A skateboard for use on pavement, ice or snow using a single narrow-footprint wheel, ice-blade or ski-runner attached to each foot, thus requiring the rider to dynamically balance the board. The skateboard is capable of self-propulsion at considerable speed on the flat or uphill by using an undulating motion. It can also lean up to 30 degrees and has a steering circle of only two feet. The board's construction comprises a front footboard, a rear footboard, and a strut which connects the two footboards and resists bending and extension. Each footboard includes a footpad, an attachment (i.e. a wheel, blade or ski), and a pivot joint connecting to the strut. The axis of this joint is aligned perpendicular to the footpad which allows the rider to steer each footboard independently by torsionally rotating the lower leg.

A putter golf club that resists twisting by increasing the rotational inertia of the golf club to the maximum degree possible by distributing mass away from the center of mass of the putter, and thereby expands the sweet spot of the putter. Rotational inertia is maximized via use of a heel control wing and a toe control wing extending rearwardly and outwardly from a striking face of the putter as well as a tail rod extending perpendicularly from striking face. Further increase of rotational inertia is accomplished via s symmetrical recesses incorporated into heel and toe control wing.

The isolator may also include an elastomer position between at least a portion of the inner ring and at least a portion of the outer ring to provide enhanced vibration and / or shock isolation during operation of the IMU, and to provide dampening of shock events during bottoming out of isolator during high shock events.

A method and apparatus for operating a pool cleaner body in a manner to maximize the time spent on cleaning relative to the time spent on repositioning. More particularly, the invention is directed to a control subsystem for operating a cleaner body to enable it to primarily travel in a forward direction (i.e., forward state) along a travel path but operable also in a backup / redirect state to translate and or rotate the body to enable it to escape from obstructions while also minimizing the formation of conduit tangles. The control subsystem is configured to perform reposition operations without increasing incidents of conduit tangling by: 1—avoiding an excessive rotation of the body, e.g., approximately 180° or more, when attempting to free the body from an obstruction; and / or 2—avoiding the initiation of a timed reposition operation while the body is transitioning between a travel path at the wall surface and a travel path at the water surface.

A Posterior Dynamic Stabilization (PDS) device that regulates physiologic spinal elongation and compression. Regulation of elongation and compression are critical requirements of Posterior Dynamic Stabilization devices.
