Abstract: Apparatus for obtaining depth profile information from a transparent object, includes a confocal scanner for producing an en-face image of the object in an x-y plane, a spectral optical coherence tomography (OCT) apparatus for producing an OCT scan along at least one line in the z direction passing through a point in the x-y plane, and a display device. A processing unit displays on the display device the en-face image and an indication of the position of the point so as to permit the location of the OCT scan to be determined on the en-face image. The position point can be adjusted by the user when viewing the image. In other embodiments, SLO and OCT images are produced from a common aperture, and spectral OCT images are produced simultaneously with fluorescence images.

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: 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.
