EMF radiation protection devices
An Electric and Magnetic Fields (EMF) protection device, includes: a metallic bottom; a metallic side extending from the metallic bottom; and a top opening, wherein the metallic bottom and the metallic side form a cylinder enclosure configured to substantially block a signal passing through the metallic side and the metallic bottom and allow the signal to pass only through the top opening.
1. An Electric and Magnetic Fields (EMF) protection device, comprising:
a metallic bottom;
a metallic side extending from the metallic bottom;
a top opening, wherein the metallic bottom and the metallic side form an enclosure configured to substantially block a signal passing through the metallic side and the metallic bottom and allow the signal passing through the top opening; and
a non-metallic closure covering the top opening, wherein an enhancement formed at the non-metallic closure, wherein the enhancement is of a directional open cone extending inward.
2. The EMF protection device of claim 1 , further comprising:
a combination of metallic and non-metallic materials covering part or entirety of the top opening.
3. The EMF protection device of claim 1 , further comprising:
a pattern of the metallic bottom and the metallic side comprises a wire mesh or a metal plate.
4. The EMF protection device of claim 1 , further comprising:
multiple enhancements formed at the non-metallic closure and arranged in an array, wherein the enhancements form a cone array comprising multiple cones.
5. The EMF protection device of claim 4 , wherein each cone has a diameter of 0.1 inches to 5 inches.
6. The EMF protection device of claim 4 , wherein each cone has a depth of 0.1 inches to 5 inches.
7. The EMF protection device of claim 1 , further comprising:
a base structure comprising an extended portion extending out of the metallic bottom.
8. The EMF protection device of claim 7 , wherein the base structure comprising conducting materials including Mn, Zn, Al, Cu, Fe, or a combination thereof.
9. The EMF protection device of claim 1 , where a material of at least one of the metallic bottom and the metallic side comprise conducting materials including Mn, Zn, Al, Cu, Fe, or a combination thereof.
10. The EMF protection device of claim 1 , where the shape of the EMF protection device is a cylinder, cone, sphere, or any combination thereof.
11. The EMF protection device of claim 1 , wherein the metallic bottom, the metallic side, and the top opening form a telescopic cylinder.
12. The EMF protection device of claim 11 , wherein an area of the metallic bottom is larger than that of the top opening.
13. The EMF protection device of claim 1 , wherein the EMF protection device is configured to surround a wireless device or wireless devices including a cellphone, a tablet, or a wearable device.
14. The EMF protection device of claim 13 , further comprising:
a wired or wireless charger configured to charge the battery of the wireless devices placed inside the EMF protection device.
15. The EMF protection device of claim 1 , further comprising:
a lighting configured to serve as a lamp or a night light.
16. The EMF protection device of claim 1 , further comprising:
a position sensor configured to alert the user in response to the EMF protection device is placed in a wrong direction.
17. The EMF protection device of claim 1 , wherein the signal is a cellular, WiFi, or Bluetooth signal.
18. The EMF protection device of claim 1 , further comprising:
a housing; and
sections of a retractable body, wherein the EMF protection device is configured to be movable along a depth direction from a retracted position in which the sections of the retractable body are all contained by the housing, a semi-extended position in which parts of the sections of the retractable body are contained by the housing, and a fully extended position in which all sections of the retractable body extend upwardly.
