Deep Learning Algorithm for Detection of Cortical Arousal During Sleep
This invention is an end-to-end deep learning algorithm to detect cortical arousals during sleep using a one-night single lead electrocardiogram (ECG) signal. It is used to accurately detect arousal in home sleep tests, by reducing the false negative rate. The model combines both convolutional neural networks (CNN) and recurrent neural networks (RNN). Background: Sleep...

Intelligent Multi-Beam Medium Access Control in Ku-Band for Mission-Oriented Mobile Mesh Networks
The Problem: There are existing similar technologies, but these technologies are not designed for mobile mission-oriented applications. The use of Ku-band frequency on two separate information transmission levels reduces interference common with current multi-beam antennas. Also, the Ku-band frequency is not the currently used frequency range...
