Abstract: An electric field sensor includes an insulating substrate, a plurality of electrodes, an insulator, a plurality vias, and a ground ring. The electrodes are disposed on the substrate. The insulator is disposed over the electrodes. The vias are coupled to the electrodes and extend through the substrate at a right angle to the electrodes. The ground ring is disposed around the electrodes and the vias and is configured to attenuate a sensitivity of the sensor to electric fields outwards of the ground ring.

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.

Abstract: A computer-based fibre production monitoring system includes at least one sensor, and a computer server in communication with the sensors. Each sensor is configured to provide data packets each being associated with a respective threadline and providing a measurement of at least one physical characteristic of a fibre as it is drawn past the sensor on the threadline and wound onto a bobbin. The computer server is configured to provide an analysis of the physical characteristics on a per-threadline basis and/or per-bobbin basis from the measurements. The sensor is configured as an electric field sensor, and includes an insulating substrate, non-contacting electrodes disposed on the substrate, and vias extending transversely through the substrate. The electrodes are interlaced with one another. One portion of the vias is coupled to one portion of the electrodes, and another portion of the vias is coupled to another portion of the electrodes.

CPC classification number: G01N33/365
Abstract: A device and method for measuring changes in denier, percent finish-on-yarn, interlacing of polymer fiber, and other fiber properties, in real time as the fiber is being manufactured. The device uses an electrode driven at a discrete voltage to induce a current which changes in amplitude and/or phase in response to changes in denier, finish-on-yarn and/or interlacing of a fiber. A sensing system samples the current and detects changes in the amplitude and/or phase. A computer, running an application program, quantifies the change and determines the applicable property.

Abstract: A method of monitoring the accumulation of matter on an external surface of an aircraft involves applying varying electric fields to the aircraft surface, and a sensor monitor receiving a time-series of measurements of a temperature of the aircraft surface and a phase and a magnitude of a current induced in an electric field sensor unit from the varying electric fields. The electric field sensor unit is mounted proximate the aircraft surface. The time-series of the measurements varies in accordance with the instantaneous accumulation of matter on the aircraft surface. The sensor monitor generates an assessment of the accumulation of matter on the aircraft surface from a correlation of the time-series of the measurements with at least one predetermined matter accumulation profile. Each predetermined matter accumulation profile comprises a corresponding time-series of current phase, current magnitude and temperature measurements.
