Title: The Innovations of Donald E. Barnett
Introduction
Donald E. Barnett is a notable inventor based in West Chester, PA (US). He has made significant contributions to the field of position measurement technology, holding a total of 3 patents. His work has been instrumental in advancing the capabilities of optical encoders and reference signal generation.
Latest Patents
One of Barnett's latest patents is an "Encoder for providing incremental and absolute position data." This invention features an optical encoder with a single data track that is scanned photoelectrically. The data track consists of an incremental track and multiple overlying code tracks, allowing for the generation of both incremental output signals and coarse absolute positional information. The scanning unit includes a first detecting unit with a phased array of photodetectors for scanning the incremental graduation, and a second detecting unit for scanning the code tracks, which can generate commutation signals for brushless motors.
Another significant patent is the "Method for generating a synthetic reference signal for comparison with scanning signals." This method and device generate a reference signal using the same components that scan a scale. By averaging the scanning signals, the reference signal is always less than the higher state of any scanning signal, ensuring accuracy in position measurement.
