RELATED APPLICATIONS

[0001] This application claims benefit of, and claims priority to, U.S. Patent Application No. 62/551,422, filed on August 29, 2017, the entire contents of which are specifically incorporated by reference herein.

BACKGROUND

[0002] Radiofrequency radiation from mobile phones, computers, and other electronic devices is becoming increasingly ubiquitous. Scientists and health professionals are increasingly concerned about the risks of such constant exposure, including, for example, from extremely-low frequency (ELF) magnetic fields. For example, the 2012 Bioinitiative Project, which was designed to identify standards for exposure to low-intensity electromagnetic radiation, concluded that childhood leukemia is associated with exposure to such radiation either during early life or in pregnancy.

[0003] Indeed, as wireless communications technology advances, more and more devices are crowding the airwaves with electromagnetic radiation. For instance, energy companies now routinely install power meters at residential homes where powerful transmitters relay information about customer usage. Concerns about electromagnetic radiation from power meters have risen so much that some jurisdictions have considered banning them. Conventional shielding technologies deploy metals that while they reduce errant electromagnetic radiation at higher frequency, they do not perform well at reducing ELF magnetic fields, for example. In addition, their effectiveness at high frequency tends to degrade the intensity of desirable information signals such as at Wi-Fi carrier frequencies. SUMMARY

DETAILED DESCRIPTION

[0023] An electromagnetic reduction material reduces the amount of electromagnetic radiation passing through it such, as for example, an object emanating electromagnetic radiation. The electromagnetic reduction materials of the disclosure include an inorganic salt comprising sodium salt, and in many embodiments is referred to as "Himalayan salt" or "Himalayan sea salt." Himalayan salt is rock salt or halite from the Punjab region of Pakistan and is commercially available. It typically contains between about 95% to about 98%) sodium chloride, between about 2% and 4% polyhalite (which contains potassium, calcium, magnesium, sulfur, oxygen, hydrogen), about 0.01%> fluoride, about 0.01%> iodine, and micro-amounts of numerous trace minerals. The salt crystals often have an off-white to transparent color, while impurities in some veins of salt may give it a pink, reddish, or beet-red color. As used herein, the term "Himalayan salt" does not require that the salt come from a specific region or geography, rather, that it be substantially the same composition as Himalayan salt that would be found in the Punjab region of Pakistan.

[0024] Electromagnetic reduction materials may also be said inorganic salts in combination with polymers or glass. When combined with a polymer, for example, such combinations may be in the form of sheets, encasements, plaques, or other solids. For example, the salt may be combined to form plaques that could be placed in front of an object or to encase an object in an encasement where electromagnetic reduction is desired. In many such embodiments, such inorganic salts are Himalayan salts.

[0025] Without being bound by theory, it is believed that the Himalayan salt acts as a selective absorber of electromagnetic radiation, including ELF. The Applicants have shown that electromagnetic reduction materials comprising Himalayan salt and devices made with such materials reduce and in many cases do not permit measurable extraneous and unwanted ELF radiation to pass, while at the same time permitting desired signals, such as from a Wi-Fi router, to pass. It is desirable to have an ELF absorbing material because of deleterious effects seen in exposure to ELF of intensities of only a few milligauss and higher.

[0026] Common Wi-Fi frequencies are at 2.4 GHz and 5 GHz and it is at about those frequencies that desirable data is transmitted. Generators of Wi-Fi signals, such as routers, produce radiation across a wide spectrum beyond simply the signal frequencies. For example, such devices produce ELF (extremely low frequencies) which are up to about 100 KHz and include other ranges including in the 3 to 300 Hz range. The objects and materials of the disclosure may be used to reduce ELF exposure.

[0027] In many embodiments, the Himalayan salt is adhered to the polymer or glass, often a polymer film. In such a film, the Himalayan salt may form a coating on the polymer. In some embodiments, there may be alternating layers of film sheets, such as polymer film sheets, with layers of Himalayan salt in between said alternating film sheets.

[0028] In many other embodiments, the Himalayan salt is combined with a polymer to form an object such as a plaque. Such plaques may be used alone or stacked together to act as electromagnetic reduction materials. The plaques may also be coated with one or more alternating layers of film sheets, such as polymer film sheets, with layers of Himalayan salt in between.

[0029] In other embodiments, the Himalayan salt is combined with a polymer or glass to form other solids such as an encasement. For example, the salt may be combined with a polymer at the melt temperature of the polymer and mixed and then cooled or injection molded into a solid. Injection molding may be done first by forming a different solid of the Himalayan salt and polymer such as a pellet. Ultimately, the solid formed may be in the form of an encasement. In some embodiments, the encasement polymer is acrylic. In some embodiments, the encasement polymer is PC/ABS. The encasement may then be placed around an object capable of emanating electromagnetic radiation. In many embodiments, when energized, the object emanates electromagnetic radiation and the encasement containing a polymer and Himalayan salt reduces the electromagnetic radiation, such as ELF, emanating from the object as it passes through the encasement.

[0030] Examples of polymers of the disclosure include crosslinked polyolefins, non-cross- linked polyolefins, Polyvinyl chloride, Polycarbonate-Acrylonitrile-Butadiene-Styrene blends, acrylic, polystyrene, low-density or high-density Polyethylene, Polypropylene, polystyrene, polylactic acid, poly-d-lactide, poly-l-lactide, regenerated cellulose, polyglycolic acid, plastarch material, polyhydroxybutyrate/polyhydroxyalkanoate, polycaprolactone, zein, shellac, lexan, eastman tritan, ethylene-propylene/ethylene-vinyl acetate copolymer/co-polyester/ethylene-vinyl acetate/ethylene-propylene copolymer, biaxially oriented polypropylene, nylons, teflon, polyethylene terephthalate, thermoplastic polyurethanes, mixtures of two or more of these, and mixtures of any one or more of these with one or more other polymers. Any such polymer or combination thereof may be used in conjunction with the Himalayan salt in accordance with the disclosure to reduce ELF exposure.

[0031] In embodiments where Himalayan salts are used in alternating layers with films (such as with polymer films) a typical thickness of a layer of Himalayan salt is on the order of about 1000 microns (1 mm being the particle size, for example on the label of some commercially available Himalayan salt). Typical layers of polymer film is on the order of 0.001 inches (254 microns) (a typical film being Gila® Safety and Security Film which is on the order of 0.001 inches thick). Thus, the combined thickness of such combinations is about 1254 microns. Other thicknesses of combinations are also available. For example, such thickness ranges include between about 25 microns and 250 microns, between about 250 and 500 microns, between about 500 microns and 1 millimeter, between about 1 millimeter and about 10 millimeters thick, and between 10 millimeters and 30 millimeters thick and all thicknesses in between. In many embodiments, the thickness of such a combination is at least 250 microns thick. In other embodiments, the thickness is at least 300 microns thick. In some embodiments, the thickness is between about 1000 microns and 2000 microns including between about 1000 microns and 1500 microns including between about 1200 microns and 1300 microns, and all values in between. In many embodiments, the number of combinations may be between 1 and 10 and any number in between such as 1 or at least 1 or 2 or at least 2. In particular any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 combinations may be used in such embodiments.

[0032] The density of Himalayan salt on polymer films is often between about O. lgrams per square inch and 1 gram per square inch including all values in between such as between about 0.3 and 0.5 grams per square inch and 0.4 grams per square inch. In some embodiments, the density is about 0.38 grams per square inch. The typical average thickness of the polymer film in Himalayan salt-polymer film combinations is between about 0.0001 and 0.1 inches including all values in between such as between about 0.001 and 0.1 inches and between about 0.001 and about 0.01 inches.

[0033] In many such embodiments where films are used, the polymer may be, for example, window insulation films such as a plastic film. A window insulation film is a plastic film which can be applied to glass windows to reduce heat transfer. There are two types in common use designed to reduce heat flow via radiation and convection respectively. Other films include solar control films or convection control films. A solar control film works by reflecting the infra-red component of solar energy (often 700W/M ² ) and absorbing the UV component. Some films are also silvered or tinted to reduce visible light. Typical absorption for a silvered film is 65% for visible and infrared with 99% for UV. This type of film sticks may be used to stick directly onto glass.

[0034] A convection control film is a film attached to a window frame to trap a pocket of air between the glass and the film, creating a double-glazed system with an insulating gap of still air. Thermal conductivity of still air is 0.024 W/m/K and much lower than that of glass (0.96 W/m/K). Factors which limit the performance of a double glazed window are gap width, convection within the cavity and radiative heat transfer across the gap which is largely independent of its width. Optimal gap width depends on the temperature difference imposed across the gap. A European standard (EN 673) uses a 20 °C difference between the inside and outside temperature which results in a simulated gap width of about 17 mm for a standard double glazed window. A US standard (NFRC) uses a 39 °C difference which yields a smaller gap width of about 13 mm. Using the European standard a window with a gap of 17 mm has a simulated U- Value of about 2.8 W/m ² /K, a window with a much smaller gap of 6 mm has a U-value of about 3.3 W/m ² /K, while a single glazed window has a U-value of about 5.5 W/m ² /K. The gap in such films is typically between about 1 and 100 mm thick.

[0035] The film may also be shrink wrapped, which can be useful when making an encasement with the film. The most commonly used shrink wrap is polyolefin, crosslinked, or non-cross-linked. PVC, and Polyethylene Polypropylene. Co-extrusions and laminations are available for specific mechanical and barrier properties for shrink wrapping food. For example, five layers might be a configuration of EP/EVA/co- polyester/EVA/EP, where EP is ethylene-propylene and EVA is ethylene-vinyl acetate copolymer Also, biaxially oriented polypropylene (BOPP). [0036] The films may be prepared, for example, as set forth in Figure 8. Electromagnetic reduction material 820, such as Himalayan salt, may be adhered to polymer film 810 to form alternating film layers. The adherence may be done, for instance, with a polymer film that has an adhesive on one side to with 820 is added. The non-adhesive side of an 810 film layer may then be placed in contact with the Himalayan salt already adhered to a separate 810 polymer film. When the desired number of films are obtained, the resulting polymer film - Himalayan salt layer assembly may be arranged so as to encompass (for example, arranged so as to wrap around) one or more surfaces of a desired object which generates electromagnetic radiation so as to attenuate the radiation.

[0037] Figure 9 illustrates the alternating polymer-film - Himalayan salt of Figure 8 in a partial cross-section schematic. In that schematic, a source of electromagnetic radiation 920, such as a Wi-Fi router, is encased in a polymer encasement 910 which is enveloped by alternating polymer-film - Himalayan Salt layers, with the innermost layer being Himalayan salt. Four layers of each are illustrated in Figure 9 on only one side of the encasement. Additional sides of the encasement may also be covered by said alternating polymer-film - Himalayan Salt layers, so that more or all sides (including bottom and top if desired) may be covered.

[00132] EXAMPLES

[00133] Example 1 - Adhering Himalayan Salt to a Window Film

[00134] The process of adhering salts to window films was performed with use of multiple layers of security film designed for shatter-proofing windows. The security film utilized was Gila® Safety and Security Film, clear in color, (see, e.g., Patent No. US 4,075,386) comprising a polyurethane stratum interposed between a pair of polyester strata, each of which is self-supporting, with the minor surface of the film comprising a pressure sensitive adhesive (PSA). Each PSA layer comprises a pressure sensitive adhesive to bond the Himalayan salt to each layer. One major surface of each layer is bonded to one opposite minor surface of the next subsequent layer such that the Himalayan salt is sandwiched between each layer. The thickness of the Himalayan salt being .001 inches. A photograph of a resulting film-salt base material (i.e., Himalayan salt) is set forth in Figure 1. [00135] Example 2 - ELF Performance

[00136] The film of Example 1 was applied to an acrylic box structure designed to encase a Wi-Fi router to test the ability of the salt to block both extremely low frequency (ELF) and extremely high frequency (EFIF) signals emanating from the router. The acrylic utilized was .050 Non-Glare Acrylic (manufactured by Plaskolite, Inc., Plexiglas® MC UF-5). The router tested was an Arris TG 862 dual band (2.4 and 5.0 GHz) Xfinity cable Wi-Fi router operating at full power on each channel as seen in Figure 2.

[00137] Multiple acrylic encasements were constructed, as shown in Figure 3. A total of 7 encasements were made (the seventh box is seen on the lower right-hand-side of Figure 3). The encasements in Figure 3 were subsequently wrapped with polymer film layers and Himalayan salt layers in between. The Himalayan salts used had a typical particle size on the order of about 1mm as indicated on the label. When making films, the salt was applied evenly to the adhesive surface of each film in the amount of about .38 grams per square inch. When attaching the films to the acrylic encasements, the first encasement was wrapped with one layer of film with salt adhered. Each subsequent encasement was wrapped with an initial layer of film with salt adhered and an additional layer of film with salt adhered. Thus, box 2 had 2 such layers (two of each salt an polymer film), box 3 with 3 such layers, etc. The structures measured 9 5/16" x 8 1/4" x 2 3/16". Each layer of film was measured by a General No. 102, 0-1 inch .001 Caliper, and measured .001 inches (about 25 microns) per layer. Figure 4 shows one example encasement and Figure 5 shows another example encasement from a different perspective.

[00138] Measurements were taken using a TriField® Meter, Model 100XE of both ELF and EHF with an acrylic box that was not wrapped with a layer of film. The measurements for ELF were over 100 milligauss prior to implementing any layers of film as a barrier. The tests were then performed with a layer of film added for each additional test. Measurements were taken of the first box comprising one layer of the Himalayan salt material and the ELF reduced 10 fold to 10 milligauss. It may be noted that while substantially reducing the amount of ELF, it was still possible to transmit data to and from the router for, e.g., checking e-mail, etc.

[00139] The next box was measured comprising 2 layers of Himalayan salt with

ELF measuring 3.5 milligauss. The third box was measured comprising 3 layers of salt with ELF measuring 1.5 milligauss. At four layers, ELF was not measurable, and the transmission of the EHF (the WiFi signal) was only minutely affected.

[00140] Example 3 - Preparation of router encasements containing Himalayan salts

(prophetic)

[00141] Polycarbonate-Acrylonitrile-Butadiene-Styrene Blends (AB/PCS) are prepared with Himalayan salts at concentrations of various concentrations ranging from 1% to 99%. Blends are slow or fast-injection molded at sufficient temperatures to make desired encasements.

[00142] Example 4 Testing Router Encasements of the Disclosure

[00143] An Arris Surboard Dual band router was measured with a TriField® Meter

Model 100XE meter for ELF measurements. In an AB/PCS blend containing Himalayan salts which was injected molded so as to encase the router. Concentrations from about 5% to about 20% were made. The following measurements were done on the about 10% Himalayan salt loading encasement. With the router turned on, but without a cover, the ELF was "pinned" to the highest value of the trimeter which was 100 milligauss. After putting the cover on the router, the ELF was reduced to 0.7 milligauss over the course of several hours. Upload and download speeds were measured using an app called "SPEEDTEST" (by Ookla®) and on average (three phones and two laptops) found to have a download speed of 45 Megabits/second without an encasement and 42 Megabits/second with an encasement. Without an encasement, the average upload speed was measured to be 11.1 Megabits/second which lowered to 10.1 Megabits/second with an encasement.

[00144] Example 5 - Head-to-Head Comparisons Between Encasements of the Disclosure and Commercially Available Shielding Devices

[00145] Encasements without Himalayan salts were prepared and used to encompass an Arris Surboard Dual Band Wi-Fi Router using the about 10% loading of Example 4. Both ELF, measured at between 40 Hz and 100 KHz, and EHF at 2.4 GHz were measured using a TriField® Meter Model 100XE. A Router Guard® was purchased, which is a metal mesh cage sold commercially, as a comparator. In the comparison experiments, the router was placed inside the Router Guard device. Without any encasement or Router Guard as shown in Figure 6, ELF was found to be over 100 milligauss. With the Router Guard, ELF was only slightly reduced to slightly over 90 milligauss. By comparison, with an encasement of the disclosure, ELF reduced to 1.5 milligauss after 1.5 hours and to 0.6 milligauss after 3 hours. With regards to EHF, Wi-Fi signal at 2.4 GHz was only nominally reduced to 1125 db/square meter from 1175 whereas with Router Guard, EHF was reduced from 1175 db/square meter to 596 dB/square meter as set forth in Figure 7.

[00146] Example 6 - Polymer Epoxy Plaques of Himalayan Salt

[00147] Positive plaque molds made out of modeling board material (RenShape™) with dimensions of 4x4x0.15 in plaques were sketched using computer aided drawing software (Autodesk® Fusion 360™). The molds were sanded prior to use. Mold negatives were prepared by using a heat resisting silicone formulation (Mold Max 60™); the flexible silicone mold was prepared by rapidly stirring a mixture of liquid precursor chemical ("Part A", primarily short chain silicone molecules with crosslinkable reactive sites) and liquid curing agent ("Part B", primarily crosslinking agent, catalyst, and diluent) together in a lOOOmL beaker. The mixture was prepared at a ratio of 100A:3B. Specifically, Part A was about 450-500 grams, with a corresponding amount of part B of 13.5-15 grams. Mixing was done until a uniform red color was achieved in the mixture (a few minutes typically) and then poured into the prepared positive RenShape mold. The mold was left to cure for about 24 hours and a spatula was used to slowly release the silicone from the positive mold, resulting in a silicone negative mold for epoxy. The silicone mold negatives were made to contain liquid epoxy during epoxy curing and ensure the appropriate dimensions of the final epoxy materials.

[00148] The silicone mold was sprayed with one coat of Smooth-On universal mold release and placed in the oven at about 80°C for 10 minutes. While the mold was in the oven, the epoxy mixture was formulated and prepared for curing in the mold. Three primary components were mixed: a common difunctional epoxide, diglycidyl ether of bisphenol A (DGEBA), a phenolic based curing agent (GP® 2074 from Georgia Pacific), and Himalayan salt in a plastic container was measured out so that the total mass was between 45 and 50 grams (depending on loading), with the GP2074 mixed at a ratio of 2:3 with the DGEBA, and the salt content at the correct concentration. The mixture was placed in the dual asymmetric centrifugal laboratory mixer (a Speedmixer™ by FlackTek Inc.) and mixed at 1600rpm in three 3-minute cycles with a 30 second break between each cycle. During this mixing, the silicone mold was removed from the oven and the oven temperature was increased to the epoxy curing temperature of 130°C. The mold was sprayed with a second coat of mold release and the mixture from the Speedmixer™ was added into a 250mL glass beaker which was then placed in a circulating silicone oil bath at 65°C for 12 minutes.

[00149] The temperature on the oil bath up was increased to 130°C. The silicone mold was sprayed again with universal mold release. The beaker was removed from the oil bath at 123°C and poured into the silicone mold and placed in the oven. A temperature program was run in the oven as follows: 130°C for 2 hours, then increase to 140°C, and hold atl40°C for 2 hours, increase to 145°C, and hold at 145°C for 2 hours, increase to 160°C and hold at 160°C for 2 hours, followed by a 4 hour cooling to room temperature. The cured polymer composite material housed in the silicone mold were taken out of the oven and the composite material was removed from the silicone. The composite material was then sanded until the color lightened to a transparent pink and ripples in the surface were removed.

[00150] Example 7 - Measurement of Blocks of Example 6

[00151] The plaques of Example 6 were measured as set forth in Figure 10. Signal generator 100 swept 1-100 kHz every 20 seconds while set to 20V. Lead line 160 from the signal generator were covered by rubber wire with alligator clips attached at the end to connect copper wire 120 to lead lines 110. Copper wire 102 was approximately 15 cm in length and was placed on a surface. A 10 cm by 10 cm epoxy plaque test article, 103, was placed on top of copper wire 102. An Aaronia AG F-5035 sensor for recording the magnetic field in milligauss (between 1 kHz and 100 kHz and attached to a computer with the Aaronia NF program so that the computer recorded the magnetic field data) was placed over test article 103 in a cantilevered position and was supported by insulating support 105 which was a dry erase eraser.
