Abstract
Am RF/EMF radiation shielding device with a transparent film layer embedded or covered with radiation-blocking material configured to absorb or deflect RF/EMF/E3 F7 radiation with the ability to utilize the mobile device's touchscreen. Formed on the radiation-blocking material are partitions or gaps where the radiation blocking areas are absent. The partitions divide the radiation-blocking material into a plurality of isolated blocking areas. In one embodiment, the shielding device is a single film layer; in another, two or more film layers are stacked, registered, and separated by an insulated layer.
Claims21
An RF/EMF radiation shielding device for a mobile device with a touchscreen display that allows proper touchscreen functionality, comprising:
- a. a film layer configured to cover the touchscreen display on a mobile device, said film layer includes a top surface and a bottom surface, said film layer being made of a material sufficiently transparent to allow visibility of said touchscreen display used on said mobile device;
- and,
- b. a radiation-blocking material embedded or covering said film layer, said radiation-blocking material configured to block or attenuate RF/EMF radiation and,
- c. wherein said RF/EMF radiation-blocking material comprises a plurality of isolated radiation-blocking areas, each said radiation-blocking area being separated from each other by partitions in which said RF/EMF radiation-blocking material is absent.
An RF/EMF radiation shielding device for a mobile device with a touchscreen display that receives and transmits RF/EMF radiation, comprising:
- a film layer configured to cover a touchscreen display on a mobile device, said film layer includes a top surface and a bottom surface, said film layer being made of RF/EMF non-blocking material and being sufficiently transparent to allow visibility of said touchscreen display, said film layer includes;
- a plurality of shapes made of RF/EMF radiation-blocking material extending from said top surface to said bottom surface of said film layer;
- and,
- wherein said RF/EMF radiation-blocking material being configured into a plurality of isolated radiation-blocking areas separated from each other by areas in which said RF/EMF radiation-blocking material is absent.
An RF/EMF radiation shielding device for a mobile device with a touchscreen display that receives and transmits RF/EMF radiation, comprising:
- a. a film layer configured to cover a touchscreen display on a mobile device, said film layer includes a top surface and a bottom surface, said film layer is made of material sufficiently transparent to allow visibility of said touchscreen display when said film layer is placed over said touchscreen display;
- and,
- b. a plurality of radiation-blocking areas each made of RF/EMF radiation-blocking material located on said top surface and said bottom surface of said film layer, said radiation-blocking areas on said top surface and said bottom surface being separated from each other by areas of said film layer in which said RF/EMF radiation-blocking material is absent.
