Abstract: Systems, methods and computer-readable media are provided for determining a sequential ordering of predefined transfers for transferring an object from source points of a source array to destination points of a destination array in a laboratory automation system. For each transition to a next transfer, first and second component travel costs between current and next transfer positions are determined. A transition travel cost is determined from the first and second component travel costs. The cost of each sequential ordering of the predefined transfers is based upon an aggregate of the transition travel costs for each ordering of the transfers. The resolved sequential ordering may be based upon the sequential ordering that has the lowest cost.

Abstract: Integrated modular liquid handling systems are described. The modular liquid handling systems may be customized for use in a variety of applications, including sample processing, assays, diagnostic analyses, and separation of biomolecules. The liquid handling systems may include a variety of integrated modules that provide functions including dispensing of liquids, aspiration of liquids, sensing of liquid parameters, and detection of signals.

Abstract: A magnetic coupling (20) comprises first and second coupling members (21, 23), arranged concentrically within one another. Each coupling member (21, 23), has a respective series of projecting permanent magnets (3). On each of the (5) coupling members (21, 23), each of the magnets 3 has opposite faces of opposite polarity and consecutive magnets (3) are spaced from one another with the faces of consecutive magnets (3) of alternating polarity. The magnets (3) on the coupling member (21) are disposed opposite but offset from the magnets (3) on the coupling member (23). Also disclosed is a coupling member assembled by bolts or rods (10) engaging permanent magnets (FIG. 8) and permanent magnet coupling members polarised perpendicularly to their axes of rotation (FIG. 18c).
