Abstract: Described are concepts directed toward systems, structures and techniques to create low-resistance, high current capacity, demountable solder joint connections. Such systems, structures and techniques may be used to simultaneously create low-resistance, high current capacity, demountable solder joint connections at multiple locations between no insulation (NI) superconductors and in particular between NI high temperature superconductors (HTS) such as may be used in NI-HTS magnets.

Abstract: This invention relates to dermatology and to treatments of infectious skin disease.

Abstract: A light assembly includes a light source, a first lens and a first lens holder coupled around the light source holding the first lens in a fixed position relative to the light source. A second lens and a second lens holder are rotatably coupled to the first lens holder holding the second lens optically adjacent to the first lens. The second lens holder and the second lens are rotatable relative to the first lens and the first lens holder.

Abstract: A light fixture assembly includes an elongated tray comprising a base comprising a first side, a second side and a first opening therethrough. The elongated tray further includes a first longitudinally extending wall extending from the second side of the base and a second longitudinally extending wall extending from the second side of the base. The first longitudinally extending wall has a first coupler. The second longitudinally extending wall has a second coupler. The light fixture assembly has a light assembly and a coupling assembly coupling the light assembly to the tray. The coupling assembly is positioned around the opening and adjacent to the second side around the first opening. A baffle is coupled within the coupling assembly.

Abstract: A light fixture has an elongated track comprising an upper channel comprising a first wall having a first slot and a second wall having a second slot. The assembly has a support assembly comprising a base and a swivel arm rotatably attached to the base at a swivel. The base comprising a first flange received in the first slot and a second flange received in the second slot, said base extending across the upper channel. The swivel arm has a first end and a second end. The swivel is disposed at the first end and a cable connector is disposed at a second end of the swivel arm. The cable connector receives a cable therein.

Abstract: An intelligent weightlifting apparatus includes a frame including vertically oriented members and safety rails that are selectively moveable up and down relative to the vertically oriented members. The apparatus includes a position sensor that is configured to detect a position of a barbell. The apparatus includes a computer that is configured to control movement of the safety rails based on data from the position sensor such that a predefined distance is maintained between the safety rails and the barbell during a free weight exercise.

Abstract: An assembly for an opening through a member has a body and a first spring retention assembly coupled to the body. The first spring retention assembly has a first coil spring at least partially disposed within a first spring housing. The first coil spring has a first end extending through the first spring housing and is coupled to the body. The first coil spring is extendable from and retractable into the first spring housing.

Abstract: Edge-lit lighting systems employing a light module for mounting a LED light source with ease of installation and removal on fixtures are described where the frame for the lighting system bears an internal skeletal pre-load bar to keep the frame planar. Multiple frames may be combined with alignment plates and joining hardware and a suspension system that gives the fixtures stability, strength and great functional advantages when used in various forms of architectural lighting.

Abstract: A joining system for light fixtures where one fixture attaches to the next without the need for tools or access to the interior of the fixture. The spring bolt joining system can be used with all styles of linear and non-linear fixtures. A few examples of the mounting styles that work with this joining system: suspended mounted fixtures, surface mounted fixtures, recessed mounted fixtures and wall mounted fixtures.

Abstract: A low-profile screen which allows water to pass through apertures formed therein to allow water to drain through the screen. A plurality of ridges are formed on the surface of the screen to allow water to drain at a number of different elevations, to increase the structural rigidity of the screen, to improve snow-melting, and to improve the screens reliance when compressive forces are exerted on the screen. Under compression the screen snaps into place. The ridges further promote debris being blown off of the surface of the screen.

Abstract: Lighting fixtures with one or more reflectors, paired with a lighting source providing indirect light from one or more apertures in one sphere above or below the system and direct light from one or more apertures in another sphere above or below the system providing efficient lighting for various uses is described.

Abstract: Animation coordination system and methods are provided that manage animation context transitions between and/or among multiple applications. A global coordinator can obtain initial information, such as initial graphical representations and object types, initial positions, etc., from initiator applications and final information, such as final graphical representations and object types, final positions, etc. from destination applications. The global coordination creates an animation context transition between initiator applications and destination applications based upon the initial information and the final information.
