An intelligent plush toy having a hand-warming function comprises a toy main body. The toy main body comprises a heat storage member, a layered outer casing, an electric heating electrode, and a heating electrode connector. A box is provided inside a plush layer of the plush toy. An upper surface of the box is an electronic ink screen. An image of a character in a certain situation is provided inside the box. The electronic ink screen is connected to a speed-change moving device and a motor inside the box. The box is further provided therein with an audio player for playing nursery rhymes and music for children. The speed-change moving device, the motor and the audio player are in communication connection with a microcontroller inside the box. The electronic ink screen, the speed-change moving device, the motor, the microcontroller and the audio player are all connected to a battery inside the box. The toy can be used to warm hands and enables a child to learn pronunciation and recognition of characters. When the box generates a sound, a motion of a character is presented on the electronic ink screen by means of the speed-change moving device and the motor, thereby facilitating learning of a child.
A: The present disclosure relates to a transfer bin, transfer system, and information display control method thereof. The transfer bin comprises: a bin body; an electronic ink screen, said electronic ink screen being arranged on the outer surface of the bin body; a wireless communication module, said wireless communication module being arranged on the bin body; a processor, said processor being separately connected to the electronic ink screen and the wireless communication module; a power supply module, said power supply module being used for supplying power to the electronic ink screen, the wireless communication module, and the processor; when the transfer bin is located in a preset area, the wireless communication module receives a first signal, the wireless communication module sends a wake-up signal and a second signal to the processor, the processor is awakened and wakes the wireless communication module on the basis of the second signal, and controls the electronic ink screen to update display information and then power off the electronic ink screen, whereafter the processor enters a sleep state.
B: An electronic ink screen and a manufacturing method therefor. The electronic ink screen comprises a display module (1), a control module (2) and a circuit module (3), wherein the display module (1) comprises a plurality of pixel units, and is configured to perform display by using electronic ink; the control module (2) is configured to convert, by means of an electrode micro-structure, a touch-control signal applied from the outside into an electrical signal change of a corresponding pixel unit, such that the display state of the pixel unit changes from an initial state; the electrode micro-structure comprises sub-electrode micro-structures (4) corresponding to pixel units on a one-to-one basis; and each sub-electrode micro-structure (4) comprises a first nano-electrode (41) and a second nano-electrode (42) which are made of different materials, with the two being arranged to be spaced apart from each other and being configured to be in frictional contact with each other when receiving the touch-control signal applied from the outside, so as to cause charge transfer. The electronic ink screen can prevent a display delay; moreover, energy is consumed only when electronic ink is deflected, without requiring additional power consumption, such that the energy consumption thereof can be effectively reduced.
C: A plush toy has an outer section (1) sewn from a plush fabric and an inner section (2) to be inflated with air. A liquid-filled separate sub-section (3) is arranged at a bottom portion of the inner section (2) for providing the plush toy with a stable center of gravity. The inner section (2) is provided with an inflation nozzle (4). The plush toy can be deflated to a small size for convenient storage and transport. After being inflated, the plush toy can stand due to a lower center of gravity, and is equivalent to a roly-poly toy. A child can use the plush toy to practice boxing and wrestling and train. Since the plush toy has a soft texture and is light, it does not cause damage to the skin and bones of the child.
D: An electronic signage, an electronic signage system and a method for controlling the same. The electronic signage comprises an electronic ink screen (2), a wireless transmission circuit (3), a near field communication circuit (4) and a microcontroller (1). The microcontroller (1) is respectively connected to the electronic ink screen (2), the wireless transmission circuit (3) and the near field communication circuit (4). The microcontroller (1) is used to read user information by means of the near field communication circuit (4), to send the user information and receive input information by means of the wireless transmission circuit (3), to control the electronic ink screen (2) to display the input information, and to deenergize the electronic ink screen (2) after the electronic ink screen (2) has displayed the input information.
