Title: Innovations by Chih-ming James Chiang
Introduction
Chih-ming James Chiang is a notable inventor based in Chandler, AZ (US). He has made significant contributions to the field of medical technology, particularly in the development of advanced pacemaker systems. With a total of five patents to his name, Chiang's work focuses on enhancing the functionality and responsiveness of implantable devices.
Latest Patents
Chiang's latest patents include a "Rate Responsive Pacemaker with Exercise Recovery Using Minute Volume." This innovative device generates a metabolic demand parameter that is converted into a corresponding metabolic indicated parameter. The system determines various characteristics related to exercise, such as duration and intensity, to dynamically calculate an exercise recovery period. This period allows the pacing rate to be elevated above the rate indicated by the metabolic parameter, utilizing fuzzy logic circuitry for optimal performance.
Another significant patent is the "Rate-Responsive Pacemaker with Noise-Rejecting Minute Volume." This device also generates a metabolic demand parameter, such as thoracic impedance, which is converted into a metabolic indicated parameter. During this conversion, intermediate parameters are used by a cross-check circuit to eliminate artifacts caused by noise, ensuring accurate readings. The peak limiter is employed to maintain the metabolic indicated rate within an acceptable range, again utilizing fuzzy logic components for enhanced reliability.
Career Highlights
Chiang is currently employed at Pacesetter, Inc., where he continues to innovate in the field of cardiac devices. His work has contributed to advancements in patient care and the effectiveness of pacemaker technology.
