  • Publication number: 20230077875
    Abstract: An approach for collecting disparate data within a pipe involves a sensor arrangement configured to be deployed within the pipe. The sensor arrangement includes a plurality of sensors configured to detect disparate data related to the pipe. Each sensor of the plurality of sensors is coupled to a respective collection computer on the sensor arrangement. A synchronization module is configured to synchronize the disparate data. A database is configured to store the synchronized data. A processor is configured to process the synchronized data. A user interface configured to present the synchronized data to a user.
    Type: Application

  • Patent number: 11193896
    Abstract: Systems and methods for determining cross-section profiles of underground fluid conveyance structures involves a memory configured to store a profile scan dataset of at least one pipe and at least one pipe template. A processor is configured to compare the profile scan dataset to one or more templates. Profile deviations in a pipe profile are determined using the comparison. A location and an areal measurement of the profile deviations is determined. A user interface is configured to present the profile deviations to a user.

  • Patent number: 7200464
    Abstract: An improved servo system for galvanometers, scanners and similar devices which uses digital processing to increase the dynamic range and provide greater effective resolution. The system provides digital control of a reference point that directly influences the excitation, which in turn directly influences the gain of the circuit. A high and low resolution switching path is provided to optimize dynamic range. Wide angle torque compensation improves uniformity of response at large angular deflections from zero. Improved thermal protection allows safe operation near system thermal limits. A graphical user interface allows adjustments and changes response on the fly for tuning due to input conditions or user control.
