Performance Evaluation of the Circadia Contactless Respiratory Monitor and Circadia Sleep Analysis Algorithm

Abstract—The current study aims to evaluate the performance of the Circadia Sleep Analysis Algorithm, which - in combination with the non-contact and minimally invasive Circadia bedside monitor - allows for long-term sleep assessment and continuous evaluation of sleep therapy outcomes. The Circadia Contactless Respiratory Monitor was initially used to record 17 nights of sleep data from 9 ...

Inside the Gas Analyser – the Interferometer

Several of OPSIS gas analyser types utilize the DOAS technology to establish the concentration of gases. To do so, we need access to absorption spectra in different wavelength regions. A fairly ...

Windowless, Back Illuminated CCD Sensors

We do not have a wafer fab or foundry for making CCD sensors at McPherson. We buy these cameras. A CCD array detector can speed up data acquisition of spectra – collecting a whole spectrum in the time scanning acquires one point. Direct detection CCD sensitivity is better in the soft x-ray, extreme and vacuum ultraviolet (response graph below). CCDs enable rapid data collection, imaging ...
