An image of subject formed optically is obtained by the finder unit. The auxiliary layer is rastered such that nubs separated by trenches are formed. The distribution criteria may include an attribute of the type of data to be distributed, or may be based on a relationship of data with an employee that uses a data site or on a responsibility of an employee that uses a data site. The batches may be processed concurrently in a pipelined fashion to minimize the turnaround time. When the number of fast bits for a particular target is greater than a threshold, then programming stops for the non-volatile storage elements being programmed to the particular target. Such devices have applicability in through-out the body, including clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate andor mobilize the obstruction within the body lumen.
