Abstract: An electronic smoke comprises a puff detection sub-assembly module. The puff detection sub-assembly comprises a first conductive surface, a second conductive surface and an insulated ring spacer separating the first and the second conductive surfaces at an effective separation distance. The first conductive surface, the second conductive surface and the insulated ring spacer are housed inside a metallic can. The first conductive surface is electrically connected to the metal can by a first conductive ring which is disposed between the first conductive surface and a ceiling portion of the metal can. The second conductive surface is electrically connected to an output terminal through a second conductive ring, the second conductive ring elevating the puff detection sub-assembly above a floor portion of the metal can and urging the first conductive ring against a ceiling portion of the metal can.

Abstract: A non-nicotine e-vaping device includes a heater, a power control circuit, and a memory module. The heater element is configured to heat a non-nicotine pre-vapor formulation, the non-nicotine pre-vapor formulation being devoid of nicotine and including at least one non-nicotine compound. The power control circuit is coupled to the heater element through a wire. The power control circuit is configured to apply a pulse width modulated power signal to the heater element through the wire, and to receive information over the wire. The memory module is configured to detect a plurality of pulses in the pulse width modulated power signal, record information based on the detected plurality of pulses, and output the recorded information to the power control circuit via the wire.
