Effects of Sensor Types and Angular Velocity Computational Methods in Field Measurements of Occupational Upper Arm and Trunk Postures and Movements [PDF]

open access: yesSensors, 2021
Accelerometer-based inclinometers have dominated kinematic measurements in previous field studies, while the use of inertial measurement units that additionally include gyroscopes is rapidly increasing.

A phase-to-intensity strategy of angular velocity measurement based on photonic orbital angular momentum [PDF]

open access: yesNanophotonics, 2021
Recently, orbital angular momentum (OAM) has been adopted to measure the shape of static objects and the translation motion of moving objects in optical remote sensing. Most of these studies rely on measuring the intensity variation of OAM beams. However,

The Utility of Angular Velocity During Back Squat to Predict 1RM and Load–Velocity Profiling [PDF]

open access: yesSensors
Linear velocity is commonly used to estimate 1-repetition maximum (1RM) from a load–velocity profile (LVP), as well as prescribe training intensity. However, no study has assessed angular velocity, which may be more representative of joint motion.

Optimal Rotational Angular Velocity Determination Method Based on Compound Rotary Semi-Strapdown Inertial Navigation System [PDF]

open access: yesSensors, 2022
Single-axis rotation modulation (SRM) still accumulates errors in the roll axis direction, which leads to the navigation accuracy not meeting the requirements of guided missiles. Compound rotation modulation (CRM) superimposes one-dimensional rotation on

Trunk angular velocity: A convenient, valid and responsive substitute for force plate-based measures of dynamic postural stability. [PDF]

open access: yesPLoS ONE
ObjectiveDeficits in dynamic postural stability are associated with increased risk of lower limb injuries. Objective dynamic postural stability assessments typically require force plates, which are not commonly available in the clinic.

Study on Design of Non-Circular Gears for Speed Control of the Squid Belly Opening and Gutting Machine (SBOGM)

open access: yesApplied Sciences, 2021
Non-circular gears can maintain rotational motions of general gears and implement all varying rotational motions of the cam. They adjust the angular velocity of driven gear according to operating conditions and make precise changes in angular motion. The

Attitude Control for a Rigid-Body With Dynamic Disturbance Based on Angular Velocity Observer

open access: yesIEEE Access, 2022
In this paper, we propose a geometric control law for attitude robust control problem of a rigid body system without angular velocity measurement. We suppose there is a disturbance related to angular velocity and attitude in the system. Under appropriate
