摘要： An adaptive energy absorption system for a vehicle seat is disclosed, utilizing an adaptive energy absorber or variable profile energy absorber (VPEA) for mitigating occupant injury due to extreme vehicle movement (e.g., during a vehicle shock event), and/or for mitigating vibration experienced by an occupant of the vehicle seat during normal vehicle operating conditions. The adaptive energy absorption system achieves the aforementioned objectives for a wide range of occupant weights and load levels. Various configurations of dual-goal energy absorption apparatuses that enable both shock mitigation and vibration isolation are disclosed.

摘要： 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.

摘要： A MagnetoRheolocial Fluid Elastic (MRFE) lag damper system for adaptive lead-lag damping of helicopter main rotors. Embodiments include snubber dampers especially for hingeless helicopter rotors, and concentric bearing dampers. The snubber lag dampers include a flexible snubber body defining a cavity, a flexible or rigid interior (e.g., center) wall subdividing the cavity, and a flow valve in the interior wall or external to the cavity. The flexible snubber body may comprise elastomeric materials and metal rings stacked together to create a sealed MR fluid cavity. The shear deformation of the snubber body induces MR fluid flow through the valve, controlled by a magnetic field in the valve. An MRFE concentric bearing damper is also disclosed, comprising a pair of concentric tubes with elastomeric material injected and cured in an annular gap between the two tubes, and an MR fluid reservoir with piston-mounted MR valve housed inside the innermost tube.
