    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.

    Abstract: This disclosure relates generally to apparatus, systems, and methods for boring in earth or other environments, both manmade and natural. More specifically, but not exclusively, the disclosure relates to devices and methods for inspecting the path of a bore (e.g., including horizontal, angular, vertical bores in 3-dimensional space) to detect any damage caused by the boring activity to infrastructure in the path of the bore. Such infrastructure may include, but not by way of limitation, gas lines, sewer lines, communication lines (e.g., fiber optic lines), electric lines, and other infrastructure. The disclosure further relates to devices and methods for mapping locations of underground objects, geological compositions, and other detectable underground features.

    Abstract: Cable handling devices, methods, and systems for securing and deploying or retracting one or more cables or hoses into or out of a pipe or cavity allowing inspection of the pipe or cavity. In an exemplary embodiment, a hand-held device with a housing for at least partially enclosing one or more cables or hoses, at least one coupling mechanism integrally attached to the housing, and a coupling control for coupling and decoupling the one or more cables or hoses is provided. The cable handling device and the one or more cables or hoses can be coupled and moved together, or decoupled enabling the cable handling device and the one or more cables or hoses to move independently of each other. One or more of the cables may be connected to a camera allowing the one or more cables or hoses to be deployed or retracted into or out of a pipe or cavity thereby facilitating inspection of the pipe or cavity.
