A system and method for producing a fragrance. The system may include body having a plurality of chambers defined therein. Each chamber may include a fragrance accord. A circuit and a plurality of emitters may be positioned within the body. The emitters may be connected to and controlled by the circuit, and each of the emitters may be positioned adjacent to a corresponding one of the chambers and control ejection of the fragrance accord therein.

The aspects presented herein provide fragrance compositions having an olfacive profile that changes with time, wherein the fragrance compositions comprise at least two contrasting perfume accords that provide an olfactory modulating effect, wherein the perfume formulation delivers a desirable scent with increased perceived intensity and improved longevity of perception.

An electrical heating evaporator for evaporating active substances such as perfumes and/or insecticides, in which the evaporation rate regulator includes an electrical heater resistor for which the power supplied is regulated through a potentiometer constructed on a printed circuit board. The evaporation rate can be adjusted for a wide variety of types of chemical substances, without the need of substantially modifying the design of the device.

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 dispensing device comprising a body with an attachment mechanism configured to connect to a subject, a reservoir disposed inside the body, a removable selected fragrance disposed inside the reservoir, a dispenser coupled to the reservoir, a controller coupled to the dispenser and configured to dispense the selected fragrance, and a plurality of sensors on the body configured to provide data streams to a smart device.

An apparatus is provided including a base, a main trunk body coupled to the base, and a plurality of branches coupled to the main trunk body. The apparatus includes a plurality of scent component devices coupled to the main trunk body or the plurality of branches, where the plurality of scent component devices are disposed in receiving portions of the main trunk body or the plurality of branches. Further, each scent component device may be inserted into the receiving portions of the main trunk body or the branches, where the scent component device is configured to receive one or more scent modules including a scent material. When the scent component device is activated, the scent component device releases or diffuses a distinct scent using the scent material into an area that the apparatus is disposed.

An apparatus and method for reducing scent emanating from a substantially enclosed structure such as a hunting blind. A fan in a fluid conduit draws odor-laden air from the internal environment and passes it through an ozone-rich vicinity provided for example by one or more ozone generators, then exhausts the treated deodorized air to the external environment. Fresh air is introduced into the negative-pressure enclosure from the external environment through one or more gaps or cervices in the structure.

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.

A method for controlling one or more scent delivery units includes maintaining one or more scheduled events, maintaining one or more scheduled anti-events, and generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control their activation and deactivation. Generating the command data includes identifying a conflicting period of time during which control specified by the one or more scheduled events differs from control specified by the one or more scheduled anti-events and also includes generating command data that gives priority to control specified by the one or more scheduled anti-events. Control for the one or more scent delivery units during the conflicting period of time is in accordance with control logic of the one or more scheduled anti-events and not the one or more scheduled events.

Provided is a fragrance presentation device (100) that presents a fragrance in conjunction with content including at least one element of a sound, a music, an image, a video, and a tactile stimulation. The fragrance presentation device includes a housing unit (104) that houses a cartridge containing one or a plurality of aromas, and a discharge unit (106) that discharges the aroma. The fragrance presentation device (100) discharges the aroma in synchronization with an output of the content according to the aroma score including at least one element of an aroma type, an aroma generation timing, a discharge duration, a discharge amount, a discharge pattern, and a discharge trigger.
