Inventor: LEE JEONG-WOO
IPC: H04B1/30
Filed: 2002-03-27
Abstract: A wireless or wired communication system and method is provided including a transmitter and a receiver. A RF communication system in accordance with the present invention includes an apparatus and gain control method between RF receiver (803) and baseband modem (804) in case of a plurality of gain stages (830, 846, 862) inside a receiver (803). The gain of each stage (830, 846, 862) can be controlled by an integrated gain controller (828). The gain controller (828) monitors the signal level of each gain stage (830, 846, 862) to place its gain to optimal value. The gain control apparatus and method can be implemented in a digital AGC system. The gain controller (828) accepts a signal (826) implementing gain control and thus there is no stability issue. When distributed gain stages are present inside a related art receiver and separate gain control loops are used, stability issues can arise.

Inventor: JACKSON STEPHEN L
IPC: E21B43/10
Filed: 2002-08-29
Abstract: An apparatus and method of creating a seal between two coaxial tubulars so as to create a hanger and a packer. A first tubular (200) is disposed coaxially within a portion of a second, larger tubular (400). A portion of the first tubular is expanded into frictional contact with the second tubular, thereby creating a liner and a hanger. In one embodiment, a pattern of grooves (210) and profile cuts (205) is formed in the surface of a portion of the first tubular body. The grooves and profile cuts in one aspect define a continuous pattern about the circumference of the tubular body which intersect to form a plurality of substantially identical shapes, such as diamonds. The grooves and profile cuts serve to improve the tensile strength of the tubular body. At the same time, the grooves and profile cuts allow for expansion of the tubular body by use of less radial force. The grooves and profile cuts further provide a gripping means, providing additional frictional support for hanging the expanded tubular onto the inner surface of a surrounding second tubular.  Carbide inserts (220) are preferably interdisposed within the pattern of grooves, providing additional gripping means when the smaller diameter tubular body is expanded into the second tubular.

Abstract: In general, an apparatus including a lead body and at least two electrodes.  The lead body is so shaped that the lead body brings the first electrode against cardiac tissue yet keeps the second electrode away from contact with the cardiac tissue. These electrodes may be separated by a very small distance. When the lead is implanted in the superior vena cava, each electrode generates a distinct voltage signal as a function of sensed electrical activity. Although each electrode may sense a far-field R-wave in addition to a P-wave, the difference between the signals from the electrodes preserves the P-wave but includes a reduced far-field R-wave.

Abstract: Methods and apparatus for spinning a pipe using a flexible belt. The spinner utilizes a single actuation mechanism contained within a rigid body to engage the pipe and tension the belt. The pipe is engaged by one or more pivoting arms that are locked into place by pins attached to the actuation mechanism interfacing with slots in the pivoting arm and spinner body. Once the arms are locked in place, the belt is tensioned and can be driven to rotate the pipe. The single actuation mechanism is preferably embodied by a linear actuator connected between a pivoting arm and a moveable motor. The pivoting arm is spring biased so that the arm pivots before the motor is moved. The spinner may use two pivoting arms, or one pivoting arm and one stationary arm.
