Abstract

One or more contacts (4) are mounted on the sides of the case for access by the user. The case is seated between the thumb and index finger so that the index finger can exert the appropriate pressure. On pressing or holding down a first contact, a list of geographical areas is displayed in alphanumeric form and data (5) is selected by pressing a second contact. The display can alternate between the place name and the frequency. Where the length of the name exceeds the character length of the display, it scrolls right to left. It can include satellite and cable channels as well as terrestrial broadcasts.

Description

La présente invention concerne un dispositif électronique de dimensions réduites destiné à afficher notamment les fréquences des émetteurs de radio diffusé par voie hertzienne, par le câble ou le satellite, les canaux de télévision diffusés par voie hertzienne, par le câble ou le satellite, en fonction de la position géographique de réception, et du nom du diffuseur. En complément pourront s'afficher des messages alphanumériques. The present invention relates to an electronic device of reduced dimensions intended to display in particular the frequencies of radio transmitters broadcast over the air, by cable or satellite, television channels broadcast over the air, by cable or satellite, in function the geographical position of reception, and the name of the broadcaster. In addition, alphanumeric messages may be displayed.

La liste des fréquences des émetteurs doit être traditionnellement consultée sur des formulaires imprimés ou bien dans des magazines grand public ou spécialisés; cela entraîne bien souvent une recherche fastidieuse ou bien la nécessité de faire défiler toutes les fréquences sur un appareil de réception pour trouver l'emetteur que l'on cherche, opération qui peut devenir dangereuse dans le cas où l'automobliste risque de perdre son attention de conduite lorsqu'il cherchera sa station sur l'autoradio. The list of transmitters' frequencies must traditionally be consulted on printed forms or in consumer or specialist magazines; this often leads to a tedious search or the need to scroll through all the frequencies on a receiving device to find the transmitter that we are looking for, an operation that can become dangerous in the event that the car driver risks losing his attention when he searches for his station on the car radio.

Le dispositif électronique de l'invention va permettre de remédier à cela. En effet, par ses dimensions réduites, il va pouvoir être emmené partout avec soi, notamment sous la forme d'un porte-clés. The electronic device of the invention will make it possible to remedy this. Indeed, by its reduced dimensions, it will be able to be taken everywhere with you, especially in the form of a key ring.

Le dispositif affiche de façon trés rapide la fréquence désirée au moyen d'un afficheur à cristaux liquides qui va séquentiellement indiquer le nom du lieu géographique puis la fréquence correspondante de la station recherchée. The device very quickly displays the desired frequency by means of a liquid crystal display which will sequentially indicate the name of the geographical location then the corresponding frequency of the desired station.

Le dispositif électronique va être logé dans un boîtier qui comportera un ou plusieurs contacts et qui pourra comporter sur un de ses côtés le nom de la station d'émission. Une simple pression sur un contact va permettre de faire défiler la liste des lieux géographiques (noms de villes, de régions, de pays, etc. .) sur l'afficheur à cristaux liquides; le relâchement du contact va provoquer l'affichage alterné de la fréquence et du nom du lieu géographique qui défilait au moment du relâchement du contact. The electronic device will be housed in a box which will include one or more contacts and which may have on one of its sides the name of the transmitting station. A simple press on a contact will scroll through the list of geographic places (names of cities, regions, countries, etc.) on the liquid crystal display; releasing the contact will cause the frequency and name of the geographic location that was scrolling alternately to be displayed alternately when the contact is released.

Les dessins annexés illustrent une application de l'invention - La figure 1 représente l'application du dispositif en perspective. The accompanying drawings illustrate an application of the invention - Figure 1 shows the application of the device in perspective.

- La figure 2 représente l'application du dispositif en coupe.- Figure 2 shows the application of the device in section.

En référence à ces dessins, le dispositif comporte un boîtier (1) dans lequel est logé le système électronique (2), sur la face supérieure du dispositif est logé l'afficheur de fréquences(3), le côté du boîtier est muni d'un bouton poussoir (4) qui par un contact impulsionnel sélectionne la ville (5). With reference to these drawings, the device comprises a box (1) in which is housed the electronic system (2), on the upper face of the device is housed the frequency display (3), the side of the box is provided with a push button (4) which by impulse contact selects the city (5).

Le dispositif selon l'invention est particulièrement destiné à l'industrie de la communication. The device according to the invention is particularly intended for the communication industry.

Claims

1) Electronic device (2) of reduced dimensions intended to display in particular the frequencies of the radio transmitters (3), broadcast by hertzian way, by the cable or the satellite or the television channels broadcast by hertzian way, by the cable or the satellite depending on the geographic location of reception (5) and the name of the broadcaster. In addition, alphanumeric messages may be displayed. The device is designed to be placed in a box (1) which can optionally be mounted as a key ring (6). The display is carried out by means of a liquid crystal panel which is managed by an electronic circuit using microprocessor technology or programmable logic circuit technology. One or more contacts (4) are mounted on the dimensions of the housing; these contacts being accessible by the user. By pressing a first contact (4) of the box in an impulse or maintained manner, the list of geographic places (3) is displayed in alphanumeric form on the liquid crystal panel then the data (5) is selected by a second impulse contact .

2) Device according to claim 1, characterized in that the contact or contacts are located in such a way that the user grasping the housing between the thumb and the index finger can exert a prolonged or impulse pressure on these.

3) Device according to claim 1 or claim 2 characterized in that the display of frequencies on the liquid crystal panel will be alternated with the name of the geographical location.

4) Device according to the preceding claims according to which the display of the name of the cities whose number of characters will be greater than the number of alphanumeric characters of the display will be carried out in side scrolling mode from right to left.
