Abstract: Radically improved modular devices, system and methods make it more convenient for a user to exchange the flavoring or physiological active species with ease and without mixing of previously loaded mixtures. Likewise devices, systems, and methods for introducing flavoring, nicotine, or other chemical species desired for consumption by the user into e-cigarette vapor without heating them, thus avoiding excessive pyrolysis or degradation to those ingredients is taught. Safer alternatives to current e-liquid containers and devices, making them less accessible to children, and making harmful exposure to liquid nicotine less likely in general are shown.

Abstract: Enhanced metering systems for managing dosing aliquots feature cartridge housings for exchangeable cartridge with plugs for housing functional substances, extruding conduit tips with fluid flow conduits driven by advancing members for driving amounts of metered functional substance throughout the tips. Manual, pneumatic electrical and/or electronic means for advancing, combined with one way valves, viewing slots, multiple metering and dispensing ports enable two cartridge to be metered at once, as shown by graduated scales.

Abstract: Radically improved devices, systems, and methods make it convenient to exchange flavoring or active species with ease and without mixing of previously loaded mixtures. Devices, systems, and methods for introducing any species desired for consumption into e-cigarette vapors without heating them, thus avoiding excessive pyrolysis or degradation to those ingredients. Safer alternatives to current (pods) e-liquid containers and devices, making them NON-accessible to children, and making risk of harmful exposure to liquid nicotine eliminated mitigated or extenuated, are offered along with modular disposable components, to create a new state of the art.

Abstract: The present invention provides improved apparatus, systems, and methods of delivering a breathable fluid stream carrying an atomized or vaporized functional liquid. In particular, a fluid-permeable exchangeable cartridge is provided for containing the functional liquid to be introduced into a fluid stream comprising a breathable base fluid flowing through the cartridge. Preferably, the breathable base fluid includes a solvation enhancer such as atomized or vaporized propylene glycol or glycerin. In another aspect, a throttling valve system is provided for adjusting the ratio of flow from a breathable base fluid source through the cartridge or around the cartridge via a bypass channel, to vary the concentration of the functional liquid component mixed with the breathable base fluid.

Abstract: The present invention provides improved devices, components, and conduit assemblies for delivery of a breathable/inhalable fluid stream containing a solvation-enhancing atomized liquid, the fluid stream carrying a functional liquid component. In one aspect, devices of the invention incorporate an exchangeable fluid-permeable body, such as a cartridge comprising a fluid-permeable packing material, containing the functional liquid. In another aspect, devices of the invention incorporate an electronic control system configured to detect and store physical states, settings, modes/configurations, and/or usage of the device over time. Optionally, the detected states may be exported to a separate electronic device via a Wi-Fi or other suitable remote connection. In other embodiments, the electronic control system provides passcode authorization for actuating an atomizing element and/or toggling the device between locked and unlocked states.
