Aiming at the nonlinear expansion/contraction drive problem between different cables in multi-joint cable mechanisms, a mechanical method based on non-circular gear was proposed, which could replace servo-sensing control system and minimize system’s complexity cost. A single-degree-of-freedom (DOF) bending mechanism constructed with several T-shaped components cross-shaped components. The princ...

This paper illustrate the design and realization of control drive electronics of Limited Angle brushless torque motor for position control of Scan mirror mechanism. The scan mirror mechanism is controlled for the intended limited mechanical angle within +/20deg. The control drive is designed for six selectable positions within +/20deg with an accuracy of 0.75 degree. These six selectable positi...

Ciné film and synchronized records of respiratory flow were obtained from Thoroughbred racehorses cantering on a treadmill at speeds of 9 and 11 m s-1. Horses and some other galloping and hopping mammals link their breathing and locomotion, taking exactly one breath per stride. Three theoretical mechanisms by which the movements of locomotion might drive ventilation are considered. (i) Flexion ...

The role of vagal activity, potassium concentration, and temperature in overdrive suppression of ventricular pacemakers, was studied in anesthetized dogs with and without surgical atrioventricular block. The results were as follows. (1) Overdrive of an idioventricular pacemaker during vagal stimulation was followed by a second pause. (2) Hypothermia increased the duration of the vagal and overd...

Treadmill-style locomotion interfaces for locomotion in virtual environment typically have two problems that impact their usability: bulky or complex drive mechanism and stability problem. The bulky or complex drive mechanism requirement restricts the practical use of this locomotion interface and stability problem results in the induction of fear psychosis to the user. This paper describes a n...
