  • Apparatus and method for monitoring a cable
    Patent number: 6873746
    Abstract: In one embodiment the present invention provides a device for monitoring a cable, comprising an imaging device having a field of view; a target, distinguishable within the field of view of the imaging device, associated with a cable; and a computer processor connected to the imaging device for analyzing images of the target produced by the imaging device to determine a position of the cable. In another embodiment, the present invention provides a method for monitoring a cable, comprising calibrating a first image of a predetermined field of view showing a portion of a cable to be monitored; capturing a second image of the predetermined field of view; correlating the first image with the second image to determine a position of the portion of the cable within the second image; and reporting said position.

  • Pump shaft inspection system
    Patent number: 4899590
    Abstract: An inspection system for non-destructively detecting physical defects in solid shafts by launching and receiving longitudinal acoustic waves has been described incorporating a transducer head containing a transducer head containing a matrix of transducers, pulsers, pulse width modulators, preamplifiers and a summing amplifier. A fiber optic cable may couple the transducer head to a remote location containing a receiver and a oscilloscope. The invention overcomes the problem of launching longitudinal acoustic waves with insufficent energy. Further, the invention overcomes the problem of asymmetric load conversions affecting the output signal arising at times when only one transducer is used and is positioned off center with respect to the solid shaft.
