Abstract
A radiation blocking device for use with a portable communication apparatus such as a cordless or cellular phone. The device has a radiation shield and a connector for attaching the shield to the apparatus. The shield is sized and shaped to reflect radiation emitted by the antenna which would otherwise strike the head of a user of the apparatus. The shield also reflects and absorbs heat emitted by the antenna, reducing the amount of such heat incident on said user's head. The shield is in the shape of an arc of circle and is preferably positioned concentrically with the antenna.
Claims52
A device for blocking electro-magnetic radiation emitted by an antenna of a portable communication apparatus, the device comprising:
- (a) a radiation shield having a perimeter;
- and
- (b) a connector to mount the radiation shield on the apparatus such that, when the device is mounted to the apparatus, the radiation shield together with the antenna defines a three dimensional region in which electro-magnetic radiation emitted by the antenna is attenuated,
- and whereby, when said apparatus is used by a user, the region is sufficiently large to encompass a head of the user.
A device for use with a portable communication apparatus having an antenna, the portable communication apparatus configured to be positioned adjacent a user's head, the device comprising:
- (a) a radiation shield for blocking electro-magnetic radiation emitted by the antenna;
- and
- (b) a connector rigidly coupled to the radiation shield, the connector adapted for mounting the device to the apparatus such that the radiation shield is positioned between the antenna and the user's head.
A device for blocking electro-magnetic radiation emitted by an antenna of a portable communication apparatus, the device comprising:
- (a) means for blocking radiation, said radiation blocking means having a perimeter;
- and
- (b) means for connecting to mount the radiation blocking means on the apparatus such that, when the device is mounted to the apparatus, the radiation blocking means together with the antenna defines a three dimensional region in which electromagnetic radiation emitted by the antenna is attenuated,
- and whereby, when said apparatus is used by a user, the region is sufficiently large to encompass a head of the user.
A device for use with a portable communication apparatus having an antenna, the portable communication apparatus configured to be positioned adjacent a user's head, the device comprising:
- (a) means for blocking radiation, said radiation blocking means adapted to block electro-magnetic radiation emitted by the antenna;
- and
- (b) means for connecting rigidly coupled to the radiation blocking means, the connecting means adapted for mounting the device to the apparatus such that the radiation blocking means is positioned between the antenna and the user's head.
