Abstract: Location systems and methods for locating paint and other markings on a surface are disclosed. A paint marking stick may include a magnetic field sonde that is actuated in conjunction with dispensing of paint or other markers, where the sonde generates a magnetic field signal in conjunction with dispensing of paint or placement of a marker. A corresponding utility locator may receive the sonde magnetic field dipole signal and determine and store positional information and type information associated with the paint or other marker.

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.
