摘要： A toy includes a vehicle body having a front portion and a rear portion. A pair of rear wheels is coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion. A first electric motor is drivingly coupled with the at least one rear wheel. There is a pair of front wheels coupled with the front portion and located on the vehicle so as to at least partially support the front portion. The wheels have two sets of 3-dimensional spokes act as a level of shock absorbent freedom of rotation and a freedom of translation thereby to absorb kinetic energy from an impact force.

摘要： A sound generating device comprises top, bottom and sound generating assemblies. The sound generating assembly comprises a microprocessor, sound chip, capacitor, speaker and power source that are electrically interconnected. The sound can range from animal and/or environmental sounds, music, congratulatory messages, other types of voice recordings, bells, whistles and the like, and the length of play can be varied. When the device is struck against a hard surface, the contact in the top is depressed and interacts with a receptor on the sound generating device to communicate with the microprocessor and sound chip to generate a sound, which can persist from about one or more seconds, depending on how the sound generating device had been programmed. Repeat strikes of the sound generating device against the surface will result in a repetition of the sound.

摘要： A propulsion system for an aerial vehicle or toy aerial vehicle includes a bladeless fan drive and a peripheral ground-engagement part. The bladeless fan drive operates in a plane (x′-y′) and is configured for producing thrust. The peripheral ground-engagement part comprises a hubless wheel and a rotatable tire component. The bladeless fan drive is secured within the hubless wheel by two pivot points on opposing sides of the bladeless fan drive, such that the plane of the bladeless fan drive is pivotable about a pivot axis (x′) spanning between the two pivot points, the pivot axis (x′) being orthogonal to a hubless wheel axis (z) of the peripheral ground-engagement part.

摘要： Specific classroom tools, toys, and vehicles including a connected plastic and non-conductive materials including encasements around front and back positioned same polarity magnets only and electromagnets train car including train cars with and without energy sources for the purpose of providing invisible contact repulsion between cars and vehicle movement when force is applied to the first car. The invention includes attaching magnetic and electromagnet encasements to the front and back of train cars. The encasements allow close and distant magnet and electromagnet impactful interactions between cars with and without bottom-positioned wheels. The invention is usable for classrooms, toys, and as vehicles and provides a permanently-attached-to-train car thick plastic fence-net-type encasements around magnets providing reduced contact potential and possible magnet-to-magnet contact and desired magnet type, size, power, and only one polarity one-side magnets to reduce magnet attraction and hence provides safety and protection for younger users.
