Method, system and device for sleep stage determination using frontal electrodes
First Claim
1. A method of sleep stage determination, comprising:
- receiving electrical potentials corresponding to biological signals from an electrode assembly positioned over a head of a patient;
processing the biological signals to determine EEG signals, EOG signals and EMG signals;
calculating, with a processor, a pre-score based on the EEG signals, the EOG signals and the EMG signals and a plurality of rules;
using said processor for determining based on said plurality of rules and said pre-score whether the sleep stage can be categorized by the pre-score;
checking whether a sleep stage has been categorized based on said pre-score using said processor; and
when said checking step determines that the sleep stage could not be categorized based on said pre-score, determining the sleep stage based on at least one epoch.

Abstract
The described embodiments relate generally to methods, systems and devices for sleep stage determination using frontal electrodes. Certain embodiments relate to a system for sleep stage determination comprising a sensing unit and a processing unit. The sensing unit is positioned over a forehead area of a patient and has first, second and third electrodes for positioning at locations on or adjacent the forehead area for detecting electrical potentials of a human head. The processing unit is coupled to the sensing unit for receiving biological signals corresponding to the detected electrical potentials and processing the biological signals to determine a sleep stage of the patient. The processing of the biological signals is based on a plurality of rules.
