Abstract: A sensor system for analysis of forces and motions on a rotating shaft using non-contact magneto-elastic sensors with the ability to measure any one or more of the following parameters of the shaft: (1) torque, (2) rate of change of torque, (3) shaft speed, (4) shaft position, (5) bending moments in the shaft in 2 directions, (6) axial force, (7) shaft power and/or system efficiency. The sensor system generally includes a magneto-elastic sensor patches fixedly applied to the rotating shaft, and a magnetic field pick up surrounding both said shaft and said magneto-elastic material but not in contact therewith, said magnetic field pick up comprising a clam-shell toroidal collar incorporating a combination of a magnetic field sensors.

Abstract: A system for in-situ near-real-time detection and monitoring of corrosion in structures with the ability to directly track the presence and growth of corrosion on a structure by measurement of material loss in the structure attained by analysis of high frequency wave propagation dynamics. The Corrosion Inspection and Monitoring (CIM) system utilizes low-weight in-situ transducers and unique data reduction software for detection and monitoring of corrosion in structural systems in near real-time for corrosion related damage. The CIM system provides a corrosion monitoring and tracking tool that can be deployed in the field with the structural system, and no maintenance personnel are needed for corrosion analysis.
