A glucose monitor having only a test strip reader and wireless transmission to a remote hand held calculation processor. For example, a method includes inputting data signals to FFE taps of a current-integrating summer circuit, wherein the data signals are time-delayed versions of an analog input data signal. The data processing system determines whether a mismatch exists between a search result for the text in the document and the log of research. The ear tip is suitable for in-ear operation and can have a cosmetic deformable outer member. When the alumina layer is the uppermost layer, it may be wet-blasted to an Ra value of <about 1 \u03bcm, giving the tool a black and shiny appearance. This enables an intact plate-shaped member to be obtained by stamping.
