An air treatment system is disclosed that includes a modular configuration whereby a fan module, filter module, and humidifier module may couple together to provide a plurality of air treatment solutions. In more detail, the modules can stack end-to-end in a vertical configuration. The modules may electrically couple to each other via a common electrical bus and enable a controller disposed in the fan module (or other module) to control fan flow rates, direction, and humidity. The fan module can include an articulating nozzle capable of directing airflow in virtually any direction and angle about an environment. The fan module can further include an inlet arrangement that can selectively restrict external air from entering the fan module housing when the fan module is fluidly coupled to the filter module. Thus, the fan module may generate air flow from exclusively filtered air to minimize or otherwise reduce bacterial/mold growth within the fan module housing.

A drone which can be piloted autonomously or by a user. The drone has an air treatment dispenser for spraying, or otherwise treating, a target area with one or more desired air treatments. The drone may operate as deemed desirable by a user, upon a predetermined schedule or in response to a demand signal from one or more target areas. By delivering the air treatments from an elevated position, the target area can be more uniformly and efficiently treated.

A system for releasing edible material is disclosed. The system comprises: a plurality of compartments adapted to receive a respective plurality of capsules, each capsule containing therein an edible material; a dispenser system configured for dispensing into an environment a fluid obtained from at least one edible material; and a controller configured for receiving data pertaining to a selection of at least two of the compartments and for signaling the dispenser system to dispense fluids obtained from edible materials contained in capsules of the selected compartments.

A volatile composition dispenser and methods of detecting the replacement of a cartridge of volatile composition are provided. The cartridge of the volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. A method of volatilizing the volatile composition includes operating the evaporative assistance elements with varying energy over a total emission program. Replacement of the cartridge by a user when the volatile composition dispenser is disconnected from an external power source is detected in order to reset the total emission program when reconnected to the external power source.

A scent delivery system includes scent delivery units that are configured to deliver scent at a variable scent level by being turned on and off successively according to a variable duty cycle. The scent delivery units are associated with corresponding base scent settings. The scent delivery system also includes a central controller configured to control the scent delivery units by generating command data based on a scenting schedule that indicates a desired activation time for more than one implicated scent delivery unit. The scenting schedule is configured to further indicate a scent level bias to be applied to the base scent settings that are associated with different of the implicated scent delivery units. The central controller is configured to generate the command data, based upon a variation in the scent level bias, that takes into account a corresponding variation to duty cycles that are associated with different of the implicated scent delivery units and to communicate the command data to the different implicated scent delivery units.

A scent delivery system includes first and second scent delivery units and a central controller. The central controller is configured to generate command data capable of affecting operation of at least the first and second units based on one or more scenting schedules. The central controller is also configured to determine a relatedness and an order of priority between the units, and determine whether a desired activation time for the first unit overlaps at least partially with a desired activation time for the second unit. Based upon a determination that the first unit is related to the second unit and that a desired activation time for the first unit overlaps at least partially with a desired activation time for the second unit, the central controller is further configured to coordinate activity level of each of the first and second delivery units during the overlapping activation time according to the order of priority.

An aerosol generator includes a composite conduit to transport multiple liquids to a heating element at flow rates such that the liquids arrive at the heating element in desirable concentrations. The heating element volatilizes the liquids to form volatilized fluid, which mixes with ambient air to form an aerosol with desirable concentrations of the multiple liquids.

Disclosed is an air purification system (10) comprising an air purifier apparatus (50) for removing a pollutant from air, a sensor (21, 23) for sensing a concentration of the air pollutant and a scent release apparatus (40) responsive to a scent release signal, wherein the air purification system further comprises a processor (31) adapted to monitor the pollutant concentration from sensor data received from the sensor and to generate the scent release signal upon the monitored pollutant concentration falling below a defined threshold. Also disclosed is a method of generating a scented atmosphere in a room housing an air purification apparatus (50) for removing a pollutant from the air in the room.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

A fragrance dispenser and a corresponding method of dispensing fragrance, comprising at least one receptacle having a major open end, with a porous diffuser layer occlusively overlying the major open end of the receptacle, wherein at least a sectional area of the porous diffuser layer is removable to uncover a portion of the receptacle to control of the release rate of a fragrance source. The fragrance dispenser may comprise a plurality of receptacles and the porous diffuser layer comprises a plurality of sections that are individually removable to uncover each receptacle. The fragrance dispenser could comprise a removable cover sheet that is peelably detachable from the porous diffuser layer. Porous diffuser layer could be an organic polymeric nonwoven web and/or the receptacle is made of a thermoplastic organic polymeric resin. The fragrance dispenser may further comprise a secondary diffuser layer that has 50% more permeability that the porous diffuser layer.
