Abstract: A rotary flying ball includes a main housing, a bracket, a paddle, a main control board, a power supply, a motor, and a lamp strip; the housing is spherical with an accommodation space therein and multiple holes thereon, the multiple holes are communicated with the accommodation space. The bracket is mounted in the accommodation space, the bracket provides a shaft, a center of the shaft coincides with a center of the main housing. The paddle is located in the accommodating space and rotatably disposed on the shaft; the main control board, the power supply, the motor, and the lamp strip are mounted on the bracket; the power supply, the motor, and the lamp strip are electrically connected to the main control board, the motor drives the paddle to rotate.

Abstract: The present invention relates to the field of rotary imaging, in particular to a rotary imaging system, a rotary imaging method and a rotary device. A rotary imaging system of a rotary device comprises a rotating body with a lamp belt module group; a circuit board installed on the rotating body, the circuit board rotating synchronously with the rotating body; an acceleration detection component installed at a predetermined position on the circuit board for acquiring acceleration detection data at the predetermined position when the circuit board rotates; and a control module used for obtaining an acceleration value of the predetermined position based on the acceleration detection data, further obtaining a rotation speed value of the circuit board based on the acceleration value and a position parameter corresponding to the predetermined position, and driving the lamp belt module group to realize rotary imaging based on the rotation speed value.

Abstract: The present invention discloses a boomerang, which comprises a flight component, a central shaft and a protective device, wherein the flight component comprises at least one rotating device and a driving device; The center of the shaft runs through the center axis of the maximum diameter plane formed when the rotating device rotates, and the protective device is composed of a plurality of ribs connected with each other and arranged around the flight component. The boomerang is safer in use, better in flying performance, more ornamental and playable.

Abstract: A smart interactive toy comprises a shell, an interactive control module, a moving mechanism, and an anti-fall sensing module comprising a first signal sending unit and a signal receiving unit; the first signal sending unit is mounted on the shell, connected electrically with the interactive control module and used for sending a first sensing signal to the interactive control module when the signal receiving unit does not receives a first reflected signal, reflected after the first sensing signal meets an obstacle, in a predetermined time period, so that the interactive control module drives the moving mechanism to stop moving, thereby achieving that the user controls the smart interactive toy to avoid it from falling down a table or into a deep pit, which ensures that the toy can be interacted and is not easy to damage.
