in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...

OBJECTIVE To determine whether an impedance threshold device, designed to enhance circulation, would increase acute resuscitation rates for patients in cardiac arrest receiving conventional manual cardiopulmonary resuscitation. DESIGN Prospective, randomized, double-blind, intention-to-treat. SETTING Out-of-hospital trial conducted in the Milwaukee, WI, emergency medical services system. ...

This paper is concerned with the reconstruction of an unknown impedance p(x) in the Sturm-Liouville problem with Dirichlet boundary conditions, when only a nite number of eigenvalues are known. The problem is transformed into a system of nonlinear equations. A solution of this system is enclosed in an interval vector by an interval Newton's method. From the interval vector, an interval function...
