  • APPARATUS FOR TESTING ORGANIC LIGHT-EMITTING DISPLAY APPARATUS, AND SYSTEM FOR MANUFACTURING ORGANIC LIGHT-EMITTING DISPLAY APPARATUS BY USING THE SAME
    Publication number: 20130068368
    Abstract: A testing apparatus for testing an organic light-emitting display apparatus including: a test chamber for retaining a first substrate having a plurality of exposed cells, each cell including an organic emission unit; a stage in the test chamber, the stage configured to support the first substrate; a plurality of probe bars, each of the probe bars including a plurality of probe blocks for respectively contacting the exposed plurality of cells of the first substrate to supply an external signal to the exposed plurality of cells; a probe bar moving unit coupled to the probe bar; and a probe bar supply unit including the plurality of probe bars, wherein the probe bar moving unit is configured to move a probe bar to and from the stage and to and from the supply unit to obtain and unload a probe bar.

  • Method and system for improving call drop caused by radio link failure in mobile communication system
    Patent number: 8208924
    Abstract: A method and system for improving a call drop caused by a Radio Link Failure (RLF) before handover triggering in a mobile communication system are provided. The method of improving the call drop caused by the RLF in the mobile communication system includes detecting an RLF occurring before handover triggering (RLF_before_HO), generating one of an RLF_before_HO-dependent statistics and an RLF_before_HO-dependent log file, transmitting the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file to a serving Base Station (BS), and updating a Neighbor Relation Table (NRT) and optimizing a handover parameter using the one of the RLF_before_HO-dependent statistics and the RLF_before_HO-dependent log file.
