Title: The Innovations of Daniel Catalan
Introduction
Daniel Catalan is an accomplished inventor based in San Jose, CA. He has made significant contributions to the field of technology, holding a total of 3 patents. His work primarily focuses on advancements in physical vapor deposition systems and stepper motor technology.
Latest Patents
One of Catalan's latest patents is titled "Retuning for Impedance Matching Network Control." This invention involves a physical vapor deposition system that includes an RF generator. The RF generator transmits an AC process signal to a deposition chamber via an RF matching network. The controller of the RF matching network receives DC magnitude and phase error signals, allowing it to vary the impedance in response to these signals. The matching network operates in various modes until it is properly tuned, utilizing a composite value of magnitude and phase error to drive the tuning process.
Another notable patent is the "Method for Repeatable Stepper Motor Homing." This method enhances the homing process of a stepping motor by applying a first drive current to rotate the rotor away from an end-of-travel position. After detecting the end-of-travel position, the rotor is rotated back toward it, and the drive current is adjusted to ensure precise positioning. This innovation improves the reliability and accuracy of stepper motors in various applications.
