When Tilted Channel Implant is performed on transistor precursor structures having an etch-defined gate length and a trim-defined sidewall thickness, mass production deviations may cause errors and cause shifts in the lateral placement and implant depth of TCI dopants. The determined impedance data are processed by a representation processor that estimates diastolic and systolic transvalvular impedance representations. The controller receives a first data packet and determines whether or not any of the packet processors have been previously selected to process the first data packet based on a classification of the first data packet. One or more tuning rods or similar structures are positioned in the blade to increase the blade’s stiffness to substantially match the stiffness of the shaft. The porous shaped calcium phosphate article of the present invention may be used as a tissue-engineered scaffold, medical implant or a reinforcing constituent of a composite.
