Abstract: A apparatus or system defined by a handheld exercise device that includes a weighted body; a handle arranged along a radial axis of the weighted body; and a connector that creates at least one connection between each radially distal end of the handle and a component of the weighted body. The handheld exercise device, in use, minimizes one or more peak forces and rotational inertia acting on a forearm of a user actively engaging the handheld exercise device in motion.

Abstract: A game controlling apparatus designed for using a pedaling (or winding) motion to control a video game. The game controlling apparatus preferably includes a platform element adapted to secure a game controller and at least a first handle and a second handle, each handle being capable of rotation about an axis of rotation relative to the platform element. The game controlling apparatus additionally may include an attachment mechanism adapted to secure the game controller to the platform. The first and second handle are preferably positioned on opposite sides of the platform element and on opposite ends of the platform element so that a pedaling motion while gripping the first and second handle will produce rotation of the game controller preferably about a centrally located point on the game controller.

Abstract: The gyroscopic device of the preferred embodiments includes a housing; a gyroscope within the housing; and a first handle having a first joint, wherein the first joint is coupled to the housing and is located such that when a user grasps the first handle, the first joint is located along the center line of the user's palm and adjacent to the user's wrist. The gyroscope preferably includes a track defining a continuous surface with a circular shape, a rotor that spins about a spin axis and rotates about a rotational axis, wherein the rotor has axle tips that frictionally contact the continuous surface of the track, and wherein the frictional contact defines a relationship between a spin rate of the rotor about the spin axis and a rotation rate of the rotor about the rotational axis.

Abstract: A precessional device having independent control of the output torque generated by the device and the oscillation rate of the device is disclosed. The device comprises a rotor supported by an axle wherein the ends of the axle are supported by a circular race. The circular race is rotatable, and may be driven by a motor or other means, thereby controlling the oscillation rate of the device independently of the output torque arising from the rotation rate of the rotor. The motor may be controlled by a control program that adjusts the rotation rate of the circular race to modify the shape of the resistance curve.
