     BACKGROUND 
     Motion sickness is a common problem with transportation vehicles such as cars, buses, planes, boats, and trains. Symptoms include fatigue, uneasiness, dizziness, and vomiting. Typical actions that can reduce the symptoms of motion sickness include focusing the eyes on objects straight ahead of the person as well as wrist bands, oral and transdermal medications that can reduce these symptoms. 
     Various studies show that there is a large percentage of adults will experience car sickness in autonomous cars because the passengers will be multi-tasking while riding in these vehicles. http://umich.edu/˜driving/publications/Motion-Sickness--Report-061616pg-sent.pdf What is needed is an improved fragrance system which can predict and mitigate the symptoms of motion sickness, which can also be integrated into the vehicle or stand alone and does not use scented oils and is not carcinogenic. 
     SUMMARY OF THE INVENTION 
     Motion sickness may be caused by conflicting signals in the inner ear, eyes, and sensory receptors. Motion is sensed by the brain through different pathways of the nervous system including the inner ear, the eyes, and the tissues of the body surface. The present invention is directed to a digital aroma system that provides aroma experiences that can be utilized in vehicles to predict or respond to motion sickness with one or more fragrances which can reduce the symptoms of motion sickness. The inventive anti-nausea fragrance system can be used with any type of moving vehicle including: cars, vans, buses, off-road vehicles, trains, helicopters, airplanes, hovercrafts, hydrofoils, boats, ferries, etc. 
     The present invention is a digital aroma system that utilizes dry fragrance infused beads or other solid substrate that contain porous fragrance materials contained in a fragrance cartridge(s) that is removable mounted in an interchangeable cassette system that that connects to a manifold. The manifold has specific airway passages that are connected to fans or pumps that are controlled by a computer processor. In response to a fragrance control signal or a fragrance trigger, the processor can selectively direct air into the any individual target fragrance cartridge. More specifically the processor can cause the fan or pump to pull or push fresh unscented air through the target fragrance cartridge and the fresh air passes by the particles infused with a dry fragrance material. The aroma reaches the individual through one or several outlets. 
     The invention digital aroma system is designed to fit into a very small footprint while providing many aromas that enhance the user&#39;s ride experience in the vehicle. In an embodiment the digital aroma system can simultaneously hold numerous (for example six) distinct fragrance cartridges. The digital aroma system can be coupled to or integrated into a vehicle or alternatively, the digital aroma system can be incorporated into a separate device such as a system that clips on the headrest posts, or a headset, an apparatus worn around the neck or a handheld device. 
     The digital aroma system invention can include a processor that runs computer software that detects vehicle and user movements that may result in motion sickness and creates an anti-nausea smell sensory experience. This computer processor of the digital aroma system can also communicate with remote computers in a cloud-based system and/or a remote server. In an embodiment, the digital aroma system can communicate wirelessly through Blue Tooth, Wi-Fi, RFID or similar technologies with other devices, which can provide control signals or triggers for releasing fragrances. 
     The digital aroma system can include a processor that can control and monitor the operation of the system components. The processor can be coupled to fans and/or valves to selectively direct air to the target fragrance cartridge. When a desired fragrance signal or trigger is detected, the processor can direct fresh air through the air inlet to the target fragrance cartridge. The dry fragrance can mix with the fresh air and be directed to a scent outlet to the system user. In some embodiments, the processor can direct fresh air through two or more target fragrance cartridges to provide a mixed fragrance to the user. The scent is provided as a limited predetermined period of time or volume of air. Once the scent is provided to the user, the processor can the stop the flow of air through the fragrance cartridge by stopping a fan(s) or closing a valve(s). In an embodiment, the processor can be programmed to flush the scent outlet of the manifold periodically with fresh air so that subsequent fragrances are not mixed or contaminated. For example, the processor may direct fresh air through the scent outlet after each fragrance output by the system. 
     The digital aroma system can release fragrances based upon control signals or triggers. The digital aroma system can include a receiver, which receives fragrance signals. In response to the fragrance signals, the processor can identify the corresponding target fragrance cartridge and direct air to the target fragrance cartridge, which can result in the dry fragrance device delivering a dry fragrance aroma to the user. 
     In some embodiments, the digital aroma system can respond to manual inputs. For example, in an embodiment the digital aroma system can have an input which can allow the user to input a level which can range from 1-5 in motion sickness discomfort. The discomfort levels can be: 0 No symptoms, 1 Yawning, Clammy, Lightheaded, 2 Burping, Lethargic, Dizzy, 3 Twisted or upset Stomach, Drowsy, Salivating, 4 Near Vomit, Head Spinning, Exhausted, Disoriented, 5 Vomiting, Head tumbling, Extreme sweating. The user can input the motion sickness discomfort level and the digital aroma system can respond by emitting an anti-nausea fragrance which can vary in volume and fragrance based upon the discomfort level. For example, when the user inputs a discomfort level of 0, the system can emit normal fragrances desired by the user which may not have any anti-nausea properties. In an embodiment, the anti-nausea fragrance is a proprietary blend of dry of at least 2 of the following scents: Peppermint, Spearmint, Lemon, Ginger, and Lavender. The percentages of each scent of the proprietary blend varies on the combination and does not always include all of these ingredients. 
     When the user inputs a discomfort level of 1, the system can output a small volume of a first anti-nausea fragrance and if the user inputs higher discomfort levels the system can output higher volumes of the first anti-nausea fragrance. In another embodiment, the system can change the anti-nausea fragrance based upon the user input higher discomfort level. When a user inputs a level 1 discomfort level, the system can emit a first anti-nausea fragrance, when the inputs a level 2 discomfort level, the system can emit a second anti-nausea fragrance, when the inputs a level 3 discomfort level, the system can emit a third anti-nausea fragrance, etc. 
     In an embodiment, the user input can be through wireless communications with a mobile application running on a smart phone. The input can be an electro-mechanical input such as a touch screen input, an audio input such as a microphone, The digital aroma system can provide a feed-back loop. The system can analyze and record the inputs of the user including bio-metric inputs, and the movements of the vehicle with sensors such as accelerometers and gyroscopes. Based upon this information the system can learn the personal preferences of the user based on their feedback experience. The data from the user&#39;s discomfort level as well as the vehicle&#39;s route mapping and acceleration, deceleration, and G-force can be used by an Artificial Intelligence (AI) predictive system to predict the movements of the vehicle and the discomfort level of the system users. 
     In some embodiments, the digital aroma system can respond automated triggers. Such as rolling, acceleration, ambient odor, etc. For example, the system may interact with movement or motion sensors to detect and predict vehicle movements. The system can then disperses specific motion sickness reducing scent based on acceleration, deceleration, and G-force in curves. Interacts with google maps or any other mapping system and predicts g-force based on the speed of the vehicle and curves of the road. This will automate the dispersion process using AI to effectively predict motion sickness based on the route mapped, speed and timing of when the event will occur. This will then diffuse the motion scent just prior to the G-force effect. Therefore pre-empting the motion sickness all together. Scents that can reduce motion sickness can include proprietary blends of Peppermint, Spearmint, Lemon, Ginger and Lavender.

     An embodiment of a fragrance cartridge is illustrated in  FIGS. 1-4 .  FIG. 1  illustrates a bottom view of an embodiment of the fragrance cartridge  101  with a plurality of airflow slots  103  in the bottom surface  105 . In an embodiment tabs  108  can be mounted on the outer surface of the cartridge  101  which are used to secure the cartridge to a cassette.  FIG. 2  illustrates a perspective view of the fragrance cartridge  101  in a disassembled state. In this embodiment the fragrance cartridge  101  includes an upper housing  107  structure which has an internal volume and a lower housing  109  structure which has a lower surface  105  and a center divider  106  having air flow slots  103 . The center divider  106  can have an outer surface which fits within a groove  110  formed in the internal surface of the upper housing  107 .  FIG. 3  illustrates a side view of a fragrance cartridge  101  that has a two piece housing that includes an upper housing  107  and a lower housing  109  that are secured together to form the complete housing for the fragrance cartridge  101 .  FIG. 4  illustrates a perspective view of the fragrance cartridge  101  in a disassembled state. The upper housing  107  can be filled with a plurality of substrates  113  that are infused with a dry fragrance. In an embodiment the substrates  113  can be spherical balls or other three-dimensional objects such as cubes, cylinders, particles or other geometric volumes before the outer diameter of the bottom surface  105  structure can be fused or coupled to the inner diameter of the bottom of the upper housing  107  structure. 
     While the fragrance cartridge  101  is illustrated as a dome shape with slots  103  in the lower surface  105  and the lower surface  109 , in other embodiments the fragrance cartridge can have any other geometric shape that can hold the plurality of substrates  113 . The width of the substrates  113  is wider than the slots  103  in the lower surface  105  and a center divider  106 . When air flows through the cartridge  101 , the dry fragrance can mix with the air and be removed from the substrates  113  resulting in scented air exiting the cartridge  101 . In an embodiment, the lower portion of the fragrance cartridge  101  can have a cylindrical shape that can be placed into a corresponding cylindrical bore in a manifold or cassette matrix. 
     In an embodiment with reference to  FIGS. 5-8  an embodiment of a fragrance cassette matrix  115  is illustrated. The illustrated embodiment of the cassette matrix  115  can have five cartridge sockets  117  formed in the upper surface that securely hold five fragrance cartridges  101  in a single row configuration. In other embodiments, the cassette matrix can hold more fragrance cartridges  101  in different configurations such as a 2×6, 3×8 or any other one or two or three dimensional array configuration including circular cassette matrix configuration. 
     Each of the cartridge sockets  117  has two air channels, one inlet  114  and one outlet  116  and can be keyed with tab slots  119  so that fragrance cartridges  101  can be easily placed in and removed from the sockets  117 .  FIG. 5  illustrates a top view of a fragrance cassette matrix  115 .  FIG. 6  illustrates a perspective top view of the cassette matrix  115 . The cassette matrix  115  can have cartridge openings  117  that each holds a fragrance cartridge.  FIG. 7  illustrates a side view of the cassette matrix  115 . The cassette matrix  115  can have inlet holes formed on one side of the cassette matrix  115  and outlet holes  122  formed on the opposite side of the cassette matrix  115 . The inlet holes can be coupled to the inlet holes  114  and the outlet holes  122  can be coupled to the outlets  116 . 
     The cylindrical cartridge openings  117  can be aligned with the lower cylindrical cartridge and the tab slots  119  can be aligned with the tabs on the side of the lower cylindrical cartridge. The tab slots  119  can be vertical slots extend down the sides of the cartridge openings  117 . The tab slots  119  can intersect circular slots  120  which extend around a lower inner diameter portion of the cartridge openings  117 . Once the fragrance cartridge is fully inserted into the cartridge socket  117 , the fragrance cartridge can be axially rotated within the socket  117  so that the tabs are in the circular slots  120  and are no longer aligned with the tab slots  119 . By offsetting the tabs from the tab slots  119 , the fragrance cartridge can be secured within the cassette matrix  115 . The tab and tab slots  119  can provide a mechanism for securing the fragrance cartridges to the cartridge sockets  117 . When the fragrance cartridge is placed in the cartridge socket  117 , the cartridge tabs can be placed in the tab slots  119 . 
       FIG. 8  illustrates a perspective top view of the cassette matrix  115  with the fragrance cartridges  101  positioned in the cartridge sockets  117 . In the illustrated embodiment, the cartridges  101  have been inserted into the cartridge sockets  117  with the tabs aligned with the tab slots and then rotated 90 degrees after being fully inserted.  FIG. 9  illustrates a perspective side view of the cassette matrix  115  and with the cartridges  101  positioned over the socket openings  117 . When the cartridges  101  are inserted into the socket openings  117  the tabs  108  are aligned with the tab slots  119 . The cartridges  101  are interchangeable within the cassette matrix  115 . In the fully inserted position, the inlet holes  114  and the outlet holes  116  at the bottom of each cartridge socket  117  are adjacent to the slots ( 103   FIG. 1 ) formed with the bottom of the cartridge with the center divider ( 106   FIG. 2 ) between the inlet holes  114  and the outlet holes  116 . 
     As discussed each cartridge  101  can include identification information which identifies the fragrance so that the digital aroma system can properly direct air to the target fragrance cartridge  101  regardless of its position in the cassette matrix. For example, in an embodiment, each fragrance cartridge  101  can include a radio frequency identification (RFID) tag  241  and the cassette matrix  115  can include RFID readers. The RFID tag  241  can transmit fragrance identification and a number of fragrance dispersions and a cartridge identification code. The RFID reader  243  can read the identification information from the RFID tag  241  on the fragrance cartridge  101  and additional cartridge information, which can be used by the system. For example, the system displays the fragrance on a system output and direct the air to the proper fragrance cartridge  101 . 
     The cassette with fragrance cartridges can be used with various digital aroma system assemblies.  FIG. 10  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 smart phone or tablet computer which is in wired or wireless communication with the digital fragrance system  121 . 
       FIG. 11  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&#39;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. 
     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. 
     In other embodiments, the user interface  122  can emit an audio output which asks the passenger what their nausea level is and the passengers&#39; response can be detected by a microphone which can detect an 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&#39;s voice and determine the passenger&#39;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. 
       FIG. 12  illustrates an embodiment of the digital aroma system  123  used with vehicle that shows the airflow paths through the system components. The cassette  115  with the fragrance cartridges  101  can be mounted adjacent to the air inlet  125 . The fragrance cartridges  101  can each be filled with substrates  113  which are infused with dry fragrances. Micro fans  131  that are individually controlled can be mounted in the digital aroma system  123  adjacent to the cassette  115 . The micro fans  131  can be coupled to a processor that selectively actuates the micro fans  131  and directs scented air into a manifold  133  which can include a separate air flow path or channel for each fragrance cartridge  115 . By having separate air flow paths for each fragrance cartridge in the manifold  133 , there is no contamination and/or mixing of the different scents from the fragrance cartridges  101 . The scented air exits the air outlet  129  and is directed towards the user holder of the controller  121 . In this configuration, the micro fans  131  create a low gas pressure, which pulls air through the fragrance cartridges  101 . In an embodiment, the micro fans  131  can be placed at the scented air outlet  129  so that the manifold  133  is between the cassette and micro fans  131 . In other embodiments the micro fans can be positioned before the cassettes to create higher gas pressure that push air through the fragrance cartridges  101 . Thus, the micro fans  131  can be placed in various different positions that creates a vacuum and sucks the air through the cartridges  101  and then pushes the air through the manifold. In different embodiments the fans  131  can be replaced by micro pumps 
       FIG. 13  illustrates a view of an embodiment of an interior surface  121  of a vehicle with an integrated digital aroma system  123  that includes a cassette slot  127  and micro fans  131 . To use the digital aroma system  123  the cassette  113  filled with fragrance cartridges  101  can be inserted into the cassette slot  127 . The fans  131  are placed forward of the cassette  113  and the manifold. When the digital aroma system  123  is actuated to release a scent, one (or more) of the fans  131  is actuated that creates high pressure that pushes air through the cartridge  101  containing the designated fragrance. The airflow generated by the fans  131  blows scented air through the manifold towards the user of the controller  121 . 
       FIG. 14  illustrates a view of another embodiment of an interior surface  121  of a vehicle. In this embodiment, the micro fans  131  are mounted in a downstream position relative to the cassette slot  127 . In this configuration, the cassette slot  127  can be adjacent to the air inlet  125 . When the digital aroma system  123  is actuated to release a scent, one of the fans  131  is actuated creating a vacuum that pulls air through the cartridge  101  containing the designated fragrance to blow scented air through the manifold towards the user of the controller  121 . 
     In an embodiment, the anti-nausea digital aroma system can be used as a separate unit worn by a passenger riding in a vehicle.  FIG. 15  illustrates a headset  135  that includes an integrated digital aroma system  123 . In this embodiment headset  135  that includes ear cups  137  which can include speakers that emit sound and a mouthpiece  143  that includes a microphone that is used for receiving voice commands. In the illustrated configuration, most of the digital aroma system  145  components including the cassette with a replaceable anti-nausea fragrance cartridge, fans and check valves can be mounted in one of the ear cups  137 . An air passageway  139  can be built into an arm, which extends from the ear cup  137  to the mouth. When the digital aroma system  145  is actuated to release a scent, one of the fans is actuated that directs air through the fragrance cartridge and blows the scented air through the air passageway towards the nose of the user wearing the headset  135 . In an embodiment, 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&#39;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&#39;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—10 Hz. 
     Details of the configuration of an embodiment of the digital aroma system  145  used with the headset system are shown in  FIG. 16 . In this embodiment, the digital aroma system  145  can include fragrance cartridges  101  which can be individually placed into cartridge holes  147  around the outer surface of the ear cups of the headset with the inlet sides of the cartridges  101  exposed to ambient air. Thus, in this embodiment the digital aroma system  145  may not include a cassette. The user can easily access and exchange each of the individual fragrance cartridges  101 . Air passageways  139  can connect each of the fragrance cartridges  101  to a corresponding fan  131  which can blow the scented air from the outer edge of the ear cup  137  into an inner circle  149  and then through an air passageway  139  to the nozzle outlet  141 . When a fragrance is to be delivered to a user, a micro fan  131  is actuated which draws air into the interior volume  153  of an ear cup  137  of the headset  135 . This air movement pulls fresh ambient air through the fragrance cartridge  101 . The scented air is then directed through the air passageway  139  and out an outlet nozzle adjacent to the face of the headset wearer. Also located with the within the passageways of the digital aroma system  145  are small check valves  151  that prevent the back flow of scented air into the other fragrance pathways and keeps the fragrance cartridges  101  and fragrance infused substrates pure and discreet from fragrance contamination. 
     In other embodiments, the digital fragrance system can be attached to various other portable computing devices such as tablet and smart phones.  FIG. 17  illustrates a side view of a digital aroma system  155  attached to a back surface of a tablet computer  157  and  FIG. 18  illustrates a side view of a digital aroma system  155  attached to a back surface of a smartphone computer  159 . In this embodiment, the digital fragrance system can also be independent of the vehicle. The mobile computing device can have integrated input such as a microphone and touch screen. In a basic form of operation, the system can run a mobile application that respond to user inputs and emit a volume of an anti-nausea fragrance that is proportional to the nausea level. The mobile computing device can have motion sensors such as accelerometers, gyroscopes, GPS, maps, cameras, etc. which can interact with the mobile application to predict possible nausea conditions such as high-speed rotation, high centripetal forces, windy roads, traffic, acceleration/deceleration forces etc. The mobile application can detect rotation and/or centripetal forces above a predetermined level and the duration of the rotation or centripetal forces and respond by emitting the anti-nausea. 
     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 an 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 an 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 an 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. 
     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&#39;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. 
     The digital aroma system  155  can include interchangeable fragrance cartridges that are removably attached to a cassette and a manifold that can include fans or pumps and check valves. The digital aroma system  155  can be configured to direct scented air to an air outlet adjacent to the bottom edge of the tablet computer  157  or smart phone  159 . However, tablet computers  157  and smart phones  159  can detect the orientation of the screen with accelerometers and adjust the displayed images so that they are always upright. In some embodiments, the digital aroma system  155  can adjust the air output to always be at emitting scented air from the bottom edge of the computing device regardless of the orientation of the digital aroma system  155 . In an embodiment the digital aroma system  155  may include fans that normally pull the fresh air through the fragrance cartridges and out the bottom edge of the tablet computer  157 . However, the digital aroma system  155  can also detect when the tablet computer  157  or smart phone  159  has been turned upside down. When this orientation change is detected, the fans can be controlled to operate in reverse the airflow to push fresh air from the new top through to the new bottom of the table computer  157 . 
     In different embodiments, the fragrance cartridges used with the digital aroma system can be configured with an air inlet and a scented air outlet on the same side of the fragrance cartridge. With reference to  FIG. 19  is a top cross section view of a generally cube shaped housing  163  embodiment of a fragrance cartridge  162 , which is at least partially filled with fragrance infused substrates  113 . The fragrance cartridge  162  includes divider  167  that extends across a center the width of the housing  163 .  FIG. 20  illustrates a top cross section view of the bullet shaped housing  164  embodiment of a fragrance cartridge  162  which has a lower cylindrical portion and an upper hemispherical portion. The fragrance cartridge  162  can have a divider  167  that extends across the width of the housing  163 . 
       FIG. 21  illustrates a side cross section view of the generally cube shaped housing  163  embodiment of a fragrance cartridge  162  with arrows illustrating the flow path of air through air inlet holes in the lower surface  105  of the housing  163  where the air mixes with the dry fragrance substrates  113 . Fragrance particles mix with the air and travel upward and through small holes in the upper portion of the divider  167  which can be planar and rectangular in shape. The fragrance substrates  113  can be larger than the openings in the divider  167  so that the fragrance substrates  113  will not travel from the inlet side of the fragrance cartridge  162  to the outlet side of the fragrance cartridge  162 . The air then travels back down on the opposite side of the fragrance cartridge  162  and out through air outlet holes in the lower surface  105  of the housing  163 . 
     In the embodiment shown in  FIG. 22 , the fragrance cartridge  164  can have a bullet shaped housing with a lower cylindrical shaped housing and an upper half spherical shaped housing. The divider  167  is positioned against the lower surface of the housing  165  and provides a passageway above the divider  167 . The arrows illustrating the flow path of air through air inlet holes in the bottom of the lower surface  105 , the air mixes with the fragrance substrates  113  and travels up one side the divider and through slots in the upper portion of the divider  167 . The air then travels down the opposite side of the fragrance cartridge  164  mixing with the fragrance substrates  113  and travels back through air outlet holes in the in the lower surface  105  of the housing  164 . 
     The fragrance from the substrates  113  that is mixed with the fresh air and emitted by the fragrance system can include different fragrance components including: top notes, middle notes and base notes. Top notes can contain the smallest fragrance molecules, which can quickly dissipate. Middle notes can contain medium sized fragrance molecules that can last longer than the top notes and may dissipate slower than the top note molecules. Base notes can dissipate the slowest and can contain larger fragrance molecules that can last for longer than the middle notes. Base fragrance molecules are larger than middle note fragrance molecules, which are larger than top note fragrance molecules. 
     As discussed, the fragrance cartridges  162  can have sealed housings that can contain dry fragrance beads and additional air space within the cartridge housing. Rather than completely filling the inner volume of the fragrance cartridges  162  with substrates  113 , these sealed cartridge designs have additional air space so that the base notes of the fragrance will infuse into the air molecules residing in the cartridges  162  before each diffusion so that the based notes will be deployed into the air when the airflow starts. Because of the larger mass of the base note fragrance molecules compared to the top and middle note molecules, base note fragrance molecules require more time to be infused into the air inside the cartridges  162 . If the cartridges  162  are completely filled with dry fragrance bead substrates  113 , then the base note fragrance molecules s will not disperse properly into the cartridge airspace. The volume ratio of air space to dry fragrance beads for optimum base note fragrance molecule infusion can depend upon the type of fragrance. In an embodiment where the fragrance cartridges is a citrus scent, the bead to air ratio can be 75% or 70% to 80% of the volume and the remaining volume occupied by air space. In contrast a denser or heavier fragrance such as tobacco may only require up to 25% or 20% to 30% dry fragrance beads substrates  113  by volume and the remaining volume of air. These dry fragrance bead to air volume ratios can be required to ensure the proper deployment of based note fragrance molecules such as a tobacco scent infusion of the air in the cartridges  162  before the scented air flow is transmitted through the cartridges  162 . 
     Because the cartridges have air inlets and scented air outlets on the same lower surface, the cartridges can be mounted in a cassette that holds the cartridges against a manifold that has both air inlets and scented air outlet paths.  FIG. 23  illustrates a bottom perspective view of an embodiment of a cassette  169  that has openings  171  that hold the individual fragrance cartridges  162 . The fragrance cartridges  162  be inserted or replaced from the cassette  169 . As discussed above, the fresh unscented air inlet  173  and the scented air outlet  175  of the fragrance cartridge  162  can be on the same planar side surface of the cartridge  162 . Thus, the cassette  169  can be closed on all but one side since air does not flow through the cassette  169 . 
     With reference to  FIG. 24 , a perspective view of an embodiment of the cassette  169  and a manifold module  177  is illustrated. The cassette  169  is in the upright position, which shows the solid upper surface. The air inlet and scented air outlets of fragrance cartridges are exposed on the lower surface of the cassette  169 . The manifold module  177  can have a recess  183  that corresponds with the outer perimeter of the cassette  169 . The manifold module  177  can also have internal air passageways that are connected to the fragrance cartridges. In this embodiment, the manifold module has a row of fresh air outlet holes  179  and a row of scented air inlet holes  181 . The cassette  169  can be placed in the recess  183  and held against the manifold module  177  with a releasable coupling mechanism. A gas seal such as an airtight gasket can be placed between the fragrance cartridges and the manifold module  177  to separate the different fragrance cartridges and seal the fresh air outlet holes  179  and air inlet holes  181 . The side surfaces of the manifold module  177  can have side holes  185 , which can be connected to the internal passageways within the manifold modules  177  and the fresh air outlet holes  179  and air inlet holes  181 . 
     With reference to  FIG. 25 , an exploded view of a different embodiment of a manifold module  177  and cassette assembly is illustrated. In this embodiment, the assembly can include a cassette chamber  199  that surrounds a plurality of fragrance cartridges  201 . Different fragrance infused substrates can be placed in each of the fragrance cartridges  201  that are within the cassette chamber  199 . A cassette gasket seal  197  can be placed between the cassette chamber  199  and the manifold module  177  to prevent air from flowing between the different fragrance cartridges  201  or out the top and sides of the cassette chamber  199 . The cassette assembly including the cassette chamber  199  and fragrance cartridges  201  are held to the manifold module  177  with locking pins  207  that extend through the cassette assembly components. The locking pins  207  can have threaded ends which can be rotated and tightened into the manifold module  177  to compresses the gasket  197  between the cassette chamber  199  and the manifold module  177 , which creates an airtight assembly. When the adjacent manifold modules  177  are attached to each other, a manifold gasket  209  can be placed between the manifold modules  177  to create an airtight seals for the aligned and coupled side air holes. 
     With reference to  FIG. 26  a top view of an embodiment of a manifold module  177  which shows the internal passageways which include a length passageway  191  that is connected to the fresh air outlets  179  that extends along the length of the manifold module  177 . The internal passageways also include parallel width passageways  189  that extend across the width of the manifold module  177  where each of the width passageways  189  are coupled to a scented air inlet  181 . The length passageway  191  is offset vertically from the width passageways  189  so that they are not connected. The manifold module  177  can also include an inlet air passageway  215  that extends through the width of module  177  on one edge and an outlet scent passageway  217  that extends along the length of the module  177  on another edge. An inlet valves (not shown) can be coupled to the length passageway  191  and outlet valves can be coupled to the width passageways. When actuated to open the inlet valve can connect the length passageway  191  to the inlet air passageway  215  and the outlet valves can connect the width passageways to the outlet scent passageway  217 . When multiple modules  177  are connected, the inlet air passageways  215  can be connected to form a longer inlet air passageway that extends across the entire width of the assembly. In contrast, when multiple modules  177  are connected, the system may only use the outlet scent passageway  217  of the end module  177  with the outlet scent passageways  217  of the other modules  177  being unused. 
     With reference to  FIG. 27 , a digital aroma system  193  having multiple manifold cassettes  169  mounted on modules  177  can be coupled together with the side holes  185  aligned to form a larger digital fragrance system. By connecting and sealing the side holes  185  to the side holes  185  of the adjacent manifold module  177 , the digital fragrance system can be expanded to include any number of fragrance cartridges. In the illustrated example, there are six manifold modules  177  with each of the manifold modules  177  containing five fragrance cartridges. In this example, the illustrated digital aroma system assembly  193  can include a total of thirty fragrance cartridges. 
     With reference to  FIG. 28 , the digital aroma system  193  can have a plurality of inlet valves  211  can be coupled to the inlet air passageways on one end of each of the manifold modules  177 . A plurality of outlet valves  213  can be coupled to the outlet scent passageways on one of the end manifold modules  177  and the opposite ends of the outlet scent passageways can be sealed to prevent air from escaping. Air can be directed through the digital fragrance system to any individual fragrance cartridge by controlling the open/closed positions of the inlet valves  211  and the outlet valves  213 . The digital aroma system  193  formed from a plurality of manifold modules can have an array of internal passageways which can be coupled to fresh air inlets  179 , scented air outlets  181 , inlet valves  211  and outlet valves  213 . The inlet valves  211  and outlet valves  213  are opened and closed to control the scented air outlet path. By actuating (opening) one inlet valve  211  and one outlet valve  213  and keeping all other inlet valves  211  and outlet valves  213  closed, a passageway to a specific fragrance cartridge can be selected by the digital aroma system. 
       FIG. 29  illustrates a top view of a simplified embodiment of a digital aroma system  193  configured with nine fragrance cartridges spaces for clarity. Each cartridge space includes a fresh air inlet  179  and a scented air outlet  181 . In an embodiment pressurized air from a fan or pump can be applied to the inlet air passageway  215 . When one of the inlet valves  211  is actuated pressurized air can flow through the corresponding length passageway on a selected row of fragrance cartridges on a single cassette. When one of the outlet valves  213  is open, air can flow through the fragrance cartridges and scented air can flow to the outlet passageway  217 . From the simplified digital aroma system  193 , the scented air can be directed towards the nose of the system user. In an alternative embodiment a vacuum or low pressure from a fan or pump can be applied to the outlet scent passageway  217 . When one of the inlet valves  211  is open, air can be drawn or pulled through the corresponding length passageway on a manifold module  177 . Air can then flow through one of the fragrance cartridges to the outlet passageway  217  through the fan or pump and be directed towards the nose of the system user. The valves can be actuated by a valve controller(s) that is controlled by a system processor in response to a scent release signal or trigger. Each individual fragrance stored in the digital aroma system  193  can be output by actuating a combination of one inlet valve and/or one outlet valve. In some embodiments, it can be desirable to mix a plurality of fragrances, which can be performed by opening valves to a plurality of fragrance cartridges. 
       FIG. 30  illustrates a block diagram of possible components of a digital aroma system which can include: an I/O  219 , 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 digital aroma system and other media devices, servers, smartphones, servers, other 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. 
     When the 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 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 . 
     In an embodiment, the digital aroma system can disperse different fragrances in different ways because with each different scent, there is a specific way in which the scent interacts with the air and within the olfactory senses in a human. An example of this difference in scents can be illustrated by comparing citrus and tobacco type fragrances. Citrus type scent molecules travels faster than a tobacco type of fragrance through air. 
     Graham&#39;s Law can be used to compare the effusion rates of different odorous molecules such as lemon and tobacco. Graham&#39;s law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight. Under ideal conditions, you would smell lemon first because it is composed of ten carbon atoms, eighteen hydrogen atoms, and a single oxygen atom, which gives it a molar mass of 154.25 grams per mole. (A mole is a unit equivalent to about 6*10{circumflex over ( )}23 individual molecules). Tobacco, one the other hand, has nine carbon atoms, nine hydrogen atoms, and one nitrogen atom, which adds up to a molar mass of 131.17 grams per mole. Graham&#39;s Law says that the rate of lemon effusion divided by the rate of tobacco effusion will equal the square root of the molar mass of tobacco divided by the molar mass of lemon. Thus, users of the digital fragrance system would smell a lemon scent before a tobacco scent due to the higher mass of the lemon scent molecules. In order to compensate for this scent detection difference, the digital fragrance system can adjust the flow rate of the air through the fragrance cartridges based upon the molecular weight. In an embodiment, the airflow rate through the fragrance cartridges can be inversely proportional to the molecular weights of the fragrance molecules. For example, in order to increase the speed of detection of lower molecular weight fragrances, a higher airflow rate can be used. 
     Citrus type scent molecules have accelerated scent timing within the human olfactory system. The human sense of smell, or olfaction, is a form of chemoreception, which means human noses transduce chemical signals into neural impulses. Human noses possess nearly four hundred olfactory receptors, and each of these bind with a specific molecular feature. Odorous molecules possess multiple features and will trigger different receptors to varying degrees. These stimuli are then transduced into electrical signals that the human brain can interpret the olfactory receptor signals. A lemon scent will trigger receptors that will get the olfactory receptor signals to brain faster as well than lower molecular weight scents. 
     In an embodiment, the duration of the airflow through the fragrance cartridges can be variable and based upon the strength or perceived strength of the fragrance. A fragrance that has a lower strength may require more airflow through the fragrance cartridge may require more airflow than a higher strength fragrance. In an embodiment, the fragrance system can determine and store the strength values for different fragrances. The fragrance system can be configured to adjust the duration of the airflow through the fragrance cartridges based upon the strength or perceived strength of the fragrance, with a longer duration airflows for weaker strength fragrances and shorter duration airflows for stronger strength fragrances. The fragrance strength can be determined experimentally or based upon measurable chemical characteristics of the fragrance molecules. 
     In an embodiment, the digital aroma system can include software algorithms that recognize the type of scent that is in the fragrance cartridge  101  based upon identification data on the RFID tag  241  read by the RFID reader  243 . By knowing the molecular weight of the fragrance in the fragrance cartridge  101  the digital aroma dispersion system can deploy the proper right number of dry fragrance molecules to into the space required with the proper airflow. Applying identical air pump flow rates and durations to all fragrance cartridges can result in non-uniform fragrance delivery perception of the fragrance recipients. To create a uniform fragrance perception, the inventive digital aroma system can apply variable airflow controls based upon the fragrance being dispersed. The digital aroma system can use a lower airflow rate and can use shorter dispersion durations for higher molecular weight fragrances. 
     In an embodiment, an airflow rate and duration of airflow can be configured for each different fragrance cartridge so that the fragrances are uniformly sensed by system users. Imperial testing or dry fragrance analysis can determine these airflow rate and duration of airflow settings. Once the airflow rate and duration of airflow are determined, this information can be stored in a memory of the digital aroma system. When the fragrance cartridge is inserted into the digital aroma system, the system can recognize the fragrance from identification information such as an RFID tag and then apply the stored airflow rate and duration of airflow when the fragrance is requested. 
     In other embodiments, the fragrance cartridges can be configured for the number of dry fragrance particles emitted by the fragrance cartridges can be proportional to the number of dry fragrance beads in the fragrance cartridges since each fragrance bead can provide a uniform surface area. In an embodiment, the number of fragrance beads in the fragrance cartridge can be proportional to the molecular weight of the dry fragrance particle so that the perceived fragrance intensity will be uniform for all fragrance cartridges based upon the same uniform air flow and duration processing. A higher molecular weight fragrance can be recognized by the digital aroma system and when this fragrance is requested, the air flow rate and/or duration through the fragrance cartridge  101  can be lower than that of a lower molecular weight fragrance. 
     In an embodiment, the digital aroma system can be used with various spaces. The inventive In an embodiment, the system can recognizes the type of fragrance that is in the fragrance cartridge  101  based on the RFID tag  241  and adjusts the air flow speed and the intermittent adjustments for low, medium and high intensity of the fragrance desired in the space. A fragrance that has a lower molecular weight such as citrus can require more air flow to properly disperse the dry fragrance in the space than a higher molecular weight fragrance such as tobacco. If the space is large, the airflow speed and the duration of the fragrance dispersion can be increased. In contrast, for a smaller space, the airflow speed and the duration of the fragrance dispersion can be decreased. 
     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 a video image. The system monitor sensor  225  can be coupled to the 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 digital aroma system components can operate in conjunction to perform various functional actions that can be performed with software running on the processor  227 . 
     In some embodiments, the digital aroma system can recognize video encoded fragrance markers in the video media. The encoded fragrance markers can identify a specific fragrance that is read by the video object recognition system resulting in the identified fragrance being delivered to the user. This feature can be useful in providing a smell before an image corresponding to the fragrance is displayed. For example, the camera point of view in a video may be approaching a fire. The smoke from the fire may be blowing towards the camera and a person at the camera position may smell the smoke before seeing the fire. In order to accurately recreate this scenario the video media may use an encoded fragrance marker for smoke, which is detected by the video object recognition system. The video object recognition system can then emit the smoke fragrance before the fire is shown on the video. 
     For example, a digital media can include aroma output signals, which can be a video encoded fragrance marker, and the media player can transmit the scent output signal(s) to the trigger input  221  which can be received by the processor  227 . The aroma output signals can include aroma identification and the processor  227  can access the scent database  229  to identify the location of the corresponding fragrance cartridge and the valves that must be open to access the identified fragrance cartridge. The processor  227  can then transmit control signals to the valve controllers  233  which actuate the valves  237  to open an airflow path to the identified fragrance cartridge. 
     In an embodiment the trigger input can be transmitted within a short-range proximity through a device such as a Bluetooth receiver or other local communications device. The aroma system can be used with a mobile device such as a smart phone that is carried by the user. When the user walks within a museum to different exhibits, the trigger input  221  of the digital aroma system can detect trigger signals from different exhibits as the user walks and the aroma system can emit the scent as commanded by the detected trigger signals. In other embodiments, the present invention can be used in many different individual educational settings like museums to provide a cost effective sensory experience using media, software, maintenance and aroma. 
     In an embodiment, the sensor input  223  can be a camera and the processor  227  can run a video object 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 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 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. 
     In an embodiment the 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 fans/pumps  239  to actuate the fragrance delivery. 
     In an embodiment, the 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 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 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. 
     In another embodiment, the digital aroma system can be used with a fragrance sensor that can measure the intensity or concentration of the dry fragrance particles in the air space around the digital aroma system. With reference to  FIG. 30 , the sensor input  223  can be a fragrance sensor(s). By detecting the concentration of the fragrance, the system can be configured to maintain a fragrance concentration within a specific range. With reference to  FIG. 31 , the fragrance concentration sensors  308  can detect the fragrance concentration within a vehicle  301  and the fragrance system can be configured to emit the dry fragrance from fragrance emission unit vents  305  when the system receives a manual nausea input or predicts passenger nausea based upon rotation or acceleration and duration above predetermined threshold values. 
     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. 
     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. 
     The Fragrance 
     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. 
     In an embodiment, the system can detect the concentration distribution of the fragrance with a plurality of fragrance sensors  308  placed in a plurality of locations in the vehicle  301  such as above each passenger seat. When multiple sensors  308  are used, the sensor network can determine the fragrance emission pattern based upon the detected fragrance concentrations of the sensors. This fragrance information can be used to properly orient the fragrance output from the system to asymmetrically direct fragrance to the passenger(s) in the vehicle. In an embodiment, the system detect the locations of people into the vehicle  301  with sensors such as proximity sensors  308  which can be located by each seat in the vehicle. When people are not in one or more of the seats, the system can stop the emission of fragrances from the fragrance emission vents  305  to these locations. When a person enters the vehicle  301 , the system can detect the person or people and the fragrance emission unit  305  can emit a fragrance, which can be experienced by people in the vehicle  301 . For example, the system can use sensors in the seats such as seatbelt weight sensors can be used to identify the seats where passengers are sitting. 
     In addition to detecting the concentration of the system fragrances, the fragrance sensors  308  can also be used to detect outside odors which can influence the user&#39;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. 
     The fragrance sensor  308  can be based upon sensor mechanisms such as chemo sensors or by gas chromatography, which provides information about volatile organic compounds. Electronic fragrance sensors  308  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 can be sensitive to all fragrance molecules but can be able to distinguish different fragrance particles. The fragrance sensor 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 sensors 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. 
     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&#39;s stored profile. Digital Scent 3.0 Platform with Rideshare Reference Software Architecture and APIs 
     When a rider orders a ride, the fragrance request can be received by the fragrance system of the driver&#39;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. 
     In the present 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 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 digital aroma system invention also addresses the issue of ease of replacement of the fragrance cartridges by the consumer. The digital aroma system allows the swapping out of several fragrances simultaneously by removing and replacing a single cassette of the digital aroma system. The cassette can contain six or more individual fragrance cartridges containing dry fragrance infused substrate materials. In other embodiments, the cassette is not limited to six fragrance cartridges. For example, the cassette can hold a single fragrance cartridge and in other embodiments the cassette can have couplings to hold ten to twenty or more fragrance cartridges and in a cassette system. In addition the consumer can also change each individual aroma cartridge within the cassette system be simply exchanging each aroma cartridge within the cassette or replacing the entire cassette. 
     The digital aroma system can include a cassette having a manifold, which holds a plurality of fragrance cartridges. The manifold has air inlets and scent outlets that are coupled to the fragrance cartridges which can have hollow housings which are filled with dry fragrance infused particles such as balls or other loose objects. The cartridge housings can have couplings such as threads or tabs, which can provide a gas tight connection between the cartridges and the manifold. The couplings also allow users to replace or change the fragrance cartridges. The cartridges can also have identification mechanisms, which provide an identification signal output such as a radio frequency identification tag. The identification signal output can identify the fragrance in the cartridge and control the number of fragrance outputs that the cartridge can provide. The digital aroma system can have readers, which can read the identities of the fragrance in the cartridges and store this fragrance and cartridge location information so that desired fragrance can be controlled to emit by the digital aroma system. 
     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&#39;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&#39;s interior. In an embodiment, up to 5 selectable fragrances including an anti-nausea fragrance to personalize the driving experience. In other embodiments, any number of fragrances or combinations of fragrances can be selected. The scent cartridges provide ease of use for replacement by the car dealer or by the consumer. 
     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 a mobile smart phone or a display on a vehicle. 
     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 dispersions. Because these warnings are time based, they are not indicative of a specific percentage dispersions remaining. 
     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. Similarly, based upon infrequent use, the system may recommend using a lower capacity fragrance cartridge for less popular fragrances that has a history of lower rates of dispersion over time than the more popular fragrances, so multiple fragrance cartridges will needing replacement at the same time. 
     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 smart phone and/or an in-dash mobile control unit. A driver or passenger of the vehicle can interact with the smart phone and/or an in-dash mobile control unit to control the operation of the fragrance dispersion module. The smart phone 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. 
     The system servers can also use the cumulative data measurements to collect data for a large number of installed fragrance dispersion systems. This data can be grouped by region, user information, season, temperature, country or any other distinguishing characteristic. By understanding the preferences of a large user group, the system servers can provide business intelligence for advanced planning, real time trending, geographic trending and dashboard reporting. For example, each fragrance dispersion system can transmit fragrance dispersion information to a central server(s) and this data can predict the rate of consumption for each type of fragrance cartridge. This information can then be used to order additional fragrance cartridges so that adequate quantities will be available when needed. This information can also be used to identify popular and unpopular fragrances. If a fragrance is not being consumed in reasonable quantities, the system may determine that a specific unpopular fragrance may have a quality control problem and the inventory may need to be replaced. Alternatively, the system may request that an unpopular fragrance be discontinued or modified to be more accepted by consumers. This information may also be used to determine fragrance trends so that new fragrances can be developed that are similar to the most popular existing fragrances. 
     The data can also be used by the server to identify correlations between user demographics and preferred fragrances. For example, the system may detect differences in fragrance preferences between men and women and children where men prefer an outdoors forest fragrance, women prefer a floral fragrance and children may prefer a beach fragrance. By knowing the fragrance preferences based upon user demographics, the server can make fragrance preference predictions for future consumers based upon specific user, geography, vehicle type, season, etc. If an automobile buyer decides to purchase a vehicle with the fragrance dispersion, the user information can be provided and used to predict a set of fragrance cartridges that are most likely to be popular with the consumers. Alternatively, the consumer may be able to select the individual fragrances to be supplied with the vehicle. 
     The fragrance consumption information from the data can be displayed in various ways on system servers including: numerical data, graphical data showing fragrance consumption trend lines in a vertical axis over time on a horizontal axis, bar or pie charts, current fragrance levels for a specific fragrance system, etc. In an embodiment, the fragrance consumption information can be transmitted to the integrated mobile control and/or smart phone so that the users will know their consumption rates, fragrance levels, fragrance cartridge refills needs and compare their personal use information to general user information. 
     In an embodiment, the inventive system can perform various processes to detect and predict vehicle movements that will result in nausea. With reference to  FIG. 32 , a flowchart is illustrated that describes a manual method for actuating the anti-nausea fragrance output and recording. 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  401 . 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  403 . 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&#39;s nausea input and this information can be stored by the system in a nausea location database  405 . 
     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&#39;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. 
     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. 
     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&#39;s location for the group of passenger(s) 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. 
     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. 
     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. 
     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&#39;s associated nausea group. 
     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 more steady 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. 
     This movement data can be used to identify and predict future conditions that can result in nausea. With reference to  FIG. 33 , a flowchart showing a predict nausea process is illustrated. The system can detect the rotation and acceleration movements of the vehicle and user and the duration of the motions in real time  411 . 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  413 . 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  415 . The system can then output the anti-nausea fragrance in a volume that corresponds to the predicted nausea level  417 . 
     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 centripital =V 2 /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. With reference to  FIG. 34 , the inventive system can be used to provide route predictive nausea services. The user can input a destination  421 . The GPS system can respond by determining a route to the destination  423 . 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  425 . 
     The system can then analyze possible routes and identify the locations that may result in nausea based upon the passengers&#39; 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  429 . 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  431 . 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  433 . 
     In another embodiment, the digital aroma system can be used with a fragrance sensor that can measure the intensity or concentration of the dry fragrance particles in the air space around the digital aroma system. With reference to  FIG. 31 , the sensor input  223  can be a fragrance sensor(s). By detecting the concentration of the fragrance, the system can be configured to maintain a fragrance concentration within a specific range. With reference to  FIG. 32 , the fragrance concentration sensor  303  can detect the fragrance concentration in a room  301  and the fragrance system can be configured to emit the dry fragrance from a fragrance emission unit  305  when the fragrance concentration drops below a predetermined threshold value. This type of active monitoring system can compensate for stagnant air by reducing the frequency of fragrance emissions or compensate for higher than normal airflow by increasing the fragrance emission rate. The fragrance concentration sensor(s)  223  can be placed in any location(s) in the room  301 . When multiple sensors  303  are used, the sensor network can determine the fragrance emission pattern based upon the detected fragrance concentrations of the sensors. This fragrance information can be used to properly orient the fragrance output from the system to generate a uniform fragrance in the space. In an embodiment, the system detect the movement of people into the room  301  with a sensor such as a proximity sensor  307  which can be located by an entrance or a door. When people are not in the room  301 , the system can stop the emission of fragrances from the fragrance emission unit  305 . When a person enters the room  301 , the system can detect the person or people and if the fragrance concentration is low, the fragrance emission unit  305  can emit a fragrance, which can be experienced by people in the room  301 . 
     In another embodiment, the digital aroma system can be used with a fragrance sensors that can measure the intensity or concentration of the dry fragrance particles in the air space in a residential or commercial room. By detecting the concentration of the fragrance, the system can be configured to maintain or refresh a controlled fragrance concentration within a specific fragrance concentration range. With reference to  FIG. 35 , the fragrance concentration sensor  303  can detect the fragrance concentration in a room  301  and the fragrance system can be configured to emit the dry fragrance from a fragrance emission unit  305  when the fragrance concentration drops below a predetermined threshold value. This type of active monitoring system can compensate for stagnant air by reducing the frequency of fragrance emissions or compensate for higher than normal airflow by increasing the fragrance emission rate. The fragrance concentration sensor(s)  223  can be placed in any location(s) in the room  301 . When multiple sensors  303  are used, the sensor network can determine the fragrance emission pattern based upon the detected fragrance concentrations of the sensors. This fragrance information can be used to properly orient the fragrance output from the system to generate a uniform fragrance in the space. In an embodiment, the system detect the movement of people into the room  301  with a sensor such as a proximity sensor  307  which can be located by an entrance or a door. When people are not in the room  301 , the system can stop the emission of fragrances from the fragrance emission unit  305 . When a person enters the room  301 , the system can detect the person or people and if the fragrance concentration is low, the fragrance emission unit  305  can emit a fragrance, which can be experienced by people in the room  301 . 
     With reference to  FIG. 36 , in an embodiment the fragrance concentration sensors  303  and fragrance emission units  305  are positioned in a larger room  311  and arranged in an array distributed across the larger room  311 . In these embodiments, the system can identify the fragrance concentration sensors  303  which have a lower than specified fragrance concentration which can cause the system to respond by emitting fragrances from the fragrance emission unit(s)  305  that are closest to the fragrance concentration sensors  303  which detected the lower than specified fragrance concentration. By controlling the emissions from multiple fragrance emission units  305  the desired fragrance levels can be maintained through the room  311 . 
     In an embodiment, the fragrance concentration sensors  303  can be used to optimize the positions of the fragrance emission units  305  within a room  311  based upon the airflow pattern through the room  311 . For example, when there is airflow through a room  311  due to heating, ventilation and air conditioning (HVAC) systems. Alternatively, the fragrance emission units  305  can be integrated into the HVAC systems. For example, if the fragrance concentration sensors  303  do not detect a uniform fragrance concentration level, the system can suggest moving the fragrance emission units  305  towards the fragrance concentration sensors  303  that have a lower fragrance level reading and away from the fragrance concentration sensors  303  that having a higher fragrance level reading. In an embodiment, the system can make suggestions for position locations for the fragrance emission units  305  within a room  311  for uniform fragrance dispersion. 
     The fragrance sensor  303  can be based upon sensor mechanisms such as chemo sensors or by gas chromatography, which provides information about volatile organic compounds. Electronic fragrance sensors  303  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 can be sensitive to all fragrance molecules but can be able to distinguish different fragrance particles. The fragrance sensor 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 sensors 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. 
     The present invention addresses several issues that are currently found in gaming and movie environments. Some fragrance systems have been tried to use scented oils, which are cumbersome and messy. In contrast, the inventive digital aroma system uses fragrance cartridges, which have dry beaded sealed units, coupled to a cassette and manifold which provides a self-contained system. The fragrance is from dry particles, which are infused into substrates such as beads that remain enclosed in individual chambers that seal the aroma for freshness until the fragrance cartridge is installed in the digital aroma system and delivered through the scent outlet to the user. Because of the dry nature of the fragrance materials there is no lingering aroma effect and no volatile organic compounds (VOCs). 
     In the present 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 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. 
     In an embodiment, the fragrance systems can be used to create a mood scent experience that can coordinate lighting, scent and audio systems which are all integrated. Each of these experiences can be coordinated by a desired mood or activity. For example, a system may have a user interface with a plurality of moods and/or activities that can be selected by a system user such as: dinner party, Friday night, festival, workout, road trip, studying, game day, BBQ, family time, wake up, focused, raining day, in love, wind down, memory lane and any other mood/activity. When a mood/activity is selected by pressing a button  351 , voice control or any other input, the system can cause the lighting, scent and music to produce outputs that are coordinated with the selected mood/activity. The lighting output can be blue for increased productivity, positive environment, reduce depression, less anxiety and peacefulness. The lighting output can be yellow for increased competence, happiness, light and joyfulness. The lighting output can be red for increased excitement, love, enthusiasm and passion. The lighting output can be green for increased rejuvenation, freshness and vigor. 
     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 smart phone 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. 
     Studies have been performed on the effects of different fragrances on nausea. The Iranian Red Crescent Medical Journal, published a 2012 study of the Effect of Mint Oil on Nausea and Vomiting During Pregnancy. In the study, the severity of nausea showed a decreasing trend (especially in 4th night) in the mint test group and increased in the control group. Pasha, H., Behmanesh, F., Mohsenzadeh, F., Hajahmadi, M., &amp; Moghadamnia, A. A. (2012). Study of the Effect of Mint Oil on Nausea and Vomiting During Pregnancy. Iranian Red Crescent Medical Journal, 14(11), 727-730. http://doi.org/10.5812/ircmj.3477 Integrative Medicine Insights published an article The Effectiveness of Ginger in the Prevention of Nausea and Vomiting during Pregnancy and Chemotherapy. The paper concludes that the best available evidence demonstrates that ginger is an effective and inexpensive treatment for nausea and vomiting and is safe. Lete, I., &amp; Allue, J. (2016). The Effectiveness of Ginger in the Prevention of Nausea and Vomiting during Pregnancy and Chemotherapy. Integrative Medicine Insights, 11, 11-17. http://doi.org/10.4137/IML.S36277 Phytomedicine published a paper A multi-center, double-blind, randomised study of the Lavender oil preparation Silexan in comparison to Lorazepam for generalized anxiety disorder. The paper states that lavender oil preparation silexan appears to be an effective and well tolerated alternative to benzodiazepines for amelioration of generalised anxiety. Woelk, H., &amp; Schläfke, S. (2010). A multi-center, double-blind, randomised study of the Lavender oil preparation Silexan in comparison to Lorazepam for generalized anxiety disorder. Phytomedicine, 17(2), 94-99. The Iranian Red Crescent Medical Journal published a 2014 paper on the effect of lemon inhalation aromatherapy on nausea and vomiting of pregnancy. The paper states that inhalation aromatherapy with Lemon essential oil showed that this method could reduce nausea and vomiting during pregnancy (NVP). In contrast to chemical medications, aromatherapy has useful effects on physical and psychological health and might be useful as an alternative approach in the treatment of NVP. In an embodiment, the anti-nausea fragrance is a proprietary blend of dry of at least 2 of the following scents: Peppermint, Spearmint, Lemon, Ginger, and Lavender. The percentages of each scent of the proprietary blend varies on the combination and does not always include all of these ingredients. 
     The fragrance system can also be used to produce other specific purpose sensory experiences. For example, a cinnamon fragrance can be used for concentration and focus. Researchers from Wheeling Jesuit University found that those who smelled a cinnamon fragrance improved in cognitive functions like visual-motor response, working memory and attention span. A pine fragrance can be used to decrease anxiety, according to a Japanese study in which participants reported significantly lower depression and stress levels. The research also discovered that anxious subjects had a greater feeling of relaxation after indulging in the pine fragrance. Fresh-cut grass fragrances can make users more joyful. In a study (ISOT/JASTS 2004), researchers found that taking a vanilla bean fragrance elevated participants&#39; feelings of joy and relaxation. A small study out of Wheeling Jesuit University found that smelling a peppermint fragrance could be linked to greater cognitive stamina, motivation and overall performance. A 2010 study, Nat. Prod. Commun. 2010 January; 5(1):157-62, “Stimulating effect of aromatherapy massage with jasmine oil” found that not only does the smell of jasmine create a sense of alertness, it can also serve as a way to help with depressive thoughts. Researchers found that the stimulating effect of jasmine fragrance can aid in the relief of depression and can lead to an uplifted mood. Research has suggested that the smell of apple fragrance may actually help ease a migraine. One 2008 study showed that those who found the scent appealing had a noticeable reduction in headache symptoms as well as shortened migraine episodes. Previous studies on a green apple fragrances have also found the scent may help control feelings of anxiety during stressful moments. In some embodiments, vehicle model specific or vehicle make specific fragrances can be developed and these special fragrances can be supplied with the vehicle model or all vehicles produced by a vehicle make. 
     The sensory experience network system can also coordinate audio signals within the vehicle with the lighting and scent. Music appropriate for each of the moods and activities can be played in a random sequence of songs or ambient background sounds. In some embodiments, the integrated mobile control and/or smart phone may have special fragrances for assisting with special physical conditions such as alertness and nausea. In an embodiment, the user interface of the integrated mobile control and/or smart phone may have an “alert” button that can result in a fragrance that can improve the alertness of the driver or passengers. For example, fragrances like lemon, orange, cinnamon, mint and rosemary can help boost energy and alertness.

     With reference to  FIG. 37 , a flow chart of an embodiment of a fragrance system is illustrated. In an embodiment, a user can select access the fragrance system controls by pressing a fragrance icon  351  on a user interface of the integrated mobile control and/or smart phone. The system can respond by displaying a plurality of moods or activities  355 . The user can then select a desired mood or activity  355 . The system can choose a fragrance  357  or the system can be pre-configured with fragrance(s)  359  that correspond to the different moods or activities  355 . The system can then actuate and disperse a fragrance or fragrances  359  associated with the user selected mood  355 . 
     The user may need to adjust the system control settings  363  and the system user interface can have adjustments for the dispersion intensity setting  365 . In the illustrated example, the user can configure the dispersion output for the fragrance cartridge to low, high or normal  365 . In other embodiments, the system can have any other variable settings. The fragrance system can keep track of the activations  361  and dispersions for each fragrance cartridge and determine the status of each fragrance cartridge and calculate the number of dispersions left and if there are more dispersions available for each cartridge  367 . The system can determine if the cartridge needs to be replaced  369  before the fragrances are fully depleted from the cartridges. The fragrance system may automatically order replacement fragrance cartridges  371  when the number of remaining fragrance dispersions is low. If the cartridges need to be replaced, the system can provide an alarm which can provide a signal to the user interface that may instruct the user the user to replace the cartridges  373 . The system may instruct the user on how to replace the fragrance cartridges when they are depleted. The process can be repeated after each fragrance dispersion. 
     The described software can be used to control cartridge efficiency, monitor usage, data collection and alerts for replenishment. The network system can be linked to supply chains for consistent usage, automated replenishment and billing based upon predicted and actual usage. System planning based upon real time trending, geographic trending, dashboard reporting. Web interface programming of devices (SDK), smart phone compatible. 
     With reference to  FIG. 38 , in an embodiment, a specific process can be performed construct the fragrance cartridges and recycle the fragrance cartridges components. The fragrance oils or other fragrance media are received and cataloged  321 . The beads are placed in or near the fragrance oil and the fragrance oils or other fragrance media are infused into beads  323 . The bead fragrance infusion process can take up to four weeks. After the beads have been infused with a fragrance, the fragrance infused beads are placed in fragrance cartridges and the fragrance cartridges can be packed  325 . The filled fragrance cartridges are shipped to distributors, dealers and/or directly to consumers  327 . The fragrance cartridges are then inserted into the fragrance dispersion units and used by the end consumers  329 . Air is blown through the fragrance cartridges and the dry fragrances are blown off of the fragrance beads. At the end of the dispersion cycle life, the fragrance cartridges are removed from the fragrance dispersion units and replaced with new fragrance cartridges. The depleted fragrance cartridges can then be recycled  331 . In an embodiment, the fragrance cartridges are disassembled and the fragrance depleted beads are removed from the cartridges  333 . The beads and cartridges can be recycled  335 . The used beads can be cleaned and re-infused with the fragrances  323 . Once re-infused, these fragrance beads can be placed in a fragrance cartridge  325  and the consumption process can be repeated. 
     In an embodiment, fragrance data can be collected by a server in communication with the fragrance systems located throughout the world. The collected fragrance data can be used to improve fragrance formulas and predict the appeal of fragrances over a wide variety of environmental conditions. Fragrances that are detected by peoples&#39; noses which results in a direct connection to the system users&#39; brains which results in memories and experiences. Fragrances can provide state of mind triggers which can result in specific mindsets and human behaviors such as enhanced alertness, emotional states. In an embodiment, the fragrance data can be used for human mood mapping. The fragrance data can identify the specific moods that result from exposure to specific fragrances. For example, citrus fragrances can excite the fragrance system user, a lavender fragrance can have a calming effect, a rosemary fragrance can result in improved mental focus. Fragrance exposure can also provide health wellness benefits. Some fragrances can result in emotional well-being, stress relief, motion sickness relief, etc. By analyzing the fragrance data, the fragrance systems can be used to effectively test and determine optimal fragrance blends and exposures which will most universally result in the desired human reaction. By optimizing the fragrance output of the fragrance system, all installation environments can be improved. System users will have enhanced experiences, ride sharing will have reduced malodors, hospitality service providers will have increased brand loyalty due to improved experiences, connected homes will be able to enhance the mood and wellness of the occupants, and retail stores will be able to improve customer experiences which can result in increased sales. The fragrance technology platform can be integrated into digital scent solutions for various consumer product lines and commercial services which can quickly, conveniently, and cost-effectively add premium scent solutions to their offerings to increase market share and revenue. The fragrance technology platform can also provide a data-centric architecture for scent that includes Infusion, Diffusion and Insights (Data Cloud). The collected fragrance data can be used for determining environment-specific fragrance profiles. 
     In an embodiment, the fragrance system can include a server which receives information from fragrance dispersion units which can transmit fragrance output data, fragrance cartridge purchase information, date and time of fragrance dispersion information, location information, and other information. From the fragrance information received, the server can produce reports which indicate the fragrance popularity based upon time and place.  FIG. 39  illustrates a graphical representation of the number of diffusions in the vertical Z axis, month of the year in the X axis and fragrance name in the Y axis. In the illustrated example, the fragrance “Warm &amp; Spicy” has more diffusions in the winter months of October through February than in the supper months of March-August  FIG. 40  illustrates a diagram showing the popularity of fragrances based upon specific city locations. By knowing the popularity of fragrances based upon time and place, the server can provide recommendations for user&#39;s wanting suggestions for fragrance purchases. 
     The fragrance profile data can also be used with software algorithms to predict the fragrance system performance characteristics and improve upon the fragrance formulations and output efficiency. A good and constant scent perception in the cabin means a constant and controlled concentration of the fragrance in the air. Using scented dry beads eliminates all the biggest issues of liquid fragrance diffusion, but the fragrance concentration of scented dry beads, without control, is variable and depends on each fragrance oil. The inventive fragrance platform adapts the fragrance diffusion parameters in real time to guarantee a constant concentration in the cabin for each fragrance. For this, the fragrance system characterizes the behavior of each fragrance in a Scent Diffusion Profile that is used by the scent device to control the diffusion without additional computational resources. 
     The server can provide fragrance analytics based upon the fragrance information received by fragrance diffusion systems. The server can analyze the following data: Fragrance Popularity, Notes Popularity, ambient temperature, outdoor temperature, Ingredient Popularity, Location, Household, user Sex, Date/Time, Month and scent popularity data, City and scent popularity data, etc. 
     In an embodiment, the fragrance system can perform fragrance benchmarking methods. The process can include: 
     Step 1: Data Acquisition on how the scent is diffused over the time at different temperatures can be an automatic process that lasts about 4 days per fragrance. The metric of Scent diffusion can be expressed in mg of pure oil diffused per cubic meter per hour with the corresponding temperatures that the fragrances are dispersed at. 
     Step 2: Definition of Scent Intensity Minimum Threshold. A specific protocol for the fragrance data analysis can include a jury of 6 experts including a nose and chemist that determine, for each fragrance, the scent concentrations (in mg/m3/h) for minimum and maximum perceptions. Based upon the feedback from the fragrance protocols, fragrance formulations can be created. The quality of the fragrance formulations can be certified by the perfumers. 
     Step 3: Algorithm. A min and max scent concentration (mg/m3/h) can be determined to reach user perception data collected and with the target (size of the area to perfume and life of the cartridge). An algorithm can be used to define the best cartridge size and the scent diffusion cycles needed to apply to maintain a constant scent concentration in the air over the period of time. 
     With reference to  FIG. 41 , a block diagram of the process used to monitor and improve fragrance formulations is illustrated. The infusion process includes the processes for infusing fragrances into fragrance beads which are used in the fragrance cartridges. The infusion testing can include infusion lab testing which can put fragrances such as oils in the dry beads. The infusion performance test data can include payload density and confirming that the infused fragrances never separates from the beads in high-heat conditions which can result in changing the smell emitted by the fragrance cartridges. Health Parameters are important considerations of the fragrance system where the fragrance cartridges have the following characteristics: No VOCs, No solvents, Non-carcinogenic, and No liquid. The fragrance system should also comply with Green Sustainability by using Natural Ingredients, use Fair Trade sourcing, and use fragrance beads made from Reusable Polymers. 
     Delivery Data is obtained from the diffusion of the fragrances. The Performance Data can be processed by Scent Profile Algorithms. The delivery data can include Depletion Level of the fragrance cartridges over diffusions, MOS Chip Authentication, Fragrance Intensity Levels, Cadence which can be the rate at which the diffusions of the fragrance cartridges are applied, testing of multiple fragrance Cartridges with different scents, checking to confirm that there is No Cross Contamination of fragrances, etc. The fragrance system can also check that the diffusions meet specific Health Parameters including: Dry-Air Diffusions, Lowest PPM Molecules, confirming that the fragrance system is Fully Air-Tight, and the fragrance system does not leave any lingering scents, etc. The fragrance system can be Green Sustainability compliant by using re-usable Cartridges. 
     The Data Analytics can provide the following fragrance cartridge Insights Performance Data based upon the following data: What fragrance is Released, when if the fragrance Released, Where is the fragrance Released, What was the Cartridge Load Date, what is the fragrance cartridge Expiration Date, what is the Temperature during the fragrance diffusion, What is the ambient Traffic level, what are the fragrance Intensity Preferences, what are the fragrance cartridge Cadence Preferences, Scent Preferences, fragrance Survey Data and Supply Chain Data, etc. 
     The Benchmarking and Creating of the Scent Diffusion Profile can include fragrance infusion. The infusion process can include various process steps. Each new fragrance can be progressively infused and tested. The data acquired can include: Fragrance concentration and Scented beads density. An example of the fragrance data acquired is illustrated in Table 1 below.

     Benchmarking/Creating the Scent Diffusion Profile. Step 2: data acquisition during controlled diffusion. Each new fragrance cartridge is tested in a data acquisition tool during 72 hours. Several parameters are tested including: Air flow configuration, Temperature data for the fragrance diffusions, Data acquired, Fragrance concentration, VOC concentration, CO2 concentration, PM2.5 et PM10 concentration, Temperature, Humidity, etc. 
     The Benchmarking and Creating of the Scent Diffusion Profile can include step 2 which is defining of Scent Intensity Minimum concentration specific protocol with a jury of 6 experts including a nose and chemist on staff that determine, for each fragrance, the scent concentrations (in mg/m3/h) for minimum and maximum perceptions. The data records for the fragrance measurements can include: Data acquired, Scent concentration for minimum perception, and Fragrance strength. Table 2 illustrates another example of the fragrance data acquisition data.

     The process for Benchmarking and Creating the Scent Diffusion Profile can include Step 4: Scent diffusion modelization. For each fragrance, the data collected is processed and the model creates its Scent Diffusion Profile. The model accepts several granularity levels: Low definition (8 bytes) where the cartridge&#39;s life is divided in 8 steps and High definition (256 bytes) where the cartridge&#39;s life is divided in 256 data steps. In other granularities, other numbers of bytes can be used. The model can create the Scent Diffusion Profile in 4 formats: Raw data array, SQL data array, ASM code ready to use in non-connected device, and C code ready to use in non-connected device. An example of a 8 byte scent diffusion profile is illustrated in Table 3 below for the fragrance OH L&#39;AMORE.

     The Benchmarking/Creating the Scent Diffusion Profile can also include a Step 5: Model validation process where each fragrance is tested one last time to compare the model to the fragrance diffusion. The data acquisition tool edits automatically its final report.  FIG. 42  illustrates an example of fragrance final report. 
     The fragrance system can include a Scent Diffusion Predictive Algorithm. Each fragrance is characterized by a Scent Diffusion Profile stored in the data base of the fragrance system server memory. The fragrance profiles can include: 8, 16, 32, 64, 128, or 256 bytes definition profiles with lower byte profiles providing a low definition scent profile to a high byte profile having a high definition profile. Each fragrance cartridge can be registered in the Scent fragrance database. When the cartridge is authenticated the Scent Diffusion Profile is downloaded from the server database and the past usage is downloaded from the scent fragrance database. When a diffusion is applied on the cartridge: the Scent Diffusion Profile associated to the fragrance diffused is used by the fragrance system hardware, the history of the previous fragrance diffusion is used and then, the Predictive Scent Diffusion Algorithm computes the parameters of the diffusion cycle. 
     The Scent Diffusion Predictive Algorithm can be used to control the fragrance system hardware. The fragrance diffusion is characterized by the fragrance cartridge that is selected by the system users. A loop of diffusion cycles is launched. The algorithm results in the fan of the fragrance system being activated during Ton seconds. The fan is stopped during Toff seconds. The parameters for each diffusion cycle (Ton and Toff) must be computed by the algorithm. 
     Scent Diffusion Predictive Algorithm can utilize various data. Data stored in the algorithm can include: Scent Diffusion Profiles 4× (8, 16, 32, 64, 128 or 256 bytes), Cartridges ID 4× (8 bytes), and Cartridge History 4× (1 byte). The system can have an input of the fragrance Cartridge ID which can be read by a sensor on the fragrance diffusion device. The system output can include: parameters of diffusion cycle: Ton and Toff. The algorithm can result in the server performing the actions of authenticating every new cartridge and in response, the corresponding Scent Diffusion Profile is received and computing the parameters Ton and Toff. Using the parameters Ton and Toff to send local interconnect network (LIN) commands to start/stop the fan. 
     The inventive fragrance system can include a server which can obtain fragrance data from the plurality of fragrance dispersion system and stores the fragrance data on a fragrance database. The fragrance information received by the server has been described above. The server can process the received fragrance data and provide recommendations for fragrances to existing and new fragrance system users. The recommendations and reformulations can be based upon popularity by location, time, date, user information, etc. Thus, the server can recommend fragrances which are popular for user&#39;s who are located in the same area for the same time period and have similar personal characteristics. The server can also reformulate existing fragrances based upon user feedback and efficacy. For example, multiple anti-nausea fragrances can have used by fragrance dispersion systems and efficacy feedback data can be transmitted to the server. The most effective note or ingredient in the anti-nausea fragrances can be determined based upon the feedback with user information. The server can recommend the anti-nausea formulation which has the best efficacy. Through the described processes, the fragrance cartridges can be improved over time with accumulated fragrance data.

The information carrier may be a non-transitory computer- or machine-readable storage medium, such as the memory  904 , the storage device  906 , or memory on processor  902 . 
     The high speed controller  908  manages bandwidth-intensive operations for the computing device  900 , while the low speed controller  912  manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In one implementation, the high-speed controller  908  is coupled to memory  904 , display  916  (e.g., through a graphics processor or accelerator), and to high-speed expansion ports  910 , which may accept various expansion cards (not shown).

     The computing device  900  may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a standard server  920 , or multiple times in a group of such servers. It may also be implemented as part of a rack server system  924 . In addition, it may be implemented in a personal computer such as a laptop computer  922 . Alternatively, components from computing device  900  may be combined with other components in a mobile device (not shown), such as device  950 . Each of such devices may contain one or more of computing device  900 ,  950 , and an entire system may be made up of multiple computing devices  900 ,  950  communicating with each other. 
     Computing device  950  includes a processor  952 , memory  964 , an input/output device such as a display  954 , a communication interface  966 , and a transceiver  968 , among other components. The device  950  may also be provided with a storage device, such as a Microdrive, solid-state memory or other device, to provide additional storage. Each of the components computing device  950 , processor  952 , memory  964 , display  954 , communication interface  966 , and transceiver  968  are interconnected using various busses, and several of the components may be mounted on a common motherboard or in other manners as appropriate. 
     The processor  952  can execute instructions within the computing device  950 , including instructions stored in the memory  964 . The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may provide, for example, for coordination of the other components of the device  950 , such as control of user interfaces, applications run by device  950 , and wireless communication by device  950 . 
     Processor  952  may communicate with a user through control interface  958  and display interface  956  coupled to a display  954 . The display  954  may be, for example, a TFT LCD (Thin-Film-Transistor Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface  956  may comprise appropriate circuitry for driving the display  954  to present graphical and other information to a user. The control interface  958  may receive commands from a user and convert them for submission to the processor  952 . In addition, an external interface  962  may be provided in communication with processor  952 , so as to enable near area communication of device  950  with other devices. External interface  962  may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used. 
     The memory  964  stores information within the computing device  950 . The memory  964  can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. Expansion memory  974  may also be provided and connected to device  950  through expansion interface  972 , which may include, for example, a SIMM (Single In Line Memory Module) card interface. Such expansion memory  974  may provide extra storage space for device  950 , or may also store applications or other information for device  950 . Specifically, expansion memory  974  may include instructions to carry out or supplement the processes described above, and may include secure information also. Thus, for example, expansion memory  974  may be provide as a security module for device  950 , and may be programmed with instructions that permit secure use of device  950 . In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner. 
     The memory may include, for example, flash memory and/or NVRAM memory, as discussed below. In one implementation, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory  964 , expansion memory  974 , memory on processor  952 , or a propagated signal that may be received, for example, over transceiver  968  or external interface  962 . 
     Device  950  may communicate wirelessly through communication interface  966 , which may include digital signal processing circuitry where necessary. Communication interface  966  may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver  968 . In addition, short-range communication may occur, such as using a Bluetooth, Wi-Fi, or other such transceiver (not shown). In addition, GPS (Global Positioning System) receiver module  970  may provide additional navigation- and location-related wireless data to device  950 , which may be used as appropriate by applications running on device  950 . 
     Device  950  may also communicate audibly using audio codec  960 , which may receive spoken information from a user and convert it to usable digital information. Audio codec  960  may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of device  950 . Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on device  950 .

     To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input. 
     The systems and techniques described here can be implemented in a computing system that includes a back end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front end component (e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), and the Internet. 
     The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. 
     For the sake of clarity, the processes and methods herein have been illustrated with a specific flow, but it should be understood that other sequences may be possible and that some may be performed in parallel, without departing from the spirit of the invention. Additionally, steps may be subdivided or combined. As disclosed herein, software written in accordance with the present invention may be stored in some form of computer-readable medium, such as memory or CD-ROM, or transmitted over a network, and executed by a processor. 
     All references cited herein are intended to be incorporated by reference. Although the present invention has been described above in terms of specific embodiments, it is anticipated that alterations and modifications to this invention will no doubt become apparent to those skilled in the art and may be practiced within the scope and equivalents of the appended claims. More than one computer may be used, such as by using multiple computers in a parallel or load-sharing arrangement or distributing tasks across multiple computers such that, as a whole, they perform the functions of the components identified herein; i.e. they take the place of a single computer. Various functions described above may be performed by a single process or groups of processes, on a single computer or distributed over several computers. Processes may invoke other processes to handle certain tasks. A single storage device may be used, or several may be used to take the place of a single storage device. The present embodiments are to be considered as illustrative and not restrictive, and the invention is not to be limited to the details given herein. It is therefore intended that the disclosure and following claims be interpreted as covering all such alterations and modifications as fall within the true spirit and scope of the invention.
