    Abstract: Flexible magnetic cores for generating magnetic fields in a utility locator system sonde are disclosed. The flexible core includes an elongate resiliently deformable rod and a flexible elongate structure of a high permeability ferromagnetic material disposed around the elongate resiliently deformable rod, with the resiliently deformable rod comprising fiberglass rod or similar resilient materials, and the flexible elongate structure comprising a plurality of bundles of wires of a high permeability/low loss ferromagnetic material.

    Abstract: Apparatus for magnetically sensing, computing, and displaying cable distance, as well as computing and displaying other user-selectable information in a pipe inspection system or other system is disclosed. Two or more permanent magnets may be mounted in spaced apart fashion, on either a frame or a rotatable member supported on the frame for rotation about an axis. A magnetic sensor may be mounted on the other one of the rotatable member or frame on which the magnets are not mounted, so that either the magnets rotate around the magnetic sensor or the magnetic sensor rotates between the permanent magnets. The magnetic sensor may generate output signals representing changes in at least two axes in a composite magnetic field generated by the permanent magnets.
