Abstract: A toy racetrack having an obstacle that is moved into and out of the path of a toy vehicle travelling along the racetrack is provided. The racetrack includes a closed loop track and may include a booster mechanism for propelling a toy vehicle along the track. The obstacle may be formed by a movable web or net with an opening that can be used to catch a toy vehicle traveling along the track. A support tower is located adjacent the track, and an obstacle carrier, optionally including an action figure, is movably mounted to the support tower. The figure holds the net, and the figure and net are movable between a raised position and a lowered position. When the net is in its lowered position, a toy vehicle traveling along the track is captured by the net when the net is manually positioned in a capture position.

Abstract: The present invention discloses a method for transmitting parallelization signals of uninterruptible power supplies, which firstly performs a serialization process on parallelization signals by a logic processing unit and then performs synchronous transmission of the parallelization signals of respective node units over a bus. The method for serial transmission of parallelization signals of uninterruptible power supplies according to the invention can be implemented with easy wiring and can achieve a strong anti-interference ability, ensure real time signal transmission over a guaranteed transmission distance and identify conveniently the failure of a parallelization line while satisfying fundamental transmission demands.
