Abstract: A sensor sleeve for use in detecting a failure in an article (e.g., a hydraulic hose), the sensor sleeve includes an insulator layer that separates two electrode layers. As such, the electrode layers deform to contact each other, which changes the impedance as measured across the electrode layers. The sensor sleeve is designed to change electrical impedance (resistance) due to fluid pressure initiating a hole through the sensor itself. The sensor sleeve will detect the fluid leak when the hole penetrates the sensor and brings the two elastic electrodes in contact with each other and/or the fluid, which when the fluid is conductive fluid, creates a signal path between the first electrode layer and the second electrode layer, which also changes the impedance as measured across the electrode layers.

Abstract: A sensor sleeve (10) for use in detecting a failure in an article (18) (e.g., a hydraulic hose), the sensor sleeve includes an insulator layer (12) that separates two electrode layers (14, 16). As such, the electrode layers deform to contact each other, which changes the impedance as measured across the electrode layers. The sensor sleeve is designed to change electrical impedance (resistance) due to fluid pressure initiating a hole through the sensor itself. The sensor sleeve will detect the fluid leak when the hole penetrates the sensor and brings the two elastic electrodes in contact with each other and/or the fluid, which when the fluid is conductive fluid, creates a signal path between the first electrode layer and the second electrode layer, which also changes the impedance as measured across the electrode layers.

Abstract: Methods and instruments are provided for measuring differences in fractional reflectivity changes between transverse electric (TE or s-polarized) and transverse magnetic (TM or p-polarized components of an obliquely incident light with high sensitivity and low noise. Also provided are high sensitivity, low noise methods and instruments for measuring differences in fractional reflectivity changes between R-polarized (right-circularly polarized) and L-polarized (left-circularly polarized) components of a near-normal incident light. The methods take advantage of a nulling step to minimize harmonics of the optical signal derived from a first sample. Determination of odd and even harmonics of the optical signal derived from a second sample allows determination of refractive index and optical absorption coefficient differences between two samples to be determined with high sensitivity and low noise.
