Abstract

This invention patent in the electrical engineering, electronics and telecommunication development sector claims, in accordance with the description, a device providing a shield against radiation harmful to human health (the international opinions confirming this being mentioned in the text) emitted from cellular devices, iPhones and similar devices. The invention blocks such radiation without any negative effect whatsoever on the normal operation of the devices. Since radiation accumulates in the human body, the major problem relating to absorbed radiation is not the specific absorption rate (SAR) of the emitting devices. This specific absorption rate (SAR) is commonly used ineffectively as a solution to the problem of radiation. The document sets out references and concepts that show how this rate does not safeguard the health of users of mobile telephones, including Nokia, which sells anti-radiation headphones (which do not solve the problem). The invention described is a shield made of high-density steel or lead glass or phosphates for housing the devices. The shielding is open on the sides to enable data communication from the cell phone or the like with the telecommunication systems, and the shielding includes through-holes for the wires of the cellphone accessories, such as headphones, microphones and external keyboards. The through-holes are designed to be placed in technologically suitable locations to prevent radiation leaking through them, since they do not satisfy the essential ratio of being up to 1/10 of the wavelength of the radiation to be blocked. Ferrites or magnets are arranged about these holes to improve blocking (more necessary in the glass version).

Description

RADIATION PROTECTION EQUIPMENT GENERATED BY CELL PHONES AND

SIMILAR PRESENTATION OF THE INVENTION

The present invention is characterized by a unique, global solution to prevent mobile phone users and those around them from being harmed by the harmful radiation generated by it during the process of communicating with telecommunication centrals. The invention, in one of its options, allows the user to even use the features of 3G telephony of current mobile phones, as all the technology of IPhones. With this invention, a device that consists of a shield, which blocks such radiation, including the headphones, microphones and external keyboards attached to the cell phone. The shielding guarantees an external radiation index of less than 0.0% in mobile phones and the like and 0.0% in headphones, microphone and external keyboards attached to them. These indices were measured, obtained experimentally, with values measured with shielded equipment, compared to the maximum value transmitted by a mobile phone without protection. The shield eliminates all radiation on the phone, headphone wires, microphones and external keyboards, a solution not yet on the market.

Patent Reason

The purpose of this patent application is to prevent users of mobile phones and the like, especially children and adolescents, when receiving or sending calls, messages or any communication with the telecommunications system, from having serious health problems, including fatal, improper or excessive use of them. Such concerns also include people who are close to those who are using a mobile phone, who, like users, is subjected to health-damaging radiation.

Some people who do not use cell phones, perhaps because they know or are afraid of the harm they cause to health (we will show in this text with reliable references), nonetheless suffer sympathy for being close to those who use them. It's hard to find places where no one is using cell phones at all times. That said because there are currently 4 billion mobile phones in use (International Telecommunication Union-2009), or about 2/3 of the world's population.

When research was done until recently in 2008 about the problems arising from cell phone radiation (it was hard to believe that the planes were falling due to them), only at reputable universities could one obtain information and clearly observe the harm, several fatalities. , which cellular radiation during the communication process would cause in the medium term. Nowadays, you can get information even from local newspapers, such as the news report (http: // www. Leaflet.uol.com/sheet/informatica/ultl24u387545.shtml) where it states:

Sic ... "Cell phone astonishment should kill more than cigarettes in a few years .."

Unfortunately, this is true! ”This article cites the research of one of the greatest neurosurgeons in the world today, the award-winning MBBS BSc (Med) PhD F ACS Dr Vini Khurana (http://www.brain-surgery.net.au/ c_a.html), where you can see a full report and supporting videos about the brain tumors that such radiation will come and are already causing: "Mobile Phone-Brain Tumor Public Health Advisory" (http.V / www.brain-surgery.us /mobilephone.html).

(http://www.nossofuturoroubado.com.br/arquivos/novembro_09/radiacao.htrnl) and point to resolutions that have been filed in the world, such as in countries like: Switzerland, Germany, Israel, France, United Kingdom and Finland . The biggest evidence that radiation is a problem to be considered can be glimpsed when companies like Nokia start selling equipment, special headsets, to avoid radiation in the brain (http://alibaba.corn/product-tp). / smart-safe-hands-free-for-nokia- 106081875.html).

However, regardless of the solution adopted or not for reducing harmful radiation produced by mobile phones and the like, it is known that an older person can decide what to do with his life, as long as within the legal limits. Unfortunately, this right to be negligent affects the people next to those who are using a cell phone (almost all) who will also suffer the ill effects of radiation.

As for minors, people who suffer most physically, biologically, from such radiation (since they have the thinnest skull and brain still developing), they are increasingly adhering to the premature and inconsequential use of this technology. Whether by choice or as a gift, teens spend more time chatting with each friend or acquaintance throughout the day. This has occurred even in low income populations. Their misinformed tutors worry little about such a factor, which, according to Dr Vini Khurana, will have a brain tumor in less than 15 years of use. State of the art

Currently the mobile phone is used by the majority of the population, including children, and in most cases without concern for radiation from it, when the mobile phone establishes a communication between it and the telecommunication system (GPRS, GPS, others). .

When this concern exists, lay users' alternatives to reducing radiation exposure are usually: the headset, the Bluetooth handsets, and the speakerphone. As it is difficult to find commercial solutions to cell phone radiation in specialty stores and the formal market (few even admit that radiation is bad because it would hinder sales), caring people seek solution in informal markets where they sell illusions or illusions. solutions that do little to minimize the problem. Let's see:

Wired Headphones: An attempt to place the mobile phone further away from the user and the mobile phone.

Wired or cordless headphones using hollow tubes at their ends:

A suggestion found on some well-referenced sites, such as htφ: / hypescience.corn / 5- (hcas-to-avoid-cell-phone cracking), is to use hollow-tube headphones for the past 15 years. centimeters of the wire (where sound is transmitted through the air for the last 15 centimeters), or attached to a blue tooth (http: //english.alibaba.corn/product- ^/smart-safe-bluetoom-radiadon-free-stereo- handsfree- 107143409.html), Israeli technology, which promise to attenuate at the point of connection of the ear to the ear, at the ends, up to 98% of the total radiation.Even mega Nokia company admits the problem of radiation in mobile phones similar product (air-tube headphone), wired equipment, which can be found at http://alibaba.com/product-tp/smart-safe-hands-freefor-nokia- 106081875 .html. Ferrite cores: Another suggestion in the art of containing radiation is the use of ferrite cores to be placed on the headphone wires, where it is said to contain, block, radiation that passes through the wires, making it negligible. .

Handsfree: One of the best suggestions: Using the Handsfree feature on many phones. The speakerphone, to be effective, should be at least 2 meters from the user. Some are said to be 15 to 20 cm enough to minimize radiation by 1/16 of total radiation.

Low SAR Rate: Some people advise using mobile phones with the lowest Specific Absorption Rate (SAR) as a solution to the radiation problem.

Efficient or not the solutions can be evaluated in the following presentation, where are presented and referenced the arguments and facts that show that the state of the art in containing the problem of radiation emitted by mobile phones is flawed in all solutions cited (the most currently used).

Poor points of the prior art

The general problem with all the suggestions and solutions researched and some listed and described here, apart from the specific problems of each (cited in this topic), is that most of them are based on reducing the radiation level of the mobile phone user.

At this point, it should be remembered that radiation is a process of accumulation, that is, how much radiation a body absorbs, it will retain it.

Thus, ahead of the case of using a speakerphone at 15 cm, where theoretically it would reduce the radiation to 1/16 of the total radiation, taking into account the call time that an average teenager uses (which exceeds 15 minutes, arriving, in many cases, exceeding more than one hour), there is no point in reducing this, where the maximum usage time should be 5 minutes per week for today's most powerful and high-end mobile phones.

Thus, an efficient solution is to retain, block all radiation, or reduce levels that may be considered insignificant compared to the average life of people in countries with lower life expectancy (where there are cell phones as well). The amount of radiation accumulated also varies with the type of person and age, for example: pregnant women can only absorb doses corresponding to 30% of a non-pregnant person and adolescents only 10%, which reaffirms that it is said that protection must totally block out the radiation. Palliative solutions that only attenuate the radiation index will not be effective in the medium and long term.

Another point of relevance, not observed by existing solutions, is that for each part of the human body there is a daily, weekly, monthly and yearly limit for accumulated radiation in the period, where, for the whole body of an adult human being this dose should not exceed 5 rem (0.05 Sv), which, calculating for current phones, this index is far exceeded, taking into account only the region of the head, disregarding the rest of the body.

For now, cell phone companies have been following maximum SAR absorption per individual, having to be less than 1.6 watts per kilogram (W / kg). Again, even obeying this standard and indices, it is forgotten that the absorption index is important, but, most importantly, is the time of use. It is no use having a SAR phone that is within the standards, or even lower if a person uses the phone for a long time. Absorption time is the deciding factor in the physical damage that accumulated radiation will cause to users and people near mobile phones.

Following are some deficient points of the prior art of the options cited earlier in this document.

Wired Headphones: Because cell phone wires are metallic and good conductors of magnetic fields, they carry cell phone radiation, pass through the wire microphones, and concentrate them on the earphones, as shown in Figures 2 and 3. of the item Figures. The measurements were made by the development team of this invention in the laboratory (whose photos are in the figures mentioned), showing that a good part of the radiation (at least ¼ of the maximum value emitted by the cell phone) is concentrated in the headset speaker.

Hollow Tube Headphones - The big problem is that even attenuating the point of contact with the ear, there is still radiation in the blue tooth receiver (Figures 3 and 5) around ¼ of the total radiation, which will still be close to the body of the mobile phone user. If you use wired headphones, you still have radiation on the wire to the junction with the air tube. Added to these problems, shortcomings, the cell phone without protection will continue to propagate harmful radiation when near the user or anyone else.

Ferrite Beads - Those who encourage the use of ferrite beads in the headphone wires to contain radiation, even claim to contain radiation entirely in ferrites (which would absorb the full radiation). In the case of ferrites, in addition to leaking some radiation, such a solution, to have some efficiency, requires being stretched wires away from the cell phone (which continues to emit harmful radiation). Unfortunately, most people put their cell phones in their hands, bags and close to their bodies, forgetting about the risk and damage that radiation will cause them over time.

Loud Voice- With increased power and consequent absorption rate

Specific Absorption Rate (SAR), it cannot be guaranteed that using the hands-free mobile phone 15 or 20cm away from the user, reducing 1/16 of the total radiation, will be a safe distance to avoid health problems. Two meters would be a reliable value for negligible radiation (difficult even to measure). Another problem with the use of handsfree, and serious, is that its use eliminates all the privacy of conversation, and annoys others in the same environment.

Low SAR - (Specific Absorption Rate) - As small as a cell phone's SAR is, it is sufficient to generate the harmful health cited in this document. SAR is an important factor, but what really causes health problems is the user's exposure to radiation.

Bluetooth- As already stated, in the search for palliative solutions, the headset with Bluetooth technology are widely used. This is mainly due to a number of poorly based information distributed on the internet, where, for example, they say that bluetooth headsets have only one-hundredth of a cell phone's radiation (which we show to be untrue in figures 4 and 5 in this text). Our measurements proved that bluetooth reduces radiation by 1/8 of total radiation. This rate, for those who use the cell phone intensively (most cases in teenagers and business people) means a great health risk, as time is the worst factor in mobile phone use. Unfortunately bluetooth headsets, even with low radiation, are not effective to prevent the user and those close to him from being hit by the radiation generated in the process, especially if the cell phones are close to them (in reality will always be near someone, ie someone will be within range of your radiation). Figures 1 to 7 of this text show illustrations with situations of use of these processes, associated with radiation measurement photos in each case. It is already noted that the solutions do little or nothing to prevent the health problems that will eventually arise from the absorption of such radiation.

Thus, several suggestions and ineffective solutions, even citing people of recognition, can be observed around the world, for example: in htφ: // hyt) escience.con 5-dic-B-para-e \ dtar-a -radiação-do-phone-e-cellphone / e http://www.nossofuturoroubado.com.br/files/november_09/radiacao.html.

Thus, the phones and other current solutions against cell phone radiation (there are several others, some inefficient, or unworkable), only facilitate mobility in the use of mobile phones and little protect users from radiation.

Objectives of the invention The protective equipment object of this patent has as its main object to contain all harmful radiation generated by the mobile phone within a shield that avoids subjecting the mobile phone user and the like to be hit by it (the radiation), even if it uses Wired headphones.

In the pursuit of these goals, blocking harmful ionizing radiation to the human body, aims to maintain all the versatility and mobility of the cell phone, regarding talking and receiving calls, as well as information exchange between the cell phone and telecommunications system.

This invention aims to introduce in the state of the art, in the welfare of society, in the health of all people, active or passive users of cell phone radiation, a possibility of being able to use cell phones anywhere, maintaining their potential without, Doing so may cause harm to the user and those around him or her, ie in the range of the radiation. Radiation is cumulative in the human body, having no cure since its discovery in the short or medium term. Detailed Description of the Invention

The invention is to construct a protective cover that blocks harmful radiation from the cell phone without blocking the signal necessary for its communication with the system. (GPRS, GPS, etc.). In addition, it must allow the communication of the mobile phone with the user other than just by speakerphone.

In this invention, for the mobile phone user to be able to use it to communicate with the world, he must do this through a microphone headset, custom made by each mobile company.

Although it seems contradictory to the analysis done in the art, the use of the wired headset is the option that makes the solution viable to communicate using the cell phone, without having the harm caused by the radiation produced.

For this, the headset is connected to the mobile phone and its wire will come out of the shield through a hole in it, where the shield, the protective cover (in the form of a wallet or a picture frame), is in charge of not allowing any radiation out through the wire, only the electrical signal that will power the headphone speaker.

This factor brings an extra benefit to the invention, where the headphone and microphone signal translates into an improved discrimination of the words spoken and heard on the cell phone, since the radiation produced, now blocked, no longer interferes with the signal. (electrical) audio that will power the headphones and microphone.

The present invention is committed, assures the user that no harmful radiation will leak from the cell phone (values below 0.0%) and from the headset (0.0%) (Figures 6 and 7).

This protective cover is made of a high density steel plate with equally spaced holes on its surface with a 1/10 wavelength diameter of the mobile phone's frequency. Thus, such holes of such diameter represent a high impedance for the microwaves, preventing leakage in the shield, reducing also currents and parasitic fields in the shield.

These diameters, therefore, should be smaller than 1/10 of the wavelength of the highest frequency currently used in mobile phones, predicting the increases that may occur (as they have occurred) in the short and medium term.

Currently, for safety, we are designing and testing for 2450 MHz wavelength, so we take advantage of the experience already established in good microwave ovens, whose frequencies are already close to those of mobile phones.

In the construction of the shield, it is foreseen to use a toroidal magnet placed around the hole (Figure 8) through which the earphone wire passes, in order to avoid radiation leaks through the hole. Due to the constructive process of the place where the hole is made in the shield plate, the prototype measurements were made, with the powers and SAR of the current cell phones, the use of the magnet has not been necessary.

This is because, in the shield architecture, the hole placed away from the headphone wire connection to the mobile phone is placed. This way, the cable, after the connector, has to pass an area of the shield, being absorbed by it. Even so, with the increasing power of mobile phones, this solution is foreseen in this patent application, so as to retain the protection of this increase when necessary.

Looking at figures 6 and 7, without the use of the magnet, it can be seen that the radiation is not leaking, ie it is being contained by the shield even without the use of the magnet.

So, in short, the use of magnets is foreseen if, in the future, with higher-powered cell phones, there is no radiation leakage through the holes in the earphone wires. At first, the current parameters will not be necessary, but industrial protection is already required for such a solution.

The shield is not fully closed. At the ends there is no shield to allow the cell phone to receive and transmit the communication signals with the telecommunication centrals. Even so, the radiation generated in the communication process, which is the harmful one, is totally contained. Because the phone is placed completely inside the protective cover, with the cover exceeding the size of the mobile phones, the generated fields are retained internally.

The invention initially suggests three initial versions: the wallet type (Figure 6), the frame type (Figure 7) and the pyramid type (Figure 10).

In the case of wallet type, you can put the phone with the protection in pouches, bags and even hold it during a conversation (preferably not by the edges). The radiation outside the shield is zero (Figures 6 and 7).

In the case of the frame version (Figure 7), the phone is placed behind the shield (Figure 8), the phone with the plate parallel to the user, blocking direct radiation. In this case, some radiation leaks behind the shield, and the frame should be placed in places where there are no people behind and very close to it, such as on a bookcase or table against a wall (partition does not block radiation sufficiently). ).

This solution, picture frame or calendar door, is attractive because it allows the user to have several shielded picture frames, placed at home, office, ... as well as in public and private companies, which can put these shields in special places so that their customers can talk on their cell phones without causing collateral damage to others present and to themselves. Something similar to existing smokers' locations, except that in this case, not even the user will be affected by the radiation from their mobile phone.

In the case of companies and offices, as it can not be foreseen to use a single type of mobile phone, and for hygiene reasons, each user should take his phone and put on the shield. This means that the hole must be larger to accommodate all types of handsets. In this case, the use of the magnet around the hole is necessary (figure 8).

The pyramid-shaped structure (figure 10) also doubles as a picture frame or calendar holder. It is also geared towards environments where there is a possibility of having people in front and behind it, and thus the shield must protect both sides of it. The difference between these last two structures is only in the material cost. The Working Principle is the same. In these pyramids you can even leave entry for a cell phone on each side, allowing the simultaneous use of it by two people. An attractive solution for places to be made available for use in public places, businesses, and the like.

In addition to these three configurations, patent protection is also required for any arrangement or any alteration that may occur to the radiation shielding, as the shape would add nothing technological to the subject matter of this patent. The invention is summarized in building a shield that contains all the radiation generated by the cell phone, preventing it from reaching the user and those close to him, regardless of its shape, using a wired headset. The shielding configuration integrated in the manufacture of a mobile phone case or the like is also the subject of this patent. In this case, all the circuits that are responsible for the radiation generation would be inside the shield, covered, wrapped, by the cell phone cover, leaving the interface accessories (display.keyboard, speakers, etc.) outside the shield, as these do not produce harmful radiation.

The use of a toroidal ferrite around the hole in the wire, inside or outside the shield, is also under the request of the industrial protection, as it would have a similar effect to the placement of the magnet mentioned above. In addition to this shield, the operation of the mobile phone will be accomplished through the headset and microphone designed by the manufacturer of each mobile phone, whose connection must be inside the shield and that the headphone / microphone output hole is not located directly on the connecting the handset connector to the phone (or similar). This prevents radiation from escaping through the hole, which at this point will be well over 1/10 of the wavelength of the cell frequency (diameter whose value ensures that the hole's reluctance will be high enough to prevent leakage). The earphone wire passing through the shield, in its length, until it exits the hole, has the field concentrated in the same (in the wire) captured and retained by the shield, leaving the shield, in the wire, only the audio signal (which improves the phone audio sound or similar).

Accordingly, any change of form that utilizes such principles will be covered by this application for industrial patent protection.

Patent-relevant aspects of the use of cellular and related equipment, with and without shielding, presenting generic shielding and in three basic formations

Nine figures are presented in the Figures of this patent application in order to clarify the need, use and innovation of the shield. Following are the comments of the nine figures presented.

This value will be used to calculate the percentage of the other measurements in the following figures, where, for example, a measurement whose value equals 0.8 would mean a radiation of ¼ (25%) of the maximum radiation (3.2) of this equipment. FIGURE 2 - The headset (4) transmits at least 1/4 of the radiation from the cell phone to the head (A), concentrating the radiation on the wire (4). The body (2) receives radiation from the cell phone (3) if it is close.

This Shield has holes in both sides of the pyramid, allowing more than one user to use it (placing more than one cell phone inside the pyramid). The red arrows indicate the absence of radiation (B) in two directions parallel to the users.

Claims

"EQUIPMENT FOR PROTECTION AGAINST RADIATION GENERATED BY CELL PHONES, IPHONES AND SIMILAR PHONES" In this patent application, the industrial protection of equipment, a shield, is characterized by being unique in the results it presents.

These results focus on protecting against radiation emitted by mobile phones and accessories to users of this technology, as well as to those nearby.

The protection acts against the radiation emitted by the cell phones and assistants during the communication process, while maintaining all their functionality. The shielding, which is the subject of the patent application, blocks radiation from mobile phones and earphones (wired), resulting in a reduction of the radiation emitted in the communication process by less than 0.0% of the total radiation emitted by the unprotected cellphone. (which can be regarded theoretically and practically as negligible).

The results are unique because radiation absorbed by the human body is cumulative, and in this invention, radiation from cell phone and accessories is completely eliminated (less than 0.0% of cell radiation), so there is nothing left to accumulate.

The patent for high density steel shields having holes less than 1/10 of the wavelength of the cellular frequency and the like, containing a hole or more holes in the frame capable of passing the wire connectors of the cell phone headsets, microphones, keyboards, and accessories therefor, or around this hole, a magnet or ferrite may or may not be placed to prevent radiation leakage in these holes greater than 1/10 of the wavelength of the cell phone. , IPhones or the like.

A patent for shields made of Glass is claimed.

Lead (used in X-ray rooms and special glasses) and Phosphate glasses developed by 1PEN (Institute for Energy and Nuclear Research-Brazil). These types of glass also block the radiation emitted by cell phones and the like, and, being transparent, allow the user to use cell phones, IPhones and the like, even for the existing multi-media functions from the 3G technology of TV, Internet, others. . A patent is also claimed for all configurations, structures, architectures and shapes of these shields applied to the same purpose in mobile telephony. It is also claimed the option of inserting extra holes (could have only one), to pass the connecting wires of the external keyboards of the cell phones, and the like, and other accessories, mainly in the glass shield version. against radiation. This measure enables the use in shielding by modern IPhones and mobile phones with 3G, internet, TV, etc. This ensures that the shielding of this patent application protects the user against radiation from the wires of keyboards, headphones, microphones and other accessories.

The claim therefore encompasses any type of structure, architecture which will implement the same functionality as this patent application, as described above, in addition to the wallet, picture frame and pyramid structures, whether steel or glass, with or without imàVferrite.

Radiation is not leaked through these wire holes through magnets / ferrites around the holes (Figure 8). Another technological, strategic measure that avoids radiation leakage through the wire holes is the location of the holes, which should not coincide with the connection point of the cell phone connector and the like, forcing the wire to go through a strip of the shield. such that it blocks radiation from it before passing through the holes.

A patent is also claimed for the rights of this shield in the possible and future construction of cellular telephone equipment and purposes which are assembled using the technology of this application for industrial protection, that is, rather than placing the equipment in it. shielding and using external peripherals whose wires are shielded from radiation blocking, new two-layer cell phones and the like would be created, namely:

• The first layer would contain the equipment circuits that generate radiation at the time of communication. This layer would be covered by the shield, or even the shield would be internal to the circuit cover, in no way disrupting the aesthetics of the equipment.

· The second layer would be a new cover containing the peripherals (as they are today, with sliding keyboards, covers that open and close or rotate, etc ...), unlike the technology of holes with or without magnets / ferrite, for prevent radiation from reaching the user. In this case, one would not even need to use headphones as all the peripherals would be in the second radiation free layer.
