20110177820 | TELECOMMUNICATIONS SYSTEM AND METHOD - The present invention overcomes the problem of S1 interface failure by redirecting user equipments to another radio basestation, or another RAT. This redirecting may be on a UE-by-UE basis, i.e. when a connection request is received, redirecting that UE, or may involve redirecting all UEs in a cell by broadcasting modified system information. The redirecting may be such that future traffic load, for example as caused by UEs performing tracking area updates, is minimized, by instructing UEs to redirect after a randomized period of time, or by locking the cell after a randomized period of time, for example. In yet further embodiments of the invention, the cell may be locked after a certain number of connection requests have been received. In this way, particularly busy cells can be locked sooner than would otherwise be the case. | 07-21-2011 |

20120040816 | CENTRIFUGAL SEPARATOR - The invention relates to a centrifugal separator comprising a casing which delimits and seals off a space in which a rotor is arranged. The rotor forms a separation space which is sealed or isolated from the space, and in which separation space centrifugal separation of a higher density and a lower density component from a fluid takes place. An inlet extends into the rotor for introducing fluid to the separation space, and a first outlet extends from the rotor for discharge of a component separated from the fluid. The space is connected to a pump device which is arranged to remove gas, thereby maintaining negative pressure in said space. The rotor comprises at least one second outlet extending from the separation space to the space for discharge of at least one higher density component separated from the fluid. The invention also relates to a method in such a centrifugal separator. | 02-16-2012 |

20150290660 | CENTRIFUGAL SEPARATOR - A centrifugal separator for separation of particles from a gas stream is disclosed. The centrifugal separator includes a self-supporting frame for mounting inside an existing vessel for guiding the gas stream. The frame comprises a holder configured to hold the frame at a position inside the vessel, and a first partition for dividing the vessel into a first section and a second section. The first section is upstream of the second section. The separator includes a gas inlet communicating with the first section, and a gas outlet communicating with the second section. A centrifugal rotor is arranged to be rotatably supported in the frame around a rotational axis, the rotor having a first and a second end portion and including a plurality of separation plates defining separation passages between the plates. The centrifugal separator is configured such that the first and second sections communicate via the separation passages of the rotor. | 10-15-2015 |

20130333972 | Pedestrian Airbag Arrangement - A pedestrian airbag arrangement for a vehicle includes an airbag covering at least a part of the windscreen and/or at least a part of at least one A-pillar of the vehicle when it is in deployed state, an inflator in fluid connection to the airbag, and a retraction means for retracting the airbag. The retraction means includes a triggering means and a retractor retracting the airbag when released by the triggering means. In order to provide an automatic retraction of the airbag, the triggering means is activated by the airbag. | 12-19-2013 |
