The Challange

Identifying potential coronavirus symptoms, using a set of contactless sensors, in order to prevent people with the virus from entering public places such as hospital emergency rooms.

The Solution

The development of a rapid remote diagnostic system that can measure certain metrics at a distance of a few meters away from the operator. This will allow people to be tested at a safe distance before gaining entry to a public place. The device will measure pulse, breathing rate, temperature, oxygen saturation, eye redness and use a laser-based optical stethoscope.

Current status

Measuring pulse and breath: integrated an existing prototype of an optical microphone to remotely measure pulse and breath. Tests from 5 meters away were successful with minimal discrepancies (+/- 5% for pulse rate and +/- 1 breaths per minute for the breathing rate).

Temperature: temperature was successfully measured from 4.5 meters away using a thermal imager, together with an algorithm that determines the point on the body from which to measure the temperature. Initial tests showed an accuracy of within 0.3 degrees.

Oxygen Saturation: Currently in development - a prototype will be complete in a couple of weeks.

Optical stethoscope: A prototype was built, signal-to-noise ratio is still too low.

What’s Next

Eye Redness: testing for eye redness/conjunctivitis will be done using video and an algorithm which was already developed. 

Optical Stethoscope: Continue working to refine the optical stethoscope which was tested using a laser at a distance of 2 meters. Initial testing revealed too much background noise.
