En outre, la désolidarisation des antennes de l'appareil électronique est favorable à la réception en ce que le positionnement libre des antennes permet de trouver plus facilement une position où le signal est le mieux capté.

Solution selon l'invention:Solution according to the invention

Les solutions à l'état de l'art n'apportent qu'une réponse partielle et insatisfaisante au problème de la réception et/ou de l'émission des signaux radiofréquences à l'aide de moyens autonomes et compacts utilisables en mobilité.
Selon un premier aspect de l'invention, il est proposé un dispositif selon la revendication 1.
Le dispositif selon l'invention permet à un appareil électronique portable de recevoir et /ou d'émettre des signaux radiofréquences. Le dispositif comprend au moins un sous-ensemble électronique, des moyens pour connecter l'au moins un sous-ensemble électronique du dispositif à l'appareil électronique, au moins deux antennes exploitées en diversité, inamovibles et rendues solidaires du dispositif par la mise en oeuvre de moyens conservant les positions relatives des dites antennes et du dispositif en l'absence de l'application de forces extérieures entre ces éléments. Ce dispositif peut être un accessoire dédié à un type ou à un modèle d'appareil électronique portable ou encore il peut s'agir d'un accessoire universel pouvant être utilisé en périphérie d'appareils électroniques divers.
On entend par au moins un sous ensemble électronique, un ou plusieurs blocs fonctionnels pouvant être mis en oeuvre sous la forme d'un ou de plusieurs circuits imprimés. Il s'agit par exemple d'assurer dans un ordre pouvant être différent, tout ou partie des fonctions de la liste non limitative suivante : amplification du signal provenant des antennes, combinaison des signaux, démodulation, de gestion de la diversité, décodage, de gestion de l'interface avec l'appareil portable.The state-of-the-art solutions provide only a partial and unsatisfactory response to the problem of receiving and / or transmitting radio frequency signals using autonomous and compact means that can be used in mobility.
According to a first aspect of the invention, there is provided a device according to claim 1.
The device according to the invention allows a portable electronic device to receive and / or transmit radio frequency signals. The device comprises at least one electronic subassembly, means for connecting the at least one electronic subassembly of the device to the electronic device, at least two antennas exploited in diversity, irremovable and made integral with the device by the implementation. implement means retaining the relative positions of said antennas and the device in the absence of the application of external forces between these elements. This device can be an accessory dedicated to a type or model of portable electronic device or it can be a universal accessory that can be used on the periphery of various electronic devices.
At least one electronic subassembly means one or more functional blocks that can be implemented in the form of one or more printed circuits. This is for example to ensure in a different order, all or part of the functions of the following nonlimiting list: amplification of the signal from the antennas, combination of signals, demodulation, diversity management, decoding, management of the interface with the portable device.

On entend par, au moins deux antennes exploitées en diversité, toute mise en oeuvre d'au moins une technique de diversité visant à accroitre les performances d'un système de transmission numérique sans fil.At least two antennas exploited in diversity are understood to mean any implementation of at least one diversity technique aimed at increasing the performance of a digital wireless transmission system.

L'accroissement de performance qu'apporte la diversité d'antenne est particulièrement avantageux par exemple pour recevoir la télévision et/ou la radio numérique en mobilité dans de bonnes conditions. Ceci en particulier si la diversité d'antenne est complétée par un canal de réception dédié par antenne avec des traitements appropriés des signaux. Lorsqu'il s'agit d'apporter à l'appareil électronique portable une connectivité à des réseaux au moyen du dispositif selon l'invention, la diversité d'antenne peut également être exploitée aussi en émission, par exemple dans le cadre de solutions de type MIMO telles que mises en oeuvre dans le standard 802.11n de l'IEEE. La diversité d'antenne peut impliquer un nombre illimité d'antennes, seules des contraintes économiques, d'encombrement et/ou d'esthétique poussent à limiter ce nombre, le plus souvent à deux voire trois antennes. La mise en oeuvre de l'invention peut ne porter que sur la diversité d'emplacement d'antennes identiques mais il peut s'agir également de diversité de polarisation, de diversité de type d'antenne et plus généralement de la mise en oeuvre de toute solution permettant d'augmenter la probabilité qu'au moins une antenne se trouve à un instant donné dans des conditions de fonctionnement satisfaisantes. On reste cependant dans le cadre de l'invention en mettant en oeuvre des techniques dites de micro diversité, c'est-à-dire lorsque la distance entre les antennes est de l'ordre de la longueur d'onde utilisée.The increase in performance provided by antenna diversity is particularly advantageous for example to receive television and / or digital radio mobility in good conditions. This is particularly true if the antenna diversity is supplemented by a dedicated antenna receiving channel with appropriate signal processing. When it comes to providing the portable electronic device with connectivity to networks by means of the device according to the invention, the antenna diversity can also be exploited also in transmission, for example in the context of MIMO type as implemented in the 802.11n standard of the IEEE. Antenna diversity can involve an unlimited number of antennas, only economic constraints, clutter and / or aesthetics push to limit this number, usually two or three antennas. The implementation of the invention may relate only to the diversity of locations of identical antennas, but it may also be diversity of polarization, diversity of antenna type and more generally of the implementation of any solution to increase the probability that at least one antenna will be at a given moment under satisfactory operating conditions. However, we remain within the scope of the invention by implementing so-called micro diversity techniques, that is to say when the distance between the antennas is of the order of the wavelength used.

Dans certains modes de mise en oeuvre de l'invention, il est prévu que le dispositif comprenne en outre au moins une liaison mécanique rigide amovible pour fixer le dispositif à l'appareil électronique portable.
L'au moins une liaison mécanique rigide amovible peut avantageusement inclure des contacts pour connecter l'au moins un sous-ensemble électronique du dispositif à l'appareil électronique portable auquel il est fixé. Il peut s'agir par exemple d'un connecteur spécifique ou encore d'un connecteur standard suffisamment robuste par exemple un connecteur USB de type A.
Il est prévu que la connexion entre le dispositif et l'appareil puisse se faire par une liaison mécanique rigide amovible incluant des contacts que complète au moins une autre liaison mécanique rigide amovible sans contact pour renforcer la robustesse mécanique de l'assemblage.
Il est également prévu que la connexion entre le dispositif et l'appareil puisse utiliser des moyens filaires, tels qu'au moins un câble équipé d'au moins un connecteur, ou encore par des moyens sans fil, par exemple reposant sur l'utilisation des standards Bluetooth, WUSB ou Wifi ad' hoc.In certain embodiments of the invention, it is provided that the device further comprises at least one removable rigid mechanical connection for fixing the device to the portable electronic device.
The at least one removable rigid mechanical connection may advantageously include contacts for connecting the at least one electronic subassembly of the device to the portable electronic device to which it is attached. It may be for example a specific connector or a sufficiently robust standard connector for example a type A USB connector.
It is envisaged that the connection between the device and the device can be done by a removable rigid mechanical connection including contacts that complete at least one other non-contact removable rigid mechanical connection to reinforce the mechanical robustness of the assembly.
It is also expected that the connection between the device and the device can use wire means, such as at least one cable equipped with at least one connector, or by wireless means, for example based on the use standards Bluetooth, WUSB or Wifi ad 'hoc.

On entend par, au moins deux antennes inamovibles et rendues solidaires du dispositif par la mise en oeuvre de moyens conservant les positions relatives des dites antennes et du dispositif en l'absence de l'application de forces extérieures entre ces éléments, le fait que le dispositif selon l'invention mette en oeuvre des solutions de fixation non démontables des antennes sur le corps du dispositif. Dans le cas où au moins un degré de liberté est mis en oeuvre alors il est prévu des forces de friction pour conserver les positions relatives des éléments les uns par rapport aux autres tant qu'aucune autre force d'intensité supérieure n'est appliquée. Le but est que toute modification du positionnement d'un élément du système relativement aux autres, lorsqu'elle est possible, est conservée tant qu'aucune autre action ne la remet en cause. Ce but peut être atteint par exemple en liant les éléments du système selon l'invention par des moyens rigides, semi-rigides ou flexibles pour conserver les positions relatives à partir d'une position donnée. Des degrés de libertés peuvent être avantageusement introduits dans les assemblages pour à la fois faciliter le rangement de l'accessoire et permettre une optimisation des réglages d'orientation.
En outre, l'utilisation d'éléments flexibles et/ou articulés rend moins fragile l'accessoire et/ou le système qu'il constitue avec l'appareil électronique auquel il est connecté. En effet, les systèmes constitués d'éléments déformables sont moins fragiles en ce qu'ils peuvent subir l'effet de forces externes sans dégâts irréversibles.The term "at least two irremovable antennas" made integral with the device by the implementation of means retaining the relative positions of said antennas and the device in the absence of the application of external forces between these elements, the fact that the device according to the invention implements solutions for fixing non-removable antennas on the body of the device. In the case where at least one degree of freedom is implemented then frictional forces are provided to maintain the relative positions of the elements relative to each other as long as no other higher intensity force is applied. The goal is that any change in the positioning of one element of the system relative to the others, where possible, is retained as long as no other action calls it into question. This object can be achieved for example by linking the elements of the system according to the invention by rigid, semi-rigid or flexible means for maintaining the relative positions from a given position. Degrees of freedom can be advantageously introduced into the assemblies to both facilitate the storage of the accessory and allow optimization of the orientation settings.
In addition, the use of flexible and / or articulated elements makes the accessory and / or the system that it constitutes with the electronic device to which it is connected less fragile. Indeed, systems consisting of deformable elements are less fragile in that they can undergo the effect of external forces without irreversible damage.

Le dispositif selon l'invention prévoit en outre qu'au moins une antenne inamovible du dispositif est agencée pour améliorer ses performances par la présence d'un plan de masse et/ou d'un élément conducteur raccordé à la masse à proximité. On entend par plan de masse toute surface conductrice pleine ou ajourée, raccordée ou non à un potentiel déterminé tel que la masse de l'électronique de réception et/ou d'émission associée. Un plan de masse selon l'invention peut, selon le contexte de mise en oeuvre, jouer par exemple le rôle de l'autre demi-dipôle dans le cas d'une antenne dite demi-dipôle (antenne « fouet »), de réflecteur (antenne « quad »), d'armature relativement à un diélectrique (antenne « patch »), de blindage vis-à-vis de rayonnements indésirables.The device according to the invention further provides that at least one irremovable antenna of the device is arranged to improve its performance by the presence of a ground plane and / or a conductive element connected to ground nearby. Ground plane means any conductive surface full or perforated, connected or not to a specific potential such as the mass of the associated reception and / or transmission electronics. According to the implementation context, a ground plane according to the invention can play, for example, the role of the other half-dipole in the case of a so-called half-dipole antenna (whip antenna), reflector (antenna "quad"), armature relative to a dielectric (antenna "patch"), shielding vis-à-vis undesirable radiation.

L'invention prévoit en outre que ledit plan de masse et/ou l'élément conducteur est déployable. Le déploiement du plan de masse et/ou l'élément conducteur peut être une conséquence de celui d'une antenne. Le déploiement du plan de masse et/ou l'élément conducteur peut aussi être traité en tout ou partie de manière séparée de celui de l'antenne sans sortir du cadre de l'invention.The invention further provides that said ground plane and / or the conductive element is deployable. The deployment of the ground plane and / or the conductive element may be a consequence of that of an antenna. Deployment of the ground plane and / or the conductive element may also be treated in whole or in part separately from that of the antenna without departing from the scope of the invention.

Dans un premier mode de mise en oeuvre de l'invention, au moins une antenne inamovible du dispositif est du type filaire dipolaire ou mono polaire, par exemple un fouet fonctionnant en quart d'onde ou en demi-onde.In a first embodiment of the invention, at least one irremovable antenna of the device is of the dipole or monopole wired type, for example a whip operating in quarter wave or half wave.

Dans un second mode de mise en oeuvre, au moins une antenne inamovible du dispositif est du type boucle magnétique.In a second mode of implementation, at least one irremovable antenna of the device is of the magnetic loop type.

Dans un troisième mode de mise en oeuvre, au moins une antenne inamovible du dispositif est du type planaire.In a third mode of implementation, at least one irremovable antenna of the device is of the planar type.

Pour chacun de ces trois modes de mise en oeuvre, l'au moins autre antenne pouvant être du même type ou d'un type différent.For each of these three modes of implementation, the at least one other antenna can be of the same type or of a different type.

On entend par antenne planaire une antenne constituée d'une pluralité d'éléments surfaciques individuels qui sont agencés dans l'air ou sur un diélectrique solide approprié dans un même plan pour former une antenne composite, par exemple une antenne dite « quad » ou encore une antenne dite « patch » en langue Anglaise. Ces antennes requièrent en outre respectivement un réflecteur métallique et un plan de masse.Planar antenna means an antenna consisting of a plurality of individual surface elements which are arranged in the air or on a suitable solid dielectric in the same plane to form a composite antenna, for example an antenna called "quad" or an antenna called "patch" in English language. These antennas furthermore require respectively a metal reflector and a ground plane.

Dans tous les types d'antennes cités, les éléments filaires ou surfaciques peuvent mettre en oeuvre des géométries simples ou des géométries complexes telles que les solutions dites à remplissage d'espace, sans sortir du cadre de l'invention. Les solutions dites à remplissage d'espace telles que celles reposant sur les mathématiques fractales proposées par la société Fractus SA, permettent d'obtenir, toutes choses égales par ailleurs, en particulier pour des longueurs d'ondes égales, des dimensions plus compactes qu'avec des géométries traditionnelles.In all the types of antennas mentioned, the wired or surface elements can implement simple geometries or complex geometries such as so-called space-filling solutions, without departing from the scope of the invention. Space filling solutions such as those based on fractal mathematics proposed by the company Fractus SA, make it possible to obtain, all things being equal, in particular for equal wavelengths, more compact dimensions than with traditional geometries.

Dans un mode préféré de mise en oeuvre de l'invention, au moins une antenne inamovible du dispositif est déployable.
On entend par déployable toute solution permettant de différencier un état du système selon l'invention moins encombrant pour le transport ou le rangement d'un état plus encombrant en utilisation. Il peut s'agir par exemple de solutions à base d'éléments pliables et/ou télescopiques et/ou enroulables ou encore de toute combinaison de telles solutions. Le déploiement peut mettre en oeuvre tout type de mouvement relatif entre les éléments constitutifs de l'antenne et/ou de l'antenne dans son ensemble relativement au corps de l'accessoire selon l'invention. Il peut s'agir de mouvements de translation et/ou de rotation ou de toute combinaison de ces mouvements élémentaires.
Il est prévu que chaque antenne puisse faire appel à des solutions de déploiement différentes.
Dans cette variante préférée de l'invention, le dispositif comprend une pluralité d'antennes déployables pour le rendre plus compact en position de rangement, pour lui donner une capacité d'adaptation aux dimensions de l'appareil électronique portable auquel il peut être fixé pour former un ensemble monobloc et/ou lui donner une capacité d'orientation des antennes pour optimiser le fonctionnement dans une orientation donnée de l'appareil électronique portable.In a preferred embodiment of the invention, at least one irremovable antenna of the device is deployable.
Deployable means any solution for differentiating a state of the system according to the invention less cumbersome for transport or storage of a more bulky state in use. It may be for example solutions based on folding elements and / or telescopic and / or rollable or any combination of such solutions. The deployment can implement any type of relative movement between the constituent elements of the antenna and / or the antenna as a whole relative to the body of the accessory according to the invention. It can be translational movements and / or rotation or any combination of these elementary movements.
It is expected that each antenna can use different deployment solutions.
In this preferred embodiment of the invention, the device comprises a plurality of deployable antennas to make it more compact in the storage position, to give it a capacity to adapt to the dimensions of the portable electronic device to which it can be fixed to forming a one-piece assembly and / or giving it an antenna orientation capability to optimize operation in a given orientation of the portable electronic device.

L'invention prévoie qu'au moins une antenne parmi au moins deux puisse être fixe relativement au corps de l'accessoire selon l'invention. Plus les longueurs d'ondes utilisées sont courtes, moins il devient nécessaire de rendre les antennes déployables car leur encombrement est faible. Tout ou partie des antennes peuvent même être intégrées dans le corps du dispositif sans pour autant sortir du cadre de l'invention.The invention provides that at least one of at least two antennas can be fixed relative to the body of the accessory according to the invention. More the wavelengths used are short, the less it becomes necessary to make the antennas deployable because their footprint is low. All or part of the antennas can even be integrated into the body of the device without departing from the scope of the invention.

Il est connu que les performances des antennes fixes sont améliorées lorsque leur partie rayonnante est située à un endroit en relation avec un plan de masse ou un élément métallique, raccordé ou non à la masse selon les options techniques de mise en oeuvre. Les antennes déployables à l'état de l'art n'exploitent pas cette possibilité d'amélioration de leurs performances.
Il est prévu dans l'invention qu'au moins une antenne inamovible et déployable voit ses performances améliorées, par exemple son gain, par la présence d'un plan de masse et/ou d'un élément conducteur raccordé à la masse à proximité. Dans un mode préféré de mise en oeuvre, l'au moins une antenne inamovible et déployable comprend à la fois une partie rayonnante et une partie raccordée à la masse.It is known that the performance of fixed antennas are improved when their radiating part is located at a location in relation to a ground plane or a metallic element, connected or not to the ground according to the technical implementation options. Deployable antennas in the state of the art do not exploit this possibility of improving their performance.
It is provided in the invention that at least one irremovable and irremovable antenna sees its improved performance, for example its gain, by the presence of a ground plane and / or a conductive element connected to ground nearby. In a preferred embodiment, the at least one irremovable and deployable antenna comprises both a radiating portion and a grounded portion.

Avantageusement, la partie de l'au moins une antenne inamovible et déployable du dispositif, connecté au potentiel de la masse, est située entre la partie rayonnante de l'antenne et son point d'attache situé sur le corps du dispositif.Advantageously, the portion of the at least one immovable and deployable antenna of the device, connected to the potential of the mass, is located between the radiating part of the antenna and its point of attachment located on the body of the device.

Il est en outre prévu que la partie connectée au potentiel de la masse de l'au moins une antenne inamovible et déployable du dispositif, comprend des éléments conducteurs pour d'une part alimenter la partie rayonnante de l'antenne et d'autre part pour blinder cette ligne d'alimentation.It is further provided that the portion connected to the ground potential of the at least one immovable and deployable antenna of the device comprises conductive elements for firstly supplying the radiating part of the antenna and secondly for shield this power line.

Dans un mode de mise en oeuvre encore plus avantageux de l'invention, les conducteurs pour établir la continuité électrique entre l'antenne déployable et l'électronique de réception forment une liaison dont l'impédance est sensiblement adaptée lorsque l'antenne est complètement déployée. En effet il est difficile et coûteux de mettre en oeuvre une solution permettant d'établir une liaison déployable et continûment adaptée quel que soit l'ampleur du déploiement. En pratique les positions intermédiaires du déploiement ont peu d'intérêt et les performances sont généralement maximales au maximum du déploiement, lorsque les antennes sont les plus éloignées les unes des autres et des sources de bruit que sont les sous-ensembles électronique des appareils numériques.In an even more advantageous embodiment of the invention, the conductors for establishing the electrical continuity between the deployable antenna and the reception electronics form a connection whose impedance is substantially adapted when the antenna is fully deployed. . Indeed it is difficult and expensive to implement a solution to establish a deployable link and continuously adapted whatever the scale of the deployment. In practice, the intermediate positions of the deployment are of little interest and the performances are generally maximum at the maximum of the deployment, when the antennas are furthest away from each other and sources of noise that are the electronic subassemblies of the digital devices.

Dans un premier mode de mise en oeuvre relativement à l'alimentation électrique des sous-ensembles électroniques, le dispositif selon l'invention est alimenté par l'appareil électronique portable auquel il est connecté.In a first embodiment with respect to the power supply of the electronic subassemblies, the device according to the invention is powered by the portable electronic device to which it is connected.

Dans un second mode de mise en oeuvre, c'est le dispositif selon l'invention qui alimente appareil électronique portable auquel il est connecté. Cela peut se faire au moyen d'une source d'énergie contenue dans le dispositif et/ou au moyen d'une source d'énergie externe telle que par exemple un bloc d'alimentation secteur dans le cas d'une utilisation dans un bâtiment ou encore d'une alimentation équipée d'une prise se connectant en lieu et place de l'allume cigare dans le cas d'une utilisation dans un véhicule.In a second mode of implementation, it is the device according to the invention that powers the portable electronic device to which it is connected. This can be done by means of a power source contained in the device and / or by means of an external power source such as for example an AC power supply unit in the case of use in a building or a power supply equipped with a plug connecting instead of the cigarette lighter in the case of use in a vehicle.

Il est prévu dans l'invention que le dispositif comprenne en outre une fonction de support. Il s'agit d'une fonction de support pour le dispositif seul et/ou pour l'appareil électronique lorsque le dispositif et l'appareil sont assemblés au moyen d'une liaison rigide. On entend par fonction support tout moyen pour poser et/ou fixer le ou les éléments concernés sur une surface, d'une manière stable et en relation avec leur utilisation et/ou leur rangement. Il peut s'agir par exemple d'un piètement fixe ou escamotable, d'une ventouse, d'une fixation magnétique, d'une fixation par serrage entre des mâchoires.
L'inclusion d'une fonction support dans le dispositif selon l'invention est particulièrement pertinente pour une utilisation en accessoire d'un appareil électronique portable fixé au-dessus du dispositif. En effet, dans ce cas d'assemblage, la surélévation par rapport au plan de pose rend inopérantes les solutions de support éventuellement intégrée dans l'appareil portable comme par exemple les béquilles dont la longueur est calculée pour un appareil posé directement sur un plan.It is provided in the invention that the device further comprises a support function. It is a support function for the device alone and / or for the electronic device when the device and the device are assembled by means of a rigid connection. Support function means any means for placing and / or fixing the element or elements concerned on a surface, in a stable manner and in relation to their use and / or storage. It may be for example a fixed or retractable base, a suction cup, a magnetic attachment, a clamping attachment between jaws.
The inclusion of a support function in the device according to the invention is particularly relevant for an accessory use of a portable electronic device fixed above the device. Indeed, in this case of assembly, the elevation with respect to the laying plane makes inoperative support solutions possibly integrated into the portable device such as crutches whose length is calculated for a device placed directly on a plane.

Suivant un autre aspect de l'invention, il est proposé un système pour recevoir et/ou émettre des signaux radiofréquences et les exploiter en mobilité comprenant :

  • Un dispositif de réception tel que défini précédemment.
  • Un appareil électronique portable auquel le dispositif est connecté.
According to another aspect of the invention, there is provided a system for receiving and / or transmitting radio frequency signals and exploiting them in mobility, comprising:
  • A reception device as defined above.
  • A portable electronic device to which the device is connected.

Dans un premier cas d'application du système selon l'invention, il s'agit de rendre possible la réception de la télévision numérique au moyen d'un appareil électronique et d'un accessoire comprenant au moins deux antennes inamovibles. L'invention vise en outre à rendre encore plus compact le système constitué de l'appareil électronique portable et de l'accessoire de réception en ce que les antennes sont au moins en partie rétractables et ou pliables et qu'elles peuvent être déployées selon les besoins. On entend par déployées selon les besoins, déployées d'une manière qui prend en compte l'encombrement des boîtiers de l'appareil portable et de l'accessoire et/ou qui permet d'obtenir une réception satisfaisante dans des conditions de positionnement données. On entend par une utilisation en mobilité, la réception de la télévision numérique pendant que l'ensemble du système de réception selon l'invention est mobile parce qu'il est tenu, porté ou fixé par un moyen approprié à un utilisateur qui bouge. Il peut s'agir également de la fixation ou de la pose du système selon l'invention dans un ensemble mobile qui contient l'utilisateur tel qu'un moyen de transport terrestre, aérien ou maritime privé ou public. Il peut aussi s'agir d'une mobilité préalable à l'usage du système selon l'invention et de l'utilisateur avant une utilisation effective statique du système. Cette mobilité préalable à l'usage peut avoir lieu par exemple au sein d'un local professionnel ou d'habitation.
On entend par réception de la télévision numérique la réception de signaux de télévision numérique diffusés par des moyens d'infrastructure selon des standards tels que par exemple DVB-T, DVB-H, T-DMB, CDMB etc.
On entend aussi par réception de la télévision numérique, la réception de tous signaux transmis par des moyens sans fil compatibles avec le dispositif et transportant de la vidéo jusqu'au système selon l'invention. Il peut s'agir par exemple de recevoir un flux vidéo provenant d'un point d'accès à un réseau local ou à un réseau distant selon des standards tels que par exemple WiFi, WiMax, WUSB, Bluetooth. Il peut également s'agir d'un flux provenant directement d'un autre appareil dans le cadre d'une liaison point à point ou point-multipoint. La plupart de ces standards ou de leurs variantes, par exemple 802.11n, pouvant tirer partie de la diversité d'antennes caractéristique de l'accessoire selon l'invention pour améliorer les performances de la liaison.
La source de signaux peut par exemple être un lecteur-enregistreur vidéo numérique, un récepteur/décodeur dit « set top box » ou encore un appareil embarqué dans un moyen de transport, par exemple dans le coffre à bagage d'une voiture ou dans un compartiment technique d'un moyen de transport en commun pour stocker des contenus et/ou pour recevoir des flux issus d'une liaison primaire tel qu'un réseau de diffusion numérique terrestre ou satellitaire.
Le signal reçu et exploité par l'accessoire selon l'invention peut être associé à un canal unique ou à une pluralité de canaux répartis en paquets ou multiplexés dans le temps ou dans l'espace des fréquences sans sortir du cadre de l'invention.
Bien entendu, on reste dans le cadre de l'invention en ne traitant uniquement qu'un flux numérique audio dans le cadre d'une application de l'invention restreinte à la seule réception et/ou émission de son.In a first case of application of the system according to the invention, it is to make possible the reception of digital television by means of an electronic device and an accessory comprising at least two irremovable antennas. The invention also aims at making the system consisting of the portable electronic device and the receiving accessory even more compact in that the antennas are at least partly retractable and or foldable and that they can be deployed according to the needs. Deployed as required, deployed in a manner that takes into account the bulk of the housings of the portable device and the accessory and / or which provides a satisfactory reception under given positioning conditions. By mobile use is meant the reception of the digital television while the entire reception system according to the invention is mobile because it is held, worn or fixed by a suitable means to a user who moves. It may also be the fixing or laying of the system according to the invention in a mobile assembly that contains the user such as a means of transport land, air or sea private or public. It may also be a mobility prior to the use of the system according to the invention and the user before an actual static use of the system. This mobility prior to use can take place for example within a professional or residential premises.
The reception of digital television is understood to mean the reception of digital television signals broadcast by infrastructure means according to standards such as, for example, DVB-T, DVB-H, T-DMB, CDMB, etc.
The reception of digital television is also understood to mean the reception of all signals transmitted by wireless means compatible with the device and carrying video to the system according to the invention. It may be for example to receive a video stream from an access point to a LAN or a remote network according to standards such as for example WiFi, WiMax, WUSB, Bluetooth. It can also be a stream coming directly from another device as part of a point-to-point or point-to-multipoint link. Most of these standards or their variants, for example 802.11n, can take advantage of the antenna diversity characteristic of the accessory according to the invention to improve the performance of the link.
The signal source may for example be a digital video player-recorder, a "set-top box" receiver or decoder or an apparatus embedded in a means of transport, for example in the luggage compartment of a car or in a vehicle. technical compartment of a means of public transport for storing contents and / or for receiving streams originating from a primary link such as a digital terrestrial or satellite broadcasting network.
The signal received and used by the accessory according to the invention may be associated with a single channel or with a plurality of channels distributed in packets or multiplexed in time or in the frequency space without departing from the scope of the invention.
Naturally, it remains within the scope of the invention to deal only with a digital audio stream in the context of an application of the invention restricted to the sole reception and / or sound emission.

Dans un second cas d'application du système selon l'invention, il s'agit de rendre possible la réception d'informations de géo localisation au moyen d'un appareil électronique et d'un accessoire comprenant au moins deux antennes inamovibles. L'application du système selon l'invention dans ce contexte permet d'atteindre une qualité de service supérieure à celles qu'offrent les solutions à l'état de l'art. L'augmentation de la qualité de service se concrétise par une disponibilité supérieure du service dans des contextes où les solutions à l'état de l'art ne sont plus fonctionnelles et/ou par une augmentation de la précision des informations fournies.
Le système selon l'invention convient à une utilisation piétonne et/ou embarquée dans un véhicule.In a second case of application of the system according to the invention, it is to make possible the receipt of geolocation information by means of an electronic device and an accessory comprising at least two irremovable antennas. The application of the system according to the invention in this context makes it possible to achieve a higher quality of service than those offered by state-of-the-art solutions. The increase in the quality of service is reflected by a higher availability of the service in contexts where the state-of-the-art solutions are no longer functional and / or by increasing the accuracy of the information provided.
The system according to the invention is suitable for pedestrian use and / or embedded in a vehicle.

Dans un troisième cas d'application du système selon l'invention, il s'agit de rendre possible la connexion d'un appareil électronique portable à un réseau local et/ou d'infrastructure au moyen d'un appareil électronique et d'un accessoire comprenant au moins deux antennes inamovibles.In a third case of application of the system according to the invention, it is to make possible the connection of a portable electronic device to a local network and / or infrastructure by means of an electronic device and a accessory comprising at least two irremovable antennas.

Description détaillée des figuresDetailed description of the figures

  • - La figure 1 illustre une première variante simple et compacte de l'invention. Le dispositif selon l'invention est agencé pour se connecter mécaniquement et électriquement à un appareil électronique portable. Des liaisons à un ou plusieurs degrés de liberté 3, 6 permettent de déployer les antennes télescopiques 2 de chaque côté de l'appareil électronique portable. On reste dans le cadre de l'invention s'il n'y a qu'un seul brin 4 rétractable dans le boîtier du dispositif sachant qu'un nombre supérieur de tubes télescopiques 5 peut être nécessaire pour atteindre une longueur d'antenne déployée optimale relativement aux longueurs d'ondes utilisées. Des forces de friction sont mises en oeuvre dans toutes les liaisons mécaniques 3, 6 pour conserver les positions relatives des éléments entre eux, par exemple pour conserver une position des antennes qui donne de bons résultats.- The figure 1 illustrates a first simple and compact variant of the invention. The device according to the invention is arranged to connect mechanically and electrically to a portable electronic device. Links with one or more degrees of freedom 3, 6 make it possible to deploy the telescopic antennas 2 on each side of the portable electronic device. It remains within the scope of the invention if there is only one retractable strand 4 in the housing of the device knowing that a greater number of telescopic tubes 5 may be necessary to achieve an optimal deployed antenna length. relative to the wavelengths used. Friction forces are used in all the mechanical links 3, 6 to maintain the relative positions of the elements together, for example to maintain a position of the antennas which gives good results.
  • - La figure 2 illustre la variante de mise en oeuvre précédente de l'invention en position repliée. Les deux antennes télescopiques 2 sont entièrement rétractées dans le boitier du dispositif 1 selon l'invention permettant ainsi la réalisation d'un accessoire particulièrement compact pour le rangement et le transport.- The figure 2 illustrates the previous implementation variant of the invention in the folded position. Both telescopic antennas 2 are fully retracted into the housing of the device 1 according to the invention thus allowing the realization of a particularly compact accessory for storage and transport.
  • - La figure 3 illustre la variante de mise en oeuvre précédente de l'invention en position opérationnelle avec les antennes 2 déployées. Le dispositif 2 et l'appareil 7 forment un système monobloc fonctionnel et esthétique pouvant être posé et tenu en main(s) sans qu'aucun câble ne gêne l'utilisateur.- The figure 3 illustrates the previous implementation variant of the invention in operational position with the deployed antennas 2. The device 2 and the device 7 form a functional and aesthetic monobloc system that can be placed and held in the hand without any cable interfering with the user.
  • - La figure 4 illustre une autre variante de mise en oeuvre de l'invention. Elle diffère de la précédente en ce que les brins actifs 4 des antennes 2 sont agencés pour être éloignés davantage les uns des autres et collectivement de l'appareil électronique portable. Ceci permettant respectivement, à la fois d'améliorer le gain apporté par la mise en oeuvre de la diversité, et d'améliorer le rapport signal sur bruit par éloignement des antennes de la source de bruit que constitue l'appareil. Avantageusement, les antennes comprennent un fourreau horizontal 8 dont la partie externe est à la masse et qui joue le rôle de conducteur coaxial pour alimenter le brin rayonnant. La réalisation électrique et mécanique est simplifiée en ce que les lignes d'alimentations ainsi constituées sont sensiblement adaptées en position complètement déployées des fourreaux. Cette position étant celle qui maximise les performances du système en fonctionnement.- The figure 4 illustrates another variant of implementation of the invention. It differs from the previous one in that the active strands 4 of the antennas 2 are arranged to be further apart from each other and collectively from the portable electronic device. This allows, respectively, both to improve the gain provided by the implementation of the diversity, and improve the signal-to-noise ratio away from the antennas of the noise source that constitutes the device. Advantageously, the antennas comprise a horizontal sleeve 8 whose outer portion is grounded and which acts as a coaxial conductor for supplying the radiating strand. The realization Electrical and mechanical is simplified in that the power lines thus formed are substantially adapted in fully deployed position of the sleeves. This position is the one that maximizes the performance of the system in operation.
  • - La figure 5 illustre la variante de mise en oeuvre précédente de l'invention en position repliée.- The figure 5 illustrates the previous implementation variant of the invention in the folded position.

  • - La figure 7 illustre le système de la figure 6 en vue de côté. On distingue la languette 9 dépliée faisant fonction de pied qui maintient l'ensemble du système en position stable et avantageusement inclinée d'un angle approprié pour que l'axe de vision de l'utilisateur 10 soit sensiblement perpendiculaire à la surface de l'écran.- The figure 7 illustrates the system of figure 6 in side view. There is the tab 9 unfolded foot function which keeps the entire system in a stable position and advantageously inclined at an appropriate angle so that the axis of vision of the user 10 is substantially perpendicular to the surface of the screen .
  • - La figure 8 illustre une variante de mise en oeuvre de l'invention qui permet l'adaptation du dispositif 1 à un appareil électronique portable 7 du type téléphone, ayant une orientation en utilisation où la plus grande longueur du boîtier et/ou de l'écran se trouve à la verticale.- The figure 8 illustrates an alternative embodiment of the invention that allows the adaptation of the device 1 to a portable electronic device 7 of the telephone type, having an orientation in use where the greatest length of the housing and / or the screen is vertically.

Le dispositif peut être connecté à l'appareil portable par l'un quelconque de ses côtés sans sortir du cadre de l'invention. Lorsqu'un ou plusieurs connecteurs sont utilisés simultanément pour assurer la fixation mécanique et la connexion électrique amovibles entre le dispositif et l'appareil, c'est la position du ou des connecteurs qui détermine le positionnement relatif du dispositif selon l'invention par rapport à l'appareil.- The figure 10 illustrates an alternative embodiment of the invention that allows the adaptation of the device 1 to a portable electronic device 7 of the game console type having an orientation in use where the greatest length of the housing and / or the screen is found horizontally. The device can be connected to the portable device by any of its sides without departing from the scope of the invention. When one or more connectors are used simultaneously to ensure the mechanical attachment and the electrical connection removable between the device and the device, it is the position of the connector or connectors which determines the relative positioning of the device according to the invention with respect to the device.
  • - La figure 11 illustre une variante de mise en oeuvre de l'invention qui permet l'adaptation du dispositif 1 à un appareil électronique portable 7 ayant une orientation en utilisation où la plus grande longueur du boîtier et/ou de l'écran se trouve à l'horizontale. Avantageusement, dans cette variante, chaque antenne 2 est déployable par mise en oeuvre de solutions différentes, par exemple un simple fouet télescopique déployable verticalement et un autre fouet permettant une orientation verticale ou horizontale. Un boîtier comprenant des surfaces métalliques faisant fonction de plan de masse sera avantageusement retenu.- The figure 11 illustrates an alternative embodiment of the invention that allows the adaptation of the device 1 to a portable electronic device 7 having an orientation in use where the greatest length of the housing and / or the screen is horizontal . Advantageously, in this variant, each antenna 2 is deployable by implementing different solutions, for example a simple telescopic whip vertically deployable and another whip for vertical or horizontal orientation. A housing comprising metal surfaces acting as a ground plane will advantageously be retained.
  • - La figure 12 illustre par une vue de dessus et par deux vues de côté, une variante de mise en oeuvre du dispositif 1 selon l'invention sous la forme d'un stick USB en position repliée pour le rangement.
