20110003556 | METHOD FOR DETERMINING IF A FIRST CELL MANAGED BY A FIRST BASE STATION IS NEIGHBOUR OF A SECOND CELL MANAGED BY A SECOND BASE STATION - The present invention concerns a method for determining if a first cell managed by a first base station is neighbour of a second cell managed by a second base station, the cells being cells of wireless cellular network, the wireless cellular network comprising a telecommunication network enabling the transfer of information between the base stations. The first base station monitors the amount of information transferred between the first base station and the second base station through the telecommunication network and determines if the second cell managed by the second base station is neighbour of the first cell managed by the first base station according to the amount of monitored information transferred between the first base station and the second base station through the telecommunication network. The invention concerns also the associated device. | 01-06-2011 |
20120058793 | FIRST BASE STATION MANAGING A NEIGHBORING CONDITION AND CELL AREA OPERATION OF A CELL AREA, SERVER OF A WIRELESS CELLULAR NETWORK, AND SYSTEM FOR MANAGING A NEIGHBORING CONDITION AND CELL AREA OPERATION OF A CELL AREA - The present invention concerns a first base station managing a neighboring condition and cell area operation of a cell area, the cell area being a cell area of a wireless cellular network, the wireless cellular network comprising a telecommunication network enabling a transfer of information between the first base station and a second base station, where the wireless cellular network comprises a server linked to the telecommunication network. | 03-08-2012 |

20120002162 | METHOD FOR CUTTING A PATCH TO BE APPLIED ONTO A CURVED SUBSTRATE - A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film. | 01-05-2012 |
