Abstract: A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.

Abstract: An edge lit fixture. A light engine comprises a compartment and at least one elongated lens that are attachable to a mount plate. The mount plate, an exterior surface of the compartment, and the lens define an internal optical cavity. A light strip is mounted to the mount plate within the optical cavity. One or more legs can be used to attach the fixture to an external surface, such as a ceiling T-grid. The light engine can be used with legs of varying size such that it can fit within ceiling openings having different dimensions. The assembled fixture defines an open area. One or more light engines are arranged around or through the open area such that light is emitted into the open area. The open area of the fixture allows for existing materials, such as a ceiling tile, for example, to function as a back side reflector panel.

Abstract: Lighting retrofit systems and methods are disclosed that can be used with different light fixtures, but that are particularly adapted for use with retrofitting troffer-style fixtures with LED based light engines. The retrofit systems being assembled without disturbing the lighting or troffer pan or housing (“troffer pan”) for the lighting system being retrofitted. Some of these embodiments can comprise a mounting fixture or frame that can be mounted in an opening in a ceiling grid, and held in place between the grid and the troffer pan edge. The fixture or frame can comprise an opening for a light engine, with the engine being quickly and easily connected to electrical power in the troffer pan and then mountable within the frame opening. These embodiments can allow for the quick and easy construction of the retrofit system without the need for adhesives and fasteners such brackets and screws.

Abstract: A luminaire comprises a frame and a plurality of optical waveguides retained by the frame. The optical waveguides bound a cavity, and each comprises: a top end and a bottom end opposite the top end; a coupling portion disposed at the top end; an inner side facing the cavity; and an outer side opposite the inner side. The inner and outer sides are disposed between the top and bottom ends. The luminaire further comprises at least one light emitting diode (LED) associated with each optical waveguide. Each of the LEDs are disposed opposite, and configured to direct light into, the coupling portion of the associated optical waveguide. Each optical waveguide is configured to receive the light via the coupling portion and emit the light primarily from the outer side.

Abstract: Frame and lens upgrade kits for lighting fixtures. A frame bracket defines the frame area, which can be rectangular, for example. A lens frame fits just inside the frame bracket with the lens frame being releasably attached thereto. The frame bracket can be constructed from collapsible frame bracket subassemblies. For example, a rectangular frame bracket may be assembled from first and second collapsible frame bracket subassemblies that fan out and lock together to create a rigid frame bracket. The subassemblies each comprise elongated side and edge brackets that are fastened together such that they can pivot about one another. In some embodiments, one side of the lens frame is attached to a corresponding side of the frame bracket with a rotatable clip that allows the lens frame to swing such that its other side can attach to the bracket frame with an attachment latch, which can be magnetic, for example.
