Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the category?Automated optical sorting technology
2. What is the primary applications?Food processing (grains, beans, nuts, seeds), recycling, mining, pharmaceuticals, and chemical industries
3. How does a bean machine sort beans?The machine drops beans onto a moving path. As each bean passes a lighted spot, a camera takes a picture. The computer looks at the picture and checks if the bean is the right color or shape.
4. Why does the machine use light and cameras?Light helps the camera see the beans clearly, and the camera takes a picture that the computer can read. The computer then uses smart rules to tell if the bean is good or not.

Optical Sensors: Devices that detect and measure light, used to capture visual data of items being sorted.
CCD/CMOS Sensors: Types of digital image sensors used in cameras and scanners to convert light into electrical signals.
Actuation Mechanism: The physical component (e.g., air jet, mechanical arm) that physically separates or ejects items based on sensor data.
Signal Processing: The manipulation and analysis of digital data received from sensors to make sorting decisions.
