The present invention represents a significant advancement in the field of cooling systems for computer hardware. Techniques include determining\u2014using a non-destructive mechanism\u2014whether an item of interest is solid gold or a gold-plated object. A noise reduction circuit and edge enhancement circuit filter and edge enhance the video signal, respectively, according to the control signal. These processes are executed by a MPU 23. The reinforcement fabric is laminated to the fibrous insulation board using an adhesive material. The layers of the structure are disposed next to or parallel to one another.
