Abstract
A method and apparatus for discriminating between electric field sources. In one embodiment, the apparatus comprises a mobile detection system comprising a sensor probe for remotely measuring an electric field generated by an electric field source in a patrolled area; and a processor, coupled to the sensor probe, for processing data received from the sensor probe to generate a first field strength and at least a second field strength for determining whether the electric field source is potentially hazardous.
Claims20
An apparatus for identifying hazardous electric field sources, the apparatus comprising:
- a mobile detection system comprising:
- a sensor probe for measuring an electric field generated by an electric field source and producing one or more electrical signals representative of strength of the electric field;
- a processor for executing computer-executable instructions, stored on a memory coupled to the processor, the instructions comprising:
- processing the one or more electrical signals to generate a plurality of field strengths, wherein each field strength of the plurality of field strengths is indicative of strength of the electric field at a different frequency, and wherein the plurality of field strengths comprises a first strength at a first frequency and a second strength at a second frequency that is a harmonic of the first frequency;
- and
- a display that displays, based on the plurality of field strengths, an indication of the relative values of the plurality of field strengths.
A method for identifying hazardous electric field sources comprising:
- measuring, via a sensor probe coupled to a vehicle, an electric field generated by an electric field source to produce one or more electrical signals representative of strength of the electric field;
- determining, by a processor and based on the one or more electrical signals, a plurality of field strengths, wherein each field strength of the plurality of field strengths is indicative of strength of the electric field at a different frequency, and wherein the plurality of field strengths comprises a first strength at a first frequency and a second strength at a second frequency that is a harmonic of the first frequency;
- and
- displaying, by a display and based on the plurality of field strengths, an indication of the relative values of the plurality of field strengths.
