Latest Patents

Kainan Cha's latest patents include a "Decentralized Radio Frequency Identification System" and an "Adaptive Inventory Management System." The decentralized RFID system provides a method for adaptively adjusting the power of an RFID reader in a network of readers communicating with an RFID tag. This innovative approach controls the transmission power of each reader based on interference sensed from other readers and the current signal-to-noise ratio (SNR) of the backscatter signal received from the tag. If the current SNR exceeds the required threshold, the transmission power is reduced, minimizing interference for other readers. Conversely, if the expected SNR falls below the required level, the power is increased to ensure the target SNR is achieved.

The adaptive inventory management system addresses frequency interference issues within facilities that utilize multiple RFID readers for tracking and managing inventory. A middleware server activates and deactivates adjacent RFID readers based on the location of an item with an RFID tag. It also queries an inventory database using information collected from the RFID tag and generates command signals to control the travel route of vehicles transporting inventory items within the facility.
