Data Reader Using RFID Tag(DEAL 414)

This lot is generally related to various technologies such as a data reader using RFID tag, an automatic answering and a speech recognition system. Disclosed is a data reader for reading data irrespective of position of a radio tag. The data reader has a storage unit for storing data and an antenna for transmitting stored data. The storage unit has a reader and a writer for generating a modulated signal using a carrier wave and multiple antenna units for transmitting radio waves for a read by radiating the modulated signal into the air. The reader/writer has a phase adjustment circuit for changing the phase of a carrier wave. Few patents in the portfolio disclose an automatic answering system which allows conversation to happen based on a course of a conversation which is prepared in advance. The system recognises an utterances from a user and uses a conversation editing device for allowing a novice to generate and edit the conversation. A set of patents disclose a speech recognition system having a speech recognizing unit for receiving a speech signal from a user and outputting characters string related to the speech signal. The technology may be implemented in data reader and positioning system, RFID tag reader, etc.
