Abstract: A biomimetic miniature underwater acoustic sensor is proposed and analyzed for the measurement of directivity of underwater sound propagation. Unlike a hydrophone array, which detects propagation direction by the arrival ...

Abstract: Precise image capture using a mechanical scanning endoscope is framed as a resonant structuraldeflection control problem in a novel application. A bipolar piezoelectric selfsensing circuit is introduced to retrofit the ...

Abstract: A run-to-run optimization controller uses a reduced set of measurement parameters, in comparison to more general feedback controllers, to converge to the best control point for a repetitive process. A new run-to-run ...

Abstract: A set of protocols was created to characterize prosthetic liners across six clinically relevant material properties. Properties included compressive elasticity, shear elasticity, tensile elasticity, volumetric elasticity, ...

Abstract: Forward-viewing catheters and scopes for diagnosing disease and guiding interventions in small ducts (less than 3 mm diameter) require wide-field high-quality imaging since scope tip bending is difficult and ineffective. ...
