  • Publication number: 20120326103
    Abstract: Organo-metallic complexes for opto-electronic and sensory devices and their use in such devices are provided. The organo-metallic complex (triplet emitter) consists of a metal center and chelate ligands. At least one of chelate ligands comprises an aromatic or fused aromatic ring(s). Each ligand is covalently substituted with at least one, preferably two charge transport groups (ctg). The metal center can be coordinated by a spectator ligand. Presence of two ctgs at each ligand is advantageous for applications in organic light emitting diodes (OLEDs). Charge transport units facilitate hole and/or electron transport to the molecular center and allow for efficient exciton formation directly on the complex. Presence of ctgs on each ligand provides good shielding with respect to interactions with the environment. Emission quenching is strongly reduced and materials with high emission quantum yields are obtained.

  • Patent number: 8185455
    Abstract: A system for auditing telecommunication billing data comprises a rule-construction user interface and an audit component. The rule-construction user interface comprises a plurality of rule condition parameter menus to construct an audit rule for at least one telecommunication billing attribute. In a particular embodiment, before baselining the audit rule, a user can test rule conditions against actual data, and the user can compare multiple versions of a single audit rule to determine which version successfully identifies exceptions. The audit component is to perform an audit of a telecommunication billing data set for exceptions to the audit rule constructed using the rule-construction user interface. Once identified, the exceptions can be assigned to additional tool users to assist in exception investigation and maintenance using an exception maintenance component.

  • Patent number: 7548851
    Abstract: A musical jukebox is disclosed which provides for: fast archiving of songs; a flexible user interface; easy and convenient entry of, access to and/or display of data relating to songs archived by the jukebox; easy and convenient search and locate capabilities for locating, reviewing, retrieving and/or playing songs stored in the jukebox; and low cost relative to the functionality, features, conveniences and user-friendliness provided by the jukebox. Fast of flush archiving of songs (as well as other data and signals) is accomplished by first saving sets of data without compression, which allows the data to be entered quickly, and then, compressing later at an appropriate time. A unique MP3 bit allocation encoding scheme is used to compress data. A unique memory allocation supports fast data archiving. The user interface employs two-way communication between a remote control and the jukebox. A searchable song database is structured to enable very fast searching by music category, and also by title and artist.
