A method of generating an optimized grammar, for use in speech recognition, from a data set or big list of items, is disclosed. The device structure provides an accurate reference voltage and a simple sensing scheme for the sense amplifier used for reading the state of a target memory cell of the FeRAM array. the first of which may include an air-pervious shroud having a plate extending from it. The lower sulfitesulfate concentration on the wafer translates into considerably less moisture pick up and prevents high aspect ratio feature collapse. The actuator is configured to create a negative pressure in the fluid reservoir and is configured to rotate the flow control mechanism from the first configuration to the second configuration after the first volume of bodily-fluid is received in the fluid reservoir.
