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: Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

Abstract: A high pressure resistant flotation sphere includes a brittle fracture material macro-sphere of high elastic modulus and a shell of a low shear strength elastomeric material surrounding the macro-sphere. A high pressure resistant flotation material may be made of a plurality of macro-spheres embedded in syntactic foam or other matrix material, with each macro-sphere being encased in a shell of a low shear strength material that isolates each macro-sphere hydrostatically from the surrounding matrix.

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.

Abstract: Methods and apparatus for wired communications are disclosed. A method for transmitting a data stream through a wired communications channel includes encoding the data stream to produce a first baseband modulating signal I(t) and a second baseband modulating signal Q(t) whose amplitudes together represent a time series of complex symbols (I, Q) each selected from a two-dimensional (2-D) constellation of symbols distributed on the phase plane about the origin such that at least one of the baseband modulating signals has a substantially non-zero mean amplitude, modulating the baseband signals I(t) and Q(t) to produce a modulated signal, wherein the I(t) and Q(t) components of the modulated signals are generally fixed in quadrature, and providing the modulated signal to a wired communications channel.
