Description

The invention relates to a sports shoe for the practice of skiing, and a method for data technology initialization and electronic condition detection of a sports shoe for the practice of skiing.

The W02007 / 015908A2 describes a system for displaying the athletic mileage of a running athlete on electronic devices. The signals from a step sensor in the sole of the running shoe, a heart rate or blood pressure sensor on the runner's body, and other sensor data are transmitted wirelessly to an electronic adapter device. The adapter device, which receives at least the step signals, can be mechanically connected and disconnected via a connector to the data interface of a standard display device and transfers the data to be visualized by means of the display device via this data interface. The adapter device and the display device, which can be formed by a standard mobile phone, a PDA, an MP3 player, a wrist watch and the like, are worn on the runner's body and are provided for evaluating the run performance of the runner. This known system is only of limited use in connection with the practice of skiing.

DE9417953U1 describes an insert for a ski boot. This insert should serve as a learning aid for the execution of the right swing. It consists of a flat and flexible insert that covers the heel area. A cell filled with a liquid is arranged in this insert part, a cell which is responsive to pressure and which is connected via cable to a power supply and a controller outside the ski boot is arranged in the cell. The controller in turn is connected to a device for generating acoustic signals, in particular a stereo headphone. This device is only partially satisfactory as a support for the practice of skiing.

A generic sports shoe in combination with an electronic control system is also described in AT517933A9, which publication goes back to the applicant.

[0005] WO 2017/185050 A1 discloses in one embodiment a generic sports shoe. Furthermore, a sensor detection system (SAS) is disclosed which comprises a plurality of pressure sensors which are connected by means of flexible electrical lines to an electronic evaluation unit for signal conditioning, data acquisition, storage, analysis, feedback, communication and optionally for detection functions. The sensor detection system (SAS) can also be set up to store information which can be transmitted to the electronic evaluation unit. This can include serial numbers, footwear properties, clothing or object properties, position information of the sensor detection system (SAS) on the footwear, item of clothing or object - such as left, right, top, bottom -, number, type and configuration of the sensors, calibration data, user data and the like.

[0006] EP 2 556 795 A1 describes a system and a method for providing feedback to a user about his or her running style or about the running technique. The system uses a pressure sensitive surface to record a pressure center curve that the user's foot exerts on an underlying surface during a stride period. In the case of a forefoot or midfoot landing, the gait line moves backwards in relation to the sagittal plane. Two time stamps are determined from a reverse gear line. The first time stamp T1 is the time the foot touches the ground. The second timestamp T2 is the time when the gait line reaches the most backward position. A load time dT is determined from the time difference between these two time stamps. Accordingly, the user can be provided with a feedback signal about his running activity.

[0007] DE 10 2010 012 037 A1 describes a device for providing a trai

AT 521 347 B1 2020-01-15 Austrian patent office nings feedback in golf, consisting of wireless pressure measurement soles for insertion in the golf shoe and a terminal or terminal for outputting an acoustic and / or visual feedback based on the measured pressure data. The pressure sensors in the pressure measurement soles are calibrated to determine the pressure exerted. The calibration value can be stored in the terminal or in the sole so that suitable calibration values are available the next time the training system is started. This calibration takes into account the aging effects of the pressure measurement sole, different golf shoes and other effects. Such calibration measures are only partially satisfactory, especially for sports shoes for the practice of skiing.

[0008] WO 2006/106516 A2 describes a rehabilitation system which comprises a shoe to be worn by a patient with an insole. At least one force sensor is set up to carry out force measurements. A control unit is provided to receive the force measurements and to convert them into a weight measurement.

The object of the present invention was to overcome the disadvantages of the prior art and to provide a device and a method with which it is possible to an optimized, electronic detection of the respective use or application states of a sports shoe achieve and at the same time to achieve a high cost-effectiveness of the electronic recording or control system for the end user.

This object is achieved by a product and a method according to the claims.

A sports shoe according to the invention, which is designed according to a particularly practical application as a ski shoe for practicing skiing, comprises a shoe body provided for receiving the foot of a user, at least one pressure sensor on or in the shoe body for electronic detection of pressures acting on the shoe body or forces, and an electronic signal processing device or a plug interface to an electronic signal processing device, which electronic signal processing device is provided for signal or data processing of the electrical pressure signals generated or provided or derived by the at least one pressure sensor. An electronic storage device is attached to or in the shoe body, which electronic storage device is provided for storing at least one shoe and / or user-specific calibration data relating to the at least one pressure sensor. These calibration data thus stored on the shoe side are provided for reading out and processing by an electronic signal processing device which can be brought into functional interaction with the sports shoe or is in functional interaction.

It is also provided that the electronic storage device comprises shoe and foot-specific calibration data with respect to the left foot and the left sports shoe of a user if this sports shoe is the sports shoe to be worn on the left, and that the electronic storage device comprises shoe and foot-specific calibration data regarding a user's right foot and right athletic shoe when this athletic shoe is the right athletic shoe. A control technology, evaluation technology and / or logistically advantageous embodiment can thereby be created.

The measures according to the invention also have the advantage that the cooperating system of sports shoe and user can be coordinated with one another as optimally as possible and, after appropriate coordination, the representative or essential comparison or calibration data are stored or stored directly on the sports shoe , In contrast to storage in the electronic signal processing device or in a remote storage area, for example a cloud storage with remote access, this brings the advantage of high or at any time availability of the user and / or shoe-specific calibration data, which is necessary for an adequate detection of the pressure signals of the pressure sensors or for a meaningful evaluation and evaluation of the pressure signals are essential.

2.24

AT 521 347 B1 2020-01-15 Austrian Patent Office [0014] In particular, this means that, despite weak or poor mobile radio connections or despite non-existent remote access to certain storage devices, for example on the Internet, the most exact possible electronic determination and evaluation of the respective pressure distribution conditions or usage behavior of the sports shoe. This is particularly useful in connection with ski boots for practicing skiing in alpine terrain.

A particular advantage of the measures according to the invention also lies in the fact that an electronic signal processing device can be coupled with a basically indefinite number of sports shoes according to the invention. In particular, the electronic signal processing device can be designed to be portable with regard to a plurality of sports shoes or can be designed for use by a plurality of users. An owner of a sports shoe according to the invention can therefore either borrow or rent the electronic signal processing device without problems from a sports retailer, or share the electronic signal processing device with family members or friends. After the electronic signal processing device can be transmitted or used by several people as required, the investments in the personal, electronic evaluation or training system can be kept as low as possible. In particular, the costs for the personal, user-specifically calibrated sports shoe can be kept relatively low after the additional costs for the implementation of the at least one pressure sensor and the electronic data memory for storing the shoe or. user-specific calibration data are comparatively small. In addition, through these measures, the relatively individual sports shoe, which can be adapted to the shape of the foot or to the needs of the respective user, can be upgraded at a later point in time with a system-compatible, but generally transferable, electronic signal processing device if required will be permanently equipped at a later point in time. This favors the spread of a corresponding electronic training system or the digital evaluation system that can be implemented with it in relation to sports-relevant data or in connection with usage-dependent loads of a sports shoe according to the invention.

A particular effect of the measures according to the invention is that legal data protection provisions can also be taken into account in a relatively simple and economically advantageous manner.

According to an expedient measure, at least one electrical line and / or at least one contact interface is formed, via which the electronic storage device can be connected or connected in an electrically conductive manner to an electronic signal processing device. This enables a functionally reliable and, at the same time, cost-effective implementation of a basically permanent coupling, or a coupling that can be activated and deactivated as required, with a structurally independent or, if necessary, removable and transferable signal processing device.

Alternatively, it can also be provided to design the electronic storage device as a sub-component of a transponder unit, in particular as an RFID / NFC tag, the transponder unit being operable without batteries and being provided for wireless data transmission to a communication-compatible, electronic signal processing device. After an electronic signal processing device is typically battery or battery-powered and such an electronic signal processing device is preferably arranged in close proximity to a sports shoe according to the invention, a relatively energy-saving, radio-technical communication link can also be established between a signal processing device and the shoe-side storage device with the adjustment or Calibration data. As a result, the ease of use can be further increased or the handling for establishing a data communication connection can be accelerated and / or simplified.

3.24

AT 521 347 B1 2020-01-15 Austrian Patent Office [0019] Provision can further be made for the pressure signals from the shoe-side pressure sensors or the data derived therefrom to be transmitted wirelessly to a communication-compatible electronic signal processing device.

It is also expedient if the electronic storage device is formed by a non-volatile, programmable storage unit, in particular by an EEPROM memory. Such storage devices are relatively small and also lightweight and they can store the relevant data for sufficiently long periods of time without the need to supply electrical energy.

In addition, it can be advantageous if the electronic storage device is permanently fixed in or on the sports shoe, in particular embedded or glued therein. Especially when the sports shoe is designed as a ski shoe, it is expedient if the electronic storage device is fastened in or on the relatively soft-elastic inner shoe of the ski shoe. This minimizes the risk of damage to the electronic storage device, which can be applied to a flexible, film-like or textile-like carrier layer. In addition to increasing the robustness of the electronic storage device, its functional availability can also be improved after the electronic storage device cannot be misplaced or lost. The permanent, non-detachable fixation of the electronic storage device to the sports shoe also ensures that the latter is not transferred to other sports shoes or to other users and the quality of the signal acquisition and data evaluation can thus be kept high.

High-quality signal or data acquisitions can be carried out if the calibration data are formed by correction factors or compensation parameters, which correction factors or compensation parameters are provided for signal or data compensation or attenuation of fluctuation influences, which fluctuation influences on batch-specific fluctuations of the at least one pressure sensor , based on manufacturing tolerances of the athletic shoe, on production or age-related fluctuations in athletic shoe stiffness, and / or on user-specific, individually different pressure loads compared to the at least one pressure sensor. As a result, particularly meaningful usage information can be generated, with which the athletic behavior of the operator can be analyzed and ultimately improved.

[0023] The object of the invention is also achieved by a method for data-technical initialization and electronic condition detection of a sports shoe, in particular a ski shoe for practicing skiing. Such a sports shoe comprises a shoe body provided for receiving the foot of a user, at least one pressure sensor on or in the shoe body for the electronic detection of pressures or forces acting on the shoe body, and an electronic signal processing device or an interface to an electronic signal processing device. This electronic signal processing device is provided for signal or data processing of the pressure signals generated or provided or derived by the at least one pressure sensor and comprises an electronic storage device which is attached to or in the shoe body. The method according to the invention carried out in connection with such a sports shoe comprises the method steps:

[0024] - Determination or generation of shoe and / or user-specific calibration data relating to the at least one pressure sensor;

[0025] - depositing at least the shoe and / or user-specific calibration data in the electronic storage device;

- Reading out the calibration data from the storage device by means of an electronic signal processing device which can be put into functional interaction with the sports shoe or is in functional interaction;

- Processing or application, such as linking, from the memory

4.24

AT 521 347 B1 2020-01-15 Austrian patent office direction read calibration data in connection with pressure signals, which are generated or provided by the at least one pressure sensor.

According to the invention, it is further provided that shoe and foot specific calibration data relating to the left foot and the left sports shoe of a user are stored in the electronic storage device of the sports shoe to be worn on the left, and that shoe and foot specific calibration data relating to the a user's right foot and right athletic shoe are stored in the electronic storage device of the athletic shoe to be worn on the right. This enables a high quality of the evaluation results or the generated usage information to be achieved. The individual and specific data assignment to the left or right sports shoe of a pair of sports shoes to be used in combination, however, also simplifies the control-technical requirements, or logistical requirements can thereby be advantageously standardized.

The measures according to the invention can ensure high-quality data and signal acquisitions. In particular, this makes it possible to differentiate noise signals or signal components that are not particularly useful from a technical point of view from useful signals. In addition, electrical pressure levels can thereby be provided by the pressure sensors, which guarantee the highest possible signal bandwidth or can supply easily usable signaling information. In addition, this can increase economic efficiency in terms of the structure and use of an electronic evaluation or Control system can be achieved. However, the functional availability and robustness of such an electronic system can also be improved by the specified measures. Further advantageous effects and technical effects can be found in the preceding and the following parts of the description.

[0030] In order to determine or generate the shoe and / or user-specific calibration data as quickly as possible and at the same time fail-safe, an initialization process can be provided, which initialization process comprises the following method steps:

- loading the at least one pressure sensor with a nominal or reference pressure or establishing a stress-free idle state of the sports shoe;

[0032] - Detection of the pressure signals of the at least one pressure sensor that arise or are provided;

[0033] - Comparing the pressure signals of the at least one pressure sensor with a setpoint value series or a defined reference or target value;

- Setting or calculating the calibration data as a function of the determined deviation of the pressure signals of the at least one pressure sensor from the setpoint value series or the defined reference or target value.

It may be expedient if the calibration data stored in the storage device are read out from the storage device by the signal processing device via at least one electrical line and / or at least one interface with contacts. As a result, an energy-saving and at the same time reliable signal or data transmission can be established between the said components or electronic units, and simple and intuitively executable handling for establishing a data link can also be guaranteed.

A particularly high level of user comfort or an almost fully automatic initialization and / or technical coupling can be achieved if the calibration data stored in the storage device from the signal processing device by means of wireless data transmission, in particular via a near-field data communication link (RFID / NFC link) from the storage device be read out.

Optimized signal recordings and data surveys which represent the actual load conditions of the sports shoe as well as possible can be achieved if the calibration data for signal or data balancing or weakening of swan

AT 521 347 B1 2020-01-15 Austrian patent office, which influences fluctuations on batch-specific fluctuations of the at least one pressure sensor, on manufacturing tolerances of the athletic shoe, on production or age-related fluctuations in athletic shoe stiffness, and / or on user-specific, individually different pressure loads based at least one pressure sensor.

Furthermore, it may be expedient if the electronic signal processing device is designed to carry out an assignment process after each restart or after each activation, and / or after each charging process of its energy store, and / or based on a predefined, manually triggerable operating action, in which assignment process an attempt is made to read in the calibration data from the storage device arranged on a sports shoe. As a result, faulty signal evaluations and consequently incorrect recordings of pressure conditions can be prevented. In addition, this facilitates the portability of an electronic signal processing device or enables a delayed usability by a plurality of users.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures. Each show in a highly simplified, schematic representation:

[0040] FIG. 1 shows an embodiment of a sports shoe designed as an alpine ski shoe in a side view;

Fig. 2 is a removable inner shoe for an alpine ski boot as needed with an outer shell, which is made of comparatively hard plastic;

[0042] FIG. 3 shows an electrical plug interface of a sports shoe, in particular an inner shoe, with an electronic storage element;

4 shows a further electrical connector interface of a sports shoe with a wirelessly readable, electronic storage element;

5 shows a user with a pair of sports shoes designed according to the invention in combination with an electronic control or evaluation system.

In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, the disclosures contained in the entire description being able to be applied analogously to the same parts with the same reference numerals or the same component designations. The location information selected in the description, e.g. above, below, to the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.

1 shows a side view of an exemplary sports shoe 1, which is designed here as a ski shoe.

Instead of the ski boot shown as an example, the corresponding sports shoe 1 can also be formed by a cross-country ski boot, a snowboard boot or the like. In particular, a generic sports shoe 1 is to be understood as any shoe which comprises an outer, comparatively stiff shell 2 or at least a relatively stiff cuff or shaft section and a comparatively soft and resilient inner shoe 3 inserted therein and is provided for the practice of skiing ,

The ski boot shown consists essentially of an outer, relatively dimensionally stable shell 2 and a comparatively flexible inner shoe 3. The inner shoe 3 is preferably made of foam plastic and textile materials in order to offer the user the greatest possible comfort when the user's foot is accommodated in the sports shoe 1, in particular in the inner shoe 3. The inner shoe 3 can preferably be made removable or replaceable compared to the shell 2, as shown in FIG. 2, or

6.24

AT 521 347 B1 2020-01-15 Austrian patent office but permanently connected to the shell 2, in particular glued or sewn. According to a possible embodiment, the sports shoe 1 can be designed as a touring ski boot, in which case the inner boot 3 can also be designed with a laces. According to a particularly expedient embodiment, the sports shoe 1 is designed as an alpine ski shoe, the inner shoe 3 usually not having its own closing or fastening means here.

The outer shell 2, for example manufactured by means of a plastic injection molding process, can also have a plurality of openings and thus also a frame or. Form cage-like holding structure for the inner shoe 3. The outer shell 2 around the inner boot 3 serves to transfer forces between the foot of the user and the respective sports equipment on which the ski boot is attached or arranged as efficiently as possible or without delay.

In both variants of a ski boot, be it as an alpine ski boot or a touring ski boot, the inner boot 3 is accommodated in the shell 2 and a foot accommodated by the inner boot 3 can be held in the inner boot 3 by reducing the volume of the shell 2. The volume of the shell 2 is reduced by at least one tensioning device 4, typically tensioning buckles, wherein a different number of tensioning devices 4 can be arranged on the shell 2 on a ski boot, depending on the design model.

The shell 2 preferably comprises a forefoot shell 7 for receiving the foot of a user and a cuff 6 adjoining the forefoot shell 7, which at least in sections surrounds or receives the lower leg section of a user. The cuff 6 - also known as a shoe upper - is preferably designed as a structurally independent element and is connected to the forefoot shell 7 via two pivot bearing devices 5. The pivot bearing devices 5 positioned on opposite side surfaces of the sports shoe 1 thus form an articulated connection between the cuff 6 and the forefoot shell 7, which enables angling between the forefoot shell 7 and the cuff 6. Of course, this articulated connection can also comprise connecting means which enable a combined translatory and rotary coupling.

As shown in Fig. 1, two clamping devices 4 can be arranged on the forefoot shell 7 and on the cuff 6, respectively. However, versions with a total of two or three tensioning devices 4 per sports shoe 1 are also possible. A band-shaped tensioning means 8 can also be arranged on the cuff 6 of the sports shoe 1, by means of which a foot accommodated in the sports shoe 1, in particular the lower leg section of a user, can be additionally stabilized. The band-shaped tensioning means 8 for the cuff 6, as can be seen from FIG. 1 by way of example, preferably extends continuously, in particular ring-like, over the circumference of the upper end portion of the sports shoe 1.

A sports shoe 1 designed according to the invention comprises at least one pressure sensor 9a-d for the electrotechnical or electronic detection of mechanical pressures or forces in or on the sports shoe 1. In particular, at least one pressure sensor 9a-d is provided in or on the sports shoe 1, which has mechanical loads , in particular pressures or forces between the foot of the user and the sports shoe 1, can be converted into corresponding electrical signals or can provide corresponding signals. The at least one electronic pressure sensor 9a-d can be designed as an active or a passive pressure or force sensor. The at least one sensor 9a-d is expediently designed as a pressure-sensitive resistance element or as a detector operating according to the resistive or ohmic principle of action. Different pressure loads which act on the pressure sensor 9a-d are represented as different electrical resistance values, which can then be distinguished or detected from one another by electrical signals. According to an advantageous embodiment, at least one of the pressure-sensitive sensors 9a-d of the sports shoe 1, in particular on the inner shoe 3 thereof, is formed by a textile pressure sensor, which has a relatively high degree of shape flexibility or adaptability in relation to the three-dimensional shape of an inner shoe 3 or in relation to it on the contours

7.24

AT 521 347 B1 2020-01-15 Austrian patent office allows a foot shape. Such pressure sensors 9a-d are also known as “textile sensors” and are well suited for attachment to or for integration into soft-elastic or textile objects, in particular in relation to the inner shoe 3 of the generic sports shoe 1. However, it is also possible to form at least one of the pressure sensors 9a-d by a pressure sensor operating according to the piezoelectric principle of action.

2 illustrates electrotechnically evaluable pressure sensors 9a-d at appropriate positions of an inner shoe 3.

According to a practical embodiment, at least one pressure sensor 9a can be positioned in the front sole section of the inner shoe 3, which front sole section is assigned to the toe pads or the forefoot section of a user in the use or use state of the sports shoe 1.

[0056] In addition, at least one pressure-sensitive sensor 9b can be positioned in the rear sole section of the inner shoe 3, which is closest to the heel bone of a user.

Combined evaluation of the pressure signals, based on or provided by the pressure sensors 9a and 9b, makes it possible, in particular, to draw conclusions regarding the weight distribution or the so-called balance of the user in terms of sensors. The sensor-related recording of the weight distribution of the user in relation to the forefoot and / or heel bone is of particular importance and practicality in connection with ski boots for the practice of alpine skiing, since the respective weight distribution or the dynamic weight shift of the user can be detected.

According to a further alternative or combinatorial embodiment, at least one pressure sensor 9c can be provided in or on the inner shoe 3, which absorbs the compressive forces or loads acting on the lower leg or shin section of a user. Appropriately, this pressure sensor 9c, as schematically shown in FIG. 1, is positioned in a section of the sports shoe 1 which is closest to the front section of the cuff 6. According to the example, the at least one sensor 9c is formed directly in or on the tongue 10 of the inner shoe 3, as was illustrated by the broken lines in FIG. 2. As a result, the so-called template or the shift in the center of gravity of a user can be practically detected in the forward direction.

According to an expedient measure, provision can also be made to provide at least one pressure-sensitive sensor 9d in the rear section of the upper of the inner shoe 3, as was indicated in FIGS. 1, 2 with dash-dotted lines. The rear section of the inner shoe upper is essentially assigned or assignable to be closest to the fibula of a user. As a result, so-called reserves or shifts in the center of gravity of a user in the rearward direction can be appropriately recorded.

2 represents configurations of the pressure sensors 9a-d in the inner structure of the inner shoe 3. In particular, the pressure sensors 9a-d are at least partially embedded in the material, in particular in the plastic material of the inner shoe 3. Alternatively, it is of course also possible to provide at least one of the sensors 9a-d on the outer surface of the inner shoe 3 or on the inside of the inner shoe 3 closest to the foot of a user, in order to be in relatively direct contact with the foot or the sock one To stand users of the sports shoe 1.

The respective pressure forces between the foot of the user and the athletic shoe 1 or between the athletic shoe 1 and the ground, for example a sports device coupled to the athletic shoe 1, can thus be recorded electronically or sensor technology via the at least one pressure sensor 9a-d evaluated or monitored by means of evaluation electronics described below.

To optimize this data-technical evaluation or evaluation

8.24

AT 521 347 B1 2020-01-15 Austrian patent office, it is useful if the sports shoe 1 has at least one radio communication interface 11. This radio-technical communication interface is provided for the wireless transmission of pressure signals or pressure-related data, which were recorded via the at least one pressure sensor 9a-d. The radio communication interface 11 is provided for a signal or data transmission in the close range, that is, for a maximum transmission distance of up to 100 m, preferably of up to 3 m. It is expedient if the radio communication interface 11 of the sports shoe 1 is designed for signal or data transmission according to the Bluetooth, ZigBee, NFC or WLAN standard. RFID communication systems are also conceivable in this context. It is essential that this radio-technical communication interface 11 of the sports shoe 1 is compatible with a standardized, radio-technical communication interface 12 on at least one standardized, electronic evaluation device 13. In particular, the communication interface 11 on the sports shoe 1 is designed for data communication with a corresponding communication interface on an external, preferably mobile, electronic evaluation device 13. The signal or data transmission can take place unidirectionally starting from the communication interface 11 in the direction of the communication interface 12 of the evaluation device 13. However, bidirectional data communication is preferably provided between the shoe-side communication interface 11 and the external, evaluation-side communication interface 12, as was indicated in FIG. 1 by means of a double arrow. The electronic evaluation device 13 serves at least to evaluate the pressure conditions detected by the at least one pressure sensor 9a-d or the electrical pressure signals derived therefrom. In particular, the electrical pressure signals of the at least one sensor 9a-d are transmitted in data technology form to the electronic evaluation device 13 via the shoe-side communication interface 11 and are processed or evaluated by means of the latter and signaled, in particular at least visualized, in a form which is practical for a user of the evaluation device 13.

The electronic, preferably mobile evaluation device 13 is preferably formed by a commercially available, mobile computing unit 14, in particular defined by a smartphone 15, as was illustrated in FIG. 5. Alternatively or in combination with a smartphone 15, it is also possible to use a standard tablet PC or a so-called wearable computer, for example in the form of a wristwatch. The radio communication interface 12 of these aforementioned electronic units, which is present as standard, is compatible with the radio communication interface 11 implemented on the sports shoe 1. In particular, the radio communication interface 11 on the sports shoe 1 is designed such that it can establish a data communication connection with at least one radio communication interface 12 of the aforementioned mobile computing units 14, in particular with a radio communication interface 12 of a smartphone 15. The mobile computing unit 14, in particular the smartphone 15 of the user - FIG. 5 - has a data link with the communication interfaces 11 in each case on each of the two sports shoes 1 of the user. This means that a data connection between the mobile computing unit 14, in particular the smartphone 15, of the user and the two sports shoes 1 worn by this user is established or can be established. Thus, a two-channel, radio connection between the pair of sports shoes 1 of the user and his smartphone 15 can be provided.

It may be expedient if the radio communication interface 11 on the respective sports shoe 1 is defined by a Bluetooth communication interface, which with the corresponding, standardly implemented Bluetooth communication interface 12 of a commercially available, mobile computing unit 14, in particular on a smartphone 15, on a tablet PC, or on a wearable computer, for example in the manner of a wristwatch.

As can best be seen from FIGS. 1 and 2, the is at least one pressure sensor

9a-d of the sports shoe 1 can be connected or connected to an electronic signal processing device 16, in particular line-connected. This electronic signal processing device 16 is preferably arranged or positionable on the sports shoe 1 and is used, among other things, for conditioning or conditioning the electrical pressure signals provided by the at least one pressure sensor 9ad. The pressure sensors 9a-d are each connected via electrical cable connections 17a-d to a microcontroller 18 or a comparable electronic evaluation circuit within the signal processing device 16. Preferably, the pressure sensors 9a-d are optionally electrically connectable and disconnectable via cable connections 17a-d and via at least one plug-in interface 23 with the signal processing device 16 or with its microcontroller 18.

It is also conceivable to assign at least one temperature and / or humidity sensor 19 - FIG. 1 - to the signal processing device 16, which electrical signals corresponding to the prevailing temperature and / or humidity conditions via at least one line to the microcontroller 18 for processing or evaluation transfers. As shown schematically in FIG. 1, such a temperature and / or moisture sensor 19 can preferably be positioned in the toe or midfoot section of the sports shoe 1. The signal processing device 16 is then provided for the wireless transmission of the respective temperature and / or moisture data to the mobile computing unit 14, in particular to the smartphone 15, by means of which the visualization, monitoring and / or logging of the respectively present temperature and / or moisture values in the sports shoe 1 can be made.

The pressure sensors 9a-d can be designed as pressure / voltage converters, while an optional temperature and / or humidity sensor 19 can also be understood as a corresponding converter or as a converter circuit.

The electronic signal processing device 16 on the sports shoe 1 of a user is further coupled in terms of signal technology to the radio communication interface 11 already explained above, or the electronic signal processing device 16 comprises this radio communication interface 11. According to a typical embodiment, as illustrated in FIG. 1, the microcontroller 18 is connected to the typically modular radio communication interface 11 via at least one data or signal line 20. In order to supply the electronic signal processing device 16 with electrical energy, in particular to supply the various pressure sensors 9a-d and the microcontroller 18, at least one electrical energy supply source 21, in particular at least one battery or an electrochemical accumulator, is also formed on or in the signal processing device 16.

The signal processing device 16 further comprises at least one electronic data memory for system-relevant data or operating states. As an alternative or in combination, such data can be stored on the user, in particular by means of the user's mobile computing unit 14, for example in his smartphone 15, and / or in a storage device (cloud storage) accessible via a data network.

The electronic or electrotechnical components of the signal processing device 16 are preferably housed in a housing 22. In contrast, in particular the pressure sensors 9a-d are positioned externally with respect to the housing 22 and either directly, but preferably via a one that can be activated and deactivated as required, via the electrical lines or cable connections 17a-d already mentioned - see FIG Plug interface 23, with the electronic signal processing device 16 line-connected or connectable. According to an expedient embodiment, the housing 22 of the electronic signal processing device 16 is arranged or positionable in the cuff area of the sports shoe 1, in particular on the rear side of the cuff 6, as is exemplarily illustrated in FIG. 1. In this case, a holding device 24, for example a mounting bracket 25, can be provided, via which the housing 22 in the vicinity

10/24

AT 521 347 B1 2020-01-15 Austrian patent office of the upper collar section of the cuff 6 can be detachably attached if necessary. The electronic signal processing device 16, in particular its housing 22, is preferably detachably mounted or mounted on or in the sports shoe 1, if necessary. As a result, practical charging or regeneration of the energy supply source 21 and simple maintenance of the electronic signal processing device 16 can be carried out, among other things. The shoe-side electronic signal processing device 16 or communication interface 11 and the peripheral or externally arranged electronic evaluation device 13 or the corresponding mobile computing unit 14 form an electronic evaluation or control system 26 - FIGS. 1 and 5 - for the user of the sports shoe 1 out. The corresponding control system 26 also provides a helpful tool for sales or service companies of such sports shoes 1, in particular for sporting goods dealers, to increase customer satisfaction.

According to a practical embodiment, a sports shoe 1, in particular a ski shoe, is thus provided, which sports shoe 1 comprises a lower shoe section 27 for receiving the foot of a user and an upper shoe section 28 provided for receiving the lower leg section of this user. The upper shoe section 28 is connected to the lower shoe section 27, for example articulated, as illustrated in FIG. 1. A generic sports shoe 1 is thus designed like a boot or extends well beyond the ankles of a user.

As previously explained, the sports shoe 1 comprises a sensor arrangement 29 which comprises a plurality of pressure sensors 9a-d arranged in a distributed manner. The pressure sensors 9a-d are each connected or connectable to the electronic signal processing device 16, which is preferably arranged or can be arranged directly on the sports shoe 1 or on the leg of the user, via at least one-pole, in part via two-pole cable connections 17a-d.

At least two pressure sensors 9a, 9b of the sensor arrangement 29 are provided in or on a sole arrangement 30 of the sports shoe 1 which is closest to the sole of the foot of a user. At least one first pressure sensor 9a is positioned in a forefoot section 31 of the sole arrangement 30 of the sports shoe 1 and at least one second pressure sensor 9b is positioned in a heel section 32 of the sole arrangement 30. With respect to a longitudinal axis 33 of the sole, the forefoot section 31 can take up about a third of the sole length, while the heel section 32 can also take up about a third of the sole length.

It may be expedient if a single first pressure sensor 9a is provided, which is arranged at least predominantly or entirely eccentrically to the longitudinal axis 33 of the sole, in particular is positioned closer to the inside of the sports shoe 1, as can be seen in FIG. 2 , As a result, relatively clear force measurements or pressure recordings can be carried out and meaningful conclusions can be drawn in a relatively efficient manner about the upward-edging or guiding behavior of the user in relation to skis to be used in pairs.

Furthermore, it may be expedient to provide in the heel section 32 of the sole arrangement 30 only a single second pressure sensor 9b, which is positioned as centrally as possible with respect to the longitudinal axis 33 of the sole, as is indicated schematically in FIG. 2. As a result, relatively good acquisition and evaluation results can be achieved despite the lowest possible set-up or hardware costs.

The single sensors 9a-d are electrically conductively connected or connectable to the signal processing device 16 via single or multi-pole cable connections 17a-d. This electrical connection is either permanently provided or, if necessary, can be produced and releasably implemented.

As can best be seen from FIG. 2, in a tongue section 35 closest to the shin of a user, the tongue 10 of the sports shoe 1 can be at least / 24

AT 521 347 B1 2020-01-15 Austrian patent office a third pressure sensor 9c can be arranged. This pressure sensor 9c is connected or connectable to the signal processing device 16 via a third cable connection 17c. The third cable connection 17c between the third pressure sensor 9c and the signal processing device 16 runs from the third pressure sensor 9c over the tongue section 35, the instep section 36, the toe section 37, the sole arrangement 30 and over the heel area of the sports shoe 1 towards the rear of the upper shoe section 28, in which the signal processing device 16 is preferably arranged or can be arranged.

According to a practicable embodiment, the at least one first pressure sensor 17a and the at least one second pressure sensor 17b are designed as area-limited, in particular as circular thin-film resistance sensors which are glued or sewn onto the underside of the sole layer of the sole arrangement 30.

It is also practical if at least a fourth pressure sensor 9d is arranged in a calf section 38 of the sports shoe 1 which is closest to the calf of a user and which is connected or connectable to the signal processing device 16 via a fourth cable connection 17d, as shown in FIG. 2 has been illustrated.

According to a practical embodiment, it can be provided that the cable connections 17a-d in the upper shoe section 28 merge into a common, first connector interface 23. This first plug interface 23, which can be designed in particular as a socket 39, can be electrically coupled to a corresponding second plug interface 40, in particular a plug element 41. The second plug interface 40 can be formed directly on the signal processing device 16, in particular on its housing 22, or can be routed to the signal processing device 16 via a fifth cable connection 42. It is also practical if the fourth cable connection 17d, starting from the fourth sensor 9d, which is positioned in the calf section 38, is led directly to the first plug interface 23, as can best be seen from FIG. 2.

In contrast, it is practical if the first, second and third cable connections 17a-c are led vertically upwards from the heel section 32, over the Achilles tendon section of the sports shoe 1 to the first connector interface 23, as best shown in FIG. 2 can be seen.

According to a preferred embodiment, the first plug interface 23 is positioned in the upper end or collar section of the upper shoe section 28, in particular in the area of the cuff of the sports shoe 1, as was schematically illustrated in FIGS. 1 and 2.

The cable connections 17a-d can be formed by electrical cables or individual lines. Alternatively or in combination, it is also possible to design at least partial sections of at least one of the cable connections 17a-d as multi-pole foil conductor tracks, in particular by means of conductor tracks printed on plastic foils. This offers the advantage of relatively thin cable connections 17a-d that can be implemented particularly without pressure points in the relatively soft construction of the inner liner 3.

As can be seen from FIG. 2 by way of example, an electronic storage device 43 is attached to or in the shoe body and is provided for storing at least one shoe and / or user-specific calibration data relating to the at least one pressure sensor 9a-d. The shell 2 and / or the inner shoe 3 of the sports shoe 1 are to be understood as the shoe body. According to an advantageous embodiment, this storage device 43 is assigned to the first plug interface 23 in the closest manner, in particular arranged within its socket 39 or assigned to the housing of the socket 39.

The electronic storage device 43 can be formed by an EEPROM chip in a miniature housing, which is preferably permanently connected to the sports shoe 1, in particular can be integrated into the electrical connector interface 23 of the sports shoe 1. According to a practical embodiment, signal processing can be carried out

12/24

AT 521 347 B1 2020-01-15 Austrian patent office direction 16 for writing to the storage device 23 with the shoe and / or user-specific adjustment or calibration data. In particular, it can be provided that after a preferably manual activation or initiation of a calibration process or initialization process, the signal processing device 16 stores the corresponding calibration data in a non-volatile manner in the electronic storage device 43.

The calibration data can in particular be formed by correction factors or compensation parameters. These correction factors or compensation parameters are provided for signal or data-technical compensation or attenuation of fluctuation influences, which fluctuation influences on batch-specific fluctuations of the at least one pressure sensor 9a-d, and / or on manufacturing tolerances of the sports shoe 1, and / or on production or age-related fluctuations in the stiffness of the sports shoe , and / or based on user-specific, individually different pressure loads compared to the at least one pressure sensor 9a-d. In particular, this takes into account the technical problem that, among other things, the individual foot shapes and / or the different body weights of users already exert different pressure loads compared to the at least one pressure sensor 9a-d in a rest or initial state. Furthermore, batch-specific or production-specific tolerances of the pressure sensors 9a-d and / or of the sports shoe 1 or age-related fluctuations in the named components can be at least partially compensated for or effectively compensated for by the corresponding calibration data. Ultimately, the meaningfulness or the information content and / or the signal level in relation to that detected by the at least pressure sensor 9a-d is improved by the calibration data recorded individually for each user and / or by the specific sports shoe 1 and subsequently stored in the electronic storage device 43 Optimized signals.

The calibration data preferably determined individually for each user of the sports shoe 1 and subsequently stored in the storage device 43 of this sports shoe 1 are subsequently provided for reading out and processing by means of an electronic signal processing device 16 which is capable of functional interaction with the sports shoe 1 or which is in functional interaction ,

An advantageous sequence comprises at least the measures described below: The shoe and / or user-specific calibration data relating to the at least one pressure sensor 9a-d are determined or generated. For this purpose it can be provided that the user of the sports shoe 1 assumes a defined basic posture or basic position and / or executes a defined sequence of movements and in this basic position or during the execution of the sequence of movements automatically detects and signals the respective signals from the at least one pressure sensor 9a-d to be analyzed. This can be done under professional guidance from a sporting goods retailer and / or can be done independently by the user, preferably by interacting with his smartphone 15 - FIG. 5 - and / or using instructions via his smartphone 15, in particular by means of a so-called “wizard” in Form of a calibration or installation assistant are supported. The correspondingly recorded or calculated calibration data are then stored permanently or non-volatilely in the storage device 43 arranged on the shoe side. This deposit is preferably made via the electronic signal processing device 16. Alternatively, it is also conceivable to provide an independent calibration device which is designed at least for the determination and / or storage of the respective calibration data on the shoe side.

After completion of this initialization process or calibration process, the individually or specifically determined compensation or calibration data are stored in the storage device 43. This calibration process or initialization process can include the following method steps: the at least one pressure sensor 9a-d is loaded with a nominal or reference pressure or a stress-free idle state of the sports shoe 1 is established. The resulting or provided pressure signals of the at least one pressure sensor 9a-d are recorded or evaluated. The pressure signals of the at least one pressure sensor 9a-d are compared with a setpoint value series or a defined target value. This target or

13/24

AT 521 347 B1 2020-01-15 Austrian patent office

Target values correspond to a so-called calibration standard. The respective calibration data are determined or calculated as a function of the determined deviation of the pressure signals or data of the at least one pressure sensor 9a-d from the setpoint value series or the defined target value.

The calibration data can then be read out of the shoe-side storage device 43 at any time by means of an electronic signal processing device 16 which can be brought into functional interaction with the sports shoe 1 or which is in a functional interaction. This calibration data should be read out at least once in advance of an evaluation of the pressure conditions in the sports shoe desired by the user

1. In particular, if the load or pressure conditions are to be monitored as precisely as possible in the course of the intended use or exercise with the sports shoe 1, it is expedient to read out the user-specific or shoe-specific calibration data in the storage device 43 at least once or initially and subsequently to process or flow into the evaluation routines of the evaluation device 13. In particular, it is expedient if the calibration data read out from the storage device 43 is processed or used in relation to the pressure signals or pressure data which are generated or provided by the at least one pressure sensor 9a-9d. This means that at least in the signal processing device 16 and / or in the evaluation device 13 the compensation or calibration data is linked to the pressure signals provided or generated by the pressure sensors 9a-d. As a result, the respective detection or evaluation result can be improved and the meaningfulness of the electronic monitoring of the pressure profiles during certain phases of use of the sports shoe 1 can be optimized.

The initialization process can also be understood as a process in which the respective sports shoe 1 and the foot of a user are compared to one another or brought into relation to one another, the respective calibration data being ascertained in the course of this.

The electronic signal processing device 16 can be designed to one after each restart or after each activation, after each charging process from its energy store or energy supply source 21 - FIG. 1, or based on a predefined, manually executable or triggerable operating action Execution of the assignment process, in which assignment process an attempt is made to read in the respective calibration data from the storage device 43 arranged on a sports shoe 1. The corresponding read-in or refreshing processes can be determined or initiated by software-stored processes within the signal processing device 16 and / or the evaluation device 13 - FIG. 1.5.

3 shows an embodiment of a connector interface 23 formed on the sports shoe 1. This plug interface 23 is part of a film or textile-like carrier layer 44, on which at least some of the lines 17a-d can be printed or vapor-deposited. Contact tongues 45 at the free end of the carrier layer 44 form contact-based interfaces to a signal processing device 16 (FIG. 1) that can be connected and disconnected as required. The film-like carrier layer 44 is of flexible design and is attached to the sports shoe 1, in particular to the inner shoe 3, at least in sections.

The electronic storage device 43 for storing the used and / or shoe-specific calibration data can be arranged directly on the carrier layer 44. In particular, connections of the electronic storage device 43 can be soldered to at least some of the lines 17a-d and / or glued to the carrier layer 44 in an electrically conductive manner. The calibration data stored in the storage device 43 can be read out from the storage device 43 and / or by the signal processing device 16 - FIG. 1 - via at least one electrical write / read line 46 and / or at least one contact-related write and / or read interface 47 are written into the electronic storage device 43.

14/24

AT 521 347 B1 2020-01-15 Austrian Patent Office [0095] In addition to storing the shoe and / or user-specific or foot-specific calibration data in the shoe-side storage device 43, provision can also be made for this calibration data to be stored in a fixed, in particular in a remotely accessible, storage device ( not shown). This quasi-external storage device with remote data access can be formed by a specific data server protected from unauthorized access or by a cloud data storage service protected from unauthorized access. In the event of any problems in connection with the reading out of the data from the shoe-side storage device 43, this makes it possible to call up the respective calibration data virtually externally via remote data access. A renewed initialization or calibration process to determine the respective shoe and / or user-specific calibration data, which process means a certain amount of time and technical investigation effort, can thus be dispensed with.

4 shows a further exemplary embodiment of a shoe-side connector interface 23 between at least some of the pressure sensors 9a-d and a signal processing device 16, FIG. 1, which can be connected and disconnected as required. Here, the plug interface 23 is formed as a plug element 48 with a plurality of electrical contact tongues 45. The free end section of the plug element 48 or its cable to the pressure sensors 9a-d - FIGS. 1, 2 protrudes from the outside of the sports shoe 1 and can be guided through an opening 49 in the outer shell 2.

The electronic storage device 43 is a component of a passive RFID transponder unit 50. The storage device 43 with the calibration data or a corresponding identifier is read out by means of a wireless data transmission interface 51, in particular via a near field data communication link (NFC). This reading is preferably carried out via the battery-powered signal processing device 16 that can be attached in the immediate vicinity or attached to the sports shoe 1. As is known per se, the RFID transponder unit 50 is battery-free and can be electrically activated by the signal processing device 16 via a corresponding reading interface and detected without contact ,

The RFID transponder unit 50, which comprises the electronic storage device 43 for the user- and / or shoe-specific adjustment or calibration data or for a representative identification (code) in this regard, and in particular contains a unique identification feature, can - as shown schematically - be arranged directly on or at the plug interface 23. However, the RFID transponder unit 50 including the memory device 43, which can be detected in a contactless or contactless manner, can also be integrated into the plug interface 23, in particular built into it. As an alternative to this, it is also possible to fix the RFID transponder unit 50 coupled to the storage device 43 or the 43 RFID transponder unit 50 containing the storage device 43 in a non-detachable manner, in particular to embed it in or stick to it.

According to a further exemplary embodiment, as illustrated with dashed lines in FIG. 4, the relevant RFID transponder unit 50 can also be designed in the manner of an NFC tag or adhesive label and directly on the shell 2 or on the inner shoe 3 the sports shoe 1 glued or held in a pocket-like receptacle.

The exemplary embodiments show possible design variants, it being noted at this point that the invention is not restricted to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action The present invention resides in the ability of the person skilled in the art in this technical field.

The scope of protection is determined by the claims. However, the description and drawings are to be used to interpret the claims. Individual features or combinations of features from the different embodiments shown and described
