Title: Youbok Lee: Innovator in RFID Technology
Introduction
Youbok Lee is a prominent inventor based in Chandler, AZ, known for his contributions to radio-frequency identification (RFID) technology. With a total of 6 patents to his name, Lee has made significant advancements in the field, particularly in the area of anticollision protocols for RFID systems.
Latest Patents
One of Lee's latest patents focuses on an anticollision protocol with fast read requests and additional schemes for reading multiple transponders in an RFID system. This innovation addresses the arbitration of multiple transponders, such as RFID tags, within an interrogation field. The arbitration process is tailored for individual applications and is controlled by the transponder or tag reader. Different wake-up slots are calculated for each tag during successive transmission cycles based on the tag ID and the transmission cycle number. The tag reader can send a special command to a tag to read its data, allowing the tag to become decoupled from the environment. Furthermore, the tags can be placed in either a tag-talk-first mode or a reader-talk-first mode. The protocol also includes a special fast read command that encompasses a read request and various communication control parameters, enhancing the efficiency of transponder communications.
