Abstract: A method and system for wireless communication are disclosed. The method comprises: the master device generates a sequence code through a specific encoder and transmits the sequence code to each slave device continuously within a preset period according to the communication demand, wherein the specific encoder is a feedback shift register constructed by a specific polynomial, of which the coefficients and the order are in correlation with the communication demand while all of the coefficients and initial values are not equal to 0 at the same time; the preset period is greater than or equal to the sum of a sleeping period and a detecting period of the slave device, which constitutes a sleeping-and-waking cycle; the slave device receives a continuous section of the sequence code in the detecting period, decodes the sequence code through a decoder corresponding to the encoder, and performs corresponding operation according to the decoding result.

Abstract: A squeezable tongue-wagging toy figure with a squeeze mechanism which includes a squeaker provided within a space defined by four hinged panels in elliptical cylinder shape, and a toothed rack meshed with a gear chain that is coupled with a bar with a toy tongue. When the panels are squeezed, the rack drives the gear chain in one direction and in turn pivot the bar towards one side and the squeaker produces a sound, and when the panels are released, the rack drives the gear chain in an opposite direction and in turn pivot the bar towards an opposite side and the squeaker produces another sound.

Abstract: A squeezable face-covering toy includes a toy figure having a face, left and right arms and a squeeze mechanism mounted inside the toy figure. The squeeze mechanism includes four curved panels connected end-to-end by four hinges, and left and right arm supports configured to support the left and right arms respectively. A spring is fastened between two opposite hinges whereby squeezing the squeeze mechanism moves the arms from an initial face-covering position to a face-revealing position.

Abstract: A bubble generating toy includes a bubble forming assembly mounted inside a housing behind a front opening thereof. The bubble forming assembly includes a cylindrical body having diametric inlet and outlet, a cylindrical air gate having diametric inlet and outlet. The air gate is rotatable in the cylindrical body between a closed position and open position when the inlets and outlets are aligned. A sleeve extends perpendicularly from the outlet of the cylindrical body and has a bubble ring. Bubble forming liquid is pumped from a container, through a tube and into the sleeve by a pump to form a bubble film across the bubble ring. An air blower blows are through the sleeve and the bubble ring to generate bubbles.
