  • Patent number: 10512852
    Abstract: A track for a toy vehicle includes several track units. Each track unit has an upper layer and a spaced apart lower layer. Each of the adjacent units comprises two sections. A first section has an upper side for supporting the toy vehicle and a bottom side. A second section has an upper layer having a top side for supporting the toy vehicle and a lower base. The first section has a first connector, and the second section has a mating second connector. The first and second connectors are connectable so that first and second sections are connectable in an adjacent unit to form an adjacency relationship. Each unit includes a first section and two second sections. Two second sections are located at opposite longitudinal ends of the first section. The first section is bendable in a longitudinal sense substantially parallel to a plane on which a track is directed from one end to the other end in a track running direction.

  • Patent number: 9878261
    Abstract: A toy flowerpot with a movable toy flower includes a battery to power a mechanism in the toy flower. The flower includes the parts of a stem, sepal, petals and a front flower face around which the petals are mounted, at least one of which parts is a reactive part. A mechanism moves one or more parts of the flower; and includes an actuator with a magnet and electromagnetic coil with the flower. A signal receiver or sensor of changes causes at least one of movement of the flower parts. A microprocessor processes the signal or sensed change and generates instructions to change the operation of the electromagnetic coil in response to the signal or sensed change.

  • Patent number: 9108115
    Abstract: An interactive toy has an outer shell, with a non-reactive portion and a first reactive portion. There is a blow sensor for sensing blowing on the shell by a user or from sound from the user or another toy. A microprocessor processes the blowing or sound and generates instructions to cause operation of the reactive portion of the body. Several toys can be responsive to at least one of the toys or sounds, the responsiveness being generated from the user or from other of the several toys to obtain a multiple reaction of multiple toys as a started from an initial blowing or sound by a user or by a sound generation by of the multiple toys.
