Title: Innovations by Richard Bamfield in Highway-Rail Crossing Safety
Introduction
Richard Bamfield is an accomplished inventor based in Upland, California. He has made significant contributions to the field of safety systems for highway-rail crossings. With a total of four patents to his name, Bamfield's work focuses on enhancing the safety and efficiency of rail grade crossings.
Latest Patents
Bamfield's latest patents include innovative technologies aimed at providing relatively constant warning time at highway-rail crossings. One of his notable inventions is an apparatus and methods for providing consistent warning time at rail grade crossings. This system utilizes a communication protocol that predicts the approach of a train and generates signals to alert crossing controllers. The first communication signal is activated upon prediction, while a second signal is generated for slower-moving trains, ensuring that warning times remain constant. Additionally, cancellation timers are employed to manage situations where a train does not enter the approach or leaves via a switch.
Another significant patent is the highway-rail grade crossing controller with an out-of-service mode. This electronic controller is designed to activate warning devices when a train is detected in either the approach or island circuits. It features a touch-sensitive display that allows maintainers to take circuits out of service and select the duration for which they remain inactive. Service is automatically restored once the selected time expires.
