Title: Greg DeMaggio: Innovator in Optical Sensors and Photovoltaic Technology
Introduction
Greg DeMaggio is a notable inventor based in Ann Arbor, Michigan. He has made significant contributions to the fields of optical sensors and photovoltaic technology. With a total of four patents to his name, DeMaggio's work reflects a commitment to advancing technology in innovative ways.
Latest Patents
Among his latest patents is a non-contact optical sensor designed for synchronizing to free rotating sample platens with asymmetry. This invention involves a method and apparatus for determining the synchronicity of a rotary platen in a vacuum deposition chamber. A light source projects a highly collimated light beam onto the rotating platen, tracing a circular swept path that alternates between samples and intervening webs. The samples are significantly more reflective than the webs, and the platen includes an asymmetry feature along the swept path. A detector measures light signals reflected from the platen and generates a unique signal upon encountering the asymmetry feature. A microcontroller then generates a trigger pulse synchronized to this unique signal.
Another significant patent focuses on a higher selectivity method for passivating short circuit current paths in semiconductor devices. This method employs a passivation agent and a counter electrode, controlling the application of current to ensure high selectivity in modifying the transparent conductive oxide material of a photovoltaic module adjacent to short circuit defects, while leaving non-defect areas unmodified.
