摘要： A response procedure for an aerosol-generating device includes detecting a fall or shock using at least one acceleration value and initiating at least one response procedure using a controller. Acceleration values are provided by at least one accelerometer coupled to the aerosol-generating device. The response procedures may include at least one of: initiating a mechanical change in the aerosol-generating device, initiating a modification to an external device interface, generating a human-perceptible beacon, storing data associated with the fall or shock in persistent or non-volatile memory, initiating a diagnostic routine, monitoring for a lost device condition, and initiating a soft shutdown or restart.

摘要： An electrically operated aerosol-generating system is provided, including: a heating element to heat an aerosol-forming substrate proximate to the heating element; a power supply to supply power to the heating element; and electric circuitry in communication with the heating element and the power supply, the electric circuitry including a memory and being configured to: regulate a supply of power to the heating element for a heating cycle period in response to a user input, determine a first derivative of an electrical resistance of the heating element with respect to time, determine that there is an adverse condition if the first derivative exceeds a threshold value stored in the memory during a heating cycle period at or subsequent to a predetermined time in the period, and control power supplied to the heating element or provide an indication based on whether there is an adverse condition at the heating element.

摘要： An electrically operated aerosol-generating system is provided, including: a heating element to heat an aerosol-forming substrate; a power supply; a temperature sensor; electric circuitry in communication with the element, the sensor, and the power supply, and configured to regulate a supply of power based on a measured temperature, determine an adverse condition when a reduction in power required to reach or to maintain a predetermined temperature over successive heating cycles falls outside a predefined range, by comparing the power supplied in a given heating cycle with that of preceding heating cycles, the predefined range stored in the memory, and control the power supplied based on whether there is the adverse condition or provide an indication when there is the adverse condition; and a device and a removable cartridge including a liquid aerosol-forming substrate, the power supply and the circuitry being in the device and the element being in the cartridge.

摘要： An electrically operated aerosol-generating system is provided, including: a heating element configured to heat an aerosol-forming substrate proximate to the heating element; a power supply; and electric circuitry in communication with the element and the power supply, and configured to regulate the supply of power during a plurality of discrete heating cycles in response to user inputs, determine a maximum electrical resistance of the heating element during each heating cycle, calculate a rolling average value of the resistance for n preceding heating cycles, n being an integer greater than 1, compare the resistance with the calculated value, determine an adverse condition when the resistance is greater than the calculated value by more than a threshold value, the threshold value being stored in the memory, and control the power supplied based on whether there is the adverse condition or to provide an indication based on whether there is the adverse condition.

摘要： A method of controlling aerosol production in an aerosol-generating system is provided, the system including an aerosol-generating element and a housing having an air inlet and an air outlet, a flow channel defined from the air inlet to the air outlet configured to provide a flow of air past the aerosol-generating element, and a flow sensor configured to detect an air flow in the flow channel; and the method including increasing a power supplied to the aerosol-generating element for at least a second time if the flow sensor detects that the flow rate of the air flow increases past a threshold. There is also provided an aerosol-generating system comprising circuitry configured to perform the method.
