  • Patent number: 11413410
    Abstract: An aerosol provision system 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 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. Based on the measured time derivative, the control circuitry is configured to determine whether or not a fault condition has arisen for the electronic aerosol provision system. The overall change in the electrical characteristic for the heating element caused by the localized 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, such that the time derivative of the local characteristic is a more reliable indicator of occurrence of the fault condition.

  • Patent number: 11291251
    Abstract: An electronic cigarette includes a microprocessor, a battery module and a heating element. The battery module is electrically connected to the heating element and supplies power to the heating element with a first output parameter. The electronic cigarette further includes a sensing module, connected to the microprocessor and disposed in a smoke outlet passage of the electronic cigarette, for detecting the concentration of an analyte and sending it to the microprocessor. The microprocessor stores a preset threshold, the microprocessor receives the concentration of the analyte detected by the sensing module, and further determines the relationship between the concentration of the analyte and the preset threshold. When the concentration of the analyte is higher than or equal to the preset threshold, the microprocessor controls the battery module to supply power to the heating element with a second output parameter, wherein the second output parameter is smaller than the first output parameter.
