Abstract: Imagers and alignment methods for use by imagers imaging deoxyribonucleic acid (DNA) fragments on a flow cell are disclosed. The imagers capture intensity values at DNA fragment bead locations in tiles with each tile having a reference location in the flow cell. Flow cells may be aligned by obtaining a dark field image of each tile during a first imaging session, identifying dark field constellations of bead locations within two separate tiles during the first imaging session, identifying corresponding constellations during a second imaging session, altering the reference location of at least one tile during the second imaging session to correct for a linear offset in the corresponding constellations, and applying at least one correction factor for reading out intensity values from the imager for the bead locations in the flow cell to correct for an angular offset determined from offsets in the corresponding constellations.

Abstract: This document describes tools capable of authorizing or enabling authorization of multiple payment transactions without requiring that a buyer or seller authorize each transaction separately. The tools may do so by enabling a buyer or seller to select aggregate constraints, such as a total price or number of transactions. Based on these selected constraints, the tools may authorize every payment transaction that meets the aggregate constraints without requiring the buyer to authorize every transaction separately.
