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: The present disclosure relates to electromagnetic marker devices for locating hidden or buried objects. One embodiment includes an antenna having a plurality of conductive windings enclosed in a housing made of a low dielectric constant material and an electronic circuit including a circuit board having circuit elements disposed thereon and electrically coupled to the conductive windings through a connector. The circuit elements receive an input signal having a first frequency from an above-ground transmitter, convert the input signal to a power supply to power up the electronic circuit, generate, in response to the input signal, an output signal having a second frequency different from the first frequency, and provide the output signal, via the antenna element, to an above-ground receiver.

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: 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.
