Description

Technical field

The utility model relates to the field of mobile communications, and specifically to the device of mobile phones, the design of which provides a significant reduction in the harmful effects of radio-frequency radiation on the human body.

Mobile communications are characterized by rapid development, ever-increasing volume of use, active penetration into all countries of the world. In October 2009, at a meeting of the State Council on issues related to the development of communications, Russian President Dmitry A. Medvedev presented data from which it follows that currently in Russia there are 140 mobile phones per 100 inhabitants. As follows from sources [1, 2], more than one sixth of the world's population used mobile phones during the study period, and by the end of 2004, more than a billion subscribers from more than 200 countries had used mobile phones.

The dynamic development of mobile communications is characteristic not only for the volume of their use, but also for constructive improvement. First-generation mobile phones, which appeared in the 80s of the last century, used analog technology that allowed only the transmission of an audio signal. The second generation, starting in 1991, was already based on digital technology, which allows the transfer of not only data, but also images. Finally, the third generation, which currently represents the market, allows the use of a significantly expanded registry of additional services, such as facsimile communications, e-mail, and Internet access.

It is known that the basis for the functioning of mobile communications, both analog and digital, is the reception and transmission of a signal in the form of waves in the high-frequency (HF) (analog signals) and microwave (microwave) ranges of the electromagnetic spectrum. High-frequency signals are not ionized radiation with a wavelength in the range from 3 KHz to 300 MHz, and microwave waves are from 300 MHz to 300 GHz. The frequencies used by mobile phones and their base stations are in the range from 900 MHz to 1.8 GHz and up to 2.1 GHz.

Despite the triumphal march of mobile communications around the world, public concern is growing to the same extent about the effects on the health of users of mobile phones of electromagnetic fields generated by both the mobile phones themselves and the base stations that ensure their operation.

Since 2000, reports appear that present the results of studies and summarize existing knowledge about the effect of mobile phones on the health of users, while mainly from the point of view of the generally recognized carcinogenic effects of RF and microwave energy.

Experimental studies of the biological effects of exposure to RF and microwave fields are carried out on a large scale in various countries, where the use of mobile phones is the most common and long-lasting. These studies, as follows from sources [3, 4], include studies on volunteers, animals and in vitro, cellular methods and cover the influence of HF and microwave radiation in the range of 100 MHz - 60 GHz and are considered as functional changes in the brain (effect the effects of RF and microwave fields on the head), as well as carcinogenic processes, reproductive function and development, the cardiovascular system and longevity (as a result of exposure to RF and microwave fields on the whole body).

The revealed biological consequences for the cardiovascular, endocrine and immune systems and the behavior of the studied animals, according to the researchers, are the consequences of the thermal effects of acute RF and microwave radiation, because in order to cause such effects, it is necessary to increase the temperature by at least one to two degrees Celsius. Regarding the increased risk of developing cancer due to exposure to RF and microwave fields, evidence of such a relationship is extremely unreliable. The researchers explain this by the fact that the radiation of mobile phones and base stations does not have the energy sufficient to directly break the chemical or molecular bond, i.e. for DNA damage. In addition, the prior art does not know the biological mechanism of the occurrence of possible carcinogenic effects of RF and microwave fields. However, the researchers believe that although the mentioned mechanism is currently lacking, nevertheless, one should not reject the harmful effects of these fields on human health.

Studies regarding the risk of developing a brain tumor have yielded mostly negative results. The fact is that in order to identify the effect of mobile phone radiation on the brain, a follow-up period of at least 10 years is required. In published sources, this period was 8 years, of which the first half of this period observed people used mobile phones based on an analog signal. Therefore, the researchers argue that no signs of an increased risk of developing brain tumors when using a mobile phone for less than 10 years have been found. However, increased risks of developing auditory nerve neuroma were identified after 10 or more years of using a mobile phone. At the same time, in a number of publications recently, where observations exceeded the 10-year period, researchers more confidently argue that there is a negative effect of radiation from both the mobile phone itself and the base stations. In this regard, it is recommended that researchers adopt a precautionary approach — that is, limit exposure to RF and microwave, plan the location and configuration of base stations, and encourage selective use of mobile phones. More categorically, it is recommended to limit the use of mobile phones by children. Natural is the fact that serious, in-depth research on this issue, obtaining objective information, is prevented by powerful corporations that are developers and manufacturers of mobile communications.

State of the art

Irrefutable evidence of the negative impact of mobile phone radiation on the user's health are technical solutions aimed at reducing this effect, representing the prior art. The analysis of technical solutions representing this topic in the prior art shows that they are divided into several areas. As one of the technical solutions, which is the direction associated with the direct shielding of the radiation of a mobile phone, you can specify a mobile phone with a device to reduce the intensity of radio exposure to the user, in which on the back of the phone’s body directly behind the antenna, a screen having an absorbing coating of radiation is strengthened, this screen can be made folding or fan-shaped articulated petals, one of which is fixed fixed to the connected axis telephone housing and the other mounted on the pitch axis rotatably, wherein the other extreme petal associated with the axis of the torsion spring, and the petals are made vyshtampovki different diameters, which are in a folded position to another screen [5].

Shielding can be carried out either directly by introducing a special element acting as a screen into the design of a mobile phone, or by using, for example, the housing of a mobile phone. A representative of this direction can be considered a device for protecting the handset of a cell phone from electromagnetic radiation, in which that protect a person from radiation, are the surfaces of a cell phone facing the person, a ferromagnet introduced during manufacture powder [6].

Also known is a mobile phone, including a housing made of dielectric material, a radio transmitter, a power source, an electromagnetic radiation generator of the millimeter wave range with a power of 10-30 μW, with a flat slot antenna that is connected to a power source and located in the immediate vicinity of the sound reproducing device on the inner side of the housing wall facing the user, so that the millimeter-wave electromagnetic radiation produced by the generator is ln had an impact on the user's earlobe, while a fragment of the telephone body covering the electromagnetic radiation generator of the millimeter wavelength range and a flat slot antenna was made in the form of a dielectric plate with a refractive index of 2.1-2.4, and the plate thickness being determined ratio:

where h is the plate thickness, mm;

n is the refractive index of the dielectric;

m is a natural number;

λ is the wavelength of electromagnetic radiation in the millimeter range, mm;

σ is the correction in the range 0.13-0.17 mm [7].

An analysis of the above technical solutions representing the prior art in this field, using shielding to reduce the harmful effects of radio frequency radiation, shows that they are characterized by at least one significant drawback. As you know, any shielding affects the shape of the lobes of the radiation pattern, deforming it significantly, which affects both the shielding efficiency and the quality of the work of mobile devices. It is very problematic to achieve a technical result by introducing an additional electromagnetic radiation generator into the design of a mobile phone, the effect of which on biological active points concentrated in the user's earlobe helps to neutralize the harmful effects of decimeter-wave electromagnetic waves on a user. The fact is that the biologically active points for each user are purely individual, very peculiar physiologically, and their response to the effects of electromagnetic radiation of the millimeter range for each user is poorly predicted.

The closest in technical essence to the claimed utility model and the technical result achieved in the process of using it is a radio communication device comprising a housing in which blocks and nodes are connected to a wireless message reception and transmission system, including a short-distance receiver-transmitter, the main a transceiver connected to the antenna, a radio signal processing unit, coupled to the main processor and both transmitter-receivers, a memory unit with programs for implementing a radio communication device associated with the main processor, information input and display means including an information input unit, a microphone, a speaker, a display connected to an audio processor, a photo-video camera, a power supply unit including a charger connected to a power battery, which respectively connects all the blocks, nodes and means of the radio communication device [8].

The technical solution disclosed in this application for an invention filed with the US Patent Office is characterized by a special housing design that can slightly reduce the effect of radio emission, however, its value remains very significant.

It is known (Guidelines MUK 4.3.043-96, Goskomsanepidnadzor of Russia, Moscow, 1996) that the power flux density (PPM) of the electromagnetic field of radio facilities operating in the frequency range 700 MHz-30 GHz is determined by the following relationship:

where: P is the power at the input of the antenna-feeder path, W;

G is the antenna gain relative to the isotropic emitter, determined in the direction of maximum radiation;

P _aft = P _o · P _t - loss coefficient in the antenna-feeder path;

P _o - reflection loss due to insufficient matching of the antenna with the main feeder (usually P _o >0.9);

P _t - feeder efficiency, determined by heat loss (characteristics of feeders for the supplied length are given in reference books issued by the GSPI RTV);

R is the distance from the geometric center of the antenna to the observation point (slant range), m;

F _in (α) is the normalized radiation pattern;

α is the angle formed by the direction of the point;

F _g (φ) is the normalized DN in the horizontal plane;

j - azimuth, deg .;

To _f - = 1.15 ... 1.3 - attenuation factor.

At frequencies of more than 300 MHz, in the case where the near zone (induction zone) is located in close proximity to the emitter, the power flux density of the electromagnetic field is determined by the following relationship:

where: P _rad - power radiated by the antenna;

G is the directional coefficient (KND) of the antenna;

r is the distance to the antenna;

L is the attenuation of the electromagnetic flux along the propagation path.

From both dependencies it follows that the power of the effect of radio emission on the user by the mobile phone is inversely proportional to the square of the distance from the emitter, i.e. the further the decimeter wave electromagnetic wave generator of the mobile phone is located from the user's head, the less its negative impact on the user's brain. It can be argued that this effect varies in a similar relationship. Therefore, by placing the decimeter wave electromagnetic wave generator of the mobile phone at the greatest possible distance from the user's head, the harmful effect of electromagnetic radiation on the user's brain can be significantly reduced.

Utility Model Disclosure

The problem to which the claimed utility model is directed is to create a mobile communication device design that eliminates the main disadvantage of the known designs associated with a high level of exposure and possesses, along with all the advantages of existing designs of mobile phones, the minimum acceptable levels of exposure of a mobile phone user.

The technical result due to the use of the claimed utility model is to offer users an environmentally friendly mobile communication device, the design of which is characterized by a minimum level of exposure to electromagnetic radiation to the user.

The task underlying the claimed utility model, with the achievement of the aforementioned technical result in the process of its use, is solved by the fact that the design of the known radio communication device, mainly mobile, containing a housing in which the blocks and nodes are connected to the system for receiving and transmitting wireless messages, including a short-distance receiver-transmitter, a main receiver-transmitter connected to the antenna, a radio signal processing unit, connected to the main microprocessor and both receivers and transmitters, a memory unit with programs for implementing the operation of the radio communication device associated with the main microprocessor, input and display means, including an information input unit, a microphone, a speaker, a display connected to an audio microprocessor, a power supply unit including a charger connected with a battery, to which respectively all the blocks, nodes and means of the radio communication device are connected, is equipped with an additional system for receiving and transmitting wireless messages, made in the form of an individual unit located at the maximum possible distance from the user's brain, while the additional system for receiving and transmitting wireless messages includes a main receiver-transmitter, a short-distance receiver-transmitter associated with an antenna, a radio signal processing unit, a microprocessor, and a memory unit that are connected with a battery connected to the charger and forming a system for receiving and transmitting wireless messages, while the interface providing the operation mentioned s reception and transmission systems of wireless communications, provides the ability to disable the main system transmission and reception of wireless communications in the presence of the operation of an additional system of reception and transmission of wireless messages;

- as well as the fact that the device can be additionally equipped with known means allowing to implement known options, for example, a photo / video camera.

Brief Description of the Drawings

figure 2 schematically shows an algorithm - the main stages of the operation of a mobile radio communication device.

The best option for implementing the claimed utility model

The mobile radio communication device 1 (Fig. 1) can basically be made in the form of two blocks: block 2 and block 3, each of which is a system for receiving and transmitting wireless messages interconnected by a wireless interface. Block 2 can conditionally be considered the main system for receiving and transmitting wireless messages. It includes: a short-distance transmitter-receiver 5, a main transmitter-receiver 7, a radio signal processing unit 8, a memory unit 16 with programs and the necessary parameter values that allow the functioning of the main system for receiving and transmitting wireless messages, a microprocessor 14, an audio processor 19, speaker 20, microphone 21, display 22, information input unit 23, antenna 27, power battery 10, charger 12. The listed blocks and nodes are connected appropriately, forming the main system for receiving and transmitting sprovodnyh messages. The system may be equipped with a photo / video camera 17 and other known means for implementing other known options.

Block 3 is also conditionally, can be considered an additional system for receiving and transmitting wireless messages. It includes a short-distance transmitter-receiver 4, the main transmitter-receiver 6, a radio signal processing unit 28, a memory unit 15 with programs and the necessary parameter values that allow the operation of an additional system for receiving and transmitting wireless messages, a microprocessor 13, an antenna 26, a power battery 9, charger 11. The listed blocks and nodes are also connected accordingly, forming an additional system for receiving and transmitting wireless messages.

As noted above, the essence of the proposal lies in the fact that the proposed design of a mobile radio communication device provides the minimum achievable level of exposure of the user to electromagnetic radiation. Based on this, the mobile radio communication device (block 2), representing a conventional mobile phone having corresponding nodes and blocks for receiving and transmitting wireless messages, as well as other known options, is equipped with an additional block 3, which, unlike block 2, contains nodes and blocks necessary only to provide the function of receiving and transmitting wireless messages, and all the actions necessary to work with the radio communication device are carried out using block 2. Thus, offering this mode of operation of the device is implemented when only the main receiver-transmitter 6 of block 3 is operating in the transmit-receive mode of wireless messages, and information is exchanged between blocks 2 and 3 through an interface formed by short-distance receiver-transmitters 4 and 5, respectively, of blocks 3 and 2, for which, for example, a Bluetooth system can be used, the radiation power of which is an order of magnitude lower than the radiation power of GSM, and the signal is further processed by appropriate means and locks of the main wireless communication system - block 2. Such a design, when the main source of powerful electromagnetic radiation, for example, the GSM transceiver is located at a considerable distance from the user's brain, has made it possible to reduce the power of electromagnetic radiation affecting the user by a mobile radio communication device.

A mobile radio communication device 1 is not limited only to the function of a mobile phone, it can be a personal communication system, a personal digital assistant, or another communication device that provides the ability to transmit and receive signals both to the network and from the radio communication network. The main transmitters-receivers 6 and 7 of blocks 3 and 2, respectively, can be fully functional cellular radio receivers-transmitters that operate in accordance with any known standard, for example. Global System for Mobile Communications (GSM), cdmaOne, cdma block 200, UMTS, Broadband CDMA, WiFi, WiMax and others. The microprocessor 13, can be used as the controller of the operation control unit of block 3, which performs actions in accordance with the programs and / or data stored in the memory unit 15. However, the control functions can be carried out both in one microprocessor 13 or 14, and in multiple microprocessors. The processing units of the radio signal 8 and 28 process the signals received and transmitted, respectively, by the main receiver-transmitters 7 and 6. The frequency band received by the receivers-transmitters 7 and 6 of the signal in the processing units of the radio signal 8 and 28 is encoded, divided into separate channels, demodulation and decryption in accordance with current standards and protocols, and is sent to the receiver-transmitter 7 and 6 for transmission to the radio network. The frequency converter of the radio signal processing units 8 and 28 performs its encoding / decryption functions using any known method that is suitable for the network in which the mobile radio communication device 1 operates. The radio signal processing units 8 and 28 also provide conversion of an analog signal, such as a user's voice, transformed in the microphone 21, into an analog signal, into a digital signal, which is then encoded using any appropriate protocol for this network. Block 2, as a rule, contains an information input block 23, using known means, such as a keyboard, touchpad, joystick control dials, control buttons, either individually or in any combination thereof. This allows the user to dial subscriber numbers, execute commands necessary when using them, view the menu and the contents of its individual items, make selections, etc. Using a photo / video camera 17, a speaker 20, a microphone 21, an audio microprocessor 19, a user can take photos / videos by capturing not only the image, but also the background sound accompanying it, which is converted into a digital signal by means of an audio microprocessor 19. Chargers 11 and 12 recharge the batteries 9 and 10 when the chargers are connected to an external power source. Batteries 9 and 10 provide power to units 3 and 2, respectively, when operating in stand-alone mode.

Figure 2 shows the algorithm of the proposed mobile radio communication device, which schematically shows the main stages of the functioning of the proposed device in two modes of operation. Since block 2 is a regular, widespread mobile phone, the work of which is well known to everyone, in Fig. 2 only those fundamental differences are characteristic that are characteristic of the claimed device. A similar approach was used to describe his work.

The radio communication device 1 operates as follows. After turning on the device 1, a signal is searched for the short-distance receiver-transmitter 4 of block 3. If a signal is detected, which means that the device contains block 3, a connection is established between the short-distance receiver-transmitter 5 and 4 of blocks 2 and 3, respectively, i.e. A wireless interface is formed that effectively connects said blocks. By means of the formed interface, the radio signal processing unit 28 is connected to the main receiver-transmitter 6 of block 3 and the main receiver-transmitter 7 of block 2 is turned off. This is the main mode of operation of the radio communication device 1, while the main receiver-transmitter 6 of block 3 operates at the maximum possible distance from the user's head, significantly reducing the level of its exposure to electromagnetic radiation, and the operation of the radio communication device 1 is carried out using the appropriate means of unit 2.

In the event that the signal of the short-distance receiver-transmitter 4 of block 3 is not detected, a command is generated to turn on the main receiver-transmitter 7 of block 2, after which it is connected to the radio signal processing block 8 of block 2, and the main transmitter-receiver 6 of block 3 disconnected from the radio signal processing unit 28 of block 3, then the radio communication device 1 operates in a conventional mobile telephone mode.

A mobile radio communication device, made in accordance with the proposed design, provides a significant reduction in the level of exposure of the user to electromagnetic radiation, thus virtually eliminating the possibility of a negative effect on the user's brain. It can be argued that users are offered an environmentally friendly means of mobile radio communications - a mobile "green" phone.

The proposed mobile radio communication device can be easily manufactured on existing equipment and technological equipment, because it uses widely known and manufactured by industry components and assemblies.
