20100112962	Calibration of transmit signals in fdd-transceivers - By the present invention a calibration and/or correction of transmit signals in a communication system using Frequency Division Duplex has been disclosed, in particular a method of calibration of a transmit signal to be transmitted in a device simultaneously receiving and transmitting signals in the communication system, wherein the transmit signal and the receive signal are separated by a predetermined frequency band gap. A down-conversion of the transmit signal received in the receiving path to an intermediate frequency is performed, whereby the intermediate frequency corresponds to the frequency band gap reduced by the intermediate frequency of the receive signal. A correction signal is derived from the intermediate received transmit signal and used to calibrate the transmit signal such that non-linearity effects caused by power amplifiers in the transmit path are effectively reduced. The present invention provides the advantages of an improved and simplified architecture and simultaneously of a clearly improved quality of transmit signals.	05-06-2010

20080205990	Method and apparatus - A method is disclosed that comprises the steps of preassembling the connector pipe in a support; coupling a frame to the pipeline at or towards an end thereof such that the location of at least one part of the frame is known with reference to the throughbore and the end of the pipeline; engaging the support with a portion of the frame; substantially aligning the connector pipe with the end of the pipeline; and connecting the connector pipe to the end of the pipeline. A cutting tool is also disclosed that can be coupled to a portion of a guide means and used to cut the pipeline at a predetermined distance from the guide means such that the end of the pipeline is created. A remotely operable vehicle can be used to remotely actuate and control the connection of the pipe and the pipeline.	08-28-2008
