Abstract: A system comprising an aerosol provision system and a computer. The aerosol provision system is configured to generate aerosol from an aerosol-generating material. The computer is configured to obtain user behaviour data relating to an amount of an ingredient delivered from the aerosol-generating material to a user of the aerosol provision system. The computer then determines default user behaviour with respect to the amount of the ingredient to be delivered on the basis of the obtained user behaviour data. The computer then monitors a current interaction by the user with the aerosol provision system, and when the current user interaction deviates from the default user behaviour with respect to the amount of the ingredient delivered by a pre-determined amount, the computer provides a notification to the user.

Abstract: A combined toroid/shunt device for detecting residual current in an electrical installation comprising a plurality of conductors such as a live conductor (2) and a neutral conductor (3) is described. The device comprises a toroid means (1, 4) for detecting an AC residual current within a first range and a plurality of resistive shunts (6a) to (6d) for connection in respective ones of the plurality of conductors. A current detection means (5, 7, 13) responsive to current flowing in each of said shunts for detecting a DC residual current and/or an AC residual current within a second range is described. The first range of AC residual current is an AC residual current resulting from earth leakage or cross-leakage between conductors up to a saturation level at which the toroid or electronic means associated means therewith becomes saturated. The second range includes an AC residual current of said saturation level.
