A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s).

Walking and balance exercise device

A pelvic support unit is coupled to a base by a powered vertical force actuator mechanism. A torso support unit, which is affixed to the patient independently of the pelvic support unit, is connected to the base by one or more powered articulations which are actuable around respective axes of motion. Sensors sense the linear and angular displacement of the pelvic support unit and the torso support unit. A control unit is coupled to these sensors and, responsive to signals from them, selectively control the displacement actuator and articulation(s). Wheel modules are independently powered to both rotate and steer, and, responsive to the control unit, are capable of rolling the exercise device in a direction of travel intended by the patient.

A method and system for controlling an intelligent assist device, robot, or other powered system that is partially or fully directed by the intent of a human operator. The method and system includes measuring a force or motion imparted by the human operator to a control. The measurement is determined with respect to the motion of the machine at a point of the machine that allows the benefit of collocation of sensing and actuation, or of approximation of such collocation. The system includes a support attached to the machine at the beneficial point, and a plurality of sensors to measure the force, torque, or motion imparted by the human operator to the support with respect to the beneficial point. The method and system provide improved stability of control of the system, and improved responsiveness to the intent of the human operator.

The present invention provides an active control system for coupling the movements of a pair of independently operated manual input devices such as dual flight control sticks operated by a pilot and co-pilot flying an aircraft. Each input device is configured to receive manual input data in the form of angular displacement of the device about one or more rotational axes. The active control system provides desired tactile feedback to an operator who displaces one of the manual input devices in the form of a restorative centering force. If an external system such as an auto-pilot system is engaged, the restorative force may be in a direction necessary to reconcile manual displacement of the input device with a position commanded by the external system, rather than directed toward the center position. The system also acts to reflect manual displacement of each input device as a force applied to the other. For example, when a pilot moves his or her control stick forward, the co-pilot will feel a like force tending to move the co-pilot's control stick forward.
