An exemplary smoking topography circuit of an electronic aerosol smoking article, includes at least one sensor configured to measure user interaction with the smoking article, a processor, and memory. The processor is configured to detect a smoking event based an output of the at least one sensor, collect data associated with the smoking event, and arrange the data in a pattern that associates the smoking event to shifts in battery voltage. The memory is configured to store the data pattern in a structured multi-byte format.

An apparatus for testing vaporizers of electronic cigarettes is disclosed. Each vaporizer comprises a heating element, and electric terminals for electrically powering the heating element. The testing apparatus comprises a holding construction part with multiple movable vaporizer holding units. A contact construction part is provided with multiple electric contact members each associated with a respective holding unit, and electrically contacting at least one electric terminal of a vaporizer in the associated holding unit. A supply construction part conducts electric power to each contact member. A measuring part measures at least one electric quantity representative of an electric resistance and/or inductance of the heating element, compares the measured quantity with a pre determined range and, if the measured quantity is outside the range, outputs a rejection signal.

A heater for a vaporizer with air preheating element includes a casing, a tunnel with a perforated bottom, which is a cylindrical heating chamber for placing a cigarette, a heating element of a resistive type, a heat exchanger, including air channels for circulation and preheating of air by a heater, a top end and a bottom end, an air intake hole made in the top end. Outlet holes are communicated with exits of air channels of the heat exchanger for intake of air preheated by the heater in the tunnel. The casing is made in the form of a tape of a thin-film dielectric heat-resistant material, on which a thin layer of resistive material with contacts is applied on the end of one side, forming the heating element, and on the other side a top and bottom spacers are fixed and inclined toward the middle, as well as the edging, which are made of flexible heat-resistant material. The above mentioned tape with a heating element, located on its external side, is rolled into a cylinder and forms a tunnel, and is additionally coiled into several interconnected spiral coils, and forms a spiral casing with the top and bottom ends so that the top and bottom spacers and the edging located on the inside form a spiral heat exchanger comprising the top and bottom and the middle spiral air ducts for spiral and labyrinth circulation and preheating of air, and at the bottom there is an additional inlet hole for air intake.

Provided herein are systems and methods for testing a heat-not-burn tobacco product. A heater carrier may be movable with respect to a tobacco product placement region and configured to heat a first end of a tobacco product located in the tobacco product placement region. A puffing simulator is configured to fluidically couple to a second end of the tobacco product. The puffing simulator is configured to draw air through the tobacco product thereby simulating a puff of the tobacco product. A thermocouple placement right is configured to selectively position one or more thermocouples in or along the tobacco product. A drill is configured to selectively drill one or more holes at positions within the tobacco product. The thermocouple(s) are positioned on or within the tobacco product and generate data corresponding to detected temperatures of the tobacco product as the puffing simulator simulates one or more puffs.
