Detailed Description As used herein, the term "aerosol delivery device" is intended to encompass systems that deliver a substance to a user, and includes:
non-combustible aerosol provision systems that release compounds from an aerosolisable material without combusting the aerosolisable material, such as electronic cigarettes, tobacco heating products, and hybrid systems to generate aerosol using a combination of aerosolisable materials; and articles comprising aerosolisable material and configured to be used in one of these non-combustible aerosol provision systems.
According to the present disclosure, a "combustible" aerosol provision system is one where a constituent aerosolisable material of the aerosol provision system (or component thereof) is combusted or burned in order to facilitate delivery to a user.

- 4 -According to the present disclosure, a "non-combustible" aerosol provision system is one where a constituent aerosolisable material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery to a user.
In embodiments described herein, the delivery system is a non-combustible aerosol provision system, such as a powered non-combustible aerosol provision system.
In one embodiment, the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosolisable material is not a _ro requirement.
In one embodiment, the non-combustible aerosol provision system is a tobacco heating system, also known as a heat-not-burn system.
In one embodiment, the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosolisable materials, one or a plurality of which may be heated. Each of the aerosolisable materials may be, for example, in the form of a solid, liquid or gel and may or may not contain nicotine. In one embodiment, the hybrid system comprises a liquid or gel aerosolisable material and a solid aerosolisable material. The solid aerosolisable material may comprise, for example, tobacco or a non-tobacco product.
Typically, the non-combustible aerosol provision system may comprise a non-combustible aerosol provision device and an article for use with the non-combustible aerosol provision system. However, it is envisaged that articles which themselves comprise a means for powering an aerosol generating component may themselves form the non-combustible aerosol provision system.
In one embodiment, the non-combustible aerosol provision device may comprise a power source and a controller. The power source may be an electric power source or an exothermic power source. In one embodiment, the exothermic power source comprises a carbon substrate which may be energised so as to distribute power in the form of heat to an aerosolisable material or heat transfer material in proximity to the exothermic power source. In one embodiment, the power source, such as an exothermic power source, is provided in the article so as to form the non-combustible aerosol provision.

- 5 -In one embodiment, the article for use with the non-combustible aerosol provision device may comprise an aerosolisable material, an aerosol generating component, an aerosol generating area, a mouthpiece, and/or an area for receiving aerosolisable material.

In one embodiment, the area for receiving aerosolisable material may be separate from, or combined with, an aerosol generating area.
Aerosolisable material, which also may be referred to herein as aerosol generating material, is material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosolisable material may, for example, be in the form of a solid, liquid or gel which may or may not contain nicotine and/or flavourants. In some embodiments, the aerosolisable material may comprise an "amorphous solid", which may alternatively be referred to as a "monolithic solid" (i.e.
non-fibrous). In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it.
The aerosolisable material may be present on a substrate. The substrate may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted aerosolisable material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy.

FIG. 3 is a flow chart showing an algorithm, indicated generally by the reference numeral 30, in accordance with an example embodiment.
The algorithm 30 starts at operation 32, where a determination is made regarding whether the lid 12 of the case lo has been opened. If not, the algorithm 30 moves to operation 36 where the algorithm 30 terminates.
If it is determined in the operation 32 that the lid has been opened, then the algorithm 30 moves to operation 34 where first diagnostics are performed. Example diagnostics are discussed further below.
Similarly, FIG. 4 is a flow chart showing an algorithm, indicated generally by the reference numeral 40, in accordance with an example embodiment.
The algorithm 40 starts at operation 42, where a determination is made regarding whether the lid 12 of the case lo has been closed. If not, the algorithm 40 moves to operation 46 where the algorithm 40 terminates.
If it is determined in the operation 42 that the lid has been closed, then the algorithm 40 moves to operation 44 where second diagnostics are performed. Example diagnostics (which may be partially or totally different to the first diagnostics referred to above) are discussed further below.
Of course, the algorithms 30 and 40 shown in FIGS. 3 and 4 are highly schematic and may be implemented in many different ways. For example, the algorithms 30 and may be implemented as interrupt routines, wherein the detection of the lid changing from a closed state to the opened state or vice-versa triggers the relevant diagnostics.

- 9 -Moreover, one or other of the algorithms 30 and 40 may be omitted; thus diagnostics may be performed when the lid is opened (algorithm 30) but not when it is closed (algorithm 40), or vice-versa.
FIG. 5 is a block diagram of a system, indicated generally by the reference numeral 50, in accordance with an example embodiment.
The system 50 shows the lid 12 and the main body 14 of the case described above. The system 50 also shows a switch 52 that is used to determine when the lid 12 is opened or closed. The switch 52 is one example of many arrangements for determining whether the lid 12 is opened or closed. Other examples include a magnet/hall sensor pairs or the detection of an impedance change.

The sensor 62 provides a signal to the controller 64 indicative of whether the lid is open or closed. The switch 52 described above is one example implementation of the sensor 62 but, as noted above, many alternatives (such as the use of a hall sensor/magnet pair) are possible.
The controller 64 is configured to activate diagnostics depending on the lid signal. For example, the controller 64 may be configured to activate first diagnostics when the lid signal indicates a change from lid being closed to the lid being open.
Alternatively, or in addition, the controller 64 may be configured to activate second diagnostics when the lid signal indicates a change from lid being open to the lid being closed.
Thus, the controller 64 may implement the algorithm 30 and/or the algorithm 40 described above.
The first and second diagnostics may take many forms. Moreover, the first and second diagnostics may be the same, partially the same or different.

- 10 -By way of example, examples of the first diagnostics (performed when the lid is opened) include: device health diagnostics; session data; and fault information.
Examples of the second diagnostics include: battery charge level; and device readiness.
The system 60 may comprise a display 66 for providing information relating to diagnostics. FIGS. 7 and 8 are block diagrams of displays in accordance with example embodiments.
