Title: Innovations of Eugene Seagriff in Noise Cancellation Technology
Introduction
Eugene Seagriff is a notable inventor based in Edison, NJ (US), recognized for his contributions to noise cancellation technology. With a total of 5 patents, he has developed innovative methods to improve audio signal clarity by effectively reducing unwanted noise.
Latest Patents
One of his latest patents focuses on "Noise cancellation using segmented, frequency-dependent phase cancellation." This method involves acquiring a digitized noise signal and utilizing a digital processor circuit to subdivide the noise signal into different frequency band segments. By generating a plurality of segmented noise signals, the processor applies time shifts and amplitude scaling to each segment, ultimately combining them to create a composite anti-noise signal that abates noise through destructive interference.
Another significant patent is titled "Noise cancellation with improved frequency resolution." This technique enhances noise cancellation by acquiring a digitized noise signal from an environment containing an audio signal stream. The method includes appending additional samples to the data sample, computing a frequency domain representation, and converting it back to the time domain to form an anti-noise signal. This signal is then output into the audio stream to effectively reduce noise.
Career Highlights
Eugene Seagriff has worked with several prominent companies, including Silencer Devices LLC and Matsushita Electric Industrial Co., Ltd. His experience in these organizations has contributed to his expertise in developing advanced noise cancellation technologies.
Collaborations
Throughout his career, Eugene has collaborated with notable individuals such as Jean-Claude Junqua and Raihan Ferdous Sajal. These partnerships have likely enriched his work and led to further advancements in his field.
Conclusion
Eugene Seagriff's innovative work in noise cancellation technology has significantly impacted the audio industry. His patents demonstrate a commitment to improving sound quality and reducing unwanted noise, showcasing his expertise as an inventor.
