Radio frequency radiation shield device
Last updated:
Abstract:
A radio frequency radiation shield device may comprise a receiver for detecting a near field radio frequency signal at target frequencies. The shield device may further comprise a signal processor that samples signal characteristics of a detected signal and determines a nullifying signal in response to detecting a signal characteristic of the detected signal meeting a trigger threshold. The nullifying signal may comprise a modulated version of the detected signal. The shield device may further comprise a signaler for generating the nullifying signal. The shield device may further comprise a transmitter for transmitting the nullifying signal at target signals.
