Abstract
A radiation shield comprises a substrate polymer layer, a conductive layer having an aperture providing access to a front face of a cellular telephone, adjacent the substrate polymer layer, and an adhesion surface adjacent the conductive layer and the front face. A radiation shield comprising a first substrate polymer layer, a conductive layer having an aperture providing access to a touch-sensitive screen of the front face, adjacent the first substrate polymer layer, a second substrate polymer layer adjacent the conductive layer, and an adhesion surface adjacent the conductive layer and the front face. At least one opening provides access to the front face.
Claims23
A radiation shield for attachment to a cellular telephone, the cellular telephone having a front face and a set of controls, comprising:
- a substrate polymer layer;
- a conductive layer having an aperture providing access to the front face, adjacent the substrate polymer layer;
- an adhesion surface, adjacent the conductive layer and the front face;
- the radiation shield having at least one opening adjacent to the set of controls;
- whereby the radiation shield attenuates electromagnetic radiation.
A cellular telephone, comprising:
- a front face having a touch-sensitive screen;
- a base having a set of controls;
- a radiation shield, adjacent the base, having at least one opening adjacent the set of controls;
- and
- a cover adjacent the radiation shield and attached to the base;
- the radiation shield further comprising:
- a first substrate polymer layer;
- and
- a conductive layer, having an aperture adjacent the touch-sensitive screen and adjacent the first substrate layer;
- wherein the aperture provides access to the front face;
- whereby the radiation shield reduces a transmission of electromagnetic radiation.
A method for reducing an electromagnetic radiation level produced by a cellular telephone utilizing a radiation shield, comprising:
- providing a substrate polymer layer;
- providing a conductive layer, having an aperture providing access to a front face of the cellular telephone, adjacent the substrate polymer layer;
- removably attaching the radiation shield to the cellular telephone with an opening adjacent at least one of a set of controls and a touch-sensitive screen of the cellular telephone;
- and
- operating the cellular telephone;
- whereby the radiation shield attenuates electromagnetic radiation.
