Introduction
Andrew S. Crowe is a notable inventor based in San Jose, CA. He holds 2 patents that showcase his contributions to technology, particularly in the fields of tone detection and signal processing. His work has had a significant impact on communication systems.
Latest Patents
One of Crowe's latest patents is the "Independent hysteresis apparatus for tone detection." This invention is designed to detect tones for call progress monitoring. The apparatus utilizes a counter that monitors the output of a tone detector, incrementing and decrementing based on the presence or absence of a tone. If the counter reaches a predetermined count within a specified time, it indicates that the tone exists. Conversely, if the counter does not reach this threshold, it signifies that the tone does not exist. This technology allows for continuous monitoring of various tones on a common communications channel, even in the presence of noise.
Another significant patent is the "Method for time-scale modification of signals." This method focuses on time-scale modification of signals, such as voice signals. It involves varying the starting positions of blocks in an input signal, known as analysis windows, and reconstructing an output signal by overlapping these windows. The process includes searching for segments of the input signal that are similar to the previous portion of the output signal, using cross-correlation as a similarity measure. This innovative approach enhances the quality of signal processing.
