Water Ski Binding Release Characteristics in Forward Lean

Proceedings, 2020
To reduce the risk of injury, waterski bindings should secure the foot to the ski when the likelihood of lower leg injury is low (retention) and free the foot when the likelihood of injury is high (release).

Acoustic rotation control [PDF]

, 1983
A system is described for acoustically controlled rotation of a levitated object, which avoids deformation of a levitated liquid object. Acoustic waves of the same wavelength are directed along perpendicular directions across the object, and with the ...

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

Advanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Acoustic positioning and orientation prediction [PDF]

, 1990
A method is described for use with an acoustic positioner, which enables a determination of the equilibrium position and orientation which an object assumes in a zero gravity environment, as well as restoring forces and torques of an object in an ...

Investigations towards extrapolation approaches for torque transducer characteristics

Journal of Physics: Conference Series, 2018
For torque transducers above 1.1 MNm, no traceable measurement has been possible to date. Therefore, an extrapolation method deploying measurement data from partial ranges is to be developed. Both partial and full range measurements up to 20 kN m are performed to gather data for implementing an extrapolation approach. The extrapolated data is evaluated,

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.
