Abstract: In a cellular communication system, for example UMTS using WCDMA, a configuration of radio links is controlled. In a mobile unit, and in a base station, a synchronization counter indicates time codes (CFN) for synchronization of configuration changes across the system. Messages are exchanged between a network controller, the base stations and the mobile units, which messages include a change command (62) for changing a configuration, and a reconfiguration command (61) for changing a current configuration state to a next configuration state at a selected future time code (63). Traditionally a prepared reconfiguration period (67) for such a reconfiguration change was treated as a blocking period for further changes. According to the invention the prepared reconfiguration period is determined, and a prepared reconfiguration period indicator (66) is added to the change command. Hence other configuration changes can be effected during the prepared reconfiguration period.

Abstract: A method of and apparatus for bending and tempering a sheet of glass heated to a formable state provides an improved rigid mold and pressing member for pressing the heated sheet against the rigid mold which cools and bends the sheet. The pressing member includes a conformable pressing element which permits a manifold to be positioned between the rigid mold and the pressing member to direct a gas to cool the heated sheet of glass during bending. The conformable pressing element is pressurized into a convex shape for initially pressing on a portion of the heated sheet and for rolling the heated sheet onto the rigid mold. The rigid mold and the conformable pressing element may each include a cover to increase the heat transfer from the heated sheet to the bending and tempering apparatus. Furthermore, the covers may have increased thermal conductivity in their peripheral regions for increased cooling of the edge of the sheet of glass.

Abstract: A method of and apparatus for bending a sheet of material heated to a formable, state such as glass, resinous polymeric material, viscoelastic material, and thermoplastic material, provides an improved pressing member for pressing the heated sheet against a first rigid mold which reduces the size of the buckles in the bent sheet, eliminates the need for a second rigid mold, reduces the process control steps, reduces the risk of damaging the rigid mold, increases the tolerances for the positioning of the sheet in the apparatus, and increases the range of application. The pressing member includes a flexible diaphragm which rolls the heated sheet against a rigid mold by first applying a pressure to a portion of the heated sheet and then radiating the pressure from that portion to the remaining surface area of the heated sheet in a rolling action. The bending apparatus includes a rigid mold and a flexible diaphragm pressurized into a convex shape for initially pressing on a portion of the heated sheet.

Abstract: Apparatus and method for testing an optical element sample such as a mirror simultaneously and substantially instantaneously both for the total amount of light reflected from and the total amount of light transmitted by a predetermined area of that sample. The apparatus includes a pair of axially aligned light-integrating spheres between which is clamped the test sample so that no light enters or escapes from either sphere. A preferably optically regulated, substantially collimated beam of light is directed through one sphere against the test sample at an angle to the sphere axis. Silicon photo-voltaic light sensitive detectors connected to amplified readout units indicate the total light reflectivity in one sphere and the total light transmission to the other sphere.
