The microprocessor is configured to measure the voltage and control operation of functional element(s) of the aerosol delivery device based thereon.

A heating preservation system includes a selected unit, a control unit, a detection unit, and a heating unit. The selected unit is configured to select a preset temperature from amongst a plurality of differing preset temperatures, each preset temperature corresponds to a preset voltage. The control unit is configured to send out the preset voltage according to the selected preset temperature. The detection unit is configured to detect a temperature of fluid and convert the temperature to a detected voltage. The comparison unit is configured to receive the preset voltage and the detected voltage and compare the detected voltage with the preset voltage. The heating unit is configured to heat the fluid when the detected voltage is less than the preset voltage, and stop heating the fluid when the detected voltage is more than the preset voltage. A smart cup using the heating preservation system is further disclosed.

An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

A method of manufacturing an atomizing unit comprises: a step A of measuring a resistance value of a resistive heating element which atomizes an aerosol source by resistance heat; and a step B of recording the resistance value measured in the step A, an adjusted power supply output determined in accordance with the resistance value as a power supply output to the resistive heating element or identification information associated with the resistance value or the adjusted power supply output in an information source.

An electronic cigarette with a memory and ability to record the amount and duration of inhalation of nicotine vapor. The electronic cigarette may be integrated with a smart phone application or other software to record usage and provide feedback to the smoker. The application may include an algorithm for the development of a withdrawal schedule for the user to quit smoking or vaping.

A flavored vapor generator (100, 200, 300, 400) used for an electronic smoking apparatus (10) comprises a housing; a liquid retention material (155, 255) which is filled, soaked or immersed with a flavored liquid and received inside the housing; an electric heater (150, 350, 450) for heating the liquid retention material (155, 255) to generate flavored vapor; and a sensor (156, 356, 456) for monitoring soaking or wetness conditions of the liquid retention material (155, 255) and providing signals for determining whether the flavored liquid in the liquid retention material (155, 255) is exhausted or almost exhausted.

An intake air heating system for a vehicle includes an electrical switching device configured to selectively connect a battery of the vehicle to a heater coil in contact with intake air of the vehicle. The intake air heating system includes a control circuit configured to, in response to an enable signal from an engine controller, drive the electrical switching device to connect the battery to the heater coil at full current. The control circuit is configured to measure a resistance of the heater coil indicative of a temperature of the heater coil.
