Description

DEVICE FOR PROTECTION AGAINST ELECTROMAGNETIC RADIATION

TECHNICAL FIELD The invention relates to a device for neutralising the negative effects of electromagnetic radiation.

In a second aspect, the invention also relates to a method for eliminating or reducing the negative effects of electromagnetic radiation. PRIOR ART

Electromagnetic radiation (EM radiation or EMR) is a naturally occurring property of electromagnetism. The electromagnetic spectrum is composed of different types of electromagnetic radiation, including visible and non-visible light. Certain types of electromagnetic radiation are more harmful to biological tissues than others. The effects of electromagnetic radiation on these living cells are influenced by the power and frequency of the radiation source. Currently, the World Health Organization (WHO) classifies some types of electromagnetic radiation as a Group 2b carcinogen, meaning that exposure to this radiation is 'potentially carcinogenic to humans'.

The proliferation of mobile phones has generated a lot of interest in this field of research, as these mobile phones emit electromagnetic radiation in the microwave range of the electromagnetic spectrum. Subsequently, a number of scientific studies were set up to investigate the thermal, non-thermal, absorption and various other effects of long-term exposure to such radiation. In theory, children / young people have the potential to be at greater risk than adults of developing cancer from mobile phones. Their nervous and other body systems are still developing and are therefore more vulnerable to factors that can cause cancer, such as exposure to the field of the radio-frequency radiation emitted by mobile phones. In addition, children have the potential to accumulate more years of mobile phone exposure than adults.

Exposure to electromagnetic radiation has increased in recent years. This is mainly due to the increasing use of wireless networks, including these mobile phones. In addition, this radiation is also caused, among other things by WiFi (wireless internet), baby monitors or other wireless devices, microwave ovens, anti-theft or identification systems, fixed transmission masts for mobile phones, 3G, 4G, radio, television, high-voltage lines, transformer cabins and more. US10028539 describes garments that protect the wearer from this radiation, comprising a metallised fabric with one or more conductive metals. This metallised fabric can be used, for example, for a jacket pocket in which an electronic device is placed, so that the wearer is protected against the radiation of this device.

US6219419 describes a shielding sticker for use on a mobile phone against electromagnetic waves generated by the phone that adversely affect a person using such a phone. For example, the sticker can be used on the part of the phone that is held against the ear.

US5796335 describes a security foil which comprises a shielding against electromagnetic radiation from inside and outside, and preferably consists of a metal grid with defined grid distances. This security foil can be used, for example, to shield electrical payment transactions.

These prior art articles are not suitable for protecting the environment outside the directly shielded surface, in other words, they do not shield the surrounding environment around the article from electromagnetic radiation beyond their own physical range.

The present invention aims to solve at least some of the above problems or drawbacks. The object of the invention is to provide a device and method which overcomes at least these drawbacks.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a means for preventing the harmful effect of electromagnetic radiation.

Unless otherwise defined, all terms used in the description of the invention, including technical and scientific terms, have the meaning as commonly understood by a person skilled in the art to which the invention pertains. For a better understanding of the description of the invention, the following terms are explained explicitly.

In this document, 'a' and 'the' refer to both the singular and the plural, unless the context presupposes otherwise. For example, 'a segment' means one or more segments.

The terms 'comprise', 'comprising', 'consist of', 'consisting of', 'provided with', 'include', 'including', 'contain', 'containing', are synonyms and are inclusive or open terms that indicate the presence of what follows, and which do not exclude or prevent the presence of other components, characteristics, elements, members, steps, as known from or disclosed in the prior art.

Quoting numerical intervals by endpoints comprises all integers, fractions and/or real numbers between the endpoints, these endpoints included.

In a first aspect, the invention relates to a device suitable for neutralising the negative effects of electromagnetic radiation, wherein the device is internally provided with a grid, characterised in that the grid consists of at least two sub-grids, wherein each sub-grid comprises one or more bars, and wherein the sub-grids are positioned such that the corresponding bars of each sub-grid at least partially overlap each other.

In this context, 'overlap' means the partial coincidence in the longitudinal direction of the bars.

In one embodiment, the bars are rectangular. In another embodiment, the bars are triangular. In another or further embodiment, the bars are provided along the circumferential side with one or more notches, recesses, constrictions or protrusions. The bars may also have cut-outs on the surface such as circular, rectangular or polygonal openings.

In a further embodiment, the bars within a sub-grid may be a combination of the shapes as described above. In one embodiment, the bars are connected by a grid bridge that contacts at least a portion of the bars. In a further embodiment, a grid bridge makes contact with each bar.

In another or further embodiment, the grid bridge is positioned perpendicular to the direction of the bars. The grid bridge can also be positioned at an angle to the bars. In another or further embodiment, the grid bridge may be interrupted or uninterrupted, in other words consist of one part or more than one part. The grid bridge and/or the parts of the grid bridge may differ in width, and possibly change width along its length. The grid bridge can also be provided with one or more notches, recesses, constrictions or protrusions. In addition, the grid bridge may have cut-outs on the surface such as circular, rectangular or polygonal openings.

In a preferred embodiment, the grid bridge is connected at each end to a grid connector. The grid connector has the optional function of connecting the grid lying within the device to the outside world. This provides the possibility of connecting the grid to electrodes, electrical / magnetic contacts, information chips and also offers the possibility of establishing direct or indirect physical contact.

In a preferred embodiment, the device is externally provided with figurative images. Such figurative images can be freely chosen. In a non-limiting embodiment this concerns a twelve-loop symbol and/or an Atlantis symbol. Preferably, the grid will consist of a conductive or semiconducting material. This conductive material can be any material that transmits electrical current and shows a low resistance. All metal conductors are such. The best conductors are those with the smallest electrical resistivity, such as silver and copper, because their only valence electron travels through the crystal lattice almost like a free gas, but aluminium is also a good conductor. A semiconductor is a conductor in which the conductivity is not large, but it is temperature-dependent, and in which the conductivity can be influenced by means of doping, i.e. the addition of impurities such as other metals. In a preferred embodiment, the device is a card, a ball, a cube, amulet, an item of jewellery, a garment, a decorative item or a piece of furniture or it is incorporated into a card, a ball, a cube, amulet, an item of jewellery, a garment, a decorative item or a piece of furniture. An 'amulet' in this invention refers to an object that brings good luck or protects its wearer from negative forces, effects or environmental elements. A 'card', 'ball', 'cube', 'item of jewellery', 'garment', 'decorative item' or 'piece of furniture' in the present invention refers to any card, ball, cube, item of jewellery, garment, decorative item or piece of furniture that conforms to the features of the device according to the present invention or refers to any card, ball, cube, item of jewellery, garment, decorative item or piece of furniture in which this device can be incorporated. As a non-limiting example, an item of jewellery can be a necklace, which comprises the device of the present embodiment and thereby neutralises the negative effects of electromagnetic radiation on the wearer of the necklace. As a non-limiting example, an item of jewellery can be a collar for a pet, which comprises the device of the present embodiment and thereby neutralises the negative effects of electromagnetic radiation on the wearer of the collar. As a non-limiting example, a garment can be a T-shirt, which comprises the device of the present embodiment and thereby neutralises the negative effects of electromagnetic radiation on the wearer of the T- shirt. As a non-limiting example, a decorative item can be a flower pot or vase, which comprises the device of the present embodiment and thereby neutralises the negative effects of electromagnetic radiation on a plant or flower. In another non limiting example, a piece of furniture can be a chair, which comprises the device of the present embodiment and thereby neutralises the negative effects of electromagnetic radiation on the person sitting in the chair or standing next to the chair, or on a pet or plant next to the chair.

In another aspect, the present invention relates to a method for eliminating or reducing the negative effects of electromagnetic radiation, by means of a device according to any of the preceding embodiments. For this purpose, the device is placed in the vicinity of the organism to be protected.

The invention will now be described in more detail with reference to the following non-limiting examples or figures.

EXAMPLES

The invention will now be further explained on the basis of the following example, without however being limited to this.

Example 1: Germination of cress seeds

This example relates to an experiment wherein each time two jars with 9 cress seeds each were placed on a moistened cotton pad under standardised growing conditions. The influence of the electromagnetic radiation from a wireless telephone, a Digital Enhanced Cordless Telephone (DECT), on the germination of these seeds was tested. For this, the seeds were placed in three different situations. The seeds were alternately placed next to the phone 24h and away from the phone 24h in each situation. A background electromagnetic radiation of 86.7 V/m was measured at the location away from the telephone, and a radiation of 2780 V/m at 5 cm from the wireless telephone.

In the first situation, a device according to the present invention, in particular a card, comprising a grid, comprising two sub-grids, positioned in the opposite direction of each other, each with 5 bars each having a length of about 2.5 cm, according to present invention, was placed between the two jars with seeds. In a second situation, the same device, but without a grid, was placed between the two jars with seeds. In the third situation, no device was placed between the two jars with seeds.

The results of seed germination after n days are shown in Table 1. After six days, only 11% of the seeds without device or the seeds with device without grid have germinated. The seeds in which a device with grid was placed had a germination rate of 50%. These results show that the device with grid according to the present invention protects the seeds from the negative influence of the electromagnetic radiation emitted from the wireless telephone. A placebo situation, in which only the device, but without the grid, is placed next to the seeds, did not provide extra protection for the seeds.
