The invention provides a mosaic decal probe, in which a mosaic of probe chips is assembled into a thin membrane that is suspended in a ring which is made of a material that has a TCE matching that of silicon. The model of computation may be related to the synchronous statechart model of computation. The Arundo donax particulates may be combined with wood particulates to produce a mixed furnish that can be used in the preparation of composite panels. The RF amplifier detects and amplifies a focusing error signal and a tracking error signal from information on the optical disc obtained from the pickup. The invention therefore can effectively extend the useful life of many critical components and reduce downtime resulting from repair or premature replacement. The first and second sides each have first and second arcuate portions extending outwardly away from the centerline.
