摘要： Methods and systems are provided for detecting presence of a target particulate of predetermined size (e.g., engine wear debris) in a fluid (e.g., an engine lubricant) by providing at least one pair of serially fluid-connected upstream test and downstream reference filtration elements in the fluid. At least the upstream test filtration element has a filtration size rating that is sufficient to remove a predetermined amount of the target particulate from the fluid. The differential pressure of the fluid may then be measured (e.g., by suitable pressure transducers) across each of the test and reference filtration elements. By comparing the differential pressure across the test filtration element to the differential pressure across reference filtration element, the presence of the target particulate in the fluid can thereby be detected by an increase in differential pressure across the test filtration element in comparison to the differential pressure across the reference filtration element. The methods and systems of the invention thus allow for the detection of target particulates that is independent of the fluid flow rate and/or temperature (viscosity, density).

摘要： High friction and radar attenuating coating formulations are provided and include a resin matrix, a particulate friction additive dispersed in the resin matrix in an amount sufficient to achieve a minimum coefficient of friction according to MIL-PRF-24667B(SH), and a particulate dielectric filler dispersed in the resin matrix in an amount sufficient to achieve a permitivitty (∈′) of less than about 10 and a loss tangent (tan δ) of less than about 0.05. A substrate surface may be coated with the coating formulation so as to provide a topcoat layer thereon. The topcoat layer may thus be applied directly onto the substrate surface. Alternatively, the coating formulation is present as a topcoat layer component of a coating system on the substrate which further comprises an intermediate layer interposed between the topcoat layer and a surface of the substrate and/or a primer layer coated directly onto the surface of a substrate between the topcoat layer and the substrate. In some embodiments, the coating formulation is applied so as to form a series of substantially parallel ridges having a predetermined directional orientation. In certain preferred embodiments, the coating formulation is applied to a block area on the substrate surface comprised of plural areal regions, wherein the directional orientation of the substantially parallel ridges of one areal region are angularly biased with respect to the directional orientation of the substantially parallel ridges of an adjacent areal region.

摘要： Sensors, methods and systems detect physical effects (e.g., corrosion, erosion, scaling and/or oxidation) of a fluid in contact with a diaphragm associated with a sensor assembly. The diaphragm preferably exhibits a first mechanical response when initially placed into contact with a fluid and a second mechanical response different from the first mechanical response after exposure to the fluid for a predetermined period of time. A change in the diaphragm mechanical responses between at least the first and second mechanical responses is therefore indicative of physical effects on the diaphragm over time caused by the fluid in contact therewith. A mechanical response sensor is operatively associated with the diaphragm so as to measure the change in the diaphragm mechanical responses and thereby determine the physical effects over time of the fluid in contact with the diaphragm. In some embodiments, the diaphragm is actuated due to a pressure condition exerted by the fluid or in other embodiments the diaphragm is internally actuated. Internal actuation includes pneumatic, hydraulic or piezoelectric means for producing a mechanical response of the diaphragm. In one embodiment, therefore, fluid corrosivity may be sensed by bringing a sensor assembly having a pressure-actuated diaphragm into contact with a corrosive fluid, exerting a pressure condition on the diaphragm so as to cause the mechanical response of the diaphragm, measuring the diaphragm deflection or strain, and then deriving fluid corrosivity from the measured diaphragm mechanical response.

摘要： Sensor assemblies, units and methods are provided to determine crack development of components of interest associated with a monitored structure. According to preferred embodiments, a sample sensor bolt is provided having a shank with a threaded end, the sensor bolt being formed of a material serving as a surrogate of the material forming a component of interest associated with the monitored structure. A frame surrounds the shank of the sensor bolt and has fluid ports therein to allow fluid to contact an exposed portion of the sensor bolt shank in registry therewith. A load cell is operatively connected to the sensor bolt. A preload nut is threaded onto the threaded end of the sensor bolt shank and contacts an end of the frame so as to place the sensor bolt under an initial tensile stress. Crack formation within the sensor bolt shank caused by fluid acting upon the exposed portion thereof responsively relieves the initial tensile stress of the sensor bolt which is thereby sensed by the load cell, whereby crack formation in the shank can be used to sense the propensity for crack development in the component of interest associated with the monitored structure.
