    Description
    Title of the invention: MINIATURIZED ELECTRONIC BOX INTEGRATED IN ANY SOLE SOLE Technical field [0001] The invention relates to the field of footwear or more generally that of footwear. The invention relates more particularly to an electronic unit for connected shoe soles.
    More specifically, it is a biomechanical data measurement system consisting of two boxes each disposed in each of the two shoe soles of the same pair, intended to collect and use information on locomotion, the pattern of walk, posture or balance of the user, or very generally the gait, the run, or the activity thereof.
    PRIOR ART [0003] The soles, whether internal or external, or even the whole shoe essentially have the original role of protecting the foot from the ground. Their shape varies according to fashion and its vagaries to make room for a multitude of derivatives and functions.
    The shoes can be for relaxation, formal, sporting, medical, professional or more simply recreational use. Thus, a shoe mainly consists, on the one hand, of a sole in the lower part which protects the soles of the feet, more or less raised at the rear by the heel and, on the other hand, of the upper, upper part that envelops the foot. It can be limited to the ankle or be rising.
    The sole can be divided into two parts. An upper sole layer in direct contact with the wearer's foot and a lower sole layer in direct contact with the ground or more generally the external environment.
    [0006] A shoe can also include a removable internal sole. In this particular case, this sole is also composed of at least one upper sole layer and one lower sole layer.
    New technologies accompany new needs and the world of footwear is part of this movement. The development of electronics has led to the appearance of so-called connected soles and shoes, which have very diverse functions.
    Very generally, these connected soles or shoes can be autonomous and contain a rechargeable battery. They can be connected to an external terminal by a wired system or by a wireless connection.
    Among the functions offered by existing connected soles or shoes, we can cite the function of heating the foot to one or more given temperatures, determined by the manufacturer; we can also cite those, described in document US2017 / 0188950, equipped with pressure sensors and an accelerometer and which make it possible to deliver to a smartphone connected via Bluetooth statistics on the physical activities of their wearer such as the number of steps performed or how the foot is positioned during walking, etc.
    On the other hand, we can also cite connected soles or shoes capable of detecting land mines in the vicinity, by generating an electromagnetic field. To this end, the detection device is integrated into the sole or the shoe of its wearer. Equipped with a microprocessor and audio transmission, the system communicates wirelessly with a companion bracelet.
    In addition, we can also cite connected soles or shoes which allow their cushioning to be adapted to the rigidity of the surface on which the wearer is walking, or which offer an effective lacing device.
    There are soles using pressure sensors supposed to identify posture, but these technical solutions have never allowed to date to have a marketable and effective product. Our technology, based on accelerometers and gyroscopes combined with communication systems between soles and algorithms, allows tracking of posture, locomotion, walking / running pattern and balance.
    US2017 / 0241797 describes an apparatus intended for the user to count the steps and to distinguish the race from normal walking by means of a pedometer and an accelerometer. This device does not, however, provide information on parameters other than speed. In addition, the device contains only one pedometer and one accelerometer, which does not offer as much precision as the present device.
    US2017 / 303827 describes a device of connected soles comprising sensors for studying the gait of a person. Equipped with an accelerometer and a gyroscope, this device collects biomechanical data, which is exchanged between the two soles and transmitted to a terminal. However, the various elements of this device are scattered throughout the sole, in particular the pressure sensors which collect most of the data.
    EP 1970671 and WO 2011157870 each describe an intelligent shoe designed to allow its user to control different variables (distances traveled, time used, calories consumed ...) in order to control and improve his sports performance. This device, based on a single box, uses an accelerometer only and no gyroscope, and does not detect the walking pattern or posture.
    Finally, WO 0125726 describes a device installed on two shoes allowing the detection of the movement data of a person and the method of processing said data, in particular with a view to detecting the speed of the person. Dating from 1995, it does not use current sensors or the same electronic technology. In this device, the two soles do not communicate with each other.
    However, despite the variety of technological solutions offered, no user has access to soles or shoes allowing him to monitor his posture in general and his feet in particular (real-time monitoring during 'an effective activity, not simulated), posture which is indicative of changes in the state of health, physical and / or physiological balance.
    Furthermore, these devices based on the presence of numerous sensors distributed in the sole (e.g. pressure sensors) have a shorter lifespan and often a relatively high thickness which can limit the use of these soles. In addition, calculations are generally not performed in real time.
    In general, the state of the art characterized by these various devices only allows the user to have information on his performance or on the characteristics of his immediate external environment.
    Technical problem The aim of the invention is to remedy the drawbacks of the prior art. In particular, the object of the invention is to allow the user to access, particularly through the electronic unit installed in each of its connected soles, information on the exact posture of his feet and more generally on his gait or his activity. .
    Brief Description of the Invention The invention therefore relates to a system for analyzing and quantifying the posture and gait of a user, characterized in that it comprises a pair of soles each provided with a electronic unit, each unit comprising:
    - An inertial platform consisting of at least one accelerometer and at least one gyroscope, said inertial platform being configured to generate a set of data on the posture, the activity or the gait of a user of the pair soles - a data processing module configured to process the data collected according to predefined algorithms and generate information on the posture, activity or gait of a user of the pair of soles;
    - a data storage module configured to store the information generated by the processing module;
    - A means of communication configured so that the electronic unit of at least one of the soles is able to transmit the information generated on the user to the external terminal and / or to the second housing of a second sole ;
    - a source of energy.
    Such a system makes it possible to follow a user's approach reliably. Indeed, the presence of a pair of soles each comprising a housing protecting an inertial platform gives the possibility of independently monitoring the movement of each of the feet. The inertial platform will analyze, in at least three dimensions, posture, movements, locomotion, balance and the environment of the user, and more generally everything related to the activity of his feet or which will be qualified as his approach. The inertial platform will be able not only to note the different positions but also to identify deficiencies or anomalies that appear at the level of locomotion, pattern, or more generally of the user's walk. In addition, the present electronic unit bringing together all the electronic components necessary for autonomous operation, such as all the sensors, including calculation modules and an energy source, makes it possible to increase the robustness of the system. This box can advantageously be unique, compact and miniaturized.
    In addition, unlike the systems proposed in the prior art, the calculation is carried out here at the level of the sole by means of a data processing module which may correspond to the firmware (“firmware” in English terminology) an electronic card. In this way, the data is transformed almost in real time at the level of the electronic unit, compared then can then be transferred for their visualization on an external terminal. Such a system makes it possible to reduce the demand on the memory of the storage module and can then make it possible to increase the autonomy of the system.
    According to other optional features of the invention:
    the boxes are configured so that a first box receives the data from its sole and transmits them to a second box, which processes the data received by comparing them with its own data and generates information on the gait of the user or the posture of his feet, information which is then transmitted by one of the boxes to the external terminal in real time or in a delayed manner.
    each of the boxes contains an electronic card with an inertial platform, consisting of at least one accelerometer and a gyroscope, and which can be supplemented by other sensors, in particular a magnetometer, a barometer and an altimeter.
    each of the boxes, in addition to the electronic card and an energy source, can also be connected to a GPS and / or to all types of sensors, in particular physiological sensors, pressure sensors, temperature sensors or any air conditioning system placed in the sole.
    each of the boxes is designed so that it can communicate with the second box and / or directly with the external terminal in order to exchange its own information on the posture, movement and activity of his foot, of which it received the data via its inertial platform and the sensors of its sole.
    each electronic unit has at least two support pads.
    a first housing is distant from a second housing by a distance corresponding at least to the length of a wave, the antenna of the housing of the left sole being located furthest to the left with respect to the user, the antenna of the housing of the right sole being located furthest to the right with respect to the same axis, so as to optimize the level of transmission and reception of the signal.
    each of the electronic boxes has an outer casing, said outer casing essentially being made of a thermoplastic composite material allowing it to withstand high mechanical stresses (evaluated and tested under conditions of use - casing inserted into a sole or a shoe) corresponding to at least 100,000 impacts of 1000 N at a frequency of 1 Hz or 100,000 impacts of 3000 N at a frequency of 2.6 Hz, said device being moreover resistant to dust and humidity at a level at least IP56 .
    the system according to the invention makes it possible to associate one or more Android, IOS or other applications with secure sharing of data with the user via the external terminal.
    the energy source of the housing can be a rechargeable battery, the recharging of which can be carried out using different technologies:
    by charger, with a connector flush with the sole;
    with a mechanical recharging device integrated into the sole, such as for example a piezoelectric device capable of supplying electrical energy from the step; with a contactless device, for example by induction.
    Other advantages and characteristics of the invention will appear on reading the following description given by way of illustrative and nonlimiting example, with reference to the appended figures which represent:
    Figure 1, a longitudinal sectional view from above of two soles each containing a cavity which will give way to a housing, each of the antennas of the housings being located on the outer edge opposite each foot, according to one embodiment of the invention.

    Description of the invention [0031] The term "sole" means an object which makes it possible to separate the foot of the user from the ground. A shoe may include an upper sole layer in direct contact with the wearer's foot and a lower sole layer in direct contact with the ground or more generally the external environment. A shoe can also have a removable insole.
    In the following description, the "gait" within the meaning of the invention corresponds to the posture, the movements, the locomotion, and the balance of the user. Balance corresponds to postural balance linked to the stability of the body and more particularly to the stability of a user's center of gravity.
    The “quantification of the gait” corresponds, within the meaning of the invention, to the attribution of one or more values, for example a score, a classification or a note to a trajectory or a movement of a foot of a user. This quantification of the approach makes it possible to obtain one or more biomechanical parameter values representative of the approach and can be carried out on the basis of numerous scales of different sizes (e.g. 1, 5, 10, 100) linear or not.
    By “biomechanical parameter” and more particularly by “parameter calculated from movement data”, is meant within the meaning of the invention the result of a transformation of the measured trajectory of a foot of a user into one or more values.
    By "model" or "rule" or "algorithm" is meant within the meaning of the invention a finite series of operations or instructions for calculating a value through a classification or partitioning of data within previously defined groups Y and assigning a score or prioritizing one or more data within a classification. The implementation of this finite sequence of operations makes it possible for example to assign a label Y to an observation described by a set of characteristics or parameters X thanks for example to the implementation of a function f capable of reproducing Y having observed X.
    Y = f (X) + e where e symbolizes noise or measurement error By "pattern" is meant the way in which the user unrolls his foot during his walk or run.
    By "treat", "calculate", "determine", "display", "transform", "extract" "compare" or more broadly "executable operation", within the meaning of the invention, an action performed by a device or processor unless the context indicates otherwise. In this regard, operations relate to actions and / or processes of a data processing system, for example a computer system or an electronic computing device, which manipulates and transforms the data represented as physical quantities (electronic ) in the memories of the computer system or other devices for storing, transmitting or displaying information. These operations can be based on applications or software.
    The terms or expressions "application", "software", "program code", and "executable code" mean any expression, code or notation, of a set of instructions intended to cause data processing to perform a particular function directly or indirectly (eg after a conversion operation to another code). Examples of program code may include, but are not limited to, a subroutine, function, executable application, source code, object code, library, and / or any other sequence of instructions designed for execution on a computer system.
    By “plastic composite”, within the meaning of the invention, a multicomponent material comprising at least two immiscible components in which at least one component is a polymer (thermoplastic or thermosetting) and the other component can be a reinforcement such as a fibrous reinforcement.
    The term “thermoplastic polymer”, within the meaning of the invention, a polymer generally solid at room temperature, which can be crystalline, semi-crystalline or amorphous, and which softens during an increase in temperature, in particular after passing its glass transition temperature (Tg) and flows at a higher temperature. Examples of thermoplastics are, for example: low density polyethylene (HDPE), polyethylene terephthalate (PET) or polyvinyl chloride (PVC).
    The term "thermosetting polymer" means a plastic which is irreversibly transformed by polymerization into an insoluble polymer network.
    By "removable" is meant the ability to be detached, removed or disassembled easily without having to destroy fixing means either because there is no fixing means or because the fixing means are easily and quickly removable (eg notch, screw, tab, lug, clips). For example, by removable, it should be understood that the object is not fixed by welding or by another means not provided to allow the object to be detached.
    In this description and even before, the same references are used to designate the same elements.
    Existing devices or systems generally have a plurality of sensors (e.g. pressure sensors) distributed in the shoe and / or sole. Such a distribution of the sensors leads to a reduction in the robustness of the system. In addition, these devices or systems are generally intended to produce raw data which is then analyzed at an external terminal. Faced with these shortcomings, the inventor has developed a system 1 for the quantification of a user's approach as shown schematically in Figure 1.
    In addition, as a reminder, the two feet contain a quarter of all the bones of the human body. In each foot, it is possible to identify 26 bones, 33 muscles, 16 joints and 107 ligaments. The feet carry the weight of the body in a standing position and allow locomotion, ensuring a vital role in balance, cushioning and propulsion. The feet also perform several types of movements. In addition, the feet have almost 7,200 nerve endings, so that all diseases and other neurological disorders in particular are perceptible directly or indirectly in our feet and, on the other hand, can be detected from our way of to walk or to move.
    To pursue this objective, the invention consists of a stand-alone technology inserted in a compact and miniaturized case weighing a few grams, which is inserted in each of the two inner and / or outer soles of shoes of the same pair.
    The system 1 according to the invention comprises a pair 10 of soles and an external terminal 20.
    The soles 11, 12 usable in the context of the system 1 according to the invention can for example correspond to outer soles or to inner soles of shoes. These soles can be removable or be permanently integrated into the sole of the shoes. Preferably, the soles are removable insoles.
    Conventionally, the soles 11, 12 components of said pair 10 of soles, each include an electronic unit 100,101,102. As shown in Figure 1, the electronic unit 101,102 is preferably positioned at a middle portion of the sole.
    An electronic unit 100 according to the invention is detailed in FIG. 2. Weighing only a few grams and being of reduced size, this electronic unit 100 fits in a space-saving manner in any insole and / or exterior . This low volume limits the impact on user comfort and has the advantage of optimizing production costs by making it cheaper and easier to integrate this technology into the sole during the industrial process.
    The choice of material for this electronic unit is made to ensure its solidity and the possibility of inserting it into a sole. Indeed, it is necessary to be able to manufacture a product which can on the one hand, resist the weight of a person and, on the other hand, be easily inserted in a sole or a shoe. Combining miniaturization and resistance of the case is a real challenge: it was necessary to make many prototypes before determining the material which allows to insert such a case in a sole, without altering its comfort.
    Advantageously, each electronic unit 100 includes an outer casing 103, said outer casing essentially consisting of a material of the plastic composite type selected from: a thermoplastic composite material or a thermosetting composite material.
    The choice of a plastic composite material makes it possible to combine both lightness, efficiency of signal transmission and above all solidity.
    Thus, each electronic unit is preferably light and weighs less than 10 grams, preferably less than 8 grams and more preferably less than 6 grams. In addition, it may have a thickness of less than 5 mm, preferably less than 4 mm and more preferably less than 3 mm. This allows it to integrate easily into a shoe / sole without affecting the comfort of the user in his shoe. Finally, each electronic unit has less than 5 cm2 of surface on its largest face, preferably less than 4 cm2 and more preferably less than 3 cm2.
    Preferably, the outer casing 103 of the electronic unit 100 has an upper part 103a and a lower part 103b which are welded. Such welding, for example ultrasonic welding, makes it possible to increase the water resistance of the electronic unit. Alternatively, the upper part 103a and the lower part 103b can be separated by a polymer seal and held by removable fixing means. Thus, each electronic unit can include an outer envelope formed in two parts and a seal positioned between two parts of the outer envelope.
    Each electronic unit advantageously incorporates pillars or support pads 104 in order to reinforce its solidity, preferably one pad / cm2 to withstand the pressures and impact forces of the movements of the foot. The insertion of such studs allows the housing to better withstand the weight of a person.
    Preferably rounded in shape to increase its mechanical strength, it must be assembled in such a way as to maintain a perfect seal and make the interior containing the electronic card and the energy source protected from humidity and dust.
    Thus, preferably, the electronic unit 100 according to the invention comprises at least two support pads 104, more preferably at least three support pads 104 and even more preferably at least four support pads 104 .
    Advantageously, the electronic unit 100 includes an electronic card having at least one opening 105 allowing the passage of at least one support stud 104, preferably at least two openings 105.
    In addition, in order to further increase the robustness of the system, each electronic unit comprises a shock absorbing material such as polymer foam (e.g. polyurethane, polyether). According to one embodiment, the shock absorbing material has a density of between 20 kg / m3 and 50 kg / m3. Such a protective foam layer also isolates the card from vibrations and humidity.
    According to one embodiment of the invention, the electronic card is inserted in a compartment of the housing specially designed to receive it.
    According to another embodiment, the electronic unit 100 is formed by the encapsulation of its components. For example, the encapsulation may take the form of a coating coating or a resin (e.g. silicone, epoxy, polyurethane). The encapsulation of all the components (e.g. inertial platform, processing module ...) provides good insulation and thus combines good electrical properties with excellent mechanical protection.
    In addition, the electronic unit according to the invention comprises an inertial platform 110,111,112 configured to generate a set of data on the gait of a user of the pair 10 of soles.
    During the walk of a user, the inertial platform 110 acquires signals representative of a movement parameter (acceleration and / or speed, for example angular speed) of the foot along the axes X, Y, Z. In addition, this data can then be processed to generate at least one acceleration signal. The inertial platform consists for example of at least one accelerometer and a gyroscope. Preferably, it includes several accelerometers and gyroscopes.
    The electronic unit can also include one or more magnetometers so as to acquire three additional raw signals corresponding to the values of magnetic fields in three dimensions.
    Each electronic unit can also include other sensors, in particular an inclinometer, a barometer and an altimeter to benefit from increased precision.
    In addition, the electronic unit according to the invention comprises a data processing module 120,121,122 configured to transform all of the data generated using predefined algorithms.
    This processing module makes it possible to analyze in 3D the posture, the movements, the locomotion, the balance and the environment of the user, and more generally all that will be qualified as being his walk, from data collected by the inertial platform and any additional sensors placed in the sole.
    This processing module can be used to generate biomechanical parameters of the approach. Advantageously, the data processing module 120 is able to transform the data set into at least one biomechanical gait parameter, said biomechanical gait parameter being preferably selected from: posture, pronation, supination, impact force, impact zone, step length, contact time, flight time, lameness, propulsion force, balance and several other parameters relating to the user and describing his approach , his postures and his movements.
    In addition, the transformation by the data processing module can advantageously comprise the segmentation of the data into a plurality of phases. Preferably, the data processing module is able to segment a step into at least four phases such as: the impact phase (corresponds to the precise moment of the foot's contact with the ground), the support phase (takes place from the impact phase to the detachment of the heel from the ground), the propulsion phase (begins when the heel has left the ground and ends when the first toe has left the ground) and the flight phase (begins when the first toe has left the ground and ends when the heel touches the ground).
    More particularly, the cutting or segmentation of the pitch can make it possible to identify the main areas of support for the user. Thus, the system can be used to measure the shape of the step during walking or any other activity of the user in order to determine possible malformations of the feet and postures of the user.
    The information generated will then be transmitted to the second unit by transmitting signals which may be of the Bluetooth type.
    When an electronic unit is unable to communicate in real time with the other unit and / or with the terminal, it stores the information collected and will transmit it deferred when the exchange is again possible. This delayed transmission of the data collected is made possible thanks to the storage capacity of each of the electronic boxes.
    Thus, the electronic unit according to the invention comprises a data storage module 130,131,132, configured to store at least part of the transformed data and / or data generated by the processing module.
    In addition, the electronic unit according to the invention comprises a first means of communication 140,141,142 configured so that the electronic unit 100 of at least one of the soles is able to transmit at least part of the transformed data to a external terminal 20. This data can be transmitted in real time or deferred to an external terminal 20. The external terminal 20 can for example be a remote system such as a tablet, a mobile phone (“smartphone” in English terminology), a computer or a server.
    Advantageously, each electronic unit further comprises a second communication means configured so that the electronic unit 101 of a first sole is able to communicate with the electronic unit 102 of a second sole, and in that at least one data processing module 121,122 is configured to calculate, preferably jointly, data sets generated from the two flanges 11,12, and more particularly from the inertial platform, composing the pair 10 of flanges. Indeed, the calculation of certain biomechanical parameters of interest requires data from the two soles.
    The first and second means of communication are capable of receiving and transmitting the data over at least one communication network. Preferably the communication is carried out via a wireless protocol such as wifi, 3G, 4G, and / or Bluetooth. And in order to optimize the data transmission between the first and the second means of communication, the boxes will be positioned inside the soles so as to be as distant as possible from each other, the 2 antennas being distant each other at least the length of a wave (about 13 cm, taking into account current technology).
    Advantageously, due to its confinement inside a housing placed under the body of a person, the antenna must be disposed inside the housing on the side facing the outside of the sole. . This positioning of the antenna is essential insofar as laboratory tests have established that the signal emitted from a sole or a shoe is absorbed by 70% by the human body. This antenna must therefore be positioned on the periphery of the foot and oriented so as to always be able to transmit the signal to the external terminal and / or to the housing of the second sole.
    In addition, the electronic unit according to the invention comprises an energy source 150,151,152. The energy source is preferably of the battery type, rechargeable or not. Preferably the energy source is a rechargeable battery. In addition, it can be associated with a recharging system by movement or by external energy. The recharging system by external energy can in particular be a recharging system by wired connection or else a recharging system by induction.
    In addition, the electronic unit according to the invention may include a wired connection means 160, preferably protected by a removable tab. This wired connection means can for example be a USB or firewire port. This wired connection means can be used as mentioned above to recharge the battery but also to exchange data and for example update the firmware of the electronic card carrying the various components of the electronic unit.
    These various components of the electronic unit are preferably arranged on an electronic card 170 (or printed circuit). In addition, the different means and modules of the electronic unit 100 are shown separately in FIGS. 1 and 2, but the invention can provide various types of arrangement, for example a single module combining all of the functions described here. Likewise, these means can be divided into several electronic cards or else combined on a single electronic card.
    In addition, the system 1 includes an external terminal 20 capable of receiving data. The external terminal 20 is generally a tablet, a mobile telephone (“smartphone” in English terminology), a computer or a server. It may be able to transfer this data to a remote server 30. It is then for example possible to access this remote server via a web interface.
    Advantageously, a dedicated application is installed on this external terminal in order to process the information transmitted by the boxes and allow the user to interact with the invention.
    Advantageously, according to one embodiment of the invention, the two boxes will preferably be configured in a Main box and a Secondary box. The Main unit will receive data on the position and / or activity in which the Secondary sole is located; the Main unit will process this data and draw information from it in all circumstances (for example, when the user is in a kneeling position, soles raised more or less vertically, each of the units will notice that his sole is in a raised position more or less perpendicular to the ground; the Main unit noting that it is in the same position as the Secondary unit, it can deduce that the user is in a kneeling position).
    Therefore, even if the two soles are in different positions, the two boxes continue to detect the positions of each sole so as to record the changes in posture of the user. This continuous detection of the postures of the user makes it possible, by comparison over time, to accurately record the changes in walking, posture or physical, sporting or professional activity thereof, so that the device can also identify any possible anomalies, such as possible lameness.
    The box will therefore be able not only to note the different positions but also to identify deficiencies or anomalies which appear at the level of locomotion, balance, or more generally of the walk of the user.
    The Main unit will analyze and store the data collected and then transmit the information in real time or delayed to the terminal. Thanks to the storage module of each of the boxes, most of the data collected will be able to be stored as long as the boxes are not connected to an external terminal, so that there is no loss of data or user information.
    According to one embodiment of the invention, the Secondary unit can also transmit the data collected to an external terminal.
    In addition to the analysis of walking and the activity of its user, this invention aims to identify deficiencies or problems related to the posture of the feet. This posture is indicative of mechanical, physical or physiological problems of the user, especially when walking.
    From the posture of the foot and its movement, all kinds of information are measured by the electronic card located in the housing. The user may have an inappropriate gait, have irregular steps, an improper walking pattern, an undetected pronation or supination ...
    This box will be able to analyze the data relating to the postures of each of the two feet to detect several anomalies, perceptible by the simple analysis of the locomotion, the pattern or the balance of the user, or very generally the walking or the activity of this one.
