ABSTRACT:
A swing includes a swing motor and an adaptive control system for periodically actuating the swing motor to sustain swinging pendulum movement of a seat along a swing arc in a manner that is compatible with the natural frequency (and period) of the seat. The swing further includes a support stand and a swing seat frame mounted on the support stand to carry the seat. The adaptive control system includes an impulse mechanism that applies a torque to the swing seat frame and that is actuated at a variable point along the swing arc between first and second extreme positions and without regard to the position of the swing seat frame relative to the support stand.
