Des moyens de temporisation (8) sont prévus pour neutraliser automatiquement le code lorsqu'un temps prédéterminé s'est écoulé à compter d'un instant prédéterminé, ce qui rend dès lors le boîtier inopérant.It is a portable box (2) capable of transmitting, in response to the pressing of a push button (1), a control signal (S) coded according to a code recorded in said box. Timing means (8) are provided for automatically neutralizing the code when a predetermined time has elapsed from a predetermined instant, which therefore makes the housing inoperative.

Description

L'invention est relative aux dispositifs destinés à assurer des commandes, de préférence des ouvertures de portes, à l'aide de signaux codés.The invention relates to devices intended to provide controls, preferably door openings, using coded signals.

Elle vise plus particulièrement, parmi ces dispositifs, ceux qui comportent d'une part un boîtier portatif propre à émettre des signaux codés correspondant à un code préalablement enregistré dans ce boîtier et d'autre part un récepteur monté sur l'organe à commander et agencé de façon à recevoir lesdits signaux codés, à les comparer à une référence préalablement enregistrée et à assurer la commande désirée lorsque cette comparaison révèle une identité entre le signal codé reçu et la référence.It is more particularly aimed, among these devices, at those which comprise on the one hand a portable box suitable for transmitting coded signals corresponding to a code previously recorded in this box and on the other hand a receiver mounted on the member to be controlled and arranged so as to receive said coded signals, to compare them with a previously recorded reference and to provide the desired command when this comparison reveals an identity between the received coded signal and the reference.

Elle concerne plus spécialement les boîtiers émetteurs de ces dispositifs de commande.It relates more specifically to the transmitter boxes of these control devices.

Dans certaines circonstances, le responsable d'un local ou appareillage déterminé, dont l'accès est contrôlé par une serrure elle-même commandable par un dispositif à code du genre ci-dessus, peut être désireux d'autoriser cet accès à un tiers pendant seulement une durée limitée, cette durée dépendant de l'application envisagée et pouvant varier dans une large mesure, étant par exemple d'un quart d'heure pour l'exploitation d'un appareil prédéterminé ou d'une journée pour la disponibilité d'une chambre d'hôtel.In certain circumstances, the person in charge of a specific room or apparatus, access to which is controlled by a lock which can itself be controlled by a code device of the above type, may be eager to authorize this access to a third party for only a limited duration, this duration depending on the application envisaged and which can vary to a large extent, being for example a quarter of an hour for the operation of a predetermined device or a day for the availability of a hotel room.

Avec les modes de réalisation actuels des boîtiers émetteurs du genre en question, le boîtier affecté à la commande de la serrure est confié à chaque usager temporairement autorisé au début de la durée d'autorisation et ce boîtier doit être remis par cet usager au responsable à la fin de cette durée.With the current embodiments of the transmitter boxes of the type in question, the box assigned to the control of the lock is entrusted to each user temporarily authorized at the start of the authorization period and this case must be handed over by this user to the person in charge at the end of this period.

L'inconvénient de la formule réside en ce que la serrure considérée demeure actionnable par le porteur dudit boîtier au-delà de la durée autorisée s'il ne se dessaisit pas de ce boîtier à la fin de cette durée.The drawback of the formula is that the lock considered remains operable by the wearer of said housing beyond the authorized duration if it does not relinquish this housing at the end of this duration.

Cet inconvénient peut être grave dans certains cas.This inconvenience can be serious in some cases.

L'invention a pour but, surtout, de supprimer cet inconvénient.The object of the invention is, above all, to eliminate this drawback.

A cet effet chaque boîtier émetteur du genre en question est essentiellement caractérisé, selon l'invention, en ce qu'il comprend des moyens de temporisation propres à neutraliser automatiquement et définitivement le code qui y est enregistré au terme d'un temps T1 donné écoulé à partir d'un instant t, prédéterminé, instant qui est notamment celui de l'enregistrement de ce code.To this end, each transmitter unit of the type in question is essentially characterized, according to the invention, in that it comprises timing means capable of automatically and definitively neutralizing the code which is recorded therein at the end of a given time T 1 elapsed from a predetermined time t, which is in particular that of the registration of this code.

Dans des modes de réalisation préférés, on a recours en outre à l'une et/ou à l'autre des dispositions suivantes:

  • - en plus du code ci-dessus, "d'ordre 1", au moins un autre code d'ordre i (i étant un entier au moins égal à 2), correspondant à une commande distincte, est enregistré dans le boîtier et chacun de ces autres codes est associé à des moyens de temporisation propres à le neutraliser au terme d'un temps Ti différent de T1 écoulé à partir d'un instant ti prédéterminé, instant de préférence confondu avec l'instant t1,
  • - dans un dispositif de commande selon l'alinéa précédent, les moyens d'élaboration des signaux codés de commande sont tels que chacun des signaux élaborés par ces moyens à un instant donné soit porteur des divers codes valides à cet instant et soit habile à assurer toutes les commandes asservies individuellement à ces divers codes et seulement ces commandes-là,
  • - le boîtier comporte des moyens d'affichage propres à indiquer à chaque instant désiré l'état neutralisé ou non de chaque code enregistré,
  • - le boîtier selon l'alinéa précédent comporte des moyens associés à chaque code enregistré pour indiquer au moins approximativement à chaque instant désiré la durée restante séparant cet instant de l'instant futur de neutralisation dudit code.
In preferred embodiments, use is also made of one and / or the other of the following arrangements:
  • - in addition to the above code, "of order 1", at least one other order code i (i being an integer at least equal to 2), corresponding to a separate command, is recorded in the box and each of these other codes is associated with timing means capable of neutralizing it at the end of a time T i different from T 1 elapsed from a predetermined instant t i , instant preferably confused with instant t 1 ,
  • - In a control device according to the preceding paragraph, the means for developing the coded control signals are such that each of the signals produced by these means at a given time is carrying the various codes valid at this time and is able to provide all the commands slaved individually to these various codes and only these commands,
  • the box includes display means suitable for indicating at any desired instant the neutralized state or not of each recorded code,
  • - The box according to the preceding paragraph comprises means associated with each recorded code to indicate at least approximately at each desired instant the remaining time separating this instant from the future instant of neutralization of said code.

L'invention comprend, mises à part ces dispositions principales, certaines autres dispositions qui s'utilisent de préférence en même temps et dont il sera plus explicitement question ci-après.The invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.

Dans ce qui suit, l'on va décrire des modes de réalisation préférés de l'invention en se référant au dessin ci-annexé d'une manière bien entendu non limitative.In what follows, we will describe preferred embodiments of the invention with reference to the accompanying drawing in a manner of course not limiting.

La figure unique de ce dessin montre schêmatique- ment un dispositif de commande à code établi selon l'invention.The single figure of this drawing schematically shows a code control device established according to the invention.

On se propose d'assurer, par simple appui d'un bouton-poussoir 1 compris par un boîtier portatif de poche 2, une commande électrique codée quelconque telle que, par exemple, le déverrouillage de la serrure d'une porte (non représentée) éventuellement suivi de l'ouverture automatique de cette porte.It is proposed to provide, by simply pressing a push button 1 included in a portable pocket box 2, any coded electrical control such as, for example, unlocking the lock of a door (not shown) possibly followed by the automatic opening of this door.

On fait comprendre à cet effet audit boîtier :

  • - une source de courant électrique 3,
  • - une mémoire 4 propre à enregistrer un code C correspondant aux signaux de commande codés à émettre S,
  • - un circuit électronique 5 relié à ladite mémoire 4 et propre à élaborer lesdits signaux S, lesquels se présentent généralement sous la forme de suites codées d'impulsions électriques,
  • - un organe 6 propre à émettre vers l'extérieur du boîtier 2 les signaux S ainsi élaborés, l'émission en question étant de préférence effectuée par des ondes électromagnétiques ou ultrasonores,
  • - et un dispositif électronique 7 agencé de façon telle que chaque enfoncement, schématisé par la flèche F, du bouton-poussoir 1, provoque la lecture du code enregistré en 4, la transmission du signal codé S correspondant à l'émetteur 6 et donc l'émission de ce signal S.
To this end, it is understood that said box:
  • - a source of electric current 3,
  • a memory 4 capable of recording a code C corresponding to the coded control signals to be transmitted S,
  • an electronic circuit 5 connected to said memory 4 and suitable for producing said signals S, which generally take the form of coded sequences of electrical pulses,
  • a member 6 capable of transmitting the signals S thus produced towards the outside of the housing 2, the transmission in question preferably being carried out by electromagnetic or ultrasonic waves,
  • - And an electronic device 7 arranged in such a way that each depression, shown diagrammatically by the arrow F, of the push button 1, causes the reading of the code recorded in 4, the transmission of the coded signal S corresponding to the transmitter 6 and therefore the emission of this signal S.

La source de courant 3 peut être une pile ou l'un des composants d'un transformateur dont un autre composant serait une boucle entourant l'emplacement où le boîtier 2 doit se trouver pour assurer l'émission des signaux S.The current source 3 may be a battery or one of the components of a transformer of which another component would be a loop surrounding the location where the box 2 must be located to ensure the emission of the signals S.

De son côté la serrure à commander est associée à un récepteur comportant des moyens propres à recevoir les signaux S et à les transformer en signaux exploitables élec- troniquement, une mémoire dans laquelle a été enregistré un code de référence R, des moyens pour comparer au code R le code C porté par chaque signal reçu S et des moyens pour émettre un signal électrique de commande E chaque fois qu'il y a identité entre les deux codes C et R, et ladite serrure est elle-même agencée de façon à pouvoir être actionnée par ledit signal de commande E.For its part, the lock to be controlled is associated with a receiver comprising means suitable for receiving the signals S and for transforming them into electrically exploitable signals, a memory in which a reference code R has been recorded, means for comparing with the code R the code C carried by each received signal S and means for transmitting an electrical control signal E each time there is identity between the two codes C and R, and said lock is itself arranged so as to be able to be actuated by said control signal E.

Avec un tel ensemble, lorsque le code C correct, c'est-à-dire correspondant au code R enregistré dans le récepteur, a été enregistré dans la mémoire 4 du boîtier 2, il suffit d'appuyer sur le bouton 1 pour assurer l'émission d'un signal codé S, et donc pour déverrouiller la serrure si le boîtier est situé suffisamment près de celle-ci et orienté de manière adéquate.With such an assembly, when the correct code C, that is to say corresponding to the code R recorded in the receiver, has been recorded in the memory 4 of the housing 2, it suffices to press the button 1 to ensure the 'emission of a coded signal S, and therefore to unlock the lock if the housing is located close enough to it and oriented properly.

Une telle commande codée demeure possible tant que le circuit électronique 5 est en mesure d'élaborer des signaux codés S et que la serrure à déverrouiller est en mesu- .― re de recevoir ces signaux, de les identifier et de les exploiter.Such coded control remains possible as long as the electronic circuit 5 is able to develop coded signals S and the lock to be unlocked is able to receive these signals, to identify them and to use them.

L'objet essentiel de l'invention consiste à mettre automatiquement un terme à cette possibilité de commande à la fin d'une période d'autorisation ou de validation de durée prédéterminée T1 afin de rendre impossibles les commandes codées en question par le porteur du boîtier 2 considéré au-delà de ladite période.The essential object of the invention is to automatically put an end to this possibility of ordering at the end of an authorization or validation period of predetermined duration T 1 in order to make impossible the coded orders in question by the carrier of the box 2 considered beyond said period.

A cet effet, on incorpore au boîtier 2 des moyens de temporisation propres à neutraliser automatiquement le code C en question à la fin de la période considérée, laquelle commence à un instant t, prédéterminé.To this end, the housing 2 incorporates timing means capable of automatically neutralizing the code C in question at the end of the period considered, the which begins at a predetermined time t.

Cet instant t1 est de préférence celui de l'enregistrement dudit code dans la mémoire 4, lequel instant coïncide généralement avec celui auquel le boîtier est confié à l'usager autorisé.This instant t 1 is preferably that of the recording of said code in the memory 4, which instant generally coincides with that at which the box is entrusted to the authorized user.

Mais l'instant t1 en question auquel débute la période de validité du boîtier 2 pourrait également être postérieur d'une autre durée prédéterminée Ti à l'instant de l'enregistrement du code dans la mémoire.But the instant t 1 in question at which the period of validity of the box 2 begins could also be later than another predetermined duration Ti at the time of the recording of the code in the memory.

Les moyens de temporisation en question ont été schématisés sur le dessin par le bloc 8 alimenté à partir de la source 3 et propre à attaquer (flèche g) la mémoire 4 aux fins de neutralisation de cette mémoire.The timing means in question have been shown diagrammatically in the drawing by the block 8 supplied from the source 3 and suitable for attacking (arrow g) the memory 4 for the purpose of neutralizing this memory.

Cette neutralisation est assurée notamment par effacement du code C enregistré dans la mémoire, ou par rupture de la liaison (flèche h) par laquelle cette mémoire instruit le circuit d'élaboration 5.This neutralization is ensured in particular by erasing the code C recorded in the memory, or by breaking the link (arrow h) by which this memory instructs the processing circuit 5.

Dès lors, après expiration du temps T1, le boîtier 2 ne peut plus émettre de signaux codés S et son porteur ne peut plus déverrouiller la serrure asservie à ces signaux.Consequently, after the time T 1 has expired, the box 2 can no longer transmit coded signals S and its carrier can no longer unlock the lock controlled by these signals.

Ledit boîtier est donc devenu inopérant.Said housing has therefore become inoperative.

Dès la remise de ce boîtier au responsable de la serrure à surveiller, le code approprié C peut à nouveau être enregistré à tout instant désirable dans la mémoire 4 de ce boîtier, ce qui le rend à nouveau apte au déverrouillage de ladite serrure pendant la durée T1 ci-dessus à compter d'un nouvel instant tl.As soon as this box is handed over to the person responsible for the lock to be monitored, the appropriate code C can again be recorded at any desirable time in the memory 4 of this box, which again makes it suitable for unlocking said lock for the duration T 1 above from a new instant t l .

De nombreux perfectionnements peuvent être apportés au boîtier ci-dessus et en particulier les suivants.Many improvements can be made to the above case and in particular the following.

En premier lieu, il peut être précieux pour l'usager du boîtier 2 de savoir à chaque instant si celui-ci est encore valide ou, mieux encore, combien de temps sépare ledit instant de la fin de la période de validité.Firstly, it can be precious for the user of the box 2 to know at each instant whether it is still valid or, better still, how long separates said instant from the end of the period of validity.

La première information peut être très simplement obtenue par affichage sur le boîtier d'un signal de validité de type tout ou rien, tel que l'allumage d'un voyant lumineux 9 ou que l'apparition d'un signe contrasté sur un fond neutre, réalisé à l'aide de cristaux liquides.The first information can be very simply obtained by displaying on the box an all-or-nothing validity signal, such as the lighting of an indicator light 9 or the appearance of a contrasting sign on a background. neutral, produced using liquid crystals.

Pour économiser l'énergie de la source 8, cet affichage peut être assuré uniquement en réponse à l'appui d'un bouton-poussoir de vérification 10 associé à un interrupteur approprié 11.To save the energy of the source 8, this display can be ensured only in response to the pressing of a verification push button 10 associated with an appropriate switch 11.

La seconde information peut être donnée par affichage sur le boîtier d'un signal de validité évolutif, c'est-à-dire propre à évoluer du début à la fin de la période de validité, de préférence progressivement.The second information can be given by displaying on the unit an evolving validity signal, that is to say capable of changing from the start to the end of the validity period, preferably progressively.

Un tel signal évolutif peut être constitué par exemple par une suite de points contrastés engendrés par des cristaux liquides sur un fond neutre, points dont les effacements se succèdent de proche en proche dans le temps, ou encore par un affichage numérique.Such an evolving signal can be constituted for example by a series of contrasting points generated by liquid crystals on a neutral background, points the erasures of which follow one another step by step over time, or even by a digital display.

Selon un autre perfectionnement permettant d'affecter des durées de validation différentes au boîtier 2 en fonction de différentes serrures à commander au nombre de n (n étant un entier supérieur à 1 et notamment égal à 2), le nombre des codes enregistrés dans la mémoire 4 du boîtier 2 et propres à instruire le circuit électronique 5 est égal à n, ces codes Ci (i étant un entier compris entre 1 et n) sont enregistrés simultanément dans la mémoire 4, leurs durées de validité respectives Ti sont différentes et débutent à des instants ti qui peuvent être eux-mêmes différents mais sont de préférence confondus.According to another improvement making it possible to assign different validation durations to the housing 2 as a function of different locks to be controlled by the number of n (n being an integer greater than 1 and in particular equal to 2), the number of codes stored in the memory 4 of the housing 2 and suitable for instructing the electronic circuit 5 is equal to n, these codes Ci (i being an integer between 1 and n) are recorded simultaneously in the memory 4, their respective validity periods T i are different and begin at times t i which may themselves be different but are preferably combined.

Sur le dessin, la flèche g' symbolise les neutralisations des divers codes Ci d'ordre i supérieur à 1 au terme des divers retards Ti déterminés par le circuit -8 et la flèche h' symbolise l'instruction du circuit d'élaboration 5 par ces divers codes, enregistrés dans la mémoire 4.In the drawing, the arrow g 'symbolizes the neutralizations of the various codes C i of order i greater than 1 at the end of the various delays T i determined by the circuit -8 and the arrow h' symbolizes the instruction of the processing circuit 5 by these various codes, stored in memory 4.

Un tel enregistrement multiple de codes peut être exploité de plusieurs façons.Such multiple code registration can be exploited in several ways.

C'est ainsi que l'on peut avoir recours à respectivement n voies parallèles d'élaboration de signaux codés distincts Si d'ordre i codés respectivement selon les codes Ci, voies exploitables simultanément par les appuis du bouton 1, chaque signal Si d'ordre i étant propre à commander les serrures asservies sélectivement au code Ci de même ordre que ce signal.This is how recourse can be had respectively to n parallel paths for developing separate coded signals S i of order i coded respectively according to the codes C i , channels which can be used simultaneously by pressing the bou tone 1, each signal Si of order i being suitable for controlling the locks selectively slaved to the code Ci of the same order as this signal.

Si donc à un instant donné le nombre des codes valides est égal à j (j étant un entier compris entre 1 et n), chaque appui sur le bouton 1 se traduit par l'émission d'un faisceau de j signaux Si et la serrure réceptrice de tous ces signaux est effectivement déverrouillée si, et seulement si, le code qui lui est associé fait partie des j codes valides à l'instant considéré.If therefore at a given time the number of valid codes is equal to j (j being an integer between 1 and n), each press on button 1 results in the emission of a beam of j signals Si and the lock receiving all of these signals is effectively unlocked if, and only if, the code associated with it is one of the j codes valid at the instant considered.

Selon une autre formule, l'enregistrement multiple en question se traduit par l'émission, pour chaque appui sur le bouton 1,_ de signaux uniques codés j fois, j variant de 0 à n selon l'instant dudit appui, signaux propres à déverrouiller chacun des serrures de types différents, chaque serrure de type i étant sensible à ceux, desdits signaux, qui sont codés n+l-i fois ou plus.According to another formula, the multiple recording in question results in the emission, for each press of the button 1, _ of single signals coded j times, j varying from 0 to n according to the instant of said press, signals specific to unlock each of the locks of different types, each type i lock being sensitive to those of said signals, which are coded n + li times or more.

Dans ces conditions, si les durées Ti croissent lorsque l'indice i croît de 1 à n,

  • - les serrures d'ordre 1 ne sont déverrouillables que par les signaux codés au maximum, c'est-à-dire n fois et elles cessent d'être déverrouillables à la fin de la durée T1 la plus courte,
  • - les serrures d'ordre 2 sont déverrouillables par les signaux codés n ou n-1 fois et cessent d'être déverrouillables à la fin de la durée T2,
  • - et ainsi de suite, les serrures d'ordre n étant déverrouillables le plus longtemps, savoir par tous les signaux précédents et étant les seuls à pouvoir l'être encore par ceux codés par le seul dernier code d'ordre n.
Under these conditions, if the durations T i increase when the index i increases from 1 to n,
  • - the locks of order 1 are unlockable only by the signals coded to the maximum, that is to say n times and they cease to be unlockable at the end of the shortest duration T 1 ,
  • - the locks of order 2 are unlockable by the signals coded n or n-1 times and cease to be unlockable at the end of the duration T 2 ,
  • - And so on, the locks of order n being unlockable the longest, namely by all the preceding signals and being the only ones able to be unlocked by those coded by the only last code of order n.

Le boîtier 2 peut être agencé de façon telle que chaque enfoncement du bouton-poussoir 1 assure l'émission d'un seul signal codé S.The housing 2 can be arranged in such a way that each depression of the push button 1 ensures the emission of a single coded signal S.

Il peut également être agencé de façon telle que cette émission soit renouvelée systématiquement, par exemple une fois par seconde, tant que le bouton-poussoir demeure enfoncé.It can also be arranged in such a way that this emission is systematically renewed, for example once per second, as long as the push button remains pressed.

Les différentes données relatives aux codes, aux durées de validité de ces codes et éventuellement aux instants de prise d'effet de ces validités, si ces instants diffèrent des instants de remise des boîtiers aux porteurs autorisés, peuvent être enregistrées en permanence dans ces boîtiers, et dans ce cas le responsable desdits boîtiers doit seulement réactiver ces données lors des différentes remises des boîtiers à leurs porteurs.The various data relating to the codes, to the periods of validity of these codes and possibly to the instants of taking effect of these validities, if these instants differ from the instants of delivery of the boxes to authorized carriers, can be permanently recorded in these boxes, and in this case the person responsible for said boxes must only reactivate this data when the boxes are delivered to their carriers.

Selon une variante, les données en question ne sont pas enregistrées en permanence dans les boîtiers et y sont introduites par le responsable à l'aide d'un programmateur.According to a variant, the data in question are not permanently saved in the boxes and are introduced there by the person in charge using a programmer.

Lesdites données peuvent avoir été elles-mêmes préalablement enregistrées, au moins en partie, dans ledit programmateur, ou bien elles peuvent être directement composées sur ce programmateur à l'aide d'un clavier ou de toute autre manière désirable.Said data may themselves have been previously recorded, at least in part, in said programmer, or they may be directly composed on this programmer using a keyboard or in any other desirable manner.

Dans le cas de l'enregistrement préalable dans le programmateur, il peut être opportun de protéger ce dernier vis-à-vis des usages non autorisés.In the case of prior registration in the programmer, it may be advisable to protect the latter against unauthorized uses.

A cet effet., on agence le programmateur de façon telle que chacune de ses mises en oeuvre exige la composition préalable d'un code secret ou encore l'utilisation d'une clé spéciale codée de toute manière désirable.To this end, the programmer is arranged in such a way that each of its implementations requires the prior composition of a secret code or even the use of a special key coded in any desirable manner.

Des moyens inviolables par l'usager peuvent être prévus pour modifier le début et/ou la fin de chaque période de validation enregistrée dans le boîtier.Means inviolable by the user can be provided to modify the start and / or the end of each validation period recorded in the box.

On peut également agencer ce boîtier de façon telle qu'il se prête à la lecture des diverses informations qui y sont enregistrées, et ce à l'aide d'un appareil de lecture spécialement prévu à cet effet et disponible seulement du responsable des boîtiers.This box can also be arranged in such a way that it is suitable for reading the various information recorded therein, and this using a reading device specially designed for this purpose and available only from the person responsible for the boxes.

Cette lecture permet audit responsable de faire le point sur les habilitations respectives des divers boîtiers, soit individuellement lors de la présentation de chaque boîtier, soit globalement après rassemblement de l'ensemble des boîtiers distribués.This reading allows the responsible manager to take stock of the respective authorizations of the various boxes, either individually during the presentation of each box, or globally after assembly of the set ble of distributed boxes.

Pour compléter l'information du responsable, on peut affecter à chaque code une marque spéciale permettant d'identifier le porteur du boîtier recevant ce code.To supplement the information of the person responsible, a special mark can be assigned to each code making it possible to identify the wearer of the box receiving this code.

Chaque boîtier peut également être agencé de façon à affecter à chaque signal codé émis par lui une marque spéciale d'identification de ce boîtier, marque susceptible d'être exploitée à des fins d'enregistrement et/ou d'affichage par les serrures alors spécialement aménagées en conséquence et/ou par l'appareil de lecture mentionné ci-dessus.Each box can also be arranged so as to assign to each coded signal emitted by it a special mark identifying this box, a mark which can be used for recording and / or display purposes by the locks then specially arranged accordingly and / or by the above-mentioned reading device.

Chaque boîtier peut être agencé de façon telle que chaque code enregistré dans sa mémoire soit facilement neutralisable par une intervention extérieure volontaire, même avant expiration de la durée de validation correspondante. Cette intervention extérieure peut être l'appui d'un bouton-poussoir prévu à cet effet, ou encore l'arrachement d'une pièce propre à couper une liaison électrique.Each box can be arranged in such a way that each code recorded in its memory can be easily neutralized by voluntary external intervention, even before the expiration of the corresponding validation period. This external intervention can be the pressing of a push button provided for this purpose, or even the tearing of a clean part to cut an electrical connection.

En suite de quoi, et quel que soit le mode de réalisation adopté, on obtient finalement un dispositif de commande codé dont la constitution, le fonctionnement et les avantages résultent suffisamment de ce qui précède.As a result of which, and whatever the embodiment adopted, there is finally obtained a coded control device whose constitution, operation and advantages result sufficiently from the above.

Comme il va de soi, et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réalisation qui ont été plus spécialement envisagés ; elle en embrasse, au contraire, toutes les variantes.As is obvious, and as already follows from the foregoing, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; on the contrary, it embraces all its variants.
