Touch-free life-sign monitoring by videocamera
4 September 2006
CNOGA Inc. has developed contact-free physiological
monitoring by using a simple video camera. The new technology can detect a
person’s pulse rate, blood pressure, blood O2, CO2 and
more from a distance by focusing on the patient’s skin.
The new technology opens vast applications for remote patient monitoring
and diagnostics applications. CNOGA is developing a line of monitoring
devices for professional and home use and is planning to receive regulatory
approval during 2007.
CNOGA technology is based on novel bio chrominance information processing
acquired from the video camera image sensor. The company says the technology
can go beyond monitoring basic life-signs and detect the development of
disease-specific bio-markers for heart failure, COPD, cancer, renal
diseases, liver disease and more.
The new remote sensing technology will
enable the identification of early development of diseases and change in
status of chronically ill patients, as well as emotional and physiological
