Summary of the invention

[0003] In one embodiment, the hair treatment system intelligently treats or treats the hair and scalp by area. In one embodiment, a proximity sensor, such as a camera or infrared (IR), or both a camera and an infrared sensor, in combination with a contact sensor, is used to approximate distance and location and generate commands that modify the dispensing or treatment of product along the length of the hair and into the scalp.

[0004] In one embodiment, the hair treatment system facilitates pattern application and treatment dosage (eg, roots and ends of hair) as well as distinguishing the scalp from the hair from the air.

[0005] In one embodiment, the hair treatment system controls the outflow or direction of scalp and hair treatment to minimize waste and inhalable mist.

[0006] In one embodiment, the hair treatment system includes a scalp contact sensor, such as an open or short detector or a dielectric sensor on the bristle tips of a brush or comb, and determines whether the hair treatment system is in contact proximate to the scalp or hair roots.

[0007] In one embodiment, the position on the head (top vs. side) is further calculated by using an accelerometer. The camera and / or IR sensor determines how far the device is from the scalp, whether it is in contact with the hair, and whether it has reached the ends of the hair. Different types of products are dispensed (i.e., through nozzles or jet valves) and / or different types of LEDs are irradiated (i.e., red vs. UV) depending on the different areas on the hair or scalp.

[0008] In one embodiment, an advantage of the present disclosure is to provide a device for dispensing dry shampoo in a cleaner and more accessible form.

[0009] In one embodiment, a cartridge containing a dry shampoo solution is embedded in the applicator device. When activated via an on button, the dry shampoo solution is dispensed in measured amounts via a pump into a series of perforated tips or teeth therein. When the user combs or brushes their hair, the solution slides onto and into the hair.

[0010] In one embodiment, the device releases the hair and scalp product as a vapor cloud (mist) through ultrasound. This has the advantage of gentle dispersion of the product to reduce the amount of waste and improve control of coverage. The solution is contrasted with an aerosol sprayer, which can spray more than needed and produce a large cloud that covers the outer area of ​​the user's head.

[0011] In one embodiment, the multi-use device cooperates with a novel brush or comb tip for dispensing.

[0012] In one embodiment, each tip is constructed as a junction of a semi-cylindrical positive conductor and a semi-cylindrical negative conductor, separated by a non-conductive washer (insulator).

[0013] In one embodiment, each brush (or comb) tip is a cylindrical chamber that is longitudinally divided into two or more chambers that are electrically insulated from each other or two or more coaxial cylinders that are electrically insulated from each other.

[0014] In one embodiment, the tip has a positive terminal that can be used to provide microcurrent to the scalp, where the scalp serves as a ground (GND) path.

[0015] In one embodiment, the brush (or comb) tips can provide microcurrent to the scalp, where the scalp serves as a conduction path between the positive and negative terminals of the different tips.

[0016] In one embodiment, a microcurrent can be applied between multiple tips, with one tip acting as a positive source terminal and another acting as a GND terminal.

[0017] In one embodiment, the impedance between the positive and negative terminals may be measured to determine the scalp moisture level.

[0018] In one embodiment, impedance between multiple tips may be measured to determine scalp moisture levels over a wider area.

[0019] In one embodiment, the impedance between the positive or negative terminal and the scalp (via the return path to the handle) can be measured to determine if the tip is in contact with the scalp (skin). This is useful if the application requires scalp contact; for example, in a preparation treatment and vacuum system, the scalp is the treatment target and the vacuum risks pulling hair if it does not operate directly on the scalp.

[0020] In one embodiment, a light emitting diode (LED) may be placed at the end of the tip and powered by two terminals.

[0021] In one embodiment, depending on the power of the LED, the heat dissipation may be absorbed by the conductive material (heat sink).

[0022] In one embodiment, the LED is placed at the distal end of the tip. In this configuration, the LED can deliver more energy to the scalp than if it were placed at the base of the tip or delivered through a long fiber optic path.

[0023] In one embodiment, the LEDs may be used to process, cure the formulation, or indicate device status (ie, operating mode or charging status).

[0024] In one embodiment, a series of laser cut holes (perforations) along the length of the tip can be used to deliver the formulation to the scalp and hair.

[0025] In one embodiment, if only the scalp is being targeted, a single opening only at the end of the tip may be used.

[0026] In one embodiment, the function of the tip and its separate conductive halves may be controlled by a microprocessor circuit within the body of the brush or comb device.

[0027] In one embodiment, the brush or comb tip is non-conductive and a multi-post structure may be useful if the application involves mixing a formulation or dispensing a formulation and drawing a vacuum to a small controlled target area on the scalp.

[0028] In one embodiment, a portable sized brush or comb device includes massage tips that are individually controlled in XYZ motion by actuators. The tips individually dispense precisely measured volumes of scalp product only when in contact with the scalp (through the use of open / short or dielectric skin contact sensors). The individually activated tips spray hair product (dry shampoo or hair dye) in a tightly controlled pattern (i.e., flat fan pattern). Personalized scalp and hair products are stored in replaceable cartridges. The addition of a camera can determine hair density, tone, and dryness related to scalp and hair conditions. The addition of an LED can further process the hair for camera imaging and for formulation curing.

[0051] Many scalp and hair treatment devices are known. For example, reference may be made to applicant's prior publications 2005 / 0081871, 2014 / 0088522, 2017 / 0150810, 2017 / 0326020, 2019 / 0098977, 2019 / 0209077. According to the present disclosure, devices for treating hair or scalp or both hair and scalp may be improved by including sensors that detect the precise position or proximity of the device relative to the scalp and hair. Devices with such sensors may use this information to control the treatment being delivered.

[0052] According to the present disclosure, sensors are provided so that more "smart" devices can be programmed to adjust treatments based on the location or proximity of a hair treatment device to the scalp or hair, or whether the device is actually in contact with the hair or scalp. Examples of hair and scalp treatment systems include, but are not limited to, scalp massagers, hair dryers, and dispensers for shampoo, bleach, colorant, and other preparations.

[0053] In one embodiment, the hair and scalp treatment system according to the present disclosure is embodied in a handheld electric device. The device shown in the figure is an example of a hair or scalp treatment system. However, previously known hair and scalp treatment devices can also be modified to have the smart functions described herein. For example, Figure 1The device 100a in FIG. 1 shows a relatively large prong that can be used to dispense formulations, act as a vacuum or blower, and provide light and electrostatic treatment. However, in other embodiments, the prong can be replaced by a brush head with bristles or a comb with teeth.

[0054] Individuals are washing their hair less and less frequently with traditional wet water-based shampoos. Some reasons can be given for the decline in this type of shampoo, such as preventing hair loss and hair damage or saving time and energy. Dry shampoos are on the rise. People are trying to extend the time between salon visits to save money, resulting in a growing interest in colored dry shampoos for root touch-ups. Dry shampoos are primarily packaged in spray bottles. However, spray bottles create problems with inhaling the product and accidentally spraying the face (especially the eyes). Spray bottles are not precise in both the direction and amount of spray. In addition, spray bottles are not suitable when traveling or using public bathrooms. Dry shampoos do not clean the scalp and can actually damage the scalp. Despite this, people believe that caring for the scalp will result in healthy hair. The "dry" method of cleaning the scalp involves brushing or combing to apply oils to the hair. Scalp care and scalp guidance formulas can be applied by pipette, foam or powder, and require manually separating your hair. Powders and foams are on hand. Dripping excess product onto the scalp can create hair fall and greasy-looking hair. Reusable and closed-loop product designs are a growing demand.

[0055] The present disclosure relates to a device for cleaning hair, which can be used, for example, with dry shampoo or other preparations. Scalp and hair preparations can be used to treat dandruff, hair loss, stress relief, itching, color and tone, oiliness, appearance, curls, volume, shine, dryness, density, etc. However, there is a need for smarter ways to apply preparations to the scalp and hair.

[0056] In one embodiment, the device uses a brush-like or comb-like structure that relies on a combination of mechanical and chemical actions to deposit the desired formulation for cleansing, remove formulations with unwanted particles, and further provide additional cosmetic or health attributes. The comb-like action provides a familiar gesture that is easily incorporated into current beauty and hair care routines. In addition, the device can include a hollow conductive tip arranged in a brush or comb configuration. The conductive tip allows for several options, for example, the conductive tip can be used with a microcurrent generator, or the conductive tip can be used with an electrostatic charger to charge the scalp or hair with a positive or negative charge that will attract the hair formulation to the charged area.

[0057] In one embodiment, the device is provided with a prong or tip utilizing a hollow structure that allows for more precise delivery of the formulation. In one embodiment, the prong and tip can be used to provide a microcurrent or electrostatic charge to the scalp and hair. In one embodiment, the tip can be used as a contact sensor. In one embodiment, the tip can be used to measure impedance to determine moisture content.

[0058] In one embodiment, the device is shaped into well-known, familiar hair application styles to inspire trust and confidence in the device, resulting in intuitive use and gesture when using the device.

[0059] refer to Figures 1 to 5 , one embodiment of the device 100a includes a handle 104 connected to a generally cylindrical portion 138. The handle 104 is connected to the device 100a at an obtuse angle relative to the front end of the device 100a. The handle 104 helps balance the weight of the device for more comfortable use and easier control. Control buttons can also be located on the handle.

[0060] refer to Figure 3 , on the rear side, the device 100a may include a smaller diameter cylindrical housing 136 that receives a removable cartridge 102 containing a hair or scalp treatment formulation. The cartridge 102 may be configured as a refillable cartridge or a disposable cartridge. In one embodiment, the device 100a may be configured to accommodate more than one cartridge 102, wherein each cartridge may be filled with a different formulation for a different treatment. Alternatively, some applications may use two or more different formulations that require the application of two formulations to achieve the desired effect.

[0061] From the rear housing 136 forward, the outer shape of the device 100a gradually increases to a larger outer diameter portion 138 compared to the diameter of the housing 136. In one embodiment, the device 100a includes a main structure having a generally cylindrical or minimally tapered tapered portion 138 from the rear end to about the middle of the length of the device. In one embodiment, the handle 104 is connected to the rear side of the portion 138. Then, from the proximal side of the cylindrical or minimally tapered portion 138, the device 100a presents a more pronounced conical or decreasing elliptical shape 140 in the top to bottom plane (i.e., viewed from the left or right side) from about the middle of the device 100a to about one-third or one-quarter of the length of the device. However, in the side-to-side plane (i.e., viewed from the top or bottom), the device 100a is not tapered to the extent that it can accommodate three prongs in the side-to-side plane. As described herein, the prongs 108 can be replaced with tips arranged in a brush or comb configuration.

[0062] Then, distal from the smaller end of the cone or oval 140, the device 100a has a transition portion 142 that forms one or more dispensing tines 108 at the front end, such that each tines 108 are separated from the other tines. Although the tines 108 are shown as being connected to a hair or scalp treatment system, the device 100a can be configured as a brush or comb.

[0063] refer to Figure 2 and Figure 5 Each of the prongs 108 has a tapered shape from an initial connection at a transition portion 142 cross section to an end of the prong 108 in both a side-to-side plane and a top-to-bottom plane.

[0064] exist Figure 5 In FIG. 1 , the prong 108 is shown as having a rounded tip when viewed from the bottom (or top) plane. Figure 3 In the embodiment of the present invention, the tip 108 has a flat area or chamfer at the bottom of the tip 108 at the front end when viewed from a side plane, forming a truncated rounded shape. The rounded tip of the tip 108 can separate the hair for better access to the scalp and hair roots. The rounded tip 108 includes "agitation bumps" and chamfers for cleaning and massaging actions.

[0065] exist Figure 5 In one embodiment, the chamfered portion of the tip 108 has an opening 130 for dispensing one or more preparations. In one embodiment, the opening 130 can be static, which means that the spraying or dispensing direction is set and cannot be adjusted. In one embodiment, the opening 130 can be directional, which means that the spraying or dispensing direction can be controlled. For example, the opening 130 can be set on a rotating ball controlled by a microactuator. In one embodiment, multiple openings can be set, wherein each opening is oriented in a different direction, and the preparation is dispensed from the selected opening in a preferred direction.

[0066] In one embodiment, controlling the direction in which the formulation is dispensed also allows the formulation to be applied in a pattern, such as a back-and-forth "bristle stroke" or a circular pattern. In one embodiment, the dispenser 112 can control the form in which the formulation is dispensed. For example, the formulation can be sprayed in patterns of different shapes, such as a flat fan versus a cone, a wide jet versus a narrow jet, a solid jet versus a hollow jet, and a stream versus a mist. In one embodiment, the formulation is dispensed through an adjustable conical nozzle that moves forward and backward around a center rod to adjust the spray pattern.

[0067] In one embodiment, the formulation can be dispensed as a liquid. In one embodiment, the formulation can be atomized and dispensed in the form of a mist. In addition, the chamfered portion of the tip 108 has an opening 132 leading to a vacuum system for collecting the used formulation with any debris or oil removed from the hair. In one embodiment, the opening 132 can be used to supply heated air so that the device 100a can be used as a hair dryer.

[0068] In the illustrated embodiment, each prong 108 is shown as having an opening 130 for dispensing and an opening 132 for vacuuming. However, in one embodiment, there may be dedicated prongs that have only openings for dispensing formulations and dedicated prongs that have only openings for vacuuming. In one embodiment, there may be multiple openings on each prong 108 to provide for dispensing different formulations from the same prong. This may be advantageous when two formulations work together to achieve a desired effect. In one embodiment, each opening may be dedicated to a different formulation. In one embodiment, the device 100a is provided with three prongs 108 for uniform cleaning coverage. The angle of the handle 104 and the length of the prongs 108 allow the user to reach all areas of the scalp and hair.

[0069] In one embodiment, the device 100a includes an electrostatic treatment system. In one embodiment, the purpose of the electrostatic system is to charge a portion of the scalp or hair, or both, by induction or contact. In one embodiment, the electrode 150 is placed at the tip of the prong 108. The electrode 150 can also electrostatically charge the hair preparation droplets as they are dispensed from the opening 130. The charged hair preparation will then be attracted or repelled to the target area of ​​the scalp or hair, depending on the specific charge generated. The electrode 150 is electrically connected to the electrostatic charger. In one embodiment, the electrode 150 can be surrounded by an electrically insulating material. In one embodiment, the device 100a can have multiple hair and scalp treatment systems. The device 100a is also provided with one or more sensors, including contact sensors, proximity sensors, accelerometers, etc. The sensors provide input to the controller, which then controls the output of one or more hair and scalp treatment systems based on the information provided by the sensors.

[0070] refer to Figure 6 , schematically represents device 100a to illustrate the use of sensors in a hair and scalp treatment system. Device 100a may have one or more treatment systems, including but not limited to a formulation dispenser 112, an electrostatic charger 152, a vacuum and collector system 114, a blower and heater system 144, a light treatment system 146, and a tactile vibration massager 158. In one embodiment, device 100a may include the above-mentioned treatment systems, only one treatment system, or a combination of more than one treatment system.

[0071] In one embodiment, the device 100a can be powered by alternating current (AC) or direct current (DC). In one embodiment, the device 100a is powered by ordinary household AC power, which relies on an electrical wire (not shown) to power the device 100a. In one embodiment, the device 100a is powered by DC power, such as a rechargeable battery that can be charged by plugging into a household AC outlet. DC powered device 100a allows the device to be used without having to keep or be near an electrical outlet.

[0072] In one embodiment, the device 100a includes a formulation dispenser 112. In one embodiment, the formulation is stored in a replaceable or refillable cartridge 102. The cartridge 102 can be removed from the device 100a to be refilled or disposed of and replaced with a new, complete cartridge. Once emptied, the cartridge 102 can be replaced with a new cartridge filled with the same or different formulation, or the cartridge can be refilled with the same or different formulation. Figure 1 As shown, cartridge 102 is inserted through the back side of device 100a. Cartridge 102 is connected to supply scalp or hair preparation to dispenser 112. In one embodiment, device 100a can accommodate multiple cartridges, wherein each cartridge is filled with a different preparation that can be dispensed to achieve different treatments and for different areas of the scalp and hair.

[0073] In one embodiment, the cartridge 102 has a product identification label 154 ( Figure 1 ), which product identification tag can convey operating instructions for the device 100a based on the specific formulation contained in the cartridge 102. The device 100a may include a product identification tag reader 156 ( Figure 1 ) which is capable of reading the product identification tag 154 and processing the encoded signal into instructions for operation and control of the device based on the specific formulation. Product identification tags include, for example, bar codes, 2-D bar codes, RFID, etc. The product identification tag is encoded with a machine-readable signal that conveys the device settings for a specific formulation. Different formulations may have different device settings. For example, the product identification tag may include heating or vacuum settings, and dispenser settings from liquid to fine droplets, medium droplets, or coarse droplets. Different formulations may also be used to treat different areas of the scalp and hair. Different formulations may also be used to provide different treatments for the scalp and hair.

[0074] In one embodiment, the product identification tag identifies the formulation in cartridge 102 as containing charged particles, which controls device 100a to turn on electrostatic charger 152, and the product identification tag further determines the electrostatic setting, such as a specific voltage and polarity of negative or positive.

[0075] Dispenser 112 can distribute one or more preparations in the form of fine mist or liquid by prong 108 (or bristles or comb). In one embodiment, dispensing preparation in the form of mist or liquid allows the device to also change the viscosity of the preparation being distributed. In one embodiment, dispenser 112 includes a compressor, a pump or an ultrasonic generator to produce mist from the preparation. In the case of a pump or compressor dispenser 112, this dispenser 112 makes air or preparation flow at high speed, which pushes the preparation through a fine nozzle designed for atomization at opening 130. In the case of a pump or compressor dispenser, a single dispenser 112 can be placed in device 100a. Then, the outlet of the compressor or pump dispenser 112 is guided to each prong 108 by a system of conduits and leaves from the nozzle at opening 130.

[0076] In one embodiment, the dispenser 112 is an ultrasonic jet having an ultrasonic generator in contact with the formulation, wherein the frequency of the ultrasonic waves is sufficient to produce a mist. Ultrasonic jets also include "grid" jets, which have a vibrating grid that just contacts the surface of the formulation to produce a mist. Any form of ultrasonic jet can use a piezoelectric element.

[0077] In one embodiment, the device 100a includes an electrostatic charger 152. The electrostatic charger can generate a positive or negative charge at a target area of ​​the scalp or hair or both. The electrostatic charger 152 is connected to an electrode 150 on the end of one or more prongs 108 via an electrical conductor. Suitable electrodes 150 are electrically conductive and can include, for example, copper, nickel, stainless steel, aluminum, or any alloy thereof. The electrodes 150 can be insulated from the surrounding area by an electrically insulating material (e.g., plastic, elastomer, etc.).

[0078] When the device 100a is operated, the electrostatic charger 152 can generate a positive or negative charge on the scalp or hair or both to attract or repel the agent to the charged area. In one example, the positively charged area is generated by repelling electrons from the area, and in another example, the negatively charged area is generated by attracting electrons to the area. The electrostatic charging can be performed by contact electrical charging, inductive electrical charging, etc. In one example, the electrode 150 is connected to a high voltage source to induce an electrostatic positive or negative charge.

[0079] In another example, the hair formulation is charged as it passes by the charging electrode 150. Negatively charged hair formulation droplets are attracted to a target that may be at a lower potential.

[0080] In one embodiment, the device 100a includes a vacuum system 114 having a vacuum generating motor and a collector. In one embodiment, the motor can be a variable speed motor. The motor induces an air flow to enter through an opening 132 at the tip 108. The air flow can carry the used formulation and any debris and oils rinsed from the hair by the formulation, which are then captured by the collector and the air is exhausted from the device 100a. In one embodiment, the collector includes an annular vent 134 located at the rear of the device 100a and surrounding the barrel 102 ( Figure 4 ). The vent 134 allows air flow to exit the device 100a, while used and debris are captured in the collector. In one embodiment, the collector is removable from the device 100a and is dishwasher safe to allow cleaning in a dishwasher. In one embodiment, the surface of the collector that contacts the used formulation is coated with a hydrophobic or hydrophilic material to facilitate cleaning of the collector.

[0081] In one embodiment, the device 100a includes a blower and heater system 144. In one embodiment, the device 100a can be used as a hair dryer. The blower and heater system 144 can utilize a vacuum motor configured to rotate in opposite directions. When a vacuum is created to draw air through the tip 108, the blower and heater system 144 is configured to blow air out through the tip 108. When operating as a blower, the impeller blades cause the air flow to exit through the opening 132 at the tip 108. Before exiting, the air flow can first pass through the resistive heater coil. The temperature of the air can be increased or decreased by controlling the current applied to the heater coil. The air exhausted at the tip can enter the impeller blades through the annular vent 134 located at the rear of the device 100a.

[0082] In one embodiment, the device 100a includes a light treatment system 146. In one embodiment, the light treatment system includes one or more light emitting diodes 146 (LEDs) that are capable of producing light over a wide range of the electromagnetic spectrum. In one embodiment, light therapy has been used on the scalp to treat skin conditions. In one embodiment, light therapy has been used to stimulate the cells of the hair follicles. However, light therapy has other benefits. In one embodiment, light therapy is performed by light emitting diodes 146 (LEDs) that are capable of producing electromagnetic energy over a wide range of wavelengths (at a single wavelength, such as a laser LED, or at multiple wavelengths over a wide range). For example, the intensity of the light produced by the LED can be varied by controlling the current.

[0083] In one embodiment, LED 146 comprises one or more III-V (GaAs) based LEDs capable of emitting electromagnetic radiation having wavelengths ranging from green visible light to near infrared. In one embodiment, LED 146 comprises one or more III-nitride blue LED solid state emitters capable of emitting electromagnetic radiation having wavelengths ranging from ultraviolet light to blue visible light.

[0084] In one embodiment, the wavelength output of LED 146 includes one or more gallium indium nitride (GaInN) LEDs having a wavelength output of about 360nm-370nm. In other embodiments, LED 146 emits electromagnetic energy in a wavelength range from about 200nm to about 2000nm, which includes wavelengths in the ultraviolet range (about 350nm) and the near infrared range (about 1200nm).

[0085] In one embodiment, the use of different LEDs producing different wavelengths of light may be used to provide different treatments to the scalp and hair.

[0086] In one embodiment, the device 100a includes a haptic system 158. The haptic system can include a vibrating massager. In one embodiment, the haptic vibrating massager can include an electric motor that rotates an eccentrically placed weight that produces vibrations based on the speed of rotation. In one embodiment, the vibrating haptic massager can include an electromagnetic coil and a permanent magnet that produces vibrations based on the cycle of a power supply. In addition, other technologies can be used in the haptic system 158 to produce a type of haptic actuation or sense of impact, including ceramic piezoelectric actuators, shape memory alloys and shape memory polymer actuators, electrostatic forces, electroactive polymer actuators, piezoelectric motor actuators, and pneumatic actuators.

[0087] In one embodiment, the device 100a includes one or more sensors. In one embodiment, the one or more sensors are used to measure one of the device distance, device speed, or device direction relative to the scalp or hair. In one embodiment, speed and direction are used to detect a "brushstroke" technique of moving back and forth. In one embodiment, the device 100a includes a contact sensor 160. The contact sensor 160 can indicate whether the prongs 108, brush, or comb are in physical contact with the skin and hair. In one embodiment, the device 100a includes a proximity sensor 162. The proximity sensor 162 can indicate the distance from the sensor to the surface of the skin and hair. In one embodiment, the contact sensor 160 and the proximity sensor 162 can be placed at or near the tip of one, more than one, or all of the prongs 108 (or bristles or comb teeth). In one embodiment, the device includes one or more accelerometers 164. In one embodiment, the accelerometer 164 is a dual-axis and tri-axis accelerometer that is used to determine the orientation of the device 100a or the position of the device 100a relative to the head and hair. For example, when the device 100a is used on the top of the head instead of the back and the left and right sides, the device 100a is usually held in a different orientation. The dual-axis and tri-axis accelerometers 164 are used to track the orientation of the device 100a, from which the position can be determined. Although the accelerometer 164 is shown on the tip 108, the accelerometer can also be placed anywhere on the device 100a.

[0088] In one embodiment, the contact sensor 160 includes an open circuit or short circuit detector or a dielectric sensor. An open circuit detector may refer to an open circuit detector for detecting a disconnect (open circuit) continuity in electrical transmission. A short circuit detector may refer to the detection of low resistance. A dielectric sensor may also be referred to as a capacitance detector, which can detect changes in dielectric constant. In one embodiment, the contact sensor 160 may be a sensor that detects contact or non-contact of a single prong 108 (or bristle or comb teeth). In one embodiment, the contact sensor 160 may indicate the amount of contact. An example of a contact sensor that can detect the amount of contact is a piezoelectric sensor.

[0089] In one embodiment, the proximity sensor 162 can be an optical sensor, such as an infrared sensor or a camera, or both a camera and an infrared sensor. In one embodiment, the infrared sensor or the camera sensor or both can be positioned at various locations throughout the device 100a. In one embodiment, the camera can be a semiconductor integrated circuit that converts light into an image, such as a charge coupled device (CCD) or a pixel sensor. The infrared sensor detects heat, which is inversely proportional to the distance of the device from the heat source. However, other examples of proximity sensors can also be used, such as capacitive, ultrasonic or Doppler sensors.

[0090] In one embodiment, the accelerometer 164 is used to determine the position of the device 100a (or position relative to the head), the orientation of the device 100a, and the movement of the device 100a. In one embodiment, the accelerometer 164 can be used in conjunction with other sensors, including a geomagnetic sensor (i.e., a compass) and a gyroscope. A gyroscope is a sensor that detects angular velocity around three axes and can detect the rotation of an object. In addition, the geomagnetic sensor can determine the direction that the device 100a is facing.

[0091] In one embodiment, the device 100a includes a controller 148. In one embodiment, the controller 148 is a digital device. The controller 148 may include one or more hardware circuits connected to a printed circuit board, or all circuits may exist on a single chip. The controller 148 may include at least a microprocessor core and a memory. The hardware may be designed for a small manual device. The microprocessor may be implemented as a plurality of processors that work in parallel and serially to execute instructions according to pre-programmed logic.

[0092] The controller 148 receives signals from sensors such as the contact sensor 160, the proximity sensor 162, and the accelerometer 164. The sensors 160, 162, 164 may include circuitry that provides digital signals for storage and processing by the controller 148. In one embodiment, one or more of the sensors may transmit analog signals that are converted to digital signals by analog-to-digital converter circuitry before being stored and processed by the controller 148.

[0093] The controller 148 can perform various operations based on one or more signals provided by the sensors. The controller 148 can also obtain additional information, such as a clock to calculate the passage of time and past data from the sensors.

[0094] The controller 148 converts and interprets the signals from the sensors to represent the spatial conditions of the device 100a, for example, the signals can be interpreted as indicating contact or non-contact with the device 100a, the distance from the device 100a, and the position of the device 100a relative to the scalp and hair. The controller 148 will then execute certain pre-programmed instructions based on one or more signals. The instructions can be encoded in hardware or software. The instructions involve whether and how to change the operation of one or more processing systems based on the signals from the sensors.

[0095] In one embodiment, each treatment system 112, 152, 114, 144, and 146 has a treatment scheme that specifies what treatment should be provided based on the real-time spatial conditions of the device 100a. In this way, the controller 148 sends command signals to the processing systems 112, 152, 114, 144, and 146 to adjust the treatment as the user moves the device 100a to different areas of the scalp and hair. The controller 148 bases its instructions on the current (real-time) detected spatial conditions of the device 100a. The spatial conditions can be related to the contact, distance, and position and orientation of the device 100a to the hair and scalp. The treatment scheme can be provided as any tabular data or function that associates the area or distance to the scalp or hair with the treatment conditions. For example, a hair dryer can be controlled so that the air temperature changes in proportion to the distance of the device 100a from the hair. In such an example, the treatment regimen is air temperature as a function of distance or table data, with the table having a row for each temperature setting and a column for each distance setting, where the intersection of the rows and columns provides the treatment temperature for the spatial condition (distance in this example). Treatment regimens for other treatment devices can be set in a similar manner and based on other spatial conditions.

[0096] The instructions corresponding to each processing scheme can be stored in any type of computer readable medium or computer storage device, and can be stored on and executed by one or more microprocessors. The instructions can be stored in a high-speed memory, such as EEPROM, flash memory, RAM or other programmable non-volatile memory. The instructions can be written in a programming language, such as C, C++, COBOL, JAVA TM , PHP, Perl, HTML, CSS, JavaScript, VBScript, ASPX, Microsoft.NET TM , Go etc.

[0097] Treatment plans for dispenser 112 based on the spatial conditions of device 100a may include, for example, changing the properties of the dispensed formulation from a liquid to a mist depending on whether the formulation is directed at the scalp or into the hair, or changing or stopping the direction of the formulation being sprayed by sensing the position of device 100a relative to the hair or the absence of any hair. Treatment plans also take into account the type of formulation to be dispensed, i.e., whether the formulation is a skin or scalp treatment or a hair treatment. When device 100 holds more than one cartridge, device 100a may be configured to dispense different formulations based on detecting movement of the device from one location to another, where the treatment plan calls for dispensing a different formulation at the second location.

[0098] The treatment scheme of the electrostatic charger 152 based on the spatial condition of the device 100a may include changing the electrostatic parameters based on whether the device 100a is in contact with the scalp (skin) or hair or within a maximum distance relative to the scalp (skin) or hair.

[0099] Treatment of the vacuum 114 based on the spatial conditions of the device 100a may include decreasing the force of the vacuum based on contact with the skin or scalp and increasing the vacuum as the device 100a moves away from the skin or scalp.

[0100] Treatment schemes for blower heater 144 based on spatial conditions of device 100a may include decreasing the force and temperature of the air based on contact with the skin or scalp, and increasing the force and temperature as device 100a moves away from the skin or scalp.

[0101] The processing scheme of the light system 146 based on the spatial conditions of the device 100a can include turning on certain light therapies based on contact with the skin or contact with the hair, increasing or decreasing the power of the light therapy based on distance, or turning off the light therapy when there is no contact or the distance is exceeded where the light therapy is ineffective. In one embodiment, different light emitting diodes can be illuminated based on detecting that the device is moved from one position to another, and the processing scheme calls for different LEDs based on the second position.

[0102] Figure 7 is a flow chart illustrating one embodiment of the operation of the device 100a to change or adjust the operation of the hair or scalp treatment system based on the spatial conditions of the device 100a.

[0103] In one embodiment, in start block 702, device 100a may turn itself on when device 100a detects that it has been picked up by a user via a signal from accelerometer 164. From block 702, the device proceeds to block 704.

[0104] In one embodiment, when the device 100a is used for more than one process, that is, the device 100a has more than one processing system 112, 152, 114, 144, 146, the user can select the processing system in block 702. If the device 100a has a single processing system, block 702 can be omitted. From block 704, the device 100a proceeds to block 706.

[0105] In box 706, the device 100a reads a treatment regimen based on the selected treatment system. Here, "reading" can refer to accessing or storing a treatment regimen in a manner that can be used by the controller 148. The treatment regimen can be stored in a memory of the controller 148. The treatment regimen specifies the treatment delivered by the treatment system based on the changing spatial conditions of the device. The spatial conditions can refer to one or more conditions indicating contact or non-contact with the device 100a, the distance from the device 100a, and the position of the device 100a relative to the scalp and hair. The processing system 112, 152, 114, 144, 146 can change the treatment delivered by the processing system in real time based on the device 100a contact, the device 100a distance, and the position of the device 100a relative to the scalp or hair. From box 706, the device enters box 708.

[0106] In block 708, the device 100a receives sensor data in real time and interprets the data to determine the spatial condition of the device 100a. For example, the spatial conditions that can be determined from the sensors include: contact or non-contact with the device 100a, the distance of the device 100a to the scalp and hair, and the position of the device 100a relative to the scalp or hair. From block 708, the device 100a proceeds to block 710.

[0107] In block 710 , the device 100a compares the current spatial conditions of the device 100a with the pre-programmed treatment protocols. From block 710 , the device 100a proceeds to block 712 .

[0108] In block 712, the device 100a adjusts the treatment system according to the treatment regimen for the current spatial conditions of the device 100a. For example, if the selected treatment system is the formulation dispenser 112, the treatment regimen for the dispenser 112 may use different settings or formulations for contacting the scalp (for the roots of the hair), and use different dispensing settings or formulations where the device 100a moves farther from the scalp. For example, when the device 100a is in contact with the scalp, the formulation may be dispensed as a liquid, and as the distance from the scalp increases, the dispenser 112 reduces the amount or applies the formulation as a finer and finer mist. When contact with the scalp is detected, the treatment regimen for the blower and heater 144 may require minimum heat and airflow settings, and the treatment regimen may require that the temperature and airflow gradually increase as the distance of the device 100a from the scalp or hair increases. The regimen for the light treatment system 146 may require that the LEDs be turned on only when the device 100a is in contact with the scalp, and turned off if there is no contact or the distance increases beyond the effective range of the light treatment. The treatment scheme for the LEDs may require illuminating LEDs of different wavelengths depending on the area of ​​the scalp detected by the device. The instructions to change the treatment system come from the controller 148 which is in communication with each treatment system.

[0109] When the device 100a is set to shut down, for example, when no movement is detected for a predetermined amount of time as determined by the accelerometer, the device 100a may be powered down or placed in a standby mode.

[0110] The use of the device 100a has minimal impact on the hairstyle, and the overall shape of the device 100a is familiar to other hair applications (such as hair dryers), resulting in simple and intuitive use of the device 100a. In addition, the device 100a does not require the hands to contact the hair preparation. The device 100a adds features that make operation easier, and adapting the treatment to the specific spatial location of the device will minimize waste and avoid dispersing mist into the air where it may be inhaled.

In one embodiment, tip 602,1702,1100 and 1200 have a cavity extending the entire length of tip. Tip 602,1702,1100 and 1200 are at least one diameter in length. However, tip 602,1702,1100 and 1200 can be configured as several diameters in length, so the ratio of width to length can be changed from 1 to 1 to 20 or more. Tip 602,1702,1100 and 1200 can be flexible or non-flexible. Separation chamber allows one or more preparations to be transported by each chamber without mixing. Preparations can be separated in corresponding chambers until the preparation leaves the chamber. The distribution of preparations can be realized by configuring each chamber to have an opening along the length of the chamber or only at the end of the chamber or along the length and end of the chamber.

[0117] In one embodiment, the chambers are depicted as half cylinders and full cylinders, but the chambers can have any cross-sectional shape. In addition, in one embodiment, the tips 602, 1702, 1100, 1200 and the first and second cavities forming them can be conductive, thereby being configured as positive and negative terminals to further provide microcurrent or electrostatic charging treatment to the scalp and hair. In addition, the conductive tips 602, 1702, 1100, 1200 have other uses when the first and second cavities are connected to the positive and negative terminals of a power source or the first and second cavities are connected to the positive and negative sensing terminals.

[0118] In one embodiment, the tips 602, 1702, 1100, 1200 need not be conductive, but if the application involves mixing or dispensing a formulation and vacuuming it to a small controlled target area on the scalp, a multi-post structure may still be useful.

[0119] refer to Fig.11In one embodiment, the tip 602 is configured to connect the first hollow semi-cylinder 604 to the second hollow semi-cylinder 606 along the length direction.

In one embodiment, the first semi-cylinder 604 and the second semi-cylinder 606 are separated by an electrical insulator 608. Here, although the overall shape of the tip 602 is a "cylinder", according to the present disclosure, the tip 602 can have any cross-sectional shape, including an ellipse, a rectangle, a square, or any other polygon.

[0120] Fig.11 It is further illustrated that the tip 602 can have an opening 904 on the periphery. The hollow half-cylinder 604 has a first opening 904 along the length of the exterior, and the hollow half-cylinder 606 has a second opening 906 along the length of the exterior. In one embodiment, the openings 904, 906 can be formed by laser cutting holes (perforations) along the length of the tip 602.

[0121] In one embodiment, the tip 602 may omit openings along the length of the tip, and the tip 602 is provided with an opening only at its end, so as to use the tip 602 for scalp treatment. In this way, two different preparations may be delivered from the tip 602 via the half cylinder 604 and the half cylinder 606.

[0122] In one embodiment, the end of the tip 602 comprises a perforated flat or domed disk having a small opening 610 in the first half cylinder 604 and an opening 612 in the second half cylinder 606. In one embodiment, unlike the disk, the half cylinders 604 and 606 may be completely open at the end. Either structure allows the formulation to be dispensed from the end or along the length of the tip 602 or along both the length and the end of the tip.

[0123] In one embodiment, the first hollow half cylinder 604 and the second hollow half cylinder 606 are made of a conductive material such as metal. In one embodiment, one of the first half cylinder 604 or the second half cylinder 606 will be designated as a positive conductor terminal, while the other half cylinder is designated as a negative conductor terminal.

[0124] In one embodiment, the first cavity 604 and the second cavity 606 are made of, or may be embedded with, a shape memory material or a piezoelectric material, which may be actuated by an electric current to control the direction of movement of the tip 602 .

In one embodiment, the first cylinder 1704 is coaxial with the second cylinder 1706. The first cylinder 1704 can be referred to as an inner cylinder, and the second cylinder 1706 can be referred to as an outer cylinder. Here, although the tip 1702 is in the shape of a "cylinder", according to the present disclosure, the tip can have any cross-sectional shape, including an ellipse, a rectangle, a square, or any other polygon.

[0126] In one embodiment, the first cylinder 1704 and the second cylinder 1706 are made of a conductive material such as a metal. In one embodiment, the exterior of the first smaller cylinder 1704 may be coated with an insulator. The insulator is optional if the first cylinder 1704 and the second cylinder 1706 cannot be electrically insulated from each other. In one embodiment, one of the first cylinder 1704 or the second cylinder 1706 will be designated as the positive conductor terminal, while the other cylinder will be designated as the negative conductor terminal.

[0127] In one embodiment, the first cavity 1704 and the second cavity 1706 are made of, or may be embedded with, a shape memory material or a piezoelectric material, which may be actuated by an electric current to control the direction of movement of the tip 1702 .

For example, these materials can exist in the form of polymers, ceramics, and alloys. In one embodiment, the shape memory material and the piezoelectric material can be manufactured as a coil and do not necessarily have to be a cavity. The coil can effectively actuate the tip vertically along the Z axis (i.e., in the axial direction of the coil). The electrical actuation of the shape memory material and the piezoelectric material is performed via an AC or DC power supply having positive and negative terminals connected to the shape memory material or the piezoelectric material.

[0129] exist Fig.121706; however, the opening 1004 may be connected through the outer cylinder 1706 such that the opening is closed to the outer cylinder 1704, for example, by a tube leading to the inner cylinder 1704. The outer cylinder 1706 has a second opening 1006 along the length of the outer portion, wherein the opening 1006 is connected only to the interior of the outer cylinder 1706. In an embodiment, the inner cylinder 1704 and the outer cylinder 1706 are not coaxial with each other, however, the inner cylinder 1704 may be placed against the inner wall of the outer cylinder 1706, and therefore, the opening from the inner cylinder 1704 may only need to pass through the wall of the outer cylinder 1706, thereby avoiding the need to connect the opening via a tube. An insulator may need to be interposed between the inner cylinder 1704 and the outer cylinder 1706 cylinder for electrical insulation. In either configuration, two different agents may be delivered from tip 1702 via inner cylinder 1704 and outer cylinder 1706 .

[0130] In one embodiment, the openings 1004 , 1006 may be formed by laser cutting holes (perforations) along the length of the tip 1702 .

In one embodiment, unlike the disks, the inner cylinder 1704 and the outer cylinder 1706 may be completely open at the ends. Either structure allows the formulation to be dispensed from the end or along the length of the tip 1702 or along both the length and the end of the tip.

An electrically insulating material or coating may be added between the first hollow half-cylinder 1104 and the second hollow half-cylinder 1106 for electrical isolation. A power source is connected to the first half-cylinder 1104 and the second half-cylinder 1106. In one embodiment, this allows one or more light emitting diodes 1102 to be placed at the end of the tip or other location powered by the two half-cylinders acting as terminals through contact with the positive and negative terminals.

[0134] Fig.14 A tip 1200 is shown, which is similar in structure to the tip 1702, made of a conductive first hollow inner cylinder 1204 placed within or coaxially within a conductive second hollow outer cylinder 1206, wherein the first inner cylinder 1204 is the positive or negative terminal and the second outer cylinder 1106 is the terminal of opposite polarity to the first cylinder 1204. An electrically insulating material or coating may be added between the first hollow cylinder 1204 and the second hollow cylinder 1206 for electrical isolation. A power source is connected to the first inner cylinder 1204 and the second outer cylinder 1206. In one embodiment, this allows one or more light emitting diodes 1202 to be placed at the end of the tip or other location powered by the two cylinders acting as terminals through contact with the positive and negative terminals.

[0135] In one embodiment, depending on the power of LEDs 1102 and 1202, the heat dissipation may be absorbed (dissipated) by the conductive material of pillars 1104, 1106, 1204, and 1206.

[0136] In one embodiment, when LEDs 1102 and 1202 are placed at the end of the tip, the LEDs can deliver more energy to the scalp than when placed at the bottom of the tip or when the LED light is delivered through a long optical fiber path.

[0137] In one embodiment, LEDs 1102 and 1202 may be used to process, cure a formulation, or indicate device status (ie, operating mode or charging status).

[0138] The LED can be any type of single wavelength (laser LED) or a range of wavelengths. In one embodiment, the LEDs 1102, 1202 are capable of producing light over a wide range of the electromagnetic spectrum. In one embodiment, light therapy has been used on the scalp to treat skin conditions. In one embodiment, light therapy has been used to stimulate cells of hair follicles.

[0140] In one embodiment, the wavelength output of LEDs 1102, 1202 includes one or more gallium indium nitride (GaInN) LEDs having a wavelength output of about 360nm-370nm. In other embodiments, LEDs 1102, 1202 emit electromagnetic energy in a wavelength range from about 200nm to about 2000nm, which includes wavelengths in the ultraviolet range (about 350nm) and near infrared (about 1200nm).

[0141] refer to Fig.15 , one embodiment of an apparatus 100b is schematically shown to illustrate the main components, wherein like numerals represent like components described herein.

[0142] In one embodiment, the device 100b includes a power source 118. The device 100b can be powered by alternating current (AC) or direct current (DC). In one embodiment, the device 100b is powered by common household AC power, which relies on an electrical wire (not shown) to power the device 100b. In one embodiment, the device 100b is powered by DC power, such as a rechargeable battery that can be charged by plugging into a household AC outlet. A DC powered device 100b allows the device to be used without having to keep or be near an electrical outlet.

[0143] In one embodiment, the device 100b includes a formulation dispenser 112 as described above.

[0144] In one embodiment, the cartridge 102 has a product identification label 154 ( Figure 1 ), which product identification tag can convey operating instructions for the device 100b based on the specific formulation contained in the cartridge 102. The device 100b may include a product identification tag reader 156 ( Figure 1) which is capable of reading the product identification tag 154 and processing the coded signal into instructions for operation and control of the device based on the specific formulation. In addition to the above description, the product identification tag can also include dispenser mode formation, such as flat fan and cone, wide and narrow, solid and hollow, stream and mist.

[0145] In one embodiment, the hair formulation includes a cationic, anionic or zwitterionic polymer and a surfactant may be used to provide a charge to the formulation that may interact with the hair or scalp. In one embodiment, the hair formulation may be charged with other materials, such as chelating agents, which may also function as complex molecules that hinder the charged interactions between the charged materials and their interaction with the hair fiber to allow more effective charged interactions to occur.

[0146] Given that hair retains an electrical charge (typically negative at neutral pH), this charge can be affected by the presence of charged materials (such as those described above) in the formulation as they are applied to the hair, thereby allowing for better and more efficient attraction / deposition or repulsion and aiding removal.

[0147] Dispenser 112 can distribute one or more preparations in the form of mist or liquid or any form between the two through the pointed tip 108 and the tip 602, 1702, 802, 1100, 1200. In one embodiment, dispenser 112 includes a compressor, a pump or an ultrasonic generator to produce mist from the preparation. In the case of a pump or compressor dispenser 112, this dispenser 112 makes air or preparation flow at high speed, thereby pushing the preparation through the fine nozzle designed for atomization at the opening 130. In the case of a pump or compressor dispenser, a single dispenser 112 can be placed in device 100b. Then, the outlet of the compressor or pump dispenser 112 is guided to each pointed tip 108 through a system of conduits and leaves from the nozzle at the opening 130.

[0148] In one embodiment, the dispenser 112 is an ultrasonic jet that generates mist or vapor to distribute the formulation. This has the advantage of gentle dispersion of the formulation to reduce the amount of waste and improve the control of coverage. In one embodiment, the jet uses an ultrasonic generator that contacts the formulation, where the frequency of the ultrasonic waves is sufficient to generate mist. Ultrasonic jets also include "grid" jets that have a vibrating grid that just contacts the surface of the formulation to generate mist. Any form of ultrasonic atomizer can use a piezoelectric element.

[0149] In one embodiment, dispenser 112 is operated by depressing switch 106 ( Figure 1 and Figure 2). In one embodiment, the switch 106 is placed on the front side of the upper portion of the handle 104 to allow operation with the index finger. In one embodiment, the switch 106 is a momentary switch whose default position is the off position. The momentary switch only needs to be activated once, regardless of the length of activation, to dispense a measured amount of the preparation. Keeping the momentary switch 106 depressed for a longer time will not dispense more preparation than the pre-measured amount. In another embodiment, the switch 106 is a switch that starts and stops the dispenser 112 based on opening and closing the switch.

[0150] In one embodiment, the device 100b includes an electrostatic charger 152. The electrostatic charger can generate a positive or negative charge at a target area of ​​the scalp or hair or both. The electrostatic charger 152 is connected via an electrical conductor to the electrode 150 on the end of one or more of the prongs 108, or to one of the conductive posts in the case of the tips 602, 1702, 802, 1100, and 1200. Suitable conductive materials for the tips 602, 1702, 802, 1100, and 1200 may include, for example, copper, nickel, stainless steel, aluminum, or any alloy thereof.

[0151] In one embodiment, the device 100b includes a microcurrent generator 1158. The microcurrent generator 1158 provides a voltage between the positive and negative terminals (GND) to apply a small amount of electrical current (microcurrent) within a given frequency range to an area of ​​skin or hair. In one embodiment, the amount and frequency of electrical stimulation can be within the range of electrical processes that occur naturally in tissues and cells. For example, microcurrent therapy has been used to stimulate hair growth, heal injured tissue, and regenerate skin through the stimulation of collagen and increased blood flow. In one embodiment, the generation of microcurrent is provided by a waveform generator. The controller 148 sends a modulated wave signal that sets the amplitude, frequency, and polarity of the desired microcurrent.

[0152] In one embodiment, the tips 602, 1702, 802, 1100, and 1200 are connected to a microcurrent generator 1158. The tips 602, 1702, 802, 1100, and 1200 made of conductive material allow one of the cylinders of the tips to be used as a positive terminal, which can be used to provide microcurrent to the scalp, where the scalp serves as a ground (GND) path, which also includes the skin and tissue between the scalp and the negative terminal (e.g., on the handle 104 of the device 100b) placed in contact with the hand. In one embodiment, microcurrent can be applied between multiple tips, with one tip serving as a positive terminal and another tip serving as a GND terminal.

[0153] In one embodiment, the tips 602, 1702, 802, 1100, and 1200 made of conductive material also allow the tips to be used as sensors. In one embodiment, one of the cylinders of each of the tips 602, 1702, 802, 1100, and 1200 can be used as a positive terminal, while a second cylinder of the same or different tip is used as a negative terminal. In one embodiment, the impedance between any positive terminal and any negative terminal can be measured to determine the scalp moisture level at a specific point or a more general area.

[0154] In one embodiment, impedance may be measured from different tips to determine scalp moisture levels over a wider area.

[0155] In one embodiment, the impedance between the positive or negative terminal and the scalp (via a conductive return path to the handle) can be measured to determine if the tip is in contact with the scalp (skin). This is useful if the application requires scalp contact; for example, in a preparation treatment and vacuum system, the scalp is being treated and there is a risk of the vacuum pulling hair if the device is not operating directly on the scalp.

[0156] In one embodiment, the tips 602, 1702, 802, 1100, and 1200 are connected to an electrostatic charger 152. In one embodiment, the electrostatic charger 152 is used to generate a positive or negative charge on the scalp or hair or both to attract or repel the agent to the charged area. The tips 602, 1702, 802, 1100, and 1200 are conductive to allow the tips to act as electrodes. In one example, the positively charged area is created by repelling electrons from the area, and in another example, the negatively charged area is created by attracting electrons to the area. Electrostatic charging can be performed by contact electrical charging, inductive electrical charging, etc.

[0157] In another example, the formulation is charged as it passes through the tips 602, 1702, 802, 1100, and 1200. Negatively charged hair formulation droplets are attracted to a target that may be at a lower electrical potential.

[0158] In one embodiment, the device 100b includes a vacuum system 114 having a vacuum generating motor and a collector 116. In one embodiment, the motor can be a variable speed motor. The vacuum motor 114 is connected to an impeller blade that allows air flow to enter through the vacuum inlet opening 132 at the tip 108, or in the case of the tips 602, 1702, 802, 1100 and 1200, one of the cylinders can be used for vacuum. The motor guides the air flow to enter through the opening 132 at the tip 108 or one of the cylinders of the tips 602, 1702, 802, 1100 and 1200. The air flow can carry the used preparation and any debris and oils rinsed out of the hair by the preparation, which are then captured by the collector 116 and the air is exhausted from the device 100b. In one embodiment, the collector 116 includes an annular vent placed at the rear of the device 100b. The vent allows the air flow to leave the device 100b, while the used and debris are captured in the collector 116.

[0159] In one embodiment, the vacuum motor 114 is operated by a multi-position, multi-function selector switch 110 ( Figure 4 ). For example, the selector switch 110 can be a slide switch or a dial switch having two or more positions, or a push button switch having two or more positions. In one embodiment, the vacuum selector switch 110 includes a setting for shutoff and one or more vacuum speed settings, such as high and low. In one embodiment, the vacuum switch 110 is placed on the rear side of the lower portion of the handle 104, for example, to allow operation with a thumb. The vacuum switch 110 can be isolated for uninterrupted vacuum. A light emitting diode 118 can be used to illuminate the selected position. The selector switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch can replace the selector switch, wherein the default position of the momentary switch is the off position and the momentary switch must be pressed to start the vacuum motor. In one embodiment, the device 100b includes both a vacuum selector switch and a momentary switch, wherein the momentary switch is used to operate the vacuum motor when pressed and at the speed setting on the selector switch.

[0160] In one embodiment, the device 100b includes a controller 148. In one embodiment, the controller 148 is a digital device. The controller 148 may include one or more hardware circuits connected to a printed circuit board, or all circuits may exist on a single chip. The controller 148 may include at least a microprocessor core and memory. The hardware may be designed for a small manual device. The microprocessor may be implemented as multiple processors that work in parallel and serially to execute instructions according to pre-programmed logic.

[0161] Instructions for controlling the dispenser 112, the electrostatic charger 152, the microcurrent generator 1158, and the vacuum 114 may be stored in a controller memory. A memory is any type of computer-readable medium or computer storage device that can be accessed and used by one or more microprocessors to execute instructions. Instructions may be stored in a high-speed memory such as an EEPROM, flash memory, RAM, or other programmable non-volatile memory.

[0162] In one embodiment, the controller 148 communicates with the dispenser 112, the electrostatic charger 152, the microcurrent generator 1158, and the vacuum 114. The controller 148 can also read the information provided on the cartridge 102 to give instructions specific to the preparation to the dispenser 112 and the electrostatic charger 152. The controller 148 can configure one or more of the tips 602, 1702, 802, 1100, and 1200 to be electrically connected to the microcurrent generator 1158 and the electrostatic charger 152. The controller 148 can configure one or more of the tips 602, 1702, 802, 1100, and 1200 to be connected to the dispenser 112 to deliver the preparation in the desired form and amount. The controller can control the LEDs 1102 and 1202 to operate at a specified power and wavelength.

[0163] In one embodiment, the controller 148 may connect one or more tips to serve as the positive and negative terminals of the microcurrent generator 1158 .

[0164] In one embodiment, the controller 148 may connect one or more tips to serve as electrodes for the electrostatic charger 152 .

[0165] In one embodiment, the controller 148 may connect one or more tips to the positive terminal of the microcurrent generator 1158, and the scalp (skin) is part of the ground path to the negative terminal located on the device 100b.

[0166] In one embodiment, the controller 148 may calculate the impedance between the positive and negative terminals of any one or more of the tips.

[0167] In one embodiment, the controller 148 uses impedance to determine whether the tips are in contact with the scalp. In one embodiment, the controller 148 may turn off the vacuum 114 or not allow the vacuum to turn on when it is determined that one or more tips are not in contact with the scalp.

[0168] In one embodiment, the controller 148 may use the measurement of impedance to determine the wetness of one or more areas on the scalp.

[0169] In one embodiment, the controller 148 can turn on the LEDs 1102 and 1202 based on predetermined instructions. For example, some preparations may require the application of light of a specific wavelength. The controller 148 can be used to control the LEDs 1102 and 1202 to provide a light therapy treatment. The controller 148 has instructions for determining the wavelength and power to be applied to the light therapy.

[0170] In one embodiment, the controller 148 can control the amount of formulation dispensed by the dispenser 112. For example, the controller 148 can turn on a pump or compressor for a predetermined amount of time associated with a specific amount of formulation. In one embodiment, the dispenser 112 uses a positive displacement pump, and therefore, an encoder can be used to measure the volume displaced per rotation of the pump. When the rotation of the pump equals the volume of formulation to be dispensed, the controller 148 can turn off the pump.

[0171] The use of the device 100b is instinctive, and the overall shape of the device 100b is familiar to users from other hair applications (such as hair dryers), resulting in simple and intuitive use of the device 100b. The device 100b can improve the current use of aerosol dry shampoos. The device 100b dispenses a controlled amount of formulation so that the formulation slides onto and into the hair when the user combs or brushes the hair. The device 100b is in contrast to an aerosol sprayer, which may spray more than necessary and produce a large cloud of mist that covers the outer area of ​​the user's head.

[0172] Fig.16 and Fig.17 is a schematic diagram of an embodiment of a device 100d, which can be equipped with a plurality of different tips. The device 100d can be used to clean hair that can be used with a dry shampoo formulation, which has additional functions by activating the tips for dispensing, sensing, massaging and other uses separately. In one embodiment, the device 100d uses a brush-like or comb-like structure, which relies on a combination of mechanical and chemical actions to deposit the required formulation for cleaning, remove formulations with unwanted particles, and further provide additional beauty or health attributes. The intuitive action provides a familiar gesture that is easily integrated into the current beauty and hair care program. In addition, the device 100d can include various types of hollow conductive or non-conductive tips (602, 1702, 1100 or 1200) arranged in a brush or comb configuration. A brush configuration is shown in the figure, however, the device 100d can be configured to have a tip of a comb configuration, that is, a single row. However, the tip arranged in a brush configuration allows various advantages, such as the individual actuation of the tip for applying one or more treatments, dispensing or massaging using only some but not all of the tips.

[0173] In one embodiment, device 100d includes massage tips that are individually controlled in XYZ motion by actuators. Tips individually dispense precisely measured volumes of scalp product only when in contact with the scalp (through the use of open / short or dielectric skin contact sensors). Individually activated tips spray hair product (dry shampoo or hair dye) in a tightly controlled pattern (i.e., flat fan pattern). Personalized scalp and hair products are stored in replaceable cartridges. The addition of a camera can determine hair density, tone, and dryness related to scalp and hair conditions. The addition of an LED can further process the hair, facilitate camera imaging, and be used for formulation curing.

[0174] In one embodiment, the device 100d releases the hair and / or scalp product as a vapor cloud (mist) via ultrasonic waves (similar to a home humidifier). The gentler dispersion of the product reduces the amount of waste and improves control of coverage. This solution is in contrast to aerosol sprayers, which can spray more than needed and create a large cloud of mist that covers the outer area of ​​the user's head.

[0175] In one embodiment, a multi-use device 1100 is depicted having individually controlled tips for dispensing formulation and other uses.

[0176] In one embodiment, each tip is constructed as a junction of a first half cylinder as a positive conductor and a second half cylinder as a negative conductor, separated by a non-conductive gasket. In terms of geometry alone, each tip is a cylindrical chamber longitudinally divided into two or more isolated chambers, or two or more isolated cylinders longitudinally fixed to each other.

[0177] In one embodiment, the tip used as the positive terminal can be used to provide additional functionality to the tip. In one embodiment, a microcurrent can be provided to the scalp, where the scalp serves as a GND path, the GND path also including the skin and tissue between the scalp and the negative terminal, which is placed in contact with the hand, such as on the handle 104 of the device 100d. The tip can provide a microcurrent to the scalp, where the scalp serves as a conductive path between any positive terminal and any negative terminal. Alternatively, a microcurrent can be applied between multiple tips, where one tip serves as a positive source and another tip serves as a GND.

[0178] In one embodiment, the impedance between the positive and negative terminals can be measured to determine the scalp moisture level. Alternatively, the impedance between multiple tips can be measured to determine the scalp moisture level over a wider area. The impedance between the positive or negative terminal and the scalp (via the return path to the handle) can be measured to determine whether the tip is in contact with the scalp (skin). This is useful if the application requires scalp contact; for example, in a formulation treatment with a vacuum system, the scalp is the treatment target and the vacuum risks pulling the hair if it does not operate directly on the scalp.

[0179] The LED can be placed at the end of the tip and powered by both terminals. If the LED is powerful, the heat dissipation can be absorbed by the conductive material (heat sink). The LED at the end of the tip will deliver more energy to the scalp than an LED at the base and / or delivered through a long fiber optic path. The LED can be used to treat, cure the formulation, or indicate the device status (i.e., operating mode or charging status).

[0180] A series of laser cut holes (perforations) along the length of the tip can be used to deliver the formulation to the scalp and / or hair. Alternatively, if only the scalp is targeted, a single opening at the end of the tip can be used.

[0181] The functionality of the tip and its separate conductive halves can be dynamically controlled and reallocated by a central integrated circuit within the body of the brush device. Even if the tip is not made of a conductive material, the "two or more cylinders" structure may be useful if the application involves mixing a formulation or dispensing a formulation with vacuum to a small, controlled target area on the scalp.

[0182] In one embodiment, the tip is conductive allowing for a variety of options, for example, the conductive tip can be used with a microcurrent generator, or the conductive tip can be used as a sensing instrument to detect skin contact, or the conductive tip can be used to power a light emitting diode (LED) for light therapy, or the conductive tip can be used to provide vibrations in one to three axes.

[0183] In one embodiment, the device 100d is provided with a tip that utilizes a hollow structure that allows for more precise delivery of the formulation. For example, the formulation can be dispensed only from these tips to form a specific spray pattern. In one embodiment, the conductive tip is made of more than one cavity extending the length of the tip, which allows one or more formulations to be dispensed through the tip. In one embodiment, the tip is non-conductive, but still includes a cavity extending the length of the tip to provide a dispensing feature.

[0184] In one embodiment, the device 100d is shaped into a well-known, familiar style of hair application to inspire trust and confidence in the device, thereby enabling intuitive use and gesture when using the device.

[0185] refer to Fig.16 and Fig.17 In one embodiment, the device 100d includes a handle 104 connected to a generally cylindrical portion 138. The handle 104 is connected to the device 100d at an obtuse angle relative to the front end of the device 100d. The handle 104 helps balance the weight of the device for more comfortable use and easier control. Control buttons may also be located on the handle.

[0186] refer to Fig.17, on the back side, the device 100d can include a cylindrical housing 136 of smaller diameter, which accepts a removable cartridge 102 containing a hair or scalp treatment formulation. The device 100d allows the cartridge 102 to be easily exchanged to provide different formulations. The cartridge 102 can be configured as a refillable cartridge or a disposable cartridge. In one embodiment, the device 100d can be configured to hold more than one cartridge 102, wherein each cartridge can be filled with different formulations for different treatments. Alternatively, some applications may use two or more different formulations, which requires the application of two formulations to achieve the desired treatment.

[0187] From the rear housing 136 forward, the outer shape of the device 100d gradually increases to a larger outer diameter portion 138 than the diameter of the cartridge housing 136. In one embodiment, the device 100d includes a body structure having a generally cylindrical or minimally tapered portion 138 from the rear end to about the middle of the length of the device. In one embodiment, the handle 104 is connected to the rear side of the portion 138.

[0188] In one embodiment, the device 100d has tips 602, 1702, 1100, 1200 arranged in a brush configuration (e.g., concentric circles). The device 100d includes a brush head 140 connected to a central portion 138. The brush head 140 is the portion of the device 100d that holds the tips 602, 1702, 1100, or 1200. In one embodiment, the brush head 140 is stationary relative to the device and is not actuated because the individual tips are individually actuated to vibrate, and therefore, there is no need to have a rotating or vibrating brush head. In addition, the tips are also configured to be able to control the dispensing of formulations from some individual tips rather than other tips. This allows some tips to be "turned on" and other tips to be "turned off" to create different spray patterns from the brush head.

[0189] In one embodiment, the brush heads 602, 1702, 1100, 1200 are arranged on the brush head 140 in concentric circles. In one embodiment, the tips 602, 1702, 1100, 1200 are configured to be able to dispense two different preparations. In one embodiment, the tips 602, 1702, 1100, 1200 have a cavity extending the entire length of the tip. The tips 602, 1702, 1100, 1200 are at least one diameter in length. However, the tips 602, 1702, 1100, 1200 can be configured as several diameters in length, so the ratio of width to length can be from 1 to 1 to 1 to 20 or more. The tips 602, 1702, 1100, 1200 can be flexible or non-flexible. The tips 602, 1702, 1100, 1200 can also be connected to the brush head 140 in a flexible manner. Separated chambers allow one or more preparations to be delivered through each chamber without mixing. Preparations can be separated in the corresponding chamber until the preparation leaves the chamber. The distribution of preparations can be realized by configuring each chamber to have an opening along the length of the chamber or only at the end of the chamber or along the width and end of the chamber. In addition, each chamber in the tip can have a valve or other device to control the distribution from only one chamber or two chambers. Controlling the distribution of preparations only from certain tips on the brush head enables distribution in multiple modes, such as conical spray, fan spray, etc.

[0190] refer to Fig.18 , one embodiment of an apparatus 100d is schematically represented to illustrate the main systems.

[0191] In one embodiment, the device 100d includes a power source 128. The device 100d can be powered by alternating current (AC) or direct current (DC). In one embodiment, the device 100d is powered by common household AC power, which relies on an electrical cord (not shown) to power the device 100d. In one embodiment, the device 100d is powered by DC power, such as a rechargeable battery that can be charged by plugging into a household AC outlet. A DC powered device 100d allows the device to be used without having to keep or be near an electrical outlet. The power source 128 is configured to provide power to any system that requires power, such as the controller 148, the dispenser 112, the massage module 1152, the vacuum motor 114, the camera 2158, the LEDs 1102, 1202, and the tips 602, 1702, 1100, and 1200.

[0192] In one embodiment, the device 100d includes a formulation dispenser 112. In one embodiment, the formulation is stored in a replaceable or refillable cartridge 102. The cartridge 102 can be removed from the device 100d to be refilled or disposed of and replaced with a new, complete cartridge. Once emptied, the cartridge 102 can be replaced with a new cartridge filled with the same or different formulation, or the cartridge can be refilled with the same or different formulation. Figure 1 As shown, cartridge 102 is inserted through the back of device 100d. Cartridge 102 is connected to supply scalp or hair preparation to dispenser 112. In one embodiment, device 100d can hold multiple cartridges, wherein each cartridge is filled with a different preparation, which can be dispensed to achieve different treatments and for different areas of the scalp and hair.

[0193] In one embodiment, the cartridge 102 has a product identification label 154 ( Figure 1 ), which can communicate operating instructions for the device 100d based on the specific formulation contained in the cartridge 102. The device 100d may include a product identification tag reader 156 ( Figure 1 ) which is capable of reading the product identification tag 154 and processing the encoded signal into instructions for operation and control of the device based on the specific formulation. Product identification tags include, for example, bar codes, 2-D bar codes, RFID, etc. The product identification tag is encoded with a machine-readable signal that conveys the device settings for a specific formulation. Different formulations may have different device settings. For example, the product identification tag may include a dispenser setting from liquid to fine droplets, medium droplets, or coarse droplets. The product identification tag may also include dispenser pattern formation, such as flat fan vs. cone, wide vs. narrow, solid vs. hollow, stream vs. mist. The product identification tag may also include instructions for operating LEDs 1102, 1202. Different formulations may also be used to treat different areas of the scalp and hair. Different formulations may also be used to provide different treatments for the scalp and hair.

[0194] Distributor 112 can distribute one or more preparations in a fine mist or liquid or any form therebetween by means of tip 602, 1702, 1100, 1200. In one embodiment, distributor 112 includes a compressor, a pump or an ultrasonic generator to produce mist from the preparation. In the case of a pump or compressor distributor 112, such distributor 112 makes air or preparation flow at high speed, thereby pushing the preparation through a fine opening. In the case of a pump or compressor distributor, a single distributor 112 can be placed in device 100d. Then, the outlet of the compressor or pump distributor 112 is guided to each individual tip by a conduit system.

[0195] In one embodiment, the dispenser 112 is an ultrasonic jet that generates mist or steam to dispense the formulation through a separate tip. This has the advantage of gentle dispersion of the formulation to reduce the amount of waste and improve the control of coverage. In one embodiment, the jet uses an ultrasonic generator in contact with the formulation, where the frequency of the ultrasonic wave is sufficient to generate mist. Ultrasonic jets also include "grid" jets that have a vibrating grid that just contacts the surface of the formulation to generate mist. Any form of ultrasonic atomizer can use a piezoelectric element.

[0196] In one embodiment, both the ultrasonic generator and the vibrating mesh injector can use piezoelectric materials to generate vibrations at ultrasonic frequencies. In one embodiment, the same piezoelectric material used in the injector can also be used to drive the tactile system. The tactile system can include a massage treatment system, but can also include any system that provides a sensor experience, such as heating and related ultrasonic treatment. Atomizers may rely on generating frequencies in excess of 1 MHz. Injectors capable of generating frequencies in excess of 1 MHz can also be used to drive the tactile system to generate heat, which can be used to treat the skin and scalp alone or in conjunction with the distribution of the preparation. Some injectors may also rely on ultrasonic frequencies less than 1 MHz. In one embodiment, the injector can be used to drive the tactile system to generate frequencies within a range that is designed to deliver treatment compounds to the skin and scalp in conjunction with the distribution of the preparation. Therefore, there is an advantage when the same piezoelectric material used in the injector system is used in the tactile system.

[0197] In one embodiment, each tip can include a valve at the entrance of one or two chambers. The valve has an actuator that opens and closes the valve. Each valve of each tip can be actuated to open or close independently of other valves of other tips. By opening or closing the valve at each individual tip, the preparation can be controlled to flow out only from the selected tip in a controlled mode (e.g., cone, flat fan, stream, multiple streams, pulses, etc.). In addition, the valve with control distributed from the two chambers of the tip allows the control preparation to flow out from one or two chambers.

[0198] Fig.19Schematic diagram of the end of the tip 602, 1702, 1100, 1200. In one embodiment, the tip is arranged in a circular pattern of increasing diameters of a small diameter 908, a medium diameter 910, and a large diameter 912. In one embodiment, only the valve of the tip connected by one of the circles 908, 910, or 912 can be opened, so that the preparation is dispensed in the small cone 908, the medium cone 910, and the large cone 912 to cover the small area, the medium area, and the large area of ​​the scalp or hair. The controller is instructed to open the tip located in the pattern to dispense the preparation according to the pattern and close the tip not located in the pattern. The actuation of the valve of the individual tip is not limited to the circular pattern. In one embodiment, the valve of the tip can be actuated in a linear pattern. Line 914 only connects the tips that will be opened to dispense the preparation in a fan-shaped pattern, and the remaining tips that are not in a linear pattern will remain closed. Any combination of individual tips can be selected to dispense the preparation only from certain tips rather than from other tips to achieve different patterns.

[0199] In one embodiment, dispenser 112 is operated by depressing switch 106 ( Figure 1 and Figure 2 ). In one embodiment, the switch 106 is placed on the front side of the upper portion of the handle 104 to allow operation with the index finger. In one embodiment, the switch 106 is a momentary switch whose default position is the open position. The momentary switch only needs to be activated once, regardless of the length of activation, to dispense a measured amount of the preparation. Holding the momentary switch 106 depressed for a longer time does not dispense more preparation than the pre-measured amount. In another embodiment, the switch 106 is a switch that starts and stops the dispenser 112 based on opening and closing the switch.

[0200] In one embodiment, the valves on the tips 602, 1702, 1100, and 1200 are only actuated if the individual tip selected for dispensing is in contact with the skin. In one embodiment, the tips 602, 1702, 1100, and 1200 made of conductive material allow the tips to be used as contact sensors.
