摘要： A novel connection port is described for connecting a signal transmitter to an apparatus configured to wirelessly communicate video and images from a pipe inspection system. Such a connection port may establish an electrically conductive pathway to a push-cable and camera head further disposed in cable storage drum that the wireless communication apparatus may couple thereto. A signal transmitter, having an established electrically conductive pathway to the push-cable and camera head, may transmit electromagnetic signals that may be emitted by the push-cable and camera head and further be located at the ground surface via a utility locator device.

摘要： Cable storage drum-reel and cable guide apparatus, methods, and systems are provided for deploying and retracting at least one push-cable with a distally mounted camera into and out of a pipe or cavity for applications such as plumbing and underground utility location. In an exemplary embodiment, a cable guide assembly may include a bracket, and one or more wear guides positioned with openings in the bracket. The one or more wear guides may include two spaced-apart wear guides each having an opening defining an inner diameter. In one embodiment, the spacing between the two wear guides may be a distance of three or more times the inner diameter of the wear guides.

摘要： 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.

摘要： 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.
