Description

PASSENGER TRANSPORT PROTECTION SYSTEM

TECHNICAL FIELD The invention relates to personal protective equipment, such as screens, splash masks, masks and other measures to prevent a person from coming into contact with harmful substances such as micro-organisms. More particularly, the invention relates to a device and additional measures that help to limit the spread of harmful substances by persons through contact or inhalation. The protective equipment can be used in means of transport such as trains, buses, metros, trams, passenger vans, water buses, aircraft and other means of personal or public passenger transport, but also in private and public areas such as assembly companies, the meat processing industry, distribution centers, shops, educational institutions, offices, museums, cinemas, theaters and many other places. Even more specifically, the invention relates to measures to limit the spread and inhalation of viruses, such as SARS-cov-2 (so-called "coronavirus"), and to prevent COVID-19 in persons.

BACKGROUND There are many protective devices on the market and in general they can be used for specific applications, such as working with hazardous substances, for use in welding activities, etc. or for use in the medical world. They are also often very expensive devices. They are large, heavy and noisy and therefore very taxing on the wearer. Maintenance is also often expensive and complicated and requires the use of tools and can only be performed by the professionals in this field. The world is now facing the new coronavirus which causes a disease COVID-19. The virus often expresses itself in the beginning like a cold does. It can cause deadly pneumonia. Many measures are and have been taken to prevent the spread of this disease. As a result, the need for good protective equipment is greater than ever.

To come up with good protective equipment, we first need to understand the current and future dangers associated with a pandemic such as the one caused by a virus such as the coronavirus.

Research and comparison with other known viral diseases provides a picture of the properties of the virus.

Much is still unknown, however, what is known is the property that the virus is transmissible from person to person.

Transmission can be through saliva particles through direct or indirect contact or through airborne dispersion.

Coughing is considered a major cause of airborne spread, however, spreading through normal breathing may also be a cause.

A characteristic such as fever is also seen as a disease associated with this virus.

Unfortunately, more and more recent reports show that spread can also occur without this disease.

However, we can now also determine a number of issues with regard to the distribution.

Due to the enormous increase in air traffic, the spread has been faster than ever before.

There are reports of illness from the current virus from almost every country in the world.

Whether the reports are correct in terms of numbers of infections and numbers of deaths is also questionable.

There would be countries that for political reasons state the numbers lower than they actually are.

Which is also clear that spreading on cruise and other ships can happen quickly.

Statements that are given include that diffusion occurs through the existing ventilation systems.

Recent discussions are also underway that these systems may also be the cause of the massive spread in care homes.

Another problem is that there is almost no country that, from the start of the outbreak that started about four months ago, had sufficient resources and possibilities to be able to determine the numbers of infected persons for one hundred percent reliably.

In the meantime, tests have been developed for such cases at an unprecedented speed that can demonstrate the disease.

It has also been established that people affected by the virus, as with many other viral diseases, have produced antibodies, which can be demonstrated by blood tests.

By carrying out this blood test on a larger scale among blood donors, we are getting a better picture of the spread of the virus.

In the Netherlands and Belgium, at the time of writing, the number of persons determined by this method is approximately 4% of the population.

There are also problems about the numbers of fatalities. Countries use different methods. The number of fatalities mentioned in the Netherlands is seen as far too low. Comparisons with deaths in previous years support these thoughts.

A lot of research is being done to develop a vaccine to prevent or cure this disease. When and whether this will work is still an open question.

The development time of a vaccine normally lasts 10 to 15 years. The hope is that it will now happen in about 18 months, but that could turn out to be very disappointing. Unfortunately, a study with existing medicines that were seen as very promising does not seem to work.

A very positive development is that, by using and administering antibodies produced in the blood by healed persons, severely affected patients may be able to heal.

The fight against the virus causes a lot of economic damage worldwide. Most countries have adopted the tactic of trying to limit transmission of the virus by applying no-contact orders.

The measures taken are aimed at preventing transmission and have a huge impact on society. Some measures are: - Stay at home as much as possible - Keep 1,5 meters away from others - Wash your hands regularly with soap and water - Cough and sneeze in the inside of your elbow - If you have symptoms such as cough and or fever, enter home insulation. - Use paper tissues Measures have been imposed to prevent contacts through work, through school, through travel and through all kinds of social gatherings. Measures have been taken to ensure that contacts in healthcare professions are as safe as possible, by using protective aids such as mouth caps / filters, face masks, gloves and protective clothing.

Unfortunately, there is a huge shortage of suitable resources worldwide. Initiatives are being developed everywhere to eliminate these shortages. An important part is the face mask. Many masks in various forms have been created or are being developed.

Also for medical care of the sick an enormous attack has been and is made on both care providers and available resources. That is why attempts are made to arrive at “Flatten the Curve” using methods, based on the assumption that multiple waves of infections may arise until everyone has produced antibodies or an effective vaccine is developed and available.

A number of other measures that are taken in society are placing shields, for example at supermarket checkouts, cleaning handles and setting up a one and a half meter economy. Studies are underway to map virus survival rates and times on various materials. Unfortunately, the virus appears to be able to survive for a longer period of time on many materials, such as stainless steel, cardboard and plastics.

Gatherings of larger numbers of people are prohibited and the number of people in a vehicle is strongly limited, travel is often prohibited.

All these measures paralyze society and, in addition to a lot of suffering, have enormous consequences on the economy. Worldwide amounts about the economic damage of thousands of billions of euros or dollars are mentioned, which is disastrous given the impact on society. Well-known airlines and hundreds of thousands of other companies are threatened with bankruptcy. Unprecedented government support seeks to prevent these bankruptcies and preserve the associated employment opportunities. However, how long can this be sustained, the government deficits will rise to the intolerable. That is why measures are being taken to gradually get the economy running again, based on the one and a half meter economy in the Netherlands.

Although the numbers on proliferation give some hope that proliferation is starting to become manageable, it is reported to be very successful in this mentioned Germany so far. Merkel's top adviser, a well-known virologist, warns of a second powerful wave of corona infections, which he says could get out of hand. The infection rate (reproduction value) in Germany has increased again in recent days, according to media at the time of writing.

A major problem in the distribution is the transport of groups of people in public transport and other forms of passenger transport. The amount of travelers who can use these transport modes as a result of these measures is dramatic. The majority of the seats should preferably remain unoccupied. Placing shields hardly solves this and is considered unworkable by experts. Problems and risk of transmission arise when boarding, at walkways, etc.

An additional problem is that viruses can survive on shields and other materials for extended periods of time. As a result, spread can still happen very quickly.

The public transport companies are now supported by the governments and are calling for only travelers who practice vital professions to use this. However, how long will this crisis last, the costs for the economy are only slightly bearable. That is why we are looking for means that make traveling and certainly traveling by public transport possible again in larger numbers.

One development that, more or less coincidentally, could contribute to this is the Turbo plan. A Dutch patent application that formed the basis for this plan has been submitted by the applicant under patent application number NL 1043058. This plan is and was intended to improve the capacity and affordability of public transport in an environmentally friendly and economical way. Part of the turbo plan is the almost automated transport of goods, in combination with the transport of people. Due to the modular and regular set-up, people come together much less in larger groups. This makes it much easier to take measures against the spread of viruses. See the website www.turboplan.nl for the item Corona. It is also important that if full implantation of the turbo plan had already taken place, then the supply of supermarkets and the transport of lighter goods, which has now led to considerable problems for some time, could have continued in the same way almost without any problem. to go.

As a result, the revenue models for the public transport companies would have remained much more intact than with the current system, which can only continue on a very limited scale with enormous financial support. However, its implementation and implementation will take time. Together with an important international knowledge institute, the railway infrastructure manager responsible in the Netherlands will start studies that could lead to the implementation of the plan. The benefits that the turbo plan can offer in terms of security and manageability with regard to virus outbreaks may accelerate implementation.

The current coronavirus is still seen by some experts as a mild form, despite the horrific impact it is already having with the enormous personal suffering and disastrous impact on the economy and society. In other words, “it could be much worse”.

If we look at the current state of affairs, countless panic measures are being taken. A disadvantage is that these often only give very limited results. Many measures are short-term matters.

Effective measures are needed that will provide every traveler with sufficient protection.

Air traffic is largely at a standstill and causes a lot of economic damage. The risk of contamination and spread by persons is high, given the worldwide network of air traffic and the limited space per person.

Effective protection can consist of a good face mask in combination with measures that, through contact such as touching control buttons or handles, can prevent contamination and transfer. Gloves can be used, whether or not in combination with cleaning agents, air in vehicles can be continuously cleaned via air treatment with, for example, Ultraviolet (UV) light, and protocols to be followed can be prescribed.

When not in use, the means of transport can be cleaned with intensive UV treatments or other cleaning methods. This can also be done before or after every ride or journey. The necessary protective measures to be taken to protect persons but also to prevent the protection of materials and electronic and other systems speak for themselves. This is especially true if cleaning is done using ions and/or other intensive cleaning methods.

Face masks can make an important contribution in this regard. Unfortunately, the mouth caps do not offer sufficient proven safety. A recent additional problem is that spread by persons without the symptoms seems to be occurring in an increasing number of cases. There are also more and more reports about animals (minks, cats, tigers) that have been infected by the virus, possibly transmitted by humans. There are also more and more experts who point to the fact that children often do not become noticeably ill and can still be spreaders of the virus. Furthermore, fellow travelers are worried by people who sneeze as a result of, for example, hay fever. The invention therefore proposes a number of improvements. The invention preferably takes into account the application of and optimum use of materials with regard to maintenance, cleaning, distribution and ease of use. See the item corona on the site www.turbolan.nl. Measures, resources and options that can be rapidly introduced en masse should also be considered, either by adapting existing resources or by introducing resources that can also make a good contribution in the longer term.

THE INVENTION The invention is aimed at low cost, comfort in use and maintenance and poses no problem in transport or storage. The invention is also adapted to the fact that cleaning the protective means and possibly replacing the filters is a simple and safe operation, in which there is no longer any risk of contamination or spreading. For this reason, the design and properties of the low-cost filters and other parts to be replaced were taken into account in the design. This makes the use of the invention ideal for the traveler. Many travelers are afraid to use public transport and/or plane with only a mouth cap as protection. Theater, cinema and, for example, visiting museums can also be performed again without this fear. The problem of the glasses catching when wearing mouth caps has also been solved for spectacle wearers. Difficult breathing is also a problem for many people when using a mouth cap. That too is no longer a problem due to the invention. The invention consists of a number of parts which individually or together achieve the intended result. An important part of the protection system is the face mask.

Face masks have mainly been developed to quickly give larger groups in specific professions an extra form of protection during the exercise of their profession. They usually consist of a transparent plate provided with means for fixing it on the head. The downside is that once used they must either be thrown away or cleaned properly.

If these face masks are used as protection during passenger transport, these masks do not provide adequate protection against the spread as a result of air currents in the means of transport. That is why we come up with affordable and user-friendly solutions that not only stop viruses, but also destroy as much as possible.

In one of the preferred embodiments, a part of the protection system consists of a face mask with a transparent screen that can preferably be applied to the head with aids. Preferably, parts can be folded together as with a spectacle frame, whereby contacts or extra clips can be worked with, after which it can optionally be rolled up or folded and stored in a suitable tool. Cleaning and other protective equipment can possibly be stored in this aid.

The base screen is preferably provided with sides that prevent exposure to droplets due to coughing of the wearer himself and/or fellow passengers. The basic screen can be provided wholly or partly on one or both sides with one or more conductive metal layers or other conductive materials/coatings arranged as a grid, whether or not insulated, or can be provided with grids incorporated in the material. This material is, for example, copper, which naturally has special properties for combating micro-organisms such as bacteria and viruses for a long time. Both are designed to be put under electrical voltage. This voltage is preferably, in addition to being safe, suitably high so that an electrostatic filter is formed, which is suitable for effectively eliminating viruses. This applies to viruses originating from the user of the mask as well as viruses originating from fellow passengers. Protections against short circuit or deterioration of the conductors can be included.

9 à Since nowadays many people have access to telephones and/or power banks and, moreover, many of the current public transport vehicles are equipped with USB connections, it is preferable to obtain the required electrical energy from them. The different layers of protective agents can be applied in various ways. They can consist of mass-produced custom sheets - with the specified properties, which can be easily exchanged by the user. A number of parts can hold the sheets due to the electrostatic properties. Clips and/or spring connections, clamp or insert edges, frames, LM or other attachment methods can also be used. After use, the sheet can be cleaned or thrown away. A point of attention is that no further spread may occur. The invention also proposes solutions here. The above results in a consumer product in which care is taken for safety and good options for cleaning the mask or parts thereof, whether or not with the help of specific aids and can be done in, for example, in a standard dishwasher or under a tap. This can destroy the now troublesome virus. Since it may take a long time before we are out of this crisis, personalization of these face masks can be considered. To this end, the invention proposes to provide a coupling, attachment or connection to a | glasses, sunglasses, sweatband, a cap/headgear, headphones, head or neck support as used in bus and Air travel, may be made and possibly customized for these products and/or for the user. Other products can also be adapted or made to measure and connected to the screen and/or other consumables. This customization can be done, for example, by scanning or photographing someone's head in 3D, with or without glasses or other accessory, after which the aid and specific pieces/parts can be made using 3D printing with a special program. This can be done nationally, for example via optician chains.

DETAILED DESCRIPTION OF THE FIGURES

The invention is described below with reference to figures and references and additional embodiments.

Figure 1 shows an embodiment of the protective device 100 in which a preferably transparent plate 1014 is attached to a brace 110. The brace can be secured around the head with mounting strap 111 of the brace. An electrostatic section 102 which is optionally replaceable is provided on plate 101a. At the location of section 102 there are one or more openings for the passage of air. Section 102 thereby forms an electrostatic filter. Section 102 is powered through unit 103 which houses a voltage and power regulator and a battery, battery, or connector for connection to an external power supply. Unit 103 is connected to section 102 by power cables 104 and 105 which may form a positive and negative pole (optionally alternately). Section 102 preferably consists of very thin lines of an electrically conductive material, so that person 200 can still see through the plate 1014 well. Section 102 may also be partially lined so as not to obscure the view.

The protective device can be built up or expanded with a number of parts. The operation of the individual parts is optionally enhanced by combining other suggested parts with each other. In a preferred embodiment, the electrostatic section is a grid of closely spaced wires connected alternately to one of the poles, leaving space between the wires for air to flow through. In this way, an air stream can pass through the electrostatic filter, which is disinfected when passing through the electrostatic filter, for example by the breathing of person 200.

Figure 2 shows a person 200 wearing the screen

100. Screen 100 is secured to the head of person 200 with bracket 110.

Figure 3 shows an embodiment of the protection device 100, with two separated and placed one behind the other (at least partially transparent) plates 101a,b. Multiple plates are also possible. The plates 101a,b can consist of several parts, the effective part being a spare part that can be cleaned or replaced by a new insert. An air layer is present between plates 101a,b. A protective agent to repel harmful substances can, for example, be applied as a coating to both sides of plates 101a,b. Alternatively, for instance a bacteria or virus killing coating or substance can be applied on the inside and/or outside or on all sides of the plates 101a,b.

In the figure, an embodiment is shown with filters 106a,b which can filter ambient air before the air is inhaled by person 200.

The filters can be placed between plates 101a,b and air drawn in from the side by person 200 passes through filters 106a,b and then through ventilation holes 107 to person 200 in the direction of arrow 1000. Ventilation holes 107 are in this case only in the plate 1014 facing the face. This has the advantage that a screen becomes possible through which it is possible to see well, without much obstruction and yet effective in filtering at least a significant part of the inhaled air. When exhaling, the air follows the path in the opposite direction and is filtered again in this way before being added to the surrounding air. This prevents a person from having a lower chance of ingesting harmful substances and it also prevents a person from infecting 200 others with, for example, a virus, such as the corona virus.

Blocks of filters 106a,b are shown in the figure. For a better operation, the plates 101a,b are closed all around so that no false air is drawn in. At the height of filters 106a,b, openings can be provided through which air can pass via arrow 1000, for example. As an alternative, a filter can also be positioned wholly or partly around the edges of the plates 101a,b, wherein the filter itself (partly) forms the partition between plates 101,b.

Instead of the configuration with 2 or more plates, any configuration can be made with filters that filter inhaled or exhaled air.

In addition to physical and/or chemical filters such as dust filters, active carbon filter, or electrostatic filter, or any combination thereof, UV lighting can also be applied, preferably near the mask and preferably arranged in such a way that exhaled or inhaled air is illuminated with these so-called UV cleaner.

Viruses and microbes can be killed by using UV light sources (eg diodes). This is preferably done with due observance of safe use by persons. For example, by using a series of lower power diodes, so that the optimal effect can still be achieved due to the possible distributed arrangement of the different diodes compared to a lower, but possibly more harmful or dangerous intensity when using only one diode or other UV source.

For example, the arrays of diodes can be arranged along the edge of the screen, directing the light toward the plate or plates.

An alternative to the use of UV diodes is a laser diode. These can be arranged in the same way as the previously described ring and reflective light can also be used.

The invention proposes four configurations: A first configuration concerns an arrangement as mentioned in clause 61-62, but then with laser diodes, or in combination with one or more laser diodes.

In a second configuration, the UV diodes in a configuration similar to the first configuration are replaced by low cost standard laser diodes with just sufficient power and optimum wavelength and of which enough are placed in the ring to form a laser screen. The beam / beam width can be optimally chosen for this and these beams can also be reflected.

In a third configuration, UV laser diodes are used in one or more of the above-mentioned arrangements, the laser diodes being chosen at optimum beam width, etc. so that this forms a concentrated UV screen.

In a fourth configuration, any combination of the above configurations can be chosen.

Thus, a UV light source can also be embodied as a UV laser module which emits ultraviolet laser light having a wavelength of preferably 200 nm to 280 nm. To evenly disinfect an area with efficiency, preferably by irradiating as many viruses and other micro-organisms as possible, the laser module or an arrangement with several laser modules can be such that the laser module emits the laser light to one or more reflectors that a laser controller having an electronic circuit and a power source (e.g., that power source as suggested hereinabove) is controlled to move and disperse the laser light in different directions. A rotating one. For example, a mirror can cause the inside of an air hose to be discussed with laser light. In this way, a kind of wall of UV laser light can be created that destroys or damages the virus that is moved along that wall to make it harmless. Multiple reflectors can also be used to reach more places.

The laser light can also be aimed at a refracting object such as a prism, so that the light can be spread in the desired direction or over a larger area.

A specific effective wavelength is 266 nm. In this way, the UV laser light can perfectly cover a typical tube diameter of an air blow of 2 to 4 centimeters. Application can also take place behind the screen or in the MOA. Preferably, a laser diode is used with a peak power that is within the legal limits for consumer use, such as a maximum light intensity of 25-35 mJ/em 2 . In the publication “Development of ultraviolet laser for disinfection of potable water” by Bhar et al., 2006 it is stated that disinfection of a virus such as Hepatitis A in water takes place at a UV intensity of 20mJ/cm2. Since in that case a class 3B laser is required, extra attention will have to be paid to safely confine the laser and to prevent the escape of laser light to the environment. However, when used in an air environment of e.g. the air blows, and certainly when LEDs or laser diodes are arranged in a ring and have overlapping radiation areas, less power will suffice. may fall (similar to lasers in CD players). By increasing the duration of UV exposure when using the lowest possible power, possibly in combination with the other measures mentioned herein, a disinfecting effect of the laser (and also the UV laser) is to be expected. By measuring the ozone concentration in the area irradiated by the laser, the power or the radiation duration can be adjusted downwards as soon as the ozone values become too high.

The laser controller can be arranged to change parameters of the laser, for instance depending on the required disinfection or adapted to a specific type of contamination or micro-organism. Parameters are, for example, frequency, bandwidth, intensity, pattern, density, beam width, angle, amplitude, wavelength, color/frequency spectrum.

Figure 4 shows a person wearing a protective device, the screen 100 being connected to an exhaust system of a vehicle such as a public transport bus or in an airplane. The figure shows person 200 next to a window 300 of a bus. In ceiling 301 is an exhaust system with a connector 302 to which a flexible tube 303 can be attached at the upper end. At the lower end, tube 303 can be attached to shield 100 via connector 304.

If person 200 receives or buys a screen as a passenger on the bus, then person 200 can sit in a free place in the bus, preferably at a minimum distance of 1.5 meters from fellow passengers. Person 200 can then couple tube 303 to screen 100. The extraction installation is then put into operation and causes a negative pressure in the mask, so that all exhaled air is discharged as much as possible via the extraction installation, in order to prevent possible contamination of fellow passengers. Since the protective mask is a highly personalized feature, it is expected that embodiments will be owned and made to the liking of the person. Regulations regarding these products can be made.

If no extraction is available, then depending on the situation or the screen 100 (especially if used as personal protection) it is possible to opt for;

1. Inhale through the slats and exhale with the slats closed, extending the operating time. The exhaled air can then flow away through openings due to the excess pressure it causes, via openings provided for that purpose.

2. applying additional own ventilation to discharge the exhaled air when used according to 1.

Furthermore, when using an (active) carbon filter, the operation is optimal at a relative humidity of less than 80%.

For these reasons, if an extraction system is connected to the mask, such as in the case of possible long-term air travel, a provision can be made in or on the protective device that ensures that the airflow only passes through the applied cleaning devices for cleaning against viruses/microbes when inhaled. and that when exhaling (much more humid air) the air goes directly to the exhaust.

This can consist of a kind of ventilation grille in which the movable slats (possibly equipped with antibacterial items) can consist of foils that open due to the air pressure and thus allow air to pass when inhaling and block air due to the opposing air flow when exhaling. The above ensures a longer and possibly more efficient operation of the screen.

To prevent false air from being sucked in or blown out past the screen, the screen can be designed such that it can be fitted form-fittingly on the face of the user, for example around the mouth and/or nose.

By implementing the screen in this way, the function of a mouth cap is also (partly) taken over. Part of the screen can optionally be designed as a (removable) mouth cap and thus integrated into the screen.

Other measures The face mask is an important part of the personal protection and protection of other persons. Additional system components can be used to prevent the spread of the virus during the transport of several people at the same time. Particularly in and around transport modalities, the following components can be applied to optimize the safety aspects of the passenger transport system. Physical barrier A barrier between the different seats of the passengers. This can consist of a preferably transparent non-combustible material that is applied as a cover between and behind the seats in a way that offers protection against the spread of the virus. The front could be attached to a fixture on the back of the next row if desired.

The top can come together in such a way that it does not hinder the traveler and also offers the possibility of being connected to an air extraction installation of the means of transport. This could be done with, for example, a plate/coupling piece as the top, on which the connection for the suction for the face mask is then also located. The chosen material preferably has anti-virus properties and is suitable for cleaning with UV and/or other cleaning methods.

Depending on the circumstances, only a part of the total number of chairs could possibly be provided with screening, whereby the extraction facilities and possibly partial screenings would then be fitted.

As an example, let's take an airplane with rows of three-seat seats side by side on each side of the aisle.

We could only provide the middle seat with an almost complete shielding.

The window and aisle seats will be partially screened.

Along the aisle there will be a screening curtain on both sides with options to go to and from the seat.

Disinfectant extraction installation The means of transport is provided with an air extraction installation (hereinafter referred to as "exhaustion installation"), which includes facilities that kill bacteria and viruses.

It is important here that the virus cannot be transferred from one passenger to another via this system.

We cannot make the air extraction too strong because that could lead to other disadvantages that can cause health damage or other unpleasant things.

A possible measure could be to include a virus killer or other facility in every extraction mouth.

Hands-free cleaning device Another measure can consist of installing a hands-free cleaning device for hands at the entrances and exits of means of transport, combined with a protocol that contains a number of actions and rules to be followed, such as the mandatory cleaning of hands, use of protective equipment, walking direction, the prohibition to make unnecessary movements in the vehicle, etc.

Smart allocation of seats Immediately upon boarding a passenger, a passenger is assigned a (mandatory) seat with a prescribed walking direction.

This could be combined with a travel reservation system.

Another measure may be that along walkways, flexible or non-flexible, preferably transparent screens (with location numbers) and notches are hung.

You can then go to the assigned seat via the notches.

UV cleaning Another measure can consist of installing suitable UV lamps that can be switched on when the vehicle is not in use. This could be at the end of any ride or journey. Switch-on preferably takes place with the necessary safety regulations and good measures and safety provisions and could take place remotely or from the outside of the vehicle. The safety provisions are preferably such that no activation takes place as long as there are people in the vehicle, not even as a result of an accident.

Other disinfection measures These measures concern the limitation and cleaning of protective and other means. Virus spread can happen through careless use of protective equipment. Examples are incorrectly taking off protective gloves or incorrectly removing used mouth caps. It can then still lead to infection or spread of viruses. Therefore the following measures: The protective measures for persons are only removed after leaving the mode of transport such as airplane or train or bus, etc.

By now installing facilities at airports, stations, bus stops and possibly shopping centers in which protective equipment and possibly other items such as clothing and/or luggage are effectively cleaned with, for example, powerful UV sources (or other suitable agents), we prevent spread. If potentially contaminated protective equipment is taken home or to work, there is a chance that contamination can also occur there.

At an airport one usually has a unit with a conveyor belt to check luggage and clothing. By including a facility here (possibly on the tape for the recording equipment) with such a UV source, the items can be cleaned of viruses in a responsible manner and further spread is prevented. This can be done before and after the trip. The thousands of control devices present worldwide can in this way make an important contribution against the spread of viruses.

Furthermore, cleaning cabinets with such a powerful UV source can be installed at airports, stations, platforms, shopping centers, etc., with great attention to safety. A possible provision against improper use could be that the provision can only be used through the mandatory use of a bank card, possibly with a debit amount of 0.0. This makes the cabinet accessible and, if desired, you can see who has used it. Special storage means can be made whereby potentially contaminated consumables can be placed in a compartment or tray, bag or other aid, filled with disinfectants. Various replacement / utensils and protective equipment and disinfectants can also be placed here. In the near future we will continue to be confronted with new viruses that will have a recurring impact on society. The present invention will contribute to make society resistant to this.

In one embodiment, an external mobile decontamination device (hereinafter referred to as MOA) can be coupled to an air hose with the screen. In this case, the screen itself does not necessarily have to be provided with the aforementioned protective equipment, which must, among other things, be provided for disinfection. Alternatively (or additionally), these protective devices may be incorporated into the external device. Filters such as dust filter, electrostatic filter, UV lamp, HEPA filter, activated carbon filter, membrane filter, ionizer, can be provided in the MOA to filter the inhaled or exhaled air or even just ambient air. If a UV lamp is mounted, the inside of the MOA can be coated with UV-reflecting or at least UV-light-impermeable material, to prevent leakage of UV-light. The MOA is preferably portable with its own energy supply (eg battery). The MOA can be attached to the body or held in the hand and can therefore be mobile. The screen itself can thus also be made lighter, which makes it possible to wear it more comfortably. The MOA can be implemented modularly, whereby different types of resources, such as filters, can be added, removed, exchanged or cleaned. Depending on the situation, MOA and air hose can be selected or purchased by the person or by e.g.

a transport company (such as an airline) can be made available. A preferably universal connection of the air hose to the screen allows easy exchange and connection. Furthermore, any functionality mentioned above (such as USB connectivity), other than the splash screen function itself, can be performed in the MOA.

The connection of the air hose of the MOA is preferably at the bottom of the screen, whereby the screen also preferably connects to the face (like a kind of diving mask). Respiration (inhalation and/or exhalation) preferably takes place via the MOA. Air can preferably be drawn in by the person through a supply air hose from the MOA and discharged through an outgoing opening from the screen.

Figure 5 shows an embodiment of a mobile disinfection device (MOA) 500 consisting of a unit 501 with an air hose 502 coupled thereto, which can be hygienically coupled to unit 501 via connector 501, preferably with one hand. Air hose 502 can be connected to the screen 100 can be attached via connection 506, so that person 200 can draw air from unit 501. Person 200 can exhale the inhaled air again via air hose 303 to the optional exhaust system as described above. The outgoing air hose is attached in the figure to the top of the screen 100 in order to make the shortest possible connection with the suction installation placed above. The in- and out-going openings in the screen 100 may also be positioned differently, as can the extraction installation. It is also possible to return the outgoing (exhaled) air to unit 501, for example via a separate supply and exhaust hose system that is provided with valves that regulate the airflow direction.

The entrance and/or exit openings 302,304,501 and/or 506 or the air hoses 502 and/or 303 can be provided with (additional) filters or a UV purifier that disinfects the air that flows past.

In this case, a UV purifier can consist of one or more UV light sources, preferably UV LEDs, which are supplied with power via an electronic circuit. The power supply can be obtained from eg MOA 500, a separate battery or another external power source. The placement of the UV LEDs is preferably such that as much as possible, preferably all air flowing past, is irradiated. Micro-organisms are then killed under the influence of UV light. Different UV frequency ranges and light intensities can be used for this. To prevent the escape of UV light (which can be potentially harmful to health if exposed to too much) through the wall of the air hoses, the inside of the air hoses is preferably wholly or partially lined with light-impermeable material. To promote the further conduction of the UV light, the coating can also be designed as a light-reflecting material, so that the light is, as it were, trapped in the air hose and does its disinfecting work more effectively there. By using a small beam angle per LED, LEDs can be used with a relatively lower luminous flux, so that sufficient light intensity is achieved in the area that is irradiated. This lowers the power consumption. A preferred arrangement of the LEDs is therefore that the LEDs are arranged in a ring of inwardly radiating UV light, so that the air forced through the ring is optimally irradiated.

LEDs can also be placed in the same ring or in a separate ring that radiate towards the center instead of perpendicular to the wall of the air hose, at an angle towards the further course of the air hose or towards the connector or connected equipment such as MOA 500. . In this way, the largest possible area inside and even partly outside the air hose can be irradiated.

Any reflective inner lining then conducts the UV light even better. In this way, such LED rings can also be placed at several places in the air hose. An additional advantage of these LED rings is that they can also be designed to provide strength to the air hose, in other words to prevent the air hose from collapsing. Instead of a ring construction, other constructions for the LEDs are also conceivable. Single or multiple LEDs can be placed at one or more places in or around the air hose (in the latter case with possible light holes in the possible inner lining). One or more UV-LED strips can also be placed in the longitudinal direction in or on the air hose, with the LEDs radiating to the interior of the air hose, even in such a way that it irradiates the entire length of the air hose.

Mounting of UV lighting should take place in such a way that leakage of air (false air) is prevented and preferably no UV light leaks to the outside world.

Unit 501 can be provided with an inlet opening 503 for air to be drawn in. Optionally, exhaled air can also be blown out via unit 501 via an outlet opening 504.

Unit 501 can be provided with one or more connectors 505 to, for example, connect external equipment. An example is a USB connection 505 into which a USB plug with cable 600 can be inserted.

Unit 501 can also be configured to insert other items for disinfection with, for example, the built-in UV sanitizer.

Unit 501 can be equipped with a fan to provide an overpressure in the screen. Preferably, a (slight) overpressure ensures that no unwanted contaminated air enters the screen along the edges. A pressure valve that opens at a very low overpressure can also be placed in the discharge for this purpose. Preferably, measures are taken that the user can never experience too much under or overpressure. One measure may be to monitor the air quality of the air to be breathed.

To ensure that as little air as possible escapes, for instance through the screen, the screen can be provided with sealing means, such as a closure attached to or around the screen, which can form an airtight seal between screen and face.

A known problem with screens and masks with a transparent part through which to look is that exhaled air causes the transparent plastic or glass plates to fog with water vapor. This is uncomfortable and in some situations highly undesirable (for example during operations) or unsafe (for example because the view of the road is obstructed). The invention therefore proposes to take a number of measures to combat condensation.

For example, the inside of the plate on which people breathe and through which a clear view is desired, can be provided with a coating that is water-repellent. Such a coating may contain ethanol as an active ingredient, making it less suitable for use on plastic. As an alternative, an anti-condensation foil can therefore be placed on the plate.

Condensation occurs because warm water vapor-containing air occupies a colder material such as the plate of the screen. The invention therefore proposes to prevent fogging by increasing the temperature of the shield plate. For this purpose, wiring can be applied to the screen, such as the heated front or rear window of a car. This very thin wiring can even be concealed invisibly. By connecting the wiring to a power source, the wiring acts as a resistor and heats up. No condensation will then take place. Optionally, a certain power can be applied to the electrostatic section 102 itself, alternating or not, to cause the wiring of the grid to function as a resistance that heats up. The heater wiring can also be done alongside or in conjunction with the electrostatic filter. Power may be provided by a battery/battery in display 100 or in unit 501.

Alternatively or additionally, the source of the condensation can also be addressed, namely the high humidity of the air flowing past the screen 100 . By building in a dehumidifier in a separate sector of unit 501, the air that is inhaled and/or the air that is exhaled via unit 501 can be dehumidified to a desired level. The moisture to be drained can be cleaned of viruses with UV and collected in a separate part of unit 501 and/or a water bottle. For example, if the ambient air already has a relative humidity of 80%, the dehumidifier can bring this down to the optimum percentage range of 40-60 percent. This percentage of humidity is more pleasant to breathe in, but also contains fewer aerosols and micro-organisms, which are known to spread more easily in aerosols (air droplets). These micro-organisms are therefore also filtered in the dehumidifier.

As a dehumidifier, a chemical type can be chosen that consists of a reservoir with crystal granules of mostly calcium chloride that are used to absorb moisture, condensation and musty odors from the surrounding air.

Another option is an electric dehumidifier, in which air is sucked in and first filtered to prevent dust particles and other contaminants from entering the device. For example, an electric dehumidifier works according to the principle of an evaporator/condenser combination or according to the principle of adsorption with a desiccant disc.

The positive effects of air dehumidification are therefore manifold: the inhaled air can be regulated at the right humidity. Less condensation will form, the inhaled air contains even fewer micro-organisms, the exhaled air contains less water vapor and therefore fewer micro-organisms and there is less risk of contamination for the environment. Finally, the electrostatic filter (and other filters such as an ionizer) can do its job better, as lower humidity gives better performance. Optimal operation usually takes place at a relative humidity between 45-60%. In general, less humid air is better for the electronics in the display 100 or in unit 501 or in the air hoses because it prevents mold and contamination with other microorganisms. For this reason, continuous UV cleaning also takes place in unit 501 until it is opened for maintenance, etc. Besides condensation, there can be other factors that affect visibility. For example, incident light can be too bright because it reflects on the plate of the screen, so that the user cannot see through the plate properly. However, the user or the environment can also place other demands on the panel. The invention therefore proposes to provide the transparent plate surface of the screen with one or more of the following features: - design the plate of the screen as a partially light-opaque plate such as sunglass lenses; - provide the plate with an anti-reflective/anti-reflective coating as often applied to spectacle lenses; - the plate is provided with an anti-scratch coating. Scratches scatter the light and thereby hinder a clear view.

- The plate is equipped with a filter function that can regulate the transmission of light. The plate can for instance be designed as a (self) dimming plate, for instance by coupling a blackout controller to a light-dimming plate such as made of electrochromatic material. The use of thermochromatic material is also a possibility, whereby the plate darkens under the influence of heat. Optionally, a sensor can be installed that measures the intensity of incident light and, depending on the strength, can darken the plate more or less.

- The plate can be coated with or consist of UV-resistant material, which gives the user extra protection in sunlight. - The plate can be provided with or consist of heat-resistant (Infrared light-resistant) material; - The screen can be equipped with a system to change plates, depending on the need. The system can also be set up to add extra plates. Thus, for example, the above plates can optionally be combined with a standard plate or with other special plates. Another special plate may be a color filter plate, allowing the user, for example, to choose a color that suits her mood or function.

Since a screen that is in the way of a person's breathing may interfere with a user's speech, additional measures can be provided to support the user's communication. The advantage is that one can speak more softly, which leads to less (strong) inhalation and exhalation, so that the screen is less effective or dirty. For example, a microphone can be placed in or on the screen. The microphone can be connected to an amplifier and a loudspeaker, for example integrated in the MOA. The user's voice can thus be amplified via the loudspeaker. It can provide advantages, for example, when giving voice commands in, for example, a car for navigation, etc. To promote that the user can also understand other people and/or hear sounds from the environment, the microphone can also be designed to to strengthen towards the user. To this end, the user can connect headphones to the amplifier. Optionally, separate microphones are provided, wherein the first microphone is directed to receive speech from the user and the second microphone is directed to receive ambient sounds. The system of microphone, amplifier and loudspeaker can also be integrated into a smartphone, whereby the smartphone can serve as an amplifier and/or as a sound receiver by means of an app. | By means of a mobile connection, the smartphone can also facilitate communication with other telephone users. The microphone can also be set up to make a (wireless) connection to the amplifier and/or the smartphone by means of a wireless connection method such as Bluetooth or Wifi.

The screen itself, a mounting mechanism to fix the screen to the head, or other parts of the proposed system such as the MOA can be provided with a holder to attach a smartphone releasably/removably.

The screen can be provided with a device so that an image from, for example, a smartphone or a beamer, such as a min-beamer, is projected onto the plate of the screen of the invention, making the plate of the screen a head up display (HUD). forms.

The screen can be provided with fastening means for fastening, for instance, a headscarf. A headscarf can also be integrated with the screen. This makes it possible for a user to combine a hijab with the screen for religious reasons, for example, without the screen's performance deteriorating.

The screen, the MOA or other parts of the security system, such as connectors, air hoses, disinfecting devices according to the invention, can be of modular design. Depending on the ambient air pollution, certain functionalities and devices can be selected and confirmed. A sensor system can be linked or integrated with the protection system, so that functionalities such as the UV light disinfection modules or the MOA can be switched on and off depending on the situation. Sensors can be set up that can measure, for example, particulate matter values or volatile organic compounds. Temperature and humidity, or for example the presence of aerosols, can also be measured by the sensors and translated into an action of the protection system or a warning for the user. A controller can also switch functionalities on and off depending on the situation, location, type of transport, or risk of contamination, etc.

Whether a functionality is enabled or not can be checked with eg visual indicators, such as lights that are on when the functionality is on. Windows can also be arranged so that the operation can be visually checked.

For example, a window in the MOA can show that a fan is in operation. The visual indicators can also be used to serve as a warning system if and as soon as a filter becomes full or needs maintenance, or the air quality drops below a certain minimum value or the risk of contamination in a certain area is high.

Warnings can also be given via the mobile communication of the protection system and can be visualized, for example, by the visual indicators of the protection system itself.

For example, a central service can give code green, yellow or red in a certain area, which can indicate a risk of contamination.

Once user enters that area, the protection system will be able to give a warning or turn itself on automatically if there is a risk of contamination.

If necessary, switching on or checking the status of the protection system can also be checked remotely by, for example, a central service.

The sensors that monitor the ambient air can also pass on their data to the central service, so that data can be collected about areas and based on that data can keep statistics or issue alarms.

Calculations and predictions based on the sensor data of the protection system can also be collected and analyzed by the central service, for example to communicate a personal protection advice to the user or the protection system, on which the user or the protection system itself can adjust settings or functionalities. disable or change.

Instead of visual indicators, text messages, sound signals or haptic feedback, such as vibration felt in the screen, can also be used. î The above functionalities can optionally be checked and communicated by and with the user by means of a software application, such as installed on a smartphone of the user.
