Latest Patents

Jie Sun holds a patent for a "System for obtaining vehicular traffic flow data from a tire pressure monitoring system." This invention utilizes an embedded Tire Pressure Monitoring System (TPMS) sensor integrated into vehicular wheels. The system employs a secured central server to track the unique identification codes of each sensor. The TPMS is installed by manufacturers in compliance with the federally mandated TREAD Act of 2000. When a vehicle comes within the detection radius of an encrypted TPM sensor, its identification codes are recorded and time-stamped. If the vehicle subsequently enters the area of a second encrypted TPM sensor, the codes are recorded again, encrypted, and sent to the secured central server. This process allows the server to calculate accurate traffic flow data based on the two encrypted, time-stamped signals.
