Abstract: A skate pole device can be used alone or in pairs by a roller skater in order to advance or retard movement along a skate surface. The skate pole has an elongated shaft with a handle portion on one end and a foot portion on the other end. First and second pads are mounted in the foot portion. The first pad is constructed of a type adapted to frictionally grip the skate surface so that the skater may exert a thrusting motion with the skate pole, and this material may be a stiff, yet resilient, rubber-like substance such as a soft thermoplastic. The second pad is constructed of a different type of material, such as a hard thermoplastic, that is adapted to act as a brake pad against the skate surface so that the skater may apply a drag force. A pair of such skate poles may be used and, if desired, interconnecting elements are provided to releasably secure two such skate poles alongside one another.

Abstract: A brake for roller skates comprising a simple, lightweight mechanism which multiplies the force exerted by the skater into a substantial braking force. The force is exerted by the skater by pushing downward with the heel, which rotates the boot with respect to the frame of the skate. That force is transmitted with leverage to braking shoes or pads that impinge on brake drums adjacent to the wheels. Adjustment for brake wear is provided by a screw that compensates for the shortening of the brake shoe as normal wear occurs. A detent mechanism locks the boot and frame together during normal skating.

Abstract: An automotive suspension control system for anti-rolling motion control is provided. This system serves to adjust wheel loads acting on driven wheels when a wheel speed difference between the driven wheels is greater than a preselected value, concluding that slippage occurs at one of the driven wheels, the adjustment is carried out for securing traction of a slipping driven wheel. The system is responsive to lateral acceleration acting on a vehicle body to decrease a degree of adjustment of the wheel loads according to increase in the lateral acceleration for enhancing cornering stability on road surfaces having different friction coefficients.
Abstract: A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.
Abstract: Several embodiments of electric power assisted bicycles wherein an electrical motor is employed for assisting in the pedaling of the bicycle. The embodiments all include an arrangement for changing the state of the electrical power in response to pushing of the bicycle. In some embodiments, the circuit for the electric motor is opened when the bicycle is pushed rearwardly so as to avoid undue resistance to the pushing as might occur due to the fact that the motor would operate as a generator under this condition and provide an electrical load. In other embodiments, the electric motor is energized upon pushing so as to assist in pushing the bicycle.
Abstract: A binding for a cross-country ski shoe in which the shoe is mounted for pivotal movement about an axis transverse to the longitudinal axis of the ski. An elastic bumper exerts a return force on the shoe when the shoe is lifted from the upper surface of the ski. The elastic bumper is brought into a prestressed condition during the closing of the binding. The prestressing is achieved by either the displacement of the shoe with respect to the elastic bumper or displacement of the elastic bumper with respect to the shoe. This displacement may either be slidable or pivotal movement of a carriage.
