Description

DISPOSITIF DE PROTECTION DES PERSONNES VIS A VIS DES ONDES ELECTROMAGNETIQUES L'invention se rapporte au domaine technique des moyens de protection des personnes vis à vis des ondes hyper-fréquences et ondes électromagnétiques. L'apparition et le développement commercial des téléphones portables, des fours à micro-ondes, ainsi que la multiplication des stations de radio ou de télévision font que les personnes vivent dans un brouillard électromagnétique de plus en plus dense. La difficulté de visualiser de telles ondes électromagnétiques a conduit, tout comme pour ce qui s'est passé en matière de radioprotection, à un fort besoin sociétal d'informations et de protections. En ce qui concerne l'incidence éventuelle de la téléphonie mobile sur la santé des personnes, de vives controverses existent depuis de nombreuses années. Une des difficultés consiste dans la mesure du débit d'absorption spécifique, puissance absorbée en watt par kilogramme de tissu vivant. Les mesures de DAS in vivo ne sont, bien entendu, pas possibles par sonde sensible au champ électrique ou à la température. L'imagerie médicale IRM et les méthodes numériques de calcul électromagnétique permettent l'estimation des champs électrique et magnétique mais il s'avère difficile de modéliser numériquement un radiotéléphone (cf modèles FTRD France Telecom ENST). Les calculs effectués suivants les modèles existants pour les GSM donnent un DAS de 1 watt/kilogramme, 13% de cette puissance étant absorbée par le cerveau, 30% de l'énergie étant absorbée dans un cube de 5 cm centré sur l'oreille interne, le DAS maximum estimé dans l'oreille interne étant de l'ordre de 0,4 watt/Kg pour une puissance de 250 mW et à une fréquence GSM de 900 Mhz. Bien que les mesures de DAS donnent lieu à une incertitude de 35%, les réglementations nationales européennes en font état, car le DAS est le seul paramètre physique mesurable reconnu de manière unanime par la communauté technique et scientifique pour ce qui est des effets sanitaires des champs électromagnétiques des GSM. Ainsi, la puissance crête maximum autorisée en France pour les GSM est de 2 watts à 900 Mhz et de 1 watt à 1800 Mhz, avec découpage TDMA en 217 Hertz, le DAS maximum admissible étant fixé à 0,08 watt/Kg pour le public (règlement 1999/519CE) avec 2 watt/Kg localement pour 10 grammes de tissu. A titre indicatif, une valeur moyenne de conductivité de lS/m pour un tissu, à 900 Mhz, donne une intensité de champ électrique de 30 V/m pour obtenir un DAS de 1 W/Kg. Les champs électromagnétiques liés à la téléphonie mobiles entre 850 et 1900 Mhz ont un effet thermique apparent faible (moins de 0.1 degré). De très nombreuses études ont été réalisées sur les effets sanitaires de ces ondes : - système cardio-vasculaire (pression artérielle, rythme cardiaque), - cancers (gliomes, méningliomes, neurinome de l'acoustique, cancers des glandes parotides), - reproduction et développement embryonnaire, - système immunitaire (IgA) et endocrinien (mélatonine, cortisol), - fonctions cognitives telles que mémoire, attention, concentration, sommeil, céphalées, épilepsie, - barrière hémato-encéphalique, - protéine de choc thermique. Des études ont concerné les symptômes qui ne peuvent être objectivés par médecin (fatigue, sensation de chaleur, irritabilité, vertiges). Ces études épidémiologiques ne peuvent que difficilement être affirmatives quant à l'impact de la téléphonie mobile sur la santé des personnes, dans la mesure où il n'est pas notamment envisageable de procéder à des essais en double aveugle. Plusieurs articles de presse dans les revues de vulgarisation scientifiques ont, par ailleurs, fait état de l'effet potentiellement nocif des ondes électromagnétiques. La grande presse nationale, notamment française, fait régulièrement état de cette question : voir par exemple dans le quotidien de Monde 10 mars 1999, 30 janvier 2001, 11 septembre 1996, 28 mars 2002. Un très grand nombre de demandes de brevet a été déposé antérieurement pour des dispositifs visant à protéger les utilisateurs de téléphones cellulaires (voir classes européennes H01Q1/24A1C et H04B1/38P2E). On peut se reporter, par exemple, aux documents WO-03/005487, FR- 2.826.784, FR-2.781.088, WO-03/043122, dont certains sont issus du présent inventeur. Le présent inventeur n'est pour l'heure pas parvenu à expliquer les mécanismes physiques mis en jeu dans l'invention qui va maintenant être exposée. Il semble, mais cela n'a pu être vérifié par le présent inventeur, que l'invention ne comprend pas à proprement parler une antenne (voir, par comparaison, les documents US-5.627.552, US-3.582.951 et US-5.451.965) du type dipôle de hertz replié ou Yagi, ou bien encore cadre de boucle magnétique. Le présent inventeur a, par ailleurs, comme toutes les personnes du métier en cause, rencontré des difficultés importantes pour réaliser des mesures de DAS permettant de démontrer l'effet bénéfique de son dispositif. Le présent inventeur a découvert que l'appareil BEST MSA 21 type B classe 2 série 1455 de la société Intertek Testing Services, effectuant des mesures par électro-acupuncture sur des points situés sur la main du patient, permet de visualiser et de mesurer un effet pour la présente invention, cet effet étant amélioré par rapport à ceux obtenus avec les dispositifs antérieurs, notamment ceux décrits dans les documents WO-03/005487, FR-2.826.784 et FR-2.781.088. Pour réaliser les mesures avec l'appareil BEST MSA 21, le protocole suivant a été respecté : 1) vérification des champs électriques, magnétiques et ondes électromagnétiques dans le local d'essai à l'aide d'un mesureur de champ (1Hz à 2.000 Hz) de marque Krystal M 840 D modifié Faditech type Z 5000, d'un mesureur de champ HF à large bande (23 MHz à 16GHz) de marque Faditech type L.B série 683, et d'une sonde blindée adaptée au Z 5000 ci-dessus. A titre indicatif, lors des essais, la valeur de champ E à 50 Hz était de l'ordre de 2V/m, le champ magnétique à 50 Hz était inférieur à 0,01 nT et les ondes électromagnétiques non décelables pour les bandes FM, VHF, UHF et micro-ondes, une valeur de 0,1 mW étant mesurée pour les ondes courtes deThe invention relates to the technical field of means for protecting persons from hyper-frequency waves and electromagnetic waves. The appearance and commercial development of mobile phones, microwave ovens, as well as the proliferation of radio and television stations mean that people live in increasingly dense electromagnetic fog. The difficulty of visualizing such electromagnetic waves has led, as in the case of radiation protection, to a strong societal need for information and protection. As for the possible impact of mobile telephony on human health, there has been much controversy for many years. One of the difficulties consists in measuring the specific absorption rate, power absorbed in watts per kilogram of living tissue. In vivo SAR measurements are, of course, not possible with an electric field or temperature sensitive probe. MRI medical imagery and digital methods of electromagnetic calculation allow the estimation of electric and magnetic fields but it turns out to be difficult to model a radiotelephone numerically (see models FTRD France Telecom ENST). The calculations made following the existing models for GSM give a SAR of 1 watt / kilogram, 13% of this power being absorbed by the brain, 30% of the energy being absorbed in a cube of 5 cm centered on the inner ear , the maximum SAR estimated in the inner ear being of the order of 0.4 watt / Kg for a power of 250 mW and at a GSM frequency of 900 Mhz. Although the SAR measurements give rise to an uncertainty of 35%, European national regulations state this, because the SAR is the only measurable physical parameter unanimously recognized by the technical and scientific community with regard to the health effects of the electromagnetic fields of mobile phones. Thus, the maximum peak power authorized in France for GSM is 2 watts at 900 Mhz and 1 watt at 1800 Mhz, with TDMA division into 217 Hertz, the maximum admissible SAR being fixed at 0.08 watt / Kg for the public (regulation 1999 / 519CE) with 2 watt / Kg locally for 10 grams of fabric. As an indication, an average conductivity value of lS / m for a fabric, at 900 MHz, gives an electric field intensity of 30 V / m to obtain a SAR of 1 W / Kg. The electromagnetic fields linked to mobile telephones between 850 and 1900 Mhz have a weak apparent thermal effect (less than 0.1 degree). Numerous studies have been carried out on the health effects of these waves: - cardiovascular system (blood pressure, heart rate), - cancers (gliomas, meningliomas, acoustic neuroma, cancers of the parotid glands), - reproduction and embryonic development, - immune system (IgA) and endocrine (melatonin, cortisol), - cognitive functions such as memory, attention, concentration, sleep, headache, epilepsy, - blood-brain barrier, - heat shock protein. Studies have concerned the symptoms which cannot be objected to by the doctor (fatigue, feeling of heat, irritability, dizziness). These epidemiological studies can hardly be affirmative as to the impact of mobile telephony on human health, since it is not in particular possible to carry out double-blind tests. Several press articles in popular science journals have also reported on the potentially harmful effect of electromagnetic waves. The major national press, particularly the French press, regularly reports on this issue: see for example in the daily newspaper Monde 10 March 1999, January 30, 2001, September 11, 1996, March 28, 2002. A very large number of patent applications have been filed previously for devices intended to protect users of cellular telephones (see European classes H01Q1 / 24A1C and H04B1 / 38P2E). Reference may be made, for example, to documents WO-03/005487, FR-2.826.784, FR-2.781.088, WO-03/043122, some of which come from the present inventor. The present inventor has so far failed to explain the physical mechanisms involved in the invention which will now be described. It seems, but this could not be verified by the present inventor, that the invention does not properly include an antenna (see, by comparison, documents US-5,627,552, US-3,582,951 and US- 5,451,965) of the folded hertz dipole or Yagi type, or even a magnetic loop frame. The present inventor has, moreover, like all those skilled in the art in question, encountered significant difficulties in performing SAR measurements making it possible to demonstrate the beneficial effect of his device. The present inventor has discovered that the BEST MSA 21 type B class 2 series 1455 device from the company Intertek Testing Services, performing measurements by electro-acupuncture on points located on the patient's hand, makes it possible to visualize and measure an effect. for the present invention, this effect being improved compared to those obtained with the prior devices, in particular those described in documents WO-03/005487, FR-2,826,784 and FR-2,781,088. To carry out the measurements with the BEST MSA 21 device, the following protocol was respected: 1) verification of the electric, magnetic and electromagnetic waves fields in the test room using a field meter (1Hz to 2.000 Hz) brand Krystal M 840 D modified Faditech type Z 5000, a broadband HF field meter (23 MHz to 16GHz) brand Faditech type LB series 683, and an armored probe suitable for Z 5000 above. As an indication, during the tests, the field value E at 50 Hz was of the order of 2V / m, the magnetic field at 50 Hz was less than 0.01 nT and the electromagnetic waves not detectable for the FM bands, VHF, UHF and microwave, a value of 0.1 mW being measured for short waves of
23 à 88 MHz. Pendant ces mesures, les téléphones portables des personnes présentes étaient éteints. La densité de puissance hyper-fréquence locale dans l'air mesurée avec le détecteur HFR1 de la société ROM Elektronik était de 0,30 W/m2 . 2) mesure avec l'appareil BEST MSA 21 type B classe série 1455 doté d'une masse en cuivre tenu dans la main du patient et d'une sonde électroacupuncture, dans les états suivants : - état neutre, - état portable allumé porté à 50 cm de la tête d'une personne testée, - état portable allumé porté à l'oreille par la personne testée, - état portable allumé avec le dispositif selon la présente invention fixé sur ce téléphone portable ou placé entre le téléphone et la main de la personne testée qui tient la masse en cuivre. Le présent inventeur a également pu vérifier la plus grande efficacité de la présente invention, par rapport aux dispositifs antérieurs, à l'aide des appareils suivants : - BICOM de Regumed Lochhamer Schlag, S.A ; - VEGATEST EXPERT de Vega AM Hohenstein ; - PROGNOS de MedPrevent GmbH & Co ; - PRT 2000S de Biomeridian. L'invention se rapporte, selon un premier objet, à un dispositif de protection des personnes vis à vis des ondes électromagnétiques, comprenant deux boucles sensiblement planes caractérisé en ce que les deux boucles sont sensiblement identiques et placées en regard l'une de l'autre et reliées électriquement entre elles par deux ponts distincts, les deux boucles étant isolées électriquement l'une de l'autre à l'exception desdits ponts. Dans une réalisation, lesdites boucles sont montées sur un circuit imprimé souple et recouvertes d'une plaque souple isolante en matériau polymère. D'autres objets et modes de réalisation de l'invention vont maintenant être décrits en référence aux dessins annexés, illustrant des modes de réalisation non limitatifs, dessins dans lesquels : - la figure 1 est une vue de face d'un dispositif selon un premier mode de réalisation, - les figures 2 et 3 sont des vues de face de deux autres modes de réalisation. Ainsi qu'il apparaît sur les figures, le dispositif comprend deux fils métalliques, par exemple, en cuivre ou alliage cuivreux, ces fils formant chacune une boucle 1,2, ces boucles étant placées en regard l'une de l'autre et étant de forme sensiblement identiques. Les boucles 1,2 sont placées en regard et isolées électriquement l'une de l'autre par une matière plastique telle que polyester, les deux boucles étant reliées entre elles par deux ponts 3,4, avantageusement formées par le fil constituant par ailleurs les deux boucles 1,2. La fabrication du dispositif peut être effectuée comme suit. Dans une première étape, un fil métallique, par exemple, de cuivre, est plié de sorte à former les boucles 1,2, les deux extrémités libres de ce fil étant soudées l'une à l'autre. On obtient, à l'issue de cette première étape, deux boucles sensiblement identiques, reliées par les ponts 3,4, l'ensemble étant sensiblement plan. Cet ensemble est alors placé dans une résine polymère isolante et les deux boucles sont repliées l'une vers l'autre avant que la résine ne durcisse. En variante, les deux boucles sont repliées avant d'être placées dans un moule dans lequel un matériau polymère est injecté. Selon une variante particulière, l'une des deux boucles est sensiblement homothetique à l'autre, mais légèrement plus grande, de l'ordre de quelques pourcents. Dans les modes de réalisation annexés, les deux boucles ne comportent chacune qu'une seule spire. Dans d'autres modes de réalisation, non représentés, chaque boucle comprend au moins deux spires sensiblement placées dans des plans parallèles. Dans une réalisation particulière, les boucles sont connectées à au moins un condensateur, en série et/ou en parallèle. Le dispositif peut être monté en bijou, en pendentif, en forme de bracelet ou de patch, ou bien encore contre un boîtier de montre ou plaqué sur un téléphone portable. La demanderesse a constaté des effets positifs sur des symptômes non objectivés, dès lors que le dispositif est porté en contact direct ou à proximité d'une partie du corps humain, par exemple cousu dans un vêtement. 23 to 88 MHz. During these measurements, the mobile phones of those present were turned off. The local hyper-frequency power density in air measured with the HFR1 detector from the company ROM Elektronik was 0.30 W / m 2 . 2) measurement with the BEST MSA 21 type B class 1455 series device with a copper mass held in the patient's hand and an electroacupuncture probe, in the following states: - neutral state, - portable state on brought to 50 cm from the head of a person tested, - portable state lit brought to the ear by the test person, - portable state lit with the device according to the present invention fixed on this portable telephone or placed between the telephone and the hand of the tested person holding the copper mass. The present inventor was also able to verify the greater efficiency of the present invention, compared with the prior devices, using the following devices: - BICOM from Regumed Lochhamer Schlag, SA; - VEGATEST EXPERT by Vega AM Hohenstein; - PROGNOS from MedPrevent GmbH &Co; - PRT 2000S from Biomeridian. The invention relates, according to a first object, to a device for protecting persons from electromagnetic waves, comprising two substantially planar loops characterized in that the two loops are substantially identical and placed opposite one of the other and electrically connected to each other by two separate bridges, the two loops being electrically isolated from each other with the exception of said bridges. In one embodiment, said loops are mounted on a flexible printed circuit and covered with a flexible insulating plate made of polymer material. Other objects and embodiments of the invention will now be described with reference to the accompanying drawings, illustrating non-limiting embodiments, drawings in which: - Figure 1 is a front view of a device according to a first embodiment, - Figures 2 and 3 are front views of two other embodiments. As shown in the figures, the device comprises two metallic wires, for example, of copper or copper alloy, these wires each forming a loop 1,2, these loops being placed opposite one another and being substantially identical in shape. The loops 1,2 are placed facing each other and electrically insulated from each other by a plastic material such as polyester, the two loops being connected to each other by two bridges 3,4, advantageously formed by the wire which also constitutes the two loops 1,2. The manufacturing of the device can be carried out as follows. In a first step, a metal wire, for example, of copper, is bent so as to form the loops 1, 2, the two free ends of this wire being welded to one another. At the end of this first step, two substantially identical loops are obtained, connected by the bridges 3,4, the assembly being substantially planar. This assembly is then placed in an insulating polymer resin and the two loops are folded towards each other before the resin hardens. Alternatively, the two loops are folded before being placed in a mold into which a polymeric material is injected. According to a particular variant, one of the two loops is substantially homothetic to the other, but slightly larger, of the order of a few percent. In the appended embodiments, the two loops each have only one turn. In other embodiments, not shown, each loop comprises at least two turns substantially placed in parallel planes. In a particular embodiment, the loops are connected to at least one capacitor, in series and / or in parallel. The device can be mounted as a jewelry, pendant, bracelet or patch, or against a watch case or plated on a mobile phone. The Applicant has found positive effects on non-objectified symptoms, since the device is worn in direct contact with or near a part of the human body, for example sewn in a garment.
