Systems, devices, and methods for drain cleaning using high voltage, high frequency AC electrical power supplied through a video push-cable are disclosed. In one embodiment, a drain cleaning system may include a cable for carrying electrical control and/or data signals as well as alternating current (AC) power at a high voltage and high frequency relative to AC mains frequencies.

High frequency AC-powered drain cleaning and inspection apparatus and methods

Buried object locator systems including transmitters and associated buried object locators using phase-synchronized signals are disclosed. A transmitter may generate output current signals that are phase-synchronized with a timing reference for detection by a corresponding buried utility locator that is phase-synchronized with a second timing reference.

Phase-synchronized buried object transmitter and locator methods and apparatus

A buried utility locating system includes a transmitter circuit including electronic circuits to generate keyed current signals for coupling to the buried utility including a signal generation module and an output current signal generation module, a direct or inductive coupling apparatus, and an associated utility locator for sensing magnetic field signals radiated from a buried utility and decode keying therein.

Keyed current signal utility locating systems and methods

Buried object locator systems including transmitters and associated buried object locators using phase-synchronized signals are disclosed. A transmitter may generate output current signals that are phase-synchronized with a corresponding locator for improved utility locating.

Utility locating systems using keyed magnetic field signaling are disclosed. the systems include a utility locating transmitter for generating and outputting one or more different keyed current output signals, where the keyed signals include data defining a utility type or designator a locator sub-system, and corresponding utility locators for receiving keyed magnetic field signals resulting from flow of the keyed output current signals in the utilities and determining locate information and utility type information from the received magnetic field signals.
