Distran

Distran develops and sells ultrasound cameras able to "see"​ ultrasounds: each of the 128 ultrasound sensors on the camera perceives incoming sounds with a slight shift of a fraction of a milliseconds. This allows the algorithms inside the camera to compute back the position of the sound source and to display it in real-time to the user. The principle is similar to antenna arrays used by astronomers or the military. Here, the device is hand-held and allows industrials to quickly spot faults such as gas leak in their installation, often comprising hundreds of kilometers of pipes and thousands of potentially leaky elements.

Beyond cost savings, this tool enables to increase industrial safety and decrease emission of green house gases.
