Abstract
A phase oscillating device for affecting movement of a limb or a primary body includes a sensor coupled to the primary body. A physical state of the primary body is measured using the sensor. A phase angle of the primary body is determined based on the physical state measurement. The physical state measurement includes position, velocity, or acceleration. The phase angle of the primary body is filtered using a sine function. An actuator is coupled to the primary body. The actuator is triggered based on the phase angle of the primary body to provide a force or torque to assist or resist movement of the primary body. A secondary body is coupled to the primary body. The secondary body is oscillated using the actuator, which is triggered in phase with a gait step. Alternatively, a fan is coupled to the primary body and actuator to provide the oscillating force.
