When most people think of ultrasound, they immediately think of pregnancy and blurred black and white photos. But the brothers Jim and Tom Gayle of Gayle Technologies, Inc. want you to  think of their invention, the Cargate Arch.

The system, which the brothers developed from tinkering with handheld ultrasound scanners for NASCAR, detects leaks in autos during manufacturing.

The device has garnered considerable interest from auto makers. Testing for leaks normally involves the use of water booths where the vehicle is dipped into a tank of water. Unfortunately, that causes water damage. And such systems are expensive, costing $4 million each. The Cargate Arch does not cause such damage to vehicles and costs only $500,000 per system.

GM has already contacted the company.
