Scanner Work

AI Thread Summary

A scanner operates by directing a bright light at the object being scanned and capturing the reflected light with an array of light sensors, such as CCDs. These sensors convert the reflected light into electrical signals, which are then processed to create a digital image. The type of scanner can vary, influencing its specific functionality and applications. Understanding these basic principles helps clarify how different scanners work. Overall, the technology behind scanners is integral to their ability to digitize physical documents and images.

A scanner typically shines a very bright light at whatever you are scanning, and detects the reflected light with an array of light sensors like CCDs (Charged Coupled Device, like those found in a digital camera), converting them into electrical signals.

Thread '2:1 Pulley Question'

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...

Thread 'I need a concave mirror with a focal length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.
