• We decided to develop concept “B”

Our Solution!

How it works

6 different laser detectors read the precise time when the paper passes underneath. Advantages of using 6 lasers.

Using the simple formula: Velocity = Distance/Time

This design calculates the speed up to 15 times! This makes our design extremely accurate and reliable.

Advantages of Our Design Simple

Generic formula Reliable

Can still compute velocity even if one laser fails Very Accurate

Computes the average speed at different locations Easy instillation

Reasonably compact Few Components.

Design Features

Design features 1- Simple to install 2- Easy to replace parts. 3- Low power usage 4- Safe to operate 5- Very high accuracy 6- Measures velocity up to 15 times! 7- Can order packages with 2, 4, or 6 lasers.

Conclusion

Thank you for kindly not falling asleep during the duration of our presentation

Good Luck on your Finals and have a great winter break!
