A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control to control the heating element to activate and vaporize components of the aerosol precursor composition. The proximity sensor detects a presence of an object nearby the control body without requiring any physical contact with the object. And the proximity sensor or control component controls operation of at least one functional element of the aerosol delivery device in response to the presence of the object so detected. In another aspect, a cartridge may include a proximity sensor to detect a level of the aerosol precursor composition, and operation of functional element(s) may be controlled in response to the level of the aerosol precursor composition so detected.

A system to provide media (e.g., scent, therapeutics, other substances) includes a dispenser that may include a reservoir, an actuator (e.g., nebulizer), and an outlet through which a vapor or aerosol may be supplied or dispensed, the vapor or aerosol, for example comprising readily-soluble droplets having a median size range of approximately 2 microns to approximately 50, 20, or 10 microns for introduction to vessel. An interface is positionable over an opening of the vessel to close the opening while allow media to be dispensed into the interior of the vessel, thereby retaining the dispensed media until taken in by a user. The interface (e.g., annular plate) has a pair of opposed major surfaces, and the first major face supported on a rim of the vessel, with the dispenser supported on the second major face in an inverted orientation. A sensor may sense orientation, and cause an actuator (e.g., nebulizer) to dispense media when in the inverted orientation or otherwise titled for normal.

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.

A system may include a mobile application residing on an external device and an inhalation device. The inhalation device may include a mouthpiece, a mouthpiece cover, medicament, and an electronics module comprising a processor. The inhalation device may be configured to both prepare a dose of medicament for delivery to a user and cause the processor to transition between power states when the mouthpiece cover is moved from a closed position to an open position to expose the mouthpiece. The electronics module or the mobile application may be configured to generate usage events based on usage of the inhalation device by the user. The electronics module may also include a pressure sensor, and the electronics module or the mobile application may be configured to determine whether a usage event is a good inhalation event, a fair inhalation event, or a no inhalation event based on feedback from the pressure sensor.

An apparatus including a first cartridge, a sensor, and a controller. The first cartridge can include a first release device configured to release a first substance into a housing. The controller can be configured to receive data from the sensor. The controller can determine an amount of first substance released by the first cartridge based on the data. The first release device can be controlled based on the determined amount of first substance.
