Title: Innovations of Alvin Mark Terry

Introduction

Alvin Mark Terry is a notable inventor based in Longmont, Colorado. He holds a total of 6 patents that contribute significantly to the field of medical technology, particularly in pulse oximetry.

Latest Patents

One of his latest patents is titled "Cepstral domain pulse oximetry." This invention involves the processing of plethysmographic signals via the cepstral domain. The method includes obtaining time domain plethysmographic signals, smoothing them, and performing a first-stage Fourier transformation to convert these signals into frequency domain plethysmographic signals. The process continues with computing power spectrums, scaling them with a logarithmic function, and performing a second-stage Fourier transformation to transform the power spectrums into cepstrums. This innovative approach allows for the examination of cepstrums to obtain vital information regarding a patient's physiological condition, such as pulse rate or SPO2 level.

Another significant patent is "Multi-domain motion estimation and plethysmographic recognition using fuzzy neural-nets." This invention enhances pulse oximetry by classifying plethysmographic signals through a neural network. The neural network processes input coefficients from multiple signal domains, including spectral, bispectral, cepstral, and Wavelet filtered signal domains. The plethysmographic signal is transformed from a first domain to various signal domains, resulting in a corresponding plurality of transformed plethysmographic signals. The neural network classifies the plethysmographic signal through its output layer, which is connected to the input layer by one or more hidden layers.
