COVER FOR CONVERTING ELECTROMAGNETIC RADIATION IN ELECTRONIC DEVICES
First Claim
1. A method comprising:
- capturing radio frequency (“
RF”
) radiation emitted from an electronic device using an antenna;
converting the RF radiation into DC current;
outputting the DC current to an indicator circuit; and
providing an indication during times when RF radiation emitted from the electronic device is being captured.

Abstract
A method and apparatus for capturing and converting radio frequency (“RF”) radiation emitted from an electronic device are disclosed. In at least certain embodiments, the method includes capturing at least a portion of the RF radiation emitted from an electronic device and converting it into DC current that can be used for a number of different functional purposes. The electrical energy from the DC current can be used to drive an apparatus including a circuit that provides an indication as to when absorption of RF radiation occurs 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 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 RF radiation away from their bodies and dissipating it as electrical energy.
