Detailed Description

While the preferred embodiments of the present technology have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.

In some embodiments, the dispensing device 1000 is communicatively coupled to a smart device. The dispensing device 1000 includes sensors 340 for monitoring several data streams (i.e., the subject's heart rate, humidity, weather, location, etc.). For example, the dispensing device 1000 includes an accelerometer 341, an altimeter 342, a humidity sensor 343, a heart rate monitor 344, and a thermometer 345. The dispensing device 1000 also includes a reservoir 320 for a selected fragrance in the fragrance cartridge 410. In operation, sensors on the dispensing device 1000 transmit data to the smart device. The smart device then processes the data and alerts the subject when to reapply the selected fragrance dispensed from the dispensing device 1000.

FIG. 1 is an isometric view of an exemplary dispensing device, in accordance with an embodiment of the present technique. The dispensing device 1000 includes a body 300, a reservoir 320, and a plurality of sensors 340. In the illustrated embodiment, the fragrance cartridge 410 is stored within the reservoir 320. In other embodiments, the selected fragrance 400 may be stored directly in the reservoir 320. In some embodiments, the body 300 of the dispensing device 1000 has a stem 420 thereon. The lever 420 on the body 300 of the dispensing device 1000 may be actuated by the subject 500 to control certain notes of the selected fragrance 400, i.e., the dosage and release rate of the body, floral, etc. of the fragrance.

For simplicity, five sensors are shown in FIG. 1. In different embodiments, the dispensing device may include more or fewer sensors. In some embodiments, the sensors 340 are all placed on the body 300 of the dispensing device 1000. In other embodiments, only some of the plurality of sensors 340 are placed on the body 300 of the dispensing device 1000, while some are carried by the smart device 2000 (not shown in fig. 1). In some embodiments, the dispensing device 1000 includes at least one accelerometer 341, altimeter 342, humidity sensor 343, heart rate monitor 344, and/or thermometer 345. Further, in some embodiments, different sensors may be on the body 300 of the dispensing device 1000 in addition to or instead of those shown in fig. 1. A non-exhaustive list of other sensors 340 includes volatile compound sensors, odor level sensors, sweat sensors, location sensors (e.g., global Positioning System (GPS) sensors), and the like. In some embodiments, a GPS sensor may be used to obtain information about the relative humidity at the location. In other embodiments, the location information obtained from the GPS sensor may be used as a representative of cultural fragrance codes (cultural fragrance norms).

The dispensing device 1000 is communicatively coupled to the smart device 2000 (e.g., wirelessly). In operation, the plurality of sensors 340 on the dispensing device 1000 provide a data stream to the smart device 2000. The smart device 2000 may also have a plurality of sensors 340 thereon. The plurality of sensors 340 on the smart device 2000 may also provide further data streams to the smart device 2000.

A subject (user) may insert a fragrance cartridge 410 containing his or her selected fragrance 400 into the reservoir 320. In some embodiments, the subject may set a desired (target) scent level to be maintained. In some embodiments, the smart device 2000 may also collect data from the plurality of sensors 340 and recommend an optimal scent level. When the scent level falls below the determined target level, the smart device may alert the subject 500. In addition, the smart device may generate a release rate and dose of the selected fragrance 400 to match the target level.

In fig. 1, the smart device 2000 is depicted as a cell phone, however, in other embodiments, the smart device 2000 takes the form of any number of other computing devices, such as a smart watch, tablet computer, or the like.

The dispensing device 1000 may be communicatively coupled to the smart device 2000 via a wireless connection. In some embodiments, the wireless connection is a direct wireless connection, such as a bluetooth connection, a Near Field Communication (NFC) connection, a direct WiFi connection, or any other direct wireless connection. In some embodiments, the wireless connection is an indirect connection via one or more wireless networks, such as a cellular network (e.g., 4G, LTE), a WiFi network, a local area network, any other network, or any combination thereof. In some embodiments, the wireless connection allows the dispensing device 1000 to be located remotely from the smart device 2000.

In some embodiments, the smart device 2000 stores data generated by the plurality of sensors 340 on the dispensing device 1000 and the smart device 2000 for a duration of more than one day. The smart device 2000 may then use this data to analyze trends in the subject's individual odor levels.

Fig. 2A is a schematic view of an exemplary dispensing device 1000. The dispensing device 1000 includes a body 300, a reservoir 320 having a fragrance cartridge 410 therein, a plurality of sensors 340, a dispenser 330, and a plurality of levers 420. In some embodiments, the sensors 340 include at least an accelerometer 341, an altimeter 342, a humidity sensor 343, a heart rate monitor 344, and/or a thermometer 345. Such sensors may be, for example, capacitive (e.g., readings based on changes in electrical capacitance), chemical (e.g., readings indicating changes in electrolyte, metabolite, or ion concentrations), skin pH-based, mechanical, or other sensors. In some embodiments, sensor 340 may constitute an "electronic nose" sensor that indicates a change in sweat composition (e.g., isovaleric acid or volatile steroids such as androstenone, androstenedione, androstenol, etc.).

The fragrance cartridge 410 contains a selected fragrance 400. In some embodiments, the selected fragrance 400 is a solid. In other embodiments, the selected fragrance 400 is a liquid.

Fragrance cartridge 410 is configured to fit within reservoir 320 and connect to dispenser 330. When the subject interacts with the smart device 2000, the dispenser 330 dispenses the selected fragrance 400 in an amount necessary to reach the target fragrance level. In some embodiments, the dispenser 330 is a solenoid-operated sprayer, controlled vent, or other scent-releasing mechanism.

Fig. 2B is a cross-sectional schematic view of an exemplary dispensing device 1000 in accordance with the present techniques. The exemplary dispensing device 1000 includes a body 300 and a fragrance cartridge 410 within a reservoir 320 attached to a dispenser 330. The body 300 of the dispensing device 1000 includes a controller 350, a heater 430 and a battery 440, a sensor 340 and a lever 420. The smart device 2000, communicatively coupled with the controller 350 in the dispensing device 1000, may instruct the controller 350 to release the selected fragrance to match the target level depending on the input of the subject 500. In other embodiments, the controller 350 (e.g., a CPU, digital controller, analog controller, etc.) may be included in the smart device 2000.

In some embodiments, the controller 350 may receive data from the sensors 340, process the data, and send instructions to the dispenser 330. Thus, in some embodiments, the dispensing device 1000 may also function as a smart device, thus eliminating the need for a separate smart device to release fragrance through the dispenser 330.

In some embodiments, the selected fragrance 400 is in the solid phase within the fragrance cartridge 410. In operation, the heater 430 within the dispensing device 1000 may heat the solid selected fragrance 400 into a liquid or vapor phase. In some embodiments, the heater 430 is an electric heater. In other embodiments, the heater may comprise a source of infrared radiation. In some embodiments, the electric heater is powered by one or more batteries 440. In some embodiments, the solid selected fragrance 400 is heated by the heater 430 into a volatile state that can be blown through an outlet into the dispenser 330.

In some embodiments, the controller 350 and dispenser 330 are also powered by the battery 440. In one embodiment, for example, battery 440 is a rechargeable battery configured to receive power from an external source when the potential of rechargeable battery 440 has been depleted. In other embodiments, the battery 440 is a disposable battery.

Fig. 2C is a schematic view of the back of an exemplary dispensing device 1000 in accordance with the present techniques. The dispensing device 1000 includes a body 300 having a stem 420, a plurality of sensors 340, and an attachment mechanism 310. In the illustrated embodiment, the attachment mechanism 310 is a clip for attaching to a garment, such as by clipping the device 1000 to a pocket. In other embodiments, the attachment mechanism 310 may be attached to the subject in another manner (i.e., using a magnet) by sewing the dispensing device 1000 into clothing or the like.

In operation, the dispensing device 1000 may remain attached to the subject's clothing throughout the day, while the sensors 340 on the dispensing device 1000 collect data that is sent to the smart device 2000. In some embodiments, the subject carries multiple dispensing devices such that the sensor 340 can collect data from multiple locations of the subject.

Fig. 3 is an exemplary fragrance cartridge 410 in accordance with the present technology. In some embodiments, the selected fragrance 400 is placed directly in the reservoir 320 of the dispensing device 1000, and in other embodiments, the selected fragrance 400 is contained in a fragrance cartridge 410. The fragrance cartridge 410 may be preloaded with a selected fragrance 400 and may contain information encoded into, for example, a non-volatile computer memory to measure how full the fragrance cartridge 410 is, what fragrance is inside the fragrance cartridge 410, and/or what intensity or dosage is appropriate for a given fragrance 400. In some embodiments, the subject 500 obtains an empty fragrance cartridge 410 and fills it with the selected fragrance of their choice.

In some embodiments, the smart device 2000 reminds the subject 500 throughout the day to dispense more of the selected fragrance 400 to achieve the target scent. In some embodiments, the smart device 2000 also alerts the subject 500 when the fragrance cartridge 410 is low and/or empty.

In some embodiments, the subject 500 treats an empty fragrance cartridge 410 and replaces it with a new fragrance cartridge 410 containing the same or a different selected fragrance 400. In other embodiments, the subject 500 refills the empty fragrance cartridge 410 with the same or a different selected fragrance 400. In some embodiments, the subject 500 may mix multiple selected fragrances 400 in a single fragrance cartridge 410 to further personalize his or her scent.

Fig. 4 is an example of a dispensing device 1000 communicatively coupled to a smart device 2000. In some embodiments, subject 500 has multiple portable dispensing devices 1000 carried by his or her body in different locations. As described above, the dispensing device 1000 may communicate with the smart device 2000 via a wireless connection.

For simplicity, two dispensing devices 1000 are shown, but in other embodiments, additional devices may be communicatively coupled to the smart device 2000. In operation, each dispensing device 1000 may independently collect data via their respective sensors 340. The dispensing device 1000 may be controlled by the smart device 2000 through the controller 350 to dispense fragrance at the same dose and intensity or at different doses and intensities to maintain a desired scent of the subject 500. In some embodiments, the controller 350 is included in the smart device 2000. In operation, the controller 350 may wirelessly send instructions to the dispenser 330 on the dispensing device 1000. In some embodiments, the subject 500 may insert a different selected fragrance 400 into each dispensing device 1000 to further personalize their desired scent. In some embodiments, the plurality of sensors 340 are the same on each of the dispensing devices 1000. In other embodiments, the dispensing device 1000 includes a different set of sensors 340.

The smart device 2000 may store data generated from the plurality of sensors 340 of each of the dispensing devices 1000 individually or together. In some embodiments, the smart device 2000 stores the data generated by each dispensing device 1000 for a predetermined period of time, such as more than one day. The stored data can be used to analyze the subject's 500 personalized flavor levels and preferences. The stored data may also be used to algorithmically predict when a selected fragrance 400 should be dispensed to better suit the body and lifestyle of subject 500. The stored data may also be used to provide advice to subject 500 regarding his or her desired odor level.

Fig. 5 illustrates an exemplary interaction between a subject 500 and a smart device 2000. The smart device 2000 may alert the subject 500 that his or her odor level is below the target odor level. The subject may then choose to apply or reapply their selected fragrance 400 from the dispensing device 1000. The smart device 2000 may also alert the subject 500 of other conditions, such as low or empty of the selected fragrance 400 in the fragrance cartridge 410.

Fig. 6A is an exemplary interface for the smart device 2000 to alert the subject 500 that the odor level is below the target level. For simplicity, the interface is depicted as a reminder icon with a circular button to allow the subject to adjust his or her personal scent. In other embodiments, the interface may consist of different icons or different subject 500 controls. Using the dispensing device 1000 and the plurality of sensors 340 on the smart device 2000, the smart device 2000 alerts the subject 500 to the new condition and enables the subject 500 to correct his or her odor level. For example, the smart device 2000 alerts the subject 500 when the scent of the subject 500 has fallen below a desired or preset scent level.

Fig. 6B illustrates an exemplary interface that allows a subject 500 to control his or her odor level in accordance with the present technology. In operation, the smart device 2000 receives and analyzes data from the plurality of sensors 340 on the dispensing device 1000. The subject 500 may then decide how much of the selected fragrance 400 to dispense, or the subject may decide to follow the recommendations given by the smart device 2000. In some embodiments, after the subject instructs the smart device 2000 to apply more of the selected fragrance 400, the smart device 2000 sends instructions to the controller 350 in the dispensing device 2000 via the wireless connection, the controller 350 causing the dispensing device 1000 to dispense the selected fragrance 400. The controller 350 may include non-volatile memory for storing instructions that, when executed, cause the selected fragrance 400 to be dispensed.

Fig. 7A-7B are example graphs depicting how a subject's personal scent varies over the course of a day without and with the present technology, respectively. The horizontal axis represents time. The vertical axis represents the odor intensity. The area under the horizontal axis represents bad or unpleasant odours. The line below the horizontal time axis ("apparent odor") demarcates the point of intensity of the offensive odor that others can notice. The area above the horizontal time axis represents a good or clean smell. The area directly above the horizontal axis represents an "ideal scent zone" in which the subject's personal scent is pleasant, but not too intense. The area above the ideal scent area represents an area where the subject's personal scent is pleasant but too intense, for example when the subject is using too much perfume or cologne.

Exemplary daily events throughout the day are represented by letters a through I. These exemplary events are: (a) the subject's shower, (B) the subject's use of cologne or perfume, (C) mild physical activity, (D) weather factors such as high temperature and high humidity which affect the subject's personal smell, (E) crowded meetings, (F) social gatherings, (G) moderate physical activity, (H) strenuous physical activity, and (I) the subject's return home in a vehicle. These events show a broad spectrum of activity that may affect the individual scent of a subject, but are not exhaustive, and may occur at any time of the day, not at all, or still other events.

Fig. 7A is an exemplary graph of the individual scent intensity of a subject over an exemplary day without the present technology. First, the subject takes a morning shower (a). This places the subject's scent in the ideal scent zone. The subject then sprayed perfume or cologne (B) from a conventional bottle. This raises the subject's scent to too intense a level. Conventional methods of applying perfumes and colognes do not take into account the individual needs of the subject and do not provide convenient metering to adjust how much fragrance is to be applied. When the subject is performing mild physical activity (C), the conventional perfume or cologne that he or she applies will retain his or her personal odor, keeping it within the desired odor zone. However, external factors that the subject cannot control, in this case (D), high temperature and high humidity, push the subject's personal smell into a bad smell area. When the subject is engaged in crowded meetings (E), social gatherings (F), and performing moderate physical activities (G), his or her odor level stays in the malodorous area, but others have not noticed it. Finally, when the subject is performing strenuous physical activity (H), and the subject returns home via vehicle (I), the subject's odor falls to a noticeable range and is unpleasant.

As previously mentioned, human olfactory adaptation causes users to become smell unaware or at least less sensitive to their own body odor when exposed to them for a period of time. Even if the subject reapplies conventional perfume or cologne at any point in time after (B) on the above-described example day (reapplication is not shown in fig. 7A), the subject does not know when to most effectively apply his or her selected fragrance, what intensity of fragrance to apply, or which external factors (i.e., temperature and humidity) and internal factors (i.e., heart rate and baseline fragrance level) may affect his or her personal fragrance level.

Figure 7B is a graph of the subject's personal odor intensity (also referred to as odor intensity) over the entire sample date using the present technology. In the illustrated embodiment, the subject takes a morning shower (a) placing his or her odor level within the ideal odor zone. Instead of applying a traditional perfume or cologne, the subject turns on the system of the present invention at (B). As the subject works throughout the day, the system maintains the subject's scent within the ideal scent zone, which depends at least in part on the activity performed by the subject, as well as external and internal factors that affect the subject's personal scent. By alerting the subject to his or her personal scent, the subject can adjust the optimal scent level to reach the desired scent zone throughout the day, even if the subject does not notice his or her own scent.
