EAS102 G/H Exam 2 Spring 2006 NAME:____________________________ NOTE PROBLEM 4 TWO OPTIONS 1 for 25 points and 2 for 20 points. DO ONLY ONE OF THESE OPTIONS 1. (25 points, time estimate 12 minutes) You are designing an inspection system that needs to identify defects in circuit boards. The defect you are concerned with is the flatness of the board. If the distance that the board rises off the conveyor belt is greater than 0.05% of the minimum of the width or length of the board it has failed inspection. You have a system (shown below) that can take a picture of the board, record the relative position in the belt (number 1, 2, 3 …), measure the width, length, and maximum height (lack of flatness) from a reference plane. Develop an algorithm that takes the input, determines if the board passes or fails inspection, and would output the position of bad boards so that they can be removed in the next section of the process. camera Conveyor belt Circuit boards length width height

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
