Abstract
A method for sensing an electric field includes processing digitized electric field signals, e.g., from an electric field sensing probe. The processing may include performing a Fast Fourier Transform of the digitized electric field signals to provide an indication of the magnitude of the electric field, and may include processing the digitized electric field signals at a rate that is related to the speed at which a movable sensing probe is moving. The method may include performing unweighted and/or weighted averaging in relation to processing electric field data, setting a comparison threshold, providing a human perceivable indication, or a combination of the foregoing.
Claims23
A method for sensing an electric field comprising:
- receiving a digitized representation of an electric field sensed by a movable electric field sensing probe;
- sensing a speed at which the movable electric field sensing probe is moving;
- processing the digitized representation of the electric field at a rate that is related to the speed at which the movable electric field sensing probe is moving for defining a threshold;
- performing a Fast Fourier Transform on the digitized representation of the electric field at a rate that is a multiple of the expected frequency of the electric field;
- and
- comparing the Fast Fourier Transformed digitized representation of the electric field with the threshold to provide a human perceivable indication of the electric field.
