A system includes multiple edge devices configured to be operatively coupled to a switch fabric. The measurement device, includes a carrier body which supports the measurement device and is connected with a contact area with a mounting area of one of the two objects and with a scanning arrangement connected with another one of the two objects and scanning the measurement device along a measurement direction. The apparatus is further comprises of a function generator that generates cyclic signals in the Megahertz range that drives the transducers at one or more of their resonance frequencies. At least one of the first and second video streams is buffered and lost or corrupted video frames associated with the first video stream are replaced with uncorrupted video frames from the second video stream. These metal plates could also be used concurrently with a seal ring for better protection during sawing.
