DESCRIPTION

of the patent for an industrial invention entitled: ?System for managing telephone calls in the car?

The present invention ? relating to a system for managing telephone calls and data connections in cars or other similar means of transport.

In particular, the present invention ? relating to a system for managing telephone calls and data connections in cars or other similar means of transport, suitable for reducing exposure to electromagnetic waves from the use of cell phones inside the vehicle.

The electromagnetic pollution? a topic known and debated for years, however there is no? state of the art uniform and complete attention to the damage caused. This frequently results in an underestimation of the problem.

With reference to the possible biological effects due to exposure to high frequency electromagnetic fields, the important physical parameters to be taken into consideration are the frequency (it is measured in Hertz and is usually expressed in MHz); the power level (it is measured in Watts and is usually expressed in dBm); the duration of the exposure, the distance from the source.

Each frequency corresponds to a wavelength and to each of these, a different interaction with the various biological tissues that make up the human body. Pi? ? high the power of the electromagnetic field, greater ? stress on the human body. In general, major ? the distance that the? electromagnetic wave must? travel?, greater? the power to be supplied. In simple terms ? as if to make ourselves heard at a greater distance we raise our voice. As in the case of acoustic signals, the ear? solicited both by many low-intensity sources? both from a few to high intensity? sound, in the same way the body ? solicited in confined spaces both by many low intensity sources? (Bluetooth) both from a few high-intensity sources? (the mobile phone during the call). Pi? Yes ? far from the minor source? exposure to radiated electromagnetic fields. The time of exposure to electromagnetic fields? a multiplier of polluting effects. Therefore, ? It is essential to accurately evaluate the level of exposure in places where one remains consecutively for many hours (car, office, bedrooms, etc.).

According to some studies, some effects of exposure to electrosmog are more? significant in certain groups d? age? (children and adolescents).

So keeping the right distance from the source of the electromagnetic field and avoiding long exposures can effectively reduce the effects of this type of electrosmog source.

The mobile phone allows wireless communication with the base station in the cell (cellular system). During the call ? the main source of electrosmog in a confined space. Many people stay in a means of transport for a long time and use the mobile phone to make long and/or frequent calls. The regulation of the use of the mobile phone in the car is not? still focused on the aspect of the harmful effects linked to exposure to electrosmog.

For road safety, vehicle manufacturers have now made a standard connectivity system available. between car and smartphone. Normally the system used ? the Bluetooth. This option, while ? very effective from the point of view of road safety, it does not improve, on the contrary it partially worsens the level of exposure to the electromagnetic fields connected to the phone call. In general the? auto ? a confined system whose walls are predominantly metallic. From the point of view of the propagation of the electromagnetic waves that are generated during a phone call, the car is not? the best context (the free space). The attenuations introduced by the interaction with the car force the telephone to increase the output power level of its radiant system. Part of the energy that does not reach the base station, compensated by the increase in power, is partly accumulated in the car that acts like a sounding board. To the electromagnetic fields generated by the call are added those of Bluetooth. Consequently, during a call in the car, people are exposed to significant levels of electromagnetic fields potentially capable of inducing harmful effects.

Various systems for managing telephone calls in cars are currently known.

A first example of a known technical solution? cited in patent text US2020037267A1 , which discloses a system and method for mitigating man-made electromagnetic radiation, comprising a wireless transmitting antenna for radio wave emission which communicates with a personal device equipped with antennas. Said antennas include a wireless receiving antenna for receiving radio waves which is used in a safe space designed to substantially minimize harmful electromagnetic radiation. The safe space can be created through the use of different options, a material to absorb harmful electromagnetic radiation, or systems to reduce the transmit power of the antennas and/or select a preferred wireless access point that minimizes the distance between the device's antennas personal device and a wireless access point, preferably simultaneously reducing the power or intelligently disabling the transmission power or wireless communications of the personal device, intelligently disabling an unselected wireless access point; and/or shift a wireless transmission frequency to use less harmful frequencies.

Again, the prior art technical text US6225954B1 describes a broadband antenna device integrated in a vehicle for receiving and transmitting RF signals, without transmitting electromagnetic radiation into the vehicle passenger compartment. There? is achieved by providing a housing transparent to RF radiation in at least one direction. The housing being disposed within the vehicle compartment. The housing including means for suppressing RF radiation in substantially all directions facing substantially the interior of the motor vehicle cabin as viewed from a radiating element disposed in the housing.

Finally, the patent application US6614402B1 relates to a mobile transmission antenna for vehicles comprising a monopole to which ? associated with a reflector. The group what? format is mounted on or adjacent to the interior surface of vehicle electromagnetic wave permissive members, primarily vehicle windows, such that said reflector faces the interior of the vehicle as viewed from the monopole. During a transmission, this configuration simply and economically reduces the incident radiation of high-frequency energy entering the vehicle to a harmless level. The antenna? further protected from any unauthorized manipulation from the outside and does not look like an antenna.

However, these known systems do not automatically and effectively reduce the electromagnetic waves to which people inside a vehicle are exposed during a telephone call with a mobile phone.

Purpose of the present invention? provide a system for managing telephone calls in the car which allows to avoid exposure to electromagnetic fields generated by the mobile phone during a call in the car, thus having characteristics such as to overcome the limits which still affect current systems, with reference to the technique Note.

According to the present invention, a system for managing telephone calls in the car is provided, as defined in claim 1.

For a better understanding of the present invention, a preferred embodiment is now described, purely by way of non-limiting example, with reference to the attached drawing, in which:

- figure 1 shows a schematic view of a system for telephone calls in cars, according to the prior art;

- figure 2 shows a schematic view of the system for managing telephone calls in cars, according to the invention;

- figure 3 shows a schematic view of the system for managing telephone calls in cars, according to the invention.

With reference to these figures, and in particular to figure 2, a system for managing telephone calls in the car? shown, according to the invention.

In particular, the system 100 for managing telephone calls in the car according to the invention comprises:

- a mobile phone 101, consisting of an antenna, a 2G/3G/4G or 5G module, a SIM, an audio block, a Bluetooth module.

- an antenna 102 used for telephone communication placed outside the passenger compartment of the car 50.

Advantageously, the problem of exposure to electromagnetic waves in the passenger compartment? totally solved. In fact, the cell phone is in a much better condition. close to the free space and therefore does not have to compensate for the attenuations by increasing the power. Furthermore, thanks to the invention, the metal structure of the car partially shields the electromagnetic fields emitted by the antenna placed on the outside of the car. As a result, people in cars are not exposed to harmful electromagnetic fields.

Simplifying, a mobile phone? composed of an antenna, a 2G/3G/4G or 5G module, a SIM, an audio block, a Bluetooth module.

According to currently known systems, during a call in the car, the cell phone uses the car's audio block via the Bluetooth module (serial), while it continues to use all its other components. In some cases, via cable, recently yes? added display sharing and voice commands.

According to the invention, the car 50 or the vehicle has, in addition to the Bluetooth module, its own cellular module and antenna. According to the invention, via Bluetooth (serial) the mobile phone and the car only share the SIM data.

Therefore according to the invention, during the call the cellular module, the Bluetooth module, the audio and the antenna of the car are activated, while the Bluetooth module and the SIM are active on the telephone. As previously mentioned, the antenna? outside solving cos? the problem of electrosmog.

In a variant of the invention, the SIM manufacturer could supply a twin ?courtesy? to your customer to insert permanently into the machine.

To implement the? Invention? necessary to implement the following system:

? The car manufacturer designs the car by integrating cell phone locks into the car

or alternatively a third party develops approved systems applicable to the car

? Does the smartphone software and car manage the ?mode? car?

Today some cars mount already? a cellular communication system in order to offer internet connection. However, there is no possibility to use the machine to make calls with your shared SIM in the mode? described, between mobile phone and car.
