Abstract: A method of operating an aerosol generating apparatus is disclosed. The method includes sensing, at a first sensor of a sensor arrangement, a first indicia of an article including aerosolizable medium; sensing, at a second sensor of the sensor arrangement spaced a predetermined distance from the first sensor, a second indicia of the article; determining a distance between the first indicia and the second indicia; and operating the aerosol generating apparatus based at least on the distance between the first indicia and the second indicia.

Abstract: An electronic vapor provision system includes a control unit configured to provide power from a battery in the control unit to components of the system, and including a controller configured to control components of the system; and an aerosolizable substrate material carrying portion separably connectable to the control unit to obtain power from the battery, and including a first electrical circuit including a characteristic-carrying element; and a second electrical circuit including a vapor generating element configured to generate an inhalable vapor from an aerosolizable substrate material; wherein: the second electrical circuit can be selectively provided with power from the battery when power is supplied to the aerosolizable substrate material carrying portion; and the controller is configured to operate in a first mode in which a characteristic of the characteristic-carrying element is determined by providing power from the battery to the first electrical circuit, and in a second mode in which the vapor

Abstract: An aerosol provision device is configured to couple to a consumable component, and includes a transceiver configured for connection of the device to a communications network; and a processor configured to: obtain identification information from a consumable component engaged with the device, the identification information being uniquely provided to the consumable component or to a group of consumable components to which the consumable component belongs; configure the identification information as an identifier for the consumable component; send, via the communications network, an authorization query including the identifier to a remote server holding a list of one or more authorized identifiers; receive, via the communications network, an authorization response to the authorization query from the remote server; and identify the consumable component as authorized if the authorization response indicates that the identifier is comprised in the list of authorized identifiers.

Abstract: 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.

Abstract: An aerosol generating device for receiving an aerosol generating article includes an electrical circuit including a controller for determining a change in an electrical property of the circuit. The change in the electrical property of the circuit is caused by the user interacting with an aerosol generating article received by the device.

Abstract: An apparatus for generating aerosol from an aerosolizable medium is disclosed. The apparatus includes a housing; a chamber for receiving an article, a sensor and a cover system. The article includes an aerosolizable medium and a detectable element provided in association with the article. The sensor is configured to sense the detectable element when an article is received within the chamber. The cover system can be configured in at least a first configuration to substantially cover the sensor, and a second configuration, in which a field of view of the sensor is substantially without obstruction.

Abstract: An apparatus for generating aerosol from an aerosolizable medium is disclosed. The apparatus comprises: a housing; a chamber for receiving an article comprising aerosolizable medium and including a marker; and a controller. The controller is configured to receive: a first input indicative of a rate of movement of the article, received in use, in the chamber; and a second input indicative of a parameter of said article. At least the second input is determined based on the marker.

Abstract: A control device for an electronic aerosol provision system is provided. The control device is configured to receive a replaceable component to form an electronic aerosol provision system. The control device includes a communication interface for performing communications external to the electronic aerosol provision system; a memory configured to hold a set of stored identifiers; and a control system. The control system is configured to: receive control information from a remote server via the communication interface; update the set of stored identifiers based on the control information received from the remote server; receive an identifier from a replaceable component received by the control device; make a comparison of the received identifier against the set of stored identifiers; and perform a control action for the electronic aerosol provision system dependent upon the result of said comparison.

Abstract: An electronic vapor provision system includes a vaporizer for vaporizing a payload for inhalation by a user of the electronic vapor provision system, the vaporizer taking a finite period of time from having power supplied to it to vaporize the payload; a power supply for supplying power to the vaporizer to vaporize the payload in response to a user activation; one or more sensors operable to output respective signals in response to interaction of the user with the electronic vapor provision system; an estimation processor configured to estimate a user's expected moment of activation, based upon analysis of one or more of the respective signals; and a control processor configured to cause power to be supplied to the vaporizer at a time that precedes the user's estimated expected moment of activation.
