Lumineye has developed a portable (small-size and weight) 3D-printed radar device that uses signal analysis software to differentiate moving and breathing humans from other objects, through walls. Using pulse radar technology in a form of echolocation - the means whereby bats and dolphins communicate - signals sent by the machine are timed withthe unit's software able to determine the approximate size, range and movement characteristics of a signal, how faraway and if the person is moving/breathing. In open-air use, the device can detect humans out to 50 feet. If signal must pass through a wall or other barrier, distance is shorter. With facilities San Mateo, CA and Boise, ID, the firm's graduated from the Y Combinators Summer 2019 class, Lumineye management anticipate usage by a range of users - private and public sector and the military
