Abstract:

Systems and methods detect cortical arousal events from a single time-varying ECG signal that is obtained via single-lead ECG. A pre-trained deep neural network transforms the ECG signal into a sequence of cortical-arousal probabilities. The deep neural network includes an inception module, a residual neural network, and a long short-term memory neural network to identify structure in the ECG signal that distinguishes periods of cortical arousal from periods without cortical arousal.

Abstract:

Disclosed is a cartridge-based detection system to prepare an injected sample to be investigated for determination of a microbial pathogen or another analyte of interest using a detector features a field-safe cartridge. The system features a plurality of reagent chambers located within the cartridge. The system features a rotating cylindrical dial that facilitates a sequential introduction of various fluids contained in each reagent chamber into the dial whereby the fluid washes internally for contact therein. A dial channel is located through the dial. A dual window region of interrogation is centrally located in the dial. The dial is pivoted into position to fluidly connect each mated anterior and posterior reagent chamber via the dial channel. Methods of used are also disclosed.
