    摘要： A sonde includes an elongate flexible ferromagnetic core and a coil surrounds an intermediate segment of the core. A housing surrounds and supports the coil. An electronic drive circuit is mounted in the housing for supplying the coil with an electric signal that will induce the core to emit electromagnetic signals at a predetermined strength and frequency that can be remotely detected. Self-contained battery powered float-type and pill-type sondes are also disclosed.

    摘要： An elongate rugged cylindrical metal housing encloses rotatable forward looking and side looking video cameras for inspecting bore holes of water, oil and natural gas wells. A ring-shaped array of white LEDs is mounted on a PC board at the forward end of the housing. The ring-shaped array of LEDs surrounds, and is spaced rearward of a flat sapphire window through which the forward looking video camera views down the bore hole. The array of forward looking LEDs is encased behind a dome-shaped acrylic window which protects the forward looking LEDs from physical impacts and also functions as a light pipe. A side looking video camera is mounted in an inner tube rotatable by a motor drive within the outer housing about a longitudinal axis of the outer housing. The side field of view of the second video camera can be aligned with a predetermined circumferential region of a side wall of the bore hole for locating and inspecting defects in a well casing. A stationary cylindrical array of white LEDs is mounted in the exterior housing, surrounding the inner rotatable tube, slightly rearward of the second video camera. A light bending film with tiny Fresnel prisms is mounted just inside a cylindrical window of the housing and maximizes the amount of illumination that strikes the predetermined circumferential region. Switch mechanisms and circuitry are provided so that one or more sixty-degree circumferential segments of the cylindrical side facing array of LEDs which are adjacent the field of view of the side looking video camera are energized in order to minimize power consumption and heat dissipation. The forward and side illumination design minimizes the common illuminated volume and maximizes the resolution of the forward and side video images.

    摘要： At least one antenna array including three mutually orthogonal antennas each sharing a common center point senses an electromagnetic signal emitted by a buried object such as a utility line, pipe or sonde. A circuit at least partially mounted in a housing is connected to the array and determines a location of the buried object by measuring signal strength and field angles in three dimensions without having to align the antenna array relative to the buried object while eliminating nulls and false peaks. A graphical user interface (GUI) has user-friendly icons, symbols, menus, numbers and graphical and auditory representation of signal strength. A plurality of different underground objects can be simultaneously detected and their different locations can be simultaneously indicated to a user via audible sounds and/or visual images on a display.
