Monitoring of hair aggression , brushing pattern/movement,

Control the temperature and airflow of the hair dryer

Provide feedback (real - time or not) and teach users brushing/drying techniques

Improved brushing technique - allowing users to achieve the best drying / styling performance/results

Prevent / limit hair damage

Providing recommendations on personalized or suitable products and hairstyles

Provides refined ergonomics to achieve the highest compliance rates and improve monitoring and guidance performance

1 illustrates a system 100 according to one embodiment. The system 100 includes a hair dryer device 110 and a brush device 150 . The hair dryer 110 performs functions of a conventional hair dryer such as generating and discharging hot air from the outlet 112 . Brush 150 includes bristles 154 disposed about the axis of the brush (“round” hair brush type). However, additional known hair brush types can likewise be used.

In addition, the hair dryer device 110 and the brush device 150 include additional components. For example, the hair dryer device 110 further includes a temperature controller 114 and an actuator 116 . The thermostat 114 controls and regulates the temperature of the air emitted by the hair dryer. The actuator controls the shape of the airflow pattern and the airflow rate. An actuator may be a movable mechanical part capable of moving in an airflow and modifying its shape. Such airflow control is known in the art as evidenced by EP1779745 A1, which is incorporated herein by reference.

The hair dryer may further include a proximity sensor 118 preferably disposed near the outlet 112 of the hair dryer. The proximity sensor may be an optical sensor, such as an infrared sensor known in the art. However, other examples such as capacitive, ultrasonic or Doppler sensors may also be used.

In one embodiment, the hair dryer device 110 is configured to change at least one setting in the hair dryer based on the received sensed characteristic. In one embodiment, the hair dryer device 110 is configured to dynamically modulate at least one setting in the hair dryer based on the received sensed characteristic.

The hair dryer may further include a printed circuit board (PCB) 120 including communication and control circuitry such as a wireless RF communication interface for performing wireless communication with an external device (eg, the brush device 150 ).

The brush device may further include its own PCB 180 including communication and control circuitry, such as a wireless RF communication interface for performing wireless communication with an external device (eg, hair dryer 150). The PCB may further have motion detectors such as accelerators/gyrometers.

The brush device may also include a hair humidity sensor and a temperature sensor. Hair and humidity sensors are known and understood in the art.

As shown in FIG. 1 , between the brush device 150 and the hair dryer 110 , there may be a wireless object communication feedback loop enabled by communication between the wireless RF communication interfaces built into each device. In this feedback loop, the brush can sense the temperature when the hair dryer is operating and the humidity level of the user's hair and provide this feedback to the hair dryer. Based on this information, the hair dryer can adjust the temperature of the airflow and/or the shape of the mechanical element that controls the airflow shape, for example by adjusting the resistance of the heating element in the hair dryer, adjusting the fan speed, and/or controlling the airflow shape. Alternatively, the shape and/or speed may be adjusted.

2 shows an electrical block diagram of hardware components of a hair dryer according to an embodiment. Power from power source 204 is controlled by microcontroller/processor 203 . It will be understood that the electrical block diagram may be modified to adapt to other configurations in accordance with the principles disclosed herein.

In one example, communication interface (I/F) 205 may include circuitry and hardware for communicating with client device 120 . The communication interface 205 may include a network controller such as Broadcom's BCM43342 Wi-Fi, Frequency Modulation and Bluetooth combo chip to interface with the network. Hardware can be designed to reduce size. For example, the processor 203 may be a CPU as understood in the art. For example, the processor may be APL0778 from Apple Inc., or other processor types recognized by those skilled in the art. Alternatively, the CPU may be implemented in an FPGA, ASIC, PLD, or using discrete logic circuitry, as will be appreciated by those skilled in the art. In addition, the CPU may be implemented as a plurality of processors working cooperatively in parallel to execute the instructions of the process of the present invention described above.

In one embodiment, the hair dryer includes a user interface 206 , which may be in the form of an input button on the housing of the tool, or may be in the form of a touch-sensitive display, such as a capacitive or resistive touch screen display.

In one embodiment, the hair dryer includes an output indicator 202 , which may be in the form of a light (eg, LED light), an indicator on a touchscreen, or an audible output through a speaker.

In one embodiment, the hair dryer includes a memory 207 that stores software for controlling the hair dryer or for storing user data or other information.

In one embodiment, the hair dryer includes a position/motion sensor 208 that can detect the direction of the hair dryer being held by the user, which can also detect the movement and movement path of the hair dryer. In one embodiment, the position/motion sensor is at least one of a geomagnetic sensor and an acceleration sensor, or a combination thereof. For example, a three-axis geomagnetic sensor identifies the direction of the geomagnetism, or in other words, the geomagnetic vector Vt, given the current orientation (of its housing) of a styling tool housing the three-axis geomagnetic sensor. The 3-axis accelerometer determines the direction of gravity, or, in other words, the gravity vector G, given the current orientation (of its housing) of the styling tool housing the 3-axis accelerometer at rest. The gravitational vector G coincides with the downward vertical direction. The gravitational vector G can likewise be decomposed into Xs, Ys and Zs axis components.

Alternatively or additionally, a gyroscope may be used, which is a sensor capable of detecting angular velocity about the three axes Xs, Zs and Ys (roll, pitch and yaw) and detecting rotation of an object. Also, as described above, the geomagnetic sensor may determine the direction the object is facing based on the geomagnetic vector.

The hair dryer may include an actuator circuit 209 used to control the shape of a mechanical element that controls the airflow shape.

The hair dryer includes the proximity sensor 118 described above.

The hair dryer includes a thermal control circuit 210, which is used to control the heat by changing the resistance of the heating element in the hair dryer as described above.

The hair dryer also includes a fan control 211 which is used to vary the speed of the blower fan in the hair dryer as described above.

3 shows a diagram of an electrical block diagram of the hardware components of a hair brush according to one embodiment. Similar to the hair dryer described above, the hair brush includes a microcontroller/processor 303 , a power source 304 , a communication interface 305 , a user interface 306 , a memory 307 and a position/motion sensor 308 . do.

The hair brush may also include acoustic sensing circuitry 309, which may include a microphone to detect the dryness of the user's hair based on day-to-day energy and spectral acoustic fluctuations.

The hair brush may also include moisture sensing circuitry 311 . This circuit may be similar to that described in US Application Serial No. 13/112,533 (US Publication No. 2012/0291797A1), which is incorporated herein by reference. Alternatively, the moisture sensing circuit may rely on a Hall effect sensor to detect changes in magnetic fields, which changes are sensitive to moisture levels.

The hair brush may also include a force sensor 311 , which may be in the form of a load cell disposed between the head and the handle.

The hairbrush may also include an ambient temperature/humidity sensor 312 described above, which detects a local temperature or humidity in the vicinity of the hairbrush.

Additionally, the hair brush may include a conductive pin quill 313 embedded in the hair brush to detect whether the hair is wet or dry, or to detect contact with the user's hair.

The hair brush may also include an imaging unit 314 , which may be a camera disposed on the user's head or an exterior surface of the brush facing the hair while the user uses the hair brush. The imaging unit may optionally have thermal imaging capabilities for sensing thermal properties of the user's hair. The imaging unit may also include an illumination unit (eg, LED light) to aid in the imaging process.

As described above, the brush and the hair dryer are provided with means for communicating with each other, and the hair dryer is equipped with a calibrated control system to adapt the temperature and airflow according to the hair damage/aggression indicator and/or the user selected styling result. do. Thus, intelligence and algorithms built into or external to the brush and/or hair dryer can translate sensor recordings into adjustments in the hair dryer.

Figure 4a shows a general process performed between a hair dryer and a hair brush. In one process illustrated in FIG. 4A , communication pairing 401 is performed between two devices when they are within an acceptable wireless communication range of each other. Such pairing will depend on the type of communication protocol used and such protocols are well understood in the art. A user may use a hair brush, during which time the hair brush will perform any of a number of sensing operations as described above (step 402). The sensing operation need not occur while the hair dryer is being used simultaneously, and may be started and completed at any time based on receiving user input to initiate/end such sensing. The sensor record obtained by the sensing operation may be stored in memory (step 403) and/or communicated immediately to the hair dryer (step 404).

As shown in Fig. 4A, the hair dryer stores the sensor record received from the hair dryer, and performs processing and analysis of the sensor record (step 405). The hair dryer then adjusts the hair dryer based on the processing and analysis of the sensor recording (step 406).

In FIG. 4A , communication pairing need not occur before the user uses the hair brush to perform the sensing operation at 402 , but may occur any time before the hair brush sends a sensor recording to the hair brush.

Also, the hair brush need not necessarily perform processing and analysis of sensor recordings as shown in step 405 . In this situation, the hair dryer may transmit the sensor recordings to an external client device (eg, a smartphone or user computer) to control the performance of processing and analysis of the sensor recordings, as will be described in further detail below. Additionally, as shown in optional step 403', the hair brush may perform at least some processing and/or analysis on the sensor recording prior to sending the information to the hair brush.

4B illustrates an algorithm that may be performed by a hair brush according to an embodiment. In step 410, the hair brush detects a trigger for initiating a sensing operation. This trigger may be an intentional user input in the user interface of the hair brush to initiate one or more sensing actions. It is also possible to receive a trigger from the hair dryer itself. For example, when a communication pairing is established between the hair dryer and the hair brush, the hair dryer may transmit a signal to the hair brush to initiate a sensing operation. The transmission of this signal may be coupled to the user activating the blow operation of the hair dryer, or it may be based on a proximity sensor of the hair dryer detecting that the hair dryer is within range of the user's hair or hair brush.

In step 411, a sensing operation(s) is performed in step 411 . The type of sensing operation performed by the hair brush has been described in detail above. In step 412, the sensor data obtained from the sensing operation is stored in the memory of the hair brush as it is obtained. In step 413, the sensor data is sent to the hair dryer. Optionally, in step 414 , the hair brush may perform at least some processing and/or analysis of the sensor data before sending the sensor data to the hair dryer. At this time, the results of this processing and/or analysis will also be transmitted to the hair dryer together (or even without sensor data) in step 413 . This transmission may occur when data accumulates after a total amount of time, may occur periodically, may occur based on user input in the user interface of the hair brush, or may occur based on a request signal received from the hair dryer. can occur

4C illustrates an algorithm that may be performed by a hair dryer according to an embodiment. At step 420 , the hair dryer receives sensor data, which may occur when data accumulates in the hair brush after a total amount of time, as previously described, may occur periodically, or may occur as a user in the user interface of the hair brush. It may occur based on an input, or may occur based on a request signal received from the hair dryer, the request signal may be triggered by a user input in the hair dryer, or the user turns off the blowing operation (power of the hair dryer) can be based on the same event). In step 421, sensor data is processed or analyzed, which will be described in more detail below. In step 422, the hair dryer performs adjustment of settings for the hair dryer based on the processed/analyzed sensor data, which will be described in more detail below.

As described above, in step 421, the sensor data is processed or analyzed by a hair dryer (or other device described below). The specific type of analysis will depend on the type of detection made and the analysis goals.

For example, when using a hairbrush alone or with a hair dryer, the user's brushing pattern and movement may be determined based on a combination of data obtained from force/effort sensors, accelerometers and gyroscopes, magnetic compasses, contact sensors, and proximity sensors. can From this data the next brushing pattern and movement can be determined.

The sensor data may also be determined based on a combination of data obtained from the sensed ambient temperature and humidity, the temperature and humidity of the hair in contact with the brush, conductance sensor, thermal camera, microphone, contact sensor, proximity sensor, and force/effort sensor, hair characteristics. May be used to assess the level of /damage/aggression or risk of hair damage. From this data the following hair characteristics/damage/aggression or risk levels can be determined.

In one embodiment, the client device 510 is configured to operate a software application or set of software modules to receive and transmit communications with the hair dryer 110 . In one example, the software application may send a protocol or target profile to the hair dryer 110 and receive data from the hair dryer 110 to track usage in real time.

5B shows various examples of client device 120 including mobile device 522 , wearable electronic device 524 , television or magic mirror 526 , network router 528 , and personal computer 529 . .

Wireless signal 520 may be any suitable signal, such as WIFI, Bluetooth, electromagnetic signals including near field, or any other signals such as optical and acoustic. Each client device, including the appliance, may communicate with each other via an Internet connection to a wireless Internet access point via an 802.11 wireless connection or via a physical connection to an Internet access point, eg, via an Ethernet interface. Each connected device may communicate wirelessly with the other device, for example via a Bluetooth connection or likewise other wireless means.

5C is a diagram illustrating an example of a system 550 for enhancing the optimal performance of the hair dryer 110 according to an example. System 550 includes at least a hair dryer and a client device. Optionally, system 550 may further include one or more external servers 542 implemented as part of a cloud computing environment and in communication with system 550 via the Internet. One or more external servers 542 may store user data, hair products, products such as hair dryers or brush accessories, protocols and routines, tutorials, and other third-party services according to examples.

The user interface or client device may display a tutorial on how to use the hair dryer. The user interface can create and download protocols for therapies or routines. The user interface may map, track usage, and compare the tracked usage with protocols, regimens and routines. The user interface may calculate a score based on the tracked usage. The user interface may store the score and tracked usage of the hair dryer in the memory of the client device. The user interface can be used to purchase any product related to the hair dryer. For example, a hair dryer may be used in conjunction with a combination of styling products or chemical compositions used to treat the user's hair, and the client device determines the particular styling product or composition and process to be used, based on the desired result entered by the user. It is possible to output a recommendation at which stage of the process to use them.

As an initial step, the client device collects information about the user's desired outcome. In one example, a user may use a client device to browse a database of images representing various hairstyles. In another example, a user may enter a keyword search into the client device to find a desired appearance. A client device can either store the search results locally or connect to an external system or server to access the database or search results.

After the user has found a desired appearance to achieve using the hair dryer, he or she can access a tutorial for using the hair dryer to achieve the target appearance. The tutorial may be in text format, clear picture format, video format, or audio-only format.

In addition to using the tutorial, the user can connect the client device 510 with the hair dryer via a wireless connection (eg, Bluetooth or Wi-Fi connection) to receive real-time feedback while using the hair dryer, report later or provide feedback. You can record the usage of the hair dryer for this purpose.

For example, the hair dryer can communicate which settings are currently being used with the hair dryer.

For example, while using the hair dryer, a motion sensor on the hair dryer may output a detected movement of the hair dryer as feedback to the client device. The client device is configured to compare the detected movement with predetermined movement data to provide a real-time performance result to the user or output an instruction for the user to perform correction.

In another example, the temperature sensed by the hair brush and delivered to the hair dryer may be communicated to the client device. The client device is configured to compare the detected temperature with the predetermined temperature information to provide an alert to the user when the detected temperature exceeds a predetermined threshold.

For example, the timer of the hair brush may provide the measured time information to the client device. The client device is configured to compare the measured time with the target time to provide an output to the user for an amount of time remaining for a particular action of using the hair dryer or to provide an alert to the user when a time target has elapsed. The target time may depend on the routine, the style being achieved and the current stage of the process, and may have different durations for different stages. The client device is configured to receive input from the user to generate a customer profile based on a personal characteristic of the user. For example, a client device might ask, "Should I dye my hair or not?", "Is my hair thick or thin?" and "Is your hair straight or curly?" to the user. Customer profiles can be used to select specific tutorials or data sets to use when measuring performance from hair dryers and brushes. The client device may recommend or avoid recommending or suggesting a particular hair style depending on the assessed hair type, level of damage or other parameters.

The client device may also have a camera function that can be used to provide input to the customer profile. For example, the camera may take an image of the user's hair to determine whether a desired appearance is possible, or may make additional recommendations to the user based on a characteristic or color of the hair or skin.

Alternatively, the client device may interface with known spectroscopy tools to analyze the user's hair. Alternatively, the client device may interface with known chemical measurement tools to determine the chemical and structural properties of the user's hair. In one embodiment, the client device is configured to maximize user personalization and safety. The client device may alert the user if a setting is not recommended for the user's hair type. The client device may query whether the user's hair is color treated (including bleached), highlighted, keratin-treated, or relaxed.

The client device may receive as input the level of moisture or porosity or hair (which may be assessed by a stylist or by a moisture sensor on a styling tool).

The client device may provide an alert if the hair is not ready to receive additional heat, such as when the moisture sensor of the hair brush detects too high a degree of dryness.

The client device may provide instructions to pretreat the user's hair prior to applying heat. The client device can advise whether the initial temperature is correct for the style the user is trying to achieve because different temperature levels are suitable for different hair quality levels.

The client device may have automatic settings or controls, such as providing automatic temperature control from the client device from the phone.

The client device is configured to upload data about the user to an external system or server (eg, a cloud-based system). Such data may include user profiles, usage of styling tools, or performance results when using styling tools. The client device may provide an option to keep user data anonymous.

Further, the circuitry of the client device may be configured to operate a discovery protocol that enables the client device and the hair dryer to identify each other and negotiate one or more pre-shared keys, which further enable the hair dryer and the client device to be encrypted and Allows the exchange of anonymized information. The discovery protocol may also allow the client device and the hair dryer to exchange treatment regimen information according to a specific type of hair dryer or hair brush or based on a specific detected accessory.

The client device may use the camera function to provide sharing features, where the user may upload photos taken before and/or after using the styling tool. Uploaded photos can be used to receive feedback from professional hair stylists or other users. In one embodiment, the uploaded photos may be uploaded directly to the social media platform.
