A system is described for maintaining synchrony of operations among a plurality of devices having independent clocking arrangements. The drive of the outer mass pump is integrated into the inner mass filling machine. The switches can be FET, MOSFET and optical switches, and can be selectively closed when the element radiates or receives RF energy to selectively establish connectivity between the conductive segments, which can achieve a selective Yagi-like effect for the antenna. A linear circuit interpolatesdecimates an approximation of the compressionexpansion filter coefficient function based on the slope value, the initial discrete value and a preselected set of low order bits of the reciprocal value. Fluorescent detection analytes comprise a fluorophore moiety, a covalent linker moiety, and a SAM-utilizing protein ligand moiety and could be utilized in FP or TR-FRET assays to measure test compound binding. The program window of the next program is then resized to occupy the entire display.
