20100174078 | Bipyridine metal complexes for use as light-emitting material - The present invention relates to light emitting materials comprising novel ortho-metalated transition metal complexes [ĈN] | 07-08-2010 |
20110215276 | Phosphorescent light-emitting material - The present invention relates to light emitting materials including a novel Ir complex, where the Ir is provided with a primary ligand selected from phenyl pyridine ligands substituted with at least one Cl atom. Such light emitting materials have been found to have a significantly enhanced photoluminescence quantum yield over other Ir complexes with a phenyl pyridine ligand having no Cl atom, or even over those with a phenyl pyridine ligand having a halogen atom other than Cl, such as a Br or F atom, and as a result specifically improve the efficiency of a light emitting device. The present invention further relates to the use of such light emitting materials and an organic light emitting device including such light emitting materials. | 09-08-2011 |

20090317189 | PROTECTION SYSTEM FOR SURFACES OF INFRASTRUCTURE IMPROVEMENTS IN A CONSTRUCTION ENVIRONMENT - A protection system comprises a body section and optional ramps for facilitating travel over the body section. The protection system may comprise base and arm members, which have bottom surfaces at different elevations to fit over an elevation change. In use, the protection system is installed over a surface to be protected, which may be a portion of an infrastructure improvement, such as a sidewalk, curb, gutter, or other structure. Traffic crossing the surface of the infrastructure improvement is then directed over the protection system, where the topical load from the traffic is distributed across the surface. When the use is complete, the protection system may be removed from the surface. | 12-24-2009 |
20130313350 | Chopping Board - A cutting board includes an opening for a rotatable disc. The rotatable disc may be inserted into the cutting board and allow a user to rotate food or other objects to be cut on the rotatable disc. This allows the user to maintain a cutting object, such as a knife, in a fixed location and rotate the rotatable disc to cut the object at varying angles. The rotatable disc can be interchanged with rotatable discs with various surfaces, such as a cutting surface for slicing or grating. The cutting board may also include a removable tray underneath the board for collecting food cut by the cutting surface. | 11-28-2013 |
