[Differential]

Sameer,
The machine was not developed, rather it was an idea. How about a machine connected to a computer and having a shaft. You mount your gear on shaft, the machine scan's it (the same way xrox machine scans a paper) and determines gear's parameters which will be finally displayed on computer screen. Remember, this is very high level idea, and it's you who will dig out more to convert it into actuals.
