    摘要： An apparatus for connecting tubulars comprises tongs for gripping the tubulars, having openings which can be aligned to allow tubulars to enter the tongs, and a detection apparatus for detecting the location of a joint between the tubulars. The detection apparatus comprises a set of keys disposed along an axis substantially parallel to the axis of the tubulars, the keys being individually displaceable on contact with the tubulars as the tubulars enter the tongs through the openings. The detection apparatus further comprises a set of sensor means, each arranged to detect displacement of a corresponding key. The position of the joint can then be determined from the displacement of the keys.

    摘要： A torque sub for use with a top drive is disclosed. A method of connecting threaded tubular members for use in a wellbore includes operating a top drive. The top drive rotates a first threaded tubular member relative to a second threaded tubular member. The method further includes measuring a torque exerted on the first tubular member by the top drive. The torque is measured using a torque shaft rotationally coupled to the top drive and the first tubular. The torque shaft has a strain gage disposed thereon. The method further includes wirelessly transmitting the measured torque from the torque shaft to a stationary interface; measuring rotation of the first tubular member; compensating the rotation measurement by subtracting a deflection of the top drive and/or the first tubular member; determining acceptability of the threaded connection; and stopping rotation of the first threaded member when the threaded connection is complete or if the threaded connection is unacceptable.

    摘要： The present invention provides a method and an apparatus for assessing a capability, for example, linearity of an amplifier, such as that of a power amplifier including a radio frequency amplifier. In one embodiment, the method comprises defining a first figure of merit for a power amplifier based on a loss of linearity relative to a predefined linearity requirement for the power amplifier and/or defining a second figure of merit based on the first figure of merit and dependent upon a minimum frequency within a predefined frequency band for the power amplifier, characterizing the linearity thereof. In this manner, using a test setup, for digital mobile communication networks deploying one or more higher order modulation schemes with complex wireless transmission that results in non-constant envelope signals, linearity of power amplifiers in transceivers, such as a mobile station or a base station, may be sufficiently described. Moreover, the two defined figures of merit may be used to compare different amplifiers for these higher modulation schemes, making possible a comparison of different amplifiers independent of their implementation technology or design structure.
