Introduction

Qiushu Chen is a prominent inventor based in San Jose, California, known for his significant contributions to the field of additive manufacturing. With a total of 15 patents to his name, Chen has developed innovative technologies that enhance the capabilities of 3D printing.

Latest Patents

One of his latest patents is the "Real-time molten droplet analyzer with spatial modulation in additive manufacturing." This invention discloses techniques for determining characteristics of a stream of jetted material in a 3D printer. The system includes an ejector that releases molten droplets along a jetting path to a build platform. A sensor positioned adjacent to the jetting path generates an electrical signal in response to light from the molten droplets. An optical mask modulates this electrical signal as the droplets travel, while processing devices analyze the signal to identify characteristics of the droplets and control the 3D printer accordingly.

Another notable patent is the "System and method for processing signals acquired from multiplexed optical sensors." This method involves receiving streaming data from multiplexed optical sensors of optical fibers. It determines whether the number of peak readings matches an expected number and corrects any anomalies in the data. The method also stores both nominal and corrected data in a structured table indexed by fiber and sensor ID.
