20100321850 | ARRANGEMENT COMPRISING A SURGE ARRESTER - A configuration includes a surge arrester. The surge arrester includes first and second connecting terminals. At least one connecting terminal is connected to an electrically conductive connecting path to contact the surge arrester. The connecting path is mounted in a universally jointed manner. | 12-23-2010 |
20130222964 | SURGE ARRESTER WITH EXTENDABLE COLLAR - A surge arrester has a collar for fixing tensioning elements. The collar is extendable and is capable of absorbing released energy in the event of a fault and holding together the cage containing the tensioning elements. The collar, which fixes the tensioning elements in the radial direction, is positioned around the cage of the surge arrester formed from the tensioning elements. The form of the collar is such that it has defined deformation regions, with the result that the collar can expand and thus widen in the event of a force effect in the radial direction. If the varistor elements expand in the manner of an explosion during an overload, the collar is expanded and absorbs some of the released energy. This ensures that the cage is held together in the event of an overload and thus no fragments of the varistor elements can be flung out of the cage. | 08-29-2013 |
20140368962 | SURGE ARRESTER - A surge arrester has a tube-shaped housing, an end fitting connected to an end of the housing, a varistor block arranged in the housing and a supporting element arranged in the region of the end fitting. The supporting element has a supporting ring which is in contact with the housing and which includes a cone and a clamping ring with a counter-cone that corresponds to the cone. The cone is braced to the counter-cone in such a manner that the supporting ring is pressed to the housing in a non-displaceable manner. The supporting element can thus also be used after the installation of the varistor block and also be removed. | 12-18-2014 |

20100214989 | Dynamic Selection By A Mobile Station Of Its Home Agent Using Its Preferred Roaming List (PRL) - Methods and systems are provided for dynamic selection by a mobile station of its home agent using its preferred roaming list (PRL). A mobile station maintains a PRL comprising an association between (i) a first set of data identifying a first wireless wide area network (WWAN) and (ii) a first identifier of a first home agent. The mobile station detects a broadcast of the first set of data by the first WWAN. Responsive to detecting the broadcast of the first set of data by the first WWAN, the mobile station connects to the first WWAN. Responsive to connecting to the first WWAN, the mobile station uses the first identifier to register with the first home agent. | 08-26-2010 |
20100296482 | SELECTION OF A COMMUNICATION DEVICE FOR A USER BY A BASE STATION IN RESPONSE TO RECEIVING A COMMUNICATION SESSION HAND-OFF - A first base station wirelessly transmits media to a first communication device for a communication session. The first base station hands off the communication session to a second base station. The second base station wirelessly transmits the media to the first communication device for the communication session. In response to the hand-off, the second base station selects a second communication device based on the type of media and transmits a prompt to the first communication device to transfer the communication session to the second communication device. In response to a user instruction, the second base station transmits the media to the second communication device for the communication session. | 11-25-2010 |
20100311401 | COMMUNICATION SESSION TRANSFER FROM ONE COMMUNICATION DEVICE TO ANOTHER BASED ON LOCATION CORRELATED TO TIME - A communication network receives communications for a wireless communication device and transfers the communications for delivery to the wireless communication device. The wireless communication device determines data that correlates its location to time. Either the wireless communication device or the communication network process the data to detect a transfer condition that comprises the wireless communication device being located within a predetermined area for a predetermined period of time. If the transfer condition applies, then the communication network transfers communications for the wireless device for delivery to another communication device. When the transfer condition no longer applies, the communication network again transfers communications for the wireless communication device for delivery to the wireless communication device. | 12-09-2010 |
20110255628 | Method And Apparatus For Interference Mitigation By Removing A Portion Of The Transmit Signal - Elimination of intermodulation interference in a wireless communication system by removing a portion of the spectrum of transmitted signals. According to a received indication of an occurrence of intermodulation interference experienced by a narrowband receiver, mappings are performed between the predetermined narrowband channel frequency on which the narrowband receiver operates and the occupied channel frequencies of at least one broadband transmit signal. Narrowband candidate frequency ranges that linearly combine into frequencies that overlap the predetermined narrowband channel frequency are determined based on the mappings. The narrowband candidate frequency ranges that potentially contribute to the intermodulation interference are then selectively filtered by at least one notch filter until the intermodulation interference is substantially eliminated. | 10-20-2011 |
20120129535 | Method and Apparatus for Providing a Pilot Beacon on Behalf of one or more Base Stations - Disclosed herein is a method and apparatus for providing a pilot-beacon on behalf of one or more base stations, such as one or more femtocells. A pilot-beacon transmitter, separate from the base stations, determines the locations of coverage areas of the base stations and then dynamically configures a pilot-beacon radiation pattern to encompass (approximately) the determined coverage areas. That way, a mobile station may detect the pilot beacon and initiate scanning of coverage provided by the base stations. Optimally, the method can be used to provide a pilot beacon for femtocells, thereby avoiding the need for the femtocells to include pilot beacon transmission functions and thus possibly decreasing the cost of the femtocells. The pilot-beacon transmitter or another entity may also be configured to receive and forward GPS signals to the base stations, possibly offsetting GPS timing based on measured delays for communication with the base stations. | 05-24-2012 |
