In addition, similar protocols and methods can be used to provide benefits or sensations to the end user, for example, of active materials such as those disclosed in U.S. application No. 14/271, 071.

There is provided herein a device for generating an inhalable aerosol comprising a separable cartridge and a body, the separable cartridge having a first heating element, a second heating element, a first compartment containing a vaporisable material and a second compartment containing a vaporisable material, wherein the vaporisable material in the first compartment is the same or different to the vaporisable material in the second compartment; the body has a battery and a circuit for controlling the device, wherein the case and the body are connected by a first connecting mechanism.

The detachable cartridge includes a plurality of compartments, wherein at least one compartment has at least one heating element and at least one vaporizable material. The apparatus is configured such that each compartment housing at least one resistive heating element further comprises a wicking material in direct contact with the vaporizable material in the compartment. At least one heating element in at least one compartment is exposed to the air passage in the cartridge.

The at least one resistive heater in the cartridge is designed to reach a near controlled target temperature that is below the pyrolysis temperature of tobacco, and more specifically, a target "vapor temperature" of greater than about 100 ℃ but below about 300 ℃, with the intent of converting the vaporizable material in the at least one compartment to a visible vapor, such as about 170 ℃ for flavorants, about 190 ℃ for nicotine, and about 210 ℃ for humectants.

In some embodiments, the single button interface also provides a mechanism for selecting a particular heater activation within the cartridge. In some embodiments, (not shown) additional buttons for any of these functions are included. For example, pressing a single button for 1 second turns on the device. Holding the button for 5 seconds inhibits action-based low power standby and automatic shut-off. Optionally, a second button is used to disable the motion-based low power standby and/or off. In some embodiments, after power up, if a single button is pressed for a long time (>10 seconds), the device will turn off again. This is to prevent inadvertent activation while in a bag or the like, which would be immediately turned off by pressing a button when turned on. In some embodiments, a single or more buttons may report battery charge (by LED flashing, for example), change the operating temperature of the device or change the rated brightness of the LED if the user is in a dark environment and does not want light to be distracted. These different features are triggered using one or more buttons or using the same button by pressing it for a specified press duration or several times.

Provided herein is an apparatus for generating an inhalable aerosol comprising: a separable cartridge having a first heating element, a second heating element, a first compartment containing a vaporizable material, and a second compartment containing a vaporizable material, wherein the vaporizable material in the first compartment is the same as or different from the vaporizable material in the second compartment; and a body having a battery for controlling the device, at least one activation button, and circuitry for controlling the device, wherein the device includes a first capacitive sensor coupled to the circuitry. In some embodiments, the surface or housing of the device triggers the first capacitive sensor upon a user input to the surface or housing of the device.

In some embodiments, the circuit causes the heating element to enter a preheat state upon activation or triggering of the first capacitive sensor. In some embodiments, the device exits the preheat state or shuts down when the first capacitive sensor is no longer able to detect activity of the device. In some embodiments, the surface of the device comprises two electrically isolated capacitive sensing regions, wherein the first region comprises a first capacitive sensor and the second region comprises a second capacitive sensor. In some embodiments, the device alerts the user that the device is in use or ready when the user touches the first region. In some embodiments, the device prompts for a use or ready status by displaying a pattern of one or more LEDs, displaying a predetermined color of one or more LEDs, or providing an audible signal. In some embodiments, the zones are configured such that when a user touches one of the zones in one or more predetermined patterns of touches, the device displays the charge of the battery with a pattern of one or more LEDs or with the color of one or more LEDs, or with an audible signal. In some embodiments, the zones are configured such that when the user slides a finger from the first zone to the second zone, or slides a finger from the second zone to the first zone, the device displays the charge of the battery with a pattern of one or more LEDs or with the color of one or more LEDs, or with an audible signal. In some embodiments, the apparatus is configured to further comprise a detachable mouthpiece, wherein the mouthpiece is a detachable cartridge. In some embodiments, the nozzle has at least one air passage therethrough, and the at least one heating element is exposed to the air passage.

In some embodiments, the compartments containing vaporizable material are arranged in series within the separable nozzle cartridge, in parallel within the separable nozzle cartridge, concentrically within the separable nozzle cartridge, and/or in any combination of series stacked arrangements, concentric arrangements, and parallel arrangements within the separable nozzle cartridge. In some embodiments, the second capacitive sensor coupled to the circuit is activated by contacting the device to the user's lips, whereby the device heating element enters a pre-heat state. In some embodiments, the heating element is fully activated when the user inhales and generates an aerosol that can be delivered to the user by such inhalation or another inhalation. In some embodiments, inhalation activates the pressure switch to fully activate the heater element. In some embodiments, the device includes a button or touch sensor that, when pressed or touched, fully activates the heater element and thereby generates an aerosol that can be delivered to the user by inhalation.
