[0027] The foregoing aspects and many associated advantages of the present invention will be more readily appreciated as they are better understood with reference to the detailed description that follows, when taken in conjunction with the accompanying drawings. Detailed description

[0028] Eyelash modifications to change eyelashes include: false eyelashes, in which a fiber is attached to a subject's natural eyelashes; mascara to darken, thicken, to lengthen and define eyelashes; and eyelash extension compositions that can be applied to eyelashes with brush and wand applicators to extend the lash structure beyond its natural tips. Existing approaches for applying compositions to eyelashes are unsatisfactory for various reasons, such as indiscriminate application to the skin or other surface, detachment of the composition from the eyelashes, and uneven distribution of the composition along the lashes. Consequently, there is a need for comprehensively improved approaches to applying compositions to eyelashes, including approaches that ensure accurate and precise application and that configure the lashes for superior adhesion to the composition once applied. This disclosure addresses these and other long-unmet needs in the art.

[0029] Accordingly, in one aspect, the disclosure proposes a device for applying a composition to a set of eyelashes that includes a dispensing system comprising elements for mixing and pumping the composition within the device during use, and an application system comprising elements for heating and extruding the composition from the device at the time of application during use. The device may include intelligent control elements, such as monitoring and control circuitry, to monitor the application process and control the dispensing system, the application system, and other elements to ensure that the composition is applied within a working area that includes the length of an eyelash and, optionally, an extension length that extends beyond the natural tip of the eyelash.The workspace defines a distance, space, or volume within which the composition must be applied to the eyelashes during use of the device.

[0030] Examples of disclosure devices, and examples of elements thereof, are shown in Figures 1, 2, 3, 4, and 5. A device can be configured to include a handle attached to a head, according to at least certain form factors. Although some elements are schematically depicted as being within the handle or the head, it should be understood that these elements and any other element included in an implementation of a device can be moved or rearranged within the device, or within one or more additional spaces or structures that are usable with or otherwise constitute the device, without departing from the scope and spirit of the disclosure.It is important to note that the placement of schematic elements in positions within the handle or head, as shown, as appropriate, is for illustrative purposes only and does not preclude alternative configurations according to embodiments that are expressly contemplated and included in the overall scope of disclosure. Furthermore, although explicit structures for certain device elements may not be expressly shown or described here, it should be understood that... understood that these structures or equivalent structures can be obtained in art and are available to the person skilled in the art seeking to put into practice the aspects of disclosure.

[0031] Furthermore, although the connections between elements of a device may not be explicitly shown in the figures, it should be understood that the elements shown, and any other element of a device implementation, may be interconnected in any number, order, or combination for their function or the function of the device as a whole. The connections may include, but are not limited to, one or more fluid or fluidic connections, one or more functional connections, one or more electrical connections, one or more mechanical or physical connections, one or more communication connections, one or more wired connections, one or more wireless connections, one or more logic connections, one or more wireless electromagnetic connections for wireless charging from a power source, one or more circuitry connections, and the like.For example, one or more connections can be implemented between any two or more elements as listed in Table 1 and as shown in the corresponding figures, for the operation of a device (or for the operation of elements or systems of the device). These connections and any other connections implemented in an embodiment can be used to coordinate the operation of the device elements and facilitate the overall operation of the device during use. This coordination can take place with the use of one or more sensors, computing devices, software applications, control circuitry, and the like, as described in more detail here and as encompassed by their equivalents.

[0032] As shown in Figures 1 and 2, a device (1,3) includes a handle (la, 3a) and a head (1b, 3b). The device (1,3) includes a dispensing system, comprising: a motor (lo, 3o) functionally connected to a power source (Ir, 3r), a mixer (In, 3n) functionally connected to the motor (lo, 3o) and configured to mix a plurality of formulas (2a, 2b, 2c) to produce the composition, and a pump (Ip, 3p) functionally connected to the motor (lo, 3o) and configured to pump the composition through an internal volume of the device (1, 3). The device (1,3) also includes an application system, comprising: a heating element (If, 3f) functionally connected to the power source (Ir, 3r) and configured to heat the composition within the inner volume, and an extruded outlet (If, 3f) fluidly connected to the inner volume for extruding the composition from it.

[0033] The formulas (2a, 2b, 2c) can be mixed before use, during use or after use (for example, for future use), in In some embodiments, the formulas (2a, 2b, 2c) can be combined to form a curable composition and mixed shortly before use so that the composition does not harden within the device. In other embodiments, a portion of the internal volume is used to contain a curable composition after mixing but before extrusion, and this portion can be limited in size so that excess or unused curable composition does not harden within the device. In various embodiments, a composition formed from the mixture of formulas (2a, 2b, 2c) can be heated shortly before being extruded from the device so that the extruded composition is warm or slightly warm and fluid enough to be extruded and applied to the eyelashes.In some embodiments, applying heat to a composition can prevent or delay the hardening of the composition, so that the composition does not harden within the device. In at least some embodiments, the device can be cleaned with water or another solvent to remove unused formula or composition or other debris from the device after use.

[0034] The composition can be produced by mixing a plurality of formulas (2a, 2b, 2c). Although any suitable composition can be applied to the eyelashes with a device, in at least some embodiments, a curable composition can be applied. A curable composition can be produced by mixing a cosmetic resin formula and a curing agent formula, for example, which can optionally be further mixed with a customizable formula.The cosmetic resin formula can create a structure for the filament produced by the composition when applied to the eyelashes; the curing agent formula may include a catalyst that activates crosslinking or another reaction for curing the cosmetic resin formula, and the customizable formula may include a mixture of cosmetic polymers, film-forming agents, and the like, which allow the composition to impart any of a variety of cosmetic benefits to the eyelashes, such as hydration, curling, lengthening, and the like.

[0035] The formulas (2a, 2b, 2c) can be contained within a formula pack 2, as shown by way of example in Figures 1 and 2, as a consumable product for use with the device (1, 3). The formula pack 2 can be reversibly attached to the device (1, 3) and can form connections between the formula adapters (1s, 1t, 1u) of the device (1, 3) and the formula pack adapters (2d, 2e, 2f) of the formula pack 2. These connections can include fluid or fluidic connections that fluidly link the (separate) formulas (2a, 2b, 2c) with corresponding formula adapters of the device to be combined and mixed within the device (1, 3). When one or more formulas from the formula pack 2 are consumed, a new or recharged formula pack 2 can be connected to the device (1,3) for further use of the device (1, 3).

[0036] In various embodiments, the formula pack 2 can be configured for a particular benefit or cosmetic application. For example, a customizable formula (e.g., 2a, 2b, or 2c) of the formula pack 2 can be formulated for a particular texture, volume, stiffness, density, color, or other specific property of the eyelash filament after it has been formed by applying the composition to the eyelashes. In at least some embodiments of the formula pack 2, the curing agent formula (e.g., 2a, 2b, or 2c) and the cosmetic resin formula (e.g., 2a, 2b, or 2c) can be kept constant or substantially constant, and the customizable formula (e.g., 2a, 2b, or 2c) can vary for different uses or benefits provided by using different formula packs 2.For example, the stiffness or structural integrity of the filament formed can be increased or decreased for the production of longer or shorter eyelash filaments by using different formula packages 2, respectively, according to various embodiments.

[0037] With further reference to Figures 1 and 2, in some embodiments, the device (1, 3) comprises a thermal sensor (1kΩ, 3kΩ), such as a thermometer, configured to measure the temperature of the composition within the internal volume of the device (1, 3) for a measured temperature, and circuitry functionally connected to the thermal sensor (1kΩ, 3kΩ) and configured to control a function of the heating element (1kΩ, 3kΩ) for adjusting the temperature of the composition based on the measured temperature and a temperature threshold. The circuitry connected to the thermal sensor can route signals from the thermal sensor (1kΩ, 3kΩ) to the logic circuitry of the device (or a computing device) for the computational determination of whether the measured temperature is within or outside a temperature threshold or range.Based on the comparison, the logic circuitry can transmit signals or electrical current to or through the heating element (If, 3f), from the power supply (Ir, 3r), or may refrain from doing so, to increase or decrease the heating of the composition by the heating element (If, 3f) and control the temperature of the composition. The temperature of the composition maintained by these elements may be specific to a formula curing process or otherwise specific to the composition based on the plurality of formulas.

[0038] In some embodiments, the device (1, 3) includes an accelerometer (I1, 3i), a gyroscope (I1, 3j), or both, functionally connected to the circuitry of the device (1, 3) for the detection of a movement of the device (1, 3), of a orientation of the device (1,3), or both. In some embodiments, the movement, orientation, or both, detected by one or both of these sensors or by one or more other sensors of the device (1,3), can be used by the control circuitry of the device (1,3) to determine the status of a gesture used to apply the composition to the set of eyelashes by the device (1,3). In some embodiments, the status of the gesture is correlated, at least partially with or within a tolerable range of, a movement value, an orientation value, or both, from a set of movement values, a set of orientation values, or both, which collectively constitute the gesture.A specific movement value of the assembly, an orientation value of the assembly, or both, is / are positioned within a workspace defined by a gesture start point and a gesture end point. The workspace defines the area, starting from the base of the eyelashes, for example, within which the extrusion of the composition from the device must apply the composition to the eyelash assembly. If, during the gesture, a user performing the gesture deviates significantly from the gesture defined by the set of movement values, the set of orientation values, or both, the device (1,3) can perform an alert or corrective action.The action may include issuing an alert to the user to pause, stop, resume, or adjust the execution of the gesture; pausing or stopping a function of the device (1, 3) such as mixing, pumping, heating, or extrusion; or adjusting the function of the device (1, 3) to accommodate the user's deviation from optimal application of the composition and maintain the application of the composition within an acceptable accuracy range. The alert may be an audible alert, a haptic or tactile alert, a visual alert, or any combination thereof.

[0039] With further reference to Figures 1 and 2, in some embodiments, the device (1, 3) further comprises: a contact sensor (1g, 3g), a conductance sensor (Ih, 3h), or both, functionally connected to the circuitry of the device (1, 3) and configured to detect the position of the device (1, 3) relative to a facial feature of a subject whose eyelashes are to receive the composition. The position of the device (1, 3) relative to the facial feature is used by the device's circuitry (or a computing device) to determine whether the device (1, 3) is positioned at the starting point of a gesture so that the device (1, 3) is able to apply the composition to all of the subject's eyelashes.For example, the contact sensor (1g, 3g), the conductance sensor (1h, 3h), or both, can be configured to detect contact of one or more contact sensor pins (Id, 3d) with the subject's eyelid or eyelashes, and a signal resulting from this contact can be transmitted from the . The contact sensor circuitry (1g, 3g) is connected to the device's logic circuitry (or a computing device) for computational confirmation of the device's positioning, for example, as it can be used as a prerequisite for mixing, heating, or extruding the composition from the device (1, 3). A sensor can be configured to transmit a small electrical current between two or more contact sensor pins (Id, 3d) upon contact of the pins (Id, 3d) with a substrate; in at least some embodiments, the resulting electrical current from the contact of the pins with the substrate can be measured by the device's circuitry and compared to identified current ranges for determining the electrical resistance of the substrate and confirming the type of substrate in contact (e.g., hair or fibers, skin, etc.).If, based on the sensor data and the result, the substrate in contact with the contact sensor pins (Id, 3d) is the intended substrate (e.g., eyelashes), the device can be configured for use. In this way, the device (1,3) can be configured to prevent the composition from being deposited on a non-target surface, such as skin, eyes, an object, or an inert surface.

[0040] In at least some embodiments, and as shown by way of example in [Fig. 2], a device 3 further comprises an optical system 3v functionally connected to the circuitry of the device 3 for detecting the position of the device 3 relative to a facial feature of the subject. The position of the device 3 relative to the facial feature is used by the device's circuitry (or a computing device) to determine whether or not the device 3 is positioned at the starting point of a gesture to apply the formula to the eyelashes.In some embodiments, the optical system 3v comprises: a light element 3x configured to irradiate the facial feature and an infrared (IR) camera 3w configured to capture an IR image of the facial feature and transmit data from the IR image to the device's circuitry (or to a computing device) to determine, via the circuitry, whether the device 3 is positioned at the starting point of the gesture to apply the composition to the eyelashes. In some embodiments, the light element 3x emits at least red or infrared light, and the infrared camera 3w images the light reflected from the surface of the subject's skin, eyelashes, or eyes.In some embodiments, the optical system 3v can be calibrated for use with a particular subject by entering a calibration mode for device 3, positioning device 3 at the starting point of the gesture, and recording imaging of the subject's skin, eyelashes, or eyes at the starting point of the gesture with the device's memory storage (or a computing device). In some embodiments, the optical system 3v can be calibrated or otherwise configured for use with any one of a variety of subjects on the [unclear - possibly "unclear"]. A calibration or usage database for individuals, groups, or populations. In some embodiments, once calibrated, the optical system can image the subject's skin, eyelashes, or eyes and compare the captured images with the recorded image, with image analysis, to determine if the device 3 is positioned correctly for use. If, based on the optical system data and the result, the device 3 is positioned at the starting position of the gesture, the device 3 can be configured for use. In this way, the device 3 can be configured to avoid deposition of the composition on a non-target surface, such as the skin, eyes, an object, or an inert surface.

[0041] With further reference to Figures 1 and 2, a device (1, 3) may comprise a plurality of conductive hairs (1e, 3c) functionally connected to the power source (Ir, 3r) and configured to carry an electrical charge from the power source (Ir, 3r) and to make contact with the cilia assembly to transfer at least a portion of the electrical charge to the cilia assembly. One or more of the cilia may thus have an electrical or ionic charge, so that the cilia assembly is better able to bind to the composition when the latter is applied to it. In these and other embodiments, the composition may comprise an ionic compound, or a plurality of compounds, which includes a charge or a net charge, respectively, that is opposite or complementary to an ionic charge of the primed cilia fiber.In this way, the ionic compound or plurality of compounds can bind ionically to the primed eyelash fiber, optionally in combination with one or more covalent bonds, to fix the eyelash filament to the eyelashes.

[0042] As shown in [Fig. 3], a printed circuit board 4m of a device 4 may include, among other things, a wireless transceiver 4y. In some embodiments, the wireless transceiver 4y is functionally connected to the circuitry of the device 4 and configured for wireless communication with a computing device 5 comprising circuitry for one or more user interactions with the device 4 by means of the computing device 5. The computing device 5 may be any electronic logic device, but in some embodiments, it may be a mobile phone, tablet, personal computer, smartphone, and the like.Although not shown in Figures 1 and 2, the 4y wireless transceiver can be implemented in the example embodiments of these and other figures in the disclosure, and their equivalents, without departing from the scope and spirit of the disclosure.

[0043] Figure 4 shows an example of a form factor that can be used for implementing a disclosure device. A device 6 can be formed with a brush or rod form factor and can include a handle 6a with a The device includes an on / off control 6z and a head 6b. The head 6b may include a plurality of conductive bristles 6c for priming the lashes to receive the composition, one or more contact sensor pins 6d configured for detecting contact with a surface, a plurality of bristles 6e arranged in a brush configuration for combing the lashes and facilitating the application of the composition during use, and other device elements including a heating element and extruded outlet 6f, a contact sensor with circuitry 6g, and a conductance sensor with circuitry 6h. During use, a user grasps the handle 6a, positions the head 6b so that the conductive bristles 6c or the bristles 6e make contact with the lashes, and activates the device by operating the on / off control 6z.The on / off control 6z may include a button, switch, or similar device for the electronic activation of one or more features of device 6. Once activated, device 6 may perform one or more checks to determine the relative positioning of device 6, begin mixing, pumping and heating the composition, and extrude the composition from the extruded outlet of device 6 to deposit the composition onto the eyelashes.

[0044] Figure 5 shows another example of a form factor for a disclosure device. A device 7 can be configured in a shape that at least partially resembles an eyelash curler. The device 7 can include a handle 7a attached to a head, and the head can include conductive bristles 7c, a contact sensor pin 7d, and bristles 7e arranged in a clip configuration. An optical system 7v can be included and positioned toward an upper portion of the device 7. During use, a user grasps the handle 7a, positions the head so that the conductive bristles 7c or the bristles 7e come into contact with the eyelashes, and activates the device 7 by operating the on / off control 7z. The on / off control 7z can include a button, a switch, or something similar, for the electronic activation of one or more features of the device 7.Once activated, device 7 can perform one or more checks to determine the relative positioning of device 7, begin mixing, pumping and heating the composition, and extrude the composition from the extruded outlet of device 7 to deposit the composition onto the eyelashes.

[0045] In one aspect, the disclosure proposes a kit comprising a disclosure device, a formula or package of disclosure formulas, instructional material for giving instructions on a method of using the device to a user, or any combination thereof.

[0046] In one aspect, the disclosure proposes a method for applying a composition to a set of eyelashes of a subject, the method comprising: the positioning of a A device for applying the composition to the entire lash line at the beginning of a gesture for applying the composition to the entire lash line; activation of the device for activation and execution of the gesture to apply the composition to the entire lash line; and positioning of the device at the end point of the gesture, at which point the device ceases applying the composition to the entire lash line. In various embodiments, the process of applying the composition to the subject's entire lash line may be carried out, at least in part, by providing instructional materials to instruct a user on how to use the device.In some embodiments, the instructional materials are provided to the user as part of a kit, for example, following the purchase of the kit and, optionally, a mail order or other physical delivery of the kit to the user or another individual. In some embodiments, the kit includes the device for applying the composition to the entire lash line, the formula or formula pack, a device repair or modification element, the instructional materials, or any combination thereof.

[0047] Accordingly, as shown in [Fig.8], an example of a method of using 10 a moldable filament application device on eyelashes can include, in step 10a, start; in step 10b, activate the eyelash device; in step 10c, position the eyelash device in the start position of the gesture; in step 10d, perform a gesture to apply the moldable filament to the eyelashes; in step 10e, position the eyelash device in the end position of the gesture; and in step 10of, end.

[0048] In embodiments, the device can perform various operations to aid in the application of the moldable filament onto the eyelashes, as shown by way of example in [Fig. 9]. An example of a method of operating a device for mixing, heating and extruding a moldable filament onto the eyelashes 11 includes, in step 1a1a, start; in step 11b, activating the heat, mixing and distributing elements; in step 11e, mixing a plurality of compositions to form a moldable filament; in step 11d, heating and extruding a moldable filament for application onto the eyelashes; and in step 11f, end.

[0049] In various aspects, the disclosure proposes a method for priming eyelashes for receiving a composition onto them, using a device of the disclosure, as shown by way of example in [Fig. 5]. In some embodiments, the eyelashes can be primed before applying the composition to them to enhance the adhesion of the filament to the eyelashes, as described in more detail here. Such a method 8 can include, in step 8a, starting; in step 8b, activating the eyelash device; in step 8c, positioning the eyelash device in the starting position; and in step 8d, performing a gesture to prime the eyelashes for receiving the filament. moldable; in step 8e, position the eyelash device in the end-of-gesture position; and in step 8f, end. In embodiments, the device may have two or more activation modes, for example, a priming mode (to prime the eyelashes for receiving a composition on them) and an application mode (to apply a composition to a set of eyelashes of a subject).

[0050] In some embodiments, the device can perform various eyelash-priming assistance operations. As shown by way of example in [Fig. 7], an example of a method 9 for operating an eyelash-priming device can include, in step 9a, start; in step 9b, detecting the starting position of the stroke and activating the priming element (e.g., charge-conducting hairs); in step 9c, detecting movement and electrically priming eyelashes during the stroke with the priming element; in step 9d, detecting the ending position of the stroke and deactivating the priming element; and in step 9e, end. In at least some embodiments, at least one of the detection steps 9b, 9c, and 9d can be performed, at least in part, by calculations carried out by a computing device 9f using software compatible with the device ("APPLI"), for example.

[0051] In various aspects, the disclosure proposes the concept of a workspace within which the device can be used to prime eyelashes and apply the composition to the eyelashes. The workspace may include all or part of the length of an eyelash, and in some embodiments, may include an extension length that extends beyond the natural end of an eyelash. The extension length may be quantified as a percentage of the natural eyelash length or simply as a unit of length. In some embodiments, the extension length is a constant or variable percentage over a plurality of eyelashes within a set of eyelashes.

[0052] The extension length can be chosen by the user or the subject, or can be customized for a particular application, for example, for use in art, film, studio work, fashion, or makeup to provide a particular or personalized visual effect. The selection of a particular characteristic of the eyelash filament, such as the extension length, can be carried out at least in part as a result of selecting a virtual representation of the applied eyelash filament, generated by a computing device, before the actual application of the eyelash filament to it. For example, a camera of the device or a computing device can be used to capture an image of the eyelashes without the filament applied to them, and the image used as the basis for generating one or more virtual representations of one or more selectable eyelash filaments, shown as one or more overlays on one or more instances of the image. Selecting an overlay image with a particular extension length or other characteristic can serve as input that signals the device to be configured for the application of the chosen lash filament to the lashes during use.

[0053] With regard to the actual application of the composition, the device undergoes various operating steps in support of the process.
