Abstract
An electronic device includes a hand held base assembly that includes circuitry including memory and firmware executed by a processor or microcontroller of the circuitry; and a cartridge assembly that includes memory that is read by the firmware of the handheld base assembly. The cartridge assembly and the handheld base assembly are configured to removably couple together to define the electronic device for producing an aerosol for inhalation by a person. An enclosed air passageway is defined by the cartridge assembly and by the handheld base assembly, which isolates the airflow from the electronics of the device. The enclosed air passageway extends between the opening of the mouthpiece for taking a breath and a diaphragm of the handheld base assembly, movement of the diaphragm changing the air pressure within an enclosed interior space having a pressure sensor for trigging the pressure sensor when a breath is taken.
