Abstract: Systems and methods for locating and/or mapping buried utilities are disclosed. In one embodiment, one or more magnetic field sensing locating devices include antenna node(s) to sense magnetic field signals emitted from a buried utility and a processing unit to receive the sensed magnetic field signals may be mounted on a vehicle. The received magnetic field signals may be processed in conjunction with sensed vehicle velocity data to determine information associated with location of the buried utility such as depth and position.

Abstract: Embodiments of video inspection systems with moveably dockable camera control units (CCUs) which may include a display are disclosed. In one embodiment, a video inspection system includes two frame elements which each have a handle. The frame elements may be moved into multiple positions and orientations relative to each other and provide a secure stand for a CCU. The CCU may be attached and detached from the frame elements. The handles may be used to carry the frame elements with or without the CCU attached. The handles may be slip resistant to provide a stable support for a CCU when the frame elements are positioned on a surface. Docking apparatus are provided to allow a CCU, tablet, pad, laptop, or smartphone to be attached to the frame elements and put in a variety of positions or orientations to make viewing convenient for a user.
