Abstract

The mechanical device for the orientation of the electromagnetic waves from a portable telephone handset comprises a movable flap (3) mounted on top of the telephone. This flap contains a reflector surface which fits behind the telephone aerial in order to reflect transmitted waves outwards away from the user's ear and head. The screen serves a dual purpose in that it also increase the sensitivity of the telephone to incoming signals, focussing such signals on to the aerial. The flap may be mounted on the telephone in such a way that it can slide between a retracted position where it lies close to the main body of the telephone, and an extended position in which it offers protection and serves as a reflector.

Description

La présente invention concerne un dispositif mécanique d'orientation des ondes électromagnétiques émises par un télé- phone mobile
Les téléphones mobiles classiques, figure 1 , comportent une antenne émettrice (2) fixée au corps (1) émettant des ondes dans toutes les directions et particulièrement vers le cerveau de l'utilisateur avec une possibilité d'action néfaste sur la santé .De plus des prothèses telles les simulateurs cardiaques peuvent être affectés dans leur fonctionnement
Une solution consiste d intégrer l'antenne au boitier et å placer un blindage coté utilisateur ,cependant l'écran ainsi réalisé est réduit en raison de la miniaturisation poussée de ce type d'appareil
Le dispositif selon l'invention permet de remédier å ce défaut en disposant un écran mobile (3) entre l'antenne et l'utilisateur . Cet écran offre une grande surface réflective et peut entre conformé pour améliorer la réception et l'emis- sion des ondes électromagnétiques .Figure 2
Dans le premier cas la sensibilité est améliorée et dans le deuxième cas la portée augmentée ,la consommation diminuée
Le dispositif réflecteur peut entre réalisé par formage superplastique d'un métal tel le titane ou bien par métallisation d'une pièce en plastique . Cette métallisation peut entre obtenue par shoopage ,dépôt chimique ou peinture conductrice.The present invention relates to a mechanical device for orienting the electromagnetic waves emitted by a mobile telephone.
Conventional mobile phones, Figure 1, have a transmitting antenna (2) fixed to the body (1) emitting waves in all directions and particularly towards the user's brain with a possibility of harmful action on health. prostheses such as cardiac simulators can be affected in their functioning
One solution consists of integrating the antenna into the box and placing a shield on the user side, however the screen thus produced is reduced due to the extensive miniaturization of this type of device.
The device according to the invention makes it possible to remedy this defect by providing a mobile screen (3) between the antenna and the user. This screen offers a large reflective surface and can be shaped to improve the reception and emission of electromagnetic waves. Figure 2
In the first case the sensitivity is improved and in the second case the increased range, the reduced consumption
The reflector device can between produced by superplastic forming of a metal such as titanium or by metallization of a plastic part. This metallization can be obtained by shooping, chemical deposition or conductive paint.

Selon un mode de réalisation préférentiel ,figure 3, l'é- cran réflecteur (3) est mobile en translation et sert de protection å l'écran en position fermée . Une glissière (5) guide la partie mobile et un bouton latéral (4) facilite le déplace- ment ,l'antenne (2) est aussi commandée en translation
La partie coulissante (3) peut comporter un écouteur (11) facilitant ainsi l'utilisation de l'appareil
L'antenne (2) habituellement placée sur le coté droit doit entre disposée en position centrale pour rayonner de façon ho morène
Selon un autre mode de réalisation préférentiel ,figure 4, l'écran (3) est articulé en (6) sur le corps (1)
L'écran est réaliste en deux parties dont une moitié sur le corps et en position fermée l'ensemble est protégé contre les agressions externes
L'ensemble est compact et ergonomique
Selon un mode de réalisation préférentiel ,l'antenne (2) est coaxiale à l'articulation (6) ,donc peu encombrante en position fermée . Le volet (3) comporte au dos un écouteur (7) pour rendre le tout plus ergonomique
Selon un autre mode de réalisation le volet articulé (3)
comporte une surface réfléchissante concentrique et l'antenne (2) est fixée au centre de symétrie de celle-ci, figure 5
L'autre face du volet (3) comporte un écouteur ;grâce à cette disposition constructive l'cran (8) est protégé en position fermée
L'alimentation de l'antenne doit entre assurée par un con docteur blindé
Le dispositif selon l'invention est particulièrement des- tiné à la fabrication industrielle de téléphones mobiles tenant compte des impératifs de protection contre les ondes électromagnétiques en usage intensif . Le concept permet en outre d'améliorer les performances d'émission et de réception According to a preferred embodiment, in FIG. 3, the reflective screen (3) is movable in translation and serves to protect the screen in the closed position. A slide (5) guides the mobile part and a lateral button (4) facilitates movement, the antenna (2) is also controlled in translation
The sliding part (3) may include an earpiece (11) thus facilitating the use of the device
The antenna (2) usually placed on the right side must between placed in a central position to radiate in a ho morene way
According to another preferred embodiment, FIG. 4, the screen (3) is articulated at (6) on the body (1)
The screen is realistic in two parts, half of which is on the body and in the closed position the assembly is protected against external aggressions
The set is compact and ergonomic
According to a preferred embodiment, the antenna (2) is coaxial with the articulation (6), therefore compact in the closed position. The flap (3) has an earpiece (7) on the back to make everything more ergonomic
According to another embodiment, the articulated flap (3)
has a concentric reflecting surface and the antenna (2) is fixed to the center of symmetry thereof, Figure 5
The other face of the flap (3) includes an earpiece; thanks to this constructive arrangement the screen (8) is protected in the closed position
The antenna supply must be ensured by an armored doctor
The device according to the invention is particularly intended for the industrial manufacture of mobile telephones taking into account the imperatives of protection against electromagnetic waves in intensive use. The concept also improves transmission and reception performance
