    Abstract: An inductance coil sensor in which a rotating spoiler (46) alters the inductance of a stationary coil (1230/1432) having two parts (12a, 12b; 30a, 30b/14a, 14b; 32a, 32b) disposed on opposite sides of the spoiler. Changes in inductance of the stationary coil are sensed to develop an indication of the rotary movement of the spoiler which, in turn, represents changes in the parameter being monitored. By locating one part of the stationary coil above the spoiler and one part below the spoiler, compensation is provided for undesired movements of the spoiler along its rotation axis.

    Abstract: Disclosed is a system for determining a material identity of a fluid being stored in a vessel, the system comprising: at least two acoustic sensors positionable substantially on an exterior sidewall of the vessel having the fluid therein, wherein the two acoustic sensors are positioned at predetermined heights on the vessel; and a computerized device in communication with the at least two acoustic sensors, wherein a processor of the computerized device receives a detection signal from one or more of the at least two acoustic sensors, wherein the computerized device uses the detection signal and measured information of the fluid to derive a temperature-compensated acoustic metric of the fluid which is compared against a material properties database to determine the material identity of the fluid within the vessel. Also disclosed is a system for determining a condition of a vessel wall, the system comprising: a vessel containing a fluid; first and second acoustic sensors positionable substantially on an exterior sidewall of the vessel, wherein first and second sensors are positioned at a predetermined height on the vessel, and wherein the second acoustic sensor is positioned angularly relative to the vessel wall; and a computerized device in communication with the two acoustic sensors, wherein a processor of the computerized device receives a detection signal from the first and second acoustic sensors, wherein the detection signal from the first acoustic sensor is used to determine a vessel wall thickness and the detection signal from the second acoustic sensor provides an attenuated signal, wherein the condition of the vessel wall is determinable based on the wall thickness and an amount of attenuation in the attenuated signal.

    Abstract: A method using Infrared Imaging Polarimetry for detecting the presence of foreign fluids on water comprises estimating an expected polarization response for a foreign fluid desired to be detected. Oil from an oil spill is one such foreign fluid. An optimal position of a polarimeter to take images of the water's surface is determined from the expected polarization response. The polarimeter is positioned at the optimal position and records raw image data of the water's surface to obtain polarized images of the area. The polarized images are corrected, and IR and polarization data products are computed. The IR and polarization data products are converted to multi-dimensional data set to form multi-dimensional imagery. Contrast algorithms are applied to the multi-dimensional imagery to form enhanced contrast images, from which foreign fluids can be automatically detected.
