A rigid flexible printed circuit board and a method of fabricating the same. The mechanism receives measured data from the plurality of devices, calculates prediction data by using the measured data and correlation information used for deriving prediction data for correlated devices, and provides the measured data and the prediction data. Moving the first frame part causes the push-pull mechanism to move the second frame part. A cap is mounted relative to the substrate assembly and defines one or more apertures so that an antechamber is defined by the cap and the conductive membrane. Trade orders are categorized in real-time as \u201chigh touch\u201d or \u201clow touch\u201d.
