Abstract: A collapsible wine carrier has front and rear panels, and a pair of side panels which each include a front edge and a rear edge connected by a corner hinge, which together form a rectangular enclosure. Each of the side panels is formed of a pair of half panels which are connected together with a middle hinge, which enables the side panels to move between an expanded configuration and a collapsed configuration. The carrier further has a top panel that includes at least one bottle top receiving recess, and a bottom panel bottle bottom receiving recess. There are first engagement features for removably engaging the top panel with a top edge of the front, rear, and pair of side panels when the pair of side panels are in the expanded configuration, and second engagement features for removably engaging the bottom panel with a bottom edge of the front, rear, and pair of side panels, when the pair of side panels are in the expanded configuration.

Abstract: A laser beam steering apparatus includes a beam steering cell with an adjustable shape, with the cell having opposing Fabry-Perot filters, and a steering mechanism coupled to the cell to adjust its shape so that the direction of a laser beam emitted from the cell is changed in response to a change in the cell shape.

Abstract: An optical system employs an optical coating on a substrate positioned relative to an optical collection system. The thickness of the coating is tailored such that light perceived by the collection system over prescribed angles of acceptance has a spectral content that is unchanged, or changed in a prescribed manner, from that entering the system when the sensor is oriented in the “look ahead” direction. The thickness of the coating is varied so that the wavelengths transmitted or reflected correspond to those required by a specific application. The invention is adaptable to system requirements that are centered about a single wavelength, or that require multiple wavelengths. The optical coating can take any of a number of forms, including stacked dielectric layers and rugate filters.
