Disclosure of Invention

In one embodiment, the hair treatment system intelligently treats or judges hair and scalp per area. In one embodiment, a proximity sensor, such as a camera or Infrared (IR), or both a camera and an IR sensor are combined with a contact sensor for approximating distance and position and generating commands that modify the dispensing or judging product along the length of the hair and into the scalp.

In one embodiment, the hair treatment system facilitates pattern application and treatment dosage (e.g., root and end of hair) as well as distinguishing scalp from hair and air.

In one embodiment, the hair treatment system controls the outflow or direction of scalp and hair treatments to minimize wasted and breathable mist.

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

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

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

In one embodiment, a cartridge containing a dry shampoo solution is embedded in the applicator device. When activated via the on button, the dry shampoo solution is dispensed via a pump into a series of small-hole tips or teeth therein in an amount. When a user brushes or brushes hair, the solution slides onto the hair and into the hair.

In one embodiment, the device releases hair and scalp products as a vapor cloud (mist) by ultrasonic waves. This has the advantage of gentle dispersion of the product to reduce the amount of waste and improve control of coverage. The solution may be sprayed more than necessary and create a large cloud of mist covering the outside area of the user's head, as opposed to an aerosol sprayer.

In one embodiment, the multi-purpose device cooperates with a new brush or comb tip for dispensing.

In one embodiment, each tip is configured as a junction of a half-cylinder positive conductor and a half-cylinder negative conductor separated by a non-conductive washer (insulator).

In one embodiment, each brush (or comb) tip is a cylinder chamber that is a cylinder that is longitudinally split into two or more chambers that are electrically isolated from each other or two or more coaxial cylinders that are electrically isolated from each other.

In one embodiment, the tip has a positive terminal that can be used to provide micro-current to the scalp, where the scalp acts as a Ground (GND) path.

In one embodiment, brush (or comb) tips may provide micro-current to the scalp, where the scalp acts as a conduction path between the positive and negative terminals of the different tips.

In one embodiment, a micro-current may be applied between a plurality of tips, one of which serves as a positive source terminal and the other as a GND terminal.

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

In one embodiment, the impedance between the plurality of tips may be measured to determine the scalp moisture level over a wider area.

In one embodiment, the impedance between the positive or negative terminal and the scalp (via the return path to the handle) may 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 formulation treatment and vacuuming system, the scalp is the treatment target and if not directly operated on the scalp, vacuum runs the risk of drawing hair.

In one embodiment, a Light Emitting Diode (LED) may be placed at the end of the tip and powered by two terminals.

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

In one embodiment, the LED is placed at the distal end of the tip. In this configuration, the LEDs may deliver more energy to the scalp than would be delivered at the base of the tip or through a long fiber optic path.

In one embodiment, the LED may be used to process, cure a formulation, or indicate a device state (i.e., an operational mode or state of charge).

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

In one embodiment, if only the scalp is targeted, a separate opening at only the end of the tip may be used.

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.

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

In one embodiment, the portable-sized brush or comb device includes a massaging tip that is individually controlled in XYZ motion by an actuator. The tip alone dispenses a precisely measured volume of scalp product only when in contact with the scalp (by using an open/short or dielectric skin contact sensor). The individually activated tips spray the hair product (dry shampoo or hair dye) in a tightly controlled fashion (i.e., in a flat fan-like fashion). The personalized scalp and hair products are stored in a replaceable cartridge. The addition of the camera can determine the hair density, tone and dryness associated with scalp and hair conditions. The addition of LEDs can further treat the hair, facilitate camera imaging, and be used for formulation curing.

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

Detailed Description

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, 2017/036020, 2019/0098977, 2019/0209077. In accordance with the present disclosure, devices for treating hair or scalp or both hair and scalp may be improved by including a sensor that detects the precise position or proximity of the device relative to the scalp and hair. Devices with such sensors can use this information to control the process being conveyed.

In accordance with the present disclosure, providing a sensor allows more "smart" devices to be programmed to perform an adjustment process based on the position or proximity of the hair treatment device to the scalp or hair or whether the device is in actual 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 shampoos, bleaches, colorants, and other formulations.

In one embodiment, a hair and scalp treatment system according to the present disclosure is embodied in a hand-held, electrically powered device. The device shown in the figures is an example of a hair or scalp treatment system. However, previously known hair and scalp treatment devices may also be modified to have the intelligent functions described herein. For example, the device 100a in fig. 1 shows a relatively large tip that can be used to dispense a formulation, act as a vacuum or blower, and provide light and electrostatic treatment. However, in other embodiments, the tines may be replaced with a brush head having bristles or a comb having teeth.

Individuals wash their hair with traditional wet water-based shampoos with ever-decreasing frequency. Some reasons may be provided for this type of shampoo reduction, such as preventing hair loss and hair damage or saving time and effort. Dry shampoos are increasing. Attempts to extend the time between salons to save costs have led to an increasing interest in colored dry shampoos for root touch-up. The dry shampoo is mainly packaged in a spray bottle. However, spray bottles create problems with respect to inhaling the product and inadvertently spraying the face (particularly the eyes). The spray bottle is inaccurate in both spray direction and spray amount. Furthermore, spray bottles are unsuitable when traveling or using a public bath. Dry shampoos do not clean the scalp and can actually damage the scalp. Nevertheless, it is believed that: healthy hair is obtained by caring scalp. The "dry" method of cleaning the scalp involves brushing or combing to apply grease to the hair. Scalp care and scalp instruction formulations may be applied by pipette, foam or powder and require manual separation of your hair. The powder and foam are on the hands. Dropping excess product onto the scalp can result in hair loss and greasy looking hair. Reusable and closed loop product designs are an ever-increasing demand.

The present disclosure relates to a device for cleaning hair, which may be used, for example, with dry cleaning hair water or other formulations. Scalp and hair preparations are useful for treating dandruff, hair loss, reduced pressure, itching, color and tone, oiliness, appearance, hair curling, volume, luster, dryness, density, and the like. However, a more intelligent method is needed to apply the formulation to the scalp and hair.

In one embodiment, the device uses a brush or comb structure that relies on a combination of mechanical and chemical action to deposit the desired formulation for cleaning, remove the formulation with unwanted particles, and further provide additional cosmetic or health attributes. Comb action provides a familiar pose that is easy to incorporate into current cosmetic and hair care procedures. Furthermore, the device may comprise hollow conductive tips arranged in a brush or comb configuration. The conductive tip allows several options, for example, the conductive tip may be used with a microcurrent generator, or the conductive tip may be used with an electrostatic charger to charge the scalp or hair with positive or negative charges that will attract hair formulation to the charged area.

In one embodiment, the device is provided with a pointed tip or tip that utilizes a hollow structure that allows for more accurate delivery of the formulation. In one embodiment, the prongs and tips may be used to provide micro-current or electrostatic charge to the scalp and hair. In one embodiment, the tip may be used as a contact sensor. In one embodiment, the tip may be used to measure impedance to determine moisture content.

In one embodiment, the device is shaped in a well-known familiar hair application pattern to motivate trust and confidence in the device, resulting in intuitive use and posture when the device is used.

Referring to fig. 1-5, 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. The control buttons may also be located on the handle.

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

From the rear housing 136 forward, the outer shape of the device 100a gradually increases to a larger outer diameter portion 138 as compared to the housing 136 diameter. In one embodiment, the device 100a includes a body structure having a generally cylindrical or minimally tapered taper portion 138 from the trailing end to about the middle of the device length. In one embodiment, handle 104 is connected to the rear side of portion 138. Then, from the proximal side of the cylindrical or smallest conical portion 138, the device 100a presents a more pronounced conical or decreasing elliptical shape 140 in a top-to-bottom plane (i.e., viewed from the left or right) from about the middle of the device 100a to about one third or one quarter of the device's length. However, in the side-to-side plane (i.e., as 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. The tip 108 may be replaced with a tip arranged in a brush or comb configuration, as described herein.

Distal to the smaller end of the cone or oval 140, then, the device 100a has a transition portion 142 that forms one or more dispensing tines 108 at the front end such that each tine 108 is separated from the other tines. Although the prongs 108 are shown as being connected to a hair or scalp treatment system, the device 100a may be configured as a brush or comb.

Referring to fig. 2 and 5, each prong 108 has a tapered conical shape from an initial connection at the cross-section of the transition portion 142 to the end of the prong 108 in the side-to-side plane and top-to-bottom plane.

In fig. 5, the tip 108 is shown as having a rounded tip when viewed from a bottom (or top) plane. However, in fig. 3, 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 circle (truncated rounded shape). The rounded tips of the prongs 108 may separate the hair for better access to the scalp and roots. Rounded tip 108 includes "churning" and chamfering for cleaning and massaging actions.

In fig. 5, the chamfered portion of the tip 108 has an opening 130 for dispensing one or more formulations. In one embodiment, the openings 130 may be static, meaning that the spray or dispense direction is set and cannot be adjusted. In one embodiment, the openings 130 may be directional, meaning that the spray or dispense direction may be controlled. For example, the opening 130 may be provided on a rotating ball controlled by a micro-actuator. In one embodiment, a plurality of openings may be provided, wherein each opening is oriented in a different direction and the formulation is dispensed from the selected opening in a preferred direction.

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 circular pattern. In one embodiment, the dispenser 112 may control the form in which the formulation is dispensed. For example, the formulation may be sprayed in different shaped patterns, such as flat fan and cone, wide and narrow sprays, solid and hollow sprays, and streams and mists. In one embodiment, the formulation is dispensed through an adjustable conical nozzle that moves forward and backward around a central rod to adjust the spray pattern.

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

In the illustrated embodiment, each prong 108 is shown having an opening 130 for dispensing and an opening 132 for drawing a vacuum. However, in one embodiment, there may be a dedicated tip with only openings for dispensing the formulation and a dedicated tip with only openings for vacuum. In one embodiment, there may be multiple openings on each tip 108 to provide for dispensing different formulations from the same tip. This may be advantageous when the two formulations act together to achieve the 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.

In one embodiment, the apparatus 100a includes an electrostatic processing 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 tip 108. The electrode 150 may also electrostatically charge the hair formulation droplets as they are dispensed from the opening 130. The charged hair formulation will then be attracted or repelled to the scalp or targeted area of hair depending on the particular charge created. The electrode 150 is electrically connected to an electrostatic charger. In one embodiment, the electrode 150 may be surrounded by an electrically insulating material. In one embodiment, the device 100a may have multiple hair and scalp treatment systems. The device 100a is also provided with one or more sensors, including contact sensors, proximity sensors, accelerometers, and the like. The sensors provide inputs 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.

Referring to fig. 6, a device 100a is schematically represented to illustrate the use of sensors in a hair and scalp treatment system. The device 100a may have one or more processing 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 processing system 146, and a tactile vibratory massager 158. In one embodiment, the apparatus 100a may comprise the processing system described above, only one processing system, or a combination of more than one processing system.

In one embodiment, the device 100a may be powered by Alternating Current (AC) or Direct Current (DC). In one embodiment, the device 100a is powered by a common household alternating current that powers the device 100a by means of an electrical cord (not shown). In one embodiment, the device 100a is powered by direct current, such as a rechargeable battery that may be charged by plugging into a household alternating current outlet. The dc power supply device 100a allows the device to be used without being retained or in the vicinity of an electrical outlet.

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. Cartridge 102 may be removed from device 100a to be refilled or used for disposal and replacement with a new complete cartridge. Once emptied, the cartridge 102 may be replaced with a new cartridge filled with the same or a different formulation, or the cartridge may be refilled with the same or a different formulation. As shown in fig. 1, the cartridge 102 is inserted through the back side of the device 100 a. The cartridge 102 is connected to supply scalp or hair preparation to the dispenser 112. In one embodiment, the device 100a may contain multiple cartridges, wherein each cartridge is filled with a different formulation that may be dispensed to achieve different treatments and for different areas of the scalp and hair.

In one embodiment, the cartridge 102 has a product identification tag 154 (FIG. 1) that can communicate operating instructions of the device 100a based on the particular formulation contained in the cartridge 102. The device 100a may include a product identification tag reader 156 (fig. 1) capable of reading the product identification tag 154 and processing the coded signals into instructions for operation and control of the device based on the particular formulation. Product identification tags include, for example, bar codes, 2-D bar codes, RFID, and the like. The product identification tag is encoded with a machine-readable signal that communicates the device settings for the particular formulation. Different formulations may have different device settings. For example, the product identification label may include a heat or vacuum setting, as well as a dispenser setting from a liquid to a fine, medium, or coarse droplet. 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 to the scalp and hair.

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

The dispenser 112 may dispense one or more formulations in the form of a fine mist or liquid through the tip 108 (or bristles or comb). In one embodiment, dispensing the formulation in the form of a mist or liquid allows the device to also change the viscosity of the formulation being dispensed. In one embodiment, the dispenser 112 includes a compressor, pump, or ultrasonic generator to generate mist from the formulation. In the case of a pump or compressor dispenser 112, such a dispenser 112 causes air or formulation to flow at high velocity, which pushes the formulation through a fine nozzle designed for atomization at the opening 130. In the case of a pump or compressor dispenser, a single dispenser 112 may be placed in the device 100 a. The outlet of the compressor or pump dispenser 112 is then directed through a system of conduits to each of the tines 108 and exits the nozzle at an opening 130.

In one embodiment, the dispenser 112 is an ultrasonic sprayer having an ultrasonic generator in contact with the formulation, wherein the frequency of the ultrasonic waves is sufficient to generate a mist. The ultrasonic sprayer also includes a "grid" sprayer having a vibrating grid just touching the surface of the formulation to create a mist. Any form of ultrasonic injector may use a piezoelectric element.

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

When the device 100a is operated, the electrostatic charger 152 may create a positive or negative charge on the scalp or hair or both to attract or repel the formulation to the charged area. In one example, the positively charged region is created by repelling electrons from the region, while in another example, the negatively charged region is created by attracting electrons to the region. The electrostatic charging may be performed by contact electric charging, induction electric charging, or the like. In one example, electrode 150 is connected to a high voltage source to induce an electrostatic positive or negative charge.

In another example, the hair formulation is charged while passing through the charging electrode 150. Negatively charged droplets of hair formulation are attracted to targets that may be at a lower potential.

In one embodiment, the apparatus 100a includes a vacuum system 114 having a vacuum generating motor and a collector. In one embodiment, the motor may be a variable speed motor. The motor induces an air flow into through an opening 132 at the tip 108. The air stream may carry the used formulation and any debris and oil rinsed from the hair by the formulation, which are then captured by the collector and the air is expelled from the device 100a. In one embodiment, the collector includes an annular vent 134, the annular vent 134 being located at the rear of the device 100a and surrounding the canister 102 (FIG. 4). The vent 134 allows air flow out of the device 100a while used and debris is captured in the collector. In one embodiment, the collector is removable from the device 100a and is safe for the dishwasher to allow cleaning in the dishwasher. In one embodiment, the surface of the collector that is in contact with the formulation used is coated with a hydrophobic or hydrophilic material to facilitate cleaning of the collector.

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

In one embodiment, the apparatus 100a includes a light processing system 146. In one embodiment, the light processing system includes one or more light emitting diodes 146 (LEDs), the LEDs 146 being capable of generating light over a wide range of the electromagnetic spectrum. In one embodiment, phototherapy has been used on the scalp to treat skin conditions. In one embodiment, phototherapy has been used to stimulate the cells of hair follicles. However, phototherapy has other benefits. In one embodiment, the phototherapy is performed by light emitting diodes 146 (LEDs), the light emitting diodes 146 being capable of generating electromagnetic energy over a broad range of wavelengths (at a single wavelength, such as a laser LED, or at multiple wavelengths over a broad range). For example, the intensity of light generated by the LED may be varied by controlling the current.

In one embodiment, the LEDs 146 comprise one or more III-V (GaAs) based LEDs capable of emitting electromagnetic radiation having wavelengths in the range from green visible to near infrared. In one embodiment, the LEDs 146 comprise one or more group III nitride blue LED solid state emitters capable of emitting electromagnetic radiation having wavelengths in the range from ultraviolet to blue visible light.

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

In one embodiment, the use of different LEDs that produce different wavelengths of light may be used to provide different treatments for the scalp and hair.

In one embodiment, the device 100a includes a haptic system 158. The haptic system may include a vibratory massager. In one embodiment, the haptic vibratory massager may include an electric motor that rotates an eccentrically placed weight that generates vibration according to a rotational speed. In one embodiment, the vibrotactile massager may include an electromagnetic coil and a permanent magnet that generate vibrations according to a period of a power source. In addition, other techniques may be used in the haptic system 158 to create one type of haptic actuation or feel of influence, including ceramic piezoelectric actuators, shape memory alloys, and shape memory polymer actuators, electrostatic forces, electroactive polymer actuators, piezoelectric motor actuators, and pneumatic actuators.

In one embodiment, the apparatus 100a includes one or more sensors. In one embodiment, one or more sensors are used to measure one of device distance, device speed, or device direction relative to the scalp or hair. In one embodiment, speed and direction are used to detect a "brush" technique for moving back and forth. In one embodiment, the apparatus 100a includes a contact sensor 160. The contact sensor 160 may indicate whether the tip 108, brush, or comb is in physical contact with the skin and hair. In one embodiment, the device 100a includes a proximity sensor 162. The proximity sensor 162 may indicate a distance from the sensor to the surface of the skin and hair. In one embodiment, the contact sensor 160 and the proximity sensor 162 may be placed at or near the end tips of one, more than one, or all of the tines 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 top of the head rather than on the back and left-right sides, the device 100a is typically held in different orientations. The dual and tri-axis accelerometers 164 are used to track the orientation of the device 100a from which position can be determined. Although accelerometer 164 is shown on tip 108, the accelerometer may be placed anywhere on device 100 a.

In one embodiment, the contact sensor 160 comprises an open or short circuit detector or a dielectric sensor. An open circuit detector may refer to an open circuit detector for detecting open (open circuit) continuity in electrical transmission. The short circuit detector may refer to a low resistance detection. Dielectric sensors may also be referred to as capacitive detectors, which can detect changes in dielectric constant. In one embodiment, the contact sensor 160 may be a sensor that detects contact or lack of contact of a single tip 108 (or bristle or comb). 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.

In one embodiment, the proximity sensor 162 may be an optical sensor, such as an infrared sensor or a camera, or both a camera and an infrared sensor. In one embodiment, an infrared sensor or a camera sensor or both may be positioned at various locations throughout the device 100 a. In one embodiment, the camera may 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, such as capacitive, ultrasonic, or Doppler sensors, may also be employed.

In one embodiment, accelerometer 164 is used to determine the position of device 100a (or a position associated with the head), the direction of device 100a, and the movement of device 100 a. In one embodiment, accelerometer 164 may be used in combination with other sensors, including magnetotelluric sensors (i.e., compasses) and gyroscopes. A gyroscope is a sensor that detects angular velocities around three axes and is capable of detecting rotation of an object. In addition, the geomagnetic sensor can determine the direction in which the device 100a faces.

In one embodiment, the apparatus 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 on a printed circuit board, or all of the circuits may reside on a single chip. The controller 148 may include at least a microprocessor core and a memory. The hardware can be designed for small hand-held devices. The microprocessor may be implemented as a plurality of processors that work cooperatively in parallel and in series to execute instructions in accordance with preprogrammed logic.

The controller 148 receives signals from sensors (e.g., contact sensor 160, proximity sensor 162, and 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 an analog signal that is converted to a digital signal by an analog-to-digital converter circuit before being stored and processed by the controller 148.

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

The controller 148 converts and interprets the signals from the sensors to represent the spatial condition of the device 100a, for example, the signals may be interpreted to indicate contact or non-contact with the device 100a, 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 preprogrammed instructions based on one or more signals. The instructions may be encoded in hardware or software. The instructions relate to whether and how to alter the operation of the one or more processing systems based on the signals from the sensors.

In one embodiment, each processing system 112, 152, 114, 144, and 146 has a processing scheme that specifies what processing should be provided based on real-time spatial conditions of the device 100 a. In this manner, controller 148 sends command signals to processing systems 112, 152, 114, 144, and 146 to adjust the treatment as the user moves device 100a to different areas of the scalp and hair. The controller 148 builds its instructions on the current (real-time) detected spatial conditions of the device 100 a. The spatial conditions may be related to the contact, distance, and location and orientation of the device 100a with the hair and scalp. The treatment regimen may be provided as any tabular data or function that correlates the area or distance to the scalp or hair with the treatment conditions. For example, the hair dryer may be controlled such that the air temperature varies in proportion to the distance the device 100a is away from the hair. In such an example, the treatment plan is air temperature as a function of distance or in table data, the table has rows for each temperature setting and columns for each distance setting, wherein the intersection of the rows and columns provides the treatment temperature for the spatial condition (distance in this example). The processing schemes for other processing devices may be set in a similar manner and based on other spatial conditions.

Instructions corresponding to each processing scheme may be stored inAny type of computer readable medium or computer storage device, and may be stored on and executed by one or more microprocessors. The instructions may be stored in a high-speed memory, such as EEPROM, flash memory, RAM, or other programmable non-volatile memory. The instructions may 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.

The processing scheme of the dispenser 112 based on the spatial conditions of the apparatus 100a may include: for example, the nature of the dispensed formulation is changed from liquid to mist depending on whether the formulation is directed at the scalp or into the hair, or the direction of the formulation being sprayed is changed or stopped by sensing the position of the device 100a relative to the hair or not sensing any hair. The treatment regimen also takes into account the type of formulation to be dispensed, i.e., whether the formulation is skin or scalp treatment or hair treatment. When the device 100 holds more than one cartridge, the device 100a may be configured to dispense a different formulation based on detecting movement of the device from one location to another, where the treatment regimen requires dispensing a different formulation at the second location.

The treatment regimen of the electrostatic charger 152 based on the spatial condition of the device 100a may include changing the electrostatic parameter 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.

The processing scheme of vacuum 114 based on the spatial conditions of apparatus 100a may include: the device 100a moves away from the skin or scalp to increase the vacuum based on the force of the vacuum being reduced by contact with the skin or scalp.

The processing scheme of blower heater 144 based on the spatial conditions of apparatus 100a may include: the force and temperature of the air is reduced based on contact with the skin or scalp and the device 100a is moved away from the skin or scalp to increase the blowing force and temperature.

The processing scheme of the light system 146 based on the spatial conditions of the apparatus 100a may include: some phototherapy is turned on based on contact with skin or contact with hair, power of the phototherapy is increased or decreased based on distance, or the phototherapy is turned off when no distance is contacted or exceeded where the phototherapy is ineffective. In one embodiment, a different light emitting diode may be illuminated based on detecting movement of the device from one location to another location, and the processing scheme invokes a different LED based on the second location.

Fig. 7 is a flow chart illustrating one embodiment of the operation of the device 100a, the device 100a changing or adjusting the operation of the hair or scalp treatment system based on the spatial conditions of the device 100 a.

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

In one embodiment, when the apparatus 100a is used for more than one process, i.e., the apparatus 100a has more than one processing system 112, 152, 114, 144, 146, the user may select the processing system in block 702. Block 702 may be omitted if device 100a has a single processing system. From block 704, the apparatus 100a proceeds to block 706.

In block 706, the apparatus 100a reads a processing scheme based on the selected processing system. Here, "reading" may refer to accessing or storing the processing scheme in a manner that may be used by the controller 148. The processing scheme may be stored in a memory of the controller 148. The processing scheme specifies the processes delivered by the processing system based on the changing spatial conditions of the device. Spatial conditions may refer to one or more conditions indicating contact or non-contact with the device 100a, distance from the device 100a, and position of the device 100a relative to the scalp and hair. The treatment systems 112, 152, 114, 144, 146 may change the treatments delivered by the treatment systems 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 block 706, the apparatus proceeds to block 708.

In block 708, the device 100a receives the sensor data in real-time and interprets the data to determine the spatial condition of the device 100 a. For example, spatial conditions that may be determined from the sensor include: with or without contact with device 100a, the distance of device 100a from the scalp and hair, and the position of device 100a relative to the scalp or hair. From block 708, the apparatus 100a proceeds to block 710.

In block 710, the device 100a compares the current spatial condition of the device 100a with a preprogrammed process recipe. From block 710, the apparatus 100a proceeds to block 712.

In block 712, the device 100a adjusts the processing system according to the processing scheme for the current spatial condition of the device 100 a. For example, if the selected treatment system is a formulation dispenser 112, the treatment regimen for the dispenser 112 may use a different setting or formulation for contacting the scalp (for the root of hair) and a different dispensing setting or formulation where the device 100a is moved farther from the scalp. For example, the formulation may be dispensed as a liquid when the device 100a is in contact with the scalp, and as the distance from the scalp increases, the dispenser 112 decreases or applies the formulation as a finer and finer mist. The treatment regimen for the blower and heater 144 may require minimal heat and airflow settings when contact with the scalp is detected, and the treatment regimen may require a gradual increase in temperature and airflow as the distance of the device 100a from the scalp or hair increases. The scheme for light treatment system 146 may require that the LEDs be turned on only when device 100a is in contact with the scalp and turned off if there is no contact or distance increases beyond the effective range of light treatment. The treatment regimen for the LEDs may require different wavelengths of LEDs to be illuminated depending on the area of scalp detected by the device. The instructions to change the processing systems come from a controller 148 in communication with each processing system.

When the device 100a is set to off, e.g., no movement is detected within a predetermined amount of time as determined by the accelerometer, the device 100a may be powered down or in a standby mode.

The use of the device 100a has minimal impact on hair style and the overall shape of the device 100a is familiar to other hair applications (e.g., hair dryers), resulting in a simple and intuitive use of the device 100 a. Furthermore, the device 100a does not require contact with the hair formulation by hand. The device 100a adds functionality that makes operation simpler, adapting the process to the specific spatial location of the device will minimize wastage and avoid dispersing mist into air that may be inhaled.

Fig. 8 and 9 illustrate an embodiment of the device 100b having brush heads 602, 1702 instead of the tips of fig. 1-5, wherein like numerals designate like components. In one embodiment, the body style of device 100b is similar to the body style of device 100a, and the differences are explained herein.

In one embodiment, the tips 602, 1702 are arranged in concentric circles on the brush. In one embodiment, tips 602 and 1702 may perform the function of tip 108 and have additional functionality.

Referring to fig. 10, another embodiment of a device 100c is shown, the device 100c having tips arranged in a comb configuration, wherein like numerals represent like parts. In one embodiment, the body style of the device 100c is similar to the body style of the devices 100a, 100b, and the differences are explained herein. In one embodiment, the tips 802 for the comb configuration are similar in material and construction as compared to the tips 602, 1702 shown in fig. 11, 12, 13, and 14, however, the difference is: comb tips 802 may be arranged in a single row.

Referring to fig. 16 and 17, another embodiment of a device 100d is shown, the device 100d having tips arranged in an in-line configuration with the body, as compared to fig. 8 and 9, wherein like numerals refer to like parts. In one embodiment, the body style of device 100d is similar to the body style of device 100a, and the differences are explained herein.

Fig. 11, 12, 13 and 14 illustrate embodiments of tips 602, 1702, 1100 and 1200 that may be used with the various embodiments of the devices 100b, 100c and 100d shown in fig. 8, 9, 10, 16 and 17.

In one embodiment, the bristle tips 602, 1702, 1100, and 1200 are configured to be able to dispense two different formulations from the tips. In one embodiment, tips 602, 1702, 1100, and 1200 have cavities that extend the entire length of the tips. Tips 602, 1702, 1100, and 1200 are at least one diameter in length. However, tips 602, 1702, 1100, and 1200 may be configured in length as several diameters, and thus the ratio of width to length may vary from 1 to 20 or even more. Tips 602, 1702, 1100, and 1200 may be flexible or inflexible. The separate chambers allow one or more formulations to be delivered through each chamber without mixing. The formulations may be separated in the respective chambers until the formulations leave the chambers. Dispensing of the formulation may be achieved by configuring each chamber with an opening along the length of the chamber or only at the end of the chamber or both along the length and end of the chamber.

In an embodiment, the chambers are depicted as half cylinders and full cylinders, but the chambers may have any cross-sectional shape. Furthermore, in an embodiment, the tips 602, 1702, 1100, 1200 and the first and second cavities forming them may be electrically conductive, thereby being configured as positive and negative terminals to further provide microcurrent or electrostatic charging treatments to the scalp and hair. In addition, there are other uses for the conductive tips 602, 1702, 1100, 1200 when the first and second cavities are connected to positive and negative terminals of a power source or the first and second cavities are connected to positive and negative sense terminals.

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

Referring to fig. 11, in one embodiment, the tip 602 is configured to connect a first hollow half cylinder 604 to a second hollow half cylinder 606 along a length. The first half cylinder 604 and the second half cylinder 606 may be made of a conductive material. In one embodiment, the first half cylinder 604 and the second half cylinder 606 are separated by an electrical insulator 608. Here, although the overall shape of the tip 602 is a "cylinder," the tip 602 may have any cross-sectional shape, including elliptical, rectangular, square, or any other polygonal shape, in accordance with the present disclosure.

Fig. 11 further illustrates that the tip 602 may have an opening 904 on the outer periphery. Hollow half cylinder 604 has a first opening 904 along the length of the exterior and hollow half cylinder 606 has a second opening 906 along the length of the exterior. In one embodiment, the openings 904, 906 may be formed by laser cutting holes (perforations) along the length of the tip 602.

In one embodiment, the tip 602 may omit the opening along the tip length, and the tip 602 is provided with an opening only at its distal end in order to use the tip 602 for treatment of the scalp. In this manner, two different formulations may be delivered from the tip 602 via the half cylinder 604 and half cylinder 606.

In one embodiment, the end of the tip 602 comprises a perforated flat or domed disc 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 disks, the half cylinders 604 and 606 may be fully open at the ends. Either configuration allows for dispensing of the formulation from the end or along the length of the tip 602 or along both the length of the tip and the end.

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 and the other half cylinder as a negative conductor terminal.

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 that can be actuated by an electric current to control the direction of movement of the tip 602.

Referring to FIG. 12, in one embodiment, tip 1702 is constructed by inserting a first hollow small diameter cylinder 1704 into a second hollow large diameter cylinder 1706. In one embodiment, the first cylinder 1704 is coaxial with the second cylinder 1706. The first cylinder 1704 may be referred to as an inner cylinder and the second cylinder 1706 may be referred to as an outer cylinder. Here, although the tip 1702 is in the shape of a "cylinder," the tip may have any cross-sectional shape, including oval, rectangular, square, or any other polygon, in accordance with the present disclosure.

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

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 that can be actuated by an electric current to control the direction of movement of the tip 1702.

In one embodiment, the chambers in the dual chamber configuration of the tips 602, 1702 may be made of or embedded with shape memory material or piezoelectric material that are actuated in opposite directions from each other, depending on which chamber is actuated to allow positive and/or negative actuation about a central location. For example, these materials may exist in the form of polymers, ceramics, and alloys. In one embodiment, the shape memory material and the piezoelectric material may be fabricated as coils, and do not have to be cavities. The coil may 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 via an AC or DC power source having positive and negative terminals connected to the shape memory material or the piezoelectric material.

In FIG. 12, the inner cylinder 1704 has a first opening 1004 that appears outside of the outer cylinder 1706; however, the openings 1004 may be connected by the outer cylinder 1706 such that the openings are 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 exterior, 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 thus 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. Insulation may be required between the inner 1704 and outer 1706 columns for electrical insulation. In either configuration, two different formulations may be delivered from the tip 1702 via the inner cylinder 1704 and the outer cylinder 1706.

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, the end of the tip 1702 comprises a perforated flat or domed disc having a small opening 1710 in the first inner cylinder 1704 and an opening 1708 in the second outer cylinder 1706. In an embodiment, unlike the tray, the inner cylinder 1704 and the outer cylinder 1706 may be fully open at the ends. Either configuration allows for dispensing of the formulation from the end or along the length of the tip 1702 or along both the length and end of the tip.

In one embodiment, when the tips 602 and 1702 are made of a conductive material, one of the posts 604 or 606 and 1704 or 1706 of each of the tips 602 and 1702 may serve as a positive terminal while the other may serve as a negative terminal for conducting electrical charge. This allows for powering devices such as LEDs or sensors.

Fig. 13 shows a tip 1100, similar in construction to tip 602, made of electrically conductive first hollow half-cylinder 1104 and electrically conductive second hollow half-cylinder 1106 placed side-by-side but electrically insulated from each other, wherein first half-cylinder 1104 is designated as the positive or negative terminal and second half-cylinder 1106 is the opposite polarity terminal to first half-cylinder 1104. An electrically insulating material or coating may be added between the first hollow semi-cylinder 1104 and the second hollow semi-cylinder 1106 for electrical insulation. 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 that is powered by the two half cylinders acting as terminals through contact with the positive and negative terminals.

Fig. 14 shows a tip 1200 that is similar in structure to tip 1702, made of an electrically conductive first hollow inner cylinder 1204, the first hollow inner cylinder 1204 being placed within an electrically conductive second hollow outer cylinder 1206 or coaxially within the second hollow inner cylinder 1206, wherein the first inner cylinder 1204 is a positive or negative terminal and the second outer cylinder 1106 is a 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 insulation. A power source is connected to the first inner column 1204 and the second outer column 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 two posts serving as terminals through contact with the positive and negative terminals.

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

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

In one embodiment, LEDs 1102 and 1202 may be used to process, cure a recipe, or indicate a device state (i.e., an operational mode or state of charge).

The LEDs may be any type of single wavelength (laser LEDs) or range of wavelengths. In one embodiment, the LEDs 1102, 1202 are capable of generating light over a wide range of the electromagnetic spectrum. In one embodiment, phototherapy has been used on the scalp to treat skin conditions. In one embodiment, phototherapy has been used to stimulate the cells of hair follicles. For example, the intensity of the light produced by the LEDs 1102, 1202 may be varied by controlling the current.

In one embodiment, LEDs 1102, 1202 comprise one or more group III-V (GaAs) based LEDs capable of emitting electromagnetic radiation having wavelengths in the range from green visible to near infrared. In one embodiment, LEDs 1102, 1202 include one or more group III nitride blue LED solid state emitters capable of emitting electromagnetic radiation having wavelengths in the range from ultraviolet to blue visible light.

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-370 nm. In other embodiments, LEDs 1102, 1202 emit electromagnetic energy in a wavelength range from about 200nm to about 2000nm, including wavelengths in the ultraviolet range (about 350 nm) and near infrared (about 1200 nm).

Referring to fig. 15, one embodiment of an apparatus 100b is schematically represented to illustrate major components, wherein like numerals represent like components described herein.

In one embodiment, the apparatus 100b includes a power supply 118. The device 100b may be powered by Alternating Current (AC) or Direct Current (DC). In one embodiment, the device 100b is powered by a general household alternating current that powers the device 100b by means of an electrical cord (not shown). In one embodiment, the device 100b is powered by direct current, such as a rechargeable battery that may be charged by plugging into a household alternating current outlet. The dc power supply device 100b allows the device to be used without being retained or in the vicinity of an electrical outlet.

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

In one embodiment, the cartridge 102 has a product identification tag 154 (FIG. 1) that can convey operating instructions of the device 100b based on the particular formulation contained in the cartridge 102. The device 100b may include a product identification tag reader 156 (fig. 1) capable of reading the product identification tag 154 and processing the coded signals into instructions for operation and control of the device based on the particular formulation. In addition to the above description, the product identification tag may also include dispenser pattern formations such as flat fans and cones, wide and narrow, solid and hollow, flow and fog.

In one embodiment, the hair formulation includes a cationic, anionic or zwitterionic polymer and the 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 act as complex molecules that block the charged interactions between the charged materials and their interactions with the hair fibers to allow more efficient charged interactions to occur.

Considering that hair holds an electrical charge (typically negative at neutral pH), this charge may be affected by the presence of electrically charged materials (e.g. materials described above) in the formulation, as they are applied to the hair, allowing for better and more efficient attraction/deposition or repulsion and assisted removal.

The dispenser 112 may dispense one or more formulations in a mist or liquid or any form therebetween through the tip 108 and the tips 602, 1702, 802, 1100, 1200. In one embodiment, the dispenser 112 includes a compressor, pump, or ultrasonic generator to generate mist from the formulation. In the case of a pump or compressor dispenser 112, such a dispenser 112 causes air or formulation to flow at a high velocity, thereby pushing the formulation through a fine nozzle designed for atomization at the opening 130. In the case of a pump or compressor dispenser, a single dispenser 112 may be placed in the device 100 b. The outlet of the compressor or pump dispenser 112 is then directed through a system of conduits to each of the tines 108 and exits the nozzle at an opening 130.

In one embodiment, the dispenser 112 is an ultrasonic sprayer that generates mist or vapor to dispense the formulation. This has the advantage of gentle dispersion of the formulation to reduce the amount of waste and improve control of coverage. In one embodiment, the injector uses an ultrasonic generator in contact with the formulation, wherein the frequency of the ultrasonic waves is sufficient to generate a mist. The ultrasonic applicator also includes a "grid" applicator having a vibrating grid that just contacts the surface of the formulation to create a mist. Any form of ultrasonic atomizer may use a piezoelectric element.

In one embodiment, the dispenser 112 is operated by depressing the switch 106 (fig. 1 and 2). In one embodiment, the switch 106 is placed on the front side of the upper portion of the handle 104 to allow for operation with the index finger. In one embodiment, the switch 106 is a momentary switch, with the default position being an open position. The momentary switch need only be activated once, regardless of the length of activation, to dispense a measured amount of the formulation. Keeping the momentary switch 106 depressed for a longer period of time does not dispense more formulation than a 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.

In one embodiment, the apparatus 100b includes an electrostatic charger 152. The electrostatic charger may create a positive or negative charge on the scalp or hair or both at the target area. 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 prongs 602, 1702, 802, 1100, and 1200. Suitable conductive materials for tips 602, 1702, 802, 1100, and 1200 may include: such as copper, nickel, stainless steel, aluminum, or any alloy thereof.

In one embodiment, the apparatus 100b includes a microcurrent generator 1158. The micro-current generator 1158 provides a voltage between positive and negative terminals (GND) to apply a small amount of current (micro-current) in a given frequency range to an area of skin or hair. In one embodiment, the amount and frequency of electrical stimulation may be within the scope of electrical processes that occur naturally in tissues and cells. For example, microcurrent therapy has stimulated hair growth, healed injured tissue, and skin regeneration through stimulation of collagen and increased blood flow. In one embodiment, the generation of the 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.

In one embodiment, tips 602, 1702, 802, 1100, and 1200 are connected to a microcurrent generator 1158. Tips 602, 1702, 802, 1100, and 1200, which are made of conductive material, allow one of the posts of the tips to act as a positive terminal, which can be used to provide micro-current to the scalp, where the scalp acts as a Ground (GND) path, which also includes the scalp and skin and tissue placed between the negative terminal in contact with the hand (e.g., on handle 104 of device 100 b). In one embodiment, a micro-current may be applied between a plurality of tips, one of which serves as a positive terminal and the other of which serves as a GND terminal.

In one embodiment, tips 602, 1702, 802, 1100, and 1200, which are made of conductive material, also allow the tips to function as sensors. In one embodiment, one of the posts of each of the tips 602, 1702, 802, 1100, and 1200 may serve as a positive terminal while a second post of the same or a different tip serves as a negative terminal. In one embodiment, the impedance between any positive terminal and any negative terminal may be measured to determine the scalp moisture level at a particular point or more generally region.

In one embodiment, the impedance may be measured from different tips to determine the scalp moisture level in a wider area.

In one embodiment, the impedance between the positive or negative terminal and the scalp (via the conductive return path to the handle) may 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 formulation treatment and vacuuming system, the scalp is being treated and if the device is not directly operated on the scalp, the vacuum runs the risk of drawing hair.

In one embodiment, the tips 602, 1702, 802, 1100, and 1200 are connected to the electrostatic charger 152. In one embodiment, the electrostatic charger 152 is used to create a positive or negative charge on the scalp or hair or both to attract or repel the formulation to the charged area. Tips 602, 1702, 802, 1100, and 1200 are conductive to allow the tips to act as electrodes. In one example, the positively charged region is created by repelling electrons from the region, and in another example, the negatively charged region is created by attracting electrons to the region. The electrostatic charging may be performed by contact electric charging, induction electric charging, or the like.

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

In one embodiment, the apparatus 100b includes a vacuum system 114 having a vacuum generating motor and a collector 116. In one embodiment, the motor may be a variable speed motor. The vacuum motor 114 is connected to impeller blades that force air flow into through the vacuum inlet opening 132 at the tip 108, or in the case of tips 602, 1702, 802, 1100, and 1200, one of the cylinders may be used for vacuum. The motor directs the air flow through opening 132 at tip 108 or one of the cylinders of tips 602, 1702, 802, 1100, and 1200. The air flow may carry the used formulation and any debris and oil rinsed from the hair by the formulation, which is then captured by the collector 116 and the air is expelled from the device 100b. In one embodiment, collector 116 includes an annular vent positioned at the rear of device 100b. The vent allows air flow to leave the device 100b while the used and debris is captured in the collector 116.

In one embodiment, the vacuum motor 114 is operated by a multi-position, multi-function selector switch 110 (FIG. 4). For example, the selection switch 110 may be a slide switch or a dial switch having more than two positions, or a push button switch having more than two positions. In one embodiment, the vacuum selector switch 110 includes settings for off and more than one vacuum speed setting, e.g., high and low. In one embodiment, a vacuum switch 110 is placed on the rear side of the lower portion of the handle 104, for example, to allow for thumb operation. The vacuum switch 110 may be isolated for uninterrupted vacuum. The light emitting diode 118 may be used to illuminate a selected location. The selector switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch may replace the selection switch, wherein the default position of the momentary switch is the off position and the momentary switch must be depressed to activate the vacuum motor. In one embodiment, the apparatus 100b includes both a vacuum selection switch and a momentary switch, wherein the momentary switch is used to operate the vacuum motor when depressed and set at a speed on the selection switch.

In one embodiment, the apparatus 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 on a printed circuit board, or all of the circuits may reside on a single chip. The controller 148 may include at least a microprocessor core and a memory. The hardware can be designed for small hand-held devices. The microprocessor may be implemented as a plurality of processors that work cooperatively in parallel and in series to execute instructions in accordance with preprogrammed logic.

Instructions to control the dispenser 112, the electrostatic charger 152, the micro-current generator 1158, and the vacuum 114 may be stored in a controller memory. The 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. The instructions may be stored in a high-speed memory, such as EEPROM, flash memory, RAM, or other programmable non-volatile memory.

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

In one embodiment, the controller 148 may be connected to one or more tips to function as the positive and negative terminals of the micro-current generator 1158.

In one embodiment, the controller 148 may be coupled to one or more tips to act as electrodes for the electrostatic charger 152.

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 100 b.

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

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

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

In one embodiment, the controller 148 may turn on the LEDs 1102 and 1202 based on predetermined instructions. For example, some formulations may require the application of light of a particular wavelength. The controller 148 may be used to control the LEDs 1102 and 1202 to provide phototherapy treatments. The controller 148 has instructions for determining the wavelength and power to be applied to the phototherapy.

In one embodiment, the controller 148 may control the amount of formulation dispensed by the dispenser 112. For example, the controller 148 may turn on the pump or compressor to achieve a predetermined amount of time associated with a particular amount of formulation. In one embodiment, the dispenser 112 uses a positive displacement pump, and thus the volume of each rotational displacement of the pump can be measured with an encoder. The controller 148 may shut down the pump when the rotation of the pump is equal to the volume of formulation to be dispensed.

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 a simple and intuitive use of the device 100 b. The device 100b may improve the current use of aerosol dry shampoos. The device 100b dispenses a controlled amount of the formulation such that when a user combs or brushes hair, the formulation slides onto and into the hair. The device 100b, in contrast to an aerosol sprayer, can spray more than is needed and produce a large cloud covering the outside area of the user's head.

Fig. 16 and 17 are schematic views of one embodiment of a device 100d, which device 100d may be fitted with a plurality of different tips. The device 100d may be used to clean hair that can be used with dry-cleaning hair water formulations, which have additional functionality by activating the tips individually for dispensing, sensing, massaging, and other uses. In one embodiment, the device 100d uses a brush or comb structure that relies on a combination of mechanical and chemical actions to deposit the desired formulation for cleaning, remove the formulation with unwanted particles, and further provide additional cosmetic or health attributes. The intuitive motion provides a familiar gesture that is easily incorporated into current cosmetic and hair care procedures. Further, the device 100d may include various types of hollow conductive or non-conductive tips (602, 1702, 1100, or 1200) arranged in a brush or comb configuration. The brush arrangement is shown, however, the device 100d may be configured with tips in a comb arrangement, i.e., a single row. However, tips arranged in a brush configuration allow for various advantages, such as individual actuation of the tips for applying one or more treatments, dispensing or massaging using only some but not all of the tips.

In one embodiment, the device 100d includes a massaging tip that is individually controlled by an actuator in XYZ motion. The tips only individually dispense a precisely measured volume of scalp product (by using an open/short or dielectric skin contact sensor) when in contact with the scalp. The individually activated tips spray the hair product (dry shampoo or hair dye) in a tightly controlled fashion (i.e., in a flat fan-like fashion). The personalized scalp and hair products are stored in a replaceable cartridge. The addition of the camera can determine the hair density, tone and dryness associated with scalp and hair conditions. The addition of LEDs can further treat the hair, promote camera imaging, and be used for formulation curing.

In one embodiment, the device 100d releases hair and/or scalp products as a vapor cloud (mist) by ultrasonic waves (similar to a household humidifier). The milder dispersion of the product reduces the amount of waste and improves control of coverage. This solution, in contrast to aerosol sprayers, can spray more than necessary and create a large cloud covering the area outside the user's head.

In one embodiment, the multi-purpose device 1100 is described as having a separately controlled tip for dispensing formulations and other uses.

In one embodiment, each tip is configured 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 washer. With respect to geometry only, each tip is a cylindrical chamber divided longitudinally into two or more isolated chambers, or two or more isolated cylinders fixed longitudinally to each other.

In one embodiment, the tip, which serves as the positive terminal, may be used to provide additional functionality to the tip. In one embodiment, micro-currents may be provided to the scalp, where the scalp serves as a GND path that also includes skin and tissue between the scalp and a negative terminal that is placed in contact with the hand, such as on the handle 104 of the device 100 d. The tip may provide a micro-current to the scalp, where the scalp acts as a conduction path between any positive terminal and any negative terminal. Alternatively, a micro-current may be applied between a plurality of tips, one of which serves as a positive source and the other of which serves as GND.

In one embodiment, the impedance between the positive and negative terminals may be measured to determine the scalp moisture level. Alternatively, the impedance between the plurality of tips may 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 if 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 if it is not directly operated on the scalp, the vacuum runs the risk of pulling hair.

An LED may be placed at the end of the tip and powered by two terminals. If the LED power is large, the heat dissipation may be absorbed (dissipated) by the conductive material. The LED at the end of the tip will deliver more energy to the scalp than the LED at the base and/or delivered through a long fiber path. The LED may be used to process, cure the formulation, or indicate the device status (i.e., operational mode or charge status).

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 separate opening at the end of the tip may be used.

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

In one embodiment, the tip is conductive allowing for a variety of options, for example, the conductive tip may be used with a microcurrent generator, or the conductive tip may be used as a sensing instrument to detect skin contact, or the conductive tip may be used to power a Light Emitting Diode (LED) for phototherapy, or the conductive tip may be used to provide vibration in one to three axes.

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 may be dispensed from only these tips to form a particular 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 the dispensing feature.

In one embodiment, the device 100d is shaped in a well-known familiar hair application pattern to motivate trust and confidence in the device, thereby enabling intuitive use and posture when using the device.

Referring to fig. 16 and 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. The control buttons may also be located on the handle.

Referring to fig. 17, on the back side, the device 100d may include a smaller diameter cylindrical housing 136 that receives a removable cartridge 102 containing a hair or scalp treatment formulation. The device 100d allows the cartridge 102 to be easily exchanged to provide a different formulation. Cartridge 102 may be configured as a refillable cartridge or a disposable cartridge. In one embodiment, the device 100d may be configured to hold more than one cartridge 102, where each cartridge may be filled with a different formulation for a different process. Alternatively, some applications may use two or more different formulations, which require the application of two formulations to achieve the desired treatment.

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

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 the central portion 138. The brush head 140 is part of the device 100d holding the tip 602, 1702, 1100 or 1200. In one embodiment, the brush head 140 is stationary relative to the device and does not actuate 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 the formulation from some individual tips, but not others. This allows some tips to be "on" while others are "off" to create different spray patterns from the brush head.

In one embodiment, the brush heads 602, 1702, 1100, 1200 are arranged in concentric circles on the brush head 140. In one embodiment, the tips 602, 1702, 1100, 1200 are configured to be capable of dispensing two different formulations. In one embodiment, the tips 602, 1702, 1100, 1200 have cavities that extend the entire length of the tips. The tips 602, 1702, 1100, 1200 are at least one diameter in length. However, the tips 602, 1702, 1100, 1200 may be configured in length as several diameters, and thus the ratio of width to length may be from 1 to 20 or even more. The tips 602, 1702, 1100, 1200 may be flexible or inflexible. The tips 602, 1702, 1100, 1200 may also be connected to the brush head 140 in a flexible manner. Separate chambers allow one or more formulations to be delivered through each chamber without mixing. The formulation may separate within the respective chamber until the formulation exits the chamber. Dispensing of the formulation may be achieved by configuring each chamber to have an opening along the length of the chamber or only at the ends of the chamber or along both the width and ends of the chamber. Furthermore, each chamber in the tip may have a valve or other means to control dispensing from only one chamber or two chambers. Controlling the dispensing of the formulation from only certain tips on the brush head enables the dispensing to be performed in a variety of modes, such as cone spraying, fan spraying, etc.

Referring to fig. 18, one embodiment of an apparatus 100d is schematically represented to illustrate a primary system.

In one embodiment, the apparatus 100d includes a power supply 128. The device 100d may be powered by Alternating Current (AC) or Direct Current (DC). In one embodiment, the device 100d is powered by a general household alternating current that powers the device 100d by means of an electrical cord (not shown). In one embodiment, the device 100d is powered by direct current, such as a rechargeable battery that may be charged by plugging into a household alternating current outlet. The dc power supply device 100d allows the device to be used without being retained or in the vicinity of an electrical outlet. The power supply 128 is configured to provide power to any system requiring 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.

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. Cartridge 102 may be removed from device 100d to be refilled or used for disposal and replacement with a new complete cartridge. Once emptied, the cartridge 102 may be replaced with a new cartridge filled with the same or a different formulation, or the cartridge may be refilled with the same or a different formulation. As shown in fig. 1, the cartridge 102 is inserted through the back of the device 100 d. The cartridge 102 is connected to supply scalp or hair preparation to the dispenser 112. In one embodiment, the device 100d may hold multiple cartridges, where each cartridge is filled with a different formulation, which may be dispensed to achieve different treatments and for different areas of the scalp and hair.

In one embodiment, the cartridge 102 has a product identification tag 154 (fig. 1) that can communicate operating instructions of the device 100d based on the particular formulation contained in the cartridge 102. The device 100d may include a product identification tag reader 156 (fig. 1) capable of reading the product identification tag 154 and processing the coded signals into instructions for operation and control of the device based on the particular formulation. Product identification tags, including, for example, bar codes, 2-D bar codes, RFID, and the like. The product identification tag is encoded with a machine-readable signal that communicates the device settings for the particular formulation. Different formulations may have different device settings. For example, the product identification label may include a dispenser arrangement from a liquid to a fine, medium, or coarse droplet. Product identification labels may also include dispenser patterns such as flat fan and cone, wide and narrow, solid and hollow, flow and fog. The product identification tag may also contain instructions for operating the 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 to the scalp and hair.

The dispenser 112 may dispense one or more formulations through the tips 602, 1702, 1100, 1200 in a fine mist or liquid or any form therebetween. In one embodiment, the dispenser 112 includes a compressor, pump, or ultrasonic generator to generate mist from the formulation. In the case of a pump or compressor dispenser 112, such a dispenser 112 causes air or formulation to flow at a high rate, pushing the formulation through the fine opening. In the case of a pump or compressor dispenser, a single dispenser 112 may be placed in the device 100 d. The outlet of the compressor or pump dispenser 112 is then directed through a conduit system to each individual tip.

In one embodiment, the dispenser 112 is an ultrasonic sprayer that generates a mist or vapor 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 control of coverage. In one embodiment, the injector uses an ultrasonic generator in contact with the formulation, wherein the frequency of the ultrasonic waves is sufficient to generate a mist. The ultrasonic applicator also includes a "grid" applicator having a vibrating grid that just contacts the surface of the formulation to create a mist. Any form of ultrasonic atomizer may use a piezoelectric element.

In one embodiment, both the ultrasonic generator and the vibrating mesh-like sprayer may use piezoelectric materials to generate vibrations at ultrasonic frequencies. In one embodiment, the same piezoelectric material used in the ejector may also be used to drive the haptic system. The haptic system may include a massage processing system, but may also include any system that provides a sensor experience, such as heating and associated ultrasonic processing. Atomizers may rely on frequencies that produce over 1 MHz. Ejectors capable of generating frequencies in excess of 1MHz may also be used to drive the haptic system to generate heat that may be used to treat skin and scalp alone or in conjunction with the dispensing of a formulation. Some ejectors may also rely on ultrasonic frequencies less than 1 MHz. In one embodiment, the ejector may be used to drive the haptic system to generate frequencies within a range designed to deliver the treatment compound to the skin and scalp in conjunction with the dispensing of the formulation. Thus, there are advantages when the same piezoelectric material used in the ejector system is used in the haptic system.

In one embodiment, each tip may include a valve at the inlet of one or both chambers. The valve has an actuator that opens and closes the valve. Each valve of each tip may be actuated to open or close independently of the other valves of the other tips. By opening or closing a valve at each individual tip, the formulation can be controlled to flow only from a selected tip in a controlled pattern (e.g., cone, flat fan, flow, multiple flows, pulses, etc.). Furthermore, having a valve controlling the dispensing from both chambers of the tip allows controlling the outflow of the formulation from one or both chambers.

Fig. 19 is a schematic view of the ends of tips 602, 1702, 1100, 1200. In one embodiment, the tips are arranged in a diameter-increasing circular pattern of small diameter 908, medium diameter 910, and large diameter 912. In one embodiment, only the valve of the tip connected by one of the circles 908, 910 or 912 may be opened, thereby dispensing the formulation in the small cone 908, the medium cone 910 and the large cone 912 to cover small, medium and large areas of the scalp or hair. The controller is instructed to open the tips in the modes to dispense the formulation according to the modes and to close the tips not in the modes. Actuation of the individual tip valves is not limited to circular modes. In one embodiment, the tip valve may be actuated in a linear mode. The line 914 connects only the tips that will be opened to dispense the formulation in the fan mode, while the remaining tips that are not in the linear mode will remain closed. Any combination of individual tips may be selected to dispense formulation from only some tips, not from others, to achieve different modes.

In one embodiment, the dispenser 112 is operated by depressing the switch 106 (fig. 1 and 2). In one embodiment, the switch 106 is placed on the front side of the upper portion of the handle 104 to allow for operation with the index finger. In one embodiment, the switch 106 is a momentary switch, with the default position being an open position. The momentary switch need only be activated once, regardless of the length of activation, to dispense a measured amount of the formulation. Holding the momentary switch 106 depressed longer does not dispense more formulation than a 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.

In one embodiment, the valves on tips 602, 1702, 1100, and 1200 are actuated if the individual tips selected for dispensing are in contact with the skin. In one embodiment, tips 602, 1702, 1100, and 1200, which are made of conductive material, allow the tips to function as contact sensors. In one embodiment, one of the posts in each of the tips 602, 1702, 1100, and 1200 may serve as the positive terminal while the second post of the same or a different tip serves as the negative terminal. In one embodiment, the impedance between any positive terminal of the tip and any negative terminal of the tip may be measured to determine whether one or more individual tips are in contact with the scalp (skin). In one embodiment, the impedance between any positive terminal and the scalp (via the conductive return path to the handle) may be measured/if the application requires scalp contact, it is useful to determine the impedance and contact; for example, in a formulation treatment and vacuuming system, the scalp is being treated and if the device is not directly operated on the scalp, the vacuum runs the risk of drawing hair.

In one embodiment, the impedance measurements may also be used to calculate scalp moisture levels at specific points or more generally areas. In one embodiment, the impedance may be measured from different tips to determine the scalp moisture level in a wider area.

In one embodiment, a contact sensor 1162 may be placed at the tip. In one embodiment, contact sensor 1162 includes an open or short circuit detector or a dielectric sensor. An open circuit detector may refer to an open circuit detector for detecting open (open circuit) continuity in electrical transmission. The short circuit detector may refer to a detection of low resistance. Dielectric sensors, also known as capacitive detectors, can detect changes in dielectric constant. In one embodiment, the contact sensor 1162 may be a sensor that detects contact or lack of contact of individual tips. In one embodiment, the contact sensor 1162 may indicate the amount of contact. An example of a contact sensor that can detect the amount of contact is a piezoelectric sensor.

In one embodiment, the apparatus 100d includes a massage module 1152. The massage module 1152 is any circuit configured to control actuation of any number of individual tips 602, 1702, 1100, and 1200 to vibrate. In this embodiment, the tip is individually controlled to vibrate as compared to the vibration of the entire brush head. The massage module circuitry may be located within the controller 148 or may be a separate component. The massage module 1152 circuit controls actuation of each tip in one to three axes (XYZ). The tip may be initially activated to vibrate by switch 1164. In one embodiment, each tip 602, 1702, 1100, 1200 on the brush head 140 has its own actuator to vibrate each individual tip in one to three axes. In one embodiment, the actuator may comprise a shape memory material or a piezoelectric material. As described above, the conductive posts may be formed of or embedded with shape memory material or piezoelectric material to actuate the vibration.

Referring to fig. 20, one embodiment of the tips 602, 1702, 1100, 1200 includes a first pair of actuators 1008, 1010 disposed on or embedded in a cylinder of the tip in a radially opposed position relative to one another. The actuators 1008, 1010 extend axially along the length of the tip. The actuators 1008, 1010 may be actuated one at a time to produce lateral motion, such as in the X-axis. The tip includes a second pair of actuators 1012, 1014 disposed on or embedded in the barrel of the tip in a radially opposite position to each other and 90 degrees from the actuators 1008, 1010. The actuators 1012, 1014 extend axially along the length of the tip. The actuators 1012, 1014 may be actuated one at a time to produce lateral motion, such as in the Y-axis. The actuators 1008, 1010, 1012, 1014 are coupled to a conductive substrate of the tip and when a voltage is applied to the piezoelectric material and the substrate, the actuators 1008, 1010, 1012, 1014 produce a contracting and bending motion in one direction by means of the transverse piezoelectric effect. In this way, lateral actuation in the X-axis and Y-axis is possible.

For vibrations in the Z-axis or up and down, the top end of the tip may rest against the shape memory coil 1016, and the shape memory coil 1016 may be actuated to vibrate up and down. Although one embodiment using piezoelectric material and shape memory material is shown, other configurations are possible based on the present disclosure. Piezoelectric materials may also be produced as tubes or stacks to cause up and down vibrations, while shape memory alloys may be provided as strips to cause lateral, bending or shearing movements of X-axis and Y-axis vibrations. Any combination of one or more piezos or shape memory alloys may be used to provide vibration to the tip in one to three axes.

In one embodiment, the apparatus 100d includes a vacuum system 114 having a vacuum generating motor and a collector 116. In one embodiment, the motor may be a variable speed motor. The vacuum motor 114 is connected to impeller blades that force air flow into through one of the cylinders of tips 602, 1702, 1100, and 1200. The motor directs the air flow through the tip opening. The air flow may carry the used formulation and any debris and oil rinsed from the hair by the formulation, which is then captured by the collector 116 and the air is expelled from the device 100d. In one embodiment, the collector 116 includes an annular vent positioned at the rear of the device 100d. The vent allows air flow to leave the device 100d while the used and debris is captured in the collector 116.

For example, the selection switch 110 may be a slide switch or a dial switch having more than two positions, or a push button switch having more than two positions. In one embodiment, the vacuum selector switch 110 includes an off setting and more than one vacuum speed setting, e.g., high and low. In one embodiment, a vacuum switch 110 is placed on the rear side of the lower portion of the handle 104, for example, to allow thumb operation. The vacuum switch 110 may be isolated for uninterrupted vacuum. The light emitting diode 118 may be used to illuminate a selected location. The selector switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch may replace the selection switch, wherein the default position of the momentary switch is the off position and the momentary switch must be depressed to activate the vacuum motor. In one embodiment, the apparatus 100d includes both a vacuum selection switch and a momentary switch, wherein the momentary switch is used to operate the vacuum motor when depressed and set at a speed on the selection switch.

The controller 148 has instructions for determining the wavelength and power to be applied to the phototherapy.

In one embodiment, the controller 148 has circuitry to control the amount of formulation dispensed by the dispenser 112. For example, the controller 148 may turn on the pump or compressor to achieve a predetermined amount of time associated with a particular amount of formulation. In one embodiment, the dispenser 112 uses a positive displacement pump, and thus the volume of each rotational displacement of the pump can be measured with an encoder. The controller 148 may shut down the pump when the rotation of the pump is equal to the volume of formulation to be dispensed.

In one embodiment, the controller 148 has circuitry configured to control the dispenser 112 to dispense a measured volume of the formulation through one or more tips only when the controller 148 senses that the tips are in contact with the scalp.
