20110110292 | METHOD OF TRANSMITTING A COMMUNICATIONS SIGNAL - A method is provided for sending a communications signal in a communications network having a plurality of nodes assuming alternating sleeping and waking states and in which a sender node executes a step of sending an initial preamble, prior to sending data to a destination node. The method includes at least one operation of a neighbor node of the sender node relaying the initial preamble, where a relaying operation corresponds to sending a preamble formed from the preamble sent during the preceding relaying operation, the preamble sent during the first relaying operation being formed from the initial preamble, and the at least one relaying operation continuing until the destination node for the data detects the sent preamble. | 2011-05-12 |

20110110294 | VIRTUAL CARE-OF ADDRESS FOR MOBILE IP (Internet Protocol) - An IP (Internet Protocol) session for a mobile node is carried out through the use of a virtual care-of address. A foreign agent sends an agent advertisement to the mobile node to allow the mobile node to choose from a list of IP addresses of the foreign agent. To perform virtual care-of address services, the foreign agent ties the virtual care-of address to a mobile node so that an intelligent and dynamic selection of tunnels to be used for the IP session can occur. Therefore, traffic for an IP session is not limited to transmission over the single particular tunnel that corresponds to an IP address initially selected by the mobile node. Rather, the virtual care-of address shifts the tunneling decision from the mobile node to the foreign agent. Supporting multiple tunnels between home agent and foreign agent allows resilience, redundancy, and service-level differentiation to mobile node traffic without involving the mobile node in the process. | 2011-05-12 |

20110110311 | Exchange of Scheduling Strategies for Interference Coordination - A cell informs surrounding cells about an orthogonal resource allocation strategy of the informing cell so as to induce cooperative behavior among the cells. The informing cell also receives resource allocation strategies from the surrounding cells. Each cell allocates its orthogonal resources according to the mutually exchanged information. The result is to reduce interference in the system. For example, a BS informs other cells on which clusters it generates a small interference, e.g., close UEs concentrated into a particular cluster, and indicate that to its neighbors. Other cells would concentrate UEs which are on the edge to the indicating cell exactly in this cluster. This would mean an “overload invitation”, i.e. inviting the neighbors to produce overload on a particular cluster. If a cell sends an overload invitation on a sufficiently large cluster, this will automatically reduce the interference in the other clusters. | 2011-05-12 |

20110110390 | LASER DIODE STRUCTURE WITH INTEGRATED TEMPERATURE-CONTROLLED BEAM SHAPING ELEMENT AND METHOD FOR GAS DETECTION BY MEANS OF A LASER DIODE STRUCTURE - The invention relates to a laser diode structure, specifically for use in gas detection, with a hermetically sealed housing with electrical connections having a bottom and a window. A laser diode chip and a temperature control system for the laser diode chip are provided in the housing. A thermo element in the form of a Peltier element forms the temperature control system, and is connected via a lower flat surface to the bottom of the housing and via an upper flat surface to the laser diode chip, with a temperature-controlled beam shaping element as collimator provided between the laser diode chip and the window of the housing that acts on a laser beam emerging from a laser aperture of the laser diode chip before it passes through the window. The beam shaping element is in contact with the laser diode chip and is preferably connected via a boundary surface to the laser aperture with surface-to-surface contact or adhesively, or is made in one piece together with the laser aperture. | 2011-05-12 |
20110110391 | SEMICONDUCTOR LASER DIODE HAVING WAVEGUIDE LENS - Provided is a semiconductor laser diode having a waveguide lens. The semiconductor laser diode includes at least one first waveguide having a narrow width, at least one second waveguide having a wide width wider, and at least one waveguide lens having an increasing width from the first waveguide toward the second waveguide and connecting the first waveguide to the second waveguide. Sidewalls of the waveguide lens connecting the first waveguide to the second waveguide may be curved. The second waveguide may be a waveguide providing an optical gain. | 2011-05-12 |
