A control body and cartridge are coupleable to form an aerosol delivery device, the control body comprising a control component coupled to an RFID reader, and the cartridge comprising an aerosol precursor composition and RFID tag. The RFID reader communicates with the RFID tag upon coupling of the control body with the cartridge. The control component authorizes the cartridge for use with the control body based at least in part on communication between the RFID reader and RFID tag. The RFID reader including a reader antenna located proximate a tag antenna of the RFID tag upon coupling of the control body and cartridge. The communication between the RFID reader and RFID tag includes communication between the antennas, the reader antenna being at most two millimeters in length to render the RFID reader incapable of communication with any device external to the control body other than the RFID tag.

An electronic droplet delivery device with an inhalation mouthpiece that includes multiple fluid reservoirs and multiple aperture plates. Multiple fluid reservoirs allow for different fluids, such as medicines, nicotine, chemicals for marijuana, and flavorings to be separately provided from separate reservoirs into a resulting combined droplet stream inhaled by a user through the mouthpiece.

An electronically actuated droplet delivery device with a housing including a mouthpiece, a fluid reservoir; an electronically actuated aperture plate comprised of high modulus polymeric material and having a plurality of openings formed through its thickness configured to generate an ejected stream of droplets, and an electronic actuator operably coupled to oscillate the aperture plate at a frequency that generates the ejected stream of droplets.

An electronic droplet delivery device includes a housing including a mouthpiece located at an airflow exit side of the housing, a fluid reservoir, an aperture plate having a plurality of openings that receives fluid from the reservoir, an electronic actuator that oscillates the aperture plate to generate an ejected stream of droplets, and an ejector closure that opens and closes to help seal and prevent evaporation from the aperture plate when the droplet delivery device is not being used.

An electronically actuated droplet delivery device with a mouthpiece for inhaling fluid droplets includes an aperture plate with a plurality of openings. The plurality of openings includes multiple sizes to produce different sizes for targeting different locations of a user's inhalation system, such as mouth locations, throat locations, and lung locations.

An electronic droplet delivery device having a mouthpiece of inhalation of droplets includes an aperture plate with a plurality of openings coupled to a piezoelectric actuator. A fluid reservoir supplies a solution with nicotine to the aperture plate for ejection out of the mouthpiece in a droplets stream.

An electronic droplet delivery device includes a housing including a mouthpiece located at an airflow exit side of the housing, a removable fluid reservoir, an aperture plate having a plurality of openings that receives fluid from the reservoir, an electronic actuator that oscillates the aperture plate to generate an ejected stream of droplets, and a sensor operably coupled to trigger the actuator to generate the ejected stream of droplets when a predetermined inhalation flow rate is detected by the sensor.

A medical treatment system is configured to output a predefined test pattern and to receive the signal by way of a microphone in order to test the volume and quality of the audio output in order to ensure the output audio signals effective to wake a sleeping patient. The failure of a processor to confirm the volume and fidelity of the audio output as well as the timeliness of the test pattern causes the processor to deny the resumption of a treatment and to generate an error signal.

A method of providing a vaping policy alert by a mobile communications device comprises receiving, at the mobile communications device, mobile network data from a base station; extracting a country code for the location of the mobile communications device from the received mobile network data; obtaining vaping policy alert data responsive to the obtained country code; and displaying the vaping policy alert data.

An electronic droplet delivery device includes a housing including a mouthpiece located at an airflow exit side of the housing, a removable fluid reservoir, an aperture plate having a plurality of openings that receives fluid from the reservoir, an electronic actuator that oscillates the aperture plate to generate an ejected stream of droplets, and an electronic chip coupled to the fluid reservoir that communicates information applicable to use of the droplet delivery device with the fluid reservoir.
