Title: Cosmetic and skincare applicator

Description:
CLAIM OF PRIORITY UNDER 35 U.S.C § 119 
     The present application for patent claims priority to U.S. Provisional Application No. 63/282,426 entitled “COSMETIC AND SKINCARE APPLICATOR”, filed Nov. 23, 2021. This provisional application is assigned to the assignee hereof and hereby expressly incorporated by reference herein. 
    
    
     FIELD OF THE DISCLOSURE 
     The present disclosure relates generally to cosmetic devices. In particular, but not by way of limitation, the present disclosure relates to systems, methods and apparatuses for an improved cosmetic and skincare applicator for applying a thin layer of atomized cosmetic fluid. 
     DESCRIPTION OF RELATED ART 
     Airbrush makeup was used as early as the 1930&#39;s in Hollywood makeup studios. More widespread use in salons and homes didn&#39;t appear until the 1970&#39;s. During most of this time, the airbrush has retained a somewhat consistent shape and operation with a pen-type format passing compressed air across a venturi and causing a localized pressure reduction. This pulls media from a media reservoir and the high velocity of air atomizes the media and expels it through a nozzle. The amount of atomized media leaving the nozzle can be controlled by a user moving a needle that opens and closes a circular aperture in the nozzle. Different sized needle and nozzle combinations can also influence a spread of atomized media as well as the level of atomization. Air is typically provided from a remote compressor via a hose. One example of a pen-style airbrush is shown in U.S. Pat. No. 8,882,000, assigned to Je Matadi Inc., and incorporated herein by reference. 
     Recently, attempts have been made to combine the compressor and airbrush into a single mobile unit that is easier to use, especially for cosmetic applications. For instance, see TEMPTU Inc.&#39;s U.S. Pat. No. 10,264,868, which includes batteries, a DC motor, and an air pump assembly within a single spraying apparatus.

     DETAILED DESCRIPTION 
     The present disclosure relates generally to a cosmetic airbrush. More specifically, but without limitation, the present disclosure relates to a cosmetic airbrush with a more effective air supply system, nozzle, and integration with sensors and feedback loops to provide more effective and novel cosmetic application. 
     The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. 
     Preliminary note: the flowcharts and block diagrams in the following Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosure. In this regard, some blocks in these flowcharts or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions. 
     Additionally, the flowcharts and block diagrams in the following Figures illustrate the functionality and operation of possible implementations according to various embodiments of the present disclosure. It should be noted that, in some alternative implementations, the functions noted in each block may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. 
     The embodiments described below are not intended to limit the disclosure to the precise form disclosed, nor are they intended to be exhaustive. Rather, the embodiment is presented to provide a description so that others skilled in the art may utilize its teachings. Technology continues to develop, and elements of the described and disclosed embodiments may be replaced by improved and enhanced items. 
     It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure. 
     Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, it will also be understood that when a layer is referred to as being “between” two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items, and may be abbreviated as “/”. 
     It will be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to” another element or layer, it can be directly on, connected, coupled, or adjacent to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to” another element or layer, there are no intervening elements or layers present. Likewise, when light is received or provided “from” one element, it can be received or provided directly from that element or from an intervening element. On the other hand, when light is received or provided “directly from” one element, there are no intervening elements present. 
     Embodiments of the disclosure are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the disclosure should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. Accordingly, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the disclosure. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or the present specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     This disclosure describes a makeup and skincare applicator using a venturi to pull liquid makeup into a nozzle, atomize the makeup, and expel the makeup in a fine high-speed mist. The speed and volume of makeup as well as the level of atomization can be controlled via the applicator and in some embodiments can be controlled via one or more feedback loops based on sensed data such as position and distance relative to a user&#39;s face and/or landmarks of a user&#39;s face. 
       FIG.  1    illustrates an isometric view of the makeup and skincare applicator with a head  102  and body  104  removably coupled together. The makeup and skincare applicator  100 , or applicator  100 , comprises a head  102  and a body  104  that can be separated as shown in  FIG.  3    via rotation of the head  102  relative to the body  104 . In this way different heads and bodies can be interchanged, for instance where different heads are used for different applications, and/or where different bodies have different pumps or different electronics. The head  102  includes a no-mess cap  110 , a reservoir assembly  120 , and a trigger assembly  130 , the details of which will be described further in subsequent figures and paragraphs. The body  104  includes a power assembly  140  (or where sensors are used, a power and sensing assembly  140 ), and although not visible from outside, a pump, battery, and other electronics within a shell of the body  104 . A rear of the body  104  includes a charging port, covered by a protective cover  242  in  FIG.  2   , but visible in  FIG.  15   . The body  104  can also include one or more vents  241  for helping to exhaust thermal energy put off by the pump within the shell of the body  104 . These vents  241  may also double as a loop-coupler for a lanyard or other carrying device. The vents  241  may include air filters. 
       FIG.  3    shows the head and body of the applicator  100  in a partially coupled position, for instance, as might be seen during coupling or decoupling of the head to/from the body. The body  104  includes a keyed coupling assembly  343  seen in  FIG.  4   , that includes various protrusions and recesses that mate with similar structures in a bottom of the head  102  as seen in  FIG.  5   . The coupling assembly  343  allows the head  102  to be lowered onto the keyed coupling assembly  343  in a certain orientation such as seen in  FIG.  3   . The body  104  can include an alignment indicator or line  302  that helps a user know which angle to use when coupling the head  102  to the body  104 . From the position in  FIG.  3   , the user can rotate the head  102 , for instance about 10° or about 20° or about 30° or about 45° into a locking or engaged position as shown in  FIG.  1   . The applicator  102  may not be operable until the head  102  is rotated into the engaged position. This rotation may also involve a camming action that squeezes the head  102  and body  104  together and presses together an air interface between the head  102  and body  104 . For instance, a bottom portion of this interface can be seen in  FIG.  4    and as  708  in  FIG.  7   , and a top of this interface can be seen as  416  in  FIG.  5   . In the illustrated embodiment, the interface can include a male portion  416  and a female portion  708 , though male and female orientations can easily be swapped by one of skill in the art. 
       FIG.  5    illustrates further details of the keyed coupling assembly and its corresponding shapes on the bottom of the head. The keyed coupling assembly  343  can include a circular structure with one or more protrusions  402  and one or more recesses  406  and  404 . The recesses  404  are shaped vertically to allow protrusions  412  in the head  102  to pass the protrusions  402  in the coupling assembly  343  when these structures are aligned. This allows the head  102  to be coupled to the base  104  as well as decoupled. When the protrusions  412  are not aligned with the recesses  404 , neither coupling nor decoupling can occur. This is what is meant by a keyed coupling assembly  343 . The protrusions  412  are shaped to rotatably slide within the recess  406  such that the head  102  can be rotated to some extent. For instance, once the head  102  has been lowered onto the keyed coupling assembly  343 , the head  102  can be rotated into a locked position. The protrusions  412  are each arranged at the same radius from a center of a circle that may be centered on the male portion  416 , though this does not have to be the center of rotation. The protrusions  412  can either extend from a ring structure  414  or from sides of the head  102  via extenders  410 . 
       FIG.  7    shows an embodiment of internals of the body shown in  FIGS.  1 - 5   . A case or shell of the body is hidden in this view to reveal the internals of the body. The body can include a battery  704  and an air pump  702 . The battery  704  can provide power to the air pump  702  via connection to a first circuit board  710 , and can be charged via the charging port  243  (e.g., USB type A or C, lightning, thunderbolt, or other power delivery protocol/connector). In some embodiments, wireless charging of the battery  704  is possible via an induction coil  712  or other inductive charging device. The induction coil  712  or other inductive charging device enables wireless (inductive) charging of the battery  704  when a bottom of the body  104  is arranged in proximity to another induction coil  712  or other inductive charging device. While this embodiment is described as providing power regulation through the first circuit board  710 , in other embodiments power can be directly transferred between components and/or independent power regulation devices. 
     In some embodiments a waterproof coating is added to the first circuit board  710 . 
     Also arranged near the bottom of the body  104  can be a first circuit board  710  (or circuit system comprising one or more boards and/or systems-on-a-chip) that can include power management circuitry for controlling charging and discharging of the battery  704  as well as manage delivery of power to the air pump  702 . This power management circuitry may also manage wireless charging of the battery  704  via the induction coil  712  or other inductive charging device. In an embodiment, the air pump  702  may operate within a pressure range of 12-24 PSI or between 15 and 20 PSI and an air flow range of 5 to 8 LPM. 
     A second circuit board  142  (or circuit system comprising one or more boards and/or systems-on-a-chip), can be part of the power assembly  140 . This second circuit board  142  may include a mechanical connection to a selector  716  (e.g., a button) or other toggle mechanism or may be in electrical communication with the same. The selector  716  is configured to allow a user to power on and off the air pump  702  as well as select between two or more powered modes of the air pump  702  (e.g., different speeds). For instance, the air pump  702  may have a first mode with a first air speed or motor RPM, and a second mode with a second air speed or motor RPM greater than the first. A third mode may be enabled that is configured for clearing the applicator  100  in the event of clogs (e.g., having a third RPM greater than the second mode). In the illustrated embodiment, a single selector  716  toggles between different modes or air speeds of the air pump  704 . However, in other embodiments, multiple selectors could be used or a selector having multiple positions could be used. In other words, any selector may be implemented that allows toggling between two or more modes of the air pump  702  as well as powering on and off of the air pump  702 . If the off mode is counted, then the selector  716  can toggle between three or more modes of the air pump  702 . 
     In some cases, a waterproof coating is added to the second circuit board  142 . 
     The second circuit board  142  can include circuits and/or circuit systems for receiving and interpreting inputs from the selector  716 , and for illuminating one or more LED indicators that help inform a user of the current mode of the air pump  702 . In some embodiments, the power assembly  140  can include one or more sensors, such as a Light Detection and Ranging (LIDAR) sensor  718  and one or more cameras  720 . These can be used in feedback loops with a processor on the second circuit board  142 , a processor within the head  102 , or a remote processor, to carry out automated control of functions within the head  102  and body  104  (e.g., air pump speed, needle position, and/or angle of spray pattern). The second circuit board  142  can be couple to and receive power from the battery  704 . 
     In some cases, a power saving program code is included in the logic of the circuit board and triggers when the system falls below a first threshold (e.g., 15%) of battery charge. When triggered, a first setting is configured to activate a power saving mode which automatically converts the applicator into a single speed device (for 2 speed systems) and uses a flashing light, such as an LED on a power button, for a predefined number of intervals, thereby indicating the applicator needs charging. When the device approaches a second threshold lower than the first (e.g., 7.5%) battery charge level the device may automatically shut off and may flash the light for a predetermined number of intervals when the user attempts to use the device, thereby indicating that the device needs to be charged before it can be used again. 
     In some embodiments, one or more sensors  718 ,  720  can be implemented to aid in a feedback loop for controlling various parameters of operation, such as air pump speed, needle position, and/or angle of spray pattern, to name some non-limiting examples. 
     The air pump  708  is shown with a female portion  708  of an interface that allows air from the body  104  to be transferred to the head  102  without loss of pressure. However, other means of coupling air from the air pump  708  to the head  102  can also be implemented. 
     Although an air pump  702  is shown and described, other means of providing pressurized air to the head can also be provided, for instance pressurized and replaceable canisters of air such as widely available CO 2  canisters. 
       FIG.  8    illustrates a cross section of an embodiment of the head  102  and  FIG.  19    illustrates an isometric view of a cross section of an embodiment of the head  102 . The illustrated head  102  includes a cap  806 , a needle  822  passing through a nozzle  833 , a head control system  802 , a reservoir  804 , and an optional media flow control lever  816 . A ring structure  414  can be shaped to couple with the keyed coupling assembly  343  of the body  104 . The male portion  416  is shaped to couple with the female portion  708  seen in  FIG.  7    and thereby allow the air pump  702  to provide pressurized air to the head  102 . More specifically, pressurized air passes through a passage  808  toward the nozzle  833  and then parallel to the fluid channel  838 , passes through an air constriction component  826  to further increase pressure, and then passes through a tip  831  of the nozzle  833  through an aperture made between the tip of the needle  822  and the tip  831  of the nozzle  833 . When the needle  822  is release into a closed position, this aperture is sealed, and no liquid can escape. The aperture allows media to be pulled from the tip  381  of the nozzle  833  and atomized and propelled. The cap  806  includes a cone shaped chamber  836  into which the atomized media first passes and expands after being expelled from the nozzle  833 . The cone shaped chamber  836  can be shaped to enhance atomization as well as control a spray pattern of the applicator as further discussed relative to  FIG.  10   . The nozzle  833  can have a tapered region  832  near the needle tip  831  that increases a pressure of fluid as it approaches the nozzle tip  831 . Different nozzles  833  can be used with different media, for instance one having a first diameter for atomizing skincare fluids and a second having a second diameter for atomizing makeup and hair fluids, where the second diameter is larger than the first diameter. In other words, larger orifice diameters can be used for more viscous fluids. As such one non-limiting example, the first orifice diameter could be around 0.3 mm while the second orifice diameter could be around 0.4 mm. When implemented, the optional media flow control lever  816  is coupled to the needle  822  and can pull the needle  822  back (to the right in  FIG.  8   ) when the media flow control lever  816  is pulled back. As the needle  822  is pulled back, a donut-shaped aperture opens at the end of the nozzle  833  and when air from the passage  808  passes over the tip of the nozzle, media in the fluid passage  824  is pulled from the tip of the nozzle  833  and atomized in the cone shaped chamber  836 . The fluid passage  824  passes from below the lower portion  810  parallel with the needle  822 , through the air constriction component  826 , and finally through the nozzle  833 , and is thus made up of inner surfaces of three different components. The needle  822  also passes through the fluid passage  824 . 
     The lever  816  can be biased to a closed position, and thus as the lever  816  is released and moves back toward the closed position, the needle  822  correspondingly moves forward and gradually closes off fluid flow from the tip  831  until it makes a tight seal with the end of the needle  822  and cuts of fluid flow. Regardless of the lever  816  and needle  822  position, the airflow through passage  808  and past the tip  831  is regulated by the air pump  702  in the body. Different speeds of the air pump  702  can influence the speed, spread, and atomization of high-speed mist leaving the end of the cap  806 . In other words, the position of the needle  822  influences a rate of fluid pulled from the media reservoir  804  and expelled into the cone shaped volume  836 , while a mode of the air pump  702  also influences the rate of fluid pulled from the media reservoir  804 , but also a density of the atomized mist and an angle of spread of the escaping atomized particles. The optional media flow control lever  816  can include a finger catch, or an upwardly-turned flange at an end of the lever  816 , that enhances a user&#39;s ability to pull back on the lever  816 . 
     In some embodiments, the passage  808  can be primarily tubular with a smooth inner surface. However, in embodiments where turbulent air is desired, the passage  808  can include ripples or a textured inner surface or can even have nonlinear shape such as a spiral or other nonlinear form that breaks up laminar flow. 
     The optional lever  816  can be biased toward a closed position by a spring (not shown). In some cases, a dual spring can be used wherein movement of the lever  816  engages a weaker of the two springs first, and then the stronger of the two springs. In this way, a user can more easily move the lever  816  into an optimal position for spraying and be dissuaded from over-movement of the lever  816  into a fully-open position. In other words, there can be an ideal range of positions for the lever  816  and needle  822 , and a dual spring configuration can help uses to find this optimal range. 
     Liquids and other media can be stored in the media reservoir  804 , which may include one or more side walls that can extend above a top surface of the head  102  to thereby increase a volume of the media reservoir  804 . The side walls may be of varying inclines to accommodate more or less viscous liquids and other media. The media reservoir  804  can include a reservoir lid  812 , and this reservoir lid  812  can rotate on a hinge to allow a user to add media to the media reservoir  804 . The hinge may include a pin to reinforce the hinge and prevent the media reservoir from becoming dislodged from the applicator. The reservoir lid  812  includes a gasket  814  or other sealing structure that helps form a water-tight seal between the reservoir lid  812  and the sidewalls of the media reservoir  804  when the reservoir lid  812  is closed (best seen in  FIG.  12   ). The gasket  814  a seal such that jostling or inverting of the applicator does not cause any loss of media from the media reservoir  804 . A friction fit or snap fit can also help retain the reservoir lid  812  in a closed position. The reservoir lid  812  can also be biased into the closed position shown to thereby reduce the chances that media in the media reservoir  804  can escape during use, accidental dropping, being stored on the applicator&#39;s  100  side, etc. In some embodiments, the reservoir lid  812  can include a transparent window such as the window  1302  shown in  FIG.  13   . The media reservoir  804  can include one or more weep holes  815 , such as the weep hole  815  in a top of the reservoir lid  812  seen in  FIG.  13   . In other embodiments, the one or more weep holes  815  can be arranged through the gasket  814  seen in  FIG.  12   , or the sidewalls of the media reservoir  804 , or a combination of the above. The one or more weep holes  815  allow pressure to remain constant within the media reservoir even as media is depleted. In other words, as media is pulled into the media passage  838  and sprayed out the nozzle  833 , air can be pulled through the weep hole  815  and into the media reservoir  804  to maintain pressure in the media reservoir  804 . This pressure stabilization allows more consistent and accurate dosing of media into a vaporized form. A lower portion  810  of the media reservoir  804  can taper toward an exit orifice  811  that meets with the media passage  838 . Further, the lower portion  810  can be sloped toward a front of the head  102  to enhance fluid flow into the media passage  838  and reduce turbulence that is caused by sharp directional changes in fluid flow. In some ways, the lower portion  810  has a funnel shape that provides gravity-assisted movement of fluid from the media reservoir  804  to the media passage  838 . 
     In some embodiments, the media reservoir  804  can be split into two or more sub-chambers via a dividing wall such that colors or types of fluid can be separated until they are pulled down the lower portion  810  and mixed in the media passage  838 . In some embodiments, each sub-chamber can include a controlled discharge interface to controllably release one or more of the sub-chambers into the media passage  838 . For instance, and assuming that three sub-chambers are used, each with a different shade of cosmetic, one, two, or all three of the controlled discharge interfaces can be opened and to different extents, thereby controlling a mixing of colors to effectuate a desired color of atomized mist expelled from the apparatus. In this way, a single applicator could controllably apply different shades of cosmetic to different portions of a user&#39;s body (e.g., face) in realtime as the applicator is moved across the face (e.g., darker shades at the base and side of the nose and lighter shades along the ridge of the nose). In other embodiments, multiple liquids can be mixed in the media reservoir  804  before use. Mixing can be performed via various methods, including, but not limited to, ‘back bubbling’, a process wherein a user covers the opening in the cap  806  with a finger or other object and pulls back on the optional lever  816  thereby driving air backward through the nozzle and up into the media reservoir  804  to create air bubbles in the media reservoir  804  that turbulently mix the contents therein. 
     An air constriction component  826  can be arranged concentrically around the nozzle  833  and can constrict airflow from the passage  808  before it reaches an end of the nozzle  833 . The air constriction component  826  can be positioned upstream from the tip of the nozzle  833  and can present a smaller area, or diameter, for air to pass through than does the passage  808  and in this way the air constriction component  826  increases air pressure reaching the nozzle  833 .  FIG.  9    shows an embodiment of the air constriction component  926  and this version includes three holes spaced at a radius from a center longitudinal axis of the air constriction component  926 . These holes  927  form an air passage much smaller in area than the area formed just before the air constriction component  926  and this increases the pressure on the downstream side of these holes. In this way the air constriction component  926  increases a pressure at the end of the nozzle effectively increasing the vaporization capability of the applicator for a given air pump RPM.  FIG.  9    represents just an exemplary form of the air constriction component  926  and other constriction shapes and structures can be used in  FIG.  8   . For instance, more than three holes could also be implemented and/or different sized holes could be used. Along these same lines, a porous membrane could even be used so long as the air pressure is increased by the membrane, but not overly so. Alternatively, fewer than three holes could be implemented. Whatever, structure is used to constrict the airflow, the design focus will be on reducing an overall cross section for air to pass through as compared to the passage  808 . 
     The illustrated air constriction component  826 / 926  can thread into the head  102 , for stance, via the male threads  925  illustrated in  FIG.  9   . As illustrated in  FIG.  9   , the air constriction component  926  also includes a second set of threads  927  that various components can rotatingly engage with. The cap  906  can couple to the head via flanges as seen best in  FIG.  21   . 
     A sub-cap  828  can be arranged around at least a distal end of the nozzle  833 , and includes a constriction  830  that helps to further increase pressure at the nozzle  833  tip. 
     In some embodiments, the head control system  802  can include coupling structures for connecting the lever  816  to the needle  822 . In other embodiments, the head control system  802  can include electromechanical structures and control that enhance or supplement action of the lever  816 . For instance, the lever&#39;s  816  motion can be digitized in the head control system  802  and used in combination with feedback from sensors, such as LIDAR and a camera (e.g.,  718  and  720 , respectively) to control operation of the head  102 . For instance, this feedback could be used in a type of ‘autopilot’ scheme where a user&#39;s spraying technique is enhanced by the head control system  802  making automated adjustments based on feedback from the sensors. As just one non-limiting example, regardless of a user&#39;s pulling on the lever  816 , the head control system  802  may close the needle  822  when sensors indicate that the cone of spray is in line with a user&#39;s eyes, mouth, or hair. The head control system  802  may include an optional needle controller  840  configured to control a servo or other electro-mechanical device that can move the needle  822  in response to signals from the head control system  802 . For instance, movement of the optional lever  816  can be translated into movement of the needle  822  through the optional needle controller  840 . Alternatively, the sensors may provide feedback, such that a given lever  816  position may result in differing effects on the needle  822 . For instance, if the sensors indicate that the applicator  100  is too close to a user&#39;s face or other body part, the needle  822  position may not be pulled back as far for a given lever  816  position, and in this way the applicator  100  can compensate for user errors in holding the applicator  100  too close to the face or other body part. In these embodiments, a solenoid or a similar electromechanical device can be controlled to move the needle  822 . Similar feedback can be used to smooth or dampen user inputs, for instance, by making smoother adjustments to needle  822  position than those that would directly correspond to movements of the lever  816 . 
     In another embodiment, the optional control lever  816  can be foregone, and the head control system  802  can solely control the needle  822 , for instance via a solenoid. 
     Whether or not the optional control lever  816  is used, a solenoid or similar electromechanical structure can be arranged in the head control system  802  or in the body. Where a solenoid or similar electro-mechanical structure is arranged in the body, a mechanical link from the body to the needle  822  in the head  802  can move the needle  822 . In some cases, power for this mechanical link can come from the air pump and in others it can come from another electro-mechanical structure, such as, but not limited to a solenoid powered by the battery in the body or another power source. In other cases, a vacuum can be created in the head  102  that moves the needle  822 . 
     Data from the sensors may arrive via optional control line  820  that is configured for coupling to a corresponding data line in the body  104 . Power is provided to the head control system  802  via an optional power line  818 , that may be connected, for instance, to the battery in the body. 
       FIG.  10    illustrates an embodiment of a cap such as the cap  806  seen in  FIG.  8   . The cap  1006  can include an ovular opening  1007  with a center of the ovular opening  1007  offset from the nozzle in a vertical direction. The result of this offset is that the spray pattern is aimed slightly upward from one aligned with a longitudinal axis of the nozzle and needle. Further, the opening  1007  includes a lip  1036  that helps collect drips and prevent them from falling onto a floor or the user—hence the cap  1006  can be referred to as a no-mess cap. The shape of the opening  1007  also helps to capture drips via surface tension and hold them in place to prevent them from falling from the no-mess cap  1006 . 
       FIG.  11    illustrates details of an embodiment of the optional airflow control lever  816  and a recess  817  in the head that the lever can fit into when not pulled back. The recess  817  can include writing, symbols, or other imagery to help a user visually know how much media is being sprayed from the applicator. For instance, as the user pulls back on the lever  816  portions of the words “SOFT” and “HEAVY” can incrementally be revealed behind the lever  816 . 
     Although this disclosure has focused on air-assisted methods of atomizing the media, in other embodiments, piezoelectric pumps can also be used, for instance, where a voltage is applied to a piezoelectric material that is coupled to a media reservoir and where flexing of the piezoelectric material increases pressure in the media reservoir sufficiently to expel one or more atomized particles of media into a larger spray of media that is aimed at a user&#39;s body (e.g., face). 
       FIG.  16    shows a detailed embodiment of a second circuit board, such as the second circuit board shown in  FIG.  7   . The second circuit board  1642  can include a mechanical interface  1644  to a selector  1616 . The mechanical interface  1644  can be in electrical communication with one or more processors  1646  and memory  1648 . The memory  1648  may temporarily store signals from the mechanical interface  1644 , for instance, to determine a desired mode of the air pump through a number of selector  1616  presses within a set period of time. The memory  1648  may also be configured to store processor routines to execute by the one or more processors  1646  in response to signals from the mechanical interface  1644 . The one or more processors  1646  may also be in electrical communication with one or more sensors, such as a LIDAR sensor  1650  and a camera sensor  1652 . The one or more processors  1646  may be configured to analyze data from the LIDAR sensor  1650 , the camera sensor  1652 , and the mechanical interface  1644 . Additionally, the one or more processors  1646  may also use relative position or orientation date (e.g., from one or more gyros or accelerometers) as well as data about needle position. A type of media in the media reservoir may also be taken into consideration (e.g., greater pressure is needed to atomize thicker fluids). All of these inputs may be analyzed to produce control signals that can be sent to the needle controller, such as the needle controller  840  in  FIG.  8   . The one or more processors  1646  may also control the mode or RPM of the air pump. The second circuit board  1642  may also include a wireless antenna  1654  such as but not limited to one operating in the 2-6 GHz region (e.g., BLUETOOTH). In alternate implementations, some or all of the processing done by the one or more processors  1646  may be offloaded to a remote device such as a cell phone, tablet computer, laptop computer, or even cloud-based processing, via wireless communication. For instance, the antenna  1654  could be used to transmit sensor data to a remote computing device that can process the feedback and generate instructions to be sent back to the applicator and passed from the antenna  1654  to a respective component such as a solenoid for controlling the needle or a controller for changing a state of the air pump. Typically, these remote devices can have greater processing resources than those arranged within the applicator, though this may not always be the case. 
     Similarly, sensor data can be transmitted via the antenna  1654  to a remote computing device with a display, such as a cell phone, tablet computer, laptop computer, etc. For instance, the camera can capture an image of a user, especially color and texture, while the LIDAR sensor in combination with the camera can locate shapes of the user&#39;s face or other region of the body. The remote computing device can then be used to display a target cosmetic profile and allow a user to provide inputs to that target, which can then be transmitted back to the applicator and used to control operation of the applicator to effect the target cosmetic profile. For instance, the camera  1652  could take an image of a user&#39;s face, which is then displayed on the remote computing device along with an overlay, or modified by, an image of a desired application of makeup or a hair colorant. The user could then make adjustments to the target profile, for instance altering a tone of blush or foundation used on the cheek area, but maintaining the proposed target profile in other regions of the face. This adjusted target profile could then be transmitted back to the applicator and the user could begin applying foundation, blush, hair colorant, etc. while the applicator adjusts the needle and/or air pump mode in real time to assist the user in achieving the adjusted target profile based on a position and orientation of the applicator as well as a memory of previous layers of makeup or hair product. This is just one example, and those of skill in the art can easily perceive how this feedback and user input can be used to effect numerous semi-automated applications of makeup, skin care product, and hair products. 
     Though two distinct circuit boards have been shown and described, in other embodiments, a single circuit board could be used, or more than two circuit boards. Further, the locations of the one or more circuit boards can be different than that shown in  FIGS.  7  and  16   . The functionality of each of the first and second circuit boards may also be distributed in ways other than as described. For instance, processing of signals from the LIDAR sensor and camera could occur on a circuit board arranged at the bottom of the body, such as below the air pump and battery. Alternatively, processing can be distributed between on-device processing and remote processing, such as one or more processors of a cell phone with a wireless link to the applicator. 
     Implementation of the controls discussed in  FIG.  16    can be seen, for instance, in  FIG.  17   , where a user&#39;s face is shown as well as first and second positions of an applicator, such as the ones discussed throughout this disclosure. The applicator can include one or more sensors such as the illustrated LIDAR sensor  1702  and the illustrated camera  1704 . As the applicator is moved between positions, the LIDAR sensor  1702  can take a reading of two or more distances to the face (e.g., D 1  and D 1 ′ and D 2  and D 2 ′) at different angles to form a data map of the face for each position of the applicator. The data map can be stored in a datastore on a computing device and can use a camera  1704  in conjunction with the LIDAR sensor  1702  to form a more accurate and complete mapping of the face, for instance, by recording subtle textures, colors, and details that may have been missed by the LIDAR sensor  1702 . In other words, data from the camera  1704  can supplement the data map formed by the LIDAR sensor  1702 . Either way, this mapping can be used to control aspects of the applicator such as speed of the air pump, needle position, and angle of spread Ø of the atomized mist that is produced. In an embodiment, a distance to the face can be used to adjust a speed of the air pump to thereby increase a speed of air leaving the applicator when the applicator is further from the face and decrease the air pump speed when the applicator is closer to the face. In another embodiment, the position of the needle can be adjusted to change an amount of media being presented to an end of the nozzle based on a distance of the applicator from the face. The distance to the face at any given time can be a shortest distance that the LIDAR measures, an average distance measured, or a weighted distance of all measurements with measurements toward a center (or low angle relative to an axis of the needle) being more heavily weighted. In other embodiments, the LIDAR and camera may be used to recognize regions of the face and adjust settings of the applicator based on the region of the face being sprayed. For instance, the needle may be pulled back further and more media applied per second when the applicator is deemed to be aiming at the cheeks than when the applicator is deemed to be aiming at the lips, eyes, or hair. In other embodiments, the applicator may have stored in memory therein, a mapping of a target makeup profile and the applicator may adjust its settings based on this profile and the location of the applicator as it is moved around the face (e.g., from position A to position B). A target makeup profile could be one deemed to enhance the beauty of a subject, while in other instances the target makeup profile could be designed to mimic the look of another person. For instance, and especially where layers of foundation or another thick cosmetic can be repeatedly layered, the applicator may not only change skin coloration but the shape of the face via repeated application of layers. In some embodiments, two or more media reservoirs can be used each with its own controlled gate such that one or another color can be applied at a time based on the location of the applicator or mixtures of colors can be applied in differing amounts to create a variety of shades across the face. Along this same vein, one media reservoir could contain makeup while another contains a skin care product and the two can be mixed such that makeup and a skin care product can be sprayed simultaneously and in a controlled ratio. Such is not currently possible, and pre-mixing makeup and a skin care product before pouring the mixture into a classic sprayer may degrade the effectiveness of both, whereas this disclosure combines the two mediums at the last possible moment. 
       FIG.  21    illustrates an exploded view of internal components of a head portion according to one embodiment. In this view, the cap  2106 , sub-cap  2128 , nozzle  2133 , air constriction component  2126 , and needle  2122  have been pulled out from the head through aperture  2130  so that these components are more easily visible. The air constriction component  2126  can include male threads  2125  at a proximal end that thread into female threads inside the aperture  2130  (not visible here). A proximal end of the air constriction component  2126  includes male threads that receiver female threads on an inside of the sub-cap  2128 . In turn, the air constriction component  2126  makes up a portion of the fluid channel (e.g.,  838  in  FIG.  8   ) and the tubular structure performing this role extends out a distal end of the air constriction component  2126  and include female threads that receive male threads  2135  on a proximal end of the nozzle  2133 . The cap  2106  snaps or rotates onto flanges  2150  on the head. In this way, the nozzle  2133  threads into a distal end of the air constriction component  2126 , the sub-cap  2128  threads onto a distal end of the air constriction component  2126 , and this assembly of three components threads into the head via the male threads  2125  on a proximal end of the air constriction component (although other orders of assembly are also envisioned). Finally, the cap  2106  can be coupled to the body with a distal end of the sub-cap  2128 , the nozzle  2133 , and the needle  2122  extending partially out an aperture in the cap  2106 . 
     It should be understood that the liquid and media described throughout this disclosure could be a makeup (e.g., foundation, blush, or a tanning formula), a skin care product, or a hair product (e.g., bleach or highlighter), to name a few non-limiting examples. For instance, a hair product could be applied, with feedback from the sensors, to change a color of a user&#39;s roots, while not spraying other portions of the hair, thereby coloring roots and extending the time between visits to a professional colorist. 
     The applicator, especially the body, may include sound deadening materials to decrease an overall decibel level of the applicator. 
     The methods described in connection with the embodiments disclosed herein may be embodied directly in hardware, in processor-executable code encoded in a non-transitory tangible processor readable storage medium, or in a combination of the two. Referring to  FIG.  18    for example, shown is a block diagram depicting physical components that may be utilized to realize the one or more processors  1646  (and any control of the battery, air pump, or needle generally) according to an exemplary embodiment. As shown, in this embodiment a display portion  1812  and nonvolatile memory  1820  are coupled to a bus  1822  that is also coupled to random access memory (“RAM”)  1824 , a processing portion (which includes N processing components)  1826 , an optional field programmable gate array (FPGA)  1827 , and a transceiver component  1828  that includes N transceivers. Although the components depicted in  FIG.  18    represent physical components,  FIG.  18    is not intended to be a detailed hardware diagram; thus many of the components depicted in  FIG.  18    may be realized by common constructs or distributed among additional physical components. Moreover, it is contemplated that other existing and yet-to-be developed physical components and architectures may be utilized to implement the functional components described with reference to  FIG.  18   . 
     This display portion  1812  generally operates to provide a user interface for a user, and in several implementations, the display is realized by a touchscreen display. The display portion  1812  may also be implemented by one or more LEDs of the same or different colors, or having one or more blinking patterns each representative of a different mode of the air pump or another sub-component of the applicator. In general, the nonvolatile memory  1820  is non-transitory memory that functions to store (e.g., persistently store) data and processor-executable code (including executable code that is associated with effectuating the methods described herein). In some embodiments for example, the nonvolatile memory  1820  includes bootloader code, operating system code, file system code, and non-transitory processor-executable code to facilitate the execution of a method for controlling the applicator in conjunction with human operation, for instance, as shown in  FIG.  17   . 
     In many implementations, the nonvolatile memory  1820  is realized by flash memory (e.g., NAND or ONENAND memory), but it is contemplated that other memory types may be utilized as well. Although it may be possible to execute the code from the nonvolatile memory  1820 , the executable code in the nonvolatile memory is typically loaded into RAM  1824  and executed by one or more of the N processing components in the processing portion  1826 . For instance, the memory  1648  is a non-limiting example of the nonvolatile memory  1820 , though it could also be volatile memory such as RAM  1824 . 
     The N processing components in connection with RAM  1824  generally operate to execute the instructions stored in nonvolatile memory  1820  to enable control of the air pump and/or a servo or other electromechanical device controlling the needle position. For example, non-transitory, processor-executable code to effectuate the methods described with reference to  FIG.  17    may be persistently stored in nonvolatile memory  1820  and executed by the N processing components in connection with RAM  1824 . As one of ordinarily skill in the art will appreciate, the processing portion  1826  may include a video processor, digital signal processor (DSP), micro-controller, graphics processing unit (GPU), or other hardware processing components or combinations of hardware and software processing components (e.g., an FPGA or an FPGA including digital logic processing portions). 
     In addition, or in the alternative, the processing portion  1826  may be configured to effectuate one or more aspects of the methodologies described herein (e.g., the method described with reference to  FIG.  17    or the method for controlling air pump state as described throughout). For example, non-transitory processor-readable instructions may be stored in the nonvolatile memory  1820  or in RAM  1824  and when executed on the processing portion  1826 , cause the processing portion  1826  to control a state of the air pump and/or a position of the needle based on input from the selector  716  and/or the LIDAR  718  and/or the camera  720 . Alternatively, non-transitory FPGA-configuration-instructions may be persistently stored in nonvolatile memory  1820  and accessed by the processing portion  1826  (e.g., during boot up) to configure the hardware-configurable portions of the processing portion  1826  to effectuate the functions of the first or second circuit boards. 
     The input component  1830  operates to receive signals (e.g., a signal from the selector  716 , the LIDAR  718  or the camera  720 ) that are indicative of one or more aspects of the user&#39;s input and/or proximity of the device to different facial features/structures or other portions of a user&#39;s body. The signals received at the input component may include, for example, analogue voltages from the selector  716  or digital signals from an analog-to-digital converter arranged between the sensors  718 ,  720  and the second circuit board  142 . The output component generally operates to provide one or more analog or digital signals to effectuate an operational aspect of the air pump state and/or needle position. For example, the output portion  1832  may provide the air pump control signal described with reference to  FIGS.  7  and  16   . 
     The depicted transceiver component  1828  includes N transceiver chains, which may be used for communicating with external devices via wireless or wireline networks. Each of the N transceiver chains may represent a transceiver associated with a particular communication scheme (e.g., WiFi, Ethernet, Profibus, etc.).
