Exercise apparatus and method with selectively variable stabilization enabling a user to progressively increase his/her core body muscular strength. In various embodiments, the exercise apparatus includes a resistance cabling system providing a user defined line of motion, and a partial stabilizer pad being adjustably positionable offset from the line of motion, wherein the user's core body is positionable against the pad and required to resist the torque created by the offset. The user can progressively increase the distance between the line of motion and partial stabilizer pad, in order to progressively increase the force which the user's core body must resist to maintain an upright stature. In this way, the user can progressively, over time, increase his or her core body strength. A vertically and rotatably adjustable handle/arm assembly, resistance cabling and pulley assembly, and an overall exercise apparatus having a relatively small footprint but allowing multiple variable exercise routines, are also provided.

A multi-mode mobility micro air vehicle (MAV) accomplishes ground locomotion by hopping on a retractable leg. The hopping is translated into forward locomotion when aided by the forward thrust of propellers, and the orientation of locomotion is directed by aerodynamic controls like ailerons, rudders, stabilators, or plasma actuators. The foot of the leg is convexly curved so as to produce hopping that is statically and passively dynamically stable. The MAV is also equipped for vertical takeoff so that it may conduct multiple idling missions in sequence and may return home for recovery and reuse. Structural integration of power storage and photovoltaic generation systems into the aerodynamic surface of the MAV lightens the weight of the MAV while also providing a strong structure and permitting the MAV to harvest its own energy. The MAV may autonomously conduct surveillance missions and/or serve as a flying platform for self-healing sensor or communications networks, especially when multiple MAVs are used in concert.

A stabilizer system provides leveling for a towed harvester vehicle. The harvester includes a hitch having a gimbal mounting to the tractor. The subframe is utilized to accommodate the gimbal and provides for utilizing the mass of the tractor to react to the stabilizer system leveling forces. The harvester utilizes telescoping assemblies that are placed intermediate the hitch and the frame as well as between the axle and the frame. The telescoping assemblies retract and extend to varied positions and provide correction. Flow to extend and retract the telescoping assemblies is provided through a proportional pendulum type valve that increases flow as needed when tilted from horizontal. The flow is increased and decreased in proportion to the amount of tilting from the home vertical position.
