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.

Abstract: A system may include a memory that includes a database of retailer-supplied promotions associated with a first plurality of brand items, and a database of promotions associated with a second plurality of brand items. The system also includes a communications interface configured to communicate with a remote device and a processor coupled to the memory and the communication interface. The processor is configured to determine whether a given promotion matches any retailer-supplied promotion, and when the given promotion matches, then not send a corresponding digital promotion via the communications interface to the remote device. The processor is also configured to, when the given promotion does not match, then send the corresponding digital promotion via the communications interface to the remote device for redemption.
