  • Patent number: 7496454
    Abstract: An inspection system for removably mounting to a platform movable in relation to a generally upright mast for inspection of the mast has a mounting support assembly removably fixable to the platform. The mounting support assembly for scanning the mast carries a detector device and collecting mast scanned information. A power supply is carried by one or more of the mounting support assembly or the detector device and is connected to the detector device. A communications device is carried by one or more of the mounting support assembly or the detector device and is connected to the detector device for receiving and relaying the collected mast scanned information.

  • Patent number: 6466004
    Abstract: Apparatus and method for measuring weld current utilizing Hall effect sensors. The apparatus is immune from the position sensitivity drawbacks of Hall effect sensor based current memory devices through the utilization of a radially symmetrically disposed orientation of the Hall effect sensor in combination with the utilization of a summing network responsive to the output of each such sensor.

  • Patent number: 4132937
    Abstract: A programmable manipulator apparatus having an arm movable in a plurality of axes employs a feedback signal representing the dynamic behavior of the end of the manipulator arm for use in stabilizing a positional servo loop especially where the position sensing is performed at a location on the manipulator apparatus which is physically closer to the drive apparatus than the end of the arm. The manipulator apparatus includes encoders for developing position signals representing the position of the manipulator in each of the axes which are stored in a memory. The stored digital signals are utilized as command signals and are compared with the encoder signals to develop an error signal utilized to control movement of the manipulator apparatus.
