The measurement of instantaneous angular speed
Mechanical Systems and Signal Processing, 2005Many different methods have been developed for the measurement of angular speed. Each successive method has attempted to improve measurement performance using a different strategy to process encoder signals based on two basic principles: counting the number of pulses in a given time duration and measuring the elapsed time for a single cycle of encoder ...

Angular momentum of walking at different speeds
Human Movement Science, 2010Recently, researchers in robotics have used regulation of the angular momentum of body segments about the total body center of mass (CoM) to develop control strategies for bipedal gait. This work was spurred by reports finding that for a "large class" of human movement tasks, including standing, walking, and running the angular momentum is conserved ...

A robust capacitive angular speed sensor
IEEE Transactions on Instrumentation and Measurement, 1998This paper presents a contactless capacitive angular speed sensor for automotive applications. The sensor is based on a passive rotating electrode placed between two mechanically static and electrically active electrodes. The different characteristics of the charge transfer at various sensor positions is utilized as an input for the calculation of the ...

Low speed lifting cable diagnosis using instantaneous angular speed
Journal of Mechanical Science and Technology, 2021This paper describes an experimental study of lifting cable fault diagnostic based on instantaneous angular speed (IAS) technique. During the study load tests on a selection of damaged cables, it is shown that IAS increases significantly after the damage is inflicted.

In situ detection of a cooperative target's longitudinal and angular speed using structured light.
Optics Letters, 2019Laser remote sensing represents a powerful tool that enables the accurate measurement of the speed of moving targets. Crucially, most sensing techniques are two-dimensional (2D) and only enable direct determination of the speed along the line of sight ...

A model of visual detection of angular speed for bees
Journal of Theoretical Biology, 2009A fly or bee's responses to widefield image motion depend on two basic parameters: temporal frequency and angular speed. Rotational optic flow is monitored using temporal frequency analysers, whereas translational optic flow seems to be monitored in terms of angular speed.

Hydrodynamic performance of a vertical axis tidal current turbine with angular speed fluctuation
Ships and Offshore Structures, 2019The angular speed of Vertical axis tidal current turbines (VATTs) should undulate in one periodic rotation given their inherent special structure. A coupled dynamic numerical simulation method is presented to study the effect of angular speed fluctuation
