A semiconductor device includes a silicon substrate and a compound semiconductor layer formed on a main plane of the silicon substrate. Such measurements may be obtained at predetermined intervals within a transmitted signal or may be obtained at randomly selected intervals, and should yield measurements for each data pulse in a repeating data pattern. The data driving circuit provides plural data signals according to a data control signal. Once the initial setup is complete, the present invention automatically triggers or deactivates the filters and dynamically applies one or more filters based on the number of discovered objects and rules defined by the user. The elongate body has radial outlets which may be closed or open in alternative states, whereby these radial outlets may be used for circulating fluid in order to clean the well bore. The fibrate particles of the composition have an effective average particle size of less than about 2000 nm.
