W artykule zaprezentowano układ scalony pozwalający na bezinwazyjny pomiar nasycenia krwi tlenem, oparty na zjawisku różnego stopnia absorbcji światła w zależności od długości fali świetlnej oraz stopnia natlenienia krwi (oksymetria optyczna). Powstał on jako część systemu monitorowania podstawowych parametrów życiowych człowieka. Zawiera analogowe bloki nadajnika i odbiornika oraz cyfrowy blok odpowiedzialny za kontrolę pracy układu, wstępną obróbkę sygnału oraz komunikacje z innymi elementami systemu za pośrednictwem interfejsu SPI. Układ został wyprodukowany w technologii UMC 130 nm.

The integrated chip allowing non-invasive measurement of blood oxygen saturation basing on the difference in the degree of light absorption depending on the wavelength and the degree of oxygenation of blood (puls oximetry) is presented. It has been developed as a part of the system for monitoring of the human vital signs. The circuit contains an analog transmitter block, an analog receiver block and a digital block for controling the operation of analog blocks, pre-processing the signal from the receiver unit and communication with other system components through the SPI interface. The chip has been fabricated in UMC 130 nm technology.

In 2011 ITAM has completed work conducted with WIML's representatives to develop a comprehensive method of psycho-physiological pilots' signals and external environmental parameters during a test flight. It has been assumed that data will be collected "off line" during a training flight and stored in the monitoring module's memory, and after the flight it will be loaded to the operator's station system at the airport. The "On line" transmission of chosen parameters directly into a database and ongoing observation have also been anticipated. One of the main assumptions for the system was its independent work from the avionics systems of aircraft used for training. This has made it possible to use the system regardless the type of aircraft equipment and without having the necessity to stringent criteria of aviation hardware acceptance. The recording system has been designed as a distributed system consists of modules carried by the pilot, those placed permanently in the cockpit of the plane, a station for test flight preparation and reading recorded data, as well as a database system accessible via the Internet. Communication between the various system modules is to employ various transmission systems, wired as well as wireless. For safety reasons wireless communication between modules in the cockpit was not used in flight, with the exception of GSM transmission used to transfer selected data directly to the Central Acquisition System.
