Title: John Leonard Semmlow: Innovator in Cardiac Signal Detection
Introduction
John Leonard Semmlow is a notable inventor based in New Brunswick, NJ (US). He has made significant contributions to the field of cardiac signal detection, holding a total of 7 patents. His work focuses on developing innovative apparatuses for diagnosing heart diseases through the detection of high-frequency heart sounds.
Latest Patents
One of his latest patents is titled "System and means for estimating the signal-to-noise ratio of acquired signals." This invention presents an apparatus designed for the detection of high-frequency heart sounds, which is crucial for diagnosing heart diseases. It utilizes an accelerometer-based detector that applies a light load to the chest, ensuring sensitivity to the desired high-frequency range. The apparatus provides a quantitative measurement of the quality of the acquired signal. Additionally, it employs two piezoelectric sensors that respond to the same mechanical energy, producing identical electrical signals in the absence of noise. Through advanced signal processing, these signals can estimate the signal-to-noise ratio and can be combined to enhance the overall quality of the acquired signal.
Another significant patent by Semmlow is the "Apparatus for detection of cardiac acoustic signals." Similar to his previous invention, this apparatus is designed for detecting high-frequency heart sounds for diagnosing heart diseases. It features a lightweight mechanical structure that supports two pairs of flexible beams, each equipped with piezoelectric transducers. These beams are center-loaded to ensure they respond uniformly to mechanical energy, producing identical electrical signals when noise is absent. The invention is designed to be lightweight, sensitive to higher frequencies, and relatively immune to noise.
