Latest Patents

One of Roger Tong's latest patents is for a "Transceiver redundancy in an electronic toll collection system." This invention features a reader that includes a switching network and multiple transceivers controlled by a central controller. The system is equipped with failure detection circuitry that identifies any transceiver failures based on their RF outputs. If a failure is detected, the controller adjusts the switching pattern to exclude the failed transceiver, ensuring continuous operation. This design allows for adaptive RF channel assignment, enhancing the system's reliability.

Another notable patent is the "Dual mode electronic toll collection transponder." This transponder is designed for RF communications with roadside readers from vehicles. It comprises an antenna, an electronic toll collection (ETC) component, and an external interface. The ETC component follows a predefined communications protocol to interpret received signals and generate responses in ETC mode. Additionally, it features a bypass port that allows the transponder to enter a bypass mode, transmitting input signals directly to the reader without implementing the ETC protocol.
