摘要: Methods for processing signals from a magnetic user interface device having a manual actuator are disclosed. Movements of the actuator may cause relative movement between one or more magnets and one or more corresponding sensors that may each generate signals representing independent magnetic field components detected within each sensor. A field model may be used in the magnetic user interface device to translate magnetic sensor readings during operation to position information, which may then be converted to output signals for transmission to an electronic computing system representing displacement and/or deformation of the actuator. The output signals may be generated in a predetermined format, such as USB format or other computer-interface formats, that can be interpreted by the electronic computing system.

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: Magnetic locators for detection of buried objects, such as ferromagnetic objects, are disclosed. Outputs provided from two or more magnetic sensors, such as three three-axis magnetic sensors, as well as optionally from other sensors, such as accelerometers and gyroscopic sensors, may be used to determine magnetic field distortion indicative of ferromagnetic objects and/or provide output information corresponding to the detected objects based on the sensor outputs.

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.
