US Patent Issued to Analog Devices on May 19 for "Automatic parameter tuning for active road noise cancellation" (Massachusetts Inventors)

ALEXANDRIA, Va., May 19 -- United States Patent no. 12,633,280, issued on May 19, was assigned to Analog Devices Inc. (Wilmington, Mass.).

"Automatic parameter tuning for active road noise cancellation" was invented by Steven A Wacks (Natick, Mass.) and Alan Christopher O'Connor (Dedham, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for automatic parameter tuning of active road noise cancellation systems are described herein. The system can automatically search for an optimal set of algorithm parameters based on recorded data. An active road noise cancellation algorithm and simulation can be embedded in an auto-differentiation framework, which allows gradients of the algorithm parameters to...
