detailed description

Individuals wash their hair less and less often with a traditional water-based wet shampoo. Several reasons can be given for the decrease in this type of shampoo, such as preventing hair loss and damage to hair, and saving time and energy. The use of dry shampoo is on the rise, and consumers are extending the intervals between salon visits to save money, leading to growing interest in at-home hair and scalp treatments.

In order to cleanse the scalp without a shower or water, it is recommended that the user "smooth" their scalp with their fingers (to move sebum and dirt from the scalp to the hair follicles) and then apply a moisturizer or serum to prevent dryness and/or hair loss. Application of these treatments involves inaccurate dispensing, which can cause excess runoff. Pressing the fingers on the scalp can transfer extra sebum from the fingers onto the scalp and/or make the fingers oilier. Also, dry shampoo is not useful for cleaning the scalp, as it often contains alcohol which can dry out the scalp.

Scalp and scalp treatment formulations are typically applied via pipettes, mousses or powders, and require manual parting of the hair by the user. Powders and mousses are complicated to use because they get on your hands. Also, running excess product onto the scalp can create run-off and make hair look greasy.

Accordingly, there is a need for an improved device which accurately applies a formulation to a user's scalp and/or hair.

Figure 1 through Figure 3 show a portable device 100 (hereafter, a "device") configured to apply a formulation (e.g., scalp treatment or hair treatment), and which has additional functionality through individual activation of bristles and/or teeth for delivery, capture, massage, and/or other uses. In one embodiment, device 100 has a brush- or comb-like architecture configured to provide any number of functionalities, including delivering a formulation to a user's scalp and/or hair, stimulating the scalp of the user, checking contact between the hairs/teeth and the scalp, measuring a degree of hydration of the scalp, applying heat and/or phototherapy to the scalp, curing of the formulation applied to the scalp and/or hair, massaging the scalp, and/or removing excess formulation and/or unwanted particles. Device 100 allows for intuitive action, which provides a familiar gesture that is easy for a user to incorporate into their current beauty and hair care routines.

Device 100 includes a handle 102 comprising a cylindrical body 104. One or more buttons 106a,b located on handle 102 alternate any of the features described herein. This disclosure is not limited to devices 100 having a shape as shown in Figure 1 to Figure 3.

Brush portion 108 is attached to body 104 in the illustrated embodiment; however, in some embodiments, brush portion 108 is removable from body 104, for example, as a modular piece configured to be interchanged with other compatible brush portions and/or comb portions having unique features and characteristics. different features, which are described below. Accordingly, the present disclosure relates to a device 100 comprising a plurality of different modular brush portions 108, each having a different configuration in accordance with any of the embodiments of the present disclosure.

The brush portion 108 has a plurality of bristles or teeth, for example, a bristle 110 disposed on a bristle base 112. Each bristle terminates in a tip 114. The device 100 is shown in a brush configuration in the figures. ; however, this is not limiting. For example, device 100 is configured with a comb configuration in some embodiments, eg, a single row of teeth. Indeed, as used herein, the term "brush portion" includes both brushes and combs. Similarly, the term "hair" includes both "hairs" (of a brush) and "teeth" (of a comb).

As described in detail below, in some embodiments, one or more of the bristles of brush portion 108 are traversed by a fluid conduit configured to deliver a formulation to a user's scalp, and also include a or more of the following features:

• electrically conductive bristles stimulate a user's scalp with a harmless electric current;
• electrically conductive hairs help detect contact between the hairs and the user's scalp by functioning as sensing electrodes, in conjunction with impedance measurement circuitry;
• electrically conductive bristles help determine the degree of hydration of the user's scalp, in conjunction with impedance measurement circuitry;
• electrically conductive bristles provide power (from the device) to one or more electromagnetic energy sources that treat a user's scalp, hair, or formulation applied thereto with thermal energy and/or electromagnetic;
• bristles massage a user's scalp; and or
• bristles help to suction debris and excess formulation from the user's scalp.

Device 100 is configured to removably receive a cartridge of formulation 116 in a receiving portion thereof, for example, a recess disposed in a rear end of body 104. Cartridge 116 contains a formulation, such as a scalp treatment or hair treatment. Said formulation is delivered to one or more of the mouthpieces via one or more fluid conduits extending through the body 104. In one embodiment, the formulation is delivered through the body 104 to the mouthpieces via a formulation dispenser 118, described below.

Device 100 allows a user to easily change cartridges 116, in order to supply different formulations and/or to replace an exhausted formulation. In some embodiments, cartridge 116 is a disposable consumable item that is discarded or recycled after the formulation stored therein is exhausted. In other embodiments, cartridge 116 is refillable. In some embodiments, device 100 is configured to contain a plurality of cartridges 116, each cartridge 116 being filled with a different formulation. Alternatively, the present disclosure relates to methods that include applying a first formulation from a first cartridge 116 and then a different second formulation from a second cartridge 116 as part of a routine scalp or hair treatment.

In some embodiments, cartridge 116 has a product identification tag 120 encoded with instructions for one or more operating parameters of device 100 based on the specific formulation contained in cartridge 116. Accordingly, some embodiments embodiment of the device 100 include a product identification tag reader 122 configured to read the product identification tag 120 and to process the encoded signals into instructions for the operation and control of the device 100 based on the particular formulation (for example, in connection with a control device as described below with respect to Figure 9).

Representative product identification tags 120 include barcodes, QR codes, RFID codes, and the like. Product identification tag 120 is encoded with machine-readable signals that convey device settings for the particular formulation, e.g., any one or more of the following: a formulation dispense time; a formulation droplet size (fine, coarse); a massage ; an application of electric current; an aspiration; pattern formation (eg, flat fan/cone, wide/narrow, solid/hollow, flow/mist); an energy source activation time; and similar.

Formulation dispenser 118 is disposed in body 104 and delivers formulation from cartridge 116 to bristles 110 of brush portion 108, particularly the tips of the bristles. Accordingly, formulation dispenser 118 includes one or more fluid conduits, manifolds, and/or pumps fluidly connecting cartridge 116 to the bristles.

The formulation dispenser 118 is configured to dispense one or more formulations through the tips of the bristles as a fine mist, liquid, and/or any other intermediate form. In one embodiment, formulation dispenser 118 includes a compressor, pump, and/or nebulizer to generate a mist from the formulation. In the case of a pump or compressor, the formulation dispenser 118 causes the air or formulation to flow at a high velocity, which propels the formulation through fluid conduits in the bristles 110 such as described below. In some embodiments, a single centralized formulation dispenser 118 is disposed within body 104 of device 100.

In some embodiments, the formulation dispenser 118 includes a nebulizer that generates a mist or vapor from the formulation and dispenses it through individual bristles. This has the advantages of smooth dispersion of the formulation, reduction of wasted product, and improved coverage control. In some embodiments, the nebulizer is an ultrasonic wave generator that produces a mist from the formulation. Representative ultrasonic wave generators include, for example, vibrating membrane type nebulizers which generate vibration in one or more ultrasonic frequencies (eg, between greater than 20 KHz, such as 1 MHz or greater). In some embodiments, the nebulizer employs a piezoelectric material.

Some embodiments of device 100 include a haptic system 124. Some of these haptic systems include a massage therapy system configured to vibrate one or more of the hairs to stimulate the scalp. In some embodiments, the haptic system 124 includes the bristles 110 or elements thereof, such as one or more piezoelectric or shape memory actuators disposed within or along the bristles, which actuators move the bristles when they are electrically powered by the handle 102.

In some embodiments, device 100 is configured to deliver one or more of heat therapy and/or phototherapy through the hairs to generate heat that treats the scalp and/or hair. either alone or in conjunction with the dispensing of formulations from cartridge 116. Accordingly, some embodiments of device 100 include one or more sources of electromagnetic energy (e.g., an LED, a laser diode, a incandescent, halogen device, or similar energy source) disposed on one or more of the bristles (in particular their tips), in order to deliver thermal energy and/or light energy to the scalp.

Some embodiments of device 100 include a vacuum system 126 having a vacuum generating motor and a manifold. In one embodiment, the vacuum motor is a variable speed motor connected to impeller vanes which enter a flow of air into one or more of the bristles 110 via fluid conduits formed therein. The suction motor enters a flow of air through said ducts, in order to transport and eliminate the used formulation as well as all the debris and sebum from the scalp and hair, which are then collected in the collector. In some embodiments, the manifold has a vent disposed on body 104 of device 100. The vent allows airflow to exit device 100, while used formulation and debris become trapped in the manifold.

The foregoing features and systems are or can be operatively (i.e., electrically) connected to an onboard controller 128, which is described in more detail below.

Additional features of device 100 will become apparent from the details provided below.

Figure 4 through Figure 8 show different embodiments of electrically conductive bristles of the present disclosure. All electrically conductive bristles are configured to be provided on the brush portion of any of the devices described herein (e.g., disposed on bristle base 112 of device 100 of Fig. 1). Additionally, the present disclosure relates to brush portions having a plurality of the bristle structures described herein.

Figure 4 shows a representative conductive hair 410 having an elongated first electrode 430 formed as a first hollow half-cylinder, and a second electrode 432 formed as a hollow half-cylinder contiguous to the first electrode. The first electrode 430 and the second electrode 432 are each made at least partially of an electrically conductive material (for example, a metal such as copper), or are traversed by an electrically conductive path which is formed of a conductive material. Accordingly, the first electrode 430 and the second electrode 432 are configured to electrically connect to a first and a second device voltage source, e.g., pins of the on-board controller, a multiplexer, and/or a control unit. 'feed. When so connected to the device, one of the first electrode 430 and the second electrode 432 is a positive electrode, while the other is a negative electrode.

A thin electrical insulator 434 (e.g., 0.1 mm to 2.0 mm thick) extends the length of bristle 410 and separates first electrode 430 from second electrode 432 such that no of first electrode 430 is in electrical contact with second electrode 432. Insulator 434 is formed of a polymer, ceramic, or similar insulator. In some embodiments, insulator 434 is formed from a dielectric material. To clarify, the first electrode 430 is contiguous with the second electrode 432 despite the presence of the insulator 434 between them. In some embodiments, a plurality of these insulators 434 are employed to separate the first electrode 430 from the second electrode 432. While the illustrated bristle 410 has a cylindrical shape, other embodiments have other elongated shapes, including oblong, rectangular, square, and other polygonal shapes.

Thus, in some embodiments, when a voltage differential is applied across first electrode 430 and second electrode 432 and when a conductive pathway (e.g., a user's scalp, serving as a ground path) electrically connects the two electrodes, an electric current (e.g., on the order of microamperes) flows from the first electrode 430 to the second electrode 432. In other embodiments, the first electrode 430 and the second electrode 432 are configured for use as electrodes for measuring impedance across a user's scalp (e.g., for measuring a degree of scalp hydration and/or for verifying contact between the hair 410 and the scalp of the user), in connection with additional impedance measurement particularities described here. In yet other embodiments, the first electrode 430 and the second electrode 432 are terminals for one or more electrical loads disposed on the hair 410 and powered by the power supply unit, for example, a power source. electromagnetic such as an LED. To clarify, the electrodes of any of the bristles described herein are configured to function as electrodes or terminals for one or more of the features previously described in connection with multiplexing and/or firmware provided in the device and described herein. -below.

In the illustrated embodiment, the hair 410 is not provided with a conductive pathway connecting the first electrode 430 and the second electrode 432. On the contrary, when the hair 410 is placed against the scalp of a user, the scalp itself provides the conductive pathway between the two electrodes. Thus, when the first electrode 430 and the second electrode 432 are electrically connected to first and second voltage sources of the device, an electric current is transmitted through the user's scalp between the first electrode 430 and the second electrode. 432, thus providing a stimulating effect.

The bristle 410 is configured to facilitate the application of one or more formulations to the user's hair and/or scalp. Such formulation is supplied to hair 410 from the device cartridge and delivered through the device formulation dispenser. To transport the formulation to the user's scalp and/or near the user's hair roots, bristle 410 has optional fluid conduits formed therein, having internal fluid conduits and/or apertures formed through an exterior surface. For example, first electrode 430 (i.e., first hollow half cylinder) has first fluid conduits 436 formed therethrough, having openings formed along an exterior surface thereof. Likewise, second electrode 432 has second fluid conduits 438 formed therethrough, having apertures formed along its outer surface.

Apertures 440a,b are respectively formed through an outer circumferential surface (for applying formulation to a user's hair) and through an end cap surface of first electrode 430 (for applying formulation to the scalp and/or roots of a user). The second electrode 432 likewise has similar openings. Such outer circumferential apertures are evenly distributed across the outer circumferential surface in some embodiments, and in other embodiments have a greater aperture density in a localized portion of the outer circumference, for example, near the end cap portion to concentrate the formulation near a user's roots.

In some embodiments:

• bristle 410 is provided with apertures only along the outer circumferential surface or through an end cap surface, but not both;
• the 410 bristle is not provided without any fluid conduits or openings;
• the fluid conduits and the openings are laser cut openings or cast openings;
• the fluid conduits of the first electrode 430 are fluidically separated from the fluid conduits of the second electrode 432. In this way, two different formulations can be delivered to the user's scalp and/or hair.

In some embodiments, the first and/or second electrodes 430, 432, and/or the first and/or second fluid conduits 436, 438 are made of a shape memory or piezoelectric material configured for actuation by a electrical current provided by the device, or have such materials incorporated, to advantageously control a direction of movement of the bristle 410. Such materials include polymer, ceramic, and alloy shape memory materials, and the like.

Figure 5 illustrates another representative bristle 510, which has the features of bristle 410 except as described below.

The 510 bristle has a cylinder-in-cylinder construction. That is, an inner cylinder is disposed within an annular space formed by a larger diameter outer cylinder, for example, in a coaxial configuration. Here, although bristle 510 is shaped like a "cylinder", other similar embodiments have different cross-sectional shapes, including triangular, rectangular, square, or other polygonal shape.

Here, the first electrode 530 is formed as an outer cylinder, and the second electrode 532 is formed as an inner cylinder, and the two are separated by a cylindrical insulator 534.

Bristle 510 is provided with fluid conduits, similar to bristle 410 of Fig. 4. In particular, first electrode 530 is provided with fluid conduits disposed across an outer circumferential surface thereof (e.g., the fluid conduit 536a) and through an end cap surface thereof (eg, fluid conduit 536b). In comparison, the first electrode 530 is only provided with openings through one end surface thereof. In some embodiments, such end cap openings are provided through a perforated flat or domed disc having small openings therethrough (e.g., fluid conduit 536c). In some embodiments, the first electrode fluid conduits 530 are fluidly separated from the second electrode fluid conduits 532.

In some embodiments, the first and/or second electrodes 530/532 and/or their fluid conduits are made of a shape memory or piezoelectric material configured for actuation by an electric current supplied by the device, or have such material incorporated, to advantageously control a direction of movement of the bristle 510. Z (i.e., in the axial direction of the hair and the coil).

Thus, the bristles of Figure 4 and Figure 5 are both configured to apply electrical current to a user's scalp when connected to first and second voltage power sources of the device. Additionally, the bristles are configured for use as electrodes to measure impedance across a user's scalp, in connection with impedance measurement features described herein.

Figure 6 illustrates a bristle 610, which has the features of the bristles of Figure 4 and Figure 5 except as described below.

Bristle 610 is similarly constructed to bristle 410 of Figure 4 in that it has a first electrode 630 formed as a first hollow (annular) half-cylinder, mated to a second electrode 632 formed as a half-cylinder. hollow cylinder (annular). The first electrode 630 and the second electrode 632 are separated by an electrical insulator 634. Similar to the bristle 510 of Figure 5, the bristle 610 has an interior cylinder 640 (which is not an electrode) that fits around the within the annular space formed by the first electrode 630 and the second electrode 632.

First electrode 630 has first fluid conduits 636 formed through and through an outer circumferential surface thereof. Likewise, second electrode 632 has second fluid conduits 638 formed through and through a circumferential outer surface thereof. Inner cylinder 640 has fluid conduits 642 formed on one end tip surface thereof, i.e., to direct formulation to a user's scalp and/or roots. .

Figure 7 illustrates a bristle 710, which has the features of the bristle 510 of Figure 5 except as described below. In particular, bristle 710 has an annular first electrode 730 formed as an outer cylinder, a second electrode 732 formed as an inner cylinder that fits within the annular space formed by first electrode 730, and an insulator 734 inserted between the two electrodes.

A plurality of optional power sources 750a-b are disposed on bristle 710. In particular, power source 750a is disposed on an end cap portion of bristle 710, and is electrically connected to both the first electrode 730 and to the second electrode 732, which function as the positive and negative terminals of the energy sources, or vice versa. Accordingly, the power sources are configured to be powered by the device via the first electrode 730 and the second electrode 732. However, in some embodiments, one or more power sources are not powered via the first electrode. and the second electrode. Typically, the energy sources are electrical charges configured to deliver thermal energy and/or electromagnetic energy (eg, ultraviolet or visible light energy) to the scalp, hair a user, and/or a wording provided thereon. This provides a number of benefits to the user, including soothing heat therapy, stimulation of hair follicles, improved formulation penetration, hardening of formulation applied to scalp and/or hair, as well as other benefits.

Accordingly, each power source is a light emitting diode (LED), laser diode, incandescent device, halogen device, or similar power source. In some embodiments, a plurality of energy sources are provided on the bristle 710, for example, at the end cap portion, and/or disposed around the outer circumferential surface of the first electrode 730 (particularly at a distal end thereof near the end cap portion, as in the case of power source 750b). In some embodiments, power source 750a is configured to be driven in volts or microvolts, for safety purposes and to comply with regulations.

Advantageously, the placement of one or more energy sources at or near the end tip portion of the bristle 710 and the use of the first electrode 730 and the second electrode 732 to drive them confers better performance (especially greater energy intensity at higher power output) than positioning the energy source at the base of the hair or distributing light energy through a d accessing fiber optics from a driver disposed within the body of the device, or distributing thermal energy along a conductive pathway disposed along the hair.

The number, size, and position of power sources 750a-b are representative, and not limiting. Some embodiments include a single power source (e.g., disposed on a bristle end cap portion 710). Some embodiments include two, four or more power sources.

In some embodiments, one or more of the energy sources are LEDs. Such LEDs can be configured to provide light at a single wavelength and/or frequency (for example, a laser LED) or at a range of wavelengths and/or frequencies. In some embodiments, one or more of the energy sources are configured to provide light over a wide range of the electromagnetic spectrum (frequency and/or wavelength). In some embodiments, one or more of the power sources includes one or more Group III-V (GaAs) based LEDs configured to emit electromagnetic radiation at wavelengths in the range from green visible light near infrared.

In some embodiments, one or more of the power sources includes one or more Group III nitride blue LED semiconductor emitters configured to emit electromagnetic radiation at wavelengths in a range from ultraviolet to blue visible light. Energy emitted from the energy source in the foregoing embodiments has been shown to treat scalp conditions, stimulate hair follicle cells, and confer other beneficial effects. For added benefit, in some embodiments, the intensity of energy emitted by one or more of the energy sources is configured to be varied by controlling current from the device.

In some embodiments, the output wavelength of one or more of the power sources includes one or more gallium-indium nitride (GaInN) LEDs that have an output wavelength of approximately 360 at 370nm. In other embodiments, one or more of the energy sources emit electromagnetic energy in a wavelength range from about 200 nm to about 2000 nm, which includes wavelengths in the ultraviolet range (about 350 nm) and the near infrared (about 1200 nm).

The bristle 710 also includes an optional contact sensor 752 disposed on the end cap portion between the first and second electrodes 730, 732 to advantageously verify contact with the scalp. In some embodiments, contact sensor 752 is a dielectric material 752 which allows bristle 710 to act as a dielectric contact sensor (capacitance detector). In some embodiments, contact sensor 752 is a piezoelectric material electrically connected to first and second electrodes 730, 732. The shape and size of contact sensor 752 are representative, and not limiting. For example, in some embodiments, contact sensor 752 is a flat disk. Additionally, some embodiments include more than one contact sensor disposed on an end cap portion. In some embodiments, the contact sensor 752 is a dielectric material formed integrally with the insulator 734 made of the same material.

Figure 8 illustrates a bristle 810, which has features adaptable to any of the foregoing bristles, and which is particularly suitable for use with a haptic system of a device.

A first pair of piezoelectric or shape memory actuators 860a, 806, are disposed (placed or incorporated) along the length of the bristle cylinder 810 at diametrically opposed locations (e.g., along an outer surface of the bristle 810 ). The actuators 860a,b are configured to be actuated one by one to cause an oscillatory movement from side to side with respect to a normative center portion of the hair 810, for example, along an x axis. Hair 810 has an optional second pair of actuators 860c,d disposed at diametrically opposite locations, and ninety degrees apart from actuator 860a,b, so that they can be actuated one at a time to create a side-to-side oscillating motion, such as along a y-axis.

In some embodiments, the actuators are each constructed of a piezoelectric material to produce contractions when powered by the device (eg, when voltage is applied). In this way, side-to-side actuation is possible in both the x and/or y axes.

In some embodiments, the bristle 810 is configured to oscillate along the Z axis, i.e., along the length of the bristle 810. In some of these embodiments, the top end of the bristle 810 ( i.e., the end closest to the device) rests against a piezoelectric or shape-memory coil 862 configured to be actuated by a voltage supplied by the device to cause the bristle 810 to oscillate up and down the low low.

The number and placement of actuators in Figure 8 are representative, and not limiting. Additional configurations are possible, for example with bristles having one, two, three, or five or more of these actuators. Although representative embodiments using piezoelectric and shape memory materials are illustrated, this disclosure includes other configurations. For example, in some embodiments, piezoelectric materials are tubes or are stacked in a configuration that causes up and down vibration. As another example, in some embodiments, shape memory materials are provided in the form of strips configured to cause side-to-side movement, bending, and/or shearing for vibration. in the X and Y axes. In any of the bristles described herein, any combination of one or more piezoelectric or shape memory materials may be used to provide the tips with vibration in one or more axes.

Turning now to Figure 9, a device 900 is shown schematically in order to understand the major systems. Device 900 is representative of device 100 of Figure 1, and is compatible with any of the hair structures depicted herein in Figure 3 through Figure 8. Additionally, device 900 is configured to receive one or more cartridges 902. In some embodiments, device 900 includes cartridge 902.

Device 900 is powered by a power supply unit 904 which, in some embodiments, is an alternating current (AC) power supply unit, such as a common household alternating current that employs an electrical cord (not shown). to power device 900. In other embodiments, power supply unit 904 is a direct current (DC) power supply unit, such as a rechargeable battery configured to be charged by being plugged into a household AC outlet. Device 900 is electrically connected directly or indirectly to any one or more of the systems requiring power, namely, a controller 906, which is itself electrically connected to many other systems of device 900.

The brush portion 908 includes one or more bristles as depicted in Figure 2 to Figure 8. Accordingly, each bristle includes one or more of: a plurality of electrodes 910; an electromagnetic energy source and/or a contact sensor 912; and/or an actuator 914. In some embodiments, the brush portion 908 is a permanent fixture attached to a housing of the device 900; however, in other embodiments, the brush portion 908 is a modular accessory that can be reversibly attached to the housing.

Formulation dispenser 916 is as described above with respect to Figure 1. For example, in some embodiments, formulation dispenser 916 is a nebulizer that delivers formulation from cartridge 902 to the portion of brush 908, and in particular to one or more bristles thereof.

Said debris is collected in a collector (for example, a removable bin), which a user can empty periodically.

A cartridge reader 922, for example, an RFID reader or a near field reader, is disposed in the device 900 near where the device 900 receives the cartridge 902 and is positioned to read information contained in a tag. cartridge product identification number 902, as described above.

To clarify, in some embodiments, portions of the bristles are also part of formulation dispenser 916, haptic system 918, and/or suction system 920.

A controller 906 is operatively connected (eg, electrically connected) to the power supply unit 904, to the brush portion 908 (in particular, to the electrodes and actuators thereof), to the formulation dispenser 916 , the haptic system 918, the suction system 920, and the cartridge reader 922.

Controller 906 includes processor 924 (eg, general processing unit, graphics processing unit, or application-specific integrated circuit); a datastore 926 (a tangible machine-readable storage medium); and a plurality of modules which may be implemented as software logic (eg, executable software code), firmware logic, hardware logic, or various combinations thereof. In some embodiments, controller 906 includes a communications interface having circuitry configured to allow communication with other systems of device 900, including brush portion 908, formulation dispenser 916, haptic system 918, vacuum system 920, cartridge reader 922, remote server, base station, and/or other network element via the Internet, cellular network, RF network, personal area network ( PAN), a local area network, a wide area network, or another network. Accordingly, the communications interface can be configured to communicate using wireless protocols (e.g., WIFI®, WIMAX®, BLUETOOTH®, ZIGBEE®, cellular, infrared, near-field, etc.) and/or or wired protocols (universal serial bus or other serial communications such as RS-234, RJ-45, etc., a parallel communications bus, etc.). In some embodiments, the communications interface includes circuitry configured to initiate a discovery protocol that allows controller 906 and another network element (e.g., cartridge 902 and/or brush portion 908 ) identify each other and exchange control information (eg, a dispense time for the formulation stored in cartridge 902 or some other operating parameter). In one embodiment, the communications interface has circuitry configured to initiate a discovery protocol and to negotiate one or more pre-shared keys.

Datastore 926 is a tangible machine-readable storage medium that includes any mechanism that provides (i.e., stores) information in non-transitory form accessible by a machine (e.g., device 900, telephone intelligent, a computer, a network device, a personal digital assistant, a manufacturing tool, any device with a set of one or more processors, etc.). For example, a machine-readable storage medium includes recordable/non-recordable media (e.g., read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, etc.).

Controller 906 includes a plurality of modules. Each module includes logic that, when executed by processor 924, causes device 900 to perform one or more operations related to the treatment of a user's scalp and/or hair.

Cartridge module 928 identifies information stored within cartridge product identification tag 902, e.g., formulation identification, formulation expiration date, and/or corresponding device settings to the particular formulation, for example any one or more of the following: formulation dispensing time; formulation droplet size (fine, coarse); massaging; application of electric current; suction; pattern formation (eg, flat fan/cone, wide/narrow, solid/hollow, flow/haze); energy source activation time; and similar. Said information is communicated to one or more other modules (namely the formulation module 930) in order to correctly adjust the device settings.

Formulation module 930 operates formulation dispenser 916, for example, in a manner consistent with information stored within cartridge product identification tag 902. For example, formulation module 930 operate one or more nebulizers, ultrasonic wave generators, pumps, and/or drivers of formulation dispenser 916 to deliver formulation from cartridge 902 to one or more bristles of brush portion 908. In some modes of embodiment, formulation module 930 modulates one or more of the following operational parameters: formulation dispense time; formulation dispensing pressure; formulation droplet size (fine, coarse); pattern formation (eg, flat fan/cone, wide/narrow, solid/hollow, flow/haze); and similar. In some embodiments, formulation module 930 receives a signal from contact sensing/hydration measurement module 934 (described below) indicative of the user's scalp impedance, which indicates contact. between the hairs and the scalp. Accordingly, the formulation module 930 starts/stops, or increases/decreases a flow of the formulation based on the received impedance value.

The micro-current module 932 supplies the electrodes 910 with one or more bristles of the brush portion 908, in order to apply an electric current to the scalp of a user. In some embodiments, the micro-current module 932 modulates one or more of the following operational parameters: current value, current duration, and/or the identity of specific hairs applying/receiving electrical current. Regarding this last feature, in some embodiments, the micro-current module 932 energizes different bristles at different times, in order to provide a sensation of stimulation to the user, to transmit current through different portions of the leather scalp, and/or for some other benefit. In some embodiments, the micro-current module 932 applies current between the first electrode and the second electrode of the same hair (or more than one hair). In some embodiments, the micro-current module 932 applies current between a plurality of different hairs (i.e., one hair is a positive electrode, and a second hair is a negative electrode). In some embodiments, microcurrent module 932 receives a signal from contact sensing/hydration measurement module 934 (described below) that causes microcurrent module 932 to start/stop an application. electric current to the user's scalp.

The contact sensing/hydration measurement module 934, in some embodiments, measures an impedance of a user's scalp between a first electrode and a second electrode of a hair (via a return path to the handle ), or between two hairs, for example, when powered by device 900. In embodiments where power supply unit 904 is an AC power supply unit, contact sensing/measurement module Hydration 934 measures impedance. In embodiments where power supply unit 904 is a DC power supply unit, contact sensing/hydration measurement module 934 measures resistance. Accordingly, the term "impedance" is used herein to mean both impedance (in AC embodiments) and resistance (in DC embodiments).

Measuring a user's scalp impedance is useful because it 1) correlates with a level of hydration and 2) indicates contact between one or more hairs and the scalp. Accordingly, in some embodiments, the contact sensing/hydration measurement module 934 provides a diagnosis of the degree of hydration and/or health of the user's scalp based on the measured impedance. . This diagnosis provides useful information to the user, for example, it informs the user if further treatment is recommended. In some embodiments, the contact sensing/hydration measurement module 934 transmits a signal to one or more other modules verifying contact between at least one hair and the scalp, for example, the formulation module 930, the microcurrent module 932, energy therapy module 936, haptic module 938, and/or suction module 940 to enable additional functionality.

In some embodiments, the contact sensing/hydration measurement module 934 is communicatively coupled with one or more contact sensors 912 to determine contact with the scalp. For example, in some embodiments, the contact sensing/hydration measurement module 934 receives a signal from a dielectric contact sensor or piezoelectric sensor disposed on an end cap portion of the hair. , and based on this signal, determines whether there is hair contact with the scalp (or degree of scalp contact).

Energy therapy module 936 operates electromagnetic energy sources 912 disposed on one or more bristles of brush portion 908 to provide a soothing heat treatment, to harden the formulation applied to the scalp and/or user's hair, and/or for another benefit. Energy therapy module 936 is configured to modulate intensity level, "on/off" status, "on" duration, and/or other particulars of one or more electromagnetic energy sources 912. Additionally, some embodiments are configured to emit different patterns of energy, i.e., the energy sources on different bristles are activated. In some embodiments, the activation/deactivation of one or more electromagnetic energy sources 912 is based on a received signal from the contact sensing/hydration measurement module 934 indicative of contact between at least a hair and the user's scalp. In other words, the 912 electromagnetic energy source is not activated unless the signal indicates contact with the scalp.

The haptic module 938 activates/deactivates one or more features of the haptic system 918. For example, in some embodiments, the haptic module 938 activates one or more actuators 914 of the brush portion 908 to cause the bristles to oscillate in va- back and forth along an x, y, and/or z axis. In some embodiments, such movement is configured to massage the scalp of the user, and/or to signal a device parameter (e.g., successful treatment cycle, end of treatment cycle, positive contact with the scalp, a low level of formulation, a low level of battery, etc.). In some embodiments, haptic module 938 activates/deactivates haptic system 918 based on a signal from contact sensing/hydration measurement module 934 (e.g., indicative of positive leather contact). hairy).

The 940 Suction Module activates the 920 Suction System to remove debris, excess formulation, and other matter from the user's scalp. In some embodiments, suction module 940 activates/deactivates suction system 920 based on a signal from contact sensing/hydration measurement module 934 (e.g., indicative of contact positive with the scalp).

An optional multiplexer 942 is operatively connected to controller 906 and brush portion 908 to alternate different features of device 900. By way of example, each module represents an input, brush portion 908 represents the output , and the multiplexer alternates between functions of any of the modules described above. In this way, controller 906 employs the same electrodes 910 to perform a plurality of functions, for example, current application, impedance measurement, and/or formulation application. In another embodiment, multiplexer 942 acts as a demultiplexer, with several of its outputs corresponding to different bristles of brush portion 908. In this way, controller 906 is configured to perform one or more among: applying current to different hairs at different times for improved stimulation effect; measuring impedance between different hairs and/or changing which hairs are fed to measure impedance (between electrodes of the same hair) to determine contact with the scalp over a larger area of the portion brush 908 or to determine an average impedance value over a scalp area; to actuate actuators in different bristles for enhanced massage effect; and/or to deliver different functions to different hairs. For example, in some embodiments, multiplexer 942 allows controller 906 to apply current using hairs A + B, while measuring impedance using hairs C + D, and while simultaneously applying the formulation and vacuuming with hairs A, B, C, and D.

For the sake of clarity, any two or more of the previous modules are configured to operate simultaneously, for an enhanced user experience. For example, in some embodiments, the suction module 940 activates the suction system 920 simultaneously with the activation of the formulation dispenser 916 by the formulation module 930.
