Abstract: A remote controlled circuit breaker for battery powered riding toys and method of using is disclosed. The circuit breaker is capable of being installed into standard electrical systems of battery powered riding toys via complementary connectors. If the child encounters danger while riding, the handler of the remote control can push the “Stop” button to switch the circuit breaker, thus preventing electric current flow through the toy. Once danger is averted, the handler of the remote control can push the “Go” button, which switches the circuit breaker to allow current flow from the battery to the motor, and thus allowing movement of the vehicle.

Abstract: Disclosed are an apparatus and method for controlling vehicle brake using the brain waves. A driver controls the brake using the characteristic of the brain waves appearing before the driver's movement in the course of stepping on the brake pedal for braking in a dangerous condition. Therefore, the brake can be operated faster, and a condition where the brake is operated in an unwanted situation is prevented to prevent a traffic accident in advance. Further, the present invention does not require a driver's specific intentional behavior or psychological action except for natural behavior for braking (behavior to step on the brake pedal). Accordingly, the present invention makes a user convenient and is suitable for an ordinary person.

Abstract: The present invention comprises a braking or steering mechanism that is located near the steering pivot point of a runner of a ski vehicle. In a conventional snowmobile, for example, the steering pivot point is near the middle of the longitudinal axis of the runner, and, hence, the preferred braking and steering mechanism extends from near, but not at the rear end of, the runner, to contact the snow or ground to slow or stop the snowmobile movement relative to the snow or ground.
