Abstract: A system includes a mobile unit, road and procedure pieces, and a controller on the mobile unit that includes an optical sensor, a storage storing instructions and identification lookup tables, and a processor connected to the optical sensor and the storage. The optical sensor scans recognition patterns on the procedure pieces and identification patterns on the road pieces to correspondingly obtain recognition and identification codes. The processor controls the mobile unit to perform actions based on a collection of instructions generated according to the recognition codes and the instruction lookup table and based on entries of coordinate information obtained according to the identification codes and the identification lookup table.

Abstract: A flying toy includes a left sector gear, a left wing connector extending radially from the left sector gear, a right sector gear, a right wing connector extending radially from the right sector gear, a drive shaft, a crank piece mounted on the drive shaft to rotate therewith, a crank arm coupled between the crank piece and one of the left and right sector gears, two wing members connected respectively to the left and right wing connectors, and a drive unit configured to drive the drive shaft. The right sector gear is configured to mesh with the left sector gear so as to synchronize up-and-down movement of the left and right wing connectors to thereby result in a flapping motion of the two wing members.

Abstract: A wall climbing toy includes a frame body, a drive shaft, a plurality of spring-loaded release valves, a cam shaft, a drive unit, a left gear train, a shaft extension, a plurality of primary crank arms, a plurality of connecting rods, a plurality of suction cups, and a plurality of air tube units. When each of the spring-loaded release valves is displaced from a seal position to an open position, an air seal formed between a corresponding one of the suction cups and a flat surface is broken. When the drive shaft is driven concurrently with the cam shaft to rotate, the air seals formed between the suction cups and the flat surface are broken alternately so as to permit the connecting rods to be alternately pulled away from a flat surface.

Abstract: A snap-fit connector includes a female component and a male component. The female component has a retaining hole and two through bores communicating spatially with the retaining hole. The male component has two spaced-apart hooks inserted into the retaining hole. Each of the hooks has a resilient arm, and a protrusion retained in a respective one of the through bores. The protrusion of each of the hooks has an abutment surface abutting against the female component, and a positioning recess formed in a guide surface thereof and accessible via the respective one of the through bores.

Abstract: A traveling toy includes a gyroscopic unit, a traveling unit and an ornamental toy unit. The gyroscopic unit includes a motor having co-rotatable upper and lower output shafts, a rigid body having a rotational symmetry, and mounted co-rotatably on the upper output shaft of the motor, a driving gear mounted co-rotatably on the lower output shaft, and a transmission gear meshing the driving gear. The traveling unit is disposed below the gyroscopic unit, and includes a first bottom wheel adapted for traveling on a surface, and a gear train disposed between and meshing the transmission gear and the first bottom wheel. The ornamental toy unit is provided on the gyroscopic unit.

Abstract: The real-time touchless interaction method of the present invention comprises the following steps: characteristic information of an object is acquired; the characteristic information is recognized and used to generate a 3D icon which corresponds to the object; the characteristic information of the object continues to be acquired, and the 3D icon is reconstructed in real-time based on how the object is manipulated; at the same time, the 3D icon is utilized as an pointer to interact with the smart device without requiring any physical manipulation with the touch screen. A system and a computer program product for real-time touchless interaction are disclosed herein. The present invention enables users to interact with a smart device without physically touching the screen, thereby generating a plethora of new interactive applications and greatly increasing the versatility of available operations between the user and the smart device.
