Description

TECHNICAL FIELD AND OBJECT OF THE INVENTION The present invention relates to the field of geolocation and relates more particularly to a device and a geolocation system integrable in a shoe. STATE OF THE ART In order to locate people geographically, it is known to use a portable geolocation device, also called tracer type box, integrated in a shoe.

Such a device comprises in known manner a location module, a communication module and a battery configured to power said modules. The locating module comprises an antenna for receiving a plurality of signals, received from a first satellite navigation network (Global Navigation Satellite System (GNSS)). Such a GNSS network comprises a plurality of satellites that each transmit signals to the Earth. The location module determines the geographical position of the device in a known manner, by trilateration, from signals transmitted to the Earth by satellites covering the terrestrial area in which the device is located (generally four satellites).

The communication module is configured to transmit through a second telecommunications network, via a transmitting antenna, a signal comprising the geographical position of the device determined by the location module. Typically, the second network is a Global System type network for Mobile Communication (GSM).

Such a GSM network comprises a plurality of antennas each covering different terrestrial areas. Each antenna transmits or receives signals from terminals within its coverage area so that they can communicate via the GSM network. The geographical position of the device is communicated through the second network to a terminal or a server, for example so as to be made available to a user who wishes to know the position of the person wearing the shoe comprising the geolocation device. Thus, patent application US2011 / 0260857 A1 discloses a geolocation device integrated in a shoe sole and comprising a positioning module of the Global Positioning System (GPS) type comprising an antenna for receiving a plurality of first signals, a communication module comprising a transmitting antenna of a second signal comprising the geographical position of the device determined by the location module and a battery.

The electronic components used in this device are however numerous, bulky, heavy, fragile and relatively rigid, which makes the shoe uncomfortable and presents a significant risk of deterioration for the device.

In addition, the position of the receiving antenna in the middle of the shoe is not optimal. In particular, such positioning leads to the use of an amplifier consuming a large amount of battery power, which significantly reduces the autonomy of the device. In addition, such positioning of the antenna degrades the quality of the first signals received, or even prevents the reception, which makes the device very imprecise or unusable. In addition, such positioning of the antenna stiffens the sole and subjects the antenna to the weight of the user so that it can be weakened or even inoperative. Similarly, the electrical circuit described in this solution covers a large area of the sole, does not make the device both flexible enough, solid and compact, especially in the context of running. Finally, such a geolocation device can not send the geographical position information of the device in the case where the receiving antenna is not in the coverage of the first telecommunications network or in the case where the antenna of issue is not in the coverage of the second telecommunications network.

GENERAL PRESENTATION OF THE INVENTION The object of the present invention is to remedy at least in part these drawbacks by proposing a shoe sole comprising a geolocation device that is at the same time simple, light, reliable, solid, flexible, compact and not very consuming. energy. For this purpose, the subject of the invention is a shoe sole comprising a geolocation device, said device being remarkable in that it comprises: a control module, preferably a single module, configured to determine the geographical position of the device to be from at least a first signal, preferably a plurality of first signals, received from a first telecommunications network and for transmitting, through a second telecommunications network, a second signal comprising said geographical position of the device, - a module power supply configured to supply power to said control module, and - a single transmission antenna configured to receive the first signal from the first telecommunications network and to transmit the second signal through the second telecommunications network.

The transmission of the second signal can be done, for example, to a server or a terminal connected to said second network. Such a so-called "hybrid" antenna, used both for receiving the first signal and for transmitting the second signal, ensures optimum operation between the reception and the transmission of the signals, which notably makes it possible to avoid interference. caused on the control module by a plurality of separate antennas. In addition, the positioning of the transmission antenna in the immediate vicinity of the control module also allows it to be connected directly to said module and thus to avoid the use of an energy-consuming amplifier. Such an antenna is also very easy to integrate into a shoe sole. For example, the antenna can advantageously be mounted on or in the rear edge of the sole. Such positioning allows the device to be mounted in any type of sole, including multi-size soles whose front portion is cut. In addition, such positioning of the antenna does not hinder the support of the user and does not subject the antenna to the weight thereof. Finally, such positioning of the antenna makes it possible to improve the transmission and reception of the signals. When the first network emits circular waves, for example a satellite positioning network of the GPS network type, the hybrid antenna may advantageously have substantially the shape of a semicircle in order to significantly improve the reception of the GPS signal. Preferably, the arc length of the semicircle is of the order of X / 2 where λ is the wavelength of the first signal. In addition, such an arc length is advantageous since it can significantly reduce the interactions between the signals emitted by the antenna and the wearer's body of the sole of the shoe comprising the device. In particular, when the second network is a GSM-type network, such an arc length makes it possible to comply with the existing GSM security standards for transmitting signals for the human being. More preferably, the transmission antenna is a multifrequency transmission antenna configured, for example, to receive the first signal in the frequency band [1 575.42 MHz - 1 227.60 MHz] and to transmit the second signal. in the GSM 850-1900 and / or GSM 900-1800 frequency bands. According to one aspect of the invention, the hybrid antenna is printed from nano components. This makes it both ultra-flat, flexible, easily integrated into a shoe sole and resistant to shocks, humidity and temperature variations. This also makes it possible to significantly improve the comfort of the shoe sole 30 while keeping it supple. According to another aspect of the invention, the control module is configured to select the first network in a first plurality of telecommunications networks and to select the second network in a second plurality of telecommunications networks. The control module can thus use different first networks and different second networks depending on their availability or the power of the signals they emit.

The selection of the first network can be done from a first criterion, for example the power of the first signal received. Similarly, the selection of the second network can be made from a second criterion, for example, the power of the signal transmitted by one or more antennas of the second network. Advantageously, the control module may comprise a switch (in English language) configured to select the first network and the second network from one or more selection criteria (coverage, power of the received signals, etc.). ). Such a control module makes it possible to determine the geographical position of the device even when the signals of one of the networks previously used to make this determination are no longer received by the device. The control module selects in this case another available network in the plurality of first networks. Similarly, the control module makes it possible to send the geographical position of the device even when a second network previously used to make this sending is no longer available.

According to a characteristic of the invention, the control module comprises a memory zone making it possible to store control data of the device or data relating to the geographical position of the device. Advantageously, the control module and the transmission antenna are connected by a first flexible or rigid electrical link such as, for example, a rigid connector. Such a rigid connector makes it possible to reduce the signal losses between the control module and the antenna.

Advantageously, the control module and the power supply module are connected by a second electrical link, preferably flexible.

According to one characteristic of the invention, the power supply module is configured to supply the transmission antenna either directly or through the control module. The power supply module may comprise one or more rigid rechargeable batteries, for example of the lithium type, or flexible batteries, for example of the micro-battery type.

According to another aspect of the invention, the device comprises wireless charging means, that is to say remotely, for example by induction, of the power supply module. Such wireless charging means preferably comprise a charging antenna configured to receive electrical energy by inductive coupling.

Advantageously, the charging antenna, which may be of flexible ferrite type, is connected to the power supply module by a fourth electrical link, preferably flexible. The device may further comprise connection means, for example a connector of the Universal Serial Bus (USB) type, for connecting a charging cable of the power supply module via a fifth electrical link, preferably flexible. Advantageously, the device comprises an ignition module configured to, on the one hand, switch the device into active use mode, for example, when a movement or a user of the sole is detected and, on the other hand, Alternatively, switch the device to standby or shutdown mode, for example, when no movement or user of the soleplate is detected. Such an ignition module makes it possible to optimize the use of the device and thus to reduce its energy consumption.

To do this, the ignition module can, for example, include a weight sensor, a strain gauge or a motion sensor. A weight sensor or a strain gauge, for example mounted on or in the soleplate, makes it possible to detect the presence of a foot in the boot comprising the soleplate so as, on the one hand, to activate the device when a foot is inserted into the shoe and, secondly, put the device in standby when the foot of the wearer leaves the shoe. The motion sensor may be, for example, of the accelerometer or piezoelectric vibration sensor type. When the device comprises an ignition module, the control module can be configured to receive from the ignition module information on the use of the device and, upon receipt of said information or a predetermined number of usage information. of the device and / or after a predetermined time interval, to determine the geographical position of the device.

The control module can thus be configured to compare an old geographical position and a new geographical position of the device and to emit a signal comprising information of the new position when it is significantly different from the old position, for example when both positions are more than 10, 20 or 50 m apart.

According to another aspect of the invention, the device may advantageously comprise one or a plurality of indicators, for example of LED diode type, in order to allow a user of the device to visualize, for example, the operating mode of the device ( active, idle, off ...), use or type of a first network, use or type of a second network etc. The functional components of the various modules may in all or part be integrated in a single component or electronic circuit, only the sensors and the antenna remaining external to said component.

Figure 3 illustrates a shoe 12 comprising a sole 14 according to the invention. In this example, the shoe 12 is a running shoe with feet but it goes without saying that the sole 14 according to the invention can be mounted in any type of shoe. III. Location device 10 Figure 4 schematically illustrates an embodiment of a geolocation device 10 configured to be inserted, for example removably, in a sole 14 according to the invention. With reference to FIGS. 2 to 4, the geolocation device 10 comprises a control module 20, a supply module 30, a single transmission antenna 40. The control module 20 and the transmission antenna 40 are connected by a first electrical link in the form of a rigid electrical connector 42.

In this example, the transmission antenna 40 is electrically powered by the control module 20 via the rigid electrical connector 42. In a variant, the transmission antenna 40 can be electrically powered directly by the power supply module 30 via a link 43.

The control module 20 and the power supply module 30 are connected by a second flexible electrical link 44, which gives flexibility to the device, which can thus be easily integrated into the base 14. a) Control module 20 The module control 20 is configured to receive from the first telecommunications network 100, via the transmission antenna 40, a plurality of first signals, to determine, from the plurality of first received signals, the geographical position of the device 10 and to send to through the second telecommunications network 200, via the transmission antenna 40, a second signal comprising said geographic position of the device 10. The control module 20 is configured to select, in a first plurality of telecommunications network, a first network of telecommunications 100 for receiving the plurality of first signals and, in a second plurality of networks u of telecommunications, a second telecommunications network 200 for the transmission of the second signal.

To this end, the control module 20 comprises a switch (switch, in English language) for selecting on the one hand, from the first plurality of networks, the first network 100 which, for example, the received signal is the most powerful and, on the other hand, among the second plurality of networks, the second network 200 of which, for example, the power of the signal emitted by one or more antennas is the highest.

Other selection criteria may be used. For example, the networks can be classified so that a priority network is always selected when the location device 10 is in the coverage area of said network.

The control module 20 comprises a memory zone (not shown) for storing the geographical position information of the device 10 and / or the control data of the device 20 such as, for example, the signal levels of the networks in the or the areas of coverage of which the device is located 10.

As illustrated in FIGS. 3 and 4, the control module 20 is in the form of a single electronic component, for example of the FPGA or ASIC type, made based on nano components.

In order to prevent the humidity from disturbing the operation of the control module 20, the control module 20 is wrapped in a tight material, for example of the polyamide resin type.

The control module can also integrate logic elements (not shown) corresponding to the management electronics of energy harvesting means 50, charge 60 or ignition 80 described below. In this case, the charging means, energy harvesting or ignition can be in the form of sensors that send the signals of the parameters they measure to the control module 20. The logic elements of the control module 20 then process said signals in order to exploit them, for example by converting them and / or returning them to the power supply module 30 for storing energy in the case of an energy load sensor or an energy sensor. energy harvest. b) Power supply module 30 The power supply module 30 comprises one or more batteries and is configured to supply power to the control module 20 and the transmission antenna 40. As illustrated in FIGS. 3 and 4, the module power supply 30 is in the form of a second electrical circuit 30, for example flexible, comprising one or more rigid rechargeable batteries, for example of the lithium type, or flexible, for example of the micro-battery type. In order to prevent the humidity from disturbing the operation of the supply module 30, the supply module 30 is wrapped in a tight material, for example of the polyamide resin type. c) Transmission Antenna 40 In this example, the transmission antenna 40 is configured to receive, from the first telecommunications network 100, a plurality of first signals and to transmit, through the second telecommunications network 200, a second signal comprising said geographical position.

In this example, the transmission antenna is a multifrequency transmission antenna, for example, to receive the first signals in the frequency band L1 (1,575.42 MHz) - L2 (1,227.60 MHz) and to transmit the second signal in the GSM 850-1900 & GSM 900-1800 frequency bands. Also in this example, the antenna 40 is flat, printed from nano components and is integrated in the material constituting the shoe sole 14.

The antenna 40 is mounted at the rear edge of the sole 14 and is substantially in the form of a semicircle of arc length of the order of V2 where λ is the wavelength of the GPS signal . d) Energy harvesting means 50 In order to dynamically charge the supply module 30 dynamically, the device 10 comprises energy harvesting means 50 configured to convert mechanical or thermal energy harvested by the device 10 in electrical energy to charge the power module 30 via a third flexible electrical link 46.

Such energy harvesting means 50 may be, for example, in the form of a piezoelectric sensor or a micro-fluid sensor such as, for example, Galinstan® (gallium alloy, indium and tin). A piezoelectric sensor makes it possible to transform the kinetic energy created during a displacement of the device 10 into electrical energy. A micro-fluid sensor exploits differences in temperature and directly transforms heat into electricity. With such a sensor, the movement of the device 10 is not necessary to generate electrical energy. The energy harvesting can thus be carried out continuously from the moment when the shoe is close to a heat source, for example when the boot is worn by a user whose foot releases heat or when the friction of the sole on the ground during the movements of the user cause heating, which increases the efficiency of energy harvesting. e) Wireless charging means 60 In order to power the power supply module 30 in a static manner, the device comprises in this example a load antenna 62, connected to the power supply module 30 by a fourth flexible electrical link 48. Such a charging antenna 62 allows remote charging, for example by induction, of the battery or batteries of the power supply module 30. 10 f) Wireless charging support 70 In order to charge the battery or batteries of the feed module 30 statically, the shoe 12 may be disposed on a load carrier 70, shown in Figure 6.

In this example, the load carrier 70 is configured to respectively charge the power supply modules 30 of two devices 10 mounted in a pair of shoes (not shown) comprising wireless charging means 60.

To this end, the load support 70 is in the form of a parallelepiped shaped plate comprising two housings 72 arranged to receive the heels of the shoes and in each of which is mounted a charging antenna 74, allowing the wireless charging to induction distance of the feed module 30 of each shoe via the load antenna 62. g) Load connector 75 The device 10 may further comprise connection means, for example in the form of a connector of the type shown in FIG. USB for connecting a charging cable (not shown) of the power supply module 30 via a fifth flexible electrical link 49. h) Ignition module 80 The geolocation device 10 comprises an ignition module 80 configured to on the one hand, to switch the device 10 into active use mode, for example, when a movement or a user of the sole 14 is detected and, on the other hand, to switch the device 10 to standby or stopping, for example, when no movement or user of the sole 14 is detected. To do this, the ignition module 80 comprises a weight sensor, a strain gauge or a motion sensor (not shown). A weight sensor or a strain gauge can be mounted on the sole 14 and can detect the presence of a foot of a user in the shoe to, on the one hand, activate the device 10 when a foot is inserted in the shoe and, secondly, put the device 10 in standby when the foot of the wearer leaves the shoe. The motion sensor may be, for example accelerometer type or piezoelectric vibration sensor. i) Indicators 90 The geolocation device 10 may comprise a plurality of indicators 90, for example of the LED diode type, visible to the user of the boot 12 in order to enable him to visualize the operating mode of the device 10 (active, in standby, off), the use or type of the first network 100, the use or the type of the second network 200 etc. The charging connector 75, the ignition module 80 and the indicators 90 have not been shown in FIGS. 3 and 4 for the sake of clarity.

IV. Another embodiment of a shoe sole according to the invention In the example described above with reference to FIGS. 3 and 4, the antenna 40 is integral with the geolocation device 10. In other words, in this example, when the device 10 is removed from the sole 14, all the elements that compose it are removed.

In another embodiment of the sole 14 according to the invention, partially illustrated in Figure 5, the antenna 40 is mounted at the rear edge AR of the sole. In other words, the antenna 40 is part of the sole 14.

In this example, the sole 14 comprises a first housing 15 for receiving the control module 20, a second housing 16 for receiving the power supply module 30 and a third housing 17 for receiving the energy harvesting module 50.

In order to receive the rigid electrical connector 42, the second electrical link 44 and the third electrical link 46, the sole 14 comprises respectively three notches 18a, 18b and 18c.

Once inserted in the first housing 15, the control module 20 can thus be connected to the antenna 40 by the rigid electrical connector 42. Description of an Embodiment of the Invention The power supply modules 30 shoes comprising the device 10 according to the invention are loaded with electrical energy when the shoes are arranged on the load support 70 according to the invention or when the device 10 is connected to a power source via the charging connector (no represent). When the user (not shown) of the device 10 moves with the shoes, the sensor 82 of the ignition module 80 detects the movement and activates the device 10. A first indicator 90 indicates the change of state of the device 10. By for example, a LED type LED changes from a red color to a green color.

When the device 10 is in motion, the energy harvesting means 50 transform the kinetic energy generated by the displacement of the device 10 or the calorific energy received by the device 10 into electrical energy so as to charge the power supply module 30.

In a first step, the control module 20 activates the transmission antenna 40 in order to select a first network 100 among the plurality of first available telecommunications networks.

The selection is made by first choosing the GPS network or, when it is not available, by choosing the first network 100 whose signal received is the highest.

Once the first network 100 has been selected, the control module 20 receives a plurality of first signals on a first reception frequency band via the transmission antenna 40 in a second stage.

A second flag 90 signals the user of the device 10 that the first selected network 100 is in use. In a third step, the control module 20 selects a second network 200 from among the plurality of second available telecommunications networks.

The selection can be made, for example, by choosing the second network 200 whose signal received is the highest. Once the second network 200 has been selected, the control module 20 transmits a signal comprising the geographical position of the device 10 on a second transmission frequency band via the transmission antenna 40 in a fourth step. A third flag 90 may signal to the user of the device 10 that the selected second network 200 is in use.

The geographical position information of the device 10 is then conveyed through the second network 200 to the server or terminal 210 which communicates it to a third party wishing to know the geographical position of the user of the device 10.

Once back home, the ignition module 80 detects the cessation of the movements of the shoes of the user and activates the standby mode of the device 10. The first indicator 90 then changes from green to red.

The user can then rest the shoes on the load support 70 and / or connect each to a power source via the charging connector 75 to recharge their power supply module 30.
