generation device 102.
- MCU microcontroller unit
- the database 502 may in particular comprise puff records, event records (i.e. the insertion or removal of consumables) and historical decision-making records.
- the database 502 comprises entries when and where the aerosol generation device 102 was switched on and off and when a puff was taken.
- a second database 504 may include entries on a consumer ID.
- These entries are forwarded as a local context message comprising local contextual data to the MCU.
- the MCU receives the local contextual data and the context message from the personal computing device 104 and decides according to a computational rule, whether a heater is to be disabled.
- the computational rule is in particular based on an unsupervised or supervised machine learning algorithm. For example, the computational rule may compare the consumer ID stored locally on the aerosol generation device (i.e., in the local context message) to a consumer profile (i.e. consumer ID) in the context message received from the personal computing device 104 and determine that the IDs are not identical and disable the heater thereafter. In other words, if another unauthorized person tries to connect another phone to the aerosol generation device and send context messages, the device may consider the received message is from an anonymous sender and disable itself for security protection.
- a particularly preferred embodiment of the invention relates to disabling the heater when the aerosol generation device is in an area, where usage of the aerosol generation device is not authorized.
- the computational rule may compare the GNSS data to the non-authorized areas indicated in the context message and obtained from database 402. In case the MCU determines that the heater is to be disabled, a heater switch command is sent to the heater disabling the heater of the aerosol generation device. Thereupon, the aerosol generation device 102 is unable to generate an aerosol until the heater is enabled again.
- certain substrates may not be consumed depending on the environmental data.
- the computational rule may determine that a humidity or temperature above a certain threshold in combination with a type of consumable may be prevented by disabling the operation of the aerosol generation device 102.
- the computational rule may be stored in a memory or storage of the aerosol generation device. In some embodiments, the computational rule maybe updated. In these cases, the computational rule is forwarded from the personal computing device 104 to the aerosol generation device 102, possibly as part of the context message, preferably however in a separate message. Note that the decision that the aerosol generation device (i.e. the heater) is disabled is made on the aerosol generation device 102 itself. The personal computing device 104 only supplies the data that is relevant for the decision. Thereby, data only needs to be forwarded from web servers and personal communication device to the aerosol generation device. There is a reduced need for data traffic in the upload direction from the aerosol generation device to the personal computing device.
- the aerosol generation device itself enables or disables the heater and also includes the necessary information for the decision, the disablement may not be circumvented by disconnecting aerosol generation device 102 and personal computing device 104.
- the invention hence provides a safer and more reliable mechanism for disabling the aerosol generation device 102 when necessary.
- the aerosol generation device may be entirely disabled. Preferably however, only parts, in particular only an aerosol generation unit, i.e. a heater, is disabled.
- the communication interface as well as the MCU and the user interface 212 may remain active, such that further context messages may be received and such that the device may be switched off.
- a method for disabling the aerosol generation device is shown in the flow chart of figure 6.
- the aerosol generation device receives a context message (S601).
- a computational rule is received from the computing device.
- the aerosol generation device can simply use a computational rule from default setting or received previously and in this case step S602 is not to be performed.
- the computational rule can be updated when there is new context message transmitted to the aerosol generation device, or updated periodically by the manufacturer to update firmware.
- step (S 603) local contextual data is obtained on the aerosol generation device. Note that the order of step S602 and S603 is reversible.
- a proper computational rule can be selected based on the available data, context data received from computing device and/or context data locally stored. Then, according to the computational rule, it is determined, whether an operation of the aerosol generation device is to be disabled on the aerosol generation device (S604). Upon the determination, that the operation is to be disabled, a command is sent to the heating unit of the aerosol generation device that the heating unit is to be disabled (S605).
- the context messages may stay valid as long as no new context message is sent to the aerosol generation device.
- the personal computing device 104 may regularly (i.e. every minute, every 10 minutes, every hour, etc.) send context messages to the aerosol generation device.
- sending of a new context message is triggered by an event. For example, any time a new GNSS location is obtained or the GNSS location differs from the previous GNSS location by a certain (potentially pre-defmed) threshold, a new context message is sent.
- new context messages are sent (and received), when other new contextual parameters are available in any of the databases 402, 404, 408 and 410.
- FIGS. 7 a method of updating the context messages is shown.
- a context message is requested by the aerosol generation device 102.
- the aerosol generation device 102 sends a request for a context message to the personal computing device 104.
- the personal computing device 104 sends the context message to the aerosol generation device 102 in step S702.
- the aerosol generation device 102 verifies, if a message was received (S703) and verifies the message itself in step S704.
- a context message In case no context message was received, another request for a context message (S701) is sent to the personal computing device.
- the validity of the context message is determined. In case the determination is affirmative, the context message is used (S705) as outlined previously for example in figure 6, to enable or disable operation of the aerosol generation device.
- the context message includes an expiration date or an expiration period and the message is used as long as no new context message is received (S705). However, if the context message has expired, a new context message is requested (S701). While the aerosol generation device 102 does not have a valid context message, operation of the aerosol generation device, i.e. operation of the heater, maybe disabled.
