Abstract: An assembly for optically coupling a light source and an optical waveguide having an axis of optical transmission and a generally planar end face. A connector encloses the end of the optical waveguide with the end face of the optical waveguide exposed. A housing positionable adjacent the light source defines a chamber extending along a light transmission axis and sized to receive the connector with the optical and light transmission axes coaxial. The connector is supported in the chamber in a first predetermined position by spring-biased ball plungers mounted to the housing. The balls anchor in a groove extending circumferentially in the outer surface of the connector. A lens cap has a sleeve in which the connector is received. An end of the sleeve is closed except for an opening supporting a spherical lens. The lens cap slides within the housing chamber along the axis with the end of the connector contacting the lens cap adjacent the lens opening.

Abstract: A wind-propelled craft having at least two elongated, low-profiled, flat-bottomed floats. The floats are parallelly and distally connected by a framework adapted to support the wind propulsion structure. The framework and floats are connected by fore and aft articulated joints which allow for arcuate travel of the framework and propulsion means relative to trim while maintaining level positioning of the flat-bottomed floats in relation to the medium being traversed. The floats, therefore, do not heel into the water. Resistance to the craft's speed and manueverability is thus diminished because the craft planes upon the water rather than heeling into it as is the case with conventional hulls and float assemblies.
