Inhalation device with user recognition based on inhalation behavior

摘要

A method for controlling the operation of an inhaler including a gas flow path serving as a passage through which gas can be extracted by a user's smoke absorption operation, a gas flow sensor in the gas flow path, and a memory, the method comprising: Recording a gas flow measurement from the gas flow sensor; comparing the gas flow measurement with a user's smoke absorption characteristics stored in memory; and providing a correlation score; based on the value of the correlation score Enabling or disabling further operation of the device. This method allows an inhalation device, such as an electrically activated smoking device or medical inhaler, to authenticate the user of the device based on the detected smoke absorption behavior.
