Definitions

  • the invention relates to a device for recording and processing radiation emissions from technical high-frequency sources with a ring antenna pickup, furthermore a method for recording and processing interference fields and interference beams as emissions from technical high-frequency sources with a ring antenna pickup and a measuring circuit.
  • the measuring devices should be designed in such a way that they influence the existing field as little as possible. Reading out the measurement results should be possible via an optical interface. In this way, an influence on the field by the operating personnel or a risk to the operating personnel can be excluded.
  • the measuring devices should have the largest possible dynamic range, since the range of the existing and expected limit values is very large.
  • the probes consist of one or more E-field or H-field sensors with downstream rectifiers. The output voltages of the rectifiers are sent to the basic device, where they are processed.
  • One of the monocontrollers also handles the processing of measured values.
  • the voltage values U ADC sampled by ADCs are read into the processor every 400 ms.
  • the characteristic curve equation is calculated for each measuring channel.
  • the substitute field strength is calculated from the individual spatial components of the field strength.
  • the rms value averaged over the last 6 minutes (AVERAGE), the greatest field strength value since switching on (MAX) and the largest mean value since switching on (AVERAGE & MAX) are calculated from the current replacement field strength.
  • the current or averaged measured value can appear in the numerical display.
  • the current measured value is always shown in the display. It is a logarithmic level display with a resolution of 3.01 dB and a right-hand stop shortly before a possible overload of the device.
  • the units V / m, A / m, W / m 2 and mW / m 2 can be selected for the numerical display.
  • the conversion is based on the assumption of a flat wave in a vacuum.
  • the bidirectional, serial optical interface is used for remote control of the device and for reading the measured values on an external computer. This also enables measurements where it is not permissible or possible for operating personnel to be near the probe. In addition, the optical interface makes calibration of the device considerably easier. "(End of quote)
  • the best known standard value is the so-called thermal immission limit. This is around 41 to 59 V / m for mobile communications.
  • the lowest measuring sensitivity is usually 1 V / m, rarely 0.1 V / m. This means that the device manufacturers are about 100 times lower than the official limit values.
  • the second approach is that of "electrobiologists”. Today, the professional branch should rather be “bioelectronic engineer”, since many biological processes come very close to those of electronics.
  • the new invention is based on bioelectronic sensitivity (BES): a search is made for parallels between the biological processes or regulations and the technically generated interference fields and interference pulses.
  • BES bioelectronic sensitivity
  • the new invention is based on the solution shown in WO 00/29859 and supplements the older solution in some areas, which is why WO00 / 29859 is explained as an integral part of the present application.
  • This shows a procedure for the practical measurement or house measurement of technical interference fields in relation to the living environment, in particular humans, animals and plants using battery-powered measuring devices, preferably with digital display, characterized by the following features: a) the interference-effective field is measured by a voltage (in Volts, mVolt, // volts), wherein b) the antenna voltage and at least one additional disturbing parameter are determined in the high-frequency range.
  • the optimum antenna voltage is determined via a high-frequency receiver and that the at least one additional interference-influencing parameter is the type of signal technology and / or the magnetic field component and / or the specific ELF frequencies and / or the respective peak values of the ELF frequencies, be it figuratively or acoustically.
  • WO00 / 29859 started from the discovery of surprisingly strong magnetic field agglomerations, the so-called hot spots in rooms. It has been suggested.
  • the inventor proceeded from the following three findings, according to which the body's own bioelectronics and their potential for interference must be the starting point and standard for any measuring activity, especially with regard to cyclical processes, especially if a biological process is regulated by changing or reducing and increasing the pulse frequency becomes.
  • the body tries to optimally adapt a large number of processes, such as heart rate, active and passive brain activity, fast or slow nerve transmission, cell metabolism, to the current need (rest / movement) through the pulse rate.
  • Voltage fluctuations of the body's own functions It is known from medical literature that within the framework of body functions, voltages in the range from a fraction of a millivolt (mV) to 100/200 mV prevail.
  • mV millivolt
  • the question of the penetration depth and the magnetic field Apart from the frequency / pulse question, the question of the penetration depth is absolutely central. If external radiation with interference pulses cannot penetrate the brain, it is not necessary to influence the brain.
  • a) Thermal model In the thermal model, a piece of meat serves as a model. The whole piece of meat is irradiated with the piece of meat and the temperature is measured in layers inside the piece of meat. The result is a curve for the penetration depth of the radiation in the meat portion and a second for the fat portion. The result can be reproduced and confirmed in every laboratory in the world. This method is quite plausible if only the heat effect of the radiation is of interest as a criterion.
  • Athermal model In the athermal or non-thermal model, as can be seen from the literal sense, no temperature change can be measured. The question of the penetration depth is already answered in the case of microwave beams by physics, namely the formation of magnetic field agglomerations. The primary measure is the magnetic field component. This penetrates the human body almost without obstacles and with it the entire information of the microwave transmission technology.

You get the load situation or the load history over a whole day at a glance. 0-100 kHz, preferably 0-10 kHz, and 10 kHz to 20 GHz are recorded as the low-frequency range.

Abstract

L'invention concerne un procédé et un dispositif permettant d'enregistrer et de traiter des champs parasites et des rayons parasites, en tant qu'émissions émanant de sources haute fréquence techniques, avec un capteur d'antenne circulaire et un circuit de mesure. Un nouveau procédé d'enregistrement de mesure permet pour la première fois, d'analyser avec précision, outre l'intensité de champ d'une émission haute fréquence, avant tout également tous les critères significatifs des effets basse fréquence, notamment ceux compris entre 0 et 100 Hz, et les effets de champ en dessous de 0,1 V/m, et par ex. de détecter les fréquences parasites à action cérébrale et cardiaque. Les signaux enregistrés par un capteur d'antenne circulaire sont traités par l'intermédiaire, dans chaque cas, d'une diode à sens de blocage opposé, avec la ligne de signalisation correspondante, et les deux lignes de signalisation sont reliées après la sortie des diodes à un dispositif de mesure, par l'intermédiaire d'un condensateur. Selon une seconde variante, le capteur d'antenne circulaire comporte plus d'un tracé conducteur, lesdits tracés conducteurs étant disposés de préférence de manière concentrique et annulaire. Les signaux enregistrés par les tracés conducteurs sont traités avec un réseau de résistances par l'intermédiaire d'au moins deux lignes de signalisation reliées à un dispositif de mesure.
