Abstract: Buried utility transmitters and associated locator devices, systems, and methods used for locating utility lines, pipes, and/or other conductors that are obscured from view are disclosed. In one embodiment a buried utility transmitter includes a module generating an output current for provision to the utility so as to generate a magnetic field for detection by a utility locator, with the output current signal having modulated signaling. The transmitter system may include a tray apparatus configured to be removably dockable to the transmitter module or element or a body or frame of the transmitter system.

Abstract: Various finger tip controlled manual interface devices that can be used as inputs to personal computers, electromechanical systems and video game consoles utilize concentrically arranged magnets. The polarities of the magnets are oriented to provide restoration forces on a one of the magnets to bias it toward a neutral position. A magnetic sensor including a plurality of sensing elements such as Hall effect devices generates output signals representative of direction and amount of movement of the magnet that is biased to the neutral position.

Abstract: Systems and methods for electronically marking, locating, and virtually displaying buried utilities are disclosed. According to one embodiment, one or more electronic marker devices may be placed below a ground surface in proximity to a buried utility, and marker device data indicative of position and/or identity of such electronic marker devices may be obtained. The obtained marker device data may be associated to the utility data and stored in a database. The stored data may thereafter be retrieved based in part on the marker device data for use in subsequent locate operations and/or for other purposes.
