Title:
METHOD FOR SENSING AN ELECTRIC FIELD
Document Type and Number:
WIPO Patent Application WO2006071571
Kind Code:
A3
Abstract:
A method (220) for sensing an electric field includes processing (220) digitized electric field signals, e.g., from an electric field sensing probe (110), (110'). The processing (220) may include performing a Fast Fourier Transform (224) of the digitized electric field signals to provide an indication of the magnitude of the electric field, and may include processing (400) the digitized electric field signals at a rate that is related to the speed at which a movable sensing probe (110), (110') is moving. The method may include performing unweighted and/or weighted averaging (228), (231) in relation to processing electric field data, setting a comparison threshold, providing a human perceivable indication, or a combination of the foregoing.
