A vision of perfection

Article Abstract:

KeyTronic Corp, the largest computer keyboard manufacturer in the US, has developed and installed several machine vision systems in the company's Cheney, WA assembly plant to effectively perform final inspections of products. The machine vision sytems are capable of inspecting misloaded and defective keys, thereby allowing for process quality control. The systems, composed of cameras attached to robots, use software for analyzing images and compares these with programmed patterns saved in computer memory banks. If discrepancies are found, printouts are made to identify problem keys.

Maintaining color consistency

Article Abstract:

Chevron Corp utilizes Colorcurve Systems Inc's Colorcurve technology program for controlling color consistency in designing and manufacturing various color products. The new system uses computer technology in calculating light readings of colors and formulating pigment mixtures from acquired data. Advantages of the process include more consistent and reliable color formulations resulting from precise color matching under all kinds of lighting substrates, conditions and product surface finishes.

UV chamber scatters light uniformly

Article Abstract:

A UV chamber developed by the National Institute of Standards and Technology promises to increase the accuracy of UV weathering tests by scattering UV light more uniformly over test areas than conventional instruments. UV test results may prove inaccurate in some aspects because of nonuniform scattering but the equipment's spherical design scatters light more effectively and uniformly.
