A portable casing comprising the electrical power system and amplifiers, and connected to headphones, will enable the radio card to be used outside the vehicle.

Description

Système auto-radio extractible format"carte de crédit" ou commande tuner enfichable. "Credit card" extractable car radio system or plug-in tuner control.

La présente invention s'applique principalement au système déjà déposé sous le même titre tel qu'il est défini en tant que procédé et revendiqué par la demande de brevet Nu87.14030 en date du 12
Octobre 1987 par Mademoiselle Marie-Christine ROLLAND.The present invention mainly applies to the system already deposited under the same title as it is defined as a process and claimed by patent application Nu87.14030 dated 12
October 1987 by Mademoiselle Marie-Christine ROLLAND.

La présente invention concerne plus spécifiquement la carte radio ou commande tuner destinée à etre introduite dans la fente (12) prévue à cet effet sur la face avant (10) du bloc amplificateur (11). The present invention relates more specifically to the radio card or tuner control intended to be inserted into the slot (12) provided for this purpose on the front face (10) of the amplifier block (11).

Le raccordement de la carte radio sur le bloc amplificateur ne doit pas être réalisé par des contacts électriques pour des raisons de fiabilité. En effet, l'extraction et l'insertion de la carte pouvant être faites plusieurs fois par jour, le risque d'usure rapide des contacts est à craindre. Ces contacts peuvent aussi être détériorés par les clés et pièces de monnaie, lors du transport de la carte dans une poche. The connection of the radio card to the amplifier block must not be made by electrical contacts for reasons of reliability. Indeed, the extraction and insertion of the card can be done several times a day, the risk of rapid wear of the contacts is to be feared. These contacts can also be damaged by keys and coins, when transporting the card in a pocket.

L'analyse des fonctions du nouveau système de prise et de sélection des ondes (commande tuner format "carte de crédit") fait apparaître deux types de signaux: Ceux qui entrent dans la carte radio, ceux qui sortent de la carte radio, d'où l'existence d'une zone de couplage des-signaux en question,(Figure N01)
Signaux entrant dans la carte radio: a) Le signal haute fréquence provenant de l'antenne. b) L'énergie électrique d'alimentation:
L'interconnexion du signal haute fréquence sera réalisée à l'aide d'un condensateur composé de deux plaques métalliques isolées, placées en regard l'une de l'autre, situées, l'une dans le bloc amplificateur, l'autre dans la carte radio.L'énergie électrique sera transmise par deux bobinages couplés; l'un situé dans le bloc alimentation et parcouru par un signal alternatif provenant d'un petit convertisseur, l'autre situé dans la carte et captant l'énergie.Analysis of the functions of the new wave pick-up and selection system (tuner command "credit card" format) reveals two types of signals: Those entering the radio card, those leaving the radio card, where the existence of a coupling zone of the signals in question, (Figure N01)
Signals entering the radio card: a) The high frequency signal from the antenna. b) Electric power supply:
The interconnection of the high frequency signal will be carried out using a capacitor composed of two insulated metal plates, placed opposite one another, located, one in the amplifier block, the other in the radio card. The electrical energy will be transmitted by two coupled windings; one located in the power supply unit and traversed by an alternating signal from a small converter, the other located in the card and capturing energy.

c) Signaux sortant de la carte radio: Ces signaux sont ceux du signal basse fréquence stéréophonique; leur interconnexion sera faite par liaison capacitive sur le même principe que la liaison haute fréquence, mais en utilisant des diélectriques céramiques à fort coefficient, et des circuits à trés haute impédance d'entrée dans le bloc amplificateur.c) Signals leaving the radio card: These signals are those of the low-frequency stereophonic signal; their interconnection will be made by capacitive link on the same principle as the high frequency link, but using ceramic dielectrics with high coefficient, and circuits with very high input impedance in the amplifier block.

Position de la carte (Figure N01): Afin de permettre l'implantation du nombre maximum de touches, l'insertion de la carte se fera latéralement. Dans ces conditions, sur la partie extérieure de la carte (6), il sera possible d'implanter huit fonctions qui seront: sélection GO et FM (1), recherche des stations (2), et cinq mémoires (3); ces mémoires seront prises en charge en fonction du choix de la gamme d'ondes; lorsque la station choisie est repérée, un délai de vingt secondes permet la mise en mémoire. Card position (Figure N01): In order to allow the implantation of the maximum number of keys, the card will be inserted laterally. Under these conditions, on the external part of the card (6), it will be possible to set up eight functions which will be: GO and FM selection (1), station search (2), and five memories (3); these memories will be supported according to the choice of the wave range; when the chosen station is identified, a delay of twenty seconds allows storage.

Un affichage lumineux à cristaux liquides (4) situé au-dessus des touches numériques à effleurement (1.2.3) indiquera la fréquence de l'émetteur reçu.A luminous liquid crystal display (4) located above the touch-sensitive numeric keys (1.2.3) will indicate the frequency of the received transmitter.

Maintien de la carte radio (Figures 1 et 2): Au moment de l'insertion de la carte, un système mécanique à ressort (7) se déclenchera et pressera sur la partie arrière de la carte (5), afin de la maintenir en position, et d'assurer parfaitement les couplages capacitifs et électromagnétiques. Une pression sur un bouton (8) libèrera cette fixation et fera avancer la carte de un centimètre afin de pouvoir la récupérer. La partie extérieure de la carte radio (6) reposera sur un petit piédestal (9) en caoutchouc dur afin de limiter les contraintes mécaniques lors de la manipulation des touches à effleurement. Maintaining the radio card (Figures 1 and 2): When inserting the card, a mechanical spring system (7) will activate and press on the rear part of the card (5), in order to keep it in position, and perfectly ensuring the capacitive and electromagnetic couplings. Pressing a button (8) will release this fixation and advance the card by one centimeter in order to be able to recover it. The external part of the radio card (6) will rest on a small pedestal (9) made of hard rubber in order to limit mechanical stresses when handling the touch buttons.

Codage confidentiel: Un code sera émis par la carte radio au moment de la mise sous tension du boîtier amplificateur, et permettra la mise en route de l'ensemble de l'appareil. Ce code sera du type lecture magnétique, tel que celui utilisé sur les cartes de crédit, ou du type électromagnétique, tel que celui utilisé sur certains systèmes de sécurité automobile. Ce code confidentiel sera enregistré sur une carte magnétique livrée avec le matériel au moment de l'achat, afin de pouvoir introduire le code initial sur une seconde carte radio en cas de perte. Confidential coding: A code will be sent by the radio card when the amplifier box is switched on, and will allow the whole device to be started up. This code will be of the magnetic reading type, such as that used on credit cards, or of the electromagnetic type, such as that used on certain automobile security systems. This confidential code will be recorded on a magnetic card delivered with the equipment at the time of purchase, in order to be able to enter the initial code on a second radio card in the event of loss.

Le système de codage ainsi défini peut engendrer de multiples autres usages. The coding system thus defined can generate multiple other uses.

Un boîtier portatif de la dimension d'un paquet classique de cigarettes, comprenant un système d'alimentation en énergie électrique (batterie d'accumulateur ou pile électrique) et des amplificateurs raccordés à un petit casque pliable permettra à l'utilisateur de la carte radio de terminer l'écoute de la station sur laquelle il est branché, à l'extérieur de son véhicule.  A portable box the size of a conventional pack of cigarettes, comprising an electrical energy supply system (accumulator battery or electric battery) and amplifiers connected to a small foldable headset will allow the user of the radio card. to finish listening to the station to which it is connected, outside of its vehicle.
