The Role of Peripheral Vision in Static Balancing

Ergonomics, 1967
Abstract A study was made to determine the role of peripheral vision in static balancing. Three groups of subjects were tested under sighted and blindfold conditions, and also under a minimal cues condition. One of these groups was trained in the use of peripheral vision and after five days achieved sighted competence under the minimal cues condition ...

Static balance and developmental coordination disorder

Human Movement Science, 2003
The development of static balance is a basic characteristic of normal motor development. Most of the developmental motor tests include a measure of static balance. Children with a developmental coordination disorder (DCD) often fail this item. Twenty-four children at risk for DCD with balance problems (DCD-BP) and 24 matched control children in the age

The static balancing of the industrial robot arms

Mechanism and Machine Theory, 2000
The paper presents some new constructional solutions for the balancing of the weight forces of the robot arms, using the elastic forces of the helical springs. The balancing is exactly realised in all points of work field by using the elastic system which contains the high pair mechanisms. For the performance study of the static balancing mechanisms, a

Research of the Static Balance for Spherical Rotor

Applied Mechanics and Materials, 2007
For spherical rotor of gyroscope and some other high speed rotor, static balance is important. The paper introduces a static balance method for spherical rotor: the position of the spherical rotor is fixed by the use of the special clamp apparatus, and then determines the unbalance mass using the electronic balance.

Static balancer for the rectilinear motion

2013 13th International Conference on Control, Automation and Systems (ICCAS 2013), 2013
This paper presents static balancers for a rectilinear motion using springs. A slider-crank mechanism is adopted as a base mechanism and is considered as a two-link and two-dof (degree of freedom) manipulator with an external load at the end-effector. The design of a gravity compensator is considered as mapping unit spring balancers to the slider-crank

Calibration Algorithm of a Spring Static Balancer [PDF]

International Journal of Precision Engineering and Manufacturing, 2018
This paper proposes a calibration algorithm of a spring static balancer to overcome uncertainties of link parameters or spring constants. The location of the spring attachment is adjusted in this paper considering unbalancing torques. Various algorithms are suggested to determine the location of the spring attachment: 1) an estimation algorithm for ...

Developmental changes of static standing balance in children

Neuroscience Letters, 2005
The purpose of the present experiment was to investigate the time course by which children aged 6-, 8- and 10-year-old adapt and maintain their static balance. Participants (N=30) were required to stand on a force platform with their eyes closed. Ten adult subjects served as a reference group.

Static and dynamic balances of patients with acromegaly and impact of exercise on balance

Pituitary, 2019
Patients with acromegaly may have balance abnormalities due to changes in body composition. We aim to compare static and dynamic balances in patients with acromegaly and healthy volunteers, and to evaluate the effects of exercise on balance in patients with acromegaly.This prospective study included 25 patients with acromegaly followed at endocrinology
