An aerosol delivery device is provided that includes a power source, a heating element, a switch coupled to and between the power source and the heating element, and processing circuitry coupled to the switch. The processing circuitry outputs a PWM signal during a heating time period to cause the switch to switchably connect and disconnect the output voltage to the heating element to power the heating element. The processing circuitry outputs a pulse of known current to the heating element, and measure voltage across the heating element, between adjacent pulses of the PWM signal. And the processing circuitry calculates the resistance of the heating element based on the known current and the voltage, calculates the temperature of the heating element based on the resistance, and adjusts a duty cycle of the PWM signal when the temperature deviates from a predetermined target.

The tip end is closed and the mouth-end has an opening therein. The heater support supports the planar heater. The tank contains a pre-vapor formulation and is configured to slide into and out of the opening of the mouth-end of the housing. The wick extends from the tank and is configured to be in contact with the planar heater when the tank is inserted in the housing.

Methods and systems for the production and delivery of lithium metal of high purity are provided herein. In one or more embodiments, a liquid lithium delivery system contains a liquid lithium delivery module fluidly coupled to a lithium refill container. The liquid lithium delivery module contains a lithium storage region operable to store liquid lithium and containing a fluid supply line fluidly coupling an outlet port of a liquid lithium storage tank, and a flow meter positioned downstream from the lithium storage region along the fluid supply line and operable to monitor the flow of the liquid lithium through the fluid supply line.

A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.

The present technology is directed to multi-frequency controllers for inductive heating and associated systems and methods. The systems can be configured to precisely heat a module via a coil to a target temperature using oscillating, pulsed electrical signals associated with unique frequencies and/or capacitance values. Each unique frequency can correspond to heating the module to a particular depth, relative to an outer surface of the module. A first pulsed electrical signal having a first frequency can heat the module to a first depth, and a second pulsed electrical signal having a second frequency can heat the module to a second depth different than the first depth. The system can include a thermal sensor for measuring a temperature associated with at least one of the module or a fluid associated with the module. Based on the temperature, the system can adjust signal delivery parameters of the first and/or second electrical signals.

An oxalic acid vaporizer has a modular configuration, having a dispensing module and a manually detachable heating module. This modular configuration allows the first heating module to be easily separated from the dispensing module and a substitute heating module attached to the dispensing module, thereby allowing for a very fast replacement of the heating module in the event there is a failure or overheating in the first heating module. The substitute heating module may be a duplicate of the first heating module or the substitute heating module may have a more powerful fan, be capable of greater heat, or it may be of the type having a proportional-integral-derivative controller for controlling temperature. The modular configuration provides for a continuous oxalic acid gas treatment of bee hives by allowing an operator to change out heating modules in a matter of seconds.
