Sleep R&D
 

Hybrid EEG Amplifier with High-Speed Impedance Checking

CRI has developed a unique single channel bio-amplifier. The amplifier has ultra-wide bandwidth (0.5Hz - 400Hz), advanced input pre-filtering for noisy environments, intergrated digitization (16-bit at 2kHz), high-speed electrode impedance checking and ultra-fast saturation recovery. Control is accomplished using serial commands (RS-232 or SPI) and runs on a single 5VDC supply.

Wake/Sleep Detection


CRI has developed an advanced, single-channel, EEG-based wake/sleep detection system (patented and patents pending). This system operates on the differential-mastoid EEG channel to determine the sleep state (i.e. awake or asleep) every 30 seconds throughout the night in real time.

Insomnia


CRI has developed a novel treatment device for chronic insomnia utilizing CRI's advanced single-channel EEG-based wake/sleep detection technology. This system enables improved in-home delivery of cognitive behavioral therapy. Click HERE to read the laboratory testing overview.


CRI initiated an in-home study of the insomnia treatment prototype devices. Click HERE to read about the in-home study.


CRI has developed the next generation of prototype insomnia treatment systems, called ZMACHINE®. Click HERE to see the first pictures.


Sleep Apnea


Analysis of one-hour nap data from early CRI human performance testing provides an indication that the sleep fragmentation / micro-arousals associated with sleep apnea may be detectable using algorithms operating on High Frequency EEG signals.
