The invention discloses a kind of toy train comprises a locomotive and a train body; the locomotive is provided with a spray device, a battery for supplying power for the spray device, and a control unit for controlling spray; the spray device comprises a water storage bin, an atomizing generator, three spray ports and a water filling port; the atomizing generator is electrically connected with the control unit; the spray ports are respectively arranged at the top and both sides of the water storage bin; and during use, the spray ports spray toward an upper part and both sides at the same time, with three-dimensional spray effect. The invention breaks the traditional spray device modeling, and improves the arrangement positions of the spray ports to change the spray direction so that the spray is more three-dimensional and the structural form of the toy train that can spray is enriched.

A system and method is provided for monitoring and controlling a load disposed at least partially within a model vehicle. Preferred embodiments of the present invention operate in accordance with a load car that includes a load, a motor, and a controller for operating the motor to raise and lower the load. In one embodiment, the controller is configured to monitor at least one metric (e.g., a coal level) and to operate the motor so that the vertical position of the load (e.g., a coal load) is synchronized to the metric. If the metric goes up, then the load is moved (e.g., via the motor) in an upward direction. Alternatively, if the metric goes down, then the load is moved (e.g., via the motor) in a downward direction.

The present invention discloses a system and method for recognizing objects placed together using capacitance sensors in conjunction with the RFID technology. A structure that is made with a material of high dielectric constant and a RFID tag that comprises a unique identification code (UID) of an object is embedded with the object. With the objects recognized, the spatial structure or the spatial distribution formed by them is derived and corresponding sensory feedbacks are provided by the system.

An interactive toy system is shown and described. The toy system can include a container forming a receptacle and having a top opening and a carriage. The carriage is disposed in the receptacle and rotatable about an axis between a first position and a second position. The carriage has a first receiving space and a second receiving space. The first receiving space is accessible through the top opening when the carriage is in the first position and inaccessible when the carriage is in the second position. The second receiving space is accessible through the top opening when the carriage is in the second position and inaccessible when the carriage is in the first position. The toy system can include a fog system configured to generate fog within the container. The fog obfuscating the first receiving space.
