摘要： A ground tracking system including a ground follower assembly for use with a locator or other device for determining position, motion, and/or orientation information is disclosed. The ground follower assembly may include a wheel assembly coupled to a locator and configured to swivel and/or pivot relative to an antenna node of the locator to generate signals for use in determining position information during a locate operation, such as from a sonde array.

摘要： An antenna useful in an antenna array of a man-portable buried utility locator includes a flexible bobbin made of copper foil. The bobbin has a plurality of axially spaced grooves and an axially extending gap formed therein. A layer of insulation surrounds an outer surface of the bobbin. A conductive wire is disposed in the grooves and wound around the bobbin over the layer of insulation to form a plurality of axially spaced sub-coils. A layer of copper-foil tape having an insulating backing is wound about the conductive wire and has a second gap aligned with the gap in the bobbin. A layer of a low dielectric material is wound about the copper-foil tape. The antenna provides more antenna wire surface for an equivalent coil cross-sectional area, compared to prior art antennas, thus yielding greater sensitivity. The construction of the antenna provides a series of Faraday-shielded sub-coils, which yield a greater useful antenna bandwidth by moving the inherent resonance of each coil to a higher frequency. The construction of the antenna also reduces inherent winding capacitance and provides a self-shielding effect that further improves sensitivity.

摘要： Magnetic locators for detection of buried objects, such as ferromagnetic objects, are disclosed. Inputs provided from one or more magnetic sensors, such as three three-axis magnetic sensors, as well as from other sensors, such as accelerometers and gyroscopic sensors, may be used to determine magnetic field distortion indicative of ferromagnetic objects and provide output information corresponding to the detected object.

摘要： Lighting devices using selectively permeable barrier elements, graphite sheet materials, and/or browning agent destroyers/sequestering agents are disclosed. In one embodiment a lighting device may include a body or housing with a selectively permeable barrier element, such as a silicone membrane or o-ring to allow diffusion of contaminants from one or more interior volumes to the exterior environment. Contaminants may be mitigated through use of a sequestering agent/browning agent destroyer. Heat conduction between elements of the housing, such as to aid removal of heat generated from a lighting element such as an LED, may be improved through use of graphite materials, such as PGS sheets between housing elements.

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.
