Description

The present invention relates to an aerosol generating system, a device for use with such a system, and a method for generating an aerosol. In particular, the present invention relates to hand-held aerosol-generating systems and devices that vaporize an aerosol-forming substrate by heating to generate an aerosol to be drawn or inhaled by a user, and that include an interface element.

One type of aerosol generating system generates an aerosol to be drawn or inhaled by the user using electrical heating (see for example KR 101214363 B1, A24F 47/00, 12/24/2012). Such electrically heated aerosol generating systems come in various forms. Some types of similar systems are electronic cigarettes that vaporize a liquid or gel-like substrate to form an aerosol, or they release an aerosol from a solid substrate by heating it to a certain temperature below the combustion temperature of the solid substrate.

Hand-held electrical aerosol-generating devices and systems are known that consist of a device-like portion containing a battery and an electronic control circuit; parts for storing or receiving an aerosol-forming substrate; and an electrical heater for heating the aerosol-forming substrate to generate an aerosol. Also included is a mouthpiece portion on which a user can puff to draw the aerosol into his or her mouth.

Some devices and systems use a liquid or gel-like aerosol-forming substrate stored in a storage portion. Such devices may use a wick to transfer liquid or gel aerosol-forming substrate from a storage portion to a heater where the substrate is converted into an aerosol. Such devices may use a displacement mechanism, such as a pump and piston, to force the liquid or gel aerosol-forming substrate from the storage portion to the heater. Aerosol-generating devices and other types of systems use a solid aerosol-forming substrate that contains tobacco material. Such devices may include a recess for receiving a cigarette-shaped rod containing a solid aerosol-forming substrate, such as folded sheets, that contain tobacco material. A blade-shaped heater located in said recess is inserted into the center of the rod while placing the rod in said recess. The heater is configured to heat the aerosol-forming substrate to generate an aerosol without substantially burning the aerosol-forming substrate.

Electrically heated aerosol-generating systems can provide a user experience that is significantly different from that created by conventional combustion-based cigarettes. For example, the user interacts with the device rather than lighting a cigarette. The electrically heated aerosol generating system can be activated using a mechanical on/off button. However, a mechanical button may provide only limited interaction with the system for the user, and may allow use of the system by unapproved users. In addition, a mechanical button is a factor in the potential for mechanical failure of the system's control components (such as the button or its associated circuitry) over time. For example, cyclic loading may cause wear, cyclic fatigue of control components, or the like. Some devices provide more than one button to enhance interaction between the user and the system, for example, to allow the user to better control system functions, initiate various processes, or the like. Some devices may contain a touch screen or biometric sensor to accept input from the user or to authenticate the user. However, these various interactions can be confusing for the user and result in an increased number of components that are prone to failure and incur associated manufacturing costs.

The objective of the present invention is to provide the user with easily understandable feedback that conveys meaningful information. Another object of the present invention is to prevent unapproved users from using the system. Another object of the present invention is to provide an attractive, smooth and continuous outer surface of the system. Another object of the present invention is to reduce the number of mechanical components used in a system.

According to an aspect of the present invention, an aerosol generating system is provided. The system may include a housing. The housing may include a top surface. The housing may include a bottom surface. The housing may contain a plurality of areas. The system may contain an interface element. The interface element may contain a plurality of elements for detecting contact. Each contact detection element may be configured to generate an input signal in response to the contact detection element detecting contact with a specified top surface in or near one of the plurality of specified regions. The system may include circuitry configured to receive input signals from said plurality of elements to detect contact. The circuitry may be configured to activate a first function of the aerosol generating system in response to a first plurality of input signals satisfying the first criterion. Said first criterion may include said circuit receiving a predetermined number of input signals simultaneously.

According to an embodiment, an aerosol generating system is provided, comprising a housing having an upper surface, a lower surface, and a plurality of regions. The system includes an interface element comprising a plurality of contact detection elements, each contact detection element configured to generate an input signal in response to the contact detection element detecting contact with a top surface in or near one of the plurality of specified regions. The system also includes circuitry configured to receive input signals from said plurality of contact detection elements and to activate a first function of the aerosol generating system in response to a first plurality of input signals satisfying a first criterion, wherein said first criterion includes said circuitry simultaneously receiving a predetermined number of input signals.

In use, determining whether the first criterion is satisfied may constitute or be part of an authentication procedure. In use, the user may hold the housing or otherwise place their hand on it. Each of the number of contact detection elements may then generate an input signal in response to the contact detection element detecting contact with a top surface in or near one of the plurality of regions. The number of input signals generated can serve as an indicator of the size of the user's hand. The number of inputs generated may indicate whether a given user is a specific user or an approved type of user. For example, generating a number of input signals that is less than a predetermined number (and having said circuit receive a number of signals that is less than said predetermined number) may indicate that the user is a child with small hands. Thus, the first criterion may not be satisfied and the first function may not be activated. Conversely, generating exactly the same or more output signals (and receiving exactly the same or more input signals by said circuit) may indicate that the user has large hands and is therefore an adult. Thus, the first criterion can be satisfied and the first function can be activated.

This provides the advantage that the first criterion can be used as a new and reliable authentication procedure. This has the advantage that the system may not need to have any moving parts to satisfy the first criterion. This has the advantage that the use of any biometric sensors, such as fingerprint sensors, may not be required to satisfy said first criterion. This makes it possible to reduce the cost of manufacturing the system.

For the avoidance of doubt, unless otherwise indicated, simultaneous reception of a given number of signals includes simultaneous reception of exactly a given number of signals, as well as simultaneous reception of a number of signals that is greater than a given number.

Said predetermined number may correspond to the number of input signals that are expected to be generated upon contact of the particular user or type approved user, such as the hand of the particular user or type approved user, with the top surface.

This has the advantage that the system can only enable the first function to be activated for a specific user or an approved type of user.

Said predetermined number may correspond to a number of input signals expected to be generated upon contact of a hand of at least a predetermined size with said top surface. A hand having at least a given size may indicate that the user is a specific user or an approved type of user. A hand having at least a given size may indicate that the user is an adult.

This has the advantage that the system only allows the first function to be activated by a user having a hand of at least a given size. This may mean that the first function is not activated for a user with a hand smaller than the specified size. This makes it possible to prevent children with small hands from activating the first function.

Said predetermined number may correspond to a number of input signals generated upon contact with a predetermined portion of the surface or portion of the surface of the housing. For example, said target amount may correspond to the number of input signals generated upon contact with more than 10, 20, 30, 40, 50, or 60% of a surface or portion of a surface of the housing, such as a forward-facing surface of the housing or a rear-facing surface of the housing. This has the advantage of being able to provide a reliable method of determining the user's hand size. Thus, this provides the possibility of creating a reliable method for preventing children with small hands from activating the first function.

Said predetermined number may correspond to a number of input signals generated upon contact with a predetermined portion of the upper surface of the housing or a portion of the upper surface of the housing. For example, said target amount may correspond to the number of input signals generated upon contact with more than 10, 20, 30, 40, 50 or 60% of the top surface of the housing or more than 10, 20, 30, 40, 50 or 60% of the top surface area a housing, such as a forward-facing upper housing surface or a rearward-facing upper housing surface. This has the advantage of being able to provide a reliable method of determining the user's hand size. Thus, this provides the possibility of creating a reliable method for preventing children with small hands from activating the first function.

At least one of the plurality of contact detection elements may comprise a temperature sensing element.

At least one of the plurality of contact detection elements may comprise a capacitive sensor.

At least one of the plurality of contact detection elements may comprise a pressure sensor.

Determining whether the first criterion is satisfied may be part of a multi-step authentication procedure.

An advantage is provided that the multi-step authentication procedure can improve the security of the system.

The first function may be to initiate an authentication procedure. If the satisfaction of the first criterion is itself considered to be an authentication procedure, then the initiation of a second authentication procedure can be considered as the specified first function. This provides the advantage of being able to increase system security.

The circuit may be configured to activate the first function if the alternative authentication procedure based on satisfaction of the first criterion is successfully completed. The system may be configured, for example, by a user, such that the circuitry is configured to activate the first function if an alternative authentication procedure based on satisfaction of the first criterion is successfully completed. The system may be configured, for example, by a user between a first state in which satisfaction of a first criterion is an essential condition for activating the first function, and a second state in which said circuitry is configured to activate the first function if an alternative authentication procedure based on meeting the first criterion has been successfully completed. An alternative authentication procedure may include one or more of the following:

using a fingerprint sensor to receive a fingerprint and compare that fingerprint with a stored fingerprint;

the use of voice recognition technology, consisting, for example, in the fact that the system asks the user a question, receives a voice sample from the user in response to the specified question, and compares the voice sample with previously stored voice information (for example, determines that the voice frequency is below a certain frequency, or belongs to a specific user, or fulfills another definition, such as those commonly used in telephone banking technology);

Receiving a password or code from the user (for example, a password entered as characters, a password entered using a sequence of touches, or an audio password).

This provides the advantage that the approved user may be allowed to activate the first function if he is unable to meet the first criterion, for example if the approved user has too small hands to meet the first criterion, or if the interface element is faulty.

The system, such as said system circuitry, may be configured to determine the length of time during which at least one or each contact detection element has detected contact with a top surface in or near one of the plurality of said regions.

Said first criterion may include receiving a predetermined number of input signals from said plurality of contact detection elements or a second predetermined number of input signals from said plurality of contact detection elements that indicate contact with the top surface for a time greater than a predetermined period of time.

Said specified time period may be greater than 0.1, 0.2, 0.5, 1, 2, 3, or 5 seconds. This specified time period may be less than 10 or 5 seconds.

This has the advantage of being able to reduce the risk of unintentionally activating the first function.

The first criterion may include receiving a predetermined number of input signals from said plurality of contact detection elements or a second predetermined number of input signals from said plurality of contact detection elements that indicate contact with the top surface for a time that is less than the second predetermined period of time.

The second predetermined period of time may be less than 10 or 5 seconds. The second specified time period may be greater than 1 second.

For example, the first criterion may include receiving a second predetermined number of input signals from the plurality of contact detection elements indicative of contact with the top surface for 0.5 to 5 seconds or for 1 to 5 seconds.

The first criterion may include simultaneously receiving a first predetermined number of input signals in response to detection of contact with a top surface in or adjacent to a first region of the plurality of regions, and a second predetermined number of input signals in response to detection of contact with a top surface in a second region of the plurality of regions. areas or near it. The first region may be spaced from the second region by at least 5, 10, 20 or 50 millimeters.

The first region and the second region may not be located in the same plane. For example, the first region may be located on or near a forward-facing surface of the casing (e.g., a forward-facing top surface), and the second region may be located on a rear-facing or side-facing surface (e.g., a rear-facing or side-facing top surface) of the casing or near her.

The first criterion may include simultaneously receiving at least one input signal in response to the contact detection element detecting contact with the first portion of the upper surface, and at least one input signal in response to the contact detecting element detecting the contact. with the second section of the upper surface. The first top surface portion and the second top surface portion may not be coplanar. In other words, the first upper surface portion and the second upper surface portion may lie in different planes. For example, the first portion may be located on a forward-facing portion of the top surface, and the second portion may be located on a sideways or rearward-facing portion of the top surface.

Said first criterion may include simultaneously receiving an nth predetermined number of input signals in response to detecting contact with a top surface in or near the nth region of n regions of said plurality of regions, where n is an integer greater than or equal to 2.

The integer n may be equal to or may be equal to at least 3, 5, 10, 20, 50, or 100.

For example, said first criterion may include simultaneously receiving at least one input signal in response to detection of contact with a top surface in each of said n (e.g., 3, 5, 10, 20, 50, or 100) regions in or near said plurality of regions .

Each of the n regions may be at least 0.1, 0.2, 0.5, 1, 2, 5 or 10 millimeters away from every other region of the n regions.

For example, each of the 3, 5, 10, 20, 50, or 100 regions may be at least 0.1, 0.2, 0.5, 1, 2, 5, or 10 millimeters from every other region of the 3. 5, 10, 20, 50 or 100 areas.

Said first criterion may include simultaneously receiving at least one input signal in response to detection of contact with a top surface in a number of areas greater than a specified number or fraction of said n (e.g., 3, 5, 10, 20, 50, or 100) areas of said multiple areas, or near them, for example, more than 20%, 40%, 60%, 80% or 90% of the specified number of areas. As will be apparent to those skilled in the art, if such a fraction is not a whole number, then the fraction may be rounded to the nearest whole number.

In one example, said first criterion may include simultaneously receiving at least one input signal in response to detection of contact with a top surface in or near each of 3 or 5 regions of said plurality of regions, and each of said 3 or 5 regions may be spaced by at least 2 or 5 millimeters from every other area of the specified 3 or 5 areas.

In yet another example, said first criterion may include simultaneously receiving at least one input signal in response to detection of contact with a top surface in each of 50 or 100 regions of or near said plurality of regions, and each of said 50 or 100 regions may be spaced at least 0.1, 0.2 or 0.5 millimeters from every other area of the specified 50 or 100 areas.

In yet another example, said first criterion may include simultaneously receiving at least one input signal in response to detection of contact with a top surface in at least 60% or 80% of 20, 50, or 100 areas of or near said plurality of areas, and each of said 20, 50 or 100 regions may be at least 0.1, 0.2 or 0.5 millimeters apart from each other region of said 20, 50 or 100 regions.

At least 2 of the specified n regions may be located in different planes. At least 2 of said n regions may be located on or near different surfaces of the housing, such as surfaces that are not coplanar. For example, at least one of the n regions may be located on or near a forward-facing surface (such as a forward-facing top surface) of the housing, and at least one of the n regions may be located on a rear-facing or side-facing surface (such as the rear-facing or side-facing top surface) of the housing, or near it.

These features provide the advantage of being able to provide some indication of where contact is being detected on the housing. This allows the system to differentiate between, for example, two hands of a child contacting the top surface and one hand of an adult contacting the top surface, even if the total contact area is the same in the two cases. Thus, this provides the advantage of being able to increase the security of the system.

The cover may not have buttons. The housing may not contain moving parts. This has the advantage of being able to reduce the risk of mechanical damage to the system. According to an aspect of the present invention, a method of using an aerosol generating system is provided. The method may include generating, by an interface element including a plurality of contact detection elements, a plurality of input signals in response to detecting contact with an upper surface of the casing in or near respective regions of the casing. The method may include said circuit receiving said plurality of input signals. The method may include said circuitry activating a first function of the aerosol generating system in response to a plurality of input signals satisfying the first criterion. Said first criterion may include said circuit receiving a predetermined number of input signals simultaneously.

According to an embodiment, a method of using an aerosol generating system is provided. The method includes generating, by an interface element comprising a plurality of elements for contact detection, a plurality of input signals in response to detecting contact with an upper surface of the casing in or near respective regions of the casing; receiving by said circuitry said plurality of input signals and activating by said circuitry a first function of the aerosol generating system in response to said plurality of input signals satisfying the first criterion. The first criterion involves the specified circuit receiving a specified number of input signals simultaneously.

This provides the advantage that the first criterion can be used as a new and reliable authentication procedure. The advantage is that the first criterion may not require any moving parts in the system. The advantage is that the first criterion may not require the use of any biometric sensors, such as fingerprint sensors. This makes it possible to reduce the cost of manufacturing the system.

The vapor may condense to form an aerosol, such as a suspension of fine solid particles or liquid droplets in a gas such as air. The aerosol-forming substrate may conveniently be part of an aerosol-generating system. In some configurations, the aerosol-forming substrate contains a gel or liquid, while in other configurations, the aerosol-forming substrate contains a solid. The aerosol-forming substrate may contain both liquid and solid components.

As used herein, the term “aerosol generating device” refers to a component of an aerosol generating system that interacts with the aerosol-forming substrate of an aerosol generating article to generate an aerosol.

As used herein, the term “peripheral device” refers to a device that is part of an aerosol generating system and interacts directly or indirectly with the aerosol generating device, but is not itself an aerosol generating device. Examples of peripheral devices include, but are not limited to, a charger for an aerosol generating device, a charging case for an aerosol generating device, a holder for one or more aerosol generating products, or a vending machine configured to sell aerosol generating devices or aerosol generating products.

As used herein, the term “connected” refers to an arrangement of elements such that they can directly or indirectly contact each other. Elements that are "directly" connected to each other touch each other. Elements that are "indirectly" connected to each other do not directly touch each other and are attached to each other by one or more intermediate elements. Depending on the specific arrangement, elements that are part of the same device or system may "directly" contact each other or "indirectly" contact each other.

As used herein, the terms "top" and "bottom" refer to the relative positions of the parts of an element when the element is in a vertical position. When describing the surfaces of the casing according to the present invention, these terms are used regardless of the orientation of the surface of the casing.

As used herein, the terms “top surface” and “bottom surface” respectively refer to the opposing major surfaces of an element. The top surface and bottom surface of the element can be spaced from each other by a distance equal to the thickness of the element.

As used herein, the term “outer surface” refers to the surface of an element that faces outward from the aerosol generating system or device.

As used herein, the expression "substantially flat" refers to an element that is formed in a single plane and, for example, is not wrapped around or otherwise adapted to an object of a curved or non-planar shape. One region of an element may be substantially flat, while another region of the same element may be curved or otherwise have a non-planar shape.

A visible light signal is in the optical range of the electromagnetic spectrum and includes one or more wavelengths in the range from about 380 to about 740 nanometers to which the human eye typically responds.

As used herein, the term “at least partially transparent” refers to an element capable of transmitting a visible light signal through it.

As used herein, the term "contact detection element" refers to an element that detects contact with a user. Typically, such contact of the contact detection element occurs with a part of the user's body, such as one or more of the user's finger, palm, or lips. Non-limiting examples of contact detection elements include capacitive sensors, pressure sensors, and temperature sensing elements. Contact may involve a movement, a press (which can be long or short), or a prolonged touch.

As used herein, the term “temperature sensing element” refers to a contact detection element that detects contact with a user based on heat transferred from the user to the thermal sensing element during such contact.

As used herein, the term "thermal coupling" refers to elements connected to each other in such a way that the temperature of one of such elements affects the temperature of another of such elements. For example, thermal coupling between a user and a temperature sensing element allows heat to be transferred from the user to the temperature sensing element, and thereby influences the temperature of the temperature sensing element. Such thermal communication may occur through one or more intermediate elements. For example, the user may contact, and thus be in thermal communication, with the top surface of the housing, which is in thermal communication with the temperature sensing element, and therefore, the user may be in thermal communication with the temperature sensing element through the housing.

As used herein, the term “detectable temperature change” refers to a change in temperature that can be detected by a temperature sensing element.

For example, a detectable temperature increase may range from about 0.02 degrees Celsius to about 5 degrees Celsius, or from about 0.05 degrees Celsius to about 2 degrees Celsius, or from about 0.1 degrees Celsius to about 1 degree Celsius. Alternatively, the detectable temperature increase may range from about 0.02 to 10 degrees Celsius, or it may range from about 0.05 degrees Celsius to about 10 degrees Celsius, or it may range from about 0.1 degrees Celsius to about 10 degrees Celsius, or it can range from about 0.1 degrees Celsius to about 10 degrees Celsius, or it can range from about 0.2 degrees Celsius to about 10 degrees Celsius, or it can range from about 0.5 degrees Celsius to about 10 degrees Celsius, or it can range from about 1 degree Celsius to about 10 degrees Celsius, or it can range from in the range of about 0.05 degrees Celsius to about 5 degrees Celsius, or it can be in the range of about 0.1 degrees Celsius to about 5 degrees Celsius, or it can be in the range of about 0.5 degrees Celsius to about 5 degrees Celsius, or it may range from about 0.5 degrees Celsius to about 2 degrees Celsius, or it can range from about 0.02 degrees Celsius to about 35 degrees Celsius , or it may range from about 0.05 degrees Celsius to about 35 degrees Celsius, or it may range from about 0.1 degrees Celsius to about 35 degrees Celsius, or it may range from about 0.1 degrees Celsius to about 35 degrees Celsius, or it may range from about 0.2 degrees Celsius to about 35 degrees Celsius, or it can range from about 0.5 degrees Celsius to about 35 degrees Celsius, or it may range from about 1 degree Celsius to about 35 degrees Celsius.

The contact of the temperature sensing element with the user in (ii) can be determined by the start of contact and the end of contact. The temperature of the temperature-sensitive element in (ii) can be measured between the moment the contact begins and the moment the contact ends, i.e. during actual contact, or it can be measured during a short period of time after the end of contact. For example, the temperature of the temperature sensing element in (ii) may be measured from about 0 seconds to about 5 seconds, or from about 0 seconds to about 3 seconds, or from about 0 seconds to about 1 second from the end of contact.

For example, in other configurations, the interface elements of the present invention may be used with or incorporated into aerosol generating systems or aerosol generating devices that are configured for use with a solid aerosol-forming substrate. One type of aerosol generating element that can be used with a solid aerosol-forming substrate includes a heater configured to be inserted into the solid aerosol-forming substrate, such as a tobacco plug.

In some configurations, the heater is substantially blade-shaped for insertion into the aerosol-forming substrate and optionally has a length of 10 mm to 60 mm, a width of 2 mm to 10 mm, and a thickness of 0.2 mm to 1 mm.

For example, the first material may be Ni-Cr (nickel-chromium), platinum, tungsten or alloy wire, and the second material may be gold, silver or copper. The dimensions of the first and second portions of the heating element may also be different to provide lower electrical resistance per unit length in the second portion.

The heater substrate is made of an electrically insulating material, and it may be made of a ceramic material such as zirconia or alumina. The heater substrate provides mechanically stable support for the heating element over a wide temperature range, and is capable of providing a rigid structure suitable for insertion into an aerosol-forming substrate.

Alternatively, the solid aerosol-forming substrate may comprise a non-tobacco material. The solid aerosol-forming substrate may further comprise an aerosol-forming agent that promotes the formation of a dense and stable aerosol. Examples of suitable aerosol-forming substances are glycerin and propylene glycol.

The solid aerosol-forming substrate may contain, for example, one or more of the following: powder, granules, pellets, pieces, thin tubes, strips or sheets containing one or more of the following: grass leaves, tobacco leaves, tobacco stem fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, cast tobacco sheet and expanded tobacco.

If desired, the solid aerosol-forming substrate may contain additional tobacco or non-tobacco volatile flavor compounds to be released upon heating of the substrate. The solid aerosol-forming substrate may also contain capsules that contain, for example, additional tobacco or non-tobacco volatile flavor compounds, and such capsules may melt when the solid aerosol-forming substrate is heated.

As used herein, the term “homogenized tobacco” refers to the material obtained by agglomerating bulk tobacco. Homogenized tobacco may be in leaf form. The content of the aerosol-forming agent in the homogenized tobacco material may be greater than 5% on a dry weight basis. Alternatively, the aerosol-forming agent content of the homogenized tobacco material may range from 5% to 30% by weight on a dry weight basis.

If desired, the solid aerosol-forming substrate may be provided on or embedded in a thermally stable carrier. The carrier may be in the form of powder, granules, pellets, pieces, thin tubes, strips or sheets. Alternatively, the carrier may be a tubular carrier having a thin layer of solid substrate applied to its inner surface and/or its outer surface. Such a tubular carrier may be made, for example, of paper or paper-like material, non-woven carbon fiber mat, lightweight open cell metal mesh, or perforated metal foil, or any other heat-stable polymer matrix.

In some configurations, the aerosol-forming substrate comprises an assembled corrugated sheet of homogenized tobacco material. As used herein, the term “corrugated sheet” means a sheet having a plurality of substantially parallel folds or corrugations. Preferably, when the aerosol generating article is assembled, said substantially parallel folds or corrugations extend along or parallel to the longitudinal axis of the aerosol generating article.

The solid aerosol-forming substrate may be applied to the surface of the carrier in the form of, for example, a sheet, foam, gel or slurry. The solid aerosol-forming substrate may be applied to the entire surface of the carrier or, alternatively, it may be applied in a pattern to provide non-uniform delivery of flavor during use.

Said one or more contact detection elements are configured to detect contact with the housing of the aerosol generating system. If desired, the interface element may further comprise one or more light emitting elements that transmit light through the aerosol generating system housing. The interface element may be coupled to the aerosol generating system such that the housing has a smooth and continuous outer (top) surface. Such a smooth or continuous outer surface may provide a more ergonomic device, or it may be attractive to the user. In some embodiments, the interface element may be configured to authenticate users and limit or prevent use of the aerosol generating system by unauthorized users. The light emitting element(s), if present, may emit light of one or more wavelengths that are different from each other and which can be perceived by the user as different colors. In those configurations that include light emitting element(s), such wavelengths may optionally be used to convey information to the user, or they may be used as an element of the authentication process. If necessary, the casing does not contain any mechanical buttons. Other types of standard input elements, such as biometric sensors or touch screens, can be eliminated from the aerosol generating system. For example, an interface element may optionally be provided as the sole means for providing information to the aerosol generating system and for communicating information from the aerosol generating system to the use of the system. This makes it possible to reduce or eliminate potential fault factors. EFFECT: possibility of reducing production costs of an aerosol generating system. It is possible to simplify the user's experience. This provides the opportunity to improve the user experience, reduce system costs, and improve control.

The interface element of the present invention can be used in any suitable aerosol generating system or component thereof. For example, in FIG. 1 is a schematic illustration of an aerosol generating system 100 including an interface element 30 in accordance with the present invention. System 100 includes an aerosol generating article 20 containing an aerosol-forming substrate, and an aerosol generating device 10. In the embodiment shown in FIG. 1, the aerosol generating article is provided in the form of a cartridge 20 containing one or both of a liquid and a gel aerosol-forming substrate. In other embodiments, the aerosol-forming substrate may be a solid aerosol-forming substrate, such as those described with reference to FIG. 2.

In the embodiment shown in FIG. 1, the connecting end of the cartridge 20 is releasably connected to a corresponding connecting end of the aerosol generating device 10. The aerosol generating device 10 includes a housing 11 that has an upper surface 16, a lower surface 17, and at least one area 18. Optionally, an upper surface 16 of the housing 11 is substantially flat within the area 18. If desired, the housing 11 may be button-free, that is, it may not contain any buttons. If desired, the top surface 16 of the housing 11 can be substantially smooth and continuous. It should be understood that the housing 11 may, but does not necessarily have to, be considered part of the interface element of the present invention. Housed within the housing 11 are a battery 12, which in one example is a rechargeable lithium-ion battery, a control circuit 13, and an interface element 30 connected to the control circuit 13 by an electrical connection. The aerosol generating system 100 is portable and can be of a size comparable to a conventional cigar or cigarette. For example, the system 100 is preferably sized and shaped to be held in the hands, and preferably sized and shaped to be held in one hand, such as between the fingers of a user.

The cartridge 20 includes a housing 21 containing a heating assembly 25 and a reservoir 24. The reservoir 24 stores a liquid or gel-like aerosol-forming substrate. The upper part of the reservoir 24 is connected to the lower part of the reservoir 24, as shown in the figure. Heating unit 25 receives substrate from reservoir 24 and heats the substrate to generate steam; for example, it includes a resistive heating element connected to the controller 13 through electrical connections 26, 14 to receive power from a battery 12. One side of the heating assembly 25 is in fluid communication with the reservoir 24 (for example, through fluid channels 27) to receive a generator. aerosolizing the substrate from reservoir 24, for example by capillary action. The heating unit 25 is configured to heat the aerosol-forming substrate to generate steam.

In the configuration shown in the figures, air flow path 23 extends through cartridge 20 from air inlet 15 (which may optionally be located between aerosol generating device 10 and cartridge 20) past heating assembly 25 and through path 23 through reservoir 24 to mouthpiece opening 22 There are 21 cartridges in the casing at the end. The system 100 is designed such that the user can draw through an opening 22 on the mouth end of the cartridge 20 to draw the aerosol into his mouth. During operation, when the user draws from the mouth end opening 22, air from the air inlet 15 is drawn into and past the heating unit 25 into the air flow path 23, as shown by the dotted arrows in FIG. 1, to hole 22 at the mouthpiece end. The control circuit 13 controls the supply of electrical power from the battery 12 to the cartridge 20 through electrical connections 14 (in the aerosol generating device 10) connected to electrical connections 26 (in the cartridge 20) when the system is activated. This, in turn, controls the amount and properties of steam produced by the heating assembly 25. The control circuit 13 may include an air flow sensor (not specifically shown), and the control circuit 13 may provide power to the heating assembly 25 when a user takes a puff on the cartridge 20. which is detected by the air flow sensor. This type of control arrangement is common in aerosol generating systems such as inhalers and electronic cigarettes. When the user draws through the opening 22 on the mouth end of the cartridge 20, the heating assembly 25 is activated and steam is generated and entrained into the air flow along the air flow path 23. Optionally, the vapor is at least partially cooled within the airflow path 23 to form an aerosol within the airflow path, which is then drawn into the user's mouth through the mouthpiece end opening 22. In some configurations, the vapor is at least partially cooled in the user's mouth to form an aerosol in the user's mouth.

Interface element 30 shown in FIG. 1 is coupled to the housing 11 and is configured to detect contact with a top surface 16 of the housing 11, such as contact between the user's skin and the top surface 16. For example, the interface element 30 may include one or more contact detection elements, each located between the bottom surface 17 of the casing. Interface element 30 may optionally comprise a printed circuit board (PCB), which may be flexible and which may include said circuitry, contact detection element(s), and any light emitting element(s). Exemplary configurations for interface element 30 are proposed herein with reference to FIGS. 3 and 4A-4B, however, it should be understood that this interface element is not limited to this, and that it can be of any suitable configuration.

Each of the one or more contact detection elements is configured to generate a corresponding input signal in response to detection of contact with the top surface 16. For example, the top surface 16 of the housing 11 may have one or more regions, such as the region 18 shown in FIG. 1. Contact with the top surface 16 at or near the region 18 may actuate a contact detection element to generate an input signal. For example, the contact detection element(s) may comprise a capacitive sensor, a pressure sensor, or a temperature sensing element that generates an input signal in response to contact close enough to the region 18 to be detected.

For example, a capacitive sensor may generate an input signal corresponding to the capacitance of the capacitive sensor. Prior to contact with any relevant part of the user's body, such as a finger, palm or lip of the user, the capacitive sensor may have a first capacitance, in response to which the capacitive sensor may output a signal having a value corresponding to the absence of said contact. In response to contact with a corresponding part of the user's body that touches the upper surface 16 of the housing 11 with that part of the body, for example, in an area sufficiently close to the capacitive sensor, the capacitance of the capacitive sensor may increase or decrease to a second value, resulting in a corresponding change in the value of the signal , generated by a capacitive sensor. Based on such changes in the value of the signal generated by the capacitive sensor, the corresponding circuitry can determine that contact with the upper surface 16 of the housing 11 has occurred.

In yet another example, the pressure sensor may generate an input signal corresponding to pressure on the pressure sensor. Prior to contact with the user's finger, palm, or lip, a first pressure may be applied to the pressure sensor, in response to which the pressure sensor may output a signal having a value corresponding to the absence of such contact. In response to contact with the user's finger, palm, or lip touching the top surface 16 of the housing 11, for example, in an area sufficiently close to the pressure sensor, the pressure on the pressure sensor may increase to a second value, causing a corresponding change in the value of the signal generated by the sensor pressure. Based on such changes in the value of the signal generated by the pressure sensor, the corresponding circuitry can determine the presence of contact with the upper surface 16 of the housing 11.

In yet another example, a temperature sensing element may generate an input signal corresponding to the temperature of the temperature sensing element. Prior to contact with the user's finger, palm, or lip, the temperature sensing element may be at a first temperature, such as ambient (room) temperature or a temperature different from the ambient temperature due to heat transfer from the aerosol generating element, and in response thereto, the temperature sensing element may output a signal , having a value corresponding to such a temperature. In response to contact with a user's finger, palm, or lip touching the top surface 16 of the housing 11, for example, in an area sufficiently close to the temperature sensing element to be in thermal communication with the temperature sensing element through the housing 11, the temperature of the temperature sensing element may correspondingly increase or decrease. to the second temperature, resulting in a corresponding change in the value of the signal generated by the temperature-sensitive element. Based on such changes in the value of the signal generated by the temperature sensing element, the corresponding circuitry can determine the presence of contact with the upper surface 16 of the housing 11.

System 100 may include any suitable circuitry configured to receive an input signal from a contact detection element. In some configurations, the interface element 30 may include a separate dedicated circuit that is configured in this manner, while in other configurations the circuit 13 is configured in this manner. The circuit may be configured to generate one or more signals such as those described elsewhere herein. document, in response to receiving a corresponding input signal from each of the one or more elements for detecting contact. By way of illustration, the circuit may be configured to provide an output signal to an optional light emitting element, or it may be configured to activate a function of the aerosol generating system, or any suitable combination thereof. For example, activating a function of the aerosol generating system may include transmitting an output signal to the light emitting element. Exemplary functions of this circuit, which may, but need not necessarily, include signaling to any light emitting elements, are described with reference to FIG. 8, 9A-9C and 10A-10C.

In some configurations, interface element 30 may optionally include one or more light emitting elements, such as one or more light emitting diodes (OLEDs) or active-matrix organic LEDs. light emitting diodes, AMOLED), or plastic organic light emitting diodes, POLED, or microscopic LEDs (micro-LED). If desired, such light emitting element(s) may be configured to transmit one or more visible light signals through the housing 11, for example, in response to corresponding output signal(s), which may ) generated by the same circuit that receives the input signal(s) from the element(s) to detect the contact. For example, area 18 of housing 11 may be at least partially transparent so that the light emitting element(s) are/are capable of transmitting a visible light signal therethrough. By way of illustration, area 18 may include a recessed portion of housing 11 that is thin enough to allow a visible light signal to be transmitted therethrough.

If necessary, a material may be placed in the recessed area that is configured to change the optical properties of the visible light signal generated by one or more of the light emitting elements. For example, the material may change the focal property of the visible light signal, such as the property of focusing or defocusing the visible light signal. Said material can be profiled in such a way as to focus or defocus the visible light signal. For example, the material may have a convex shape or a concave shape, and this shape of the material may act to focus or defocus the visible light signal. Focusing or defocusing the visible light signal provides the advantage of being able to detect a lower energy visible light signal. This allows the light emitting element to consume less power when transmitting a visible light signal. Said material may be profiled before being placed in the recessed area.

The recessed area may be filled with said material. Thus, said material can be profiled according to the shape of the recessed portion. If necessary, said recessed portion may be profiled to form a profiled recessed portion. The profiled recessed area can be filled with the specified material. Thus, said material can take a shape corresponding to the shape of the profiled recessed portion. Thus, a recessed portion having a concave internal shape can be filled with said material, in which case said material assumes a convex shape corresponding to the concave shape of the recessed portion. Said material may comprise smart material that acts to focus or defocus a visible light signal.

Said material may comprise a transparent or translucent polymeric material. For example, the material may contain one or more of the following transparent or translucent compounds: polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PETG), polyvinyl chloride (PVC), polypropylene (PP), poly[2-(dimethylamino)ethyl methacrylate] (often abbreviated as PDM or PDMAEMA), styrene acrylonitrile resin (SAN), general purpose polystyrene (GPPS), liquid silicone rubber (LSR), cyclic olefin copolymer (COC) and styrene methyl methacrylate (SMMA).

Said material may be molded. This material can be remolded. This material can be 3D printed.

Alternatively, the entire housing 11 may comprise or be made from at least partially transparent material. As yet another alternative, the housing 11 may comprise a surrounding opaque material into which is embedded an at least partially transparent window defining the regions 18. Regardless of the specific configuration, the regions 18 are optionally not visible at first glance to the user in the normal state of the device.

Each of the light emitting elements may optionally be configured to generate first and second visible light signals that have different wavelengths through the at least partially transparent area 18 of the housing 11. For example, the circuit may be configured to generating first and second output signals (at different times, if necessary), which respectively lead to the generation of first and second visible light signals having different wavelengths (if necessary, at different times). ) The wavelengths may differ from each other by an amount sufficient to be perceived by the human eye, for example they may differ from each other by at least 1 nm, or by at least 5 nm, or by at least 10 nm, or by at least 20 nm, or at least 50 nm, or at least 100 nm, or at least 200 nm, or at least 300 nm.

It should be understood that the interface element 30 may be located at any suitable portion of the aerosol generating system 100, and that it is not limited to detecting contact only with the outer portion of the housing 11 or other portion of the aerosol generating device 10. For example, the interface element 30 may be located at any at a suitable location of the aerosol generating device 10 or cartridge 20, for example it may be coupled to any suitable portion of the housing 11 or housing 21 to detect contact with any suitable external portion of the system 100, such as any suitable portion of the system 100 that may be touched by a portion of the user's body, such as the lip, finger or palm during use.

In some configurations, aerosol generating system 100 includes an aerosol generating device, which may or may not include an interface element 30, and a peripheral device operably coupled to the aerosol generating device (the peripheral device is not specifically shown in FIG. 1). The peripheral device optionally includes an interface element 30, in addition to or instead of the aerosol generating device containing the interface element 30. In non-limiting configurations, the peripheral device optionally includes a charger, a charging case, a consumable holder, or a vending machine.

In some configurations, the aerosol generating system comprises an aerosol generating device, such as that described herein, and an aerosol-forming substrate, wherein the aerosol-forming substrate optionally contains nicotine.

In FIG. 2 is a schematic representation of an alternative aerosol generating system 200 comprising an interface element 30' in accordance with the present invention. The interface element 30' may include a contact detection element and an optional light emitting element, and may be configured similarly to the interface element 30 described with reference to FIG. 1. System 200 includes an aerosol generating device 10' having a housing 39, and an aerosol generating article 40, such as a tobacco stick. The aerosol-forming article 40 contains an aerosol-forming substrate 41 that is pushed inside the housing 39 to be placed in thermal proximity to the heater portion 36. In response to heating by the heater 36, the aerosol-forming substrate 41 releases a number of volatile compounds at various temperatures.

The housing 39 includes an upper surface 16', a lower surface 17', and at least one area 18'. Optionally, the top surface 16' of the housing 39 is substantially flat within the region 18'. If necessary, the housing 39 can be free of buttons, i.e. it may not contain any buttons. The top surface 16' of the housing 39 can be substantially smooth and continuous if desired. Inside the housing 39 is a source 32 of electrical power, such as a rechargeable lithium-ion battery. The controller 33 is connected to the heater 36 through electrical connections 34, and it is connected to the power source 32 and to the interface element 30' through other electrical connections. The controller 33 controls power to the heater 36 to regulate its temperature, and it operates the interface element 30' in a manner as described elsewhere herein. Typically, the aerosol-forming substrate is heated to a temperature of 250 to 450 degrees Celsius.

The housing 39 of the aerosol generating device 10' defines a cavity 39' open at the proximal end (or mouth end) for housing the aerosol generating article 40' for consumption. Optionally, the system 200 includes element(s) 37 located within the cavity 39' and, together with the casing 39, forming air inlet passages 38. The distal end of the cavity 39' is covered by a heating assembly containing a heater 36 and a heater support 35. Heater 36 is supported by heater support 35 such that the active heating region (heating portion) of heater 36 is located within cavity 39'. In one example, heater 36 includes a through hole (not specifically shown) through which heater support material 35 passes to further secure heater 36 in place. The active heating region of the heater 36 is located within the distal end of the aerosol generating article 40 when placing the aerosol generating article 40 completely within the specified cavity. The heater support 35 may optionally be made of polyetheretherketone and may be molded around the heater retaining portion. The heater 36 is optionally made in the form of a blade ending with a tip. In other words, the heater 36 optionally has a length dimension that is larger than its width dimension, which in turn is larger than its thickness dimension. The first and second ends of the heater 36 may be limited by the width and length of the heater.

An exemplary aerosol-forming article 40 shown in FIG. 2 can be described as follows. The aerosol generating article 40 includes three or more elements, namely, an aerosol generating substrate 41, an intermediate element 42, and a mouthpiece filter 43. These elements may be arranged in series, coaxially aligned, and combined via cigarette paper (not specifically shown) to form a rod. In one non-limiting configuration, the aerosol-forming article 40, when assembled, may have a length of 45 millimeters and a diameter of 7 millimeters, although it should be understood that any other suitable combination of sizes may be used.

The aerosol-forming substrate 41 optionally comprises a tow of corrugated molded sheet tobacco wrapped in Ficella (not shown) to form a plug. Said molded leaf tobacco contains one or more aerosol-forming substances, such as glycerin. An intermediate member 42 may be located in close proximity to the aerosol-forming substrate 41. The intermediate member 42 may be configured to hold the aerosol-forming substrate 41 near the distal end of the article 40 to allow it to be brought into contact with the heater 36. If necessary, the intermediate element 42 may be configured to weaken or prevent displacement of the aerosol-forming substrate 41 along the article 40 in the direction of the mouthpiece when the heater 36 is inserted into the aerosol-forming substrate 41. The intermediate element 42 may, if necessary, be configured so that volatile substances released from the aerosol-forming substrate 41, passed along the article towards the mouthpiece filter 43. Volatile substances can be cooled within the transfer section to form an aerosol. In one non-limiting configuration, the intermediate member 42 may comprise or be formed from a cellulose acetate tube directly coupled to the aerosol-forming substrate. In one non-limiting configuration, said tube defines an opening with a diameter of 3 millimeters. Optionally, the intermediate element 42 may contain a thin-walled tube or be made of an 18 millimeter long thin-walled tube directly connected to the mouthpiece filter 43. In one illustrative configuration, the intermediate element 42 contains both of these tubes. The mouthpiece filter 43 is a conventional mouthpiece filter made, for example, of cellulose acetate and having a length of approximately 7.5 millimeters. The members 41, 42 and 43 are optionally assembled by tightly wrapping them in cigarette paper (not specifically shown), such as standard cigarette paper of standard properties or classification. The paper in this particular embodiment is ordinary cigarette paper. The boundary between the paper and each of the elements 41, 42, 43 defines the position of these elements and limits the aerosol-forming article 40.

As the aerosol-generating article 40 is pushed into the cavity 39', the tapering tip of the heater 36 interacts with the aerosol-generating substrate 41. As a result of the application of force to the aerosol-generating article 40, the heater 36 penetrates into the aerosol-generating substrate 41. When the aerosol-generating article 40 is brought into interaction properly, the heater 36 penetrates the aerosol-forming substrate 42. When the heater 36 is activated, the aerosol-forming substrate 41 is heated and volatiles are generated or emitted. When a user takes a puff on the mouthpiece filter 43, air is drawn into the aerosol-forming article 40 through the air inlet ports 38, and volatiles condense to form a respirable aerosol. This aerosol passes through the mouthpiece filter 43 of the aerosol-forming article 40 and enters the user's mouth. In a similar manner as described with reference to FIG. 1, it should be understood that the interface element 30' may be located at any suitable location of the aerosol generating system 200, and that it is not limited to detecting contact only with the outer portion of the housing 39 or other portion of the aerosol generating device 10'. For example, the interface element 30 may be located at any suitable location of the aerosol generating device 10' or aerosol generating article 40, for example, it may be coupled to any suitable portion of the housing 39 so as to detect contact with any suitable external portion of the system 200, such as any suitable portion of the system 200 that may be touched by a part of the user's body, such as a lip, finger, or palm, during use.

In some configurations, the aerosol generating system 200 includes an aerosol generating device, which may or may not include an interface element 30', and a peripheral device operably coupled to the aerosol generating device (the peripheral device is not specifically shown in FIG. 2). The peripheral device optionally includes an interface element 30', in addition to or instead of the aerosol generating device containing the interface element 30'. In non-limiting configurations, the peripheral device optionally includes a charger, charging case, consumable holder, or vending machine.

Exemplary methods for manufacturing aerosol generating systems containing interface elements of the present invention are described with reference to FIGS. 5, 6A-6B and 7A-7B. Exemplary methods of using aerosol generating systems containing interface elements of the present invention are described with reference to FIGS. 8, 9A-9C and 10A-10C. It should be understood that any feature described with reference to a particular configuration may optionally be, but need not be, combined with any other features described with reference to that configuration or any other configuration described herein.

If desired, the contact detecting elements 310, 311, 312 respectively may, but need not be, superimposed on the light emitting elements 320, 321, 322. For example, the light emitting elements 320, 321, 322, if present, may be superimposed on elements 310, 311, 312 for detecting contact. In yet another example, contact detection elements 310, 311, 312, respectively, may be combined with light emitting elements 320, 321, 322 into a single structure configured to both detect contact with the top surface 302 of the housing 301 and transmit light through corresponding areas of the housing. 301. In yet another example, contact detection elements 310, 311, 312 and/or light emitting elements 320, 321, 322 may be incorporated into the housing 301.

In FIG. 4A-4B are respectively a sectional view and a perspective view of yet another illustrative interface element 400. The interface element 400 may be suitably implemented as a non-limiting example of an interface element 30, 30' or 300. The housing 401 shown in FIG. 4A-4B, is provided in any suitable component of the aerosol generating system, and may be, but need not be, part of the interface element 400. The housing 401 includes an upper surface 402, a lower surface 403, and a plurality of areas 450, 451, 452 that optionally are at least partially transparent. In a non-limiting example shown in FIG. 4A-4B, discrete regions 450, 451, 452 of the housing 401 are thinner than other areas of the housing 401, for example, they are thin enough to transmit a visible light signal, while other areas of the housing 401 are, if necessary, thick enough. so that no visible light signal is transmitted through them. In a non-limiting example, regions 450, 451, 452 include recessed portions 460, 461, 462 of housing 401.

Interface element 400 shown in FIG. 4A-4B, comprises a plurality of input/output elements 470, 471, 472, each of which includes a contact detection element (not specifically shown) and a light emitting element (not specifically shown), which respectively may be configured as described elsewhere. places in this document.

For example, in the non-limiting configuration shown in FIG. 4A-4B, the recessed portions 460, 461, 462 are curved such that the at least partially transparent material 490 disposed therein acts as a lens that modifies the focal properties of the visible light signal generated by the input elements 470, 471, 472 - conclusion. By way of illustration, said at least partially transparent material 490 causes the visible light signal to be focused or defocused. Flexible printed circuit board 480 may be suitably coupled and optically integrated with I/O elements 470, 471, 472 and optional circuitry (not specifically shown) to receive input signals from contact detection elements and transmit output signals to light emitting elements such as described elsewhere in this document. If desired, flexible printed circuit board 480 may be coupled to control circuitry (e.g., 13 or 33) of the aerosol generating system, for example, through one or more interconnects 491. Interface elements proposed herein may contain any suitable number of detection elements contact and any suitable number of optional light emitting elements. For example, although each of the illustrative interface elements shown in FIG. 3, 4A and 4B comprises three elements for contact detection (in the form of three I/O elements in FIGS. 4A-4B), it should be understood that any interface element proposed herein, including, without limitation, interface element 30 , 30', 300 or 400, may suitably comprise one contact detecting element or more than one contact detecting element. For example, any interface element proposed herein may comprise two or more contact detection elements, five or more contact detection elements, or ten or more contact detection elements. For example, any interface element proposed herein may contain from one to fifty elements for contact detection, or from one to twenty elements for contact detection, or from two to twenty elements for contact detection, or from five to twenty elements for detection contact, or from five to fifteen elements for contact detection. If necessary, although the illustrative interface elements shown in FIG. 3, 4A and 4B are shown as comprising three light emitting elements (in FIGS. 4A-4B as three I/O elements), it is understood that any interface element provided herein, including, without limitation, element 30, 30', 300 or 400 may suitably comprise one or more contact detecting elements and zero or more light emitting elements. For example, any interface element provided herein may comprise two or more light-emitting elements, five or more light-emitting elements, or ten or more light-emitting elements. For example, any interface element provided herein may contain from one to fifty light emitting elements, or from one to twenty light emitting elements, or from two to twenty light emitting elements, or from five to twenty light emitting elements, or from five to fifteen light emitting elements. elements. In some configurations, the interface element does not contain any light-emitting elements.

Any interface element provided herein may include contact detection element(s) and optional light emitting element(s) in any suitable arrangement in the aerosol generating system. For example, a plurality of contact detection elements may be arranged transversely in a two-dimensional array along the housing so as to provide or form a regular shape, such as a polygon (e.g., rectangle, square, triangle, pentagon, hexagon, or the like) or curved shape (for example, circle or oval). For example, a two-dimensional array of contact detection elements may be arranged to provide or form a rectangle such as that shown in FIG. 9A-9B or 10A-10B. In yet another example, a plurality of light emitting elements may be arranged transversely in a two-dimensional array along the housing so as to provide or form a regular shape, such as a polygon (e.g., rectangle, square, triangle, pentagon, hexagon, or the like) or curved shape (for example, circle or oval). For example, a two-dimensional array of light emitting elements may be arranged to provide or define a rectangle such as that shown in FIG. 9A-9B or 10A-10B. Optionally, the contact detecting elements and the light emitting elements (if present) are arranged substantially identically with each other. By way of illustration, each contact detection element and any corresponding light emitting element may optionally be rigidly connected to each other such that they are partially or completely immovable relative to each other before or after installation in the device. If desired, all of the plurality of contact detecting elements may be rigidly coupled to each other, if desired, such that they are partially or completely immovable relative to each other before or after installation in a component of the aerosol generating system.

Regardless of the specific manner in which the contact detection element(s) and any other elements of the interface element are coupled to each other, the interface element may be included in any suitable component of an aerosol generating system, including, without limitation, an aerosol generating device or peripheral device, and into any suitable element of such a component. The aerosol generating system may include an aerosol generating device that includes an interface element, for example a device such as device 10 or 10', and it may optionally contain one or more peripheral devices. Examples of peripheral devices that may be included in the aerosol generating systems of the present invention include, but are not limited to, one or more of the following: a charger for an aerosol generating device, a charging case for an aerosol generating device, a holder for one or more aerosol generating articles, or a vending machine configured to sell aerosol-generating devices or aerosol-generating products. If desired, one or more such peripheral devices may include an interface element of the present invention. In some configurations, the interface element has a uniform appearance and/or uniform functionality across each aerosol generating device or peripheral device (if any) in which the interface element is included.

Aerosol generating systems containing the interface elements of the present invention can be manufactured by any suitable method. In FIG. 5 shows a flowchart of an exemplary method 50. FIG. 6A to 6B respectively show schematically a sectional view and a perspective view of the intermediate structure obtained by performing the process of FIGS. 5. In FIG. 7A to 7B respectively show schematically a sectional view and a perspective view of another intermediate structure obtained by performing the process of FIG. 5.

Although the operations of method 50 are described with reference to elements of aerosol generating systems 100 and 200, elements of interface elements 300 and 400, and elements of intermediate structures such as those shown in FIG. 6A-6B and 7A-7B, it should be understood that these operations can be performed to manufacture any other suitably configured aerosol generating systems, aerosol generating devices, peripheral devices or interface elements.

Method 50 includes providing a housing comprising an upper surface, a lower surface, and an at least partially transparent area extending between the upper surface and the lower surface (step 51). The housing may be part of any suitable component of the aerosol generating system, such as part of an aerosol generating device or peripheral device such as those described with reference to FIGS. 1 and 2. The aerosol generating system may comprise an aerosol generating element configured to generate an aerosol using any suitable aerosol-forming substrate, such as a liquid, gel or solid substrate. Optionally, the housing is characterized by any suitable combination of the following: flat, smooth, buttonless, and continuous.

In some non-limiting configurations, the illustrated operation 51 of method 50 may include making an indentation in a portion of the casing to form an at least partially transparent area. In the non-limiting example of FIG. 6A-6B show an intermediate structure that may be formed in step 51 and includes regions 650, 651, 652 containing recessed portions 660, 661, 662 of housing 601, similar to regions 450, 451, 452 described with reference to FIG. 4A-4B. Step 51 may optionally include providing such recessed portions 660, 661, 662 in the bottom surface 603 of the casing 601. In one non-limiting example, forming the recessed portion of the casing includes laser ablation of the recessed portion of the casing, such as laser ablation of the bottom surface 603 with a laser. By way of illustration, cavities of a specific shape (such as curved or polygonal) can be created by laser ablation in the inner (bottom) surface of the housing, for example in areas in which contact detection elements and optional light emitting elements are to be placed. Such laser ablation may optionally be performed to the extent that the material is partially transparent in areas 650, 651, 652, the level of transparency being selected such that the material appears opaque unless a visible light signal is transmitted through it . The curved sides of the recessed areas 660, 661, 662 may provide a gradient of transparency around the corresponding areas 650, 651, 652.

Let us turn again to Fig. 5, wherein method 50 includes providing an interface element (step 52). The interface element may include a contact detection element configured to generate an input signal in response to contact with the top surface being detected by the contact detection element. Non-limiting exemplary configurations of elements for contact detection are described elsewhere herein, for example with reference to FIG. 1, 2, 3 and 4A-4B.

Optionally, providing an interface element (step 52) includes providing a light-emitting element configured to transmit a visible light signal through the at least partially transparent area in response to an output signal. For illustration, a light emitting element may be located below the bottom surface. Non-limiting exemplary light emitting element configurations are described elsewhere herein, for example with reference to FIGS. 1, 2, 3 and 4A-4B.

In some configurations, such as those in which the method 50 includes providing a light emitting element, and in those in which the at least partially transparent area is formed by providing a recess, the step of placing material on the recessed portion of the housing may also be included. . Said material may be configured to change the optical properties of the visible light signal generated by the light emitting element. In the non-limiting example of FIG. 7A-7B illustrate an intermediate structure that may be formed by such an operation, in which material 690 is located within recessed portions 660, 661, 662 of housing 601 in a configuration similar to material 490 described with reference to FIG. 4A-4B. If necessary, this material is also located on other areas of the bottom surface 603. In one non-limiting example, a thin layer of transparent material is applied vertically, such as clear varnish, when the inner (bottom) surface is substantially horizontal, so that the material 690 fills the recesses, and so Thus, any material covering the bottom surface 603 is substantially flat. The transparent material can be dried and, if necessary, polymerized or covered with a mesh to obtain a stable shape or configuration. By way of illustration, this may result in the formation, at each of the recessed portions, of a magnifying lens which can focus or defocus any visible light signals respectively transmitted therethrough.

Method 50 shown in FIG. 5 includes connecting said circuitry to an interface element, such as a contact detection element and (if present) a light emitting element (step 53). The said circuit may be configured to receive an input signal from a contact detection element and transmit an output signal to any light emitting element. For example, in some configurations, such as those described with reference to FIGS. 3 and 4A-4C, a contact detection element and (if present) a light emitting element are optionally connected to said circuitry provided as part of an interface element, and said circuitry is configured to communicate with control circuitry of the aerosol generating system or device. Alternatively, the contact detection element and (if present) the light emitting element may be coupled to the control circuitry of the aerosol generating device without the aid of such circuitry. Any other suitable circuit may be connected to one or both of the contact detection element and the light emitting element. For example, in a manner as described in FIG. 4A-4B, flexible printed circuit board 480 may be suitably coupled to and optionally integrated with input/output elements 470, 471, 472 and may include optional circuitry (not specifically illustrated) for receiving input signals from the contact sensor element(s) and transmitting output signals to any light emitting element(s) in a manner as described elsewhere herein.

In one configuration, I/O elements 470, 471, 472 may be provided on (combined with) flexible circuit board 480 using any suitable operations, such as using any suitable combination of semiconductor processing, printed lithography, and microlithography. Flexible printed circuit board 480 may comprise one or more polymeric materials, which may be coated with at least one layer comprising polymeric and/or metallic materials to form a layered structure. If necessary, thin film electroluminescent display technology that contains light sources and sensors can be used. The flexible printed circuit board 480 may be configured to be positioned relative to the recessed portions 660, 661, 662 to geometrically align the light emitting elements with the centers of the respective recessed portions. The flexible printed circuit board may be mechanically coupled to the housing, or it may be attached with an adhesive, such as an adhesive coating applied in areas outside of the recessed portions 660, 661, 662.

Aerosol generating systems, aerosol generating devices, peripheral devices and interface elements, such as those described herein, may be configured and used in any suitable manner to receive information from a user and/or to transmit information to a user.

For example, any of the aerosol generating systems proposed herein (such as systems 100 or 200) may comprise a housing that includes an upper surface, a lower surface, and a plurality of regions (eg, housing 11, 21, 39, 401, or 601). The aerosol generating system may include a plurality of contact detection elements (such as contact detection elements 310, 311, 312 or input/output elements 470, 471, 472). The contact detection elements may be configured to generate a corresponding input signal in response to detection of contact with the top surface of the housing in a corresponding one of the regions (such as regions 350, 351, 352, or regions 450, 451, 452, or regions 650, 651 , 652) or near it. The aerosol generating system may include circuitry configured to receive appropriate input signals from elements for contact detection (such as control circuit 13, control circuit 33, or circuit 330). Said circuitry may optionally be further configured to activate a first function of the aerosol generating system in response to a first plurality of corresponding input signals satisfying the first criterion.

Any suitable function of the aerosol generating system may be activated by said circuitry in response to satisfaction of any suitable criterion or criteria, for example in response to any suitable number of appropriate input signals satisfying any suitable criterion or criteria. Satisfaction of such criterion or criteria may be considered in terms of user authentication to the aerosol generating system. In some configurations, the aerosol generating system can be configured to authenticate a user using a one-step procedure. In other configurations, the aerosol generating system may be configured to authenticate a user using a multi-step procedure, such as a two-step authentication procedure or a three-step authentication procedure.

An exemplary multi-step procedure that may be implemented by an aerosol generating system may include detecting a user interaction and determining whether the interaction is an interaction with an approved user or type of user. Such determination may include, for example, any suitable combination of one or more of the following: comparing the thermal contact area with a stored thermal contact area value; using an array of sensors (such as contact sensors) to detect contact; using a fingerprint sensor to receive a fingerprint and compare that fingerprint with a stored fingerprint; or the use of voice recognition technology, whereby, for example, the system asks the user a question, receives a voice sample from the user in response to said question, and compares that voice sample with previously stored voice information (for example, to determine that the voice frequency is below a certain frequency and /or belongs to a specific user, or another determination is made, such as typically performed in telephone banking technology). As a result of or depending on this determination, in some configurations the system may also either take no further action (e.g. if the user is not approved or is not an approved type of user), or it may be activated to accept additional input from the user, e.g. second input data from the user in the form of some expected information that is stored in memory and may be or contain any suitable combination of one or more of the following: a password or a code (for example, a touch combination entered by the user by touching the various indicator lights of the interface element herein invention, or a code or password entered using the touch screen or buttons); or a voice command (for example, entered by the user saying a specific word out loud, or similar to technology used in telephone banking, where the user's voice is identified as belonging to that user and not someone else). If the input from the user matches the expected input from the user, then activation of the aerosol generating system or component thereof is permitted, in particular activation of the aerosol generating element. If the input data from the user is incorrect, then activation of the aerosol generating element is blocked. Accordingly, various user input means may be included in any suitable component or components of the aerosol generating system, including any suitable one or more aerosol generating device or peripheral device.

In FIG. 9A-9C and 10A-10C schematically illustrate illustrative embodiments of the interface elements of the present invention. Interface elements may be provided in any suitable component of the aerosol generating system.

Exemplary functions that may be activated by the circuit include, but are not limited to, activating an aerosol generating element of the system or initiating an authentication procedure. Optionally, said first criterion includes said circuit receiving a predetermined number of respective input signals simultaneously with each other. For example, in FIG. 9A-9C illustrate a device 900, such as an aerosol generating device or a peripheral device of an aerosol generating system, that includes an interface element of the present invention including a plurality of contact detection elements (not specifically shown) and, optionally, a plurality of light emitting elements 920. Detection elements contacts may be distributed within any suitable area of device 901. For example, as shown in FIG. 9A, before detecting contact of a user's body part, such as a finger, palm, or lip, with the upper (outer) surface of the housing 901 of the device 900, one or more functions of the device may be deactivated by circuitry (not specifically shown). For example, one or more unauthorized users may be prohibited from using one or more features of the device. As shown in FIG. 9B, the user's finger(s) or palm 910 may contact the top surface of the housing 901. A plurality of contact detection elements may detect such contact, and in response thereto, they may generate corresponding input signals that are transmitted to the circuitry. The specified circuit is configured to determine whether the received signals satisfy a predetermined criterion, for example, whether the specified number of signals is received by the specified circuit. Said predetermined number, in one non-limiting example, may be the number of signals expected to be generated in response to contact of the top surface of the housing 901 with the hand of a particular user or an approved type of user.

In one non-limiting example, said predetermined amount may correspond to a contact covering greater than 30% of the surface area of the housing, preferably greater than 40% of the surface area of the housing, preferably greater than 50% of the surface area of the housing, or preferably greater than 60% of the surface area of the housing, and for this purpose, under The surface area of the casing can only be understood as the area of the top (outer) surface, and not the area of the entire outer surface, covering all the outer sides of the aerosol generating system. This or any other suitable criterion or criteria may provide or form part of an authentication procedure.

As shown in FIG. 9C, the circuit determines that the received signals satisfy a criterion, for example, that the number of signals received by the circuit corresponds to the number of signals expected to be generated when the top surface of the housing 901 contacts a specific user or an approved type of user. In response to determining that the received signals satisfy said criterion, said circuitry activates a first function of the aerosol generating system. For example, in FIG. 9C, the first function activated by said circuit is optionally generating visible light signals from a plurality of light emitting elements.

Activation of such a function may include, for example, said circuitry transmitting a corresponding output signal to a first plurality of light emitting elements (e.g., a given subset or all light emitting elements) to cause said plurality of light emitting elements to transmit corresponding visible light signals through corresponding areas such as those shown in FIG. 9C.

Said circuit may use any other suitable criterion to activate the appropriate function of the aerosol generating system. In yet another example, the criterion involves the circuit receiving specified input signals in a specified sequence. For example, in a device 1000 (eg, an aerosol generating device or a peripheral device of an aerosol generating system) configured as shown in FIG. 10A, a plurality of light emitting elements (eg, a given subset or all of the light emitting elements) generate respective visible light signals, as necessary, in response to operations such as those described with reference to FIG. 9A-9C. The user can touch areas of the upper surface of the housing 1001 corresponding to predetermined contact detection elements in a predetermined sequence, causing the contact detection elements to generate corresponding input signals in a predetermined sequence. Said predetermined sequence of corresponding input signals may be regarded as an authentication code, and may optionally be predefined by the user and stored in a computer readable memory operatively associated with said circuit.

Said circuitry may be configured to activate a second function of the aerosol generating system in response to receiving said predetermined sequence of appropriate input signals. For example, one or more additional or different light emitting elements may (or may not) generate visible light signals, or one or more wavelengths of such visible light signals may be changed. For example, as shown in FIG. 10B, said circuit generates predetermined visible light signals from among those indicated in response to receiving a predetermined sequence of corresponding input signals. This circuitry may optionally enable activation of one or more additional functions of the aerosol generating system in response to satisfaction of one or more additional criteria. For example, another criterion may include said circuit receiving specified input signals from among those specified in a second specified sequence. For example, the user may again touch areas of the upper surface of the housing 1001 corresponding to predetermined contact detection elements among those in a predetermined sequence, causing the contact detection elements to generate corresponding input signals in a predetermined sequence. Optionally, the contact detection elements belonging to this predetermined sequence correspond to light emitting elements that generate visible light signals in FIG. 10V. In response to receiving this specified sequence, any additional function may be activated. For example, as shown in FIG. 10C, said circuitry causes specified light emitting elements from among them to generate visible light signals in response to receiving said predetermined sequence of corresponding input signals. In this non-limiting example, the same light emitting elements generate light signals as shown in FIG. 10B, however, the visible light signals generated by one or more of such light emitting elements differ in color from each other.

In yet another example, a function that can be activated by the circuitry in response to satisfaction of any suitable criterion, such as one or more of the criteria described with reference to FIG. 9A-9C and 10A-10C (any of which may be considered a criterion to provide an authentication procedure and, if necessary, may be predefined by the user and stored in a computer-readable memory operably coupled to said circuitry) includes activating an aerosol generating element of the aerosol generating system.

For illustration, in FIG. 8 shows a flowchart of an exemplary method of using an aerosol generating system. Method 80 shown in FIG. 8 may include generating, through a plurality of contact detection elements (such as contact detection elements 310, 311, 312 or input/output elements 470, 471, 472), a plurality of input signals in response to detection of contact with the top surface of the housing at corresponding areas of the casing or near them (step 81). Method 80 shown in FIG. 8 may also include receiving, through a circuit (such as control circuit 13, control circuit 33, or circuit 330), said plurality of input signals (step 82). Method 80 may also include said circuitry activating a function of the aerosol generating system in response to a plurality of input signals satisfying the criterion (step 83). Exemplary features and exemplary criteria are described elsewhere in this document.

Thus, the aerosol generating systems, interface elements and methods of the present invention provide the ability to reduce or eliminate the use of buttons or other mechanical interface elements.

Optionally, the aerosol generating systems, interface elements, and methods of the present invention enable secure use of the aerosol generating system after an authentication process. Optionally, the aerosol generating systems, interface elements and methods of the present invention may be user configurable, such as allowing the user to define contact sequences with the top surface of the casing that can be used to activate one or more functions of the aerosol generating system.

Although certain interface element configurations of the present invention have been described in relation to an aerosol generating system comprising an aerosol generating device and a separate but attachable aerosol generating article, it should be understood that the interface elements can suitably be provided in a single component aerosol generating system.

It should also be understood that alternative configurations are possible within the scope of the present invention. For example, the interface elements of the present invention can be suitably incorporated into any type of device or system, and are not limited to use in aerosol generating devices and systems. By way of illustration, interface elements of the present invention may be included in medical devices, smartphones, or the like.
