The only real difference is the quality of the connected devices. Things like hubs, routers, and switches in industrial environments must be able to stand up to shock, vibration, and …

Understanding electromagnetic interference sources in touchscreens

Summary: Vadim Konradi of Silicon Labs reviews the various EMI problems associated with projected-capacitance touchscreens  in today’s portable devices. The author then outlines design and optimization techniques to deal with the interference coupling paths.  A projected-capacitance touchscreen is capable of precise touch location based on a light finger touch to the screen. It determines finger position by measuring miniscule changes …
