Title: Ioan T Oltean: Innovator in Eye Tracking and Digital Pulse Width Modulation
Introduction
Ioan T Oltean is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the fields of eye tracking technology and digital pulse width modulation. With a total of 2 patents, his work has advanced the capabilities of medical devices and electronic circuits.
Latest Patents
One of Oltean's latest patents is an eye tracking device for laser eye surgery using corneal margin detection. This innovative system derives relative eye position by tracking a boundary such as the limbus. Light can be scanned along the limbus, and the measured intensity of reflected light is processed to derive the eye's position. Another significant patent is for a digital pulse width modulator. This circuit and method include a first pulse width clock signal modulated by a second pulse width clock signal that represents a converted analog voltage input. The first and second pulse width signals are provided to a counter that counts to a predetermined gate count, resulting in an output pulse width signal that is proportional to the analog voltage input.
Career Highlights
Oltean is currently employed at Visx, Inc., where he continues to develop innovative technologies. His work has been instrumental in enhancing the precision and effectiveness of laser eye surgery.
Collaborations
Throughout his career, Oltean has collaborated with notable colleagues, including John Karl Shimmick and Terrance N Clapham. These partnerships have contributed to the successful development of his patented technologies.
