Definitions

  • the present invention relates to smoking substitute devices.
  • it relates to the management of network-enabled smoking substitute devices and their communication with other devices.
  • the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
  • Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
  • the filter typically comprises a filtration material which is circumscribed by a plug wrap.
  • the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
  • a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
  • Such smoking substitute devices can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Smoking substitute devices may comprise electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a "vapour") that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • aerosol also referred to as a "vapour”
  • the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
  • smoking substitute devices are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and tobacco products.
  • Some smoking substitute systems use smoking substitute articles (also referred to as a "consumables”) that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
  • smoking substitute devices are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end. Other smoking substitute devices do not generally resemble a cigarette (for example, the smoking substitute device may have a generally box-like form).
  • a smoking substitute approach corresponds to the manner in which the substitute system operates for a user.
  • vaping in which a vapourisable liquid, typically referred to (and referred to herein) as “e-liquid”, is heated by a heating device to produce an aerosol vapour which is inhaled by a user.
  • An e-liquid typically includes a base liquid as well as nicotine and/or flavourings.
  • the resulting vapour therefore typically contains nicotine and/or flavourings.
  • the base liquid may include propylene glycol and/or vegetable glycerin.
  • a typical vaping smoking substitute device includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating device.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating device.
  • electrical energy is supplied from the power source to the heating device, which heats the e-liquid to produce an aerosol (or "vapour") which is inhaled by a user through the mouthpiece.
  • Vaping smoking substitute devices can be configured in a variety of ways.
  • there are "closed system" vaping smoking substitute devices which typically have a sealed tank and heating element which is pre-filled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute devices include a main body which includes the power source, wherein the main body is configured to be physically and electrically coupled to a consumable including the tank and the heating element. In this way, when the tank of a consumable has been emptied, the main body can be reused by connecting it to a new consumable.
  • Another subset of closed system vaping smoking substitute devices are completely disposable, and intended for one-use only.
  • vaping smoking substitute devices which typically have a tank that is configured to be refilled by a user, so the device can be used multiple times.
  • An example vaping smoking substitute device is the mybluTM e-cigarette.
  • the mybluTM e-cigarette is a closed system device which includes a main body and a consumable.
  • the main body and consumable are physically and electrically coupled together by pushing the consumable into the main body.
  • the main body includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heating device, which for this device is a heating filament coiled around a portion of a wick which is partially immersed in the e-liquid.
  • the device is activated when a microprocessor on board the main body detects a user inhaling through the mouthpiece. When the device is activated, electrical energy is supplied from the power source to the heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • the blu PROTM e-cigarette is an open system device which includes a main body, a (refillable) tank, and a mouthpiece.
  • the main body and tank are physically and electrically coupled together by screwing one to the other.
  • the mouthpiece and refillable tank are physically coupled together by screwing one of the other, and detaching the mouthpiece from the refillable tank allows the tank to be refilled with e-liquid.
  • the device is activated by a button on the main body. When the device is activated, electrical energy is supplied from the power source to a heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • HT Heated Tobacco
  • HNB Heat not burn
  • the tobacco may be leaf tobacco or reconstituted tobacco.
  • the vapour may contain nicotine and/or flavourings.
  • the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
  • a typical HT smoking substitute system may include a device and a consumable.
  • the consumable may include the tobacco material.
  • the device and consumable may be configured to be physically coupled together.
  • heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes components in the tobacco material to be released as vapour.
  • a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) and additionally volatile compounds released from the tobacco.
  • the released vapour may be entrained in the airflow drawn through the tobacco.
  • the vapour passes through the consumable (entrained in the airflow) from the location of vaporisation to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
  • the aerosol will normally contain the volatile compounds.
  • HT smoking substitute systems heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • the IQOSTM smoking substitute device uses a consumable, including reconstituted tobacco located in a wrapper.
  • the consumable includes a holder incorporating a mouthpiece.
  • the consumable may be inserted into a main body that includes a heating device.
  • the heating device has a thermally conductive heating knife which penetrates the reconstituted tobacco of the consumable, when the consumable is inserted into the heating device. Activation of the heating device heats the heating element (in this case a heating knife), which, in turn, heats the tobacco in the consumable.
  • the heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the mouthpiece by the user through inhalation.
  • a second example of the HT approach is the device known as "Glo"TM from British American Tobacco p.l.c. GloTM comprises a relatively thin consumable.
  • the consumable includes leaf tobacco which is heated by a heating device located in a main body. When the consumable is placed in the main body, the tobacco is surrounded by a heating element of the heating device. Activation of the heating device heats the heating element, which, in turn, heats the tobacco in the consumable. The heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the consumable by the user through inhalation.
  • the tobacco when heated by the heating device, is configured to produce vapour when heated rather than when burned (as in a smoking apparatus, e.g. a cigarette).
  • the tobacco may contain high levels of aerosol formers (carrier), such as vegetable glycerine ("VG”) or propylene glycol ("PG").
  • the present inventor(s) have observed that most smoking substitute devices currently on the market are configured to operate in isolation of other devices, which limits the functions the smoking substitute devices can perform.
  • the present inventor(s) have also observed that, as smoking substitute devices become more sophisticated and are able to perform more functions, they may require more sophisticated management. For example, that management may need to consider security and integrity factors for smoking substitute devices that are configured for data acquisition, storage and transmission. In particular, the management of wireless communication of data between smoking substitute devices and mobile devices requires secure and user-controllable management, to ensure accurate, efficient functioning and user peace of mind.
  • the present invention has been devised in light of the above considerations.
  • the present invention provides a system, method and devices, which enable a smoking substitute device to be network-enabled (that is, to be capable of wireless communication with other devices) in a secure and user-controllable manner.
  • the smoking substitute device can be network-enabled in the sense that it can communicate wirelessly, via a wireless network, with the communication terminal of a mobile phone or other device in order to transmit information such as, for example, component status information. Communication can be, for example, over a short-range network.
  • the user can control the transmission of data by initially pairing their smoking substitute device with a first mobile (or "portable") device, for example the user's mobile phone.
  • the pairing can follow a suitable safety protocol.
  • the smoking substitute device and the first mobile device can exchange encryption keys and encrypt the communication link between them.
  • the two devices can be regarded as being “paired”. They may also become “bonded”, wherein they store the encryption keys or other secure identifiers that they exchanged when they paired and use those again the next time they connect.
  • the first mobile device can then act as a central device, or so-called "master controller", wherein the user's smoking substitute device will only be able to communicate with a second mobile device if the first mobile device has granted permission for that line of communication to be established.
  • permission may be granted, for example, by the user inputting a command into an application that is being run on the first mobile device.
  • the command may comprise identifying the second mobile device, thereby enabling it to be added to a so-called "whitelist" of mobile devices that the smoking substitute device is permitted to communicate with.
  • the user may grant such permission to multiple additional mobile devices, each of which should be specifically user-selected and individually paired or bonded to the smoking substitute device.
  • a record or "whitelist" of the devices with which it is permitted to communicate should be stored in a suitable memory means, within the smoking substitute device.
  • the whitelist may also be stored, for example, on the first mobile device and/or within an application.
  • a system for managing a smoking substitute device including: a smoking substitute device; and a first mobile device on which an application is installed.
  • the smoking substitute device has a bonded wireless communication link with the first mobile device.
  • the smoking substitute device is configured to prevent a communication link with a second mobile device from being established unless permitted by the application installed on the first mobile device.
  • the smoking substitute device may be configured to prevent a communication link from being established with the second mobile device in a particular scenario where the second mobile device does not have a bonded wireless communication link with the smoking substitute device.
  • the first mobile device may comprise, for example, a mobile phone, a smart phone, a tablet or a laptop. Bonding of the smoking substitute device to the first mobile device may comprise any suitable steps. For example, it may comprise the sharing of an encryption key, a password or a code between the two devices.
  • the smoking substitute device may be paired to the first mobile device, for example through the exchange of encryption keys, and thereafter it may be bonded to the first mobile device by virtue of the devices storing and remembering the exchanged encryption keys, and re-using those keys each time the devices connect to one another.
  • bonding may comprise the user inputting data to identify the smoking substitute device to the application installed on the first mobile device.
  • the first mobile device can be regarded as being a "master controller", in the sense that any user permissions for permitting communication between the smoking substitute device and any additional mobile devices (including the afore-mentioned second mobile device) need to come from the first mobile device. These permissions may be issued in response to the user providing inputs to the application installed on the first mobile device.
  • the smoking substitute device may be configured to only send advertising wireless communications to the first mobile device, with which it has a bonded communication link, and to any other mobile devices with which has a bonded communication link.
  • the smoking substitute device may be configured to be "invisible" to the second mobile device and to any other devices which it does not have a bonded communication link.
  • the advertising communications issued by the smoking substitute device would be address-specific, for receipt only by bonded devices. So any non-bonded devices would not be able to "see” or receive advertising wireless communications, within a wireless communication network, from the smoking substitute device, once it has been bonded to the first mobile device.
  • the smoking substitute device may be configured to send advertising communications that are visible to a plurality of mobile devices, including the first mobile device to which it is bonded and one or more non-bonded mobile devices, but to ignore or block requests or other communication attempts from all devices except the first mobile device to which it is bonded, unless the first mobile device has issued a specific permission for communication with one or more identified other mobile devices.
  • the smoking substitute device may be configured to begin to wirelessly communicate with the second mobile device, as a result of a permission having been issued by the application installed on the first mobile device. Once it has been given permission to communicate with the smoking substitute device, a second or other additional mobile device may become paired or bonded to the smoking substitute device. Any suitable steps may be followed, for issuing a communication to permit wireless communication between the smoking substitute device and a second mobile device, and for the bonding between them to occur.
  • the steps should preferably include security measures such as the sharing of encryption keys, passwords or codes, to ensure that the smoking substitute only bonds to, and subsequently communicates with, mobile devices that have been specifically identified and authorised by the user.
  • the smoking substitute device may have a memory which stores a so-called "whitelist" configured to identify one or more devices with which the smoking substitute device is permitted to wirelessly communicate.
  • the whitelist may comprise any suitable list, group or record that clearly identifies the permitted devices.
  • the memory may include security means to ensure the whitelist is only accessible to the authorised user of the smoking substitute device, in case the smoking substitute device is lost, borrowed or stolen.
  • the smoking substitute device may be bonded to each of the devices identified on the whitelist.
  • the whitelist may be configured to identify a predetermined maximum number of devices, with which the smoking substitute device is permitted to communicate.
  • the predetermined maximum number of devices may be 10 or fewer.
  • the predetermined maximum number of devices may be 8 or fewer.
  • the smoking substitute device may be configured to automatically connect to any device identified by the whitelist. Therefore, when the user chooses to use a particular mobile device from the whitelist, to connect to the smoking substitute device, the user would not have to go through a pairing or bonding process again, for that mobile device.
  • the smoking substitute device may be configured to wirelessly communicate with the first mobile device via a wireless interface included in the smoking substitute device and a wireless interface included in the first mobile device.
  • a wireless interface included in the smoking substitute device may have BluetoothTM interfaces.
  • other wireless communication networks may be used such as a cellular network (e.g. according to a standard protocol, such as 3G or 4G) or a WiFi network.

  • the method may further comprise issuing a permission, from the application installed on the first mobile device, to permit the smoking substitute device to wirelessly communicate with the second mobile device.
  • the smoking substitute device may comprise a whitelist configured to identify the one or more devices with which the smoking substitute device is permitted to wirelessly communicate.
  • the method may comprise any suitable combination of user-implemented, computer-implemented and hardware-implemented steps. For example, specific user input should be required in order to identify the first mobile device, to which the smoking substitute device should be bonded. Moreover, specific user input should be required in order to identify a second any subsequent mobile devices, for which permission to communicate with the smoking substitute device is to be granted. However, some or all of the steps involved in bonding the smoking substitute device with the mobile device(s), and the subsequent wireless transmissions between the devices, may happen without any specific user input being required. Moreover, the smoking substitute device may be configured such that the storing of data identifying the one or more devices with which the smoking substitute device is permitted to wirelessly communicate, on the whitelist, happens automatically, without any user input.

Thereafter, the device's advertising messages would be directed to all the devices on the whitelist.
  • the master controller mobile device may instruct the smoking substitute device to switch back to being in an "advertising operating mode" and to temporarily advertise to any devices, when it is initiating the process of bonding to a second mobile device, but to accept responses only from the selected additional mobile device(s) to be bonded to it.

  • the size of the predetermined maximum number should also give some scope for the user adding a new mobile device to the permitted list, without necessarily having to delete a pre-existing permitted mobile device (for example, an old device that no longer functions.) It should also give some scope for multiple users to communicate from their mobile devices to a single smoking substitute device.
  • the whitelist should not present a disproportionate burden on the memory or control unit of the smoking substitute device, such that the list should be relatively small. Keeping the list relatively small also enhances the security of the system, by inherently limiting the number of communication permissions that can be granted at a given time, for an individual smoking substitute device.
  • the smoking substitute device may be configured not to send all data to all its bonded mobile devices, at all times. For example, it may be configured to send data just to the master controller mobile device but for that data to be subsequently accessible to the other mobile devices, via the application.

For example, according to an embodiment, the additional/subordinate mobile devices should not be permitted to add further devices to the whitelist, or to remove any devices from the existing whitelist.
  • Certain of the mobile devices on the whitelist may have further restrictions on them, in terms of what instructions they can send to the smoking substitute device and/or on the specific data from the smoking substitute device that they can access. For example, there may be a restricted permission for some devices, wherein they can use the application to look at, for example, tank fill level data for the smoking substitute device but they cannot access usage data.

  • the application may be configured to set a flag in the smoking substitute device, to prohibit communication with other devices that are not in the whitelist, even if the smoking substitute device is "visible", i.e. receptive to inquiry, from such devices.
  • the specific embodiments described herein involve establishing "bonded" communication links, in which the devices store the exchanged encryption keys, and use them again for future connection, it may be possible for one or more "paired" communication links to be formed instead, between the smoking substitute device and a mobile device.
  • the devices exchange encryption keys or other authorisation data, in order to establish a secure communication link therebetween, but they do not store the encryption keys for re-use in future.
  • the application and/or the smoking substitute device may be configured to implement a protocol for changing the identity of the master controller mobile device, for example if that device is lost or stolen or if the user wishes to "upgrade" to a new or replacement device. If this is done via the application, it should preferably include enough security features (such as ID's, passwords, codes etc) to reduce the risk of the change being made by a non-authorised user. For example, a user may use the application to select another device in the whitelist and input a security code on the newly-selected other device, for example via the application on the other device, to confirm the switch. Alternatively, the user may be able to implement the change via hardware and/or software means within the smoking substitute device itself. Again, any such means should preferably be secure.
