Abstract: An all-linkage mechanism for a seating unit is provided that allows the ottoman to be extended between a closed position and an extended position, with the top face of the ottoman facing upwardly during the entire motion. The mechanism is motorized, and may be stopped in a position intermediate the closed and extended positions, such as a laptop position. The mechanism is compact, allowing use on a high-leg, wood-to-the-floor seating unit.

Abstract: A microscope slide comprises a substrate disc characterized by a top surface, and a cover glass characterized by a first surface. The substrate disc comprises a first pattern of nano-structures on the top surface; a second pattern of grooves on the top surface; a third pattern of ridges, characterized by a ridge height, on the top surface; and a fourth pattern of microfluidic guidance features. The cover glass comprises a coating of a metallic alloy with non-linear optical properties on the first surface. The cover glass is bonded to the ridges of the substrate disc to form a sealed chamber between the first surface of the cover glass and the top surface of the substrate disc, such that the ridge height determines a height of the sealed chamber. A method of fabricating such a slide and a method of optical interrogation of a fluid sample are also disclosed.
