SAW torque transducers for disturbance rejection and tracking control of multi-inertia servo-drive systems [PDF]
, 2004 The paper proposes a resonance ratio control (RRC) technique for the coordinated motion control of multi-inertia mechanical systems, based on the measurement of shaft torque via a SAW-based torque sensor. Furthermore, a new controller structure, RRC plus

Mechanical Evidence of the Orbital Angular Momentum to Energy Ratio of Vortex Beams [PDF]
, 2012 We measure, in a single experiment, both the radiation pressure and the torque due to a wide variety of propagating acoustic vortex beams. The results validate, for the first time directly, the theoretically predicted ratio of the orbital angular ...

Physical and Chemical Roles of Metalworking Fluids in a Vibration-Assisted Tapping System
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2007 A vibration-assisted tapping system has been developed in which a piezoelectric-zirconate-titanate (PZT) oscillator applies small-amplitude vibrations to a workpiece and a torque transducer measures the time-evolving torque during the tapping process. To
