Title: The Innovative Mind of James R. Hume

Introduction

James R. Hume is an accomplished inventor based in Rolling Hills Estate, California. He is known for his significant contributions to traffic signal technology, particularly through his innovative patent that enhances the safety and efficiency of emergency vehicle responses at controlled intersections.

Latest Patents

Hume holds a patent for an "Automatic determination of traffic signal preemption using differential." This system utilizes differential global positioning system (GPS) measurements to accurately monitor the position, speed, and direction of emergency or service vehicles approaching a controlled intersection. The preemption system includes a reference GPS receiver that computes GPS measurement corrections, along with a GPS receiver in each vehicle that transmits its measurements by radio to a receiver located at the intersection. A computer at the intersection uses these corrected measurements to determine the optimal time to switch the traffic light controller to preemption mode, ensuring safe passage for the vehicle.
