Abstract: A child's riding vehicle such as a tricycle has a secondary steering column through which the parent walking behind the tricycle may steer the tricycle. The secondary steering column is coupled to the first steering column by a pair of rods that are attached at their respective ends to a first flange around the primary steering column and a second flange around the secondary steering column. The steering rods also act as steering limiters by contacting the wheel fork tube at a predetermined maximum steering angle and resisting further rotation of the flange. The mechanism lies entirely within the hollow frame of the tricycle for safety. The child's steering handle can be disengaged from the fork tube to allow the parent to completely control the steering without interference from the child.

Abstract: A universal tactile feedback system for computer and video game systems is disclosed which provides real time tactile feedback to enhance a user's experience while interacting with a computer/video game or simulation. The tactile feedback system operates both in host-independent and host-dependent modes, thereby allowing the system to function even when no accommodation is provided by the game or simulation system that is being used. The host-independent mode is responsive to the audio signal that is typically generated by a computer or video game system while it is executing a game or simulation. The host-dependent mode is responsive to control commands specifically generated by a computer or video game system while it is executing a game or simulation. The tactile feedback system then creates tactile sensations primarily via controller-based tactile sensation generators, such that the user feels physical sensations corresponding to events occurring within the game or simulation in real time.

Therefore, laser beams can be applied continuously and efficiently without energy deterioration.

Abstract: When semi-amorphous TFTs are used for forming a signal line driver circuit and a pixel, a large amplitude is required for driving the pixel, and a large power supply voltage is thus needed. On the other hand, when a shift register is made up of transistors having a single conductivity, a bootstrap circuit is required, and a voltage over a power supply is applied to a specific element. Therefore, not both the driving amplitude and the reliability can be achieved with a single power supply. According to the invention, a level shifter having a single conductivity is provided to solve such a problem.
