摘要: 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.

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.
