A non-pneumatic tire for supporting a load by working in tension comprising a generally annular inner surface, a generally annular outer ring, and an interconnected web having a plurality of web elements and comprising a plurality of generally polygonal openings. Web elements are sized, oriented and comprised of a material that facilitates buckling when subjected to a compressive load. By buckling, those elements in a deformed portion of the tire between a hub and a footprint region where the tire contacts a surface may assume a significantly reduced portion of the load, if any. This causes web elements in other portions of the interconnected web to operate in tension to support the load. Since the tire is non-pneumatic, it may be easier to maintain and may have a longer life than standard pneumatic tires since it eliminates the possibility of blowouts, flat tires, or tires operating with low air pressure. By virtue of the portion of the tire in the footprint region not bearing a significant portion of the load, non-pneumatic tire may also exhibit a more comfortable ride subject to less noise and vibration and improved handling capabilities.

A control apparatus for a multi-phase rotary machine includes a control unit and a plurality of power supply systems including respective inverter units. When a short-circuiting failure occurs in one of the systems due to an ON-failure in any one of FETs in an inverter unit of the failure system, the control unit stops driving of the rotary machine by bringing all the FETs in the failure system into the OFF state. The control unit controls FETs of the non-failure system such that a brake torque generated in the failure system is cancelled or the influence of the brake torque exerted on the driving of the motor is reduced.

A pneumatic pogo stick is comprised of an elongate cylindrical housing which forms a cylinder. The housing is formed from a clear polycarbonate plastic. A top cap is attached to one end of the housing to form the top of an air chamber. A plastic piston, slidable within the cylinder, forms the bottom of the air chamber. An elongate shaft is coupled to the bottom of the piston and is moveable therewith, extending from the distal end of said housing as the piston moves within the cylinder. A bottom bracket assembly is attached to the bottom of the housing and a bushing for maintaining the lateral position of the shaft relative to the housing is attached to the bottom bracket assembly. The bushing prevents the shaft from rotating relative to the housing. User foot supports are also attached to the bottom bracket for supporting the feet of the user and handle bars are attached to the top cap for grasping with the hands of a user.

A watercraft seat suspension includes a damper mounted between a watercraft seat and the watercraft hull. The damper includes an electrically actuated mechanism controlling fluid flow from a first chamber to a second chamber within the damper. A sensor senses motion of the seat relative to the hull. A control unit interpolates the sensor signal and develops an actuating signal controlling the electrically actuated mechanism. In one arrangement, the electrically actuated mechanism is a solenoid actuated by the actuating signal to effect one of two different damping modes. In another arrangement, the electrically actuated mechanism includes a conductor coil and flux ring generating a magnetic field proportional to the actuating signal to vary the viscosity of magneto-rheological fluid in the damper.
