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.

The stabilizer works with any conventional cruise control (CC) and permits automatic CC in slower heavy traffic as it eliminates laborious frequent manual actuation of CC control buttons otherwise needed in such heavy traffic. More frequent automatic CC operation at slower speeds increases fuel efficiency. When the vehicle maintains a speed above a minimum speed and exceeds a brief preset period, the speed stabilizer sets the cruise control at that speed. When the cruise control is thus engaged, the driver's foot can move the accelerator pedal within a small tolerance range without canceling the cruise control. When the pedal is close to the bounds of the tolerance range, a warning signal such as a flashing LED display, is generated by the speed stabilizer to inform the driver that further movement of the pedal will cause acceleration / deceleration, automatically canceling cruise control. Actuation of conventional CC control buttons restores conventional CC.

A propeller related vehicle in accordance with one embodiment of the present invention is described as a helicopter having an airframe housing a motor mechanism for powering a main propeller attached to a main drive shaft that extends vertically through the airframe and for powering a tail rotor. The helicopter further includes a horizontal stabilizing mechanism attached between the main propeller and the main drive shaft, which permits the main propeller to freely pivot about the main drive shaft independently from the airframe.

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.

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.
