An apparatus includes a housing including a power source; a reservoir including an inlet, an outlet, and configured to contain vaporizable material and couple to the housing; and a PTCR heating element configured to electrically couple to the power source and heat the vaporizable material to form an aerosol. The PTCR heating element includes an electrical resistivity that varies based on temperature. The electrical resistivity includes an electrical resistivity transition zone including an increase in electrical resistivity over a temperature range such that, when the PTCR heating element is heated to a first temperature within the transition zone, current flow from the power source is reduced to a level that limits further temperature increases of the PTCR heating element. Related apparatus, systems, techniques, and articles are also described.

The invention relates to an inhaler, in particular an electronic cigarette product, comprising at least one evaporator unit with at least one electric evaporator for evaporating liquid supplied to the evaporator and comprising an electronic controller for controlling and/or regulating the at least one evaporator unit. The inhaler has at least one replaceable cartridge, wherein the cartridge has the evaporator unit and a liquid tank which is connected or can be connected to the evaporator unit.

A mist inhaler device (200) for generating a mist for inhalation by a user. The device includes a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

A vaporization device includes biometric recognition systems. A vaporizer device is provided. The vaporizer device includes a vaporizer body comprising a cartridge receptacle, a heating element, a power source, and a sensor. The vaporizer device further includes a vaporizer cartridge that is selectively coupled to the vaporizer body, the vaporizer cartridge comprising one or more translucent surfaces and a passageway between the sensor and the one or more translucent surfaces. The vaporizer device further includes a controller configured to determine, based on data from the sensor, whether a user is authorized to use the vaporizer device. The controller further configured to provide power to the heating element to generate an aerosol responsive to determining the authorization of the user. Related methods and articles of manufacture are also described.

There is described a dry powder medicament delivery device comprising: a medicament container containing a unit dose of dry powder medicament; a medicament dispensing assembly; and optionally an air source.

A fluid vaporization device and related method of vaporization are disclosed. A vaporizable fluid is transported from a fluid reservoir to a vaporization chamber via a wick element which extends into both the fluid reservoir and the vaporization chamber. The fluid in the vaporization chamber is then heated by activating a heating element which is disposed, at least partially, within the vaporization chamber. The heating step transforms the fluid stored in the wick element into a vapor, after which it is transported out of the vaporization device via a conduit.

A fluid dispenser comprising a body (1), a fluid reservoir (2), a dispenser member, such as a pump or a valve, mounted on said reservoir (2), and a dose indicator device for indicating the number of doses of fluid that have been dispensed or that remain to be dispensed from said reservoir, the dispenser being characterized in that said dose indicator device includes a first safety system for actuating the dose indicator device once the dispenser has performed a predetermined incomplete actuation stroke, even if the dispenser does not perform the complete actuation stroke.

There is provided in accordance with an exemplary embodiment of the invention, a device and a method for controlled extraction of at least one active substance from at least one type of plant matter by application of heat, the device comprising: a heating element adapted to apply heat to an area of the plant matter to extract the substance; and a mechanism adapted for moving the plant matter relative to the heating element. Optionally, the active substance is a restricted substance. There is also provided in accordance with an exemplary embodiment of the invention, a method of monitoring and controlling inhalation of a restricted substance. There is provided in accordance with an exemplary embodiment of the invention, a method of manufacturing a tape of plant matter comprising an active substance.

Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.

The method includes defining a cavity within a housing of a vapor-generating article, the vapor-generating article having a first end, a second end and a middle section, first inserting at least one portion of a retention medium within the housing between the first end and the middle section, and second inserting a first frangible capsule to be near or at least partially within the retention medium, the first frangible capsule including a first volatile substrate.
