Abstract: The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such data in the conduct of an assay by an assay system. The present invention also relates to consumables (e.g., kits and reagent containers), software, data deployable bundles, computer-readable media, loading carts, instruments, systems, and methods, for performing automated biological assays.

Abstract: An ophthalmic device having rim members for securing a pair of primary lenses thereto for distant vision, the upper portion of the rim members being located above eye level when worn, at least one pair of auxiliary lenses being tensionally and releasably attached to the device in a piggy-back arrangement, and extending over the primary lenses, preferrably over the rear thereof, and of such a prescription so that the prescription of the combined lenses, primary and auxiliary, provides a bifocal or multifocal lens arrangement, the means for releasably attaching the auxiliary lenses to the rim member being a pair of bracket members attached to the side portions of the rim members, at least one of the bracket members being resilient and capable of spring action, so that at least one of the bracket members will yield relative to the other bracket member, the auxiliary lenses having notches formed in the side portions thereof, the bracket members and the notches in the auxiliary lenses being arranged so that the au

Abstract: A contact lens comprising at least two components, one of the components is made of a relatively hard optical material, the other component being made of a hydrophilic material and arranged to extend at least partially over the inner surface of the hard component in the form of a peripheral ring, so that a central zone thereon is uncovered and the ring of hydrophilic material, when in a hydrated state, extends rearwardly of the central zone of the hard component, whereby a void is provided between said central zone and the cornea when the lens is placed in position on the cornea, whereby only the hydrophilic component contacts the cornea.

Abstract: A contact lens made of a relatively hard, non-hydrophilic material, arranged to re-surface the major portion of the cornea of the eye, said lens being provided with a liner made of a hydrophilic material which is arranged to cover a portion of the lens, so that only the hydrophilic liner comes in contact with the eye.
