    Abstract: Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.

    Abstract: System for generating maps from magnetic field utility line estimates include one or more vehicle-mounted magnetic field sensing locators, one or more antenna nodes to sense magnetic fields emitted from buried utilities, a receiver circuit to process the antenna signals, a position and orientation element to determine the position and orientation of the magnetic field sensing locating device in a world coordinate system, a processing unit to generate at one or more discrete points an estimation of one or more utility positions and orientations, and a map generation element to generate an associated map.

    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.
