  • the article control circuitry 38 then prevents the supply of electrical power to the aerosol generator 36 by opening the switch 310, thereby breaking the circuit between the connectors 31a.
  • other means of controlling the electrical power supplied to the aerosol generator 36 may be employed, such as through the use of logic gates, variable resistance and/or variable current. In any of these cases, the supply of power can be interrupted during a puff based on the power supply control data described above, for instance based on an aerosol-generating profile which is adopted by the article control circuitry 38.

Additionally or alternatively, if the measured temperature is above a threshold temperature while the article control circuitry 38 is controlling the supply of power to the aerosol generator, the power level can be reduced.
  • the puff sensor 41 can provide an indication to the article control circuitry 38 each time a user puffs on the device 20.
  • the puff sensor 41 can, for instance, be a sensor detecting a change in air pressure or airflow through the air channel 23, a sensor detecting the user's lips on the mouthpiece 35, and/or a sensor detecting a change in orientation of the article 30.

  • the power supply control data or aerosol-generating profile can be altered such that the amount of power supplied to the aerosol generator 36 over a period of time is reduced.
  • a lower power level can be supplied to the aerosol generator 36 during the second user puff than would otherwise have been the case, for instance since it can be predicted that the aerosol generator 36 and/or aerosol-generating material 32 will have a higher temperature at the start of the second puff than if a longer time has elapsed.

  • the article control circuitry 38 can be configured to update the value of the counter in response to the inhalation.
  • the value of the counter can be updated by incrementing or decrementing the value of the counter depending on the exact implementation of the counter, for example by a value of one for each inhalation performed by the user.
  • a user may perform multiple inhalations within a short period of time, and the article control circuitry 38 may be configured to update the value of the counter periodically (for example every 10 seconds, every minute, 5 minutes or 10 minutes) to reflect the number of inhalations performed in that time period, rather than updating the counter in response to each inhalation.
  • the article control circuitry 38 can also be configured to prevent electrical power from being supplied to the aerosol generator 36 based on a comparison between the value of the counter and an inhalation limit.
  • the inhalation limit represents the point at which the article 30 needs to be refilled. For example, there may be a maximum number of inhalations that can be performed on the aerosol provision system 10 by a user of the aerosol provision system 10 until the aerosol-generating material 32 in the aerosol-generating material storage area 39 is depleted and the article 30 needs to refilled (for example 50, 100, 500 or 1000).
  • the article control circuitry 38 can be configured to compare the value of the counter to an inhalation limit, and prevent electrical power from being supplied to the aerosol generator 36 when the inhalation limit has been reached, for example by actuating (opening) the switch 310, or maintaining the switch 310 in the open position.

  • the article control circuitry 38 can update the value of the counter to a reset value. For example, in the case described above where the value of the counter is incremented in response to an inhalation on the aerosol provision device 10 by the user of the aerosol provision device 10, the reset value can be zero, and the article control circuitry 38 is then configured to update the value of the counter to zero.

  • the article 30 is not completely filled with aerosol-generating material 32.
  • aerosol-generating material 32 is transferred to the aerosol-generating material storage area 39, but the aerosol-generating material storage area 39 does not reach its capacity.
  • the article control circuitry 38 can update the value of the counter to a reset value that reflects the amount of aerosol-generating material 32 in the aerosol-generating material storage area 39.
  • the reset value is selected by the article control circuitry 38 based on the amount of aerosol-generating material 32 transferred to the aerosol-generating material storage area 39 so that the number of inhalations required before the value of the counter reaches the inhalation limit is reflective of the amount of aerosol-generating material 32 in the aerosol-generating material storage area 39.
  • the article control circuitry 38 can be configured to determine the amount of aerosol-generating material 32 transferred to the aerosol-generating material storage area 39 using similar methods as described above, such as using a sensor or receiving a notification from the refilling device indicating the amount of aerosol-generating material 32 that was is transferred to the aerosol-generating material storage area 39.
  • the article control circuitry 38 can also be configured to enable the supply of electrical power to the aerosol generator 36 in response to the value of the counter being updated to the reset value. Since updating the value of the counter to the reset value indicates that aerosol-generating material 32 has been transferred into the aerosol-generating material storage area 39, it is therefore safe to supply electrical power to the aerosol generator 36. Accordingly, the article control circuitry 38 can be configured to enable the supply of electrical power to the aerosol generator 36 in response to the value of the counter being updated to the reset value, for example by closing the switch 310.

As described above, if the value of the counter is equal to the reset value or has not reached the inhalation limit, the article control circuitry 38 enables the supply of electrical power to the aerosol generator 36 (for example by closing the switch 310). If the value of the counter is equal to (ie has reached) the inhalation limit, the article control circuitry 38 prevents the supply of electrical power to the aerosol generator 36 (for example by opening the switch 310).
  • the article control circuitry 38 may actuate (close) the switch 310 in response to the value of the counter being updated to the reset value, but the device control circuitry 28 is configured to only enable the supply of electrical power from the battery 14 to the aerosol generator 36 in response to detecting an inhalation.
  • the device control circuitry 28 may enable the supply of electrical power from the battery 14 to the aerosol generator 36 by actuating a second switch separate to the switch on the article 30 (for example location on the aerosol provision device 20).

In other words, when the article 30 is new the aerosol generator 36 is disabled and cannot be used until the value of the counter is updated away from the initial value.
  • Preventing electrical power from being supplied to the aerosol generator 36 when the value of the counter equals the initial value ensures that the article 30 cannot be used when the aerosol-generating material storage area 39 is empty, which could damage the aerosol generator 36 or other components of the article 30 and aerosol provision device 20.
  • the value of the counter is updated to the reset value in response to the article being filled aerosol-generating material 32. Accordingly, when a new article 30 where the value of the counter is equal to the initial value is filled aerosol-generating material 32, the value of the counter is updated to the reset value, thereby indicating that the article 30 has been filled with filled aerosolgenerating material 32 and that the aerosol generator 36 can be enabled.

In other words, unlike the value of the first counter that is updated to the reset value when the article 30 is filled aerosol-generating material 32, the value of the second counter is not changed or updated by the article control circuitry 38 when the article 30 is filled aerosolgenerating material 32. The value of the second counter is therefore independent of the number of times the article 30 has been filled/refilled with aerosolgenerating material 32.
  • the article control circuitry 38 can be configured to permanently prevent electrical power from being supplied to the aerosol generator 36 based on a comparison between the value of the second counter and a usage limit.
