Controllable Training and Rehabilitation Device

Abstract

A muscle training and physical rehabilitation device is disclosed. The device is controllable by liquid based resistive units. The liquid based resistive unit utilizes either smart magnetorheological (MR) liquid whose resistance to motion can be adjusted by electromagnetism or by proportional valves with various liquids whose resistance can be controlled by an electronic signal. The MR fluid resistive units comprises a rotor supported by a bearing inside a housing, a stator mounted together with the housing to the mounting plate, and the MR liquid that flows inside the cavity formed by the vane of the rotor and chamber of the stator. The MR liquid is controlled by the applied electromagnetic field to adjust the resistance according to the exerted toque.

What is claimed is: 
     
         1 . An exercise device comprising:
 a liquid based resistive unit.
