Abstract: There is provided a projectile, a system and a related method of operation of a projectile comprising: a front ogive section; an aft section; and a control module; wherein the front ogive section is rotatably connected to the aft section by a coupling device, the front ogive section further comprising an asymmetric surface such that the asymmetric surface exerts an imbalance upon the projectile, where in use, the angular rotation of the front ogive section can be selectively adjusted relative to the aft section by commands from the control module to the coupling device influencing a helical trajectory of the projectile in flight thereby causing a change in direction thereby steering the projectile towards a target.

Abstract: An exercise machine including a motor assembly that provides both motor driven resistance forces and motor driven rotation forces. A frame of the machine assists a user in the performance of an exercise, and separates a treadmill portion of the machine from a weightlifting portion of the machine. The treadmill portion is driven by the motor driven rotation forces, and the weightlifting portion is driven by the motor driven resistance forces, thereby providing a universal machine that provides for performance of a plurality of exercises.

Abstract: An exercise apparatus includes a frame, one or more pull cables running through cable guides to provide resistance exercise, and a winding/coiling mechanism for providing variable resistance to the one or more pull cables. A resistance power shaft is engageable with a winding shaft and effective for turning the winding shaft upon rotation of the resistance power shaft. A coupling effective to temporarily disengage the winding/coiling mechanism from a resistance power mechanism, and thus to allow the one or more pull cables to be wound or unwound at a rate different from a rate at which a motor is running may also be included. A cable management spring to bias the one or more pull cables toward a wound condition may be used. A computer/processor may be used to control a resistance force applied to the one or more pull cables and/or to record exercise results.

Abstract: An exercise apparatus includes a frame, one or more pull cables running through cable guides to provide resistance exercise, and a mechanism for providing variable resistance to the cables. The frame may include a pair of uprights and a pair of cross members that combine to form a rectangular construct that allows the cable guides to be mounted at a multiplicity of selected points above and to both sides of a user standing between the uprights. The guides may be mounted at any of the selected points on the uprights and the cross members to allow the user to select an advantageous “pull point” for a desired exercise without moving the frame members and without moving other guides. A computer/processor may be used to control the resistance force applied to the cables and/or to record exercise results.
