    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.

    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： A thru-hull fitting assembly is connected to the forward end of a hollow lamp housing for mounting to a hole in the hull of a vessel in a water-tight fashion. An HID or other lamp is mounted in the lamp housing and is surrounded by a reflector which may have an outer elliptical section and an inner parabolic section. A protective transparent window extends across the forward end of the lamp housing and is sealed thereto. The window may be made of sapphire to provide improved heat dissipation and to resist scratching during hull cleaning and breakage due to thermal shock and wave slap. A circuit may be connected to the lamp to provide over-heat protection, leak detection, as well as fault and power status indicators. Alternate embodiments utilize a solid light pipe or a hollow reflective tube to convey light from the lamp to the protective window.

    摘要： A self-tuning resonator for use in a transmitter apparatus for inducing alternating currents in a buried conductor. The resonator is dynamically tuned at frequencies below 500 kHz by exploiting the inherent voltage-variability of net capacitance in multilayer ceramic capacitors. The transmitter apparatus provides improved efficiency and induced output power suitable for use in a man-portable locator system, providing a very high magnetic field output from a physically small battery-powered resonator at frequencies under 500 kHz. The resonator exhibits a very low equivalent series resistance (ESR) and is adaptively retuned to a predetermined resonant frequency responsive to any changes in resonance arising from phenomena such as component heating, thereby supporting very high tank circuit currents from battery-powered source to produce very high magnetic flux output.
