Interactive talking toy

摘要

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.

主权项

1. An interactive talking toy comprising a plurality of toy units, each toy unit comprising:
a transmitter configured to transmit a signal to the other toy units; a receiver configured to receive a signal from the other toy units; a speaker configured to output a voice; and a controller IC being connected with the transmitter, the receiver, and the speaker, and configured to set a plurality of modes for the toy unit based on the communication between the toy unit and the other toy units, and selectively control the speaker to output prerecorded phrases in a predetermined sequence along with the other toy units according to the mode being set for the toy unit and for the other toy units respectively; wherein: the controller IC is configured to check the mode being set for the other toy units at the end of each phrase, and to control the speaker to proceed with outputting the prerecorded phrases in the predetermined sequence along with toy units that are set in a predetermined mode.
