Abstract: Systems, devices, and methods for locating buried conductors using ambient electromagnetic signals, such as AM or other broadcast signals, are described. A buried utility locator may include a plurality of spatially separated antenna arrays, a receiver circuit coupled thereto, and a processing element programmed to process measurements of ambient electromagnetic signals and associated electromagnetic signals radiated from current induced in the buried conductor from the ambient signals to determine information about the buried conductor.

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: An underwater light or submersible luminaire may include a housing and a transparent pressure bearing window positioned at a forward end of the housing. A window supporting structure may be mounted in the housing behind the transparent window. A printed circuit board element having a plurality of LEDs may be positioned within the housing behind the window supporting structure to bear substantially all of the ambient water pressure applied to the transparent window.

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.

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.
