    Abstract: Multi-frequency buried object location system transmitters and locators are disclosed. A transmitter may generate and provide output signals to a buried object at a plurality of frequencies, which may be selected based on a connection type. Corresponding locators may simultaneously receive a plurality of magnetic field signals emitted from the buried object and generate visual and/or audible output information based at least in part on the plurality of received magnetic field signals. The visual and/or audible output may be further based on signals received from a quad-gradient antenna array.

    Abstract: A pre-amplifier circuit for connection to an antenna of a human-portable locator includes a differential amplifier/mixer pair and means for allowing a common-mode “phantom” signal to modulate a transfer function of the differential amplifier/mixer pair. The common-mode phantom signal modulates the transfer function of the differential pre-amplifier “onboard” the antenna without the usual requirement for onboard power supply and signal oscillator. This technique uses the same electronic components to provide both pre-amplification and mixing functions, thereby improving circuit performance-to-cost ratio, reducing mixer power consumption, situating the necessary signal oscillator remotely from the mixer, and greatly improving the available system bandwidth by limiting spectral transmission demands to the mixed signal bandwidth alone.

    Abstract: Camera heads and associated rotating contact assemblies are disclosed. In one embodiment a slip-ring assembly includes a rotating contact assembly including slip rings having a cylindrical ring assembly and a flexible or bendable brush assembly. Brush elements may flexed to remain in contact with corresponding ring assembly electrical contacts. Bush contacts may be coated or have attached contact assemblies to increase hardness and oxide resistance with materials such as palladium nickel, rhodium, or hard gold, though a variety of other materials may be used as a suitable coating.

    Abstract: A pipe guide includes a pair of cylindrical shells each having a plurality of radially extending circumferentially spaced vanes and structure for holding the shells together when the shells are axially mated end-to-end. A pair of curved tab arms extend circumferentially about corresponding ones of the cylindrical shells. A pair of slide-locks are configured to slide over corresponding ones of the tab arms to move them into a locking position in which keys on the tab arms extend between adjacent coils of a coil spring surrounded by the shells.
