    Abstract: A wellbore evaluation system evaluates mechanical wear and corrosion to components of a well system including a production tubing string positionable in a well and a sucker rod string movable within the production tubing string. A deviation sensor determines a deviation profile of the production tubing string in the well, and a rod sensor senses and measures wear and corrosion to the sucker rod string as it is removed from the well to determine a rod profile. A data acquisition computer is in communication with the sensors for computing and comparing the deviation profile and the rod profile as a function of depth in the well. A 3-dimensional image of wellbores, with isogram mapping, may be generated and examined over the internet.

    Abstract: A system for wafer handling employing a complex numerical method for calculating a path of wafer travel that controls wafer acceleration and jerk, and results in maximum safe speed of wafer movement from a first point to a second point. Motion is begun along a straight line segment while accelerating to a first path velocity. During this acceleration, the system computer calculates a series of straight line segments and interconnecting sinusiodally shaped paths over which the wafer is to be guided to the second point. The straight line segments and sinusiodally shaped paths are calculated so as to minimize total path length and the time required to move the wafer from the first point to the second point. The system computes the point of entrance and exit to and from each straight and sinusoidal path.

    Abstract: Apparatus for high resolution imaging of a moving object comprises a source of low coherence light, an optical coherence tomography imaging instrument or a dual channel, optical coherence tomography/confocal imaging instrument, a transverse scanner, an interferometer, depth adjustment means, and interface optics. First and an optional second sensing blocks sense the axial and respectively the transverse position of the object. A splitting element is shared so that the interface optics and the sensing blocks have a common axis of light transmitted to and from the object. Timing means establishes a timing, and timing intervals and reference times for images as they are taken. The acceptability of each scanned image is determined according to predetermined criteria. A series of en-face OCT images, or of longitudinal OCT images of the object may be taken at different depths or transverse coordinates, and the stack of collected images is used to build 3D profiles of the object.

    Abstract: A VGA is provided that is designed to reduce or even eliminate entirely variations in phase response/shift with changes in gain. Compensation is made for parasitic capacitances of elements in the VGA that would otherwise cause variation in phase with changes in gain. An additional capacitance is introduced to the VGA to compensate for the sources of the parasitic capacitance. The technique for introducing the additional capacitance depends on the source of the parasitic capacitance being treated. The additional capacitance is introduced to one or more of transistor amplifier circuits in the VGA, wherein each transistor amplifier circuit has a different gain and one of the transistor amplifier circuits is selected depending on the desired gain of the VGA. These compensation techniques equalize the phase response of the transistor amplifier circuits (each having a different gain) so that regardless of which transistor amplifier circuit is selected, the phase shift will be substantially the same. These techniques may be applied to each VGA stage of a multi-stage VGA system.

    Abstract: OCT apparatus includes an interferometer, having an input beam splitter and a 50/50 output splitter. The splitting ratio of the input splitter may be optimized depending on the source power of light source and on the mismatch of the balanced receiver. The input splitter is a plate beam-splitter to minimize the stray reflected light in the interferometer and allow sequential operation of the apparatus in the OCT or in the confocal regime. The switching between the two regimes may be at will, or synchronous with the en-face scanning which results in quasi-simultaneous OCT/confocal imaging or in alternatives frames, confocal and OCT. By using polarization sensitive elements, two channels are provided in each regime, OCT and confocal. The two confocal polarization sensitive channels may allow adjustments of compensators prior to OCT measurements or OCT imaging.
