[0002] Smoking articles, such as cigarettes and cigars, burn tobacco to produce tobacco smoke during use. Attempts have been made to provide alternatives to these smoking articles that burn tobacco by creating products that release compounds without combustion. An example of such a product is a heating device that releases compounds by heating a material rather than burning it. The material may be, for example, tobacco or other non-tobacco products, which may or may not contain nicotine. Summary of the Invention

[0004] According to a second aspect of the present invention, there is provided an aerosol delivery device comprising a housing, an aerosol generator disposed within the housing, a power source for supplying power to the aerosol delivery device, and a connector for releasably connecting the aerosol delivery device to a user interface module, wherein, during use, when the aerosol delivery device is operably connected to the user interface module, functions that are not available when the aerosol delivery device is operably disconnected from the user interface module are activated in response to input received via the user interface module.

[0005] According to a third aspect of the present invention, there is provided a system comprising an aerosol delivery device and a user interface module according to the first aspect of the present disclosure, wherein the user interface module is configured to be operably connected to the aerosol delivery device, the operable connection being a direct connection with a connector of the aerosol delivery device or a connection with one or more other modules, at least one of which is directly connected to a connector of the aerosol delivery device, and wherein, during use, when the aerosol delivery device is operably connected to the user interface module, functions that are not available when the aerosol delivery device is operably disconnected from the user interface module are activated in response to input received via the user interface module.

[0008] [Detailed explanation] As used herein, the term "aerosol-forming material" includes materials that, upon heating, provide volatile components, typically in the form of an aerosol. Aerosol-forming materials include any tobacco-containing material, such as one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Aerosol-forming materials may also include other non-tobacco products, and some products may or may not contain nicotine. Aerosol-forming materials may be in the form of, for example, a solid, liquid, gel, wax, etc. Aerosol-forming materials may also be, for example, a combination or blend of materials. Aerosol-forming materials are sometimes referred to as "smoking materials."

[0009] Devices are known that heat aerosol-generating material to volatilize at least one component of the aerosol-generating material, typically forming an inhalable aerosol without burning or combusting the aerosol-generating material. Such devices are sometimes referred to as "aerosol delivery devices," "non-combustion heating devices," "tobacco heating product devices," or "tobacco heating devices." Similarly, there are so-called e-cigarette devices, which vaporize aerosol-generating material, typically in liquid form, which may or may not contain nicotine. The aerosol-generating material may be in the form of, or provided as part of, a rod, cartridge, or cassette that can be inserted into the device. An aerosol generator, such as a heater for heating and volatilizing the aerosol-generating material, may be provided as a "permanent" part of the device or may be combined with a replaceable or consumable aerosol-generating material.

[0010] The aerosol delivery device can accept an article containing the aerosol-forming material for heating. An "article" in this context is a component that, during use, includes or contains the aerosol-forming material, which is heated to volatilize the aerosol-forming material and optionally other components during use. A user inserts the article into the aerosol delivery device before it is heated to generate an aerosol, and the user can then inhale the aerosol. The article may, for example, be of a predetermined or specific size configured to be placed within a heating chamber of a device sized to accept the article. Alternatively, the aerosol-forming material can simply be placed in a free or unconstrained manner in an aerosol-generating region, such as the heating chamber of a device; for example, loose-leaf tobacco can be used in this manner.

[0011] As used herein, the term "operably connected" is a connection that allows power and / or data to be transmitted from one module to another module and / or the aerosol delivery device. A module that is "operably connected" to an aerosol delivery device may be directly connected to the aerosol delivery device or may be directly connected to one or more other modules, provided that at least one of the other modules is directly connected to the aerosol delivery device. In such a configuration, all of the connected modules are considered "operably connected" to the aerosol delivery device.

[0012] As used herein, the term "in use" when referring to a module is when the module is operably connected to an aerosol delivery device. The aerosol delivery device does not have to also be in use by a user to generate aerosol for inhalation to be considered operably connected, although this may be the case.

[0013] As used herein, the term "controller" is intended to mean any means capable of controlling the functions of a device. For example, a controller may comprise a simple switch configured to activate and deactivate the supply of power from a power source. Alternatively, a controller may comprise one or more microchips that may be configured to control complex functions of the device. The controller may be configured to allow direct control of the device by a user, or may be configured to automatically control the functions of the device, for example, in response to a user's puffs, or a combination thereof. Remote control of the device is also envisioned.

[0014] As used herein, the term "external device" refers to any device that is not an aerosol delivery device or module according to the present invention.

[0015] In order to improve the user experience during use of an aerosol delivery device, improvements to the device's functionality are continually being promoted. Aerosol delivery devices typically include a very simple user interface, such as a single button interface. The user experience can be improved by including a more complex user interface so that the user has more control over the device's functions. However, adding additional functionality to an aerosol delivery device generally increases at least one of the size, weight, and cost of the device, which is undesirable for users.

[0016] The present disclosure addresses this problem by providing a user interface module connectable to an aerosol delivery device, where the module allows the user more control over the device's functions during use. Providing improved user interaction through the connectable module can improve the user experience while allowing the aerosol delivery device to remain small, lightweight, and inexpensive. Thus, in some situations, a user can choose not to attach the user interface module without losing the ability to use the aerosol delivery device. For example, a user may want to carry the aerosol delivery device in a clothing pocket for a short period of time while traveling, but upon returning to a fixed position, such as sitting at a desk, the user can reattach the user interface module to gain more device functionality.

[0017] A first aspect of the present disclosure defines a user interface module for use with an aerosol delivery device. The user interface module includes a housing and a connector configured to interact with the aerosol delivery device. The connector is configured to form an operable connection between the module and the aerosol delivery device. The user interface module further includes a user interface configured such that, during use, a user can interact with the user interface to control functions of the operably connected aerosol delivery device, thereby providing additional functionality to the aerosol delivery device.

[0018] Forming an operable connection can involve physical engagement of a connector of the module with a connector of either another module or the aerosol delivery device. Such a physical connection may be achieved by the module having one or both male and female portions of a connector, such as a USB Type-C connector. Alternatively, the physical engagement may be achieved by an asexual connection. A physical connection has the advantage of being reliable and simple in design. Additionally, a physical connection may provide the user with the opportunity for tactile feedback, allowing the user to feel and / or see when a physical connection between the module(s) and the aerosol delivery device is made.

[0019] The connector may be configured so that no physical engagement is required. The operable connection may be achieved using, for example, a wireless data connection and / or a wireless power connection. Additionally, the module may be secured to another module and / or the aerosol delivery device using, for example, magnetic forces. A non-physical connection may eliminate the need for an external connector, which has the advantage of reducing the risk of connector damage over the life of the device and simplifying the housing design of both the module and the aerosol delivery device. Additional securing of the module to another module and / or the aerosol delivery device, while not required, may be helpful in maintaining contact between the module and associated components to ensure that the non-physical operable connection between the associated components is reliable.

[0020] A further alternative may be to secure the devices together using physical engagement while achieving an operative connection (ie, data and / or power connection) wirelessly. Such physical engagement may be achieved, for example, by an interference fit between the components or via external engagement members. Physical engagement has the advantage that a user can more easily determine whether a connection has been made between the components, for example, via a tactile signal or simply by being able to visually perceive or feel that a connection has been made. A wireless operative connection eliminates the use of power and / or data connections in the housings of the operatively connected components, thereby simplifying the design and manufacturing requirements of the housing.

[0021] According to a first aspect of the present disclosure, the user interface module is configured such that, during use, the user interface module is operably connected to the aerosol delivery device, either directly or via one or more additional modules. During use, the user interface module provides the user with additional means for controlling the aerosol delivery device. As previously mentioned, this has the advantage that the aerosol delivery device can be simple, small, lightweight, and inexpensive, while allowing the user to control the functions of the aerosol delivery device in addition to easily turning the device on and off.

[0022] Examples of specific functionality that may be included in example user interface modules according to the first aspect of the present disclosure are described in more detail below, and it should be understood that unless otherwise specified, any of the following examples may be combined in a module according to the first aspect of the present disclosure.

[0023] The user interface module may be configured to provide the user with information about the aerosol delivery device. Such information may be, for example, the amount of power remaining in the aerosol delivery device's internal power supply, an estimated number of puffs remaining in the power supply, an estimated number of puffs remaining in a consumable disposed in the device, details of the type of puffs to be taken (e.g., long and spaced apart or short and very frequent), information about the aerosol-generating material of the aerosol delivery device, the identity of the aerosol-generating device, etc. It should be appreciated that many users would find it advantageous to provide the user with more information about the aerosol delivery device and the aerosol-generating material it contains. The information may be provided on a display, such as an LCD screen, or audibly or tactilely, for example, using haptic feedback. Examples of these are described in more detail below.

[0024] The user interface module can include one or more light-emitting diodes (LEDs) configured to, during use, provide a user with information about the operably connected aerosol delivery device and / or information about the user interface module itself. LEDs have the advantage of requiring minimal power to operate. Furthermore, LEDs can be used in a wide range of colors and can be configured or arranged to operate independently at different times; thus, even a small number of LEDs can be configured to provide a user with various types of information by using different illumination sequences.

[0025] The user interface module may include a screen configured to display information to a user. Such a screen may be, for example, a liquid crystal display (LCD). A screen has the advantage of providing a user with more detailed and sophisticated information than is typically possible for a user of other visible user interface components, such as LEDs. It is also expected that the information provided by a screen will generally be clearer and easier for a user to understand than information presented by other means.

[0026] In examples of user interface modules that include a screen, the screen may be a touchscreen configured to further receive user input. Touchscreens have the advantage of being able to both display information and receive user input, thereby allowing for two-way interaction with the aerosol delivery device.

[0027] In another example of a user interface module, the user interface may include one or more of a button, a switch, a dial, and / or a rotary button. Each of these means of interaction is simple, easy for the user to use, and inexpensive to manufacture. Furthermore, each of these user interface components may be configured to both configure the aerosol delivery device and indicate the current configuration to the user. For example, a switch may be configured to toggle the aerosol delivery device between a low-power mode of operation and a high-power mode of operation (the low-power mode and high-power mode refer to the amount of power applied to the aerosol generator of the aerosol delivery device). The position of the switch may also indicate to the user in which of the two modes the aerosol delivery device is currently configured to operate. Similarly, a rotary switch or dial may be used to select from multiple power modes in which the aerosol delivery device can operate and indicate the multiple power modes to the user.

[0028] The user interface module may include a user interface configured to provide audible feedback to the user. Such a user interface may include, for example, a speaker, a buzzer, or a clicker. Providing audible feedback to the user may be advantageous in brightly lit environments where accurately interpreting LEDs or other illuminated feedback means may be difficult. Additionally, audible feedback is advantageous for users who are visually impaired or who otherwise may find visual feedback or indications difficult or distracting to interpret.

[0029] The user interface module can include a user interface configured to provide tactile feedback to a user. Such a user interface can include means for vibrating the device, such as, for example, an asymmetrically weighted wheel attached to an electric motor. Providing tactile feedback to a user is advantageous in situations where the user is unable or unwilling to interpret visual or audible feedback. For example, a user in a brightly lit, noisy environment may have difficulty accurately interpreting the device's illuminating light or the sounds it makes. Haptic feedback is also advantageous in situations where visual or audible information may be inappropriate or distracting to the user or others.

[0030] The user interface module can include a user interface configured to receive audible input. Such a user interface can be, for example, one or more microphones. This allows for "hands-free" operation of the module. This can also allow for "hands-free" control of an operably connected aerosol delivery device during use. This is advantageous when a user is unable or unwilling to operate the module but wishes to input commands. For example, a user may be using an aerosol delivery device with an operably connected user interface module, then put the device down to begin another task and forget to turn the device off. In such a situation, the user can issue a verbal command to the module to instruct the device to stop, thereby eliminating the need to physically interact with the device.

[0031] The user interface module may include a user interface configured to receive tactile input. Such a user interface may be, for example, one or more accelerometers, allowing a user to interact with the device through motion. This may allow, for example, the module and an operably connected aerosol delivery device to be automatically activated when picked up. This may be advantageous because it may allow the device to be switched on more quickly. For example, a user may configure the module such that, when the module is operably connected to the aerosol delivery device, the user's movement of lifting the module automatically activates the aerosol generator of the aerosol delivery device. The inclusion of one or more accelerometers may enable accurate detection of more complex motions. This may allow a user to configure the module to perform various actions in response to specific detected motions.

[0032] The user interface module can include an internal power source. This has the advantage that, during use, the module does not need to be powered by another operably connected device. In situations where the user interface module is operably connected only to the aerosol delivery device, this allows the user interface module to be used without draining the aerosol delivery device's internal power source. This is advantageous because it means that use of the user interface module does not reduce the power available for operation of the aerosol delivery device.

[0033] The internal power source of the user interface module may be a rechargeable battery or a capacitor. The rechargeable battery may be any suitable rechargeable battery, examples of suitable batteries include lithium-ion batteries and nickel-cadmium batteries. Rechargeable power sources, such as rechargeable batteries and capacitors, are advantageous because they can be easily recharged when depleted and can undergo a large number of charge-discharge cycles before needing replacement.

[0034] The internal power supply of the user interface module may be configured to provide power to an operably connected aerosol delivery device or another connected module. This has the advantage that, during use, the user interface module can charge the internal power supply of an operably connected aerosol delivery device or module. A further advantage is that, during use, the operably connected aerosol delivery device can be provided with a very limited internal power supply, thereby further reducing the size, weight, and complexity of the aerosol delivery device.

[0035] The user interface module can include means for wirelessly transmitting power. This can include means for receiving power from an external power source, such as an external wireless charging pad. Alternatively or additionally, the means for wirelessly transmitting power can be configured to transmit power to an additional device external to the housing of the user interface module. The additional device can be another module, an aerosol delivery device, or an external device configured to receive power wirelessly. The user interface module can include two or more means for wirelessly transmitting power so that the user interface module can simultaneously transmit power to or from two or more devices. Wirelessly transmitting power is advantageous because it can eliminate the need for physical connectors on the housing of the user interface module. This can simplify the design and manufacturing requirements of the housing of the user interface module and can also enhance the safety and ease of use of the user interface module. Furthermore, a module including means for wirelessly transmitting and / or receiving power can add such functionality to an operably connected aerosol delivery device without adding size, weight, or cost to the aerosol delivery device.

[0036] The user interface module may include a means for physically connecting the user interface module to an external device. The physical connection may allow power to be provided by the user interface module to or from the external device. The external device may be, for example, a wall outlet, a backup power source such as a battery or another energy storage device, or a plug connected to a cell phone, tablet, or computer. This may allow a user to interact with the user interface module, for example, to adjust preset user preferences, without the user interface module being operably connected to the aerosol delivery device.

[0037] In examples where the user interface module is connected to an external power source, the supplied external power may be directed by the controller to charge at least one of the power sources located within the user interface module, i.e., the internal power source, the power source located within the further operably connected module, and the power source located within the operably connected aerosol delivery device. The user interface module may be configured such that the controller determines the amount of power to be supplied to the module. The user interface module may be further configured such that, if the controller determines that the supplied power is insufficient to charge one or more of the internal power source of the user interface module, the power source of the operably connected module, and the power source located within the operably connected aerosol delivery device, the controller can prioritize the supplied power accordingly. The order in which one or more power sources should be prioritized for charging may be preset or configurable by the user. For example, it may be preferable to charge the power source of the operably connected aerosol delivery device before other power sources. The user interface module may be further configured such that, if the externally supplied power is insufficient to charge either the internal power source of the user interface module or any of the power sources to which the user interface module is operably connected, no power is supplied to any of the power sources. The user interface module may also be configured to alert the user that the externally provided power supply is insufficient to charge one or more of the power sources, and the alert may be a visual, audible, and / or tactile indication. The user interface module may be further configured, when an external power source is connected, to indicate to the user which, if any, of the operably connected power sources are being charged.

[0038] The user interface module may include computer memory located within the housing, which has the advantage that the module can store and maintain information within the computer memory.

[0039] The internal computer memory of the user interaction module may be configured to store and retain user-specific setting information. This may enable a user to use different aerosol delivery devices while retaining the user-specific setting information in the user interface module. For example, a user may have two or more aerosol delivery devices for use with different types of consumables. By retaining user preferences in the internal computer memory, the user interface module may enable a user to quickly and easily configure each device according to previously specified user setting information. This may enable, for example, a user to have a similar session experience across multiple different aerosol delivery devices. For example, the user interface module may provide the same user-specific "end of session" notification (audible, visual, and / or tactile) when the session is reaching its end, regardless of the type of aerosol delivery device being used. Thus, storing user setting information may improve the user experience. In an example of such user-specific setting information, a user may configure the module so that, during use, specific user-defined information is displayed by the user interface module according to their preferences. A user can configure the user interface module to provide visual, audible, and / or tactile feedback during a smoking session, for example, when a consumable is estimated to be nearly depleted. As a further example, a user can specify how certain user interface components of the user interface module can be used to interact with the aerosol delivery device. For example, a user can specify that a particular button or switch be used to activate or deactivate a higher power mode in an operably connected aerosol delivery device. Furthermore, the user interface module may be configured to require a particular user-defined input sequence to unlock or activate the user input module and / or an operably connected device.

[0040] The user interface module may include means for wireless communication with an external device. Examples of possible wireless communication protocols may include Bluetooth, Wi-Fi, cellular network communication, etc. Wireless communication with the external device may enable data transmission between the user interface module and the external device. Such data may include, for example, user-specific settings for the user interface module and / or the operably connected aerosol delivery device. The stored data may also include usage data recorded by the aerosol delivery device, and such data may be used, for example, to automatically order more consumables when needed. Data transmission may also enable the external device to configure the user interface module according to user preferences. The external device may be, for example, a mobile phone, a tablet, a computer, etc.

[0041] In further examples where the user interface module includes a means for physically connecting the user interface module to an external device, the connection may be configured to allow data transmission. Such a connection may include, for example, a standard data connector such as a USB Type-C connector. The data connection may enable data to be exchanged with the external device. Such data may include, for example, user-specific settings for the user interface module and / or the operably connected aerosol delivery device. Data transmission may also enable the user interface module to be configured according to user preferences using the external device. The external device may be, for example, a mobile phone, a tablet, a computer, etc.

[0042] As mentioned above, it should be understood that some of the above examples can be combined with each other. For example, a module can include one or more of the aforementioned means for user interaction, as well as power and / or data transmission functionality. Alternatively or in addition, a module can include communication functionality. Although possible module functions may be described separately, their combination within a single module is not excluded.

[0043] According to a second aspect of the present disclosure, an aerosol delivery device is provided. The device includes a housing, an aerosol generator disposed within the housing, and a connector configured to form a releasable operable connection with one or more examples of a user interface module according to the first aspect of the present invention described above. The aerosol delivery device also includes an internal power source configured to provide power to the aerosol generator, which has the advantage that the aerosol delivery device is operable even when the module is not operably connected to the device. In examples where the aerosol delivery device includes a limited internal power source, supplemental power can be provided to the aerosol delivery device, for example, to enable the aerosol generator to function in a higher power mode. Such power may be provided by an operably connected module or an external power source. Examples where the aerosol delivery device includes a limited internal power source may be advantageous because it may reduce the size, weight, and / or complexity of the aerosol delivery device.

[0044] According to a third aspect of the present disclosure, there is provided a system comprising an aerosol delivery device and a user interface module, wherein the user interface module is operably connected to the aerosol delivery device, the operably connection being either a direct connection with a connector of the aerosol delivery device or a connection with one or more other modules, at least one of which is directly connected to the connector of the aerosol delivery device, and wherein, during use, the operably connected user interface module provides additional functionality to the aerosol delivery device.

[0045] 1, a user interface module 100 for use with an aerosol delivery device is shown schematically. User interface module 100 includes a housing 102, a user interface 108 disposed in housing 102, and a connector 110, the connector configured to interface with either the aerosol delivery device or another module. In some embodiments, user interface module 100 can include a second connector 112 (shown in FIG. 1) and, optionally, additional connectors (not shown). Each of the second and additional connectors is configured to interface with either the aerosol delivery device or additional modules.

[0046] The housing 102 of the user interface module 100 may be constructed from any suitable material. Metallic materials such as steel or aluminum can be used. Stainless steel and aluminum are inexpensive, easy to manufacture, and exhibit good corrosion resistance. Housings comprising metallic materials can also improve dissipation of heat generated within the device, increasing user comfort during use and may be more aesthetically pleasing than alternative options. Conductive materials may also be used, and a housing constructed from a conductive material can further function as an antenna to facilitate or enhance wireless communication in examples where the module includes means for wireless communication, as described in more detail below. Alternatively, the housing may be made from plastic. Plastic is inexpensive, can be easily formed into the desired shape, and is non-conductive, which can help increase the safety of the device. Examples of suitable plastic materials include polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or a combination of PC and ABS. PC and ABS are strong, durable, inexpensive, and can be easily formed into the required shape. PC and ABS can also be easily colored and decorated using surface paints within the plastic material structure, allowing the housing 102 to be easily decorated. Additionally, plastic materials may be advantageous in instances where the module includes means for wireless communication, as described in more detail below, where a separate antenna may be embedded in the plastic material of the housing or printed on the exterior and / or interior surfaces of the housing 102 to facilitate or enhance wireless communication. The housing 102 may be configured to be alterable, allowing a user to replace at least a portion of the housing 102, for example to change its appearance.

[0047] The user interface module 100 includes a user interface 108. As previously described, the user interface 108 may include any suitable means by which a user can interact with the device. In use, the user interface 108 enables a user to interact with and configure the operation of an operably connected aerosol delivery device.

[0048] In one example, the user interface 108 comprises one or more buttons, switches, dials, and rotary buttons.

[0049] In another example, alternatively or additionally, the user interface 108 may be configured to provide the user with information regarding the operably connected aerosol delivery device, and such a user interface may include one or more means for providing visual feedback (light, LED, etc.), audible feedback (speaker, clicker, buzzer, etc.), or tactile feedback (vibrator, etc.).

[0050] In a further example, the user interface 108 additionally or alternatively comprises a screen. The screen may be, for example, an LCD screen. The screen may be a touchscreen configured to display information to a user and receive user input.

[0051] User interface module 100 includes connector 110, which is configured to connect to a connector of another module or aerosol delivery device. When connected to a connector of another device, user interface module connector 110 and the connector of the other device may be referred to as a "mating connector."

[0052] In some examples, first connector 110 and the additional connector are configured to form an operable connection with another module or aerosol delivery device without physical engagement of the mating connector. When housing 102 does not have any openings, housing 102 can be waterproof in that the housing material is water-resistant and the lack of openings in the housing prevents water from entering the internal components of the user interface module. Means can further be provided for securing user interface module 100 to at least one second device (the second device being another module or an aerosol delivery device) without physical engagement of the mating connector. In one example, user interface module 100 includes at least one magnet (or a portion of magnetic material) arranged such that, when the second device also includes at least one magnet, at least one magnet of the user interface module and at least one magnet of the second device secure the devices to each other by magnetic force. In this example, the one or more magnets are positioned such that user interface module 100 and the second device are aligned in such a way that magnetic forces between the magnet(s) of module 100 and the magnet(s) of the second device can operably connect the mating connectors. This type of alignment is particularly useful when the operable connection between the mating connectors is a wireless connection, and therefore there is no additional physical engagement of the parts.

[0053] In another example, the housing 102 of the user interface module 100 is configured such that, when the user interface module 100 is connected to the second device, the housing 102 secures the user interface module 100 to the second device via an interference fit. Such an arrangement may be achieved, for example, by configuring the housing 102 of the user interface module 100 such that the housing 102 is configured to at least partially surround or enclose the second device (or vice versa). Other types of physical engagement between the user interface module 100 and the second device are also possible, such as a threaded or bayonet connection, whereby a portion of the module's housing 102 includes a threaded or bayonet fitting that is inserted into a corresponding connector and twisted to form a secure engagement (or vice versa). The housing 102 may also include one or more movable engagement members, such as a latch or spring-loaded button, or means for engaging such a movable member of the second device, to increase the security of the engagement with the second device. This type of physical engagement has the advantage that the user has a tactile indication as to the security of the engagement.

[0054] In some examples, the pair of connectors are configured to physically engage to be operably connected. In these examples, the housing 102 of the user interface module 100 includes one or more openings to facilitate connection with other devices. In one example, the first connector 110 and the second connector 112 are each positioned adjacent to an opening in the housing 102 such that each of the connectors can physically engage a connector of another device when positioned within or at least adjacent to its respective opening in the housing 102.

[0055] In instances where a pair of connectors physically engage to form an operable connection, at least one of the connectors may include a "male" portion configured to be inserted into a "female" portion of a corresponding connector. Each connector may include both male and female portions, such that either connector can be connected to any other connector. However, it is preferred that connectors include only male or female portions to minimize the number of male connector portions that are not connected to female connectors during use (i.e., non-mating male connectors). By definition, male portions of connectors must extend outward. Therefore, non-mating male connectors are more susceptible to accidental damage during use of the user interface module than non-mating female connectors. Furthermore, non-mating male connectors may potentially damage external objects or cause discomfort to the user during use of the module.

[0056] In one example, first connector 110 of user interface module 100 is the only male connector of module 100. User interface module 100 may include one or more additional female connectors into which the male portion of a connector of another module or aerosol delivery device can be inserted. The user interface module may be inoperable unless first connector 110 is connected to another device (either another module or an aerosol delivery device). Thus, when first connector 110 of user interface module 100 is connected to another device, a system including one or more such modules 100 operably connected to an aerosol delivery device during use can be understood to have no module with a non-connected male connector.

[0057] In one example, user interface module 100 includes only first connector 110 and no additional connectors. This example module may be connected to only one of another module or an aerosol delivery device. User interface module 100 including only first connector 110 results in a simple design and easy manufacture of the user interface module. In such a module, it may be advantageous for first connector 110 to be a male connector.

[0058] The user interface module 100 may include a means for connecting to an external device (other than an aerosol delivery device or another module), referred to herein as an “external connector” (not shown). The external connector, configured to form a physical connection with an external device, may be a commercially available connector, such as a USB Type-C connector or a proprietary connector. Alternatively, the external connector may be a wireless external connector configured to connect wirelessly to an external device. The wireless external connector may use, for example, Bluetooth, Wi-Fi, NFC, or a cellular network connection. The external connector may enable the module 100 to receive power from the external device. Additionally or alternatively, the external connector may enable the exchange of data between the module 100 and the external device. Such data may include, for example, user-specific settings for the user interface module and / or the operably connected aerosol delivery device.

[0059] Referring to FIG. 2, aerosol delivery device 200 is shown schematically. Aerosol delivery device 200 includes a housing 202 (sometimes referred to as an "exterior cover"), an aerosol generator in the form of a heater 204 disposed within housing 202, and a connector 210 configured to interface with a module. Aerosol delivery device further includes a power source 206 disposed within housing 202 and a simple user interface 208. User interface 208 may include, for example, a single button. Aerosol delivery device 200 is configured to function independently when not connected to an additional module. Aerosol delivery device 200 may include a puff sensor (not shown) configured to detect when a user is inhaling on aerosol delivery device 200. Aerosol delivery device 200 may include an internal computer memory (not shown) configured to retain user-defined preferences after the user interface module is detached.

[0060] As previously mentioned, user interface module 100 allows a user to interact in an advanced manner with an operably connected aerosol delivery device 200 without requiring that the aerosol delivery device 200 have a complex user interface. Examples of some situations in which a user may want to interact with aerosol delivery device 200 in an enhanced manner (as opposed to a simple start / stop operation) are outlined below, along with possible settings of user interface module 100 that can facilitate such situations. It should be understood that these examples are intended only to illustrate how user interface module 100 can be configured to solve the technical problems of interacting with a simple, inexpensive aerosol delivery device 200, and that these examples should not be considered an exhaustive list of possible enhanced functions that can be provided by user interface module 100.

[0061] In one application of the user interface module 100, a user can interact with an operably connected aerosol delivery device 200 to configure the aerosol delivery device according to the user's preferences. For example, a user may wish to adjust the amount of power supplied to the aerosol generator 204 during a smoking session. The desire to modify the amount of power supplied to the aerosol generator may be based on a preferred sensory experience. Alternatively or additionally, a user may wish to adjust the amount of power supplied to the aerosol generator to facilitate the use of different types of consumables in the aerosol delivery device. It should be understood that, in general, different consumables may require the aerosol generator to use different "heating profiles" during use. The aerosol delivery device may control the amount of power supplied to the aerosol generator according to a predetermined heating profile, which is essentially a time-temperature program, so that the aerosol generator operates at a particular temperature for a predetermined time during a smoking session. The user interface module may enable a user to select between two or more predetermined heating profiles (e.g., a low-power heating profile and a high-power heating profile). More complex user interface modules may allow the user greater control over the heating profile.

[0062] To enable a user to configure the aerosol delivery device in this manner, an operably connected user interface module may include a user interface including, for example, a single button and means, such as one or more LEDs, for indicating to the user the currently operating heating profile of the aerosol generator. The single LED may be configured to indicate the selected heating profile, for example, by indicating it with a different brightness, color, and / or by flashing in a certain pattern. The user can then press a button to change to a different pre-set heating profile. Alternatively, two or more buttons may be provided to make selecting a particular heating profile easier. Alternatively, the single LED may be replaced with several LEDs, with the number of illuminated LEDs indicating the selected power level. Alternatively or additionally, the selected heating profile may be indicated to the user audibly (using a speaker, clicker, buzzer, etc.) or via tactile feedback such as a vibrator. Alternatively, the heating profile may be selected by the user using a user interface element, such as a dial or rotary button, that simultaneously indicates the currently selected heating profile, with a predetermined / pre-set value displayed on the dial / rotary button. More detailed information regarding the selected heating profile and available options may be provided by including an LCD display configured to display digital letters / numbers. Alternatively, a more advanced display may be provided to provide more information to the user. Such a display may be a touchscreen display, which greatly enhances ease of user interaction. A more complex user interface, such as a more advanced display capable of displaying menu options and other features, may allow the user to have more control over the heating profile applied to the aerosol generator (while the aerosol generator is in use).For example, a complex display (which may be a touchscreen) may allow the user to modify the details of an existing heating profile or to create an entirely new heating profile according to the user's preferences.

[0063] As previously mentioned, the user interface module may be configured to allow a user to adjust the amount of power supplied to the aerosol generator of the aerosol delivery device during use. This may facilitate many options for a user to use the user interface module to improve their experience when using the aerosol delivery device. Examples outlining some of the options that may be set using the user interface module are described below. It should be understood that these examples are only a few of the possible options envisioned and should not be considered an exhaustive list of possibilities. Furthermore, any of the examples outlined below may be used alone or combined in some way to improve the user experience using a single user interface module.

[0064] A user can configure the aerosol delivery device (using the user interface module) to automatically switch to a higher power mode (i.e., supply a greater amount of power to the aerosol generator) when external power is supplied to the aerosol delivery device. Such external power may be supplied from a power source included in an operably connected module (including the user interface module itself) or from an external device such as a plug inserted into a wall socket. The aerosol delivery device may be configured to switch to a lower power mode (i.e., supply a lesser amount of power to the aerosol generator) when external power is no longer supplied. A user can configure the user interface module to determine the amount of externally supplied power and switch to a higher power mode only if it is determined that the amount of externally supplied power exceeds a predetermined threshold. Alternatively, the user interface module may be configured by the user to determine the amount of externally supplied power and switch to the highest power mode for which the power supply is determined to be sufficient. The possible power modes may be preset or may be configured by the user using the user interface module.

[0065] In examples where the user interface module is configured to determine the amount of power provided to the aerosol delivery device and the aerosol delivery device includes a rechargeable internal power source, a user can use the user interface module to ensure that the internal power source is given priority for charging before power is otherwise provided to the aerosol delivery device or other components. Furthermore, a user can configure the user interface module to automatically switch to a higher power mode only if the externally provided power is sufficient to charge the aerosol delivery device's internal power source and operate the aerosol delivery device in the higher power mode. The user interface module may be configured to determine the amount of externally provided power and switch to the highest power mode for which the power supply is determined to be sufficient, while prioritizing charging the aerosol delivery device's internal power source. The possible power modes may be preset or set by a user using the user interface module. The user interface module may be configured by a user to stop prioritizing charging the aerosol delivery device's internal power source when the aerosol delivery device's internal power source is charged or when the internal power source has charged to a predetermined amount (which may be user-selectable).

[0066] A user can use the user interface module to configure the aerosol delivery device to automatically activate the aerosol generator when the puff detector detects that the user is inhaling on the device. A user can configure the aerosol generator to operate for a predetermined period of time after a puff is taken by the user, or to switch off immediately after a puff is completed. A user can configure the aerosol generator via the user interface module to operate in a low-power mode rather than shutting off between puffs. A user can configure the aerosol generator to shut off after a predetermined period of time without a puff. A user can configure the user interface module to require input from another user interface component (such as a button on the user interface module or the aerosol delivery device) before considering input from the puff sensor.

[0067] In another example where a user may want to configure the aerosol delivery device, the user can use the user interface module to configure the aerosol delivery device to require an unlock code to activate the device. Such an unlock code allows the user to prevent unauthorized use of the device. The unlock code can include physical, audible, and / or tactile interaction with the user interface module or the aerosol delivery device. If the user configures the aerosol delivery device to be “locked” (i.e., requiring an unlock code to be entered into the user interface module), the aerosol delivery device will not function until a user-defined unlock code is entered into the operably connected user interface module or aerosol delivery device. During use, the user can configure the aerosol delivery device to be locked or unlocked after the user interface module is detached. For example, if the user wants to use the aerosol delivery device immediately after the user interface module is detached, the user can configure the aerosol delivery device to remain unlocked after the module is detached. Alternatively, if the user does not want to use the aerosol delivery device immediately after the user interface module is detached, the user can configure the aerosol delivery device to be locked after the user interface module is detached. If the user sets the aerosol delivery device to be locked, the user interface module is operably connected to prevent further use of the aerosol delivery device after the module is disconnected until the previously set unlock code is entered.

[0068] In addition to allowing a user to configure the characteristics of the aerosol delivery device, the user interface module may allow a user to review information stored in the aerosol delivery device's internal computer memory, if provided. The user interface module may also allow a user to review information stored in the user interface module's internal computer memory, whether this data was previously copied from the aerosol delivery device's internal computer memory, or stored locally on the user interface module, or obtained from an external device or cloud data source.

[0069] For example, a user may wish to view information regarding the use of the aerosol delivery device. Simple information, such as the remaining power of an internal power source contained within an operably connected aerosol delivery device, may be communicated to the user by a user interface component, such as one or more LEDs. Additionally or alternatively, such information may be provided by simple audible feedback (such as a clicker or buzzer) or tactile feedback, such as a vibrator. The user may also be communicated the remaining power of the internal power source of the aerosol delivery device in terms of an estimated number of smoking sessions remaining or an estimated number of puffs remaining in a particular smoking session, as determined by the user interface module from previous user data or a lookup table.

[0070] A more complex user interface, such as a display, may be necessary to provide more detailed or advanced information to the user. More complex information may be, for example, a detailed analysis of previous smoking sessions. Such analysis may enable the user to modify their use of the aerosol delivery device during a smoking session to improve their experience, for example, by varying the duration and / or amount of puffs. Detailed information about previous use of the aerosol delivery device may also provide the user with healthcare and wellness information.

[0071] In examples of user interface modules that include means for communication with external devices (e.g., physical connections or wireless means such as Bluetooth, Wi-Fi, and cellular data), the user interface module may be able to provide information to a user via the external device. This may allow the user to review the information on a computer, for example. A user may also configure such a user interface module to use the connection with the external device to order additional consumables when needed. The need for additional consumables may be determined manually by the user or may be automatically inferred by the user interface module based on previous use of the aerosol delivery device or standard predetermined data.

[0072] 3, a system including an aerosol delivery device 200 and a user interface module 100 is shown schematically. A connector 210 of the aerosol delivery device 200 is directly connected to a first connector 110 of the module. In such a system, the user interface module 100 can include a second connector 112 to which an additional module can be connected. The aerosol delivery device 200 can include the second connector and further connectors (not shown) configured to connect to the additional modules.

[0073] FIG. 4 shows a further example of an aerosol delivery device 400 including a housing 402, an opening 403 in the housing configured to allow an article containing aerosol-generating material 600 to be inserted into the aerosol delivery device, a heater 404, a user interface 408 that is a simple on / off switch, and a connector 410. In this example, the user interface is a single button that can be configured to activate and / or deactivate the heater. As shown in FIG. 4 , the article containing aerosol-generating material 600 is inserted into opening 403 and extends into heater 404 within housing 402. In this example, aerosol delivery device 400 does not include an internal power source and must be connected during use to either a module configured to provide power to the aerosol delivery device or an external power source.

[0074] 5 illustrates another example of a system including aerosol delivery device 400 and a user interface module 500. User interface module 500 illustrated in FIG. 5 includes a housing 502 and a user interface 508 disposed in housing 502. In this illustrated example, user interface 508 is a touchscreen. Because user interface 508 is a touchscreen, no other user interface components are provided on module 500, although additional user interface components may be present in some examples.

[0075] In this example, user interface module 500 is configured such that when a first connector of aerosol delivery device 400 is operably connected to a first connector (not shown) of the module, module 500 partially surrounds aerosol delivery device 400. Such a configuration improves the strength and durability of the connection between aerosol delivery device 400 and module 500, providing an overall more robust system. Such a configuration also reduces the likelihood that the operable connection will be accidentally disconnected during use, for example. Such a configuration may also be more ergonomic than other configurations during use, providing increased user comfort.

[0076] 5 are configured to slide into place so that the aerosol delivery device 400 is operably connected to the module 500. In such a configuration, the module 500 and the aerosol delivery device 400 may include means to assist a user in properly aligning the two connectors. For example, to properly align the first connector 410 of the aerosol delivery device with the first connector 510 of the module 500, the housing 502 of the module 500 may include a guide groove into which a protrusion disposed on the housing 402 of the module 400 can slide.

[0077] Figure 6 is an alternative view of the example shown in Figure 5. In the example shown in Figure 6, user interface module 500 is shown with two connectors 512, 514 in addition to a first connector (not shown) connected to aerosol delivery device 400. As previously mentioned, the user interface module may include second or further connectors configured to connect to additional modules. Such additional modules may provide additional functionality to an operably connected aerosol delivery device 400 during use. For example, additional power may be provided to the system by connecting an additional module with an internal power source to one of the additional connectors (512 or 514).
