BACKGROUND

Among the known viewing systems, devices with integrated cathode ray tubes hold the leading position. The most widespread applications thereof are concentrated primarily in large numbers in television sets and computer terminals.

The increasing use of these devices and the increased presence of humans in front of them has given rise, particularly in the last decade, to a lengthy list of medical ailments produced by exposure to the radiations emitted by these devices.

The most typical components of television sets and computer terminals are based on a cathode ray tube, transformers, deflection coils and high-voltage transformers which, in addition to their specific functions, are responsible for producing a combination of radiations, magnetic fields and accumulated static energies, which impact on and are definitely harmful to humans and their environment. Numerous investigations are continuously being carried out in order to identify and list the number of ailments harmful to human beings, which these radiations generate.

These emissions are present, and present levels of risk even for example in computer terminals or televisions sets designed with "low emission level" standards (such as those contained in the Swiss MPRII type monitor).

The influence of these radiations has, through years of study of their effect on the health of humans, given rise to what is known throughout the world as the "computer syndrome/PC syndrome/Tokomosho syndrome", which covers all the main ailments, which are known up to the present time and are generated by said radiations.

After many experiments directed at blocking these radiations, particularly for those most exposed to them within computer surroundings, special clothing made with a metal mesh, which is connected to a "ground discharge" has, for instance, been created. The main drawback of this clothing is that it is completely impractical and totally disregards the most sensitive organs of our organism, which are located in our head.

Another not very effective recommendation is to limit the use of computers, for example, to work surroundings, In Japan, regulations "prohibit" pregnant women from walking through surroundings in which computers are operating. In addition, to these problems, the need has arisen to block similar radiations in space, where there is no atmosphere to protect the health of astronauts.

Under these premises, various types of special optical lenses (normally tempered) have been created, on which additional coatings or multilayer surface treatments are deposited from a vapor in high-vacuum systems; the senses are provided with "metallic" coatings, which operated as a true "metallic mesh" in order to block said radiations.

Having noted the effectiveness of these systems and attempted in many cases to amortize the large investments made in order to develop them, many designers and/or manufacturers throughout the world have directed their efforts towards adapting these processes so as to provide protection against radiations and static electricity generated, in particular, by cathode ray tubes.

Other methods of blocking these radiations have also been implemented by applying adhesive films having conductive properties to windows, glass or screens in order to obtain similar protective effects. Other benefits generated by the inclusion of these treatments (by the interposing of these treated glasses between the cathode ray tube and the viewer) were the optimizing of viewing by increasing the contrast and eliminating the harmful reflections at the viewing surface.

A large number of glass factories, factories for manufacturing medical accessories, coating laboratories, product integrators, etc., through the world, noting the enormous potential market for the supplying this type of effective protection against radiation and static currents, emitted primarily) by computer terminals and television sets, directed their efforts effectively towards the design, integration, manufacture, marketing or distribution thereof.

Throughout the world, the so-called "anti-radiation/anti-static/anti-reflection filters" ("anti-glare/anti-radiation filters") were created, which rapidly spread throughout the world on the basis of the following brand names and manufacturers: ASSIST SYSTEM, AMERICAN COMPUTER OPTICS, ACCO, POLAROID, CHAMP, ERGOVIEW TECHNOLOGIES, CURTIS, NATIONAL POWER ELECTRIC, FELLOWES, KANTEK, KENSINGTON, MEDIAMATE, MEMOREX, NORAD, OPTIM-EYESER, SUNLIGHT BRAND, SUNFLEX, etc.

An analysis of the processes for optimizing viewing or the image is omitted, since these processes are not related to the main object of the present device. Only the process relating to the effect of non-ionizing radiations of very low frequency "VLF" (from 3 to 30 kHz) of extremely low frequency "ELF" (from 30 to 300 Hz) and of static electricity will be analyzed.

All the so-called "anti-radiation/anti-static/anti-reflection filters", have a component element in their design, which is absolutely indispensable for their normal operation, namely, the grounding cable or ground conductor.

This is the element which makes it possible to "discharge" (by "potential difference and low resistance") via the physical connection to a point considered the "reference ground", the radiation and the static electricity, trapped by the conductive mesh or covering of these anti-radiation/anti-static/anti-reflection filters and converted into an "electric current".

To obtain full electrical contact, the grounding cable is normally soldered or crimped to the metal contact, which is normally soldered or crimped to one of the sides of the glass/acrylic, etc., which is provided with the conductive membrane or film.

For practical purposes, the reference grounds suitable for the normal operation of these devices ideally are those, which are provided in computer centers, buildings with special ground installations in the form of buried stakes, household or commercial installations with ground-wire terminals (third contact) connected to metal water pipes, metal structures such as window or door frames, etc.

The anti-radiation/anti-static/anti-reflection filters are provided with terminals or fastening clamps, which make it possible to establish an effective discharge contact while maintaining a closed electric circuit of low resistance.

If the contact with the discharge point is deficient or should the discharge point have conditions of high resistance (far from what is presumed to be an "ideal earth/ground"), the efficiency of the blocking of the radiations and elimination of the static electricity will also be deficient.

If the discharge circuit is opened by disconnecting the ground/discharge cable or by breaking it, the effectiveness of these filters becomes almost zero in terms of blocking radiations and eliminating static electricity.

Due to the fact that these radiations and static electricity are absolutely invisible, but their harmful effects on humans is not, it was necessary to measure them with sophisticated and costly instruments, in order to convert them into visible and measurable parameters. These measurements, in particular, provided the possibility of determining the effectiveness of the anti-radiation/anti-static/anti-reflection filters and of exponentially increasing their commercial distribution primarily due to the fact that users who interacted with devices having an integrated cathode ray tube (and who have suffered and know about the harmful effects referred to herein) could not observe and determine on the basis thereof the risks of free exposure to these radiations and static electricity and their practically complete elimination (the interposition of some anti-radiation/anti-static/anti-reflection filters assures blockages of theoretical levels of effectiveness on the order of 99.99%).

The need to massively mobilize these expressive demonstrations of effectiveness in order to be able to open up markets by making potential users aware of the existence of these radiations and of harmful static electricity resulted in the appearance of portable measuring instruments, which made commercial and technical demonstrations of anti-radiation/anti-static/anti-reflection filters possible and showed the effectiveness of the filters to block radiations and static electricity to potential users at that time.

Devices of this type for the measuring radiations ("electric field scanner") are manufactured, for instance, by KROLMAN in Toronto, Canada under the name of Model R-900. These measuring devices have been adopted by most manufacturers and retailers of anti-radiation/anti-static/anti-reflection filters throughout the world at a present cost of approximately U.S. $45.00 (forty-five dollars) each.

By the placing of their internal or external sensor element (for this type of radiation) on the surface of the cathode ray tube and then on the surface of the anti-radiation/anti-static/anti-reflection surface, measurement systems of this type make it possible to show the presence or absence of harmful radiations and static electricity by an acoustic/visual display. Another useful demonstration and measurement carried out by the use of these external indicators/meters is to measure the emissions of the cathode ray tube with an interposed anti-radiation/anti-static/anti-reflection filter and to connect and disconnect successively the grounding cable or discharge element, thus verifying the successive appearances and disappearances of the radiations and of static electricity when said electric discharge path is connected and disconnected. The ability to visualize these radiations has become the key element in the distribution and sales support of the anti-radiation/anti-static/anti-reflection filters throughout the world for all their possible applications.

The impossibility of providing each anti-radiation/anti-static/anti-reflection filter with a portable radiation measuring device, such as those mentioned above (it must be borne in mind that the costs of filters of similar performance from different manufacturers throughout the world are averaged the price of a filter, which effectively blocks harmful radiations, is less than the cost of these measuring devices), gives rise to a large number of limitations and drawbacks, of which we will point out only the most obvious ones, in order to clearly show the benefits derived from the introduction of the claimed device. First, it is impossible to supply the potential user independently (without lending, demonstrating or selling an external radiation measuring device) with the ability to select the best alternative for the discharge connection for the optimum operation of this filter. Second, if changes are made in the electric connection or the physical location of the cathode ray tube device, there can be no assurance without a measurement instrument that the anti-radiation/anti-static/anti-reflection filter is blocking the radiations. Third, if the anti-radiation/anti-static/anti-reflection filter is relocated on another separate device not having a measurement instrument, there can be no certainty that the anti-radiation/anti-static/anti-reflection filter is blocking the radiations in this new system. Fourth, if the grounding conditions at the point of connection selected for the discharge of the radiations are changed, there can be no certainty that the anti-radiation/anti-static/anti-reflection filter is blocking the radiations. Fifth, for any promotion, demonstration and sale of these anti-radiation/anti-static/anti-reflection filters, it would be necessary to have external measuring elements, which make it possible to show their effectiveness and the best manner of installing or position them. Sixth, if the discharge circuit is damaged or even cut entirely in an undetectable manner (not visible, for instance when the discharge cable is cut internally, the solder connection or attachment of the end of the discharge cable to the conductive terminal of the filter is broken, the solder or attachment of the end of the discharge cable to the terminal/pin for connection to the external ground is broken, etc.), there would be no assurance that the anti-radiation/anti-static/anti-reflection filter is blocking the radiations. Seventh, the user of these anti-radiation/anti-static/anti-reflection filters could never have an agent integrated in his viewing region, which interactively and continuously indicates whether he is being protected from the harmful radiations emitted by the integrated device, in particular, by a cathode ray tube.

Eighth, serious difficulties and costly investments result from the impossibility of distributing the anti-radiation/anti-static/anti-reflection filters at places of mass sales, where the seller wishes to sell the products presented in "gondolas" ("supermarket" sales), primarily due to the fact that: (a) the potential buying/using public is unacquainted with the radiation blocking concepts, which these systems propose, since it cannot see or interpret them in any way; (b) the potential buying/using public is unable to differentiate between the quality of the different products available on the world market, some of which cannot even be considered as anti-reflection filters (because of their deplorable quality, they are expressly prohibited by optometrists) but which, due to their "relatively low cost" (actually it is very high since, in general, they effectively serve no purpose and normally guarantee services which, by their physical construction, they cannot provide, making them clear commercial swindles, which unfortunately are distributed and confuse the market) are presented to them, confusing them; (c) manufacturers, integrators, distributors and/or retailers in the world of anti-radiation/anti-static/anti-reflection filters must invest enormous amounts of money in order to train groups in sellers and promoters in stores, companies, supermarkets, etc., who equipped furthermore with radiation measuring devices or indicators, try to teach the operating principle and effectiveness of these devices to the potential buyers and users.

Despite the effort and investment made in it, the rate of return or effectiveness of such demonstrations is very low because the "potential" buyer/user is not certain that the effect demonstrated will function in the same manner at his home, work place, etc., primarily because of the inability to integrate an indicator element, which makes it possible to verify anywhere the effectiveness of the operation of this device, in the anti-radiation/anti-static/anti-reflection filter.
