Remote commissioning for an automation system enables a retailer to sell a new device to a customer pre-configured to work together with devices that are already a part of the user’s automation system. An electronic device case is formed of two housings, each housing having integrated snaps, channels, or other retaining features used to secure the housings together. The inventive method employs a damascene-gate processing step and a chemical oxide removal etch to fabricate such MOSFETs. The computer generates a display image data including a blurred image on the basis of the color data of each pixel stored in the calculation buffer.
