Dr. Martens specializes in control systems and software, microprocessor-based and computer systems, circuit design and analysis, electronic components failure analysis, automotive control systems, electronic stability control systems, programmable logic controllers (PLCs) and process control (including DCS and SCADA analysis), robotics and automation, computer vision, consumer products design and failure analysis, and intellectual property issues. As a member of Delphi’s Innovation Center, Dr. Martens helped maintain the patent portfolio by actively contributing, evaluating competitors’ patents, and supporting infringement claims responses. He has assisted in several intellectual property cases and performed the following services: infringement assessment, examination and testing, claim interpretation, and prior art research. Prior to joining Exponent, Dr. Martens managed the embedded control systems group at Delphi Corporation and led an R & D team from development to commercialization of an active rear steering system for improved vehicle performance. Dr. Martens has experience developing and testing electronic stability control systems. Dr. Martens’ robotic experience includes developing methods and algorithms for the automatic control of a stair-climbing mobile robot. He has experience programming PLCs and analyzing process control systems. Dr. Martens’ facilities management experience at Delphi includes equipment specification, procurement, installation, and maintenance. His facilities experience also includes the maintenance of a mechatronics research and development laboratory containing several industrial robots and control systems.
