Cover for converting electromagnetic radiation in electronic devices
First Claim
1. A method comprising:
- capturing at least a portion of radio frequency (“
RF”
) radiation emitted from an electronic device using a first antenna separate from a second antenna of the electronic device;
diverting the captured RF radiation away from a user and converting it into electric current using a conversion circuit so that the user is protected from exposure to a portion of the RF radiation emitted from the electronic device;
feeding the electric current into an indicator circuit, wherein the indicator circuit provides an indication to the user when the RF radiation emitted from the electronic device is being diverted; and
activating and deactivating the indicator circuit based on user-controlled input.

Abstract
Methods and apparatuses for capturing at least a portion of the radio frequency (“RF”) radiation emitted from an electronic device or other external sources and converting it into electric current that can be used for a number of different functional purposes including to drive a circuit that provides an indication when the RF radiation is captured and its relative intensity. One of the advantages of these techniques is that users can be protected from the potential harmful effects of long-term exposure to the RF radiation emitted from electronic devices, particularly for wireless phones which are often held in close proximity to a user'"'"'s body. The indication can provide users with an indication that the circuit is redirecting the RF radiation away from their bodies and dissipating it as electrical energy.

11. A cover for an electronic device comprising:
-
a first antenna embedded into the cover separate from a second antenna of the electronic device, the first antenna configured to capture at least a portion of radio frequency (“
RF”
) radiation emitted from the electronic device;a conversion circuit electrically coupled with the first antenna, the conversion circuit configured to divert the captured RF radiation away from a user and convert it into electric current so that the user is protected from exposure to a portion of the RF radiation emitted from the electronic device; an indicator circuit configured to receive the electric current from the conversion circuit and to provide an indication to the user when the RF radiation emitted from the electronic device is being diverted; and a selection mechanism to activate and deactivate the indicator circuit based on user-controlled input. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
