Abstract: Provided are a system and method of reproducing individual puffs based on empirical data collected by a plurality of electronic vaping devices during use of the vaping devices by users to inhale vapors. The method involves receiving, over a communication network for each of the plurality of electronic vaping devices: (i) reservoir information indicative of a configuration of a reservoir storing a liquid that is at least partially converted into the vapor, and (ii) a plurality of operational parameters for each of a plurality of puffs drawn by the users. The operational parameters include a first operational parameter measured by a sensor system provided to the respective electronic vaping device. An evaluation vaping device is controlled to reproduce a puff by generating a vapor based on the received reservoir information and the received plurality of operational parameters in effect during the puff that is being reproduced.

Abstract: Provided is an electronic vaping device that includes a heating element configured to convert a portion of a liquid into a vapor by elevating a temperature of the liquid. An airflow passage is defined by the vaping device to channel a stream of a fluid including air, or a combination of air and vapor, adjacent to the heating element as a result of a user inhaling through a mouthpiece. The stream of fluid flowing through the airflow passage entrains the vapor and transports the vapor toward the mouthpiece. A pre-heater is arranged upstream of the heating element to pre-heat at least a portion of the fluid to a pre-heated temperature. The pre-heated temperature is greater than an ambient temperature of the air that is introduced to the pre-heater. A controller independently controls the heating element and the pre-heater.

Abstract: An electronic vaporizer with heating element electrical resistance recording and replay functionality, where the device makes a real-time recording of the electrical resistance of the heating element during operation, and the user is able to select a desirable puff from those recorded for replay. On subsequent puffs, the device control system modifies power delivery to achieve a similar profile of electrical resistance over time. Additionally, an electronic circuit implementing the same functionality.
