| 20100215934 | COMPOSITION, PROCESS AND INSTALLATION FOR THE CONTINUOUS PRODUCTION OF A FOAMED POLYMERIC SHEET AND SHEET THUS PRODUCED - The present invention describes a process and respective installation for continuous production of foamed polymeric sheets by extrusion, another object of the invention being the development and use of polypropylene-based formulations comprising linear polypropylenes and branched polypropylenes. The installation includes four stages: a first stage of extrusion foaming, in which a foaming agent, either of a chemical or physical nature, in the latter case introduced in supercritical conditions, is mixed with the polymeric mass melted previously in the first stages of the extruder, the material expanding exactly at the outlet of the lips of the planar extrusion head; a second stage of calibration and cooling of the foamed sheet, in which the expanded plastic material is cooled by contact in a system of vacuum calibrators and by contact with water in a cooling bath; a stage of collection of the foamed panel; and a final stage of cutting of the foamed sheet, defining the final dimensions thereof. | 08-26-2010 |

The sandwich panel produced has a thickness between 7 and 40 mm, an overall density of 400-700 kg/m | 08-26-2010 |

| 20110019629 | Selecting a Transmission Technology - The present invention discloses a method for selecting a transmission technology (MIMO or non MIMO) for a HSDPA connection established between a RNC and a UE depending on the mobility of said UE, measured at the RNC as variations of the position of the UE. Then, if the connection is established with HSDPA MIMO technology and the position variations exceed a first pre-defined threshold, the connection is switched to HSPDA non MIMO technology. Also, if the connection is established with HSPDA non MIMO technology and the position variations are below a second pre-defined threshold, the connection is switched to HSPDA MIMO technology | 01-27-2011 |

| 20110077019 | Dynamically Allocating Carriers - To determine which traffic and terminal types and in which parts of a call should be best served by a given carrier there is provided a method and system for dynamically allocating carriers in a MIMO network using S-CPICH. The consideration of which carrier to allocate addresses problems caused by the enablement of the diversity transmission technique. Carriers are dynamically allocated to terminals in a WCDMA network scenario taking into account each terminal's vulnerability to interference from a carrier using S-CPICH or STTD according to certain parameters, such as a requested service or the radio conditions at any given time. The carriers are allocated from carriers using P-CPICH, S-CPICH and/or STTD. The invention also relates to a system that implements this method in a WCDMA network. | 03-31-2011 |

| 20110085614 | Selecting Transmission Technology for Communications in Wide Area Mobile Networks - Method and RNC for selecting transmission technology when a UE enters the network, which checks whether the UE is MIMO and, if so and only one carrier is available, allocates its traffic to said carrier and uses a S-CPICH to provide all MIMO traffic with a diversity pilot and Virtual Antenna Mapping for balance. If more than one carrier is available, the number of UEs, their radio conditions and load of carriers are checked periodically. If the carrier is busy only with MIMO and its load is higher than the load of the remaining carriers, diversity CPICH of STTD is selected; otherwise and only if the UEs vulnerable to STTD with good radio conditions exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network from transmitting MIMO traffic with STTD to using MIMO with S-CPICH or vice versa dynamically by periodical check of the load and UEs criteria for configuration change. | 04-14-2011 |

| 20110122962 | PHASE DIFFERENCE IN A MOBILE COMMUNICATION NETWORK - A system and method are described for detecting and controlling the phase difference introduced to radio signals by transmission branches of a transmission system in a mobile communication network. Periodically a calibration signal is generated at an input of the transmission branches during a phase calibration mode. The phase difference introduced by the two transmission branches is detected by detecting the phase difference between the calibration signal, which has at least partly passed through the first transmission branch and the calibration signal, which has at least partly passed through the second transmission branch. The phase difference between the radio signals is controlled based on the detected phase difference. | 05-26-2011 |
