  • Patent number: 8915611
    Abstract: A luminaire providing wide angle up lighting using light wells is provided. The luminaire can include a frame having a center plate and side walls. LED modules can be disposed adjacent to opposite side walls such that the LED modules are oriented towards each other. The luminaire can include light wells positioned over each of the LED modules such that light emitted by the LED modules may be reflected within the light wells until it is transmitted by a lens region of the light well at a wide angle relative to the nadir of the luminaire. The light wells can include reflective layers disposed on all surfaces surrounding the LED modules, and a transmittance lens region through which light, emitted by the LED modules as point sources, can exit the fixture as a surface of light. Light emitted by LED modules and light wells disposed on opposite sides of the luminaire can provide a bat wing distribution of up light.

  • Patent number: 8802361
    Abstract: The present invention provides a perfusion solution comprising specific metabolic agents, antioxidant agents, and membrane stabilizer agents that can help improve preservation, organ viability, and in some cases recover organs that would otherwise being unusable for transplantation. In a further embodiment, the perfusion solution can be used in combination with hypothermic machine perfusion. It has been found that combination of the perfusion solution and hypothermic machine perfusion can help prevent or reduce further damage to the organ and restore the organ's anti-oxidant system, stabilize the cellular cytoskeleton and cellular membranes, inhibit arachidonic acid pathway, provide oncotic support, reduce interstitial edema formation, and help restore energy stores within the organ. As a result, the method can be used to improve the viability of otherwise marginal donor organs.

  • Patent number: 8602604
    Abstract: This is directed to a lens for use with a LED light source. The lens can be placed on a top surface of a light fixture to direct light emitted by a LED module at a wide angle relative to the top surface of the fixture. The lens can include an elongated trench in which several LED light sources can be placed in a line such that light emitted within the trench is re-directed by the lens. The lens can include one or more knobs extending over the trench to facilitate diverting emitted light in a more lateral direction, as opposed to vertical direction. In some cases, the lens can be constructed using an extrusion process by which a lens having a constant cross-section allowing for a wide angle radiation pattern is provided.
