His work primarily focuses on advanced sensing systems that enhance vehicle safety and performance. His innovative approach and commitment to excellence make him a significant figure in the automotive industry.

Latest Patents

Graf's recent patents reflect his expertise in sensing technology for automotive applications. One of his latest inventions is the "Integrated Silicon Automotive Accelerometer." This single-point impact sensor features a fully differential capacitive sense element, which provides a capacitive difference proportional to vehicle acceleration. The capacitive difference is converted into a digital pulse train signal, modulated for density based on capacitance variations. A hierarchy of counters and timers evaluates the pulse density, determining if the signal indicates an activation-worthy event. Additionally, this invention includes a non-volatile programmable memory to manage the sensor's operation effectively.

Another significant patent by Graf is the "Method and Apparatus for Self-Testing a Single-Point Automotive Impact." This invention focuses on detecting faults in the impact sensing system by employing electrically conductive self-test plates. These plates electrostatically deflect the sense element during a self-test sequence, simulating conditions of an actual activation-worthy impact event. The response time is recorded and compared to a stored expected response in non-volatile memory, which helps identify hard faults or calibration issues in the system. This diagnostic approach ensures the electrical continuity and mechanical integrity of the impact sensing system, providing an essential layer of safety for automotive applications.
