Abstract: A system may include (a) at least one key map variant which has a plurality of key values associated with corresponding keystrokes; (b) a character encoding chart which has a plurality of code values associated with corresponding characters of the character encoding chart; (c) an input data reader which receives input data. The input data contains at least one of the code values associated with at least one corresponding character of the character encoding chart. The system may also include (d) a translation table which translates the at least one of the code values of the input data into at least one of the key values associated with at least one corresponding keystroke.

Abstract: An apparatus for calculating fluid flow in a channel including a very low profile probe which detects fluid depth in the channel; a mechanism for measuring average fluid velocity in the channel; a mechanism for correcting the detected fluid depth based upon the measured average fluid velocity to account for drawdown; and a mechanism for calculating average flow rate based upon the average fluid velocity measurement and the corrected fluid depth value. The probe has a height to width ratio of less than 0.52.
