Latest Patents

Wu is credited with 1 patent: “System and Method for Detecting People Entering and Leaving Field.” The invention uses a receiver positioned above an entrance to collect measurement signals from a transmitter carried by a person. It derives signal strength indication (RSSI) and phase information from those signals, then uses the phase information to calculate the transmitter’s arrival angle. A main console combines the RSSI and arrival angle to estimate the person’s position and analyzes positions over a time interval to determine whether the person passed through the entrance.
