Title: Innovations of James T. Dewberry

Introduction

James T. Dewberry is an accomplished inventor based in Moore, SC (US). He has made significant contributions to the field of braking systems, particularly in railcar technology. With a total of two patents to his name, Dewberry's work focuses on enhancing safety and efficiency in braking mechanisms.

Latest Patents

Dewberry's latest patents include a software-based brake shoe wear determination system. This innovative technology calculates the energy used by friction brake equipment to monitor the wear of brake shoes or pads. As the energy supplied approaches a predetermined percentage of the design limit, the system provides an indication for inspection. If the friction energy continues to increase, it signals that the brake material must be replaced. This invention allows maintenance personnel to customize the software logic for specific configurations. It measures the friction effort supplied over time and distance, enabling the software to determine when the brake material needs replacement based on actual data. This proactive approach helps avoid costly damage from using worn-out brake components.

Another notable patent is the brake effort monitor for railcar braking systems. This device receives a brake effort request signal and a vehicle speed signal to generate an energy requested signal. It also receives an actual energy signal to create a performance comparison signal. The system stores these signals for further analysis, enhancing the overall performance of railcar braking systems.
