DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns a device for influencing localized low-frequency electric and magnetic fields which act on a conductive structure located within a delimited space, such as the organic structure of a living organism. Such fields are predominantly caused by high voltage power lines, railway power lines and domestic power supply lines, as well as the electric units connected thereto.
As has been known for some time that low-frequency electric and magnetic fields have a considerable influence on organic structures, and they do so by means of their effect on biological processes. One of the causes is the influence on ions within these conductive structures. In order to avoid repetition, this topic is dealt with as part of the explanation of the invention. In this context, the important feature is frequently not just the field of the fundamental wave of the fields, but also its harmonics. A spectral observation indicates frequencies referred to as concentration frequencies which are determined by the fundamental wave and the harmonics. Generally speaking, only harmonics of up to the third order are of interest.
It is an object of the invention to reduce at least to a considerable degree the effect of such fields within a delimited space and at the same time to provide a targeted effect on a substance.
SUMMARY OF THE INVENTION
This is achieved according to the invention with a device for influencing localized low-frequency electric and magnetic alternating fields which act on a conductive structure located within a delimited space, such as the organic substance of a living organism, which device has a receiving device which picks up the fields within the delimited space in the form of field components oriented according to a system of coordinates such as a Cartesian system, from which are then derived the fields used for compensating the alternating fields, by providing a measuring device that is connected to the receiving device, which measuring device is used for determining amplitude, frequency and orientation of the field components picked up by the receiving device, by providing a transmitter, comprising a device for generating a counter field in the delimited space and connected to the measuring device by means of a control element, by providing the control element, the transmitter and the device which generates the opposite field so as to be adjustable in accordance with the measured values from the measuring device in their frequencies, strengths and counter field coordinate orientations such that the counter field generated in the delimited space interferes with the localized fields in such a way as to compensate at least approximately their effects on the conductive structure. The transmitter either generates with the device for generating the counter field a further oscillation field with a frequency lower than that of the counter field for compensating the localized fields having the same concentration frequency, in particular an oscillation field with a frequency between approximately 1 Hz and approximately 8 Hz or approximately 10 Hz and approximately 30 Hz, or the frequency of the transmitter is displaced in relation to the concentration frequency of the localized fields by such a value as to cause an interference oscillation to be generated within the delimited space, whereby the interference oscillation is of a relatively low frequency in relation to the concentration frequency of the localized fields, in particular, has a frequency between approximately 1 Hz and approximately 8 Hz or approximately 10 Hz and approximately 30 Hz.
Devices for compensating disruptive magnetic fields are generally known, as are devices for compensating frequencies from the electric power supply network, for example, from DE-OS 32 07 708 A1 and DE-OS 32 09 453 A1. These devices operate three-dimensionally with respect to compensating effects and use, among other elements, Helmholtz coils. However, they lack the characteristic features of the present invention. This is also the ca
