The investigations and developments of Division 17 embraced a wide 

 range of physics problems in the field of instruments including, among 

 others, land mine detectors, telemetering equipment and strain gauges for 

 airplanes, testing the production, perception and control of sound in air 

 (including sound ranging), and a concerted attack upon the problems of 

 a combat information center in naval vessels.
