Title: Innovations of Robert H. Hearn: A Pioneer in Adaptive Detection Technology
Introduction
Robert H. Hearn, based in San Diego, California, is a distinguished inventor known for his contributions to adaptive detection technologies. With a total of two patents to his name, Hearn's advancements have important implications for signal processing and analysis.
Latest Patents
Hearn's latest patents include the "Adaptive Detector" and the "Adaptive Line Enhancer." The adaptive detector consists of an adaptive linear prediction filter (ALPF) and a detection processor. It features an input filter that receives an input signal and processes it through various stages, ultimately delivering an error signal that optimizes detection sensitivity. The detection processor performs a K-point discrete Fourier transform (DFT) on the output signal, facilitating comprehensive spectral analysis.
In the adaptive line enhancer, an input signal is combined with a delayed version of itself and processed through an adaptive linear transversal filter. The output, which is the difference between the two signals, creates an error signal that is minimized through a recursive algorithm. This innovative design stabilizes the filter by readjusting the weights until the mean square error is minimized, enhancing signal clarity in various applications.
