| 20100082630 | PERSISTING EXTERNAL INDEX DATA IN A DATABASE - Systems, methods, and computer program products to persist external index data in a database are disclosed. In an embodiment, a method includes maintaining a database including a first data table that is configured to store data in a database format and a second data table that is configured to store index data. The index data represents an index of a first portion of the first data table, and the index maintained externally to the database by an index manager. The method also includes generating a data update representing a modification to the first data table and communicating the data update to the index manager. The method further includes receiving index update data from the index manager representing a modification to the index as a result of the data update and applying the index update data to the second data table. | 04-01-2010 |

| 20090294788 | LIGHT EMITTING DEVICE WITH A NON-ACTIVATED LUMINESCENT MATERIAL - The invention relates to a light emitting device having a radiation emitting element, for example a light emitting diode, and a luminescent material which is able to absorb a part of the radiation sent out by the radiation emitting element and to send out light with a wavelength which is different from the wavelength of the absorbed radiation. The device further has diffusing particles which are able to scatter a part of the radiation sent out by the radiation emitting element, and/or to scatter a part of the light sent out by the luminescent material. The diffusing particles are of non-activated luminescent material, through which production is simplified. | 12-03-2009 |
