Method and apparatus for evaluating data representing a plurality of excitations of a plurality of sensors

A method for evaluating data expressed as a plurality of sensor-excitation pair entries representing a plurality of excitations of a plurality of sensors;

• the method comprising:
• (a) storing said plurality of sensor-excitation pair entries in an information store;
• (b) substantially simultaneously for each respective sensor-excitation pair entry of said plurality of sensor-excitation pair entries:
• (1) exercising a fit relationship employing a first sine value to determine a fit value;
• (2) ascertaining a measure of fit error between each said respective sensor-excitation pair entry and said fit value;
• (3) employing said measure of fit error to estimate a next sine value;
• and
• (4) employing said next sine value to perform a fit optimization operation with each said respective sensor-excitation pair entry;
• and
• (c) repeating step (b) until a desired number of said sine values has been exercised.

An apparatus for evaluating test data from a plurality of excitations of a plurality of sensors;

• the apparatus comprising:
• (a) an information store for storing said test data as a plurality of data entries;
• each respective sensor-excitation pair being a respective data entry;
• and
• (b) an evaluation unit coupled with said information store;
• said evaluation unit exercising an iteration of a fit relationship employing at least one first sine value to determine a fit value substantially simultaneously for at least a portion of data entries of said plurality of data entries;
• said evaluation unit ascertaining a measure of fit error between said test data and said fit value for at least said portion of data entries;
• said evaluation unit employing said measure of fit error to estimate at least one next sine value;
• said evaluation unit employing said at least one next sine value to perform a fit optimization operation with said test data substantially simultaneously for at least said portion of data entries;
• said evaluation unit repeating said ascertaining a measure of fit error, said estimating at least one next sine value and said performing said fit optimization operation until a desired number of said sine values has been exercised.
