  • Patent number: 8291780
    Abstract: An inspection sensor module for an in-line pipe inspection tool has a support for mounting the module on the tool, a finger pivotally attached at one end to the support and pivotally attached at the other end to a sensor block carrying one or more inspection sensors. A first leaf spring extends from the support to the finger to bias the finger outwardly, and a second leaf spring extends from the support to the carrier to bias the sensor block. Biasing sensors are mounted on the leading and trailing edges of the first leaf spring to detect movement of the first leaf spring corresponding to movement of the inspection sensors towards or away from the support.

  • Patent number: 8285288
    Abstract: A method of operating a user equipment, UE, intended to use a service in a wireless communication system having several base stations. The location of the UE is monitored, by the UE, for example with a GPS system or identification of the cell of the corresponding base station. If a problem, such as loss of coverage or call, is imminent or has occurred, information about the location is stored in a memory of the UE. After successful recovery from the problem, the alternative base station used is also stored in the memory. Next time the same location and problem is encountered, the UE uses the previous information for alleviating the problem or perform as fast recovery as possible. In this way, the UE can be operated with less frequent base station searches thereby saving battery, while at the same time sufficient coverage may be obtained.

  • Patent number: 8285295
    Abstract: The present invention relates to cellular communications and in particular to a frequency spectrum shared by two cellular networks. The object is flexible utilization of the spectrum. This is achieved by a method wherein a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. The invention also relates to a RRM unit arranged for carrying out the inventions, to a BSC and to a radio base station adapted for carrying out the method. One advantage is that spectrum can be lent from an old system when a new system is introduced.

  • Patent number: 8279970
    Abstract: Transmitter devices and transmission methods transmit a modulated GMSK- or EDGE-signal in a transmission system, wherein normally the pulse shaping follows the given rules of standards for these mobile radio systems. The amount of TX spectra in the adjacent TX channels is predetermined by these rules. A second filtering step is suggested to be introduced for attenuating predetermined unwanted spectra in the adjacent transmit channels. A second goal of this suggestion is to reduce spectra at adjacent TX channels also at cases of nonlinearity at the TX Power Amplifier of the RF transmitter. Nothing must be changed in standards of mobile communication systems, for example GSM.

  • Patent number: 8270534
    Abstract: A receiver (13) of user equipment, UE, (10) of a Universal Mobile Telecommunications System, UMTS, network receives a digitally encoded radio signal over a downlink (11) from a base station (12). A Digital Signal Processor, DSP, (14) of the UE (10) estimates BER of data bits of power control commands received in the signal during an out of synchronisation procedure. More specifically, the DSP (14) samples the amplitude with which the data bits are received and determines a ratio of functions of one or more moments of the sampled amplitudes. The DSP (14) then compares the determined ratio to one or more values of BER for different ratios in a look-up table to estimate BER.

  • Patent number: 8264219
    Abstract: An in-line pipe inspection tool has one or more inspection platforms (28, 30) which are connected to an elongate wheeled trolley by link arms (20 to 26). The trolley unit (10, 12) has drive means for driving the point of connection of the first link arm (20, 22) to the trolley (10) relative to the point of connection of the second link arm (24, 26) to the trolley (12), thereby to move the inspection platforms (28, 30) in a direction perpendicular to the direction of elongation of the trolley (10, 12). Thus the inspection platforms (28, 30) are movable which is relative to the trolley (10, 12) to permit the tool to be adapted to pipelines of different diameters. Moreover, the platforms (28, 30) preferably have permanent magnets which contain a rotatable magnet. The rotatable magnet permits the net magnetic field generated by the platform to be varied.

  • Patent number: 8260374
    Abstract: Mobile User Equipment (UE) is operated in a first mode in which radio functions are enabled. In response to a predetermined condition, the UE is operated in a power saving mode involving disabling all radio functionality for a first period of time during which no connection is maintained with a cellular communication system serving node. After the first period of time, the UE ascertains whether any attempts were made to contact it during the first period of time and if so whether any of the attempted contacts is characterized by an attribute that matches a predefined attribute. If any of the attempted contacts is characterized by the attribute that matches the predefined attribute, then a user alarm is activated. If the response to the user alarm has been made, then the UE is again operated in the first mode; otherwise, the UE is again operated in the power saving mode.

  • Patent number: 8254392
    Abstract: The present invention relates to a link layer control protocol implementation in a communication system. To improve operative efficiency of the link layer control protocol implementation it is suggested to delay issuance of a retransmission request for a missing data unit during a retransmission delay time period. Therefore, according to the present invention a retransmission request is not issued immediately upon detection of a missing data unit. Therefore, the present invention avoids issuance of false alarm for the missing data unit when it is received during the retransmission delay period.
