Abstract: At least one example embodiment provides a system for controlling a heater in a non-combustible aerosol-generating device, the system comprising a memory storing computer-readable instructions and a controller configured to execute the computer-readable instructions to cause the non-combustible aerosol-generating device to apply a first power to the heater based on a first preheat temperature determine an estimated energy applied to the heater during application of the first power, and apply a second power to the heater based on the estimated energy, an energy threshold and a second preheat temperature, the second power being less than the first power.

Abstract: The heating engine control circuit includes a rail converter circuit and a gate driver circuit. The rail converter circuit is configured to convert a power supply voltage into a power signal based on a vaping enable signal, the vaping enable signal being a pulse width modulated signal. The gate driver circuit includes an integrated gate driver. The integrated gate driver is configured to control application of power to a heater of the non-nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

Abstract: A device assembly includes a controller, which is configured to control the non-nicotine electronic vaping device to output an indication of a current level of the non-nicotine pre-vapor formulation in the non-nicotine reservoir of a non-nicotine pod assembly in response to determining that an aggregate amount of non-nicotine pre-vapor formulation drawn from the non-nicotine reservoir or an aggregate amount of vaporized non-nicotine pre-vapor formulation is greater than or equal to the at least one non-nicotine pre-vapor formulation level threshold.

Abstract: The non-nicotine electronic vaping device includes processing circuitry configured to: determine a plurality of resistance values for a heater during a time window; calculate a percent change in resistance of the heater between a first of the plurality of resistance values and a second of the plurality of resistance values; decide whether the percent change in resistance of the heater exceeds a percent change in resistance threshold; and disable power to the heater in response to deciding that the percent change in resistance of the heater exceeds the percent change in resistance threshold.

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.

Abstract: An e-vapor apparatus may include a pod assembly and a dispensing body configured to receive the pod assembly. A vaporizer may be disposed in the pod assembly and/or the dispensing body. The pod assembly may include a vapor precursor compartment, a device compartment, and a vapor channel extending from the device compartment and traversing the vapor precursor compartment. The pod assembly is a smart pod configured to receive, store, and transmit information that can be communicated with the dispensing body and/or another electronic device. The proximal portion of the dispensing body includes a vapor passage and a through-hole. The vapor passage may extend from an end surface of the proximal portion to a side wall of the through-hole. The through-hole is configured to receive the pod assembly such that the vapor channel of the pod assembly is aligned with the vapor passage of the dispensing body.

Abstract: A non-nicotine e-vaping device may include a non-nicotine pod assembly and a device body. The non-nicotine pod assembly has upstream and downstream ends and is configured to hold a non-nicotine pre-vapor formulation. The upstream end may define at least one upstream recess, and the downstream end may define at least one downstream recess. The device body defines a through hole configured to receive the non-nicotine pod assembly. The through hole includes an upstream sidewall and a downstream sidewall. The upstream sidewall may include at least one upstream protrusion, and the downstream sidewall may include at least one downstream protrusion. The at least one upstream protrusion and the at least one downstream protrusion may be configured to engage with the at least one upstream recess and the at least one downstream recess, respectively, so as to retain the non-nicotine pod assembly within the through hole of the device body.
