An aerosol delivery device includes a chamber for receiving an article including an aerosolizable material for delivery by the aerosol delivery device, a transmitter, a receiver spaced apart from the transmitter, and a processor. The processor is configured to: cause the transmitter to transmit a first signal to the receiver at least partially through an article in the chamber in use, so that the receiver receives a second signal, wherein the second signal is the first signal altered by interaction with a signal altering component of the article, and determine article data from the second signal. An article includes an aerosolizable material; and a signal altering component. The signal altering component is configured to alter a first signal transmitted at least partially through the article into a second signal indicative of article data.

An aerosol generating apparatus, especially a personal vaporizer device such as an electronic smoking article, generates an aerosol from a source of aerosol-forming substance. The aerosol generating apparatus includes a receiving portion configured to receive a consumable unit, such as a charge or cartridge including a source of aerosol-forming substance, and at least one locating member for locating the consumable unit within the receiving portion. The at least one locating member is configured to locate or position the consumable unit within the receiving portion such that an airflow path extends along outer sides of the consumable unit and through the consumable unit entering at one end region thereof and exiting from an opposite end region thereof, with the outer sides of the consumable unit being arranged between the one end region and the opposite end region.

A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.

An article for use in a non-combustible aerosol provision system includes an aerosol-generating component circumscribed by a first wrapping material including a cellulose based material. The cellulose based material can have a basis weight greater than about 40 grams per square metre. There is also described a rod of aerosol-generating material having a length of less than 30 mm and wrapped in a first wrapping material and an outer wrapping material which extends at least partially over the rod of aerosol-generating material. There is also described a rod of aerosol-generating material wrapped in a first wrapping material and an outer wrapping material which extends over the rod of aerosol-generating material by a distance of between about 30% and 80% of the length of the rod of aerosol-generating material. A non-combustible aerosol provision system is also described.
