Title: Innovations of Cheng Qi in RFID Technology
Introduction
Cheng Qi is an accomplished inventor based in Atlanta, GA (US). He has made significant contributions to the field of radio frequency identification (RFID) technology. With a total of 4 patents, his work focuses on enhancing the accuracy and efficiency of RFID systems.
Latest Patents
Cheng Qi's latest patents include innovative systems and methods for RFID positioning. One of his patents describes systems and methods for radiolocation using backscatter RFID tags and a special-purpose reader. This reader produces a stepped-frequency continuous wave (SFCW) RF interrogation signal comprising multiple carrier frequencies. The backscattered interrogation signal from the RFID tag is down-converted using a portion of the generated SFCW RF interrogation signal. The received signal phases (RSP) corresponding to the carrier frequencies are determined, and the received signal strength (RSS) may also be calculated to improve performance. This technology allows for estimating the distance between the RFID reader and the backscatter RFID tag based on the summation of differences between RSPs corresponding to adjacent carrier frequencies.
