Title: Innovations by Chris Hettinger
Introduction
Chris Hettinger is an accomplished inventor based in Worcester, MA (US). He has made significant contributions to the field of health technology, particularly through his work on photoplethysmogram (PPG) signal analysis. With a total of two patents to his name, Hettinger is recognized for his innovative approaches to predicting vital signs.
Latest Patents
Hettinger's latest patents include groundbreaking technologies for predicting respiratory and heart rates from PPG signals. The first patent focuses on respiratory rate prediction, utilizing an artificial neural network model trained on a dataset containing PPG data. This model incorporates convolutional layers to eliminate artifacts from the PPG signal, a fast Fourier transform (FFT) layer to convert the signal into frequency representations, and a dense layer to decode these representations into respiratory rate predictions. The trained model can then process PPG data from a pulse oximeter to output accurate respiratory rate predictions.
The second patent addresses heart rate prediction using a similar methodology. This technology also employs an artificial neural network model, which is trained on PPG data to predict heart rates. The model's architecture mirrors that of the respiratory rate prediction patent, featuring convolutional layers, an FFT layer, and a dense layer. After training, the model can analyze PPG data from a pulse oximeter to provide reliable heart rate predictions.
