Patent ID: 7945213

Claim:
A portable device for detecting a radio frequency transmission of electromagnetic radiation, wherein the portable device comprises: a housing; a controller situated within the housing; memory communicatively connected to the controller; an antenna connected to the controller and configured to receive the radio frequency transmission; and an audio-generating component connected to the controller, wherein the radio frequency transmission of the electromagnetic radiation is harmful to an electrical device; wherein the electromagnetic radiation harmful to the electrical device is from a transient electromagnetic device (TED) threat source; wherein the controller is operative for: sensing at least one of magnitude, duration, and repetition of the radio frequency transmission; identifying a class of a plurality of different classes of the radio frequency transmission based on one of the magnitude, duration, and repetition associated with the radio frequency transmission; and causing the audio-generating component to output one or more tones of at least one of predefined frequency, predefined duration, and predefined repetition associated with the identified class of the radio frequency transmission, whereby the one or more outputted tones provide aural discrimination of the identified class of the radio frequency transmission received by the portable device; and wherein the identified class is a transient electromagnetic pulse signal from the transient electromagnetic device (TED) threat source.
