ALEXANDRIA, Va., May 5 -- United States Patent no. 12,618,940, issued on May 5, was assigned to Neural Propulsion Systems Inc. (Pleasanton, Calif.).

"Signal detection and denoising systems" was invented by Babak Hassibi (San Marino, Calif.) and Behrooz Rezvani (Petaluma, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Disclosed herein are systems and methods for estimating target ranges, angles of arrival, and speed using optimization procedures. Target ranges are estimated by performing an optimization procedure to obtain a denoised signal, performing a correlation of a transmitted waveform and the denoised signal, and using a result of the correlation to determine an estimate of a distance between th...
