Abstract: A pipeline breach monitor includes an electric field sensor and a signal processing unit in communication with the electric field sensor. The electric field sensor includes an upper substrate, and a plurality of electrodes embedded in the upper substrate. The electrodes are substantially parallel to each other in the upper substrate and comprise at least one sense electrode and a plurality of elongate sensor electrodes disposed around the at least one sense electrode. The signal processing unit is configured to (i) apply a voltage signal to the sensor electrodes, (ii) receive at least one measurement set comprising a measurement of a phase and a magnitude of a current generated in the at least one sense electrode and the sensor electrodes, and (iii) generate an assessment of accumulation of a substance proximate the electric field sensor from the at least one measurement set and at least one predetermined substance accumulation profile.

Abstract: A method of monitoring for the in-flight accretion of matter involves an electric field sensor applying a time-varying electric field to an engine surface of an aircraft while the aircraft is in flight. The electric field sensor is thermally-coupled and thermally-matched to the engine surface. A sensor monitor receives, in substantially real-time from the electric field sensor, at least one measurement set that includes a measurement of a phase and a magnitude of a current detected by the electric field sensor and resulting from the time-varying electric field. The sensor monitor generates an assessment, in substantially real-time, of an instantaneous accumulation of matter on the engine surface from the at least one measurement set. The sensor monitor activates an alarm upon the assessment indicating an accumulation of matter on the engine surface.
