    • An aerosol provision system, such as an electronic cigarette, comprises a heating element for generating an aerosol from a source liquid and control circuitry for controlling a supply of electrical power from a power supply, such as battery / cell, to the heating element. The control circuitry is configured to measure an indication of a derivative of an electrical characteristic of the heating element with respect to time, for example a first time derivative or a second time derivative of a resistance of the heating element (or a related parameter, such as conductance, current draw, power draw or voltage drop). Based on the measured time derivative, the control circuitry is configured to determine whether or not a fault condition, e.g. localised heating of the heating element, has arisen for the electronic aerosol provision system. The overall change in the electrical characteristic for the heating element caused by the localised heating may be small and so difficult to reliably identify, but the rate at which the change occurs can be expected to be relatively high, which can mean the time derivative of the local characteristic is more reliable indicator of the occurrence of the fault condition.
    • 诸如电子烟的气溶胶提供系统包括用于从源液体产生气溶胶的加热元件和用于控制从电源(例如电池/电池)到加热元件的电力供应的控制电路。 控制电路被配置成测量相对于时间的加热元件的电特性的导数的指示,例如加热元件的电阻的第一时间导数或第二时间导数(或相关参数,例如 作为电导,电流消耗,功率消耗或电压降)。 基于所测量的时间导数,控制电路被配置为确定故障状况,例如, 电子气溶胶提供系统产生了加热元件的局部加热。 局部加热引起的加热元件的电特性的总体变化可能很小,难以可靠地识别,但是可以预期发生变化的速率相对较高,这意味着时间导数 局部特征是故障状况发生的可靠指标。
