Abstract: Vaporizer devices are disclosed. In one exemplary embodiment, a vaporizer device can include a vaporizer body including a first airflow path extending at least partially therethrough, and a sensor assembly residing at least partially within the vaporizer body. The sensor assembly includes a flexible sensor that is in communication with the first airflow path. The flexible sensor is configured to reversibly deflect from an initial state to a first state in response to a first user-activated force representing air being drawn through the first airflow path, and configured to reversibly deflect from the initial state to a second state in response to a second user-activated force representing an acceleration of the vaporizer body. Sensor assemblies for a vaporizer device are also provided.

Various embodiments of the vaporizer cartridge are described that include one or more features for maximizing a reservoir volume within the vaporizer cartridge for the containing of vaporizable material thereby increasing the output of vaporized vaporizable material from a compact cartridge configuration. Additionally, associated methods of manufacturing are described.

Abstract: A system for aerosolization of compartmentalized materials is provided. In some implementations, the system performs operations comprising vaporizing, by a heater, at least a portion of a first material to form a first vapor, wherein the first material is stored in a reservoir coupled to the heater. The operations can further comprise providing, through a draw channel comprising the heater, the first vapor to a second material within the draw channel, wherein the second material comprises one or more of nicotine and an acid, wherein the second material is positioned between the resistive heater and an exit point of the draw channel. The operations can also include forming, based on the first vapor passing through and/or around the second material, an inhalable vapor. Related systems, methods, apparatuses, and articles of manufacture are also described.

Abstract: Vaporizer devices and methods for detecting inhalation through a vaporizer using a heating element are provided. A resistive heater of a vaporizer may function as both a heater and as an anemometer to detect inhalation. Alternatively or additionally, a separate resistive heater may be included in an air path through the vaporizer to detect a user inhaling through the vaporizer. A heating control mechanism utilizes the already existing heating element in an anemometric correlation to when the vaporizer is idle and when it is being used (where being used implies the user is taking a puff/inhalation on the vaporizer). Using this information, a controller of the vaporizer accordingly controls heating to the vaporizer as required.

Abstract: A nicotine liquid formulation comprising nicotine, an acid, and a biologically acceptable liquid carrier, wherein heating an amount of said nicotine liquid formulation using low temperature electronic vaporization device, i.e., an electronic cigarette, generates an inhalable aerosol, and wherein at least about 50% of said acid in said amount is in said aerosol, and wherein at least about 90% of said nicotine in said amount is in said aerosol.

Abstract: Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing, an airflow tube that extends through the reservoir housing, and a folded mesh that is disposed within the airflow tube and includes a plurality of folds. The airflow tube defines a passageway extending therethrough and at least a portion of the airflow tube is permeable to the vaporizable material, in which the permeable portion of the airflow tube is configured to draw vaporizable material from the reservoir housing into the airflow tube for vaporization. The folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize at least a portion of the vaporizable material drawn from the reservoir housing. Vaporizer devices are also provided.

Abstract: An electronic cigarette with an atomizer cartridge and a battery assembly. The atomizer cartridge has an atomizer coupled to a first and second terminal of a cartridge interface. A passive electrical circuit is coupled between the first terminal and a sensing terminal. The battery assembly has an interface with a first, second, and sensing contact. The interface engages the cartridge interface to provide electrical continuity between the terminals and contacts. The battery assembly has an atomizer drive circuit connected between the first and second contact, and a controller that activates the atomizer drive circuit in response to negative pressure at a draw sensor. A sensing circuit coupled to the sensing contact outputs a parameter signal indicative of the electrical parameters of the passive electrical circuit. The controller activates an RGB LED to produce discrete colors of light corresponding to discrete values of the parameter signal.
