Description
“Display sign”
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the field of display signs, and more particularly signs displaying planning permits granted by local authorities. The invention will find as an advantageous but non-limiting application the field of display signs for planning application notices, building permits, demolition permits or zoning permits.
BACKGROUND INFORMATION
Developers applying for planning permission to carry out their construction projects are generally mandated to inform third parties of their application or of the authorisation granted to them (generally by the local authority), usually by means of a notice sign with regulatory codified features. In the case of France, this codification is subject to article R.424-15 of the French Urban Planning Code and associated ministerial orders.
This kind of sign can be readily found in construction materials stores or be custom-made by a printing shop. The display sign has the following mechanical characteristics in France:
• Dimensions: 80cm x 80cm minimum, typically 80cm x 120cm, thickness 3 to 7 mm • Material : Alveolar polypropylene or extruded PVC plate • Information printing technique: screen printing (for large quantities) or inkjet (for small quantities) • Fastening method: typically pass-through eyelets arranged in the four corners + free fastening by the applicant (ropes, metal wire, screws and anchors ...) on any type of support (e.g. : wired fence, wall, dedicated support made of plywood or medium density fibre ...) • Personalisation of information can be done in two manners:
o Most common case: free spaces are provided so that the applicant can themselves write (e.g. using an indelible marker) their own details o More rare: printing of custom information by screen printing or inkjet by a printing shop
This type of sign presents numerous drawbacks. They are for instance generally very fragile, a gust of wind or an act of vandalism may be enough to tear them off or to degrade them.
The erection of the sign on the plot of land then starts a period of time, which in France lasts two months, during which third parties can submit an objection against the developer under their civil rights or against the administrative authority that granted the permit.
Due to this so-called “third party objection lodging” two-month period, it is desirable for the developer to establish proof of their good faith with respect to this public display legal obligation.
According to the above mentioned laws and regulations, the display must comply with several conditions:
• Include some mandatory information ;
• Be visible from a public thoroughfare ;
• Be displayed on the edge of the plot of land on which the new development will be built;
• Remain displayed during a continuous period of two months;
In order to address the latter point above, it is frequent for the developer, notably with regards to planning permission applications, to have a judicial officer write an affidavit establishing the display of the sign. In this case, it is agreed that the judicial officer will transport themselves at the place of display three times during the two-month display period of the sign. After each on-site visit, the judicial officer writes an affidavit describing the witnessed facts (sign characteristics, place, visibility from a public thoroughfare, etc.). The affidavit may include photographs.
The affidavits are sent to the developer by post as paper originals or electronically, typically in PDF format (non-ciphered, non-electronically signed) by e-mail.
However, this type of statement by a judicial officer presents numerous drawbacks, from the economic point of view for the developer, but also in terms of legal security with respect to third parties. Indeed, although accepted in previous court cases, the low number of statements from the judicial officer (3 maximum) does not guarantee the continuity of display during the two-month objection period.
The present invention aims to solve at least partly the above mentioned problems.
SUMMARY OF THE INVENTION
The present invention relates to a display sign capable of displaying a planning permit, for instance a planning application notice, comprising at least a first portion configured to form at least partly a front surface of the display sign, the front surface of the display sign comprising a plurality of printed information, preferably said front surface defining a surface capable of being at least partly torn off, at least a second portion configured to form at least partly a rear surface, being characterised in that it comprises at least one electronics device comprising at least:
o A geolocation module capable of receiving at least one signal allowing to compute at least one location coordinate of the display sign ;
o A radiofrequency communication module configured to communicate with at least one computer server via a communication network, the radiofrequency communication module being configured to transmit at least said location coordinate of the display sign to said computer server;
o And preferably, an electrical power supply module configured to electrically power the electronics device.
The present invention thus provides a known location of the display sign, available advantageously in real time, from its erection up to its removal.
This thus ensures a continuity of display of the sign without necessitating a plurality of interventions of for instance a judicial officer in order to attest of the presence of the sign in the place where it should be.
Advantageously, the display sign according to the present invention comprises at least an attachment support to an element anchored to the ground, such as for instance a wall, a grid gate, a tree, a pole or also a wire fence.
Preferably, the front surface defines a surface capable of, at least partly, being folded and/or torn off and/or cut and/or split into several pieces, advantageously manually and/or using at least an unpowered tool, for instance a knife, a utility knife, a pair of cutter pliers. Preferably, said surface comprises at least partly said plurality of printed information.
The invention also allows the developer to avoid having to transport themselves on-site to check whether the sign is still in place and to know the location of the sign should it be moved, because of wind or a third party for instance.
The present invention also relates to a system comprising at least a display sign according to the present invention and at least one computer server communicating, for example using radiofrequency, with the display sign through a communication network via a radiofrequency communication module.
This makes it possible to have a computer server gathering all the data transmitted by the display sign so as to ensure, preferably in real time, a monitoring of the integrity of the display sign and its positioning.
The invention thus allows the developer to establish proof of their good faith with respect to their public display legal obligation in case of appeal to a jurisdiction.

Advantageously, the electronics device comprises at least one gyroscope configured to measure the display sign’s spatial orientation data, the electronics device being configured to transmit said display sign’s spatial orientation data through the radiofrequency communication module to at least one computer server.
This allows to know the spatial orientation of the sign, that is to say whether it is in a vertical, horizontal, leaning, tilted, turned, or in a combination of these spatial orientations. The attitude of the display sign is thus known and monitored so that one can intervene rapidly if necessary, and so as to ensure a traceability of said display sign and its display.

Preferably, all data borne by the front surface of the sign and preferably borne by the whole of the sign and that are meant to be viewed by an observer are static. Thus, the sign does not comprise any screen and in particular no screen the display of which evolves during the objection period.
Advantageously, the display sign comprises at least a unique identifier.
This allows to identify the display sign by associating this unique identifier to the collected data on one hand, and to the user information on the other hand.
Advantageously, the unique identifier is accessible to an observer by means of a marking, preferably printed, on a surface of the display sign.
This allows to easily and visually obtain the unique identifier of the sign using for instance a barcode, a QR code.

The present invention finds as its preferred application the field of display signs for information requiring proof of their display in a precise location during a certain duration, like for instance display signs for planning application notices.
The present invention aims to establish an affidavit of installation, visibility and integrity of a display sign, in order to avoid users having to appoint a judicial officer to draw up an affidavit or to establish additional evidence, a judicial officer’s affidavit being susceptible to being invalidated by contrary proof. Moreover, via a series of security measures that will be described hereafter, the present invention ensures the security of position, visibility and integrity data as well as their certification.
The present invention allows multi-level data security through the control of the display sign’s physical integrity, its geographical position, its orientation, its display and through ciphering of data.
As we will see below, computer protocols are also implemented to ensure the integrity of data and operating algorithms.
The present invention thereby offers a guarantee with respect to the user’s compliance with regulatory obligations.
We will now outline the present invention in its diverse aspects by means of various figures.
> Example use case according to an embodiment of the present invention
According to an embodiment, the present invention targets a user, a building owner for instance, wishing to obtain a proof of display of information to third parties at a lower cost than a judicial officer’s affidavit for instance and wishing to ensure the continuous visibility of said information over time, or even in real time.
Figure 1 illustrates a deployment scenario of the present invention according to an embodiment. This figure thus represents a house 1 for instance subject to extension works planned at the expiry of the third-party objection period and built on a plot of land comprising a tree 3 to which is affixed a display sign 20 according to an embodiment of the present invention. The plot of land comprises the house 1 and is bordered by a low wall 4 separating it from a public thoroughfare 2.
Preferably, the display sign 20 is placed at some height so as to be visible beyond the wall from the public thoroughfare 2.
This use case illustrates for instance a good example of problems that can occur during the display of the display sign. For example, it could unfasten, fall to the ground tipped over by the wind, be subject to acts of vandalism or even a tree branch could fall and obscure the visibility of information on the display sign. As we will see later, the present invention allows the user to be informed of such events even when the user is not on site and thus allows them to intervene.
Figure 2 represents a display sign 20 according to an embodiment of the present invention, and more particularly the front surface intended for the display of a planning application notice. This display sign 20 comprises a front surface comprising a plurality of printed inscriptions, and a plurality of non-printed areas 22 intended to receive a printed and/or handwritten inscription specific to the user.
The display sign 20 according to an embodiment of the present invention is preferably pre-printed in compliance with regulatory requirements.
In addition this display sign 20 is advantageously configured to communicate with a satellite system 10 on one hand and with at least one computer server 40 on the other hand. To this effect, and according to a preferred embodiment of the present invention, the display sign 20 comprises an electronics device 200 comprising at least one geolocation module 220, a radiofrequency communication module 230 and an electrical power supply module 203.
Preferably, the electrical power supply module 203 is configured to electrically power the electronics device 200 advantageously for a duration matching the regulatory display period, for instance 2 months for a building permit.
Figure 3 illustrates a schematic representation of the data flow according to an embodiment of the present invention. On this figure, geolocation data, preferably ciphered, are transmitted from a satellite system 10 to the display sign 20. The display sign 20 communicates with a computer server 40 via at least one communication network 30 so that the computer server 40 can deliver an affidavit 50 to the user relating, amongst other things, to the geographical position of the display sign 20.
According to a preferred embodiment, the display sign 20 is configured, via its geolocation module 220, to obtain geolocation coordinates from these satellite systems 10 such as Global Positioning System, Glonass, Galileo for instance.
Thus, the display sign 20 according to an embodiment reports its geographical position, preferably at regular time intervals, to a computer server 40 automatically and without any other intervention from the user than to install it at the edge of the plot of land so as to be visible from the public thoroughfare 2, like with a traditional display sign.
Moreover, and in order to ensure the validity of the data that the display sign 20 receives and transmits, the display sign 20, via its electronics device 200, is configured to secure said data for instance by encrypting them with a ciphering key.
According to a preferred embodiment, transmissions from the display sign 20, via the electronics device 200, to the computer server 40 may be ciphered and authenticated so as to ensure confidentiality of the data and their correct and un-tampered attribution to a user whose data associated to the display sign 20 are managed by the computer server 40.
Transmissions from the display sign 20 via the electronics device 200 to the computer server 40 are preferably performed wirelessly by means of, for example, radiofrequency technologies and communication protocols such as Low-Power Wide Area Network (LPWAN), LoRa, Sigfox, and/or digital cellular technologies and protocols such as SMS (“Short Message Service”) / GSM (“Global System for Mobile”) / HSCSD (“High Speed Circuit Switched Data”) / GPRS (“General Packet Radio Service”) / EDGE (“Enhanced Data Rates for GSM Evolution”) / WCDMA (“Wideband Code Division Multiple Access”) / HSPA (“High Speed Packet Access”) / LTE (“Long Term Evolution”) 4G / 5G, etc..., or more generally any type of wireless communication technologies and protocols; these technologies and protocols being well known by one of ordinary skill in the art.
According to an advantageous embodiment, the electronics device 200 handles the monitoring of the position of the display sign 20 continuously while alerting the user in case of anomalies, or so-called “alerts”, such as for instance a defect in its physical integrity or events detected by sensors.
Preferably, this electronics device 200 is designed to transmit data related to said events and to the physical integrity of the display sign 20, using an integrity module 210 comprising at least one or several sensors. This integrity module 210 thus allows the present invention, according to a preferred embodiment, to detect and transmit to the computer server 40 events likely to compromise the legal standing of the display or the physical integrity of the display sign, for instance: displacement, laceration or cut because of the wind or vandalism, fall of the display sign or change in its orientation, or even fall of items in front of the display sign 20 reducing its visibility.
The questions of physical integrity will be elaborated upon hereafter.
Advantageously, the electronics device 200 enables the execution of a computer program product stored in a non-volatile memory which performs functions described hereafter, notably the regular and automatic transmission to a computer server 40 of the position of the display sign 20 to which a unique identifier is advantageously allocated.
Thus, beyond the physical integrity of the display sign 20, the present invention also seeks to ensure the integrity of the execution of the computer program by electronic and software techniques such as « Secure Element » (SE) or « Trusted Execution Environment » (TEE), well known by one of ordinary skill in the art, storing a ciphering key for decrypting the computer program before its execution and preventing the execution of an illegitimately modified computer program.
Those skilled in the art may refer to numerous works of the prior art relating to these wellknown techniques, including for example : Swaminathan, S., Rawat, S., Coogan, G. et Vanderhoof, R., “Mobile/NFC Security Fundamentals - Secure Elements 101”, Smart Card Alliance Webinar, March 28th 2013, or also A. Vasudevan, E. Owusu, Z. Zhou, J. Newsome, and J.M. McCune, “Trustworthy Execution on Mobile Devices: What security properties can my mobile platform give me?” in Trust and Trustworthy Computing, vol. 7344 of LNCS, pp 159-178. Springer, 2012.
The present invention also allows the detection of operating anomalies of the electronics device 200 such as software reboots, a low battery level or an interruption of the electrical power supply, a loss of the geolocation satellite signal or of the communication network 30.
All these measures, whether relating to events likely to alter the compliance of the display, to the physical integrity, to software integrity, to operating integrity or to data ciphering allow the present invention to safeguard the validity of data received by the computer server 40 which allows to generate an affidavit 50 for the user.
Thus the present invention allows on the one hand the display of mandatory information in accordance with laws and regulations, pre-printed on the front surface according to classical printing techniques. According to an embodiment, the display sign 20 may comprise one or more customisable fields displayed digitally, using for instance OLED (“Organic Light-Emitting Diode”) screens, LED (“Light-Emitting Diode”) screens, LCD (“Liquid Crystal Display”) screens or even e-ink (“Electronic Ink”), etc.., such display devices being well known to one of ordinary skill in the art.
And on the other hand, the display sign 20, via the electronics device 200 that it comprises, benefits from a unique identifier, associated to a user at a computer server 40, allowing the digital review and controlled distribution of for instance information associated to the display sign 20, and in real-time for example.
Thus, according to an embodiment, the present invention may require only a single visit by a judicial officer in order to provide a visual determination of the displayed information relative to the unique identifier of the display sign 20. Once such a determination is performed, the conventional affidavit may be digitalised and associated to the unique identifier of the display sign 20 at the computer server 40. The positioning data integrity and the physical integrity of the display sign 20 then avoid the need for another visit by the judicial officer.
According to another embodiment, the visit of a judicial officer may be avoided by calling upon third-parties by means of an internet platform in the form of a software application or a web page for example.
The present invention thus relates to a software, or even web, observation platform that can be executed on a mobile device such as a smartphone for example, and is designed to allow third parties to make a statement and remarks when they are in the vicinity of the display sign 20, this allowing to detail that the display sign 20 is indeed visible from the public thoroughfare 3 for instance and to detail the information that it comprises, or even to send a photograph of the display sign 20.
Thus this platform may allow to take at least one picture of the display sign 20 and to cipher it on the computer server 40, with which the platform is in communication, so as to safeguard the displayed information, as well as the association with, or advantageously the embedding of, the shooting time and location of the mobile device that enabled the realisation of the statement with the shooting.
Thus, according to one embodiment, the unique identifier of the display sign 20 can be broadcast in the vicinity of the display sign 20 via technologies such as number, barcode / QR code printed on the front surface or also via an RFID transponder, a Bluetooth beacon, or even a Bluetooth Low Energy beacon.
This broadcasting of the unique identifier allows a third party, via the dedicated observation platform, to retrieve the unique identifier of the display sign 20 and either to describe it by answering a series of questions, or to report any anomalies, or even to submit their objections against a future building in the case of a planning application.
According to an embodiment, the present invention thus relates to a method for ascertaining the display of information of the display sign 20.
This method, preferably, but in a non-limiting way, may comprise the following steps:
o Retrieval of the unique identifier of the display sign 20 by an observer;
According to another embodiment, a correlation is established between the position of the observer and that of the nearest display sign 20, so as to infer its unique identifier;
o Transmission of the unique identifier to the computer server 40 via a communication device, preferably portable, such as a smartphone for instance ;
o Reception from the computer server 40 of a questionnaire to be filled in on the observer’s communication device ;
o Transmission of the filled-in questionnaire from the communication device to the computer server 40 ;
o Advantageously, transmission of one or several photographs of the display sign 20 taken by the observer using the, preferably portable, communication device, such as a smartphone for instance ;
o Advantageously, transmission of the observer’s location ;
o Advantageously, transmission of the shooting time (date and hours / minutes / seconds);
o Association of the questionnaire with the unique identifier, and advantageously of the photograph(s) with the unique identifier and advantageously of the date and time, and of the observer’s location.
This method for ascertaining the display of information of the display sign 20 may be implemented in a computer program by means of an algorithm itself stored in a memory and readable by at least one microprocessor in the form of instructions. This algorithm being possibly stored at the computer server 40 or at the observer’s communication device.
The use of third-party observations then allows to constitute a plurality of proofs without requiring the visit of a judicial officer because of the security and data validation on the computer server 40.
We will now describe, according to one embodiment, the mechanical characteristics of a display sign according to the present invention.
> Mechanical description of a display sign according to an embodiment of the present invention
Figure 4 represents a schematic exploded view of a display sign 20 according to an embodiment of the present invention.
On this figure, the display sign 20 comprises a first portion 23 and a second portion 24.
The first portion 23 is configured to form a front surface of the display sign 20. According to an embodiment, the front surface comprises at least one area of printed information 21 and/or at least one area for customisable inscriptions 22, being possibly handwritten, printed, and/or digital.
According to an embodiment, the customisable information on the front surface may optionally be displayed by one or several digital displays. Such displays will be preferably embedded into cavities machined in the material of the front surface when manufacturing the display sign 20.
The front surface is preferably square or rectangular in shape, and of dimensions in compliance with local regulations.
The first portion 23 may comprise materials of type PVC, alveolar polypropylene sheet, wood/plywood/MDF, cardboard or their equivalent. According to an embodiment, the front surface 23 may be a self-adhesive film made of a material such as vinyl protected against weather by hazards rain- and ultraviolet- resistant filming.
The second portion 24 is configured to form the rear surface of the display sign 20.
The second portion 24 may comprise materials of type PVC, alveolar polypropylene sheet, wood/plywood/MDF, cardboard or their equivalent.
According to an embodiment, the sign 20 comprises only the first portion 23, the second portion 24 and the electronics device 200.
According to an embodiment, one or the other of portions 23 and 24 may comprise one or several photovoltaic panels destined to power at least partly the electronics device 200.
The rear surface has dimensions identical to the front surface. The second portion 24 may comprise any rigid or semi-rigid material, preferably identical to that or those of the first portion 23.
Advantageously, a cavity 25 is machined into the bulk of the second portion 24 allows the installation of the electronics device 200 previously placed into an enclosure 26.
According to another embodiment that will be detailed hereafter, said cavity 25 may be formed by a pass-through cut-out 29 of the second portion 24 and/or the first portion 23 of the display sign 20. This then allows simplified manufacturing and easy withdrawal by the user of the electronics device 200.
On the side into which said cavity 25 is machined, the second portion 24 is preferably, and according to an embodiment, covered by an adhesive, this adhesive being used to glue together the first 23 and second 24 portions when manufacturing the display sign 20 and to sandwich the enclosure 26 and advantageously the tripwire 201 that will be described hereafter.
Preferably, the thickness of the second portion 24 is sufficient to allow insertion of the enclosure 26 into the cavity 25 without creating any bulge once the first portion 23 is glued to the second portion 24.
Advantageously, when machining a pass-through cut-out 29 into the second portion 24 and/or the first portion 23 of the display sign 20, and once the electronics enclosure 26 is placed within the pass-through cut-out 29, the latter may be sealed by an adhesive film hereafter designated as rear film 28. This allows to isolate the electronics enclosure 26 from the outside.
In figure 4, the electronics device 200 is placed, at least partly, into an enclosure 26, preferably sealed with a lead seal so as to ensure its physical integrity.
This enclosure 26 is preferably waterproof.
According to a preferred embodiment, this enclosure 26 is filled with a resin so as the electronics device 200 is cast within said resin, in order to prevent any access to the internal electronics components of the electronics device 200 without destroying the latter.
This enclosure 26 may provide several terminals allowing to connect various elements including for instance : one or several radio antennas, a tripwire 201, an electrical power supply by photovoltaic cells for example or by batteries for example, one or several displays, one or several optical sensors. The connectors for these terminals may be waterproof.
Figures 8a, 8b, 9, 10 and 11 illustrate a preferred embodiment of the present invention according to which the enclosure 26 comprises at least one shell 26a. The shell 26a is shaped to house at least the electronics device 200. The shell 26a is preferably configured to have its front portion closed by a front film 27.
According to this embodiment, the shell 26a may be made of low thickness plastic materials, preferably the thickness of which is between 0.1mm and 4mm.
Particularly cleverly, the shell 26a comprises a material transparent to electromagnetic waves, and particularly those required for the operation of the electronics device 200, and preferably the geolocation module 220 and/or the radiofrequency module 230.
Advantageously, the shell 26a may be made from a thermoformed material so as to externally fit the contour of the cavity 25 and/or the pass-through cut-out 29, while being shaped to accommodate the electronics device 200 and its different constitutive modules, among which the power supply module 203, which may for instance comprise a battery of type Lithium-Ion or Lithium-Polymer.
Figure 8a and 8b represent an embodiment of shell 26a. This shell 26a may thus provide, for instance, one or several housings 26b for the electronics device. More precisely, it can provide a housing 26c for the electronics board 205 of the electronics device 200 and a housing 26d for the electrical power supply module 203.
Preferably, shell 26a provides an external edge comprising a spatial extension thereafter called rims 26f. These rims 26f are configured to ensure shell 26a holds in the cavity 25 and/or the pass-through cut-out 29 realised in the first 23 or the second 24 portion of the display sign 20.
In addition these rims 26f are also configured to advantageously bear at least two electrically conductive connections 26e, preferably formed in the bulk of shell 26a at the edge of shell 26a. These two electrically conductive connections 26e are configured to electrically connect the electronics device 200 housed in the shell 26a and a tripwire 201 that will be more precisely described hereafter.
Advantageously, said electrically conductive connections 26e are located on the lower surface of rims 26f so as to be in electrical contact with the ends of the tripwire 201 described thereafter once the display sign 20 is assembled.
Advantageously, the rims 26f are said to be flush with one and/or the other of the first 23 and second 24 portions of the display sign 20. This thus allows to shell 26a to fit the contour of the cavity 25 and/or of the pass-through cut-out 29, so as the mechanical stability of shell 26a within the cavity 25 and/or the pass-through cut-out 29 is ensured.
According to an embodiment, the rear portion of shell 26a, visible in figure 8b for instance, provides a plurality of slanted surfaces 26g. These slanted surfaces allow to easily fit the shell 26a within the cavity 25 or the pass-through cut-out 29. In addition, these slanted surfaces 26g allow the vertical outflow of water that may drip through the cells of the display sign 20 if the latter comprises a portion made of alveolar polypropylene. Indeed, in the case where one of the first 23 and/or the second 24 portion of the display sign 20 comprises alveolar polypropylene, the inside of the display sign 20, at least partly, provides cells forming dripping channels for rainwater for instance. It is therefore advantageous that the electronics device 200 be placed within a waterproof enclosure 26 and/or a shell 26a closed in a water-tight fashion. In addition, the slanted surfaces 26g help the outflow of water within the display sign 20 when it rains.
We will note that the shell 26a advantageously provides recesses for electrical connections between the electrical power supply module 203, the electronics board 205 and the tripwire 201 described hereafter.
According to an embodiment, the shell 26a provides in its housings 26b, 26c, 26d studs for attaching the electronics board 205 and/or the electrical power supply module 203. These studs are advantageously configured to ensure the mechanical holding of the electronics board 205 and/or the electrical power supply module 203 in their housings 26c and 26d respectively.
Figure 9 thus represents, according to an embodiment of the present invention, the electronics device 200 placed in its housings 26b, 26c, 26d within the shell 26a. Advantageously, the electronics board 205 supporting a plurality of modules 210, 220, 230, 240 of the electronics device 200 is placed within its housing 26c and the electrical power supply module 203 is also placed within its housing 26d. We thus find at least the switch 202, the accelerometer 212, the geolocation module 220, the radiofrequency communication module 230 and the microcontroller 240 supported by the electronics board 205.
Finally, as described hereafter, the front part of the shell 26a is configured to be closed, preferably hermetically and in a water-tight fashion, by at least one front film 27.
This front film 27 comprises preferably a plastics material. This front film 27 is advantageously thermally glued on the rims 26f of shell 26a. Another solution consisting in this front film 27 being a self-adhesive film, for instance made of vinyl, and glued on the rims 26f of shell 26a, and preferably also on an internal surface of the portion of the display sign 20 comprising the cavity 25 and/or the pass-through cut-out 29.
According to an advantageous and preferred embodiment, the electronics device 200 is configured to cooperate with at least one tripwire 201 laid out in between the first portion 23 and the second portion 24 of the display sign 20.
According to an embodiment, the electronics device 200 cooperates with the tripwire 201 through the integrity module 210.
This tripwire 201, visible in figure 4 and in figures 10 and 11, is configured so that a cut of the tripwire 201 is detected by the electronics device 200, for example at the integrity module 210.
Particularly advantageously, the tripwire 201 is laid out so as to form a geometrical shape, preferably defining a closed contour, presenting an interior area amounting to at least 25% and preferably 50% and advantageously 75% of the total area of the first portion 23 and/or the second portion 24.
Advantageously, the tripwire is laid out randomly in between the first portion 23 and the second portion 24 of the display sign 20.
Preferably, as illustrated in figure 4, the tripwire 201 is laid out so as to form a series of back-and-forth roundtrips from one edge of the display sign 20 to an opposite edge while spreading on the overall surface of the first portion 23 and/or the second portion 24 of the display sign 20.
According to an embodiment, the tripwire 201 draws serpentine shapes between the first portion 23 and the second portion 24 of the display sign 20.
With the tripwire 201, if the front surface of the display sign 20 is lacerated, cut or otherwise torn off, the user is warned by the transmission of an alert from the electronics device 200 to the computer server 40.
Advantageously, the tripwire 201 presents a fragile-enough mechanical structure to be cut at the same time as the display sign is torn or cut or when the two portions 23 and 24 of the display sign 20 are disjoined from one another. Advantageously, the tripwire 201 presents a fragile-enough mechanical structure to snap from the moment that the structural integrity of the front surface of the display sign 20 is altered.
This snapping of the tripwire 201 then corresponds to the break of an electrical circuit configured to be detected by the electronics device 200 which then transmits this breaking event to the computer server 40 via the radiofrequency communication module 230 so as to warn the user of an anomaly via the triggering of an alert at the computer server 40.
According to another embodiment, the snapping of the tripwire 201 may lead to a stop in the electrical power supply of the electronics device 200 so as the computer server 40, having no communication anymore with the display sign 20, triggers an alert for the user to inform them of the detection of an anomaly.
Advantageously, the tripwire 201 may cooperate with the radiofrequency communication module 230 as a radio antenna. In this case, and preferably, the geometrical layout of the tripwire 201 is designed so as to allow a good reception of electromagnetic signals while ensuring its role in the integrity control of the front surface as described previously.
According to a particular embodiment, the tripwire 201 is an optical fibre. The snapping of the tripwire 201, in this case, implies a discontinuity of a luminous flux. This discontinuity is then detected by the electronics device 200, via for example the integrity module 210.
Figure 10 represents a perspective view of the second portion 24 of the display sign 20 housing the electronics device 200 advantageously housed within the shell 26a. In that figure, we will note the electrically conductive connections 26e, preferably placed at the external edge of shell 26, particularly at the level of rims 26f of shell 26a. These electrically conductive connections 26e are advantageously configured to electrically connect by contact the tripwire 201 with the electronics device 200.Thus, advantageously, the two ends of the tripwire 201 are terminated by electrical terminals placed at the edge of the cavity 25 and/or the pass-through cut-out 29 so as to be facing opposite of the electrically conductive connections 26e of the enclosure 26 and/or the shell 26e of the electronics device 200.
We will now describe with figure 11 an exploded view of an embodiment of the present invention wherein the electronics device 200 is housed within a shell 26a. The shell 26a is closed at its front by a front film 27. This shell 26a is configured to fit within a pass-through cutout 29 realised in the second portion 24 of the display sign 20. We will note that a rear film 28 of a nature similar or different to that of the front film 27 is configured so as to close off the passthrough cut-out 29 preferably at the level of an exterior surface of the display sign 20, and in particular at the level of the exterior surface of the second portion 24 of the display sign 20. This rear film 28 ensures the water-tightness of the interior of the pass-through cut-out 29. These front 27 and rear 28 films are configured to be removable by the user when the latter wishes to remove the electronics device 200 from the display sign 20, for instance when returning said electronics device 200 by mail or for maintenance.
This rear film 28 may comprise a self-adhesive vinyl film. Preferably, instructions may be written on this rear film 28.
Advantageously, said pass-through cut-out 29 is closed off by the rear film 28, preferably adhesive or self-adhesive, the area of which is greater than the open area of said pass-through cut-out 29.
Thus, figure 11 presents from left to right a stacking of the following items:
- First portion 23 of the display sign 20 ;
- Front film 27 configured preferably to seal off shell 26a ;
- Electronics board 205 and electrical power supply module 203 ;
- Shell 26a ;
- Tripwire 201 ;
- Second portion 24 of the display sign 20 comprising the pass-through cut-out 29 ;
- Rear film 28 configured preferably to seal off the pass-through cut-out 29 from the outside of display sign 20.
This embodiment thus allows some modularity for the electronics device 200 which then becomes removable from the display sign 20. We will note that the removal of the electronics device 200 will advantageously incur the break of the electrical contact between the electronics device 200 and the tripwire 201.
The use of a shell 26a as described herein allows the electronics device 200 to be housed within the thickness of the display sign 20.
This also allows the extraction of the electronics device 200 from one of the surfaces of the display sign 20 without requiring the destruction of the display sign 20 and while ensuring the detection of this removal.
We will now describe in more detail the electronics device according to an embodiment of the present invention.
> Electronical description of the electronics device of the display sign according to an embodiment of the present invention
According to a preferred embodiment, the electronics device comprises at least a geolocation module 220, a radiofrequency communication module 230 and an electrical power supply module 203.
Advantageously, the geolocation module 220 is configured to compute location coordinates at the Earth’s surface thanks to signals broadcast by a satellite system 10 which may comprise a plurality of satellites.
According to an embodiment, this geolocation module 220 is configured to operate with a plurality of satellite systems 10 in order to ensure the regular acquisition of signals and the computation of the position of the display sign 20 even though a satellite system 10 amongst the plurality may be unreachable.
According to another embodiment, this geolocation module 220 is configured to communicate concurrently with a satellite system 10 and one or a plurality of ground-based coordinates computation accuracy augmentation system(s), such as those complying with the RTCM (“Radio Technical Commission for Maritime Services) standards and NTRIP (“Networked Transport of RTCM via Internet Protocol”) protocols (for instance the PPP “Precise Point Positioning” of the Centre National d’Etudes Spatiales).
According to another embodiment, this geolocation module 220 is configured to communicate with an encrypted satellite system 10 so as to allow the certification of received positioning data, like for instance by using the Galileo (“Commercial Service” or “Public
Regulated Service”) satellite system 10.
Thus, and according to an advantageous and preferred embodiment, the geolocation module 220 is configured to operate in cooperation with the Galileo satellite positioning system.
The radiofrequency communication module 230 may comprise a plurality of sub-modules, some for so-called short-range communication, namely at a distance less than several tens of meters, others for communication at a greater range.
As described previously, this radiofrequency communication module 230 may comprise various communication technologies and protocols adjustable to the environment of the display sign 20 and also to the applicable local regulation.
The electrical power supply module 203 may comprise a battery configured to electrically power the electronics device 200 for at least the planned display sign 20 display duration, and advantageously beyond.
According to an embodiment, the electrical power supply module 203 may comprise one or several connection terminals to one or several external energy sources such as for instance a residential mains power supply, solar panels or even an external battery.
According to an embodiment, the electronics device 200 is provided with electrically conductive connections 26e destined to be in electrical contact with the ends of the tripwire 201 in such a way that the electrical connection is established when the enclosure 26 or the shell 26a is inserted in the cavity 25 or in the pass-through cut-out 29.
The integrity module 210 is configured to evaluate the integrity of the display sign 20 by measuring at least one variable.
According to a preferred embodiment, this measured variable may be the electrical continuity of the tripwire 201 so that its severance is evaluated by the integrity module 210 in order to transmit the severance information to the computer server 40 via the radiofrequency communication module 230.
According to another embodiment, perfectly compatible with the previous one, a plurality of variables is measured, which may include a change in spatial orientation of the display sign 20 via data collected from a gyroscope 211, or even from an accelerometer 212, or a magnetometer. This type of sensor for instance provides information about the position, orientation and displacement of the display sign 20. Their measurements allow to detect all modifications of these characteristics and thus lead to an assessment of the visibility of the display sign 20.
According to an embodiment, as soon as changes in orientation, in position or even in motion are detected and sent to the computer server 40; then said computer server 40 generates a user alert.
According to an embodiment, by using maps and plans previously recorded in the computer server 40, or accessible to said computer server 40, as soon as changes in orientation, in position or even in motion are detected, the computer server 40 evaluates on the basis of its maps and plans whether or not the front surface of the display sign 20 is still visible by third parties. This evaluation may be supplemented by one or several optical sensors 213.
Indeed, the integrity module 210 may comprise one or several optical sensors 213 laid out through openings in the front surface of the display sign 20 so as to evaluate whether or not the latter is illuminated, thereby informing at least partly on third-party visibility.
For instance, in the case of an optical sensor 213, the latter being preferably placed on the front surface of the display sign 20, if a change in light intensity exceeds certain thresholds, that information is sent to the computer server 40 so as to compare this data with those from other sensors. Thus, if the display sign 20 falls on its front face, the optical sensor 213 will indicate a strong change in luminosity and the accelerometer 212 and the gyroscope 211 will indicate the fall and the new attitude of the display sign 20. The combination of such measurements will thus reinforce their validity.
According to an embodiment, the integrity module 210 may comprise a thermal sensor destined to measure the temperature at the surface of the display sign 20. This thermal sensor thus allows, in the event of combustion of the display sign 20 or if it is subject to a high temperature, to transmit to the computer server 40 a high-temperature alert, as such a measured temperature being likely to incur a degradation of the display sign 20.
Advantageously, a temperature threshold may be pre-determined depending on the materials and/or inks used for the front surface of the display sign 20 so as to trigger the transmission of a high-temperature alert to the computer server 40 as soon as this threshold is exceeded.
Figure 5 illustrates a schematic representation of the electronics device 200.
According to an embodiment, the electronics device 200 may comprise:
At least one tripwire 201 as previously described ;

o At least one LPWAN antenna 234 ;
o At least one sub-module for short-range communication of type RFID or Bluetooth, i.e. in the vicinity of the display sign 20, for instance a few tens of meters

At least one so-called “non-transient” Flash memory 243 and comprising at least said computer program ;
At least one display or light-emitting diode (LED) 245.
Thus, according to a preferred embodiment, the electronics device 200 comprises at least one microcontroller 240, at least one source of electrical power supply 203, at least one transient memory 244 and at least one non-transient memory 243 storing a computer program product comprising instructions executable by said at least one microcontroller 240, said instructions being configured to execute an operating method according to the present invention as described below.
We will now describe a method for managing the electronics device, according to an embodiment.
> Description of a method for managing the electronics device of the display sign according to an embodiment of the present invention
Figure 6 illustrates a software algorithm for managing the present invention according to a preferred embodiment.
This algorithm illustrates schematically a method for managing the display sign 20 and more precisely data received and sent by the electronics device 200 according to an embodiment.
According to an embodiment, this method may comprise the following steps:
Start 301 of the method ;
Initialisation 302 of the electronics device 200 and arming of alarms with predetermined periodicity (e.g. every hour or every 24 hours) that will be triggered by the Real Time Clock 241 (RTC) ;
Retrieval of a ciphering key 303 by the electronics device 200, preferably from the computer server 40 via the communication network 30 and the radiofrequency module 230 ;
Control 304 of the real time clock 241 and the microcontroller 240 ;
o In the case where the real time clock 241 has triggered a predefined alarm, the geolocation module 220 is used to retrieve 314 geolocation data of the display sign 20 from a satellite system 10.
Then geolocation data 315 (latitude, longitude, accuracy) are ciphered 316 with the ciphering key 317 in combination with the unique identifier 318 of the display sign 20 ;
These encrypted data are then transmitted 319 to the computer server 40 via the communication network 30 by the radiofrequency communication module 230 ;
Control 305 of the sensors of the integrity module 210, preferably of the occurrence or not of an event measured by the sensors;
o In the case where an event has been detected, the type of sensor that measured the event is determined 307, and its data related to the event are retrieved 306 by the microcontroller 240, then according to rules preestablished at the microcontroller 240, a decision 308 is taken on whether or not to transmit the event data to the computer server 40 ;
In the case where a decision to transmit data is taken :
• The geolocation module 220 is used to retrieve 314 the geolocation data of the display sign 20 from the satellite system 10 ;
• The event’s data 307 and/or the geolocation data 315 (latitude, longitude, accuracy) are then ciphered 316 with the ciphering key 317 in combination with the unique identifier 318 of the display sign 20 ;
• These encrypted data are then transmitted 319 to the computer server 40 via the communication network 30 by the radiofrequency communication module 230 ;
In the case where the event is deemed irrelevant with respect to pre-established rules, data transmission is not required ;
Control 309 of the tripwire 201 and/or the status of the electrical power supply module 203:
o If the tripwire 201 is severed, or if the power supply is below a so-called low predetermined value, the retrieval 310 of the type of integrity data 311 occurs (low battery level, and/or tripwire deteriorated) ;
Advantageously, this so-called low energy level corresponds to a predetermined energy level allowing geolocation and data transmission operations but approaching a predetermined critical level below which geolocation and data transmission operations cannot be performed.
o A control 312 of the level of electrical power supply is 203 is performed ;
o In the case where the energy level of the electrical power supply module 203 is deemed insufficient, meaning greater than a predetermined critical value allowing geolocation and data transmission operations, the following operations are performed :
• The geolocation module 220 is used to retrieve 314 the geolocation data of the display sign 20 from the satellite system 10 ;
• The integrity data 311 and/or the geolocation data 315 (latitude, longitude, accuracy) are then ciphered 316 with the ciphering key 317 in combination with the unique identifier 318 of the display sign 20 ;
• These encrypted data are then transmitted 319 to the computer server 40 via the communication network 30 by the radiofrequency communication module 230 ;
o In the case where the energy level of the electrical power supply module 203 is lower than a critical value, then the electronics device 200 shuts down and the method stops 313, the absence of data received by the computer server 40 is then interpreted as an anomaly alert and sent to the user.
According to an embodiment, this method can repeat itself continuously or periodically.
This operating method may be implemented in a computer program by means of an algorithm itself stored in a memory and readable by at least one microprocessor in the form of instructions. Preferably, the algorithm for this method may be integrated to the microcontroller 240.
The present invention thus relates to a method allowing the control of the position, the physical status, but also the energetical status and the algorithmic status of the display sign 20 by using one or several sensors and control software.
All sensors and modules are thus designed to transmit any operating anomaly originating from an external event so as the user is informed preferably in real time and may intervene to correct said anomalies.
> Description of a method for detecting a shock sustained by a display sign according to an embodiment of the present invention
According to an embodiment, the present invention relates to a method for detecting a shock sustained by the display sign 20.
This method advantageously uses a sensor, such as an accelerometer 212 for instance, capable of measuring at least one acceleration of the display sign 20 relative to a spatial direction, preferably relative to the three directions in space. This sensor is configured to cooperate with the electronics device 200.
According to an embodiment, the method for detecting a shock comprises the following steps:
o Measurement of at least one acceleration along at least one of the spatial directions by the sensor, preferably the accelerometer 212; ;
o In the case where the measured acceleration exhibits a value greater than a predetermined value, transmission from the radiofrequency communication module 230 to a computer server of a shock detection alert.
This method allows the detection of a shock sustained by the display sign 20 and may be correlated with detections of other events to corroborate hypotheses and avoid false positives indicating for instance a motion of the display sign 20.
In addition this method allows the transmission of an alert that may lead to the operation of other methods like for instance a method for detecting a displacement that will described hereafter.
> Description of a method for detecting a tilt of a display sign according to an embodiment of the present invention
According to an embodiment, the present invention relates to a method for detecting the tilt of the display sign 20. This tilt is preferably measured relatively to a pre-established reference frame, such as for instance relatively to the cardinal points or to the horizon, or preferably to a reference tilt determined at the time of installation of the sign.
This method advantageously uses a sensor capable of measuring at least one tilt of said display sign relative to a spatial direction, preferably relative to the three directions in space. This sensor is configured to cooperate with the electronics device 200.
According to this embodiment, the method for detecting a tilt comprises the following steps:
o Measurement of a tilt relative to at least one of the spatial directions by said sensor;
o In the case where the measured tilt exhibits a value greater than a pre-determined value, transmission from the radiofrequency communication module 230 to a computer server of a detection alert of a tilt of the display sign 20.
Such a sensor may for instance be a gyroscope 211 or even a digital spirit level.
This method allows the detection of a fall of the display sign 20 for instance.
> Description of a method for detecting a displacement of a display sign according to an embodiment of the present invention
According to an embodiment, the present invention relates to a method for detecting a displacement of the display sign 20.
This method advantageously uses the geolocation module 220 of the electronics device 200 to acquire a geolocation signal and perform a position computation when an acceleration or a tilt is measured.
According to this embodiment, the method for detecting the displacement comprises the following steps:
o Acquisition of geolocation satellite signals originating from at least a plurality of satellites ;
o Computation of the current position of the display sign 20 on Earth’s geodetic datum; o Computation of the distance between the computed current position and a predetermined reference position when the display sign 20 is installed for instance ;
o In the case where the computed distance exhibits a value greater than a predetermined value, transmission from the radiofrequency communication module 230 to a computer server of a detection alert for a displacement of the display sign 20.
Advantageously, the automatic detection of a displacement allows to reinforce the reliability of the display sign apparatus 20 by ensuring that the user will be warned in case of displacement of the display sign 20.
We will now describe an embodiment of a method for manufacturing a display sign according to the present invention.
> Description of a method for manufacturing a display sign according to an embodiment of the present invention
Figure 7 and 12 each represent a diagram describing a method for manufacturing a display sign 20 of the present invention according to two embodiments.
According to the embodiment represented in figure 7, the manufacturing method may comprise the following steps:

Deposit 405 of an adhesive on a surface of the first portion 23 and/or a surface of the second portion 24 ;
Installation 408 of the tripwire 201 in between the first portion 23 and the second portion 24 and connection of the tripwire 201 to the electronics device 200 ; Advantageously, the ends of the tripwire 201 are terminated by electrical contact terminals. Advantageously, the tripwire is laid out randomly in between the first portion 23 and the second portion 24.
Configuration 406 of the electronics device 200 ;
Installation 407 of the enclosure 26 of the electronics device 200 into the cavity 25 ; optionally the enclosure 26 is installed so that its electrically conductive contacts 26e are facing opposite of and are in electrical contact with the electrical contact terminals of the tripwire 201
Assembly 409 of the first portion 23 and the second potion 24 of the display sign 20 so that the enclosure 26 of the electronics device 200, and preferably the tripwire 201, are placed in between the first portion 23 and the second portion 24;
End 410 of manufacturing of the display sign 20.
According to another embodiment illustrated in figure 12, the manufacturing method may comprise the following steps :
Start of manufacturing 501 ;
Supply the first portion 23 of the display sign 20 to be manufactured ;
Supply the second portion 24 of the display sign 20 to be manufactured ;
Optionally, retrieval of user information 502 provided by the user;
Printing 503 of information on a surface of the first portion 23 of the display sign 20 destined to be the front surface of the display sign 20 ;
Optionally, printing of user information 502 on a surface of the first portion 23 of the display sign 20 in the customisable information areas 22 ;
Machining 504 of a pass-through cut-out 29 destined to accommodate the shell 26a of the electronics device 200 in the second portion 24, preferably in the bulk of the second portion 24 ;
Deposit 505 of an adhesive on a surface of the first portion 23 and/or a surface of the second portion 24 ;
Configuration 506 of the electronics device 200 ;
Installation 507 of the electronics device 200 into the shell 26a ;
Closing 508 of the shell 26a with the front film 27 ;
Installation 509 of the tripwire 201 in between the first portion 23 and the second portion 24 and connection of the tripwire 201 to the electronics device 200 ; Advantageously, the tripwire 201 is laid out randomly in between the first portion 23 and the second portion 24.
Connection 510 of the tripwire 201 with the electronics device 200
Insertion 511 of the shell 26a comprising the electronics device 200 into the passthrough cut-out 29 ;
Assembly 512 of the first portion 23 and the second potion 24 of the display sign 20 so that the enclosure 26 of the electronics device 200, and preferably the tripwire 201, are placed in between the first portion 23 and the second portion 24, the enclosure 26 being formed by the shell 26a and the front film 27 ;
Optionally, laying of a rear film 28 at the level of the exterior surface of the second portion 24 of the display sign 20 bearing the pass-through cut-out 29 so as to close off said pass-through cut-out 29 comprising said shell 26a.
End 512 of manufacturing of the display sign 20.
This manufacturing method thus allows to provide an opening in the rear surface of the display sign 20, said opening covered by a rear film 27, for instance self-adhesive. This opening thus allows the easy and reliable removal of the enclosure 26 comprising the electronics device
200. This solution is advantageous for instance in the case where the user must return the electronics device 200 or for maintenance issues for instance.
Thus, the present invention proposes at least two simple, efficient and quick methods for manufacturing a display sign according to the present invention.
The present invention thus provides a simple and secure solution for establishing an affidavit of the display of a display sign by providing a continuous monitoring of its geographical position, of its orientation, of its displacements if there are any, of its physical integrity and of its visibility. All these data are preferably encrypted and advantageously digitally signed in order to certify their authenticity and invalidate any tampering attempt.
The present invention thus provides a display sign particularly useful for the proof of the display of regulated information requiring a monitoring of the display such as a planning application notice sign.
Cleverly, the geolocation of an item that must stay still during a given time period ensures the collection of proofs and uses in a novel way the usual features of geolocation systems.
The use of a tripwire laid out in the display sign brings an efficient detection ability against any laceration of the front surface of the display sign that may lead to a loss of visibility of the displayed information.
The use of a thin and light enclosure, removable by cutting off the front or rear surface, allows to envision the recycling of the electronics device from one sign to another ; while safeguarding the ability to detect any unauthorised removal by the severance of the electrical contact with the tripwire.
The use of one or several sensors, notably an accelerometer, brings to the present invention an increased ability to detect events likely to disturb the visibility of the displayed information and the compliance of the display.
The use of end-to-end encryption technologies for the data flow brings an additional guarantee with regards to the validity of data and therefore of the generated affidavit.
The field of application of the invention may therefore encompass any field requiring the proof that some information has been displayed in a precise location fora certain duration.
The invention is not limited to the embodiments described herein, but encompasses any embodiment within the scope of the claims.
