All of these components can be mounted on the PCB 149.

[0044] The cup body 103 can protect the cartridge holder 141 which has slots 105 for the fragrance cartridges 111. The cartridge holder cover 153 has holes that match the shapes of the slots 105 in the cartridge holder 141. The fragrance cartridges 111 have vales that will normally be closed to prevent the contained fragrances from escaping until the valves are opened individually by the system to allow the fragrances to flow from the cartridges 111.

[0045] When a mobile digital aroma apparatus is first used, the cup cover lid 107 is removed and a plurality of fragrance cartridges 111 are inserted into the slots 105. The cup cover lid 107 is attached to the cup body 103 to cover the fragrance cartridge holder slots 105 and hold the fragrance cartridges 111 within the body 103. The mobile digital aroma apparatus 111 can be turned on to operate the device through a switch on the body or electronically through a wireless RF or optical signal. The mobile digital aroma apparatus 101 can illuminate an LED (or display) and be paired with a mobile phone or another computing devices so the mobile digital aroma apparatus 101 can communicate with a system server and be controlled by a mobile computing device or a computing system within a vehicle. The mobile digital aroma apparatus 101 can transmit identification information for the fragrance cartridges 111 so that the user can select a desired fragrance through a user interface (UI) and the mobile digital aroma apparatus 101 can receive control signals for emitting the desired fragrance.

[0046] Each of the fragrance cartridges 11 lean be manually inserted and removed from the cartridge holder 141. In an embodiment, the mobile digital aroma apparatus 101 can automatically partially eject a fragrance cartridge when the system detects that it has been depleted or based upon an electronic input requesting that a fragrance cartridge be removed. While the cartridge holder 141 in the mobile digital aroma apparatus 101 is illustrated as having four cartridge slots in other embodiments, the cartridge holder can have any number of cartridge slots arranged in a parallel circular manner.

[0047] FIGS. 3-5 illustrate another embodiment of a diffuser assembly that can be integrated into a climate control system of a vehicle or other structure. In this embodiment, the diffuser assembly has 4 slots for 4 fragrance and/or anti-viral sterilization cartridges 111 that are arranged in a linear manner. The diffuser assembly 201 can be enclosed within a housing that is made from the assembled cartridge holder 214, a cover 202, a cover insert 203, a cartridge holder insert 204, a base 205, a servo motor 207, a cartridge cam shaft 208, a flex printed circuit board (PCB) 209, a lock button 210, a cover insert sprint 212, fans 213, cover air insert 216, cartridge body side 217, flex PCB cover 219 and PCB board 220. The cartridge holder cover insert 203 can be opened to insert the fragrance/ sterilization cartridges 111 into the fragrance diffuser assembly 201. Once inserted, the cartridge holder cover insert 203 can be closed to secure the fragrance cartridges 111 in the fragrance diffuser assembly 201 during normal operation. The cartridge holder cover insert 203 can also be opened to remove and replace the fragrance cartridges 111 if they are empty or need to be replaced.

[0048] The flex PCB 220 can have sensors which detect RFID tags 187 on the fragrance cartridges 111. The RFID tags 187 can be checked to confirm that the fragrance cartridges 111 are authentic. More specifically, the PCB 220 can include a transmitter and receiver that can communicate with a server. The information from the RFID tags 187 is transmitted by the PCB 220 to the server and compared to a database of authentic and unused fragrance cartridges 111. If the fragrance cartridge I l l is verified as being authentic and not a 3^rd party recycled or refurbished fragrance cartridges 111, the server can transmit a verification signal to the controller mounted on the PCB 220 that will allow the fragrance diffuser assembly 201 to function normally. However, if a fragrance cartridge I l l is not verified by the server, the controller on the PCB 220 can prevent the fragrance diffuser assembly device 220 from functioning or alternatively, the PCB 220 can prevent the unverified fragrance cartridge 111 from being used. The status of the fragrance diffuser assembly can be transmitted to a user interface so that an operator can be instructed to remove and replace an unverified fragrance cartridge 111.

[0049] The cartridge cam shaft 208 is an elongated shaft having four cams that extend radially outward from the cartridge cam shaft 208. The four cams on the cartridge cam shaft 208 can be rotationally offset from the other cams. Each cam can be positioned under each of the fragrance cartridges 111 in the diffuser assembly 201. The cartridge cam shaft 208 can be coupled to the servo motor 207 which is controlled by the controller mounted on the PCB 220. The controller can cause the servo motor 207 to rotate the cartridge cam shaft 208 to a specific rotational position so that one of the cams opens the internal valves of one of the fragrance cartridges 111 while all other internal valves of the other fragrance cartridges 111 remain closed. [0050] When the fragrance diffuser assembly 201 receives instructions to disperse a first fragrance or disinfectant, the controller can cause the servo motor 207 to rotate the cartridge cam shaft 208 to the position that opens the requested fragrance cartridge 111. Once the requested cartridge 111 is open, the controller can actuate the fan(s) 213 which causes air to flow into the cartridge holder through air inlet vents 226 in the side of the holder 214 to the bottom of the open cartridge 111. The air flows up through the open fragrance cartridge 111 to the top portion of the cartridge holder cover 202 and the outlet vent 223. The outlet 223can have a threaded or a coupling connection that can be connected through tubing to a vehicle environmental control system. Dry particles from the open fragrance cartridge 111 are distributed into the vehicle or other space to provide fragrances to the passengers or sterilization particles to the interior passenger volume of the vehicle. After a predetermined time period, the controller causes the fan(s) 213 to stop and causes the cartridge cam shaft 208 to rotate to a position where all of the internal valves in the cartridges 111 are closed.

[0051] FIGS. 6-11 illustrate an embodiment of a fragrance cartridge 111 that can be used with the diffusions systems described and illustrated above with reference to FIGS. 1-5. FIG. 6 illustrates a side view of an embodiment of a fragrance cartridge 111. In the illustrated embodiment, the fragrance cartridge 111 has an elongated hollow structure. In an embodiment, the length of the fragrance cartridge can be about 3.5 to 4 inches long. FIG. 7 illustrates an exploded view of an embodiment of a fragrance cartridge 111. The fragrance cartridge 101 can have an elongated shell body 189 which has a hollow cylindrical structure with open ends. A cartridge base 191 is attached to the bottom of the elongated shell body 189 which has a circular inlet orifice. The upper inner surface of the circular inlet orifice in the cartridge base 191 that can function as an inlet sealing valve. A removable cartridge basket 183 having an inner volume is placed within the shell body 189. The outer surface of the removable cartridge basket 183 closely matches the inner surface of the shell body 189 so that the cartridge basket 183 can slide axially within the shell body 189. The cartridge basket 183 can have a plurality of slots that prevent the fragrance bead substrates from falling out of the cartridge basket 183 but allow air to flow through the cartridge basket 183. A cartridge base insert 173, a spring 177, and a basket stem 193 can be coupled to the bottom of the cartridge basket 183. The basket stem 193 can extending downward from the bottom center of the cartridge basket 183 and a conical portion of the basket stem 193 pressed against a portion of the cartridge base 191 can form the lower valve. [0052] A cartridge basket cover 181 having slots is placed on the upper end of the removeable cartridge basket 183 where the slots are narrower than the outer dimensions of the dry fragrance beads. In an embodiment, a color-coded identification ring or label on the shell 189 can identify the dry fragrance beads in the fragrance cartridge 111. The cartridge cap 175 can have a circular outlet opening and a sealing surface on the upper side of the cartridge cap 175. A cartridge cap 175 can also include a circular structure attached to a center rod which extends downward which is coupled to the cartridge basket cover 181. A spring 177 is compressed and placed between a lower surface of the cartridge cap 175 and an upper surface of the cartridge basket cover 181.

[0053] When the fragrance cartridge 111 is in the closed position, the valves can be pressed against a circular sealing surfaces at the inlet cartridge base 191 and the outlet at the cartridge cap 175. The compressed springs 177 holds the upper valve 171 against the upper surface of the cartridge cap 175 sealing surface and the removable cartridge basket 183 in a lowered within the cartridge shell body 189. The compressed springs 177 holds the upper valve against the upper surface of the cartridge cap 175 sealing surface. When the basket stem 193 is pushed into the fragrance cartridge 111, the valve moves up to open the inlet valve at the cartridge base 191 so that air can flow through the inlet and through the slots formed in the cartridge basket 183 to the fragrance beads (not shown) to the outlet valve 171 that is also raised above the sealing surface of the cartridge cap 175.

[0054] The outer cross section of the fragrance cartridge 111 can have a trapezoidal shape having four sides and rounded corners. The fragrance cartridge 111 can be uniform in cross section across the length. Each of the side surfaces can be between about 0.5 to 1 inch. The trapezoid cross section can have two roughly parallel surfaces sides coupled to two sides which can be tapered inward. The two parallel sides can have the widest and the narrowest sides. When the fragrance cartridges 111 are inserted into the mobile digital aroma apparatus, the narrowest sides of the fragrance cartridges 111 face the center of the apparatus and the widest sides of the fragrance cartridges 111 face outward from the mobile digital aroma apparatus. [0055] FIG. 8 illustrates a cross section view of an embodiment of a fragrance cartridge 111 in the open position and FIG. 9 illustrates a cross section view of an embodiment of fragrance cartridge 111 in the closed position. As illustrated in FIG. 8, the internal springs 177 will normally hold the fragrance cartridge 111 in a closed position with the fragrance media such as fragrance infused beads 113 contained within a cartridge basket 183 sealed at the top cartridge cap 175 and the bottom cartridge base 191. When the fragrance cartridge 111 is actuated, an actuator mechanism can press the stem 193 at the bottom of the fragrance cartridge 111 up, which can open the valve seals at the top cartridge cap 175 and the bottom cartridge base 191of the fragrance cartridge 111. FIG. 10 illustrates a bottom view and FIG. 11 illustrates a top view of the fragrance cartridge 111.

[0056] When the fragrance cartridge I l l is placed in a slot in the mobile digital aroma apparatuses illustrated in FIGS. 1-5, the aroma apparatuses can have actuators which pushes the push the stem 193 extending from the bottom base 191 of the fragrance cartridge 111 to open the fragrance cartridge as shown in FIG. 9 and described above. The mobile digital aroma apparatus can then direct air into the bottom of the fragrance chamber. Dry fragrance particles from the fragrance beads are mixed with the air which flow out of the open valve at the top of the fragrance chamber. The aroma apparatus can be located close the user who can then enjoy the fragrance emitted from the aroma apparatus. Once the fragrance emission is complete, the aroma apparatus can stop the flow of air through the fragrance cartridge. The aroma apparatus can allow the center rod extending to extend down away from the bottom of the fragrance cartridge which causes the spring to lower the fragrance chamber in the fragrance chamber so the lower end of the fragrance chamber is against the lower base cap and the valve pressed against the inner diameter of a hole in the upper cap which closes the lower inlet and the upper outlet. [0057] With reference to FIGS. 1-5, when the mobile digital aroma apparatus receives a fragrance output signal, the processor can transmit control signals to the servo stepper motor which can respond by rotating a revolving plate 139 which can have raised surfaces which can push the stem extending from the selected fragrance cartridge 111 up. This stem movement causes the fragrance cartridge to open. Simultaneously, the fan(s) 135 at the bottom of the cup body 103 can be turned on to create an air flow through the opened fragrance cartridge 111. The dry fragrance particles can mix with the air flow and the fragrance particles can flow up and out of the fragrance cartridge 111 and the mobile digital aroma apparatus 101 where the fragrances can be enjoyed by the system user. When the fragrance dispersion is complete, the fan(s) 135 can stop and the revolving plate 139 can be rotated to allow the stem to move down to close the fragrance cartridge 111. The mobile digital aroma apparatus 101 can then wait for the next fragrance emission control signal.

[0058] With reference to FIG. 7, a smart chip 187 can be mounted on an outer surface of the fragrance cartridge 111. This smart chip 187 can be read by the mobile digital aroma apparatus when the fragrance cartridge I l l is placed into the fragrance slot in the aroma apparatus by a smart chip readers. In an embodiment, the smart chip 187 can be ID tags that can provide identification and fragrance information. The mobile digital aroma apparatus can read the smart chip 187 ID of the fragrance cartridge which can be used for fragrance cartridge authentication. If the fragrance cartridge 111 fails the authentication the mobile digital aroma apparatus can function as described. However, if the fragrance cartridge 111 fails the authentication the mobile digital aroma apparatus can identify the fragrance cartridge as a counterfeit and prevent the use to the counterfeit fragrance cartridge 111 until the counterfeit fragrance cartridge has been removed. When authentication fails, the digital aroma apparatus can stop system functionality for just the counterfeit fragrance cartridge 111 alone while allowing authenticated fragrance cartridges 111 to function normally.

[0059] With reference to FIGS. 12-18, other embodiments of digital aroma apparatuses are illustrated which can be home, office, or other environmental application based rather than mobile devices.

[0063] As discussed above, in some embodiments, the mobile digital aroma apparatus can read the ID information for the smart chip on each of the fragrance cartridges. The ID information can include a unique ID data and can also include the date of manufacturing. The ID information can be transmitted to a system server which can compare the ID information to a database of valid IDs. If the ID is valid, then the server can transmit an authentication confirmation signal back to the mobile digital aroma apparatus through the smartphone and the fragrance cartridge can be used as described. However, if the ID is compared to the ID information to a database of valid IDs and is found to not be valid then the server can transmit an authentication failure signal through the smartphone to the mobile digital aroma apparatus which can then prevent the mobile digital aroma apparatus from using the fake fragrance cartridges. [0064] In other embodiments, a mobile software application can be running on the user’s smartphone that runs a fragrance cartridge authentication algorithm. In this embodiment, the ID information is read by the mobile digital aroma apparatus that transmits the ID information to the smartphone which then runs the authentication algorithm to determine if the fragrance cartridge is authentic. If the ID is determined to be valid, then the smartphone can transmit an authentication confirmation signal back to the mobile digital aroma apparatus and the fragrance cartridge can be used as described. However, if the ID information fails the authentication algorithm then the smartphone can transmit an authentication failure signal to the mobile digital aroma apparatus which can then prevent the mobile digital aroma apparatus from using the fake fragrance cartridges. In an embodiment, the ID mechanism that is permanently mounted on each fragrance cartridge can be a radio frequency identification (RFID) tag and the mobile digital aroma apparatus can include RFID readers that can read the RFID tags for each of the fragrance cartridges in each of the fragrance cartridge slots. The RFID tag can transmit ID identification can be used for described fragrance cartridge authentication purposes.

[0065] In other embodiments, the fragrance cartridge data from the ID tags can be used for other purposes in addition to authentication for system operations. The ID information can be displayed on the user interface of the mobile application program running on the smartphone or on a display on the mobile digital aroma apparatus so that the user can know what fragrances are available as well as information about their fragrance use and history. The user can then select the desired fragrance and control the mobile digital aroma apparatus to emit the user selected fragrances. The mobile application program running on the smartphone and/or the mobile digital aroma apparatus can also know the number of fragrance dispersions from each of the fragrance cartridges and this information can be stored in the server, mobile application program and/or the mobile digital aroma apparatus. In different embodiments, different fragrance cartridges can have different total fragrance dispersions which can be imperially derived based upon the quantity of fragrance beads and the type of fragrance being used. The system can then count the number of dispersions and determine the number of dispersions remaining for each fragrance cartridge. The remaining dispersion information can be used to provide current fragrance levels of the fragrance cartridges. The system can display the remaining fragrance dispersions available and issue warnings through a display on the smartphone or the mobile digital aroma apparatus when there is a predetermined number or percentage of fragrance dispersions that are available. For example, in an embodiment, the system can provide a warning when there is 40, 20, 10, and 5 fragrance dispersions left in each of the fragrance cartridges. Alternatively, the system can provide a warning when there is 20%, 10%, 5%, and 1% fragrance dispersions left in each of the fragrance cartridges. Once the fragrance dispersions have been completely consumed, the system (server, mobile app, and/or the mobile digital aroma apparatus) can prevent further use of each of the fragrance cartridges. [0066] Each fragrance cartridge can have an air inlet at the bottom and an air outlet at the top. The fragrance cartridge can have a color coded identification ring and/or a scent name label which can correspond to a specific fragrance. In this example, the color ring ID can be yellow which can be associated with the fragrance “Havana Night Rejuvenate.” This fragrance cartridge can include the ingredients natural lemon and tonka bean. The identified fragrance can be in the form of dry fragrance particles which are infused into dry beads which are placed in the fragrance cartridge. The dry beads are larger than the slots or orifices in the inlet and outlet of the fragrance cartridges so that the dry beads do not fall out of the fragrance cartridge when in the open position.

[0067] The inventive system can provide an intelligent, data-centric, cloud-based server platform for providing wellness and health capabilities in rideshare vehicles to eliminate bad odors, emit ingredients to reduce microbial aerosols such as bacteria and viruses including (COVID-19), and relieve motion sickness in vehicles. In an embodiment, the mobile digital aroma apparatus can be part of a computer network. The mobile digital aroma apparatus can communicate with a software application program running on a mobile computing device such as a smart phone. The connected components of the system can include coordinate the operations and communications of the intelligent cartridges and in-vehicle diffusion devices to a cloud-based computer server system. The system server(s) can receive use, location, preference, fragrance usage, user data, and other data from the mobile digital aroma devices. The system servers can process and correlate data including: device usage, user profiles and user preferences from actual consumer device. The data can be generated across an entire population of digital aroma devices and fragrance cartridges.

[0068] As described above, the mobile digital aroma apparatus can hold multiple fragrance cartridges, which are filled with fragrance beads which can be used for various purposes. The fragrances of the fragrance cartridges are actuated and the desired fragrance is output from the mobile digital aroma apparatus. In addition to controlling the mobile digital aroma apparatus to output the desired fragrance, the fragrance emissions can also be used for other purposes such as: mood changes, motion sickness reduction, body odor control, and antibacterial and/or anti-viral processing of the confined space.

[0069] In some embodiments, the fragrance cartridges can be used for controlling a user’s mood. In this embodiment, blends of dry fragrance beads can be used altering user moods. The user can then select the desired mood and the fragrances emitted from the digital aroma devices can be used to emit the fragrances associated with the selected mood. For example, if a user wants the fragrance system to transition from an energized state to a relaxed state on-demand, the mobile digital aroma apparatus could have emitted a fragrance associated with energization and then the user interface is used to input a relaxed mood request.

[0070] For example, the mobile digital aroma apparatus can be particularly useful for confined spaces such as transportation vehicles. The mobile digital aroma apparatus can also be used for ridesharing system for use in moving vehicles including: cars, buses, trains, airplanes, boats, etc. Many people drive personal vehicles and the mobile digital aroma apparatus can be used to emit the desired fragrance for the desired purpose by the driver or passenger. In other embodiments, the mobile digital aroma apparatus can be used for commercial purposes to enhance the vehicle experiences for passengers and operators.

[0071] In different embodiments, the processing of fragrance use data can be collected and analyzed by the mobile digital aroma apparatus and computer server networks. The fragrance cartridges are created by fragrance designer. Once the fragrances are created, the fragrance beads are placed into the fragrance cartridges. The filled fragrance cartridges are then placed in the aroma apparatus. The aroma apparatus filled with fragrance cartridges is shipped to the end user. The user’s smartphone is paired with the aroma apparatus which can communicate through the internet with servers. The mobile digital aroma apparatus can be verified through an authentication process through the smartphone which communicates with the server. Once the aroma apparatus passes verification, the user can control the operation of the aroma apparatus using a mobile application running on the user’s smartphone. The mobile application can monitor the operations of the aroma apparatus and record the user’s fragrance emission information for the aroma apparatus. The user’s aroma apparatus use data can be transmitted from the smartphone to the system server which can capture all fragrance diffusions for many aroma apparatuses. The server can analyze the fragrances for popularity, region, feedback, etc. The server can also determine when the fragrance cartridges are depleted and the server can send reorder notifications to the smartphone.

[0072] WELLNESS RIDE - A feature of the present invention is a cloud platform rideshare system with services that can provide users with a state of wellness and well-being.

The fragrance dispersion system can incorporate malodor technology which can emit ingredients to reduce microbial aerosols such as bacteria and viruses including COVID-19. This can be particularly useful for shared confined spaces such as public transportation ride sharing vehicles. For example, odors can be difficult to hide and are often to blame for bad passenger experiences. Other bad experiences can include motion sickness, bacteria and virus exposure and fears. For the transportation providers, bad user experiences can result bad service reviews which can be very bad for the service providers’ businesses. The inventive system can be configured to deliver an on-demand, multi-scent experience that can improve passengers’ moods, relieve motion sickness, reduce airborne bacteria and viruses including Covid- 19, bad odors, and create a healthier “wellness ride” using intelligent cartridges with different functional scent and antivirus cartridges. This inventive platform can be used by rideshare, car rental, and other transportation companies to add scent diffusion systems quickly and conveniently into their fleets and increase revenue from every ride.

[0073] The inventive system can implement a process for utilizing the wellness ride feature. In an embodiment, the fragrance dispersion system can perform mood mapping which can include three types: scent mapping to state of mind where fragrances change the user’s state of mind, scent mapping to behaviors where fragrances change the behavior of the user, and scent mapping to emotional state where the fragrances can enhance the user’s emotional well being. While many fragrances can have a universal mood mapping, in some cases the mood mapping can be influenced by cultural differences where some fragrances are well known and associated with positive feelings in specific cultures such as an incense fragrance in Asia may be well known while incense is much less common in North America.

[0074] In order to perform the mood mapping, the fragrance dispersion system can be used to perform experimentation where users receive natural element fragrance exposure and provide feedback which can be recorded and stored in a database coupled to the server, concentration, etc. In an embodiment, the system can measure biometric responses of the users immediately after being exposed to the fragrances. The biometric measurements can include: blood pressure, heart rate, perspiration level, muscle tension, etc. The system can also have a UI which allows the user to input feedback. For example, the UI may include feedback inputs such as: relaxation, rejuvenation, energization, excitation, focus, etc. This mood mapping data can be analyzed so that patterns can be identified based upon common fragrance responses. This mood mapping data can be stored in a database coupled to the server.

[0075] The UI for the inventive system may have moods inputs rather than or in addition to fragrance inputs. When the user inputs the desired mood to the UI, the fragrance dispersion system can respond by emitting a fragrance that has been mapped to that mood. Examples of different fragrances associated with moods include citrus and fresh based fragrances which promote alertness, lavender fragrances can invoke calmness and woodsy fragrances can promotes restoration and rejuvenation. Additional examples of fragrances associated with moods are listed and described below.

[0076] In an embodiment, the inventive fragrance dispersion system can be customizable. The user may request a specific mood through the UI and the fragrance emitted by the system may not provide the desired effect or result in an adverse reaction. The UI can have an input that can allow a user to provide feedback to the system. If the fragrance is not providing the desired effect the user can push a button on the UI informing the system that the fragrance is not working. The system can immediately cease the output of the fragrance and can reconfigure the association between the mood and the fragrance for the user in a user profile database. When the mood is input in the future, the system will provide an alternative fragrance for the desired mood input. Similarly, the user may notice certain moods when smelling various fragrances. The UI can have an input that can list various moods and the user can input the mood that is experienced when the fragrance is smelled by the user. The system can then associate this fragrance with the input mood in a user profile database. When the user selects the mood through the UI in the future, the system can emit the fragrance associated with that mood by the user.

[0077] In an embodiment, the inventive fragrance system can have odor sensors which can detect various odors including human bio-markers, smoke, plastic, vomit, and body odors. There can be various different types of malodors which can be divided into two basic types: nitrogen compounds and organic acids. Nitrogen compounds include: garbage, product base, seafood, smoke, urine, etc. Organic acids include: hair, scalp, pet, sweat, vomit, and other odors. The fragrance system can solve this malodor problem by developing and/or using known reactive molecules that combine with the malodor particles to eliminate the malodor in the air. The efficacy of the reactive molecules can be tested by exposing people to malodors and treating the ambient air with the reactive molecules. The user can provide feedback through a UI which allows the user to confirm or deny that the perceived intensity of the malodor is reduced in the presence of the counteracting fragrance ingredients. [0078] The fragrance system can have an odor delivery and detection system. The delivery system that can have a fan which causes ambient particles to be collected or received by the system. The detection system can have a sensor for detected particles collected by the delivery system. When particles contact the sensor, the sensor can respond by producing a change of electrical properties. The sensor can be sensitive to all volatile molecules and the change in electric properties can be specific and unique for each volatile molecule. In an embodiment, the sensor can include a sensor arrays that react to volatile compounds on contact and the absorption of volatile compounds on the sensor surface causes a physical change of the sensor. A specific response is recorded by the electronic interface transforming the detected odor signal into a digital value. Recorded data are then computed based on statistical models.

[0079] In an embodiment, the described system can use odor sensors that use olfactory receptors proteins cloned from biological organisms that bind to specific odor molecules and can be used to perceive odors at a very high sensitivity: femtomolar concentrations. The odor sensors can include: metal-oxide-semiconductor (MOSFET) devices such as a transistor used for amplifying or switching electronic signals that works on the principle that molecules entering the sensor area will be charged either positively or negatively, which should have a direct effect on the electric field inside the MOSFET. Introducing each additional charged particle will directly affect the transistor in a unique way, producing a change in the MOSFET signal that can then be interpreted by odor pattern recognition computer systems. Each detectable molecule can have its own unique signal that can be stored in an odor particle database that is coupled to a computer system to detect known particles and odors.

[0080] In other embodiments, the odor sensors can use conducting polymers that are organic polymers that conduct electricity, polymer composites that are similar in use to conducting polymers but formulated of non-conducting polymers with the addition of conducting material such as carbon black, quartz crystal microbalance that are used to measure mass per unit area by measuring the change in frequency of a quartz crystal resonator and this mass data can be stored in a database and used for future reference, and/or surface acoustic wave (SAW) microelectromechanical systems (MEMS) which rely on the modulation of surface acoustic waves to sense a physical phenomenon. Some odor sensor devices can combine multiple sensor types in a single device, for example polymer coated QCMs.

[0081] In some embodiments, the malodor sensor can be similar to a breath analyzer sensor. Any ethanol present in their breath is oxidized and converted into acetic acid at the anode: CEFCEEOH^g) + EEOQ) — CHaCCEHQ) + 4H⁺(aq) + 4e“ At the cathode, atmospheric oxygen is reduced: 02(g) + 4H⁺(aq) + 4e“ — EEOQ) The overall reaction is the oxidation of ethanol to acetic acid and water. CHaCEEOHQ) + 02(g) — CH3COOH(aq) + H2O(1) The electric current produced by this reaction is measured by a microcontroller, and displayed as an approximation of overall blood alcohol content of the ambient air.

[0082] The odor sensor can be coupled to the fragrance system and when specific malodors stored in the database are detected, the fragrance system can respond by emitting fragrances and/or particles which can eliminate the detected odors. In some embodiments, the emission of anti-malodor particles and/or anti-viral particles can be combined with the fragrance emissions or they can be emitted from a dedicated anti-malodor or anti-viral cartridge.

[0083] The emission quantity of the counteracting fragrances and/or particles can be proportional to the quantity of malodors detected by the sensor. Alternatively, the system can continue to intermittently emit the anti-malodor particles and/or anti-viral particles while detecting the concentration of malodors and virus particles. The system can continue to intermittently emit the anti-malodor particles and/or anti-viral particles until the detected malodors and virus particles drop below predetermined concentration values in the vehicle. In an embodiment, the odor fighting fragrance can include a fragrance as well as malodor ingredients which can have a chemical reaction that can neutralize the odor particles.

[0084] It is well known that viruses such as Coved 19 are spread by airborne droplets and aerosols that originate from infected individuals. The droplets are expelled into the air through a cough or sneeze and can infect another person who encounters them at close range. Droplets are larger and do not remain in the air for very long, quickly settling to the ground or another surface. However, aerosols are smaller and remain suspended for longer up to three hours. Aerosols will rapidly dry out and disperse over time. However, this long suspension time makes it possible for a person to be exposed to enough viral particles, known as the infectious dose, to be infected. In an embodiment, the aerosol transmission can be reduced by having an air flow through the vehicle and a HEPA filtration system. Drivers and passengers of ride sharing vehicles can also wear masks to prevent the production of droplet and aerosol emissions.

[0085] For rideshare vehicles, the fragrance dispersion system can provide an on-demand sterilization process. When a rideshare vehicle is requested, the future rider can select a car and the system will provide an estimated time of arrival. During the ride request process, the system UI on a rider’s mobile computing device can also allow the option of sterilizing the vehicle and the system may charge the user an added fee for this option which can be paid through the ride sharing billing system. If the user selects the sterilization option, the fragrance system in the hailed vehicle can perform a cleansing and fragrance procedure by emitting the anti-malodor particles and/or anti-viral particles while the vehicle is in route towards the rider. The quantity of anti-malodor particles and/or anti-viral particles emitted during sterilization can be variable based upon several factors which can be input or measured by the fragrance system including: passenger space, air flow, temperature, and detected malodor and/or virus contamination. The anti-malodor particle and/or anti-viral particle emission can be proportional to the passenger space with smaller vehicles requiring less quantity than larger vehicles. The antimicrobial effects of the particles can be enhanced with temperature. In an embodiment, the fragrance dispersion system can measure the temperature of the passenger space and adjust the particle emission quantity accordingly or alternatively, the vehicle can increase the passenger area temperature and perform the anti-viral particle emission at an elevated temperature for improved cleaning performance. The antibacterial activity of antimicrobial agents is significantly but differentially enhanced by increasing the ambient temperature and using high concentrations. [0086] After performing the anti-viral particle emission process, the fragrance dispersion system can emit the desired fragrance when the passenger is picked up or just before the user enters the vehicle so that the user can experience the desired fragrance. In other embodiments the sterilization process can be performed immediately after the user leaves the ride vehicle so that the passenger spaces will be sterilized for the next rider. The anti-malodor particles and/or anti-viral particles can include natural known ingredients.

[0087] The health of vehicle passengers is a critical requirement for safe use of ride sharing services. Sterilization molecules can be developed which can be tested on bacteria and viruses in a laboratory environment. Successful sterilization molecules can then be tested on vehicles and people. If these materials are successful in vehicles, the system cartridges can be filled with the sterilization molecules. In commercial use, the fragrance system can periodically release anti-pathogen infused scents and/or particles into the vehicle cabin. The system can also emit the sterilization molecules between different passengers. Through this process, the fragrance dispersion systems can reduce the risks of infections of viruses such as Coved 19. [0088] The described fragrance cartridges can be particularly useful with ridesharing vehicles. The scent fragrances are created and the fragrances can be infused into beads which are placed in smart fragrance cartridges. The smart fragrance cartridges can be inserted into mobile personal fragrance dispersion systems or embedded fragrance dispersion systems that can be incorporated into vehicles. The cartridge filled fragrance dispersion systems can then be sent to the rideshare companies and their drivers. The embedded fragrance dispersion systems that can be incorporated into vehicles climate control system and the mobile personal fragrance dispersion systems can be placed in the vehicles. In an embodiment, the fragrance dispersion systems can communicate with a cloud based server and perform a fragrance cartridges and/or fragrance dispersion system authentication process where identification information is detected and read from the fragrance cartridges. If the cartridges fail the authentication process, the server can prevent the fragrance dispersion system from using the cartridges. The fragrance cartridge authentication failure can result from detecting a fragrance cartridge ID that is not in the system database, the use of a known fragrance cartridge ID that exceeded a predetermined number of dispersions which may indicate that the cartridge was refilled with unauthorized fragrance media. If the cartridges passes the authentication process, the server can allow the fragrance dispersion system to use the cartridges.

[0089] After authentication, the rider passenger can control the fragrance dispersion system by a mobile computing device such as a smart phone which can communicate with the fragrance dispersion system through the cloud server. The passenger can use the fragrance dispersion system and enjoy output fragrances. The user’s interactions with the fragrance dispersion system can be recorded and sent to the cloud based server which can capture all diffusions and fragrance reorders. The cloud based server can then analyze the data from all of the fragrance dispersion system users and may compare the results based upon location, and user demographics including: age, gender, nationality, etc. The cloud based server can then make recommendations and predict future orders based upon the system use data.

[0090] The fragrance dispersion systems can be used by the ride sharing drivers and riders to eliminate bad smalls caused by body odor, cigarette smoke and malodor biomarkers. The fragrance dispersion systems can used to reduce malodors within ride sharing vehicles. A vehicle passenger can naturally emit body odor. An odor sensor in communication with the fragrance dispersion system can detect the body odor. The fragrance dispersion system having a malodor cartridge can respond to the odor detection by diffusing anti-malodor particles that can correspond to the detected malodor which can be sweat, body odor, cigarette smoke, bad human biomarkers, etc. The fragrance dispersion systems can communicate with system servers through cloud network and the diffusion data can be captured and analyzed. The diffusion data can include all malodor incidents, fragrance and/or sterilization popularity, cartridge reorders, etc. and this data can be used to improve the anti-malodors in the vehicle. The odor sensor unit can also determine if the malodor in a vehicle has created a situation where the malodor is beyond a maximum acceptable level. For example, if the detected organic VOC level is above the maximum acceptable level the cloud based server can instruct the driver UI to take the vehicle out of service so that a cleaning can be performed. Once the vehicle has been deodorized and the detected organic VOC level is within the acceptable malodor level, the vehicle can be returned to service and the described process can be repeated.

[0091] In an embodiment, a mobile app running on a computing device can have a UI that has an input for nausea level. For example, the user can input a nausea level and in response, the fragrance dispersion system can emit an anti-nausea ingredient(s) which can help to relieve the user’s nausea. If the user feels nothing the user can input a nausea level 0. If the user starts yawning or feeling clammy and/or lightheaded, the user can input a nausea level 1. If the user starts burping and/or feeling lethargic or dizzy, the user can input a nausea level 2. If the user feels like he or she has a twisted stomach, feels drowsy or starts salivating, the user can input a nausea level 3. If the user feels like vomiting, has a spinning head, feels exhausted and/or disoriented, the user can input a nausea level 4. If the user is vomiting, experiences head tumbling, and extreme sweating, the user can input a nausea level 5. In other embodiments, other levels of nausea can be used for the inputs into the UI. The mobile app can receive the nausea input and transmit a control signal to the output of the fragrance dispersion system which can immediately emit anti-nausea ingredients. The anti-nausea ingredients can include natural elements that have been tested and proven to reduce or eliminate motion sickness for people who have mild to medium motion sickness sensitivity. The quantity of the anti-nausea ingredient(s) emitted by the fragrance system can be proportional to the passenger’s nausea level. If the user continues to input nausea inputs, the fragrance system can continue to emit anti-nausea ingredients. In some extreme situations, the system may instruct the driver to slow down or stop the vehicle as a possible means for curing the user’s nausea.

[0092] Both drivers and passengers safety and health is paramount for health. The inventive fragrance dispersion system can emit anti-bacterial and/or anti-viral materials on demand to perform sterilization of a occupant area of a vehicle. The anti-bacterial and anti-viral materials can be natural ingredients that can be infused into beads in the sterilization cartridges. In some embodiments, the anti-bacterial and anti-viral materials can be combined with fragrance materials in the fragrance cartridges with can provide a combined fragrance with sterilization within a vehicle. When the anti-bacterial and anti-viral materials are emitted by the fragrance dispersion system they come into contact with the bacteria and viral materials. The anti-bacterial and anti-viral materials can eliminate the airborne bacteria and viruses. By periodically releasing these anti-pathogen infused scents into a rideshare vehicle’s cabin, the risk of infection can be lowered. This sterilization process can be especially useful in ridesharing vehicles between passenger pickups. In some embodiment, the sterilization process can be performed just before the passenger(s) enters the vehicle and/or just after the passenger(s) leaves the vehicle.

[0093] The inventive system can be used with mobile computing devices and system users can utilize UIs to control the fragrance system. Passenger users can interact with the UI to control the fragrance system which can be integrated into a rideshare app. 1. A mobile app for controlling the system is downloaded from an app server to a computing device and the mobile app is opened by the passenger user. 2. The passenger user opens the app and can log in or register. 3. With reference to FIG. 23, the mobile app UI can display the benefits of the vehicle sterilization and scent fragrances. The UI can have a button to add the vehicle processing to the passenger user’s vehicle ride share. 4. With reference to FIG. 24, once the passenger user selects vehicle processing, the UI can display a listing of vehicle processing options including scent preferences and fragrance intensity level. 5. With reference to FIG. 25, once the passenger user inputs the processing preferences, the UI can display a processing status for the ordered vehicle. 6. With reference to FIG. 26, when the vehicle processing is finished the UI can display a message indicating that the vehicle processing is complete.

[0094] The driver user who is providing the ride to the passenger can also interact with a UI to control the fragrance system which can be integrated into a rideshare app. 1. A mobile app for controlling the system is downloaded from an app server to a driver computing device and the mobile app is opened by the driver user. 2. The driver user opens the app and can log in or register. 3. With reference to FIG. 27, the mobile app can display ride requests and the UI can have a button to accept the ride. 4. With reference to FIG. 28, once the ride is accepted by the driver, the UI can display a listing of vehicle processing options that have been selected by the user. The user can press the “start” button to perform each of the passenger requested processes. In this example, the user has selected “sanitize” and the user has pressed the start button to cause the diffuser to start the sanitization process. 5. With reference to FIG. 29, once the sanitize processing is complete, the diffuser can emit the requested fragrance. The UI can display a stop button and if necessary, the driver can click the stop button to stop the diffusion processing. 6. With reference to FIG. 30, when the vehicle processing is finished the UI can display a message indicating that the vehicle processing is complete.

[0095] Fragrance diffusers can be used in vehicles as well as fixed structures such as homes, offices, stores, etc. These fix location diffusers can also communicate with servers and UIs on the user’s mobile phone computing devices. FIGS. 37 and 38 illustrate examples of an embodiment of a UI for a home fragrance diffuser. The UI can display the name or location of the diffuser, a control input for controlling the fragrance intensity output and the selectable name of the selected fragrance cartridge (Aperitivo in Terrazza) and an activation button. In the illustrated embodiment, the user can slide the slider to a desired output intensity and the desired output duration. The user can also swipe left or right on the fragrance controls to select a desired fragrance. Once the user has selected the fragrance, intensity and duration, the user can press the activation button. The mobile computing device can transmit the fragrance signal to the diffuser that can respond by emitting the selected fragrance at the selected intensity and duration. The UI can also include controls for scheduling the diffusion outputs. With reference to FIG. 43, the diffuser can be programmed to output a desired fragrance, at specified times and days. In this example, the user has programmed the selected fragrance on a schedule Monday through Friday from 8:00 to 18:00 with an intensity of 8. [0096] With reference to FIG. 39, as discussed, in some embodiments the fragrance diffusers can transmit fragrance use data to a server which can process the fragrance use data and provide use information which can be display on a display screen in a graphical manner. An over view portion 441 of the UI can display the number of active diffusion devices that are currently associated with the user, the number of non-active diffusion devices, the number of diffusion devices that are currently emitting a fragrance, and a number of fragrance cartridges that have a low level of fragrance remaining on the bead substrates. The filter portion 447 of the UI can allow the user to control the duration of time for the fragrance use data. In this example, the fragrance data is displayed over a one week period Sunday - Saturday for each of the graphical fragrance data displays.

[0097] The wellness ride portion 443 of the UI can display the number of diffusions of fragrance and sanitization cartridges from a fragrance diffuser. In the illustrated example, the fragrance diffuser emitted one fragrance scent diffusion on Sunday, two fragrance scent diffusions on Monday, three fragrance scent diffusions on Tuesday, one fragrance scent diffusion on Wednesday, one fragrance scent and two sanitizing diffusions on Thursday, five fragrance scent and one sanitizing diffusions on Friday and no diffusions on Saturday. A scent diffusion portion 445 of the UI can identify the specific types of diffusions emitted by the diffuser. In this example, the diffuser emitted five calm fragrance diffusions, three malodor fragrance diffusions, five alert fragrance diffusions, and three antivirus sanitizing diffusions. In the number of diffusions by hour section 449, a graphical representation of the times and days that the diffusions occurred. On Sunday the one diffusion occurred at 11, on Monday the diffusions occurred at 10 and 12, on Monday two diffusions occurred at 14 and one diffusion occurred at 22, on Wednesday one diffusions occurred at 11, on Thursday one diffusion occurred at 13 and two diffusions occurred at 14, on Friday two diffusions occurred at 11 and four diffusions occurred at 14. The fragrance diffuser may hold four fragrance cartridges and the scent supply portion 451 of the UI can display the scent levels for each of the fragrance cartridges. In this example, the alert fragrance cartridge is 100% full, the antivirus fragrance cartridge is about 60% full, the calm fragrance cartridge is about 95% full, and the malodor fragrance cartridge is about 70% full.

[0098] FIG. 31 illustrates a diagram showing communications paths between a customer’s computing device 381, the driver’s computing device 383, the fragrance system server 389, the ride share driver’s server 387, and the fragrance diffuser 385. In this example, with the driver’s computing device 383 phone configured as an internet router for communications with the fragrance diffuser 385. The customer’s mobile app can run on the customer’s computing device 381 and be used to request the vehicle processing which is transmitted through a wireless network to the ridesharing server 387 which communicates with the scent server 389. The rideshare server 387 then communicates with the driver’s app running on the driver’s computing device 383 which controls the fragrance diffuser 385 to perform the requested fragrance output processing. The fragrance diffuser 385 can then transmit data back through the driver’s computing device 383 through the wireless network back to the scent server 389. The computing devices 381, 383 can communicate with the servers 387, 389 through a wireless cellular network as illustrated but communications may also include WiFi Network communications. For example, the driver’s computing device 383 can be set to share internet access over WiFi. The driver’s computing device 383 phone can be seen by other connected devices and can function as a WiFi router so that the fragrance diffuser 385 is connected to the rideshare server 387 and the scent server 389 through the driver’s computing device 383 phone’s WiFi. Control calls to the fragrance diffuser device 385 can be made by a Web application programming interface (API) calls between the rideshare server 387 and the scent server 389. [0099] The power of scent personalizes the in-cabin experience can reduce stress and improves health and wellness of system users. Drivers and passengers can use computing devices having UIs to control the release of the right scent to create the right mood and driving experience. For example, the diffusion system can be used to stay alert and mindful, to relax and unwind on the long commute home, and/or to alleviate the nausea that comes with motion sickness. The inventive multi-scent dry-air diffuser can deliver the requested mood fragrance on demand to eliminate odors and promote wellness. As automotive ridesharing has become increasingly popular, shared mobility companies, including rideshare, are challenged with differentiating their service, maintaining and increasing per-ride revenue, improving passenger satisfaction, and promoting health and wellness. Odors which are difficult to hide, are often to blame for bad passenger experiences, as are motion sickness, bacteria and virus fears, and the lack of a pleasant scent. A bad experience can lead to bad driver or passenger reviews which can have a negative impact on the ride share business.

[00100] The described fragrance diffusers can also be used with autonomous fleets, combining the power of scent with biometric and malodor sensors, wellness ingredients, and built-in diffusion algorithms, shared mobility companies can create and ensure a fresh cabin environment for passengers that promotes wellness and well-being integrated malodor sensors detect odors that can automatically diffuse a dry-air malodor scent solution or send an alert or a control signal that the autonomous vehicle needs to go off-line for cleaning.

[00101] FIG. 32 is similar to FIG. 31 but in the illustrated configuration the driver’s computing device 383 phone is connected with the fragrance diffuser by WiFi communications. The car can have a bridge cellular / WiFi system which communicates with the driver’s mobile app running on the driver’s computing device 383 and the fragrance diffuser 385. The driver’s computing device 383 phone can be connected to the WiFi transceiver of the fragrance diffuser 385. Software can bridge all IP traffic to cellular communications except for the fragrance diffuser’s 385 WiFi communications traffic. The fragrance diffuser 385 can be connected to the internet through the phone’s 383 cellular communications bridge allowing the fragrance diffuser 385 to communicate with the scent server 389. Call to the fragrance diffuser 389 can be made by Web API between the rideshare server 387 and the scent server 389.

[00102] FIG. 33 is similar to FIGS. 31 and 32 but the driver’s computing device 383 phone is connected with the fragrance diffuser by WiFi direct. The driver’s computing device 383 phone is connected to the fragrance diffuser device 385 by WiFi Direct (Wifi P2P). The fragrance diffuser device 385 may not be directly connected to Scent platform server 389. The control calls to fragrance diffuser device 385 can be initiated by the ride share server 387 and sent through the wireless network to the driver’s app on the driver’s computing device 383. [00103] System users can setup and install the mobile fragrance diffuser into a vehicle with the following process. 1. The user can open the mobile fragrance diffuser to expose the empty cartridge slots in the body of the fragrance diffuser. 2. The user can insert the fragrance cartridges into the slots in the fragrance diffuser. 3. The user can close the mobile fragrance diffuser to secure the fragrance cartridges in the body of the fragrance diffuser. 4. A power and/or communications cable can be coupled to the port on the side of the fragrance diffuser. 5. The other end of the cable is coupled to the car’s USB port and the car can provide electrical power to the fragrance diffuser that can be used to charge a battery in the fragrance diffuser so that the fragrance diffuser can operate on battery power without the cable. Some cars have integrated wireless communication systems such as WiFi and/or cellular transceivers and the cable can be used for data communications with the transceiver(s).

[00104] As discussed, each cartridge can include identification information which identifies the fragrance so that the mobile digital aroma system can properly direct air to the selected target fragrance cartridge regardless of its position in the fragrance diffuser. As discussed, each fragrance cartridge can include a radio frequency identification (RFID) tag and the fragrance diffuser can include RFID readers. The RFID tags can transmit fragrance identification and a number of fragrance dispersions and a cartridge identification code. The RFID readers can read the information from the RFID tags on the fragrance cartridges and additional cartridge information, which can be used by the system. For example, the system displays the fragrance on a system output and directs air to the proper fragrance cartridge.

[00105] The cassette with fragrance cartridges can be used with various mobile digital aroma system assemblies. FIG. 34 illustrates a side view of an embodiment of a car 306 with an integrated digital fragrance system 121 and a user interface 122. The digital fragrance system

121 can be integrated within the dashboard area of the car 306. The user interface 122 can be an input device with a visual display output such as a touch screen or a visual display with input buttons. In other embodiments, the user interface 122 can be displayed on a mobile computing device such as a smartphone or tablet computer which is in wired or wireless communication with the digital fragrance system 121.

[00106] FIG. 35 illustrates a view of a user interface 122 which includes an input of the digital fragrance system. In an embodiment the user interface 122 can be displayed on a touch screen 124 which can communicate with the digital fragrance system. In this example, the user interface 122 can display inputs for nausea level and a passenger can press a button that corresponds to the current or anticipated nausea level. The user interface 122 can switch the visual display to ask the passenger’s nausea level periodically or in response to ride conditions such as winding roads which can result in nausea. The passenger can indicate the nausea level by pressing a corresponding nausea level button. The user interface 122 can transmit nausea signals to the digital fragrance system which can respond by emitting anti-nausea fragrances which can be proportional to the nausea level.

[00107] In the illustrated example, the user interface 122 can have nausea level inputs that range from: 0 to 5. However, in other embodiments, the nausea level can have any other range of levels. At nausea level 0 there are no symptoms 421 and at nausea level 1 the passenger can start yawning and have clammy palms and be lightheaded 423. At nausea level 2, the passenger can start burping, become lethargic and dizzy 425. At nausea level 3, the passenger can feel like the stomach is twisted or upset, the passenger can feel drowsy and start salivating 427. At nausea level 4, the passenger can be near vomiting and feel like the head is spinning, exhausted and disoriented 429. At nausea level 5, the passenger can start vomiting, feel like the head is tumbling and experiencing extreme sweating 431. In this example, if the user touched the nausea level 0, the digital fragrance system will maintain its current operation and not emit any anti-nausea fragrances.

[00108] In other embodiments, the user interface 122 can emit an audio output which asks the passenger what their nausea level is and the passengers’ response can be detected by a microphone which can detect a voice input from the passenger(s). The user interface 122 can periodically turn down any audio programs such as music and ask the passenger what their nausea level is. The passenger can indicate their nausea level and the user interface 122 can interpret the passenger’s voice and determine the passenger’s nausea level. The user interface

122 can transmit nausea signals to the digital fragrance system which can respond by emitting anti-nausea fragrances which can be proportional to the nausea level. [00109] The digital aroma system can have a UI input mechanism that can be used by passengers to input the motion sickness level. In an embodiment, UI can have a scale of 0-5. At level 0 the user feels nothing. At level 1 the user may be yawning, having clammy hands, and/or may be lightheaded. At level 2, the user may experience burping, lethargic feelings, and/or dizziness. At level 3, the user may experience twisted stomach aches, drowsiness, and/or salivation. At level 4, the user may vomit, feel head spinning, feel exhausted and/or disoriented. At level 5, the user has vomited, has head tumbling, and/or extreme sweating. The aroma system can perform experimentation by exposing motion sick users to anti-nausea particles which can be a proprietary formulation. The users can provide feedback through a UI which can allow the user to input the reduction or elimination of motion sickness.

[00110] The user can tell the system the nausea level with verbal inputs such as “level 2”, “level 5”, “emit maximum anti-nausea fragrance please!”, etc. The system can interpret the use’s audio inputs and the system can emit a corresponding fragrance. This system can be particularly useful for passengers who tend to get motion sick. The system may also emit audio signals which can help to comfort the system user. For example, the system may have default audio outputs based upon the user’s input nausea level. In an embodiment, the user can configure the system to output audio signals such as relaxing music or binaural tones Binaural beats therapy is an emerging form of soundwave therapy in which the right and left ears listen to two slightly different frequency tones yet perceive the tone as one. The binaural auditory beat that a person hears is the difference in frequency between the left and the right ear and should be at frequencies lower than 1,000 hertz (Hz) for the brain to detect the binaural beat. For example, if the left ear registers a tone at 200 Hz and the right at 210 Hz, the binaural beat heard is the difference between the two frequencies that can be about 10 Hz.

[00111] The volume of anti-nausea fragrance emitted by the system when nausea is likely to occur can be proportional to the intensity of the rotation or acceleration and the duration of the rotation or acceleration. For example, if the system detects a centripetal force of 0.05 - 0.1 G for a period of time between 30 seconds and one minute, the system can respond by emitting a level

1 volume of anti-nausea fragrance. If the system detects a centripetal force of 0.1 - 0.2 G for a period of time between one minute and two minutes, the system can respond by emitting a level

2 volume of anti-nausea fragrance. If the system detects a centripetal force of 0.2 - 0.3 G for a period of time between two minute and five minutes, the system can respond by emitting a level

3 volume of anti-nausea fragrance. The system can escalate the volume of anti-nausea fragrance with higher rotation or acceleration forces and the durations of the rotation or acceleration. [00112] Some studies have shown that humans are more susceptible specific frequencies of wave motion. For example, when test subjects were exposed to a series of different periods of up and down constant velocity motions including 0.2 seconds, 0.7 seconds 1.1 seconds and 1.6 seconds. The test results shows that short duration motions results in very little motion sickness. Motions that lasted 0.7 or 1.6 seconds resulted in more motion sickness and motions that lasted 1.1 seconds produced the most motion sickness in the test subjects. In an embodiment, the system can determine the frequencies of the motions that the user’s indicate motion sickness as described above. The system can then predict the likelihood of motion sickness based upon the detected and/or predicted frequencies of the traveling vehicle.

[00113] FIG. 36 illustrates a block diagram of possible components of a mobile digital aroma system which can include: an I/O 222, a trigger input 221, a sensor input 223, system monitor sensors 225, processor 227, a scent database 229, a system monitor sensor 225, a processor 227, a scent database 229, a system output 231, valve controllers 233, vales 237, fan/pump controllers 239 and fans/pumps 239. The I/O 219 can be a transceiver that allows communications between the mobile digital aroma system and other media devices, servers, smartphones, servers, other mobile digital aroma system and other computing devices. In an embodiment, the I/O 219 can provide system communications wirelessly through Blue Tooth, Wi-Fi, RFID or similar technologies with other devices, which can provide control signals for releasing fragrances. The trigger input 221 is an input for control signals from nausea input devices such as controllers, user interfaces, etc. In an embodiment, the trigger input 221 can provide system communications wirelessly through Blue Tooth, Wi-Fi, RFID or similar technologies with other devices, which can provide control signals for releasing fragrances. [00114] When the mobile digital aroma system is used, it can go through a startup procedure, which identifies each fragrance cartridge stored in the system. As discussed, the fragrance cartridges can have an identification system, which are read by the system monitor sensors 225. For example, in an embodiment each of the plurality of fragrance cartridges includes an RFID tag that identifies a scent of the dry fragrance cartridge and an RFID reader reads the RFID tags of the fragrance cartridges. The RFID readers can be system monitor sensors 225. The mobile digital aroma system includes a visual display, which can be a system output 231 for displaying the scent of the dry fragrance cartridge. The system can then match the different fragrance cartridges to the various fragrance triggers and store this information in the scent database 229. The system can emit the target fragrance when the corresponding trigger is detected by the trigger input 221 or other signals are detected by one of the sensor inputs 223. [00115] With reference to FIG. 36, the sensor input 223 can be a sensor that detects ambient signals such as a microphone that detects audio signal or a camera that can detect input signals. The system monitor sensor 225 can be coupled to the mobile digital aroma system components and detect the operation of the components. The scent database 229 can include a list of fragrances information, which can be used to match the fragrance based upon a fragrance identification code signal and then the identification with the valves 237 that must be open to actuate the release of the identified fragrance. The system output 231 can be a visual output, which can be used to inform the system user of system errors or cartridge replacement needs. The valve controllers 233 allow the processor 227 to control the operation of the valves 237. The fans/pumps controllers 235 can be used to allow the processor 227 to control the operation of the fans/pumps. The described mobile digital aroma system components can operate in conjunction to perform various functional actions that can be performed with software running on the processor 227.

[00116] In an embodiment, the sensor input 223 can be a camera and the processor 227 can run recognition software that receive video signals from the sensor input 223 camera and recognize objects and/or environments which may induce nausea such as winding roads or heavy traffic. In an embodiment there may be a known time delay between the actuation of the mobile digital aroma system to output a target fragrance and the user smelling the fragrance. The video object recognition system can identify the fragrance video object and/or environment trigger and identify the fragrance that is associated with the trigger. The mobile digital aroma system can then actuate the trigger associated fragrance delivery before the trigger object or environment is displayed by the known time delay period so that the fragrance is delivered to the viewer at the moment when the trigger object or environment is being displayed.

[00117] In an embodiment the mobile digital aroma system can use a microphone as a sensor input 223 that can be triggered the correct aroma with sound recognition software running on the processor 227 that recognizes audio commands and disperses the correct aroma based on the audio commands. The audio recognition system can receive the audio signals and use the scent database 229 to identify the fragrance associated with the audio signals. The processor 227 running audio recognition software can then control the valves 237 and/or fans/pumps 239 to actuate the fragrance delivery.

[00118] In an embodiment, the mobile digital aroma system can include software running on the local processor that can communicate through the I/O 219 to the Internet to a cloud service. This communication capability can be used with the system monitor sensor 225 for remote monitoring of the cassettes and fragrance cartridges, the duration of the number of uses, and remotely monitors the health of the pump and/or fan and health in the mobile digital aroma system to ensure the system components are working properly. If errors or end of life are detected in any of the system components, the processor 227 of the mobile digital aroma system sends alerts to a user or system administrator identifying the errors through the system output 231 when something is not working properly. The system output 231 can be a visual display, an audio output device and/or a digital wireless communication output.

[00119] Different vehicles can have different passenger accelerations when moving at the same velocity on the same road. For example, passengers in a bus or a van can be much higher than the passenger positions in a low riding sports car. The bus can have a soft suspension which causes the vehicle to rotate in roll as the bus travels around a turn. In order to accurately measure the passenger movements, the movement sensors can be mounted in the vehicle at the same or similar position as the passengers.

[00120] While the patent application describes the use of the inventive anti-nausea system as vehicles such as cars, buses, and vans which have wheels that travel over roads. However, this sensor system based nausea prediction system can used with any other type of non-road traveling vehicle such as trains, helicopters, airplanes, hovercrafts, hydrofoils, boats, ferries, etc. When the vehicle routes are known the system can predict possible nausea locations based upon a database of routes and known nausea locations. The system may also take into account weather conditions. For example, boats and airplanes will experience additional movements when these vehicles travel through storms and rough weather. In an embodiment, the system may obtain current and predicted weather and use this information to predict possible nausea locations and emit the anti-nausea fragrances to passengers as described.

[00121] The fragrance system can be configured to direct anti-nausea fragrance to specific passenger seats or equally (or unequally) distribute the anti-nausea fragrance to all vehicle passenger seats. In an embodiment, the system can detect the number and locations of the passengers with seat sensors which can detect the weight of the passengers on the seats. Based upon this information, the system can only direct the fragrances to the vehicle passengers to conserver the fragrances. For many trips, the only passenger is the driver and the system can only direct the fragrance towards the driver to conserve the fragrances. It is well known that people sitting in the back of the vehicle are more prone to getting motion sickness. In an embodiment, the system can asymmetrically distribute the anti-nausea fragrances based upon the seating positions with more fragrances being distributed to the back seats.

[00122] The fragrance sensors 308 can also be used to detect outside odors which can influence the user’s nausea. These outside odors can include: exhaust fumes, toxic gases (CO, carbon monoxide), body odor, vomit, flatulent, biomarkers, etc. The sensor system can respond by emitting fragrances and control the ventilation system to increase the air flow through the vehicle when offensive odors are detected.

[00123] The fragrance sensor input 223 can be based upon sensor mechanisms such as chemo sensors or by gas chromatography, which provides information about volatile organic compounds. Electronic fragrance sensors can include a detection system and a computing system. The detection system can consist of a sensor set, which can contact fragrance particles and react by producing a change of electrical properties. The fragrance sensor input 223 can be sensitive to all fragrance molecules but can be able to distinguish different fragrance particles. The fragrance sensor input 223 may use sensor arrays that react to volatile compounds on contact: the adsorption of volatile compounds on the sensor surface causes a physical change of the sensor. A specific response is recorded by the electronic interface transforming the signal into a digital value. Recorded data are then computed based on statistical models. In an embodiment, the fragrance sensor inputs 223 can be metal-oxide-semiconductor (MOSFET) devices - a transistor used for amplifying or switching electronic signals. Molecules can enter the fragrance sensor area and will be charged either positively or negatively, which should have a direct effect on the electric field inside the MOSFET. Thus, introducing each additional charged particle will directly affect the transistor in a unique way, producing a change in the MOSFET signal that can then be interpreted by pattern recognition computer systems.

[00124] The inventive fragrance system can be integrated or retrofitted into various vehicles. This can be an important feature for car rental companies and rideshare companies which can quickly and conveniently gain access to the fragrance system technology and devices to add scent diffusion systems into their fleets. The fragrances and anti-nausea can result in better customer experiences and also add revenue from every ride. For example, the preferred or desired scent and scent concentration or distribution can be part of a customer’s stored profile. [00125] When a rider orders a ride, the fragrance request can be received by the fragrance system of the driver’s car. When a driver picks up the customer, the fragrance system can immediately emit the preferred or requested scent or anti-nausea fragrance into vehicle. In different embodiments, the fragrance system can be implemented in various different ways. For example, the fragrance system hardware can be embedded in a console, the glovebox or built into a mobility diffuser which can be placed in a vehicle cupholder.

[00126] In the present mobile digital aroma system invention, the user can easily change the fragrance cartridges and may only need to replace the cartridges every few months depending upon the scent use. In an embodiment, the mobile digital aroma system can monitor the number of times each of the fragrance cartridges is used. When the life of the cartridge is reaching its end, the system can warn the user that the cartridge needs to be replaced. Thus, the cartridge only that needs to be replaced as needed. The longevity of each dry fragrance infused beaded cartridge is anywhere from 1,000 - 4,500 dispersions. In other embodiments, fragrance cartridges with larger chambers that hold more fragrance infused substrate materials can last longer and provide additional fragrance dispersions. The present mobile digital aroma system invention also addresses the issue of ease of replacement of the fragrance cartridges by the consumer. The mobile digital aroma system allows the swapping out of several fragrances simultaneously by removing and replacing the individual fragrance cartridges containing dry fragrance infused substrate materials.

[00127] In different embodiments, the described fragrance aroma dispersion system can be controlled and monitored by various different computer interfaces. For example, in an embodiment, an automotive interior can have integrated hardware components that emit multiple selected scents into the car’s interior. The driver or a passenger can select fragrances, which are automatically infused into the air system, which emits the scent throughout the car’s interior. The selectable fragrances can include an anti-nausea fragrance to personalize the driving experience. Any number of fragrances or combinations of fragrances can be selected. The fragrance cartridges can be easily replaced by the car dealer or by the consumer.

[00128] In an embodiment, the fragrance system can be a component of a connected control platform, which can include one or more digital aroma dispersion systems in communication with a system server that can monitor the operation of the systems. By monitoring the digital aroma dispersion systems, the control platform can perform intelligent inventory control for efficient fragrance cartridge efficiency. In an embodiment, the control platform monitors system usage by receiving fragrance cartridge usage information for each of the digital aroma dispersion systems. The system server can collect the operation and system usage data. By knowing the rated number of dispersions for each fragrance cartridge, the server can provide alerts to the individual system users for fragrance cartridges to replace individual cartridges. The warning messages can be transmitted to mobile smartphones or displays.

[00129] In some embodiments, the server monitoring system may even make suggestions for improving the efficiency of any of the installed systems. For example, a first fragrance cartridge may be used at an average rate of 10 dispersions per day and a second fragrance cartridge may be used at an average rate of 5 dispersions per day in a single system by a specific user the total dispersion rating is 3,000, then the server can predict that the first fragrance cartridge will last 300 days and the second fragrance cartridge may last 600 days. The server can transmit electronic warning signals to the system user when the fragrance cartridge has approximately 1 month or 30 days of remaining fragrance dispersions. Because these warnings are time based, they may not indicative of a specific number remaining fragrance dispersions. [00130] It can be inconvenient to replace single fragrance cartridges in a multi-cartridge system. In an embodiment, the server can determine that the user has a favorite fragrance that is used more often than the other fragrances based upon historical data and recommend to the user that multiple cartridges of the favorite fragrance be placed in the system. The system can then alternate dispersions between the two identical fragrance cartridges so that multiple fragrance cartridges can be depleted at the same or a similar rate and when fully depleted, the multiple fragrance cartridges can be replaced at the same time.

[00131] In an embodiment, the fragrance dispersion module can be installed in a vehicle with multiple fragrance cartridges. The fragrance dispersion module can receive control systems and transmit fragrance cartridge information to a smartphone and/or an in-dash mobile control unit. A driver or passenger of the vehicle can interact with their smartphones and/or an in-dash mobile control unit to control the operation of the fragrance dispersion module. The smartphones and/or an in-dash mobile control unit can communicate with other computing devices that are remote from the vehicle such as servers that receive information from many different fragrance dispersion modules, personal computers and mobile computing devices operated by the vehicle drivers or passengers, and other computing devices. These system components can share information so that the system functions optimally.

[00132] In an embodiment, the inventive system can perform various processes to detect and predict vehicle movements that will result in nausea. As discussed, when the user become nauseas when traveling in a vehicle, the user can press a button on a user interface to inform the system of the nausea condition. The system can respond by emitting the anti-nausea fragrance in a volume that is proportional to the nausea level input by the user through the user interface. In addition to emitting the anti-nausea fragrance, the system can also record the nausea information which can include: the location, the forces and movement of the vehicle prior to the user becoming nauseous. The system can also identify the rotation and forces that were detected by the movement sensors prior to the user’s nausea input and this information can be stored by the system in a nausea location database.

[00133] This information can be stored in a database for the individual users. Different people have different nausea susceptibilities. Some people get motion sick very easily while other people almost never suffer from motion sickness. Some people can be more sensitive than other people to certain odors and certain types of motions. In an embodiment, the system can cumulatively group the users into different categories of nausea susceptibilities. For example, as nausea data is collected, the system can identify users who frequently get nauseous, occasionally get nauseous, periodically get nauseous, rarely get nauseous and almost never get nauseous. These groups can be determined based upon nausea inputs per time. A passenger who gets nauseous several times per week or month will be in a more nausea susceptible group than a passenger who get motion sick once or twice a year. The system can compare the user’s nausea susceptibility based upon the magnitudes of motion and forces and durations detected prior to each user inputting a nausea level through the user interface. A user who can handle a higher rate of motion and forces and duration will be placed in a less nausea susceptible group than a person who gets nauseous with the same rate of motion and forces and duration. Each of these groups can have specific ranges of motions and road locations that are likely to result in nausea. The system users can each be given a nausea susceptibility rating and the nausea locations and intensity data can be shared with all system users.

[00134] As the system is used, the users will travel in vehicles and input road locations where nausea occurs. The system can receive the nausea locations and nausea intensities and this information can be stored in a database. The database can be used to create road nausea maps which can identify the detected road nausea areas. The different groups of users will have different nausea locations with more sensitive people having many more nausea locations than less motion sickness sensitive people. Thus, a nausea map for a more sensitive group will have more predicted nausea locations than the nausea map for a less sensitive group of system users. The nausea maps can be shared with other system users who are in the same sensitivity group. [00135] There will be overlap of nausea conditions with the different groups. For example, the conditions and locations that cause users who almost never get nauseous to be nauseous will be applicable to all other groups. The conditions and locations that cause users who rarely get nauseous to be nauseous will be applicable to all more susceptible groups. In an embodiment, the system can identify the passengers in a vehicle and the nausea susceptibility levels for each of the passengers based upon the stored nausea history. This nausea group database information can be used by the system for future trips. When the vehicle or user with a portable fragrance system travels, the system can look up the nausea map that covers the vehicle’s location for the group of passengers in the vehicle. The system can identify the locations had been a nausea location for the user and other users in the same nausea group.

Based upon this information, the system may emit an anti-nausea fragrance as the vehicle travels over a road that is likely nausea inducing road location based upon prior user nausea data or detected forces applied to the passengers including: rotation, acceleration, and duration that exceed predetermined threshold values for the nausea group.

[00136] In an embodiment, the system can store a nausea value for all nausea locations on a map and adjust the volume of the anti-nausea fragrance based upon the nausea value and the nausea susceptibility of the vehicle passengers. For example, the system can have nausea values between 1 and 100. These nausea values can be broken up into 5 groups: level 1 can be 1 - 20, level 2 can be 21 - 40, level 3 can be 41 -60, level 4 can be 61 - 80 and level 5 can be 81 - 100+. The 5 different levels can correspond to different volumes and/or durations of the anti-nausea fragrance. In a linear example, a level 1 nausea location can cause the vehicle to emit 1 second duration of the anti-nausea fragrance, a level 2 nausea location can cause the vehicle to emit 2 second duration, etc.

[00137] The volumes and or durations of the anti-nausea fragrance can also be adjusted based upon the nausea susceptibility of the vehicle passengers. In an embodiment, the volumes and/or durations of the anti-nausea fragrance can be based upon most nausea susceptible passengers. In order to prevent or minimize the emission of the anti- nausea fragrance, the system can adjust the fragrance emissions when lower nausea susceptibility passengers are in the vehicle. In an embodiment, the system can categorize all passengers into different nausea susceptibility classes. A class 1 passenger may easy be nauseas while a class 5 passenger may very rarely be nauseas due to road conditions. The system may divide the duration or volume of the anti-nausea fragrance output by the class level of the passengers. If a vehicle has at least one class 1 passenger, the full volume or duration of the anti-nausea fragrance can be output by the system. However, if the most nausea susceptible passenger is a class 3 passenger, the volume or duration of the anti-nausea fragrance can be divided by 3. if the most nausea susceptible passenger is a class 5 passenger, the volume or duration of the anti-nausea fragrance can be divided by 5. In an embodiment, testing can be performed and based upon the feedback of the passengers, the system can be properly adjusted to emit a sufficient volume of the anti-nausea fragrance for all varieties of passengers.

[00138] While passengers may normally have the same nausea group association over time. However, there can be situations where the passenger has an increased susceptibility to motion sickness. For example, the passenger may have a medical condition which temporarily alters the nausea susceptibility. These conditions can include: illness, hang over, headache, etc. In an embodiment, the system can allow users to make manual adjustments to their associated nausea group. If a user knows that he or she is feeling more susceptible to nausea, the user interface can be actuated to temporarily adjust the user’s associated nausea group.

[00139] A specific section of a road can have different nausea probabilities based upon different traffic conditions. In heavy traffic the vehicles may be traveling in a start/stop manner with increased concentration of exhaust fumes which can increase the likelihood of nausea. As traffic decreases, the vehicles can assume a steadier velocity and the exhaust fume concentration can decrease and the likelihood of nausea can decrease. In light traffic, the velocity of the vehicles can increase and the likelihood of nausea can decrease for straight roads. However, as the vehicle speed increases on windy roads, the centripetal forces applied to the vehicle passengers can increase which can result in increase the likelihood of nausea. In an embodiment, traffic speed can be detected based upon existing real time traffic maps and databases. [00140] This movement data can be used to identify and predict future conditions that can result in nausea. The system can include sensors such as accelerometers and gyroscopes that can detect the rotation and acceleration movements of the vehicle and user and the duration of the motions in real time. The system can identify rotations and forces that are equal to or greater than the rotations and forces that resulted in nausea. If the detected motion exceeds a predetermined motion threshold for greater than a predetermined duration, the system can calculate and determine a volume of anti-nausea fragrance to emit. The system can also identify the nausea locations that were stored in the database by the user and/or other system users. If the detected movement or the prior nausea location are detected with the matching vehicle speed, the system can also determine the volume of anti nausea fragrance to emit. The system can then output the anti-nausea fragrance in a volume that corresponds to the predicted nausea level.

[00141] Many people use GPS devices to determine driving routes to a destination. In an embodiment, the fragrance system can analyze the route and determine if there are any known or predicted nausea locations. In order to detect the rotation, the system can simply identify the curves and normal vehicle speeds on the route. The centripetal forces can be calculated by dividing the square of the velocity by the radius of the road curvatures, F_centripitai = V²/r. Road curves are frequently in groups which can increase the likely hood of nausea. The system can calculate the potentially problematic roads by determining that the centripetal force above the threshold level is repeated for at least a specific duration of time. In an embodiment, the inventive system can be used to provide route predictive nausea services. The user can input a destination. The GPS system can respond by determining a route to the destination. The system determines locations on the route where the vehicle motion will exceed a predetermine motion threshold for greater than a predetermined duration and the system also determine prior nausea locations for the specific user or uses who have similar nausea reactions.

[00142] The system can then analyze possible routes and identify the locations that may result in nausea based upon the passengers’ nausea group, known nausea location, and predicted vehicle motions based upon the passenger nausea susceptibility, road speed and curvatures of the route. The system can list possible routes with information and likelihood of nausea. The system may suggest a route which may be longer but less likely to result in motion sickness if a route that is less likely to result in motion sick if available. The system can issue an option to select the less nauseous route and the user can select the desired route. The system can also inform the user of the predicted time when the desired route has the optimum traffic level to minimize the likelihood of nausea for the passenger nausea group. The system can then determine the volumes of the anti-nausea fragrances. As the vehicle travels through the known route, the system can emit the predetermined volumes of the anti-nausea fragrances at the locations of predicted nausea or actual nausea.

[00143] In the present mobile digital aroma system invention, the user can easily change the fragrance cartridges and may only need to replace the cartridges every few months depending upon the scent use. In an embodiment, the mobile digital aroma system can monitor the number of times each of the fragrance cartridges is used. When the life of the cartridge is reaching its end, the system can warn the user that the cartridge needs to be replaced. Thus, the cartridge only that needs to be replaced as needed. The longevity of each dry fragrance infused beaded cartridge is anywhere from 1,000 - 4,500 dispersions. In other embodiments, fragrance cartridges with larger chambers that hold more fragrance infused substrate materials can last longer and provide additional fragrance dispersions.

[00144] The fragrance system used with the sensory experience network system can be used for specific purposes. As discussed, when the system predicts or received a manual input of motion sickness, the system can emit the anti-nausea fragrance and provide audio output and lighting which can each help to mitigate the nausea. The user interface of the integrated mobile control and/or smartphone may have “nausea” input buttons that can result in the emission of the anti-nausea fragrance that can reduce nausea for a driver or passenger who is not feeling well or is carsick. For example, fragrances like peppermint, ginger, lavender, chamomile, cardamom, coriander, fennel, nutmeg, aniseed, star anise, bergamot, lemon, spearmint, grapefruit and geranium can help reduce nausea. If the nausea symptoms persist or escalate, the driver can be instructed to slow down or take an alternative route which has fewer curves. In extreme situations such as a discomfort level 4 or 5, the driver can be instructed to pull off of the road and stop. Similarly, if the vehicle is an autonomously driven vehicle, the vehicle control system can be instructed to slow down, take an alternative route which has fewer curves or pull off of the road to stop in extreme situations.
